+"""The development cycle, checked.
+
+The knowledge flow (00-META/process/00-overview.md) says work moves idea -> research ->
+decision -> to-be design -> code, and symptom -> issue -> diagnosis -> fix. Those are rules,
+and a rule states how it is checked (AGENTS.md) -- this is how. Everything here reads only
+frontmatter, because a status this repository holds lives in frontmatter and nowhere else.
+
+What is enforced:
+
+  design  every 03-DESIGN doc parses, carries `layer:` matching its directory, and a
+          known `status:`. A TO-BE doc names at least one decision (`decisions:`) -- no
+          design without a decision -- and once `in-progress` or `implemented` it names
+          its owning code (`code:`) -- no development without a design that says where.
+  issues  every report has frontmatter, and no two records share a number -- the number is
+          how a record is cited. An issue's status, owner, fix and replay live in the issue
+          tracker since the import of slice 3 (ADR 0275, to-be 53), where `issue-tracker.move`
+          refuses at the write what this check refused at merge until then: a status outside
+          the five, `located` without an owner, `resolved` without a fix, a core issue
+          resolved without its replay (ADR 0237), `wontfix` without a reason. A report
+          carries none of those keys, only the day it was `opened:` -- the tracker holds
+          them, and two places holding one fact drift. The keys the reports opened before
+          the import carried were removed once the import held them; the commit it read
+          is on every imported issue.
+
+The decision records and research efforts live in the knowledge base (ADR 0290, issue 426), and the
+rules this check held over them are the knowledge base's now: a research effort's status and what it
+became, and a decision's duplicate number, are refused by `knowledge-base.propose`; an accepted decision
+cited by nothing is the knowledge base's whole-set rule `cited`; a deferral that names no issue is its
+rule `deferral`. README.md beside this file says where each went.
+
+Deliberately NOT enforced: as-is docs need no decisions (they describe what exists, not what
+was decided).

+"""One word per thing, checked (ADR 0244).
+
+The glossary (00-META/glossary.md) is the authority on the mesh's words. It names the words it
+retired on one fixed kind of line, so a program can read them:
+
+    *Not:* ~~control plane~~, ~~overlay~~ (hq)
+
+A struck word with no scope is retired everywhere; `(hq)` retires it in this repository's prose only;
+`(tools)` in the descriptions of the mesh's tools only. And it names code that still carries an old
+name until that code is renamed:
+
+    *Identifier until renamed:* `mesh-host` — the repository, binary and service unit
+
+An identifier is allowed inside a code span and nowhere else.
+
+What is enforced:
+
+  retired      no retired word of scope `hq` (or none), and no identifier, in running prose of a
+               checked document. Running prose is what is left once code blocks, code spans, block
+               quotes, text in quotation marks, struck-through text, link targets, HTML comments and
+               frontmatter are taken out: a quotation keeps the words it quotes, a link target is a file
+               name, and an identifier lives in a code span. A word's plural is the word: "alerts" fails
+               as "alert" does.
+  unique       no head word (a bolded word opening a glossary entry) heads two entries, and no head
+               word is also struck through on a *Not:* line.
+  tools list   with `--list tools` it prints the words retired in the tools' descriptions, which is the
+               copy the catalogue's own check keeps (mesh-catalog `retired-words`). With
+               MESH_CATALOG_DIR set to a checkout of the catalogue it also fails when that copy differs.
+
+  lines        no daemon's line in a checked document (ADR 0272, its insight of 2026-10-09). The operator
+               types one command, `nox` (`mesh-cli`); the node-engine (`nox-mesh-host`) and the
+               controller (`mesh-controller`) are daemons, and a person never types their names — so a
+               document names a `nox` line, never `mesh-controller push` or `mesh-host hand-over`. The
+               lines are DAEMON_LINES below: each daemon's commands, and which of them are a line only
+               with an argument after them ("the mesh-controller module" is prose; `mesh-controller
+               module check …` is a line). A line is looked for in the document's own words — code
+               blocks and code spans included, since that is where a line to type is written — with
+               quotations, block quotes, link targets and comments taken out. `--list lines` prints the
+               list, which the catalogue's own check keeps a copy of (mesh-catalog `retired-lines`); with
+               MESH_CATALOG_DIR set it also fails when that copy differs. The node-engine's install-time
+               subcommands (`nox-mesh-host enrol`, `key`, `reconcile`, …) are not lines here: they are
+               typed at a machine no mesh reaches yet, and the engine's usage says so.

-// One word per thing, checked (words.py until ADR 0527; ADR 0244). The glossary (00-META/glossary.md) is the
-// authority on the mesh's words. It names the words it retired on one fixed kind of line, so a program can read them:
-//
-//	*Not:* ~~control plane~~, ~~overlay~~ (hq)
-//
-// A struck word with no scope is retired everywhere; `(hq)` retires it in this repository's prose only; `(tools)`
-// in the descriptions of the mesh's tools only. And it names code that still carries an old name until it is renamed:
-//
-//	*Identifier until renamed:* `mesh-host` - the repository, binary and service unit
-//
-// An identifier is allowed inside a code span and nowhere else.
-//
-// What is enforced:
-//
-//	retired  no retired word of scope hq (or none), and no identifier, in running prose of a checked document.
-//	         Running prose is what is left once code blocks, code spans, block quotes, text in quotation marks,
-//	         struck-through text, link targets, HTML comments and frontmatter are taken out. A word's plural is the word.
-//	unique   no head word heads two entries, and none is also struck through on a *Not:* line.
-//	lines    no daemon's line in a checked document (ADR 0272, its insight of 2026-10-09): the operator types `nox`.
-//	copy     with MESH_CATALOG_DIR set to a checkout of the catalogue, its copies of the retired words and the
-//	         daemons' lines equal this glossary's and this list (skipped, with its reason, when unset).

 - **merge window** — the rolling wait in which the controller collects merges before it plans them: each
   merge restarts it, and it closes when none arrived for its length (90 seconds by default) or at the latest
   10 minutes after its first merge (ADR 0276). Kept as two keys with a time to live on the bus; the first to
-  expire closes the batch (ADR 0407). Goes at release 6 of ADR 0429, when nothing collects merges (§12), and

+  expire closes the batch (ADR 0407).
 - **batch** — the merges one merge window collected, planned once as one rollout. For a repository merged more
   than once in it, the rollout takes the latest commit, and the earlier merges are answered by it. Not *group*,
-  which is a delivery group. Goes at release 6 of ADR 0429 (§11, §12): a merge moves the source revision and
-  nothing collects it; the word goes to a *Not:* line with the as-is update after that delivery.
-- **mesh-delivery** — the repository of the delivery domain, holding its parts as modules prefixed
-  `mesh-delivery-` (ADR 0429 §2), made by the forge module from its config (ADR 0428). Until release 3 of
-  ADR 0429 also the module in the catalogue that owns deliveries and delivery groups, holding the mesh-scoped
-  seat of the same name: it records and decides, and the controller sends, judges and rolls back when it is
-  asked. Release 3 splits that module into the parts, and then the name means the repository alone.
-- **part** — one independent process of the delivery domain with its own bus credential, which watches keys
-  and writes keys and never calls another part (ADR 0429 §1). Each key has one writer; the operator's
-  credential may also write a want, the one manual escape. The parts: the **forge bridge** (forge events in,
-  the only caller of the forge), the **indexer** (fingerprints, the candidates of a group, the modules of the
-  trunk), the **builder** (claims one fingerprint once and orders its build), the **checker** (the merge check on built
-  artifacts), the **gate** (merges a group and moves the source revision; *gate part* where it could be read
-  as another gate, see [Homonyms](#homonyms)), the **teller** (the operator's phone, and the only writer of an
-  ask's answer), the **assigner** (writes each node's wants by its seven rules, ADR 0539 §6), the **node
-  agent** (the node-engine's own process, applying its wants), the **watchman** (presence and pulses) and the
-  **status view** (`mesh-delivery-cli` and a web view, writing only its answers to asks and saying the events
-  `delivered`, `moving`, `settled` and `stuck`, derived from the keys). The reviewer is the review
-  agent's session, not a part. Built over releases 1 to 6 of ADR 0429.
-- **fingerprint** — what identifies a module's build by its content: a hash over its source files, its
-  manifest and the fingerprints of its build-time inputs, so equal content gives an equal fingerprint whatever
-  the commit (ADR 0429 §5). It is today's source fingerprint with a base entering by its module's
-  fingerprint, and a build resolving packages by its lock; from R4g the builder is no input of any fingerprint (ADR 0530). From
-  release 4 a build's key, so one source is never built twice.
-- **source revision** — one revision of the key `source.main`, written only by the gate: every repository's
-  merged head and the group that moved it. A group reaches the mesh as one source revision (ADR 0429 §11); a
-  source revision is **delivered** when every want equals its module's fingerprint and every have equals its
-  want and is healthy, derived from the keys and recorded by no part (§1).
-- **canary** — the first node of a module's nodes, ordered by ring then name: a new fingerprint reaches it
-  first and the module's other nodes only once it runs healthy there (ADR 0429 §6). Replaces sending to every
-  machine at once from release 6 (§15); a fingerprint that fails there is held and the canary set back, or for
-  a module that keeps data the operator is asked (ADR 0539 §18, §19).
-- **want** and **have** — a want (`want.<node>.<module>`) is the fingerprint a node should run of a module and
-  the digest of the one **composition** it allows for it, written by the assigner by its seven rules; the node's
-  own want `want.<node>.node` names its node composition (ADR 0429 §4, §6; ADR 0539 §1, §6). A want may also
-  carry the operator's answer to a failed backup (ADR 0539 §16). A have (`have.<node>.<module>`) is what the
-  node runs: the fingerprint, the composition's digest, its phase (`held` among them) and health, written by
-  that node's agent. A node's facts that no module owns are its node key. They replace rollouts at release 6,
-  and the assignments keep placement alone (ADR 0429 §17, ADR 0539 §12); haves are written from release 1.
-- **pulse** — a key the watchman writes for each key whose next move a machine owes, with a time to live; its
-  expiry is a stall, raised as a condition, so no part needs a timer (ADR 0429 §1, research 063). A person's
-  wait carries none.

+- **mesh-delivery** — the module that owns deliveries and delivery groups, holding the mesh-scoped seat

 - **rollout** — the controller's sending of one batch's builds across nodes, at most one trunk commit per
   repository, tier by tier, to every node that runs each module at once (ADR 0276, ADR 0360). Rollouts that share a
   repository, a module or a graph edge run one after another; others run side by side (ADR 0407). It names every
   merge it answers, and its record is one key of the bus's rollouts bucket, a link of the chain (ADR 0408). A primitive the delivering stage
   asks for, not an object anyone manages. A **tier** is one step of a rollout: a module, then the modules
   built against it. The controller's verb `plans` lists the rollouts. A module is rolled out by its `roll`
-  policy. Rollouts and tiers go at release 6 of ADR 0429 (§8, §15), replaced by wants and haves (§17); the

 ## The shape
 
 One feature is **one branch name**, **one worktree per repository**, **one pull request per repository**,
-opened **once**, after the review, and **one check** (ADR 0548). It runs in five steps, and its time is bounded. A milestone has no phases
-(the operator, 2026-10-17): these are its steps, and a report names the step it is in:
+opened **once**, after the review. It runs in five phases, and its time is bounded:
 
-| Step | What happens | Bound |
+| Phase | What happens | Bound |
 |---|---|---|
 | 0. Prepare | the lead settles the open questions and writes one context file per repository | 15 minutes |
-| 1. Develop | one fixing agent per repository builds every issue locally, the whole unit suite before every commit, the integration tests compiled; nothing is pushed | the milestone's issues, 30 minutes each |
-| 2. Review | one reviewer reads all of it, the local commits, judging the integration tests by reading them against the code; reports go both ways; at most 3 rounds | 15 minutes |
-| 3. Check | push the reviewed heads once and open the pull requests together; the checker's one check runs the integration tests; no further review unless the check fails | one check run |
-| 4. Deliver | merge; the source revision moves, each module is built once and wanted on its nodes, its canary first | until the view says the source revision `delivered` |
+| 1. Develop | one fixing agent per repository builds every issue locally, unit tests only | 1 to 2 hours |
+| 2. Review | one reviewer reads all of it; reports go both ways; at most 3 rounds | 15 minutes |
+| 3. Check | push; the forge's merge checks run the integration tests; no further review | one check run |
+| 4. Deliver | merge; the delivery plan builds, publishes and sends the whole feature | its delivery plan |
 
-**One milestone is one release** (the operator, 2026-10-17). A milestone is developed whole, reviewed once,
-pushed once, checked once and delivered once. It is never cut into steps for its size or for time: every cut adds a review, a
-merge check, an Approve and a delivery of waiting, so the fewest cuts is the fastest. Nor is it cut for an
-order between its parts (the operator, 2026-10-22: "a milestone is a milestone, we shouldn't cut it"): which module
-reaches the machines before which is the assigner's rules' (a build and a composition before the want, a provider
-before its consumers, the canary before the rest; design 47), and that is what they are for. An order they cannot
-keep is a fault of the build and delivery system, opened as an issue there, never a cut and never a step a session
-takes by hand.
-A milestone is one piece of functionality, possibly spanning several modules, repositories and dependencies such as
-an SDK change (the operator, 2026-10-21). Its pull requests in every repository share the milestone's branch name,
-so they are one delivery group (ADR 0482, which holds that a change across repositories is one group, one plan and
-one Approve, and that its developer orders no release). Nothing of the milestone merges until every issue of it is
-built, reviewed and checked; then the one Approve releases it all as one source revision, the assigner's rules
-keep a provider before its consumers, and an SDK change is built into the modules that use it. A small fix found during the milestone rides in this
-group, as playbook [08](08-small-fixes.md) says.
+A feature that cannot be developed in about two hours is split into **steps**. Each step runs all five
+phases on its own; the next step starts only when the previous step's delivery plan is done. A step is the
+unit that ships, so nothing finished waits for work that is not.
 
-**One design is built at a time** (the operator, 2026-10-17). While the milestones of one design are being
-built, no milestone of another design starts: its issues stay `open`, and nobody moves them to `diagnosing` or
-`fixing`. The next design starts when the last milestone of the one being built is delivered. A
-lead who finds another design's milestone already in `fixing` asks its owner before starting its own. A small
-fix ([playbook 08](08-small-fixes.md)) and an issue that is in no design's milestones are not held by this rule.
+**Scope is fixed at phase 0.** An issue found during a feature goes to the next step or the next feature,
+never into the running one, unless it blocks the running one.
 
-**Scope is fixed at the prepare step.** An issue found during a feature never goes into the running milestone, unless it
-blocks the running one: it is fixed in between or right after the delivery, as the next paragraph says, or goes to the
-next milestone or the next feature.
+## Phase 0 — Prepare (the lead, larger model)
 
-**An issue opened along the way is fixed by the session that opened it** (the operator, 2026-10-21): it is never only
-listed under "Opened along the way" and left. A small one (one repository, about an hour) is fixed in between, as a
-small fix ([playbook 08](08-small-fixes.md)) while the milestone waits on a check, an Approve or a delivery; the
-rest are fixed right after the milestone's delivery, before the next milestone starts, together on one branch where
-they share a repository. Either way it stays out of the running milestone's branch and pull request, unless it blocks
-the running milestone, so the scope above holds. Only an issue in another design's milestones (one design is built at
-a time), or one that needs a decision or the operator first, waits, and the report says which and why. Each report's line "Opened along the way" says for every
-issue whether it is being fixed in between, after the delivery, or waits, and on what.
-
-## Step 0 — Prepare (the lead, larger model)
-
-1. **Name the feature once:** `feat/<slug>`, the same branch name in every repository it touches (but see the
-   exception for a new manifest word in phase 3: a release that must merge first has a name of its own). The
-   branch is never protected. **One milestone is one branch per repository** (the operator, 2026-10-17), with one
-   folder `.work/<slug>/`; never a second name for part of it (`-2`, `-step2`).
+1. **Name the feature once:** `feat/<slug>`, the same branch name in every repository it touches. The
+   branch is never protected.
 2. **Make the worktrees:** one per touched repository under `.work/<slug>/<repo>`, branched off `main`
    (`git worktree add .work/<slug>/<repo> -b feat/<slug> origin/main`). The lab beds find the other
    repositories by sibling path, so add the untouched siblings the lab reads as detached worktrees on
-   `main` (`git worktree add --detach .work/<slug>/mesh-tools main`), never symlinks. **A repository's own
-   clone stays on `main`** (the operator, 2026-10-17): no work is done in it and no branch is checked out
-   there, so a session that opens in it reads what holds now; fetch and fast-forward it before reading.
+   `main` (`git worktree add --detach .work/<slug>/mesh-tools main`), never symlinks.
 3. **Settle every open question** in the feature's issues before any agent starts: on the issue, through
-   the knowledge base, or by asking the operator. **Read what is decided before designing** (`knowledge-base.ask`):
-   a question about delivery, checks or builds is most likely answered in design 47 and its decisions already (the operator,
-   2026-10-26: "that is simply our delivery plan and milestones, we've already researched it"); propose new research
-   only for what no record decides. A fixing agent that meets an undecided design question
+   the knowledge base, or by asking the operator. A fixing agent that meets an undecided design question
    stops, and its run is spent again.
 4. **Write one context file per repository**, `.work/<slug>/<repo>.context.md`. It is what a fixing agent
    reads instead of rediscovering the code, and it is reused by every agent and every round:
    - the issues it builds, in order, each with: the files and functions it changes, the decisions it builds
-     with (quoted, with where each was decided), and its acceptance criteria (item 5), each with the test that
-     proves it;
+     with (quoted, with where each was decided), the test to write first, done-when in one sentence;
    - the repository's map for this feature: the packages and files involved, with one line each on what they
      hold, and the patterns to copy (file:line);
    - what not to touch, and what lands beside it in other repositories;
    - the local facts: the worktree, the branch, the check commands, a temporary directory for tests outside
      the home (`TMPDIR`), and the unit tests to run (never a database server: tests that need one are
-     integration tests, which the pull request's one check runs).
+     integration tests, which the forge's checks run).
    When the reading is large, a read-only agent on the smaller model answers the lead's exact questions with
    file:line, and the lead writes the file from its answers.
-5. **Write the findings into the issues** (the operator, 2026-10-17: the better the content of the issues, the
-   better work the agents do, and the less review is needed). Before any agent starts, each issue carries, with
-   `issue-tracker.note`: every file and test that touches the change, found by search and not from memory
-   (file:line); **every other reader and writer of each value the change adds or changes** (a field, a key, a kind
-   of record), each with what it does with the new value, and a criterion for each that could treat it wrongly
-   (2026-10-19: the router's sync with the controller ended every condition the controller did not list, and the
-   survey, which followed only the new condition's own path, never named it); how the change is checked and delivered end to end (which test proves its done-when, which
-   modules its merge moves, read from the indexer's candidates of its group, and to which machines); and for a
-   group, its merge order. The context file
-   points to these notes; an issue reread by another session or a later agent then holds what was found.
-   When the reading is large, it starts with a read-only survey agent on the smaller model.
-   **Each issue carries its acceptance criteria, written by the lead** (the operator, 2026-10-18: the larger
-   model writes them, and they guide every test). Each criterion is one sentence, given, when, then, about what
-   the module or the operator observes, never about how the code does it, and names the level of the test that
-   proves it: unit, integration (a bus, a store or a process started) or end to end (none exist yet, so such a
-   criterion is proven live after the delivery and said so). Together they cover the issue's done-when and the
-   cases its life passes through: on 2026-10-18 mesh-delivery's group life (a group of three, a member's own
-   check, a close in a group, a second pull request at the same commit, a stop and a resend) had no criterion,
-   and each case was found by a failure on the live mesh. Each criterion is numbered in its note and cited as
-   `<issue>/AC<n>` (`1118/AC2`). They are an `issue-tracker.note` headed `Acceptance criteria`, a revision a new note that replaces the older one, until the tracker holds them as a
-   field (issue 1118). A criterion the reviewer adds in step 2 is written onto the issue the same way.
-   **The survey sizes each issue, and an issue sized over an hour is split before any agent starts** (the operator,
-   2026-10-17), into issues of about 30 minutes each, one change each, in the order they land: the bound of a
-   fixing agent's issue is then a real bound. On 2026-10-17 one issue held four changes sized at four to six
-   hours; it ran past its 30-minute bound for over an hour, and the reports could only say "still on part D".
-6. **List every part the change reaches, before any agent starts**, so each is an issue of the milestone and
-   nothing is found on the way. Read, for each repository of the milestone, what it takes from the others and how:
-   the SDK's users (they pin an SDK commit, and a pin to a commit no branch holds is a download that fails later,
-   issue 1148); every program that parses a manifest strictly (search `ParseManifest` across every repository, with
-   the SDK commit each pins), which must take an SDK that knows a new manifest word (2026-10-21: design 60's
-   catalogue milestone found mesh-build-go and the delivery's indexer reading manifests with an SDK from before the
-   word); the SDK's list of a defined seat's verbs, which must name a verb a module adds (2026-10-21: node-files' two
-   new verbs were refused on the claim); the node-engine's decoder for a new key on the wire; the route by which a
-   repository's first module registers; and a part that needs something the bus or a manifest cannot yet give, which
-   needs its decision first. Each such part is an issue of the milestone and its pull request a member of the group;
-   the order in which they reach the machines is the assigner's rules' (the operator, 2026-10-22), never a cut.
-   Where those rules cannot keep an order (a node told of a key before it reads it, a module using a word before its
-   readers are delivered), that is an issue of the build and delivery system, opened with `issue-tracker.open` and
-   said to the operator.
-7. **Write fixtures from the shape the other side writes, never from memory** (2026-10-18: a watchman's tests
-   mirrored a build key the controller never writes, and every test passed): copy a value from the writer's code or
-   from the live bus, and name where it came from.
-8. **Answer three questions in the milestone file** (`.work/<slug>/milestone.md`; research 071, issue 1941), written by the
-   lead from this template before any agent starts. Each answer is a fact found, not a hope:
-   ```
-   Lifetime of what the work creates (research 071, a):
-   - <bucket key or stream> | written by <module> | deleted by <module> on <event>, or time to live <duration>
-   (one line for every key-value bucket key and stream the work creates or starts writing; "none created" if none)
-   Trying the switch-over on one node first (b):
-   - <which node goes first, and what is read there before the rest>
-   - or: the operator chose no first trial on one node, on <date>; what that risks: <one sentence>
-   Integration level (c):
-   - <the one check that runs it: the group's pull requests, one check each, none before the review>
-   - what the check does not cover: <the parts of the group that meet only live>
-   ```
-   A key or stream with no one who deletes it and no time to live is a leak and is settled before work starts.
-9. **Move the issues to `fixing`**, `by` naming the feature's agent for that repository.

-## Step 1 — Develop (one fixing agent per repository, smaller model)
+## Phase 1 — Develop (one fixing agent per repository, smaller model)
 
 - **One agent per repository, kept for the whole feature.** It reads its context file once and builds the
   issues one after another, committing each locally with a message naming the issue ("Keep the assignments
   on the bus (issue 652)"). It is not replaced per issue: the lead continues the same agent (by its id) with
   the next instruction, so its context is paid for once.
-- **Unit tests only, each well under a second** (how-we-build §5, ADR 0391). **The whole unit suite runs before
-  every commit** (the operator, 2026-10-17), not only the tests of what changed: it takes under a second, and a
-  change breaks tests in packages it never touched. Each issue's first test fails before its change, on an assertion about what the
-  code does, and passes after. **A test that fails only because it does not compile has not failed first**: where
-  the test calls what the change adds, the agent takes out the change's effect (the line that does it, not the new
-  function), sees the test fail, and puts it back (2026-10-19: a check request's new field was proven by a test of
-  its helper alone, and dropping the field from the request passed every test); `gofmt`, `go vet` and the whole unit suite stay green. **The tests are written from the issue's
-  acceptance criteria**: one test or more per criterion at the level it names, each test's comment citing
-  the criterion it proves by its label (`// 1118/AC2`), and no criterion left without its test; an integration criterion is a test
-  that compiles and is run by the pull request's one check. The integration tests (those that start a store, a bus
-  or a process) are compiled with `go vet -tags integration ./...` while developing and run by that check, nowhere
-  else.
-- **Nothing is pushed and no pull request is opened in this step, and there is no try** (ADR 0548; the operator,
-  2026-10-26: "every release should only run 1 check or 1 try"). When every issue is committed, the lead brings each
-  feature branch up to the current trunk (fetch by name, then merge) and the review reads the local commits. Never call
-  `mesh-controller.try`, `mesh-delivery-checker.try` or `mesh-delivery-checker.checker_try`; one is run only when the operator asks for it. A reviewer
-  or a session that wants the code on the forge may push a branch that has no pull request: it runs nothing. Never land
-  on a red check: read the result, then land in a separate step.

-1. **The reviewed tree is the tree that is pushed**: every feature branch was brought up to the current trunk
-   before the review (step 1). The check runs on the merge with the trunk as it is then, so a
-   trunk that moves later is met by the forge's merge check, not by another merge here. Every verdict names the
-   trunk it merged onto ("pass <head> on <trunk>"), and the lead reads that trunk against the repository's main
-   at once: a trunk behind main means the source revision (source.main) lags, and every check in that

    It says which round it is in ("round 1 of at most 3").
 3. **The report goes to the same fixing agents** that wrote the code, continued by their ids, so they fix
    with the context they already hold. Each answers the reviewer: what it changed, per finding, or why not.
-4. **Every new integration test is read against the code it drives.** Fixing agents only compile it, and no run precedes the review (step 1), so the reviewer judges it by reading; the check that follows shows whether it passed but not whether it proves what it says. The reviewer traces each step of each new integration test through the code (fixtures against the manifest rules, what the store keeps and reads back, who holds a seat), and says which steps it could not trace. On 2026-10-17 a new test failed on its first two runs, on a fixture and then on a fault of the change; reading it against the code after the first failure found another fault, which would have failed a run too. A review that finds a fault only by reading is the cheaper run. The reviewer also checks that each new integration test enters through the same path the live trigger takes, not through a state it writes by hand: on 2026-10-17 milestone 4's test saved its delivery plan directly, so it skipped the cut from a batch that every live plan takes, and it passed while the backup step never ran (issue 1086).

    may ask). After round 3 the lead stops and brings the operator what is left, with a recommendation.
-6. **The reviewer reads every acceptance criterion against its test**: each criterion has a test at its level
-   that would fail without the change, and no test proves less than its criterion says. A criterion missing
-   for a case the issue's done-when needs is written onto the issue (step 0, item 5) and is a finding; a test
-   missing for a criterion is a finding.
-   **A rule keyed on a property is checked against everything else on the mesh that has it.** When a change
-   decides by a property the bus or the store gives (a stream's retention, a folder's name, an account's kind),
-   the reviewer lists what else already has that property, live, and asks what the rule does to it. On
-   2026-10-19 release 1 of feature mail-sender made a work-queue stream's dead letters drop-only by the bus's
-   work-queue retention; three review rounds passed it, and only its try showed that every seat's work stream has
-   that retention too, so dead asks across the mesh would no longer have been delivered again (issue 1178, fixed
-   before its pull request by a mark only a declared module work queue carries).
-6a. **The reviewer reads the milestone file's three answers** (step 0, item 8) against the change: it lists every bucket
-   key and stream the diff creates or writes (search the diff for the bucket and stream names) and finds each in the
-   lifetime answer with a deleter and event, or a time to live; it reads the switch-over answer and checks it was done as
-   written or that the operator's choice is recorded; it reads the integration-level answer against the check the pull requests will ask. A missing answer, or a key or stream the diff creates that the answer omits, is a change asked.

    further case, a nicer form: the reviewer opens it with `issue-tracker.open` and names the number in its
    report, and the round does not wait for it. What a round asks is only what makes the change wrong against
-   its issues, their acceptance criteria and its decisions.
-8. **A timer that writes state, or a rule fixed in code that overrides what a person sets, makes the change
-   wrong.** The mesh is NATS-native: a part says what happened as an event and acts on events; nothing polls
-   and rewrites state on an interval, and a policy the operator can change is a setting the module declares,
-   never a constant. The reviewer reads every new or changed interval, ticker, sleep loop and periodic
-   run-once in the change and asks of each: what event should drive it instead, and what setting turns it off.
-   One with no answer is a change asked. On 2026-10-23 the forge module's loop rewrote every repository's
-   branch protection every ten minutes from rules in its code and undid the operator's changes at the forge
-   (issue 1903).
-9. **At the second instance of a fault kind in a review, the developer searches for every instance and names each in the
-   report.** On 2026-10-25 a "busy, return at once" guard that dropped a newer request was found in three places,
-   one review after another. The developer writes the kind in one line, searches the repository (`git grep`) for
-   its shape, fixes every hit in one change and lists each file and line in the report. How it is checked: a

+## Phase 3 — Check (no review)
 
-1. **Push the reviewed heads once, then open one pull request per repository, together** (ADR 0548; the operator,
-   2026-10-26: "every release should only run 1 check or 1 try"). **No pull request, draft or not, exists before the
-   review approves the heads**, and no fix round is pushed to an open pull request: every push to an open pull request
-   asks a new check, of every member for a group, and the mesh's build capacity is spent on it ("we don't have more
-   processing power"). The integration tests run once, in the checker's merge check on the merge with the trunk's head, at the unit
-   and the integration level, through the build module of the repository's language and by that language's convention
-   (ADR 0445, ADR 0529); the check waits on the language's check stream until a build node has a free slot
-   (ADR 0525 §1). **No try:** never call `mesh-controller.try`, `mesh-delivery-checker.try` or `mesh-delivery-checker.checker_try`, except when the
-   operator asks for one. While developing, no `go test -tags integration` run of a whole level, and no store or bus started
-   by hand on the machine (the operator, 2026-10-18).
-   **A group is one check.** Before the push, every member pins the group's own mesh-sdk head exactly (the checker refuses an
-   older commit of the same branch), then all members are pushed and opened together, so the group's check runs once. A head the review replaces
-   counts for nothing against a running check; say so, and ask no other until the new head is reviewed.
-   **Before a session trusts an agent's "pushed", it reads the forge branch's head** (`git ls-remote origin refs/heads/<branch>`) and compares it with the commit reviewed; an agent may commit on a detached HEAD and report a push that never happened (2026-10-26: the first check of a reviewed fix failed "not our ref"). The pull request is opened only on that read head. Pull requests in two or
+1. **Push every feature branch and open one pull request per repository, together.**
+   The integration tests
+   run only in the merge check (the operator, 2026-10-16), never before. Pull requests in two or
    more repositories that share the branch name are one delivery group (ADR 0239 §2).
-   **A temporary mode that merges by hand** (the lead merges because the normal Approve and merge path is not
-   running): the pull request's one check still runs the integration level, and the lead names its verdict in the
-   pull request's description. A try with tests `.` is asked only when the operator asks for one, and then named there with its id and verdict (research 071).
    Where a session pushes through the forge tool `gitea_commit` (one commit on the forge's current base), the
-   reviewer first confirms that commit's tree equals the reviewed one. **A large change is pushed by a pusher agent** on the smaller
-   model: `gitea_commit` patches of about 30 KB each, a file copied from another path sent as a copy (`copy_from`)
-   and not as its bytes, and the forge's tree compared with the local one after the last part (2026-10-20: R4c-2's
-   two repositories went up in parts this way, and the lead's own context stayed free for the review). **Each pull request's description carries
-   the review record** (ADR 0421 §5), one line the lead writes from the reviewer's approval:
-   `Reviewed-by: <who@node> at <full sha>` (the issue 1022 note gives its form). mesh-delivery reads it at every new
-   head and puts it in the Approve's ask; a missing line, or one naming another commit, is said first in the ask.
-   It is never a gate. **Beside it, the description names the session that pushed the head**, one line
-   `Pushed-by: <who@node>` (ADR 0505 §5): when the head cannot merge because its check failed after the Approve (a
-   conflict, a failed check, a rejected group), the cure is that session's new head, and mesh-delivery tells the
-   operator only after two hours with no new head, naming the branch's author and this session. The session that
-   pushed watches its own pull request (the instruction follow-what-you-start) and pushes the new head well inside
-   those two hours. A description without the line names the branch alone.
-   **The description names its issues as `issue <n>`, and only its own** (2026-10-21: okioki #9 listed its four
-   issues bare, `Issues: 1608, 1646, …`, and named a milestone-2 issue as `issue 1654` and a follow-up as
-   `issues 1665, 1666, 1667`, so mesh-delivery carried 1654 and 1665 as the pull request's issues and the Approve's
-   ask named them): mesh-delivery takes a pull request's issues from the words `issue <n>` and `issues <n>` in its
-   description (the plural yields its first number only), so write `issue 1608, issue 1646`, and name any other
-   issue in words, never by `issue <n>` or `issues <n>`.
-   **A catalogue pull request that removes a module, or a subject a module names, is also judged by the
-   controller's unit tests against the catalogue's branch**, because those tests read the catalogue and no check
-   of the catalogue runs them: on 2026-10-20 mesh-catalog #381 removed the old delivery module, and every
-   controller check failed afterwards on a test of the catalogue's subjects until issue 1406 removed the name
-   mesh-issues still listened to. A controller's check does not find it, since a check reads the catalogue's main
-   (also in a delivery group that holds the catalogue's pull request); the lead runs mesh-controller's unit
-   suite with `MESH_CHECK_BESIDE` naming a directory that holds the catalogue's branch, as mesh-controller's
-   `internal/beside` says.
-2. **The checker's merge check runs the integration tests once, as the gate** (its one status, `mesh/check`). No
-   second review: step 2 reviewed this tree.
-3. **A check that fails** goes back to the same reviewer, continued by its id, with the failure, for **one more cycle** of step 2 with
-   the same fixing agents; then push **once** again (the one more push of ADR 0548). The check is **read, never re-asked to see if it passes**: a
-   check asked again without a new, reviewed head spends the build capacity for nothing. **The failure is read from the check's whole log**, never
-   reasoned from its summary: `mesh-delivery.show` names the check's build id, and `mesh-controller.builds` with
-   `log` set to that id prints everything the builder said. A check's summary picks only some failing lines;
-   on 2026-10-17 it showed a store test's `FAIL` without its cause, and a fix was first guessed from the code.
-   **A failure the check hides or loses** (a verdict naming only the first failed test, a log not kept) is a fault of the
-   checking tool: it is fixed there, the same turn (instruction fix-a-bug-met-twice), not asked around.
-   **A change to the Go build module's recipe is judged by the build module the nodes run**, not by the changed one, so a
-   test the change adds must pass under either version. **A change that needs the new recipe to judge it ships the recipe
-   first, as a small fix of its own**, and the rest waits for its delivery: on 2026-10-17 milestone 3 of design 47 moved its
-   integration tests behind a build tag in the same pull request as the script that ran that tag, and main's script would
-   have skipped every tagged test, its acceptance tests among them. Since R4g no repository holds such a script (ADR 0529):
-   which tests run at which level is the build tag's (ADR 0445 §2), and hq's checks are Go tests like any repository's
-   (ADR 0527). The prepare step looks for this: a change to what the checker's build module selects (its recipe, a build
-   tag convention) is cut ahead of the milestone.
-4. **The milestone's acceptance is proven by its check.** A milestone that adds or changes a module
+   reviewer first confirms that commit's tree equals the reviewed one.
+2. **The forge's merge checks run the integration tests once** (`mesh/merge-gate`, `mesh/repo-check`). No
+   second review: phase 2 reviewed this tree.
+3. **A check that fails** goes back to the reviewer with the failure, for **one more cycle** of phase 2 with
+   the same fixing agents; then push once again.
+4. **The step's acceptance is proven before it is marked ready.** A step that adds or changes a module
    carries an integration test that starts the module whole, its process against the real bus and store, and
-   shows the milestone's acceptance sentence; the forge's checks run it (ADR 0391 §1, §6). Unit tests alone are not
+   shows the step's acceptance sentence; the forge's checks run it (ADR 0391 §1, §6). Unit tests alone are not
    that proof; the mesh has no end-to-end tests yet, and the lab is not used (the operator, 2026-10-16).
-   **A new manifest word's test goes through the first composition that meets it, not only the verb that fills it.**
-   On 2026-10-19 release 1 of feature mail-sender tested a process's own bus account through `module issue`
-   alone; the first push after mesh-mail declared the process composed a random 40-character stand-in for the
-   account file before anyone issued it, and the process crash-looped until the account was issued and pushed by
-   hand (issue 1226).
-5. **The operator's Approve is asked as soon as the checks pass** (ADR 0421). Nobody marks, labels, comments or
-   rechecks: mesh-delivery asks the Approve on Telegram, the channel that proves who answered today (ADR 0398 §3;
-   an Approve at the terminal is issue 953), once its one check (`mesh/check`) passed, for a delivery group once for all its
-   members, naming the review record. On the Approve it merges the approved heads, a group's in one pass
-   (ADR 0418). A new head ends the Approve and is asked again once its checks pass, which is why a head is pushed only after its review. A watcher follows the checks,
-   the Approve and the merge, and wakes the lead. Beyond that
-   Approve, the operator's word is waited for only when the milestone changes what the operator sees, removes
-   data, or needs a step only the operator's terminal can take; the lead says which before the milestone starts.
-   **A pull request that depends on an earlier one outside its delivery group is opened only once the earlier one is delivered**, its build
-   running on every machine it should reach, not merely merged. A note in the description is no safeguard: the
-   operator's Approve merges whatever is asked. On 2026-10-25 a second change merged before the first was delivered
-   and machines lost modules. How it is checked: `mesh-delivery.deliveries` shows the earlier change's source
-   revision `delivered` before the later pull request exists (`gitea.gitea_get_pull_request`, its creation time);
-   a later one older than that is this rule skipped. Members of one delivery group are the exception: they open together, with one check, one Approve and one merge in one pass (item 1).
-   **A reviewed follow-up to a change the operator has not yet approved is folded into that pull request** (its head
-   moved to include it): one Approve, one delivery. The old Approve ask closes itself on the new head and the new
-   head is asked once its checks pass. How it is checked: a follow-up that sits in a second pull request while the
-   first still waits shows in `gitea.gitea_list_pull_requests` as two open pull requests of one lead.
+5. **The reviewer marks each pull request ready as soon as the acceptance is shown** with
+   `mesh-delivery.mark-ready` (the delivery of the head it approved, who reviewed it and why), which writes the
+   label `mesh/ready` and then `ready at <full sha>`, the order the forge counts (issue 913); mesh-delivery merges it when its checks pass
+   and the operator approved the merge into main on Telegram, the channel that proves who answered today (ADR 0364,
+   ADR 0398 §3; an Approve at the terminal is issue 953). Beyond that
+   Approve, the operator's word is waited for only when the step changes what the operator sees, removes
+   data, or needs a step only the operator's terminal can take; the lead says which before the step starts.
 
 **One exception: a catalogue change that uses a new manifest word.** The catalogue's merge check reads
 manifests with the controller the mesh runs, so the controller's pull request is merged and delivered first;
-then `mesh-delivery.recheck` the catalogue's and merge it on the new verdict. Such work is two releases, the controller's first, and playbook 04 cuts its milestones that way.
-**A new key the node-engine checks is such a word too** (issue 1051): the controller judges every machine with the
-node-engine's own validator, vendored at the commit `go.mod`'s `replace` pins, so a key added to the node-engine is
-refused by the gate until the controller's pin moves to the delivered node-engine (`go mod vendor`); the feature is
-then three releases, the node-engine's, the controller's, the catalogue's. **Every release that must merge before
-the catalogue's is on a branch name of its own** (`feat/<slug>-node-engine`, `feat/<slug>-controller`): on the
-feature's name it joins the catalogue's delivery group, and a group merges only whole, so neither merges.
+then `mesh-delivery.recheck` the catalogue's and merge it on the new verdict. Plan such a feature as two steps.
 The exception ends when milestone 3 of design 47 is delivered (issue 977, ADR 0402, ADR 0403): the group's composed
 check, judged by the group's controller, is then each member's gate, and the feature is one group.
 
-## Step 4 — Deliver
+## Phase 4 — Deliver
 
-The merge moves the source revision; there is no delivery plan (design 47, ADR 0539). The indexer writes each
-module's new fingerprint, the builder builds it once, the controller writes its compositions, credential and grant,
-and the assigner writes each node's want when its seven rules hold: the module's canary first, its other nodes once
-it runs healthy there. A merge into a branch other than `main` is not a delivery: no machine receives it.
-
-**The view follows a delivery; nobody asks the controller.** The lead's watcher waits on the status view's events:
-`moving` (a module's want on a node differs from its have), `settled` (the have reached the want, running and
-healthy), `stuck` (held, a failed health check, or past the watchman's thirty minutes) and `delivered` (every want of
-the source revision equals its fingerprint and every have its want). After each wake it reads the state again from
-the view's wants page or its tools: `assigner_wants` and `assigner_want` (a want not yet at the newest fingerprint
-names, in `newest` and `rule`, the rule that holds it back, and its words say why), and `node_haves` (the node
-agent's haves: fingerprint, composition digest, phase and health). The delivery is done when the view says
-`delivered` for its source revision; then the lead resolves the feature's issues with `fixed-by` naming its pull
-requests, and removes what is left: no `feat/<slug>` branch and no `.work/<slug>` worktree survive.
-
-**What a merge moves is read before the operator is told.** A change to mesh-sdk rebuilds every module that takes
-the SDK, with their backups and their asks for a person (issue 721): on 2026-10-20 the lead said an SDK merge moved
-nothing, and its delivery moved mesh-sdk with 41 dependents to all four machines. The lead reads the indexer's
-candidates of the group (the view's `indexer_candidates`: each module whose fingerprint the change moves) and the
-nodes that run them, and names what it moves before asking an Approve.
-
-**A held move is the operator's answer, asked by the assigner.** A module of policy `record` whose move would
-recreate a container or move data, a failed backup before an apply, and a data module whose new fingerprint failed
-its health check on the canary each wait for the operator's answer to the assigner's ask; the view says them
-`stuck`, and a condition names the node and the module. The lead reads the ask on the router
-(`operator-channel.asks`) before telling the operator it waits, and adds it to the wait list. No session writes a
-want to get past a hold.
-
-**A new module's first assignment is its first real composition.** The composition check composes every machine as
-it is assigned, so a module that no machine runs yet is composed by no check: on 2026-10-21 the build modules' first
-assignment found two faults no merge check could see (issue 1537, a template the controller filled for a value the
-forge serves only later; issue 1542, the node-engine refusing the module's own `.ssh`). So a new module is assigned
-to one machine first, its have read after the node agent applies it (`node_haves`: phase and health) and its node's
-answer read for a failed resource (`mesh-controller.node`), and taken back at once when that machine cannot compose
-or apply, so the machine keeps applying everything else; the other machines follow once it runs there.
-
-## Deliver the controller, the builder or a build module without the builder
-
-The builder delivers its own module, the build modules and the controller from its keys, and nothing falls back to another builder
-(ADR 0524 §7). When the builder or a build module cannot write references, or a controller cannot take its own fix (issue 1886: the
-controller's plan could never finish, and no plan it made could deliver its own fix), the way is ADR 0526's, in this order, each
-step recorded in the hand-act log with its reason:
-
-1. **Revert, with no build.** Revert the change that broke the builder or the build module: the earlier source's fingerprint has a done key naming
-   references, so the revert's delivery builds nothing. Read first that the artifact store still holds the earlier artifact
-   (`mesh-controller.artifacts`): it keeps a recorded build while it is among its module's five newest or a definition names it, and the
-   controller keeps its composition while it is among the five newest too, so the assigner's want delivers it.
-2. **A build by a session's call.** Call the build module's fetch and build tools on one named build node (for Go, `build_go_fetch` and then
-   `build_go_build` with `publish: true`); the build module pushes the artifact and answers its reference. `mesh-pack` in mesh-sdk gives a
-   hand build the build module's form; write the Go version of each hand build down, since another version gives another digest.
-3. **Register by reference, at the controller's terminal only.** The operator names the module, its repository, its path and each artifact's
-   reference there; no verb reaches it. Say before you ask that this is a terminal step, and which notifications it raises; check that the
-   command exists on the node before you hand it over.
-4. **A controller that cannot take its own fix** is put back by keys the operator writes at the terminal, with the operator's administrator
-   account (the operator's credential), never by a declaration sent by hand (ADR 0539 §10). To an earlier controller: the operator writes
-   `want.<control-node>.mesh-controller` naming a fingerprint whose composition is kept and that composition's digest; a controller
-   composes the one it replaced at its start, so that one is always kept. To a hand build never composed: register it as in step 3, then
-   `mesh-hand-compose` (in mesh-sdk, beside `mesh-pack`) composes the module for the control-node from the controller's kept inputs, signs it
-   with the operator's key, and with `-write` and the operator's credential writes the composition into `composed-<node>` and its digest
-   into `mesh-controller_composed`; the operator then writes the want naming that digest. Read the composition `mesh-hand-compose` prints
-   before `-write`. Each act goes into the hand-act log with its reason; say before you ask that these are terminal steps, and which
-   notifications they raise.
-5. **Before a switch that moves the controller, the builder or a build module,** the lead keeps the running versions' artifacts outside the
-   artifact store, by digest on two nodes, with module, artifact, commit, Go version and the steps that put each back; the store's nightly
-   collection removes a blob the controller did not record.
-
-Nothing here is a work-around for a delivery that can run normally: while the builder delivers, no hand act replaces it.
+The merge starts the delivery plan: build, publish, send. A merge into a branch other than `main` is not a
+delivery: no machine receives it (issue 889 while it still starts one). The lead follows it to done
+(`mesh-controller.plans` with `wait` and `until: done`), then resolves the feature's issues with `fixed-by`
+naming its pull requests, and removes what is left: no `feat/<slug>` branch and no `.work/<slug>` worktree
+survive.

-**Every wait on the list has a watcher** (the operator, 2026-10-17). A session runs only when a message reaches
-it, so a check, a merge, a delivery, a record's review or the operator's Approve on a channel that lands
-while the lead's turn has ended wakes nobody: on 2026-10-17 an approved group sat half merged for 14 minutes
-unseen (issue 1032). For each wait the lead starts a watcher, an agent on the smaller model that changes nothing,
-never the smallest (the operator, 2026-10-17).
-It loops `mesh_wait` on the event families of what it watches (`mesh-delivery-gate.transition` and
-`mesh-delivery-gate.group` for a merge, `mesh-delivery-view.moving`, `.settled`, `.stuck` and `.delivered` for its
-delivery to the nodes, for example; the families a watcher may wait on are those the mesh granted
-the tool runner, and a refusal names them) with a timeout under 60 seconds, since the call itself ends near
-a minute. After every answer or timeout it reads the state from the verb that owns it (`mesh-delivery.show`,
-the view's `assigner_wants` and `node_haves`, `knowledge-base.get`), because an event only wakes it (ADR 0367). It finishes, and so wakes
-the lead, when the state changes or the wait passes its bound. The lead never sleeps or polls by hand to wait.
-**A watcher watches one wait and ends with it.** It is never re-pointed at the next pull request or delivery: on

-and the lead told the operator for 15 minutes that they were still running. The next wait gets a fresh watcher,

-left, its frontmatter still saying `designed`, read to another session as not built, and a second design
-was started beside it (issue 1009, 2026-10-17). So the lead writes the design's state back at each of these
-moments, the same hour, an hq change going through [playbook 08](08-small-fixes.md):
-
-- **The first milestone starts:** the design's `status: in-progress` ([playbook 04](04-build-handoff.md) step 7),
-  if it is not already.
-- **A milestone is delivered** (the view says `delivered` for its source revision): its issues are resolved (step 4), with `fixed-by` naming its pull
-  requests. The design's milestone entry is not changed: it names the milestone's issues, and whether they are
-  delivered, when and by what is read from the issue tracker when it is asked, never copied into the design
-  (issue 1038; AGENTS.md: cross-cutting views are generated when they are read).
-- **The building pauses with work left** (another design takes its turn, a hand-over, the session's end): the
-  design stays `in-progress`, and each issue left gets a note with `issue-tracker.note` saying what it waits
-  for and what comes after it ("built after design N is delivered, before design M"). The first issue of
-  a design that waits its turn gets the same note.
-- **The last milestone is delivered:** [playbook 02](02-graduation.md), "When something ships": the as-is is

 ## The aim
 
 A small fix spends its time on the fix, and runs the long part once: **one review, one push, one check run,
-one delivery** (ADR 0548; the operator, 2026-10-26: "every release should only run 1 check or 1 try"; "we don't have more

    model answering exact questions with file:line). If a design question is open, it is settled before any

-   naming the level of the test that proves it, as an `issue-tracker.note` headed `Acceptance criteria`. A
-   playbook or design edit has none: its check is `go test ./...` at hq's root, which runs the four checks (ADR 0527).
+   decision stays a small fix.
 2. **Move the issue to `fixing`** with `by` as who@node.
-3. **Build on a local branch** `fix/<issue>-<slug>`, in a worktree of its own branched from `main`, never in
-   the repository's own clone, which stays on `main` (playbook [07](07-feature-branches.md), step 0, item 2). Write the
-   test that fails today first, on an assertion about what the code does: a test that fails only because it
-   does not compile has not failed first (playbook [07](07-feature-branches.md) step 1); make the change; keep `gofmt`, `go vet` and the repository's whole unit suite green
-   before every commit (each test well under a second; never a merge check or a database locally: how-we-build §5, ADR 0391).
-   Check that it compiles with `go vet`, never `go build` in a module's folder: with one main package it writes the
-   program beside `go.mod`, and `git add -A` takes it (issue 1577: two 5-10 MB programs committed on 2026-10-21,
-   caught only by the review); read `git show --stat` before pushing.
-   The tests are written from the acceptance criteria, at least one per criterion at its level, each citing the
-   criterion it proves by its label (`<issue>/AC<n>`, playbook 07 step 0 item 5). Commit, naming the issue. For a playbook or design edit, run the repository's own checks (in hq,
-   `go test ./...` at the root). The integration tests are compiled (`go vet -tags integration ./...`) and not run:
-   nothing is pushed, no pull request is opened and no try (`mesh-controller.try`, `mesh-delivery-checker.try`, `mesh-delivery-checker.checker_try`) is called, unless the operator asks for
-   one. A single integration test may be run locally against an embedded bus when it is the fastest way to find a cause.

    its id, so the fix keeps its context. A playbook or design edit of a few lines may skip the reviewer: the
-   operator's Approve of its merge is its review, and the review record says so.
-5. **Push the reviewed head once and open the pull request, only after the review approves.** The trunk is what runs and nothing holds merged work back
-   (ADR 0401), so a fix waits for no other change's delivery. No pull request, draft or not, exists before the review
-   approves the head, and no fix round is pushed to an open pull request: every push to an open pull request asks a new
-   check. The checker's merge check runs the unit and the integration level once, as the gate (playbook [07](07-feature-branches.md) step 3); the pushed head is read from the forge first, as playbook 07 step 3 item 1 says.
-   A failed check is read from its whole log (never re-asked to see if it passes), then the repository's whole integration level
-   is run locally (`go test -tags integration -count=1 ./...` in each module) so every failure shows at once, where a verdict
-   names only the first (issue 1921); the failures go back to the same agent, fixed in one change, the reviewer reads only the change
-   it makes, and the head is pushed once more.
-   **A temporary mode that merges by hand** (the lead merges because the normal Approve and merge path is not
-   running): the one check still runs, and the lead names its verdict in the pull request's description; a try with tests `.` is asked only when the operator asks for one (research 071; playbook
-   [07](07-feature-branches.md) step 3).
-6. **The pull request's description carries the review record** (`Reviewed-by: <who@node> at <full sha>`,
-   playbook [07](07-feature-branches.md) step 3) and the session that pushed it (`Pushed-by: <who@node>`, ADR 0505 §5), and mesh-delivery asks the operator's Approve as soon as its
-   checks pass and merges the approved head (ADR 0421); nobody marks, labels, comments or rechecks. A fix to a module that changes how it runs carries an
-   integration test starting the module whole against the real bus and store, run by the checker's one merge check
+   operator's word on the pull request is its review, and the lead marks it ready on that word.
+5. **Push once and open the pull request.** The trunk is what runs and nothing holds merged work back
+   (ADR 0401), so a fix waits for no other change's delivery. The forge's merge
+   check runs the integration tests, the only
+   place they run (the operator, 2026-10-16). A failed check
+   goes back to the same agent with the failure, and the reviewer reads only the change it makes.
+6. **The reviewer marks it ready at once** (for an edit that skipped the reviewer, the lead, on the
+   operator's word) with `mesh-delivery.mark-ready` (the delivery of the head it approved, who reviewed it and
+   why), which writes the label `mesh/ready` and then `ready at <full sha>`, the order the forge counts (issue 913);
+   mesh-delivery merges it when its checks pass. A fix to a module that changes how it runs carries an
+   integration test starting the module whole against the real bus and store, run by the forge's checks
    (ADR 0391 §1, §6); unit tests alone are not that proof, and the lab is not used. The operator's word is waited for only when the fix changes what the operator sees, removes data,
    or needs the operator's terminal.
-   **A fix that depends on another pull request outside its delivery group opens only once that one is delivered**, not merely merged (members of one group open together, as playbook 07 step 3 item 1 says) (a note
-   in the description does not hold it back: the Approve merges whatever is asked; 2026-10-25, machines lost modules
-   when a second change merged first). **A reviewed follow-up to a fix still waiting for the Approve is folded into
-   that pull request** (head moved): one Approve, one delivery. Both are checked as playbook
-   [07](07-feature-branches.md) step 3 says.
-   **At the second instance of a fault kind found in a review, the developer searches for every instance** and names
-   each in the report (playbook [07](07-feature-branches.md) step 2, item 9).
-7. **Follow its delivery to done**: a watcher waits on the status view's events (`mesh-delivery-view.moving`,
-   `.settled`, `.stuck` and `.delivered`) and reads the view's `assigner_wants` and `node_haves` after each wake, as
-   playbook [07](07-feature-branches.md) step 4 says; the delivery is done when the view says `delivered` for its
-   source revision. Then prove the fix on the mesh (the symptom gone, measured), and resolve the issue with
-   `located-in` and `fixed-by` the same hour.

+   the mesh (the symptom gone, measured), and resolve the issue with `located-in` and `fixed-by` the same hour.
 
 A fix that stops before its delivery moves its issue back to `open` with a note saying how far it got

-**An issue opened along the way is fixed too** (the operator, 2026-10-21). A fix's review, check or delivery that
-opens an issue (a remark outside the done-when, a fault met live) leaves it to the same session to fix: right after
-this fix's delivery, as a small fix of its own, or folded into the next one in the same repository. It waits only
-when another running milestone owns it, or it needs a decision or the operator first; the report then says on what.
-
 **A second fault found by the delivery.** When a fix's delivery shows a second fault that keeps the issue's
 done-when from holding, and that fault is in the same files, it is taken into the same issue as a second pull

-**Trigger.** A page or a screen the operator will use is about to be designed or rebuilt, or the operator judges
-one unusable. It runs before the decisions about its look are written and before any of its code: a page built
-first and judged after it ships is rebuilt (the operator, 2026-10-22, on design 59's mail page, judged unusable
-the day it was delivered).
-
-**Who runs it.** The lead of the design, on the larger model. Mockups may be drawn by an agent on the smaller
-model from the lead's brief. The operator picks; nobody else does.
-
-## What it produces
-
-- **The reference**: one mockup the operator picked, kept with the design as `NN-mockup/` beside its to-be
-  document. It is a direction, not a pixel specification: the build matches what it shows the operator doing,
-  in the order and the weight it shows, not its exact pixels.
-- **The decisions it needs**: what the pick changes about what the mesh keeps, shows or does, written as decision
-  records (playbook [02](02-graduation.md)) before the design's milestones (playbook [04](04-build-handoff.md)).
-- **An acceptance test in the operator's words**: the page is done when the operator uses it, on the devices they
-  named, for the work the mockup shows.
-
-## Steps
-
-1. **Gather what the page must carry.** A page whose direction needs research first starts at playbook
-   [01](01-research.md); this playbook then draws it. Read the as-is of what it replaces and the real shape of its data from the
-   mesh (how many items, how long a line, what is missing in practice), the operator's complaint in their own
-   words, and a short survey of how others solve it (a handful of products, one line each on what changes for
-   the person). Write it into the work folder; nothing goes on the mesh.
-2. **Draw three to five mockups with fixed data.** Each is one static HTML file that opens from disk: invented
-   data shaped like the real (names, amounts, lengths, a long subject, an empty sender), no backend, a mock script
-   only where an interaction is the point. Each mockup is a different direction, not a variation of one; each
-   shows a phone's width and a desktop's. One index page links them all.
-3. **Show them and ask one question.** Put the index on the machine the operator is at, and ask which direction to
-   keep, one question at a time with the lead's recommendation. A round's answer may be a pick, a combination of
-   two, or a change; the next round draws only that. Three rounds without a pick mean something the operator wants
-   is missing: ask what, before drawing again.
-4. **Make the pick the reference.** Copy it into the design's `NN-mockup/`, with every name, address, employer,
-   mail address, domain, provider and amount of the operator's own replaced by invented ones: hq is public. Say in the design that
-   the reference is a direction, and link it.
-5. **Write what is new as decisions,** each with the operator's Approve where it changes what they see, then the
-   design and its milestones. The design's acceptance tests end with the operator using the page live.
-6. **Hold the build to it.** The lead gives playbook [07](07-feature-branches.md)'s reviewer the reference with
-   the built page, at a phone's and a desktop's width, as part of what the review reads against the issue. The
-   operator using the page is the milestone's live proof, made before the next milestone starts (playbook
-   [04](04-build-handoff.md)).

-| Waiting on | Bound | Past the bound |
-|---|---|---|
-| a round of mockups | 1 hour | say to the operator what is taking long |

-- No code reaches the mesh during a visual design: mockups live in the work folder until one is picked.
-- Mockups use invented data, never a copy of the operator's mail, files or accounts.
-- The operator's pick stands over the lead's taste; the lead's recommendation is said once, with its reason.
-
-## How it is checked
-
-- A to-be design of a page the operator uses links its reference mockup in `NN-mockup/`, and that mockup holds
-  none of the operator's own names, addresses, domains, providers or amounts (read by the reviewer of the design's pull request).
-- The milestone's review read the built page beside the reference at a phone's and a desktop's width (its
-  report says so).
-- The design's last acceptance test is the operator using the page, proven before the next milestone starts.

 # Delivery — from a merge to the nodes, as it runs
 
-What runs on 2026-10-26, after the delivery of release 6 (milestone R6 of
-[to-be 47](../01-to-be/47-delivery-from-commit-to-delivered.md), ADR 0539), read from the code on each repository's
-main (`mesh-delivery`, the gate in `mesh-catalog`, the node agent in `mesh-host`, `mesh-controller`) and from the live
-mesh: the controller's seat verbs, `mesh-controller.modules`, the gate's `table`, and the view's `assigner_wants` and
-`node_haves`. Until 2026-10-26 this document described release 5, in which the controller still made a delivery plan
-for each merge, ordered it in tiers and sent whole declarations to the machines; none of that runs any more.
+What runs on the mesh's main branches on 2026-10-16, read from the code and the live record by research 055
+(findings 1 to 12). It is what [to-be 47](../01-to-be/47-delivery-from-commit-to-delivered.md) replaces, milestone
+by milestone. Until 2026-10-16 this document described the predecessor's pipeline, which no longer runs.
 
 ## Who does what
 
-- **The parts of `mesh-delivery`** are modules of one repository, each a process with its own bus credential that
-  watches keys and writes keys (ADR 0429). Running now: the forge bridge, the indexer, the checker, the teller and the
-  watchman on the control-node; the builder and the status view (`mesh-delivery-view`) on the workstation; and the
-  assigner on the home server. The gate (`mesh-delivery-gate`, holding the seat `mesh-delivery`) is a module of
-  `mesh-catalog` and runs on the control-node.
-- **The forge bridge** turns the forge's events into stream messages and is the only part that calls the forge; the
-  forge module (`gitea`) still announces them through the forge's system webhook.
-- **The indexer** writes each module's fingerprint at the merge preview and at a trunk merge; **the builder** claims a
-  build once per fingerprint and orders it as an ask on the stream of the artifact's language.
-- **The build modules** (`mesh-build-go` on all four machines, `mesh-build-node` on three, `mesh-build-image` on one;
-  ADR 0525) hold the node seats `node-build-go`, `node-build-node` and `node-build-image` and pull asks from the bus's
-  work-queue streams (deliveries first, then checks, then re-checks) while their node has a free slot of build
-  capacity.
-- **The checker** runs the merge check and writes the one status `mesh/check`, and serves a **try** on a pushed
-  branch. The forge requires no status on any repository (ADR 0534), and no repository holds a `merge-check.sh`
-  (ADR 0529).
-- **The gate** keeps one key per pull request and the merge's states only: `proposed`, `ready`, `rejected`, `held`,
-  `merged` and `closed`, read from its `table` verb. On the operator's Approve it merges a delivery group's pull
-  requests in one pass and writes their merged heads as one revision of `source.main`. It sends nothing to a
-  machine and asks the controller nothing.
-- **The controller** (`mesh-controller`, on the control-node) keeps registration, placement in its assignments
-  bucket and every node's inputs, and composes: on events it writes each module's signed composition for each node at
-  each fingerprint into the node's bucket `composed-<node>`, with its digest and its judgement of the move in
-  `mesh-controller_composed`, and it issues a module's credential and grant when its build is done. It plans,
-  orders and sends nothing: of its seat's 65 verbs, 20 are refused by name with their replacement, among them
-  `plans`, `plan`, `push`, `deliver`, `delivery-stop`, `delivery-order` and `delivery-walks` (read 2026-10-26 01:20).
-- **The assigner** writes each node's want of each module, `want.<node>.<module>`, naming a fingerprint and the
-  digest of the one composition it allows, when its seven rules hold: the build is done, the fingerprint is not
-  held, the node is the module's canary or the canary runs it healthy, at most `step` others ahead, every provider
-  runs healthy, the grant exists and the composition exists. In the code the canary is the first of the module's
-  nodes by name that is online (one ring), and rule 4 always holds, because the mesh keeps no `step`. It also runs
-  the composition check the checker reads. Its differences bucket, from release 5's comparison with what the
-  controller sent, is no longer written.
-- **Two ways around the rules, both by hand.** A **put** (ADR 0546), written by the assigner's tool `assigner_put`,
-  puts one version of a module on one node: while a put owns a node's want of a module, from its ask until it ends,
-  the rules pass over that want. And the operator's credential may write a want itself, with a composition the
-  operator signed and wrote through mesh-sdk's `mesh-hand-compose` (ADR 0539 §10).
-- **The node agent**, a process of the node-engine (`mesh-host`) on every node, watches its node's wants and its
-  bucket of compositions, and applies a module only when the want's fingerprint or digest differs from what runs,
-  and only the composition whose digest the want names, after checking its signature. It asks its node's
-  `node-backup` seat to back up a data module first and waits for the backup's end. It writes the have,
-  `have.<node>.<module>` in `node-engine_have`, with the fingerprint, the composition's digest, the phase and the
-  health. A failed apply is retried by the next change of the want or the composition; an apply that failed only
-  because the bus did not answer for a moment is retried with a bounded backoff, and at once when the bus is back.
-- **The watchman** mirrors every want as a pulse owed by that node's agent until its have names the want's
-  fingerprint, so a node that does not move shows as a stall.
-- **The status view** derives from `source.main`, the wants and the haves whether the source revision is
-  delivered, and says the event `delivered` once per revision, and `moving`, `settled` and `stuck` once for a
-  module on a node at one composition. The messenger holds the operator's notices on those events, and the issue
-  tracker hears `delivered`.
-- **The grants part** (`mesh-grants`, on the control-node; ADR 0547) publishes each assignment's membership on the
-  assignments stream when it differs from the one last published. The bus's user list, assertions and grants it
-  composes only in its own state, compared with what the bus holds, and they take no effect; the controller still
-  composes the user list the bus loads.
+- **mesh-delivery** owns deliveries and delivery groups (ADR 0239): one delivery per commit, a group per branch
+  name shared across repositories. It records each transition in its state on the bus (key-value buckets
+  `deliveries` and `groups`), marks pull requests, asks the controller to deliver, and merges a pull request marked
+  ready at its head once both required checks pass against the trunk's head (ADR 0364) and the operator approved
+  the merge into main on a channel that proves who answered (ADR 0398 §3).
+- **The controller** plans, orders, sends and judges. It computes a delivery plan for a repository and the files a
+  merge changes, moves only modules whose build source changed with their build dependents (ADR 0267), and
+  reuses a merge check's build of the same reuse key (ADR 0350).
+- **The builders** (holders of the build seat) take build requests and checks from a work-queue stream on the bus
+  and build inside a toolchain image another module provides, with the network off; on 2026-10-13 no node had Go
+  or npm installed (issue 626).
+- **The forge module** publishes every forge event on the bus through the forge's system webhook since 2026-10-14
+  (issue 729), and still polls the forge every 30 s, or every 300 s once it hears events. It keeps files of what it
+  announced so it does not announce twice.
 
-## From a merge to the nodes
+## From a merge to a rollout
 
-- A pull request's head is built and checked as it comes in; one status, `mesh/check`, carries the verdict, and a
-  delivery group has one verdict for every member. A move of the trunk asks the checks again, and a running check
-  stops itself when its head or trunk commit moves.
-- The gate merges on the operator's Approve and moves the source revision in one write. Nothing collects merges or
-  waits for others: the indexer writes the new fingerprints, the builder claims each new one once, the controller
-  composes and grants on the done build, and the assigner writes each want once its rules hold, the canary first.
-- Each node applies its own wants one module at a time and writes its haves; the source revision is delivered when
-  every want equals its module's fingerprint and every have equals its want, running and healthy. Read on
-  2026-10-26 at 01:20: 303 wants, every one equal to its node's have in fingerprint and composition digest, and 12
-  fingerprints held.
-- **hq** builds no module: the checker runs hq's Go tests (`go test ./...`) as its check (ADR 0527).
+- **The merge window.** The controller collects merges into an open batch; each merge restarts the window, which
+  closes after 90 seconds without a merge or 10 minutes after the batch's first merge (ADR 0276). A lone merge is
+  cut at once (ADR 0282 §2, as ADR 0304 §1 changed it). The batch and its merges are rows in the controller's
+  store, cut by a timer every 5 s, with a catch-up timer every 5 minutes for merges no batch holds.
+- **The rollout.** A closed batch becomes one rollout, at most one commit per repository, tiered along the module
+  graph. Rollouts run one at a time: a batch cut while a rollout is open is queued behind it, whatever it shares
+  with it. Running unrelated rollouts side by side (ADR 0282 §3, ADR 0304 §2) is decided and not built (issue 525). A rollout's builds go to every machine at once, with no first-machine gate, and the rollout ends on
+  the machines' reports or after fifteen minutes of silence (ADR 0360). A controller timer advances rollouts every
+  30 s.
+- **A merge during a rollout.** Its place in the next batch is a store row the open rollout's holder writes. On
+  2026-10-16, when another controller worked the plans, a merge was not recorded and waited until a person released
+  it (issue 921).
+- **"Release branches".** A pull request into a branch other than a trunk is judged by the controller built from that
+  branch (ADR 0358); feature 57 shipped about 37 packages that way over about 2.5 days and held the controller for
+  55.7 h.
+
+## Checks
+
+- Every pull request's head gets `mesh/merge-gate` (the composed machines) and `mesh/repo-check` (the repository's
+  `merge-check.sh`), each judged against one trunk commit (ADR 0323). A trunk move asks the check of every active,
+  cleanly merging pull request again (ADR 0395).
+- A delivery group's members are each checked beside their siblings' heads, and the group also gets a composed
+  check, `mesh/delivery-group`; each member keeps its own gate beside it (ADR 0382).
+- The queue's order (delivery builds first, then ready checks, then the rest) is kept by pausing the worker and
+  deleting and republishing a request (issue 558); an old head's check is ended after asking the forge for the
+  current head (issue 726).
+- mesh-delivery ticks every 10 s, reconciles with the controller every 30 s and polls the forge for ready marks
+  every minute, although the forge module already publishes labeled, commented and synchronized events.
 
 ## Where the record of what runs lives
 
-Fingerprints, builds, verdicts, wants and haves are keys in the parts' buckets on the bus; compositions are in each
-node's `composed-<node>` bucket, readable only by that node, with a file over 64 KiB in the object store; builds'
-files are in the artifact store by digest; packages are versions in the package registry. The controller
-still records every build it takes in, in its builds bucket (`RecordBuild` in `cmd/mesh-controller/key_takein.go`); its
-assignments bucket keeps placement alone, and its rollouts bucket keeps the record of releases 1 to 5 read-only, and
-nothing writes it now.
+Builds and build requests, rollouts with their tiers, batches and merges, and assignments are rows in the
+controller's store; artifacts are blobs in the artifact store by digest (ADR 0251); packages are versions in the
+package registry. The controller writes three record mirrors to the bus: assignments, declared config and
+predefined keys; of the five ADR 0289 §7 decided, the nodes, rollouts, builds and settings mirrors are not in the
+code. An assignment names its module and node but not the build, artifact or rollout that put it there: which commit
+runs where, and which delivery brought it, takes three verbs and a join by hand.
+
+No backup is taken before a delivery moves a module that holds data; backups run nightly and on demand (ADR 0214).
 
 ## What is not covered
 
-Nothing checks the delivery budget: the over-budget condition and the gate's `times` went with release 6, and no
-reader of the view's `settled` and `delivered` events measures it yet (issue 1945, note 10). The bus's own move stays
-a person's step through the controller's `bus` verb (ADR 0539 §15). The checker's left-running keys of build modules
-that stopped (`checker_status`'s `left_running`) are listed and hold no place. There are no end-to-end tests of
-delivery, and the lab is not used (the operator, 2026-10-16).
-
-## How it is checked
-
-- `mesh-delivery-view.assigner_wants` and `mesh-delivery-view.node_haves`: each want beside its have; `indexer_modules`
-  and `builder_builds` for the fingerprints and builds they name.
-- `mesh-delivery.table`: the gate's states and transitions; `mesh-delivery.deliveries` and `show` for one delivery.
-- `mesh-controller.seats` and `mesh_overview`: the controller's verbs, and which are refused by name.
-- The code: `mesh-delivery` (`modules/mesh-delivery-assigner/internal/assign`, `modules/mesh-delivery-view/internal/view`,
-  `modules/mesh-delivery-watchman/internal/watch`, `modules/mesh-grants`), `mesh-host` (`internal/agent`,
-  `cmd/mesh-host/nodeagent.go`), and the gate in `mesh-catalog` (`modules/mesh-delivery-gate`).
+The integration tests run only in each repository's merge check; there are no end-to-end tests of delivery yet,
+and the lab is not used (the operator, 2026-10-16).

 # The mesh MCP server, as it runs
 
-**The `mesh-console` container no longer exists.** Read 2026-10-17 from `mesh-tools` (package
-`node-tools`), `mesh-host` and `mesh-controller` on their forges' main, and from the live mesh
-through `mesh_overview`, `mesh_machine`, `mesh_runtimes` and `mesh_describe`. Checked: the
-catalogue (`mesh-catalog`) carries no module named `mesh-console` any more — the name survives only
-in the glossary's retired-words list and in a test fixture — and none of the four nodes answers a
-module of that name. How the tool runner reaches a node, its count of modules and tools and the
-controller's verbs were read again on 2026-10-26, after the delivery of release 6 (ADR 0539).
-
-## What it is now
-
-**The tool runner is one of the mesh's core components**, named `node-tools` beside
-`mesh-controller`, `mesh-host` (the node-engine) and `nats` (the bus) — the mesh's own repositories'
-check treats the four the same way, as the core whose health the mesh itself defines rather than a
-module's own. Since release 6 it reaches each node the way every module does: the controller composes
-and signs its composition for that node, the assigner writes the node's want of it, and the
-node-engine's node agent applies it and writes its have. What stays particular to it is the account
-named `<node>.node-tools` on the bus (`BusNodeTools` in `mesh-controller`) and the node-engine's
-witness and lease code that puts back a tool runner that does not come up (`ComponentNodeTools` in
-`mesh-host`, ADR 0360 §9).
-
-**It still carries a manifest, `node-tools/module.json` in `mesh-tools`,** and that manifest is
-where its grants live: `invokes` names `*`, so its account may call every tool on the mesh;
-`waits` names the five event families `mesh_wait` may subscribe to (the knowledge base's reviews,
-mesh-delivery's transitions, the forge's status, the controller's checked event, and the operator
-channel's decision for the agent module) — the bus refuses a subscription outside this list
-(ADR 0367 §2); and it
-`provides` one provision, the MCP endpoint, at node scope, and `listens` on the port it serves from,
-opened only to the machine itself. Its code lives under `node-tools/` in the `mesh-tools`
-repository (`internal/console`, `internal/announce`, `internal/bus`).
-
-**One runtime per node, run by the node-engine as a sibling process, never a container**
-(ADR 0175). It holds the node's one bus credential and may call every tool on the mesh; its account
-publishes nothing else. It binds `127.0.0.1:<port>` and refuses to bind anything else, said before
-binding rather than after (`node-tools/internal/console/http.go`, citing ADR 0152): whoever is on
-the machine owns the mesh there, and nobody else may reach this port. An agent or a person on the
-node is pointed at `http://127.0.0.1:<port>/mcp` once; the `serverInfo.name` the handshake answers
-is `mesh`.
+**The mesh's tools reach a person through a module the mesh assigned to their machine.** Since
+2026-09-30 a workstation that is a node can be assigned `mesh-console`; the mesh mints a bus account
+`<node>.mesh-console`, seals its credential to the machine, and the container binds
+`127.0.0.1:<port>` with the port the mesh assigned for the manifest's declared one. An agent on the
+machine is pointed at `http://127.0.0.1:<port>/mcp` and sees the mesh's tools; a person uses the same
+endpoint. Nothing on the machine holds a credential a person had to carry.
 
 ## What it answers
 
-`initialize`, `notifications/initialized`, `ping`, `tools/list`, `tools/call`, over HTTP, one JSON
-body per request, no session and no event stream (`node-tools/internal/console/mcp.go`).
+`initialize`, `tools/list`, `tools/call`, over HTTP, one JSON body per request, no session and no event
+stream. `tools/list` is what the running modules answered: every tool runner built on or after that day
+serves a `tools` verb for its module, and the mesh MCP server asks the catalogue for the roster and each module
+for its tools. A module that did not answer is named in the list's `_meta.notAnswering`. On the day it
+shipped that was 36 of 51 modules — those that serve no tools at all, and those whose rebuilt runtime the
+mesh records rather than rolls out — and 62 tools from the rest.
 
-**It announces seven tools, not five** (ADR 0195, extended by ADR 0367): `mesh_overview`,
-`mesh_machine`, `mesh_search`, `mesh_describe`, `mesh_call`, `mesh_runtimes` and `mesh_wait`. The
-handshake's `instructions` text names all seven and the four address forms. `mesh_overview` is
-where the mesh-wide count of modules and tools is read live — a number copied into this document
-would drift; asked on 2026-10-26 it answered 115 modules and 714 tools across the whole mesh, with
-two module instances (`route-proxy` on two of the nodes) named as not answering rather than silently
-absent.
+`tools/call` reaches any tool by `<module>.<tool>`, listed or not. The mesh MCP server's grant is `*`, so what it
+may call is every tool on the mesh; its account may publish nothing else and subscribes nothing.
 
-**Addresses, exactly as the handshake states them:** `<seat>.<verb>` for a seat held once for the
-mesh (`mesh-controller.status`); `<node>/<seat>.<verb>` for a seat every machine holds
-(`<node>/node-packet-filter.rules`); `<node>/<module>.<tool>` for a module assigned to one machine;
-and `<module>.<tool>` also for a module whose instances are interchangeable. A tool not listed can
-still be called by address — listing is discovery, calling is the grant — and a module that is not
-interchangeable is refused with the machines it runs on rather than guessed at.
-
-**What exists is what announced itself** (ADR 0197). Every node's tool runner answers the NATS services
-protocol's `$SRV.PING`, `$SRV.INFO` and `$SRV.STATS`, one service per process, naming in each
-endpoint's metadata which module, seat, scope and machine serves it. `mesh_overview` and
-`mesh_machine` gather one request's answers: at least 750ms so a runtime that only just answered
-`$SRV.PING` is still waited for, up to 5s for one that said it is there but has not yet sent its
-full announcement — a fixed shorter window lost the largest runtime's listing once a live
-measurement found how slow its round trip over the bus could be. An announcement unchanged since
-last asked (by its digest) is not re-fetched, which is why `mesh_runtimes` can show a runtime
-answering in under 100ms for hundreds of kilobytes of discovery.
-
-## mesh_wait
-
-**The seventh tool, added by ADR 0367**, lets a session wait on the bus for an event instead of
-polling: a call names one or more granted event families and an optional filter, and either answers
-the first match or says it timed out. The tool runner's own bus account hears only the families its
-manifest's `waits` list names; an event it hears is never taken as the state — a session reads the
-state from the verb that owns it once woken. It is meant to be called in a loop from a background
-command, not inline, because one call blocks until it answers or times out.
+No call is refused for want of a person's approval: a tool runner serves every call it is issued, whoever made
+it, and cannot tell an agent from the operator (ADR 0259 §6, issue 340). An act waits for the operator's warrant
+only where its module asks first, in its own code: the agent module's instruction proposals, and the
+controller's settings proposals and the actions it offers on a condition.
 
 ## The mesh's own verbs
 
-**These already answer directly, not as a stated future.** Beside every assigned module's tools,
-the tool runner asks the `mesh-controller` seat for its own verbs the same way (ADR 0154): measured
-live on 2026-10-26, the mesh-controller runtime is one instance, mesh-wide, and it answers 65 verbs for
-that one seat (`status`, `assign`, `modules`, `artifacts` and the rest), of which 20 are refused by
-name with what replaces them: the delivery verbs release 6 removed (`plans`, `plan`, `push`,
-`deliver` among them) and the build verbs of release 4 (`build`, `queue` among them). The `mesh-controller`
-*module* answers none of its own — it serves no module tools, only its seat's, exactly as design 33
-described while it was still only designed. The 56-to-93 seat-verb counts each node's tool runner
-answers (below) are a different thing: the tool runner serves the verbs of whichever node-scoped
-seats are held on that node (`node-backup`, `node-build-go`, `node-service-manager` among them),
-on behalf of the modules holding them, not the mesh-controller seat's — that one is served by the
-mesh-controller runtime itself, a separate process, and the tool runner only asks it and relays what
-it answers.
+*Since 2026-09-30 evening (ADR 0154).*
+The mesh MCP server asks the `mesh-controller` seat's `tools` verb beside the modules and lists every role's
+tools as `<seat>.<verb>` — `mesh-controller.status`, `mesh-controller.push` and the other ten. A call
+to `<prefix>.<name>` reaches the seat when the prefix is a seat declaring that verb, and the module
+otherwise; `seat:<seat>.<verb>` says so outright. When the controller does not answer, the list
+names `mesh-controller (seat)` as not answering and carries the modules' tools regardless. The
+`mesh-controller` *module* is always named as not answering: it serves no module tools, only its seat's.
 
-## Where it runs
+## Around it
 
-**Every node, not a per-operator assignment.** Measured live: all four of the mesh's machines
-answer a `node-tools` runtime, each with its own module and tool count (between 294 and 312 tools,
-56 to 93 seat verbs, in this reading). This is a fact that shipped past the design it came from: the
-to-be document still describes it as assigned to "whichever machines an operator sits at"; what
-actually runs is the opposite — every node the mesh holds carries one, because it is core
-infrastructure the mesh itself depends on (discovery, the controller's own verbs, every module's
-tools), not a convenience assigned to a workstation. There is accordingly no assign or unassign verb
-for it: removing it from a node is not an operation the controller or the catalogue exposes.
+- **`invokes`** in a manifest is the grant. It is composed into the bus's user list exactly as a
+  person's account is; the mesh MCP server is the only module that declares it.
+- **`module check <file|dir>…`** on the controller's binary judges a manifest with no mesh: the strict
+  parse, every per-manifest problem, and the rules between the manifests given. It prints what it cannot
+  judge without a store rather than refusing. The mesh MCP server's own manifest was the first thing checked
+  with it, and the whole catalogue passes.
+- **The person's client remains.** `operator issue` and `mesh tools|call|mcp` with a credential file
+  still work, for a machine that is not a node and for a mesh not yet able to assign anything.
+  `mesh tools --console <url>` goes through a running mesh MCP server with no credential; it is covered by the
+  runtime repository's tests and was not exercised on the live mesh.
 
-## What this repository's prior text got wrong
+## What shipped bent
 
-The document this replaces described `mesh-console` as a catalogue module served by a container and
-assigned only to workstations. That module and its container are gone; the manifest is not — it
-moved to `node-tools/module.json`, still declares `invokes: ["*"]`, and gained `waits` and the
-`mcp-endpoint` provision, described above. What also moved is which language builds it: the
-manifest's `build.artifacts` names a Go binary built from `cmd/node-tools`, and that is what a node
-runs. The repository still carries the earlier TypeScript sources (`node-tools/src/mesh.ts`,
-`http.ts`, `runtime.ts`, `announce.ts`, `broker-nats.ts`, `client.ts`, `launch.ts`, `main.ts`,
-`mcp.ts`) on main, but the manifest does not build from them. The quirks the prior text recorded
-from the `mesh-console` era (a module registered by hand recording its source as a URL; a
-*record*-policy module staying listed as not-answering until its rebuilt runtime is pushed) are not
-re-checked here: they were about the `mesh-console` container's registration path, which no longer
-exists.
-
-## How it is checked
-
-- `mesh_overview` and `mesh_machine <node>`: the live tool and seat-verb counts, and which modules
-  are named not-answering.
-- `mesh_runtimes`: which runtimes answered discovery, how long they took, how large their
-  announcement was, and whether it was shortened to fit the bus — read this when an address is said
-  to be missing or on another machine.
-- `mesh_describe <address>` for one tool's schema; a call through `mesh_call` reaches the module or
-  seat over the bus and the answer is its own, unshaped.
-- The code: `mesh-tools` (`node-tools/internal/console`, `internal/announce`, `internal/bus`),
-  `mesh-host` and `mesh-controller`'s core-component handling of `node-tools` (witness, lease,
-  bus-user naming). Their unit tests hold the loopback-only refusal, the seven-tool handshake, the
-  discovery gather window and `mesh_wait`'s event-then-read-state rule.
-- `knowledge-base.get` with `kind: decision` and number 152, 175, 195, 197, 367 or 154.
+- A module registered by hand from the catalogue with `--source <url> --path modules/<m>` records a URL,
+  not a place on the git seat: `--self` takes the forge path form (`<owner>/<repository>`), which the
+  operator did not pass. The rebuild-on-merge matched the URL anyway.
+- Modules whose upgrade policy is *record* — the forge among them — answered `tools` only once
+  something pushed their rebuilt runtime; until then they are listed as not answering while still
+  callable. That is the policy doing what it says, not a fault of the mesh MCP server.

-# Accounts on a machine, as they run
-
-**A node record names at most two logins: the operator account, always, and an agent account, on one node of
-four. Where a node names no agent account, agents run as the operator account. Nothing ties an identity to a
-login, and a module that needs one declares it itself.** Read on 2026-10-17 from the controller's and the
-catalogue's code on main (both local clones were a few commits behind the forge, so each claim below was
-also checked against a live read) and from the live node records. The change planned in ADR 0411 to 0414
-replaces this document when it is built.
-
-## The node record
-
-- **The operator account is stated at the controller's terminal** with `node account <node> <account> [home]`.
-  It is the person's login on that machine. The controller refuses to set it to the node's agent account.
-- **The agent account is stated at the controller's terminal only** with `node agent-account <node> <account>
-  [home]`, and cleared with `--clear`. It is no verb and no setting, so an agent cannot name itself one
-  (ADR 0266 §1). The controller refuses root, a malformed login, a well-known service account and the
-  operator account.
-- **Five machine facts come from the record.** `account` and `account-home` are the operator's, absent when
-  the node has no operator account. `agent-account` is the agent account, or the operator account where none is
-  named; `agent-home` is its home (`/home/<account>` when no home is stated); `agent-root` is `never` only where
-  the node names an agent account of its own, otherwise empty. Modules read them as `${machine:...}` words.
-- **One node of four names an agent account today**, the control node. The workstation, the laptop and the
-  home server name none: `mesh-controller.node` says there "agents run as the operator account; no agent
-  account is named", and the plan for the workstation declares the `claude-code` account resource with the
-  operator's name and no `root` field. The tool runner also receives `MESH_AGENT_ACCOUNT` and `MESH_AGENT_HOME`.
-- **Not verified:** whether the mesh-config snapshot carries either account. The controller's code reads both
-  from its own node table (columns for account, account home, agent account and agent home); no second place
-  that states them was found.
-
-## What claude-code does with the agent account
-
-- **It declares a `user` resource** named `${machine:agent-account}` with home `${machine:agent-home}` and
-  `root: ${machine:agent-root}`, and a `~/.claude` directory under that home owned by it, mode 0700. On the
-  control node the plan holds the resource with `root: never`; elsewhere it holds the operator's account.
-  Where the account is new, the mesh creates it with a home, its own group and no password (ADR 0266 §2).
-- **`claude-agent`** is a file the module writes at `/usr/local/bin/claude-agent`. Run as the agent account
-  it starts `claude`; run as any other account it runs `sudo -iu <agent account> claude` through that
-  account's own sudo, carrying the operator's guard override only if it is set in that shell. The file
-  `/etc/claude-code/agent-account` holds the account's name.
-- **The guard of ADR 0266 §28** is the module's hook on every tool call. On a node with an agent account
-  of its own it refuses each call of a session that runs as another account, with no override, and tells the
-  session to start with `claude-agent`. Its record goes to the machine's journal. The same guard also refuses
-  ssh to a mesh machine and writes to `/etc/hosts` and the resolver file (ADR 0245).
-- **Not verified live:** this rests on the guard's code and README, not on a refusal seen on a running machine.
-
-## The judgement that the agent account cannot become root
-
-- **The node-engine judges `root: never` on every look**, by reading only: uid 0, a group that grants root,
-  a sudo, doas or polkit rule, a container runtime's socket or API port, a secret the mesh placed for another
-  account, a setuid program no package owns, and kernel link protection off (ADR 0266 §12 to §16). A way found,
-  or a question unanswered, makes the account resource unhealthy. It does not prevent any way to root.
-- **The controller's self-check holds** that a node naming an agent account has it judged, in a verdict heard
-  within 15 minutes, as unable to become root (ADR 0266 §21 to §22). Otherwise it raises the urgent condition
-  `agent-can-become-root`. `mesh-controller.node` shows the verdict: for the control node it reads "cannot
-  become root without a person", judged the same day.
-- **On the three nodes without an agent account** the check does not apply. The controller instead holds an
-  urgent condition `root-not-free` on each machine that runs reads or the mail notifier. Two of the three are
-  silenced until 2026-10-23 on the operator's decision; the home server's is open and not silenced.
-
-## The accounts agents push as on the forge
-
-- **Today the forge has a user per machine**, made by the gitea module's `forge-account` provision and
-  holding that machine's key, plus a write token the module still mints for each (ADR 0398, ADR 0400). ADR 0410
-  decides one forge user, `nox-agent`, in the agents' write team, each machine's key titled by machine. No tool
-  reads the forge's user list, so whether `nox-agent` exists yet is **not verified**.
-- **The forge key is meant for the agent account** (ADR 0409 §2), but a module cannot run as that account:
-  the controller refuses it (issue 989, open). So the `ssh-client` module's key keeper still runs as the
-  operator account.
-- **An ordering deadlock** between `ssh-client`, which wants `forge-account`, and `gitea`, which provides it,
-  stopped every node's declaration from composing on 2026-10-17 at 00:35 until gitea was registered three
-  minutes later (issue 986). The four urgent conditions it raised were not observed again but stay raised,
-  because the controller's declaration check times out and never clears them (issue 992).
-  Git over ssh was proven from the laptop only; the proof on the other three, and retiring the forge token the
-  module still places, wait on issues 989 and 991 (the latter in `fixing`).
-- **Main stays closed**: a push to the main branch is refused, and a merge waits for a person (ADR 0398).
-
-## Logins on the bus
-
-Not here: see [`16-logins-on-the-bus.md`](16-logins-on-the-bus.md).
-
-## What it cannot do
-
-- **No identity carries a login.** An agent, a person and a module are not tied to an account on a machine;
-  the node record names a login per node and nothing else.
-- **A module declares a login itself.** Each module that needs an account writes a `user` resource of its own,
-  and nothing checks that two modules agree or that a login exists on every machine that needs it.
-- **Agent and operator share a login on three of four machines.** There the agent runs as the operator account,
-  which may become root; the guard's account rule does not apply, and the exposure is a held condition, not a fix.
-- **No per-agent bus password.** Every session on a machine calls through that machine's tool-runner login
-  (document 16), so one agent's calls cannot be told from another's.
-- **Detects, does not prevent.** The judgement above lists the ways to root it looks for; a way it does not list
-  is not seen (ADR 0266 §17).
-
-## How it is checked
-
-- `mesh-controller.node` with a node name: "agents run as" line, the verdict and when it was judged, the open
-  conditions (`agent-can-become-root`, `root-not-free`, `uncomposable`).
-- `mesh-controller.plan` with a node name: the `claude-code.agent-account` resource and its `root` field; with
-  `files` set, the files given, including `claude-agent` and `agent-account`.
-- `mesh-controller.conditions` for the held conditions; `claude_code_guard` for the guard's record, `claude-code`
-  tools for its status.
-- `knowledge-base.get` with `kind` decision and number 266, 409 or 410; `issue-tracker.get` with 989 or 991.
-- The code: the controller's node-record and agent-account files, and the `claude-code` module's manifest and
-  guard in the catalogue. Their unit tests hold the node record's refusals and the guard's account rule.

-## 1. The modules and their seats
-
-- **`mesh-mail`** claims `mail-store`, held once for the mesh (`accounts`, `search`, `read`, `send`,
-  `send-status`). It is assigned today to one machine, the control-node (`module.json`; confirmed live,
-  2026-10-20). ADR 0378 §4 decided to move it to the home server as a step of its own, on the operator's
-  Approve (issue 803); as built, that move has not happened: the live mesh still runs it, and `mesh-mail-web`
-  beside it, on the control-node.
-- **`mesh-mail-web`** is a module of its own, with its own Go module and source under `modules/mesh-mail-web`;
-  it claims `mail-webclient`, held once for the mesh. It is assigned to the same machine as `mesh-mail` and runs as its
-  own account, `mesh-mail-web`. Its manifest declares no database and no store of its own: nothing beyond its
-  route, its sign-in binding and its own settings on disk.
-- **`mesh-mail-notifier`** is a module of its own as well (`modules/mesh-mail-notifier`), and keeps a
-  byte-identical copy of `mesh-mail`'s `mailevent.go`, held to it by its `copies_test.go`, because each module
-  builds alone. ADR 0378 §9 and ADR 0440 §1 say both are "built from `mesh-mail`'s source"; as built, they are
-  separate modules that share none of `mesh-mail`'s own code but that copied file. It claims `mail-notifier`, held once per machine; a
-  module claiming it needs `node-notifier` held on the same machine (ADR 0378 §7). It is assigned today to two
-  machines, the laptop and the workstation (live read of each machine's modules, 2026-10-20); the control-node
-  and the home server hold no instance of it.
-- **`mesh-mail-reader`** is a module of its own (`modules/mesh-mail-reader`), with its own Go module and
-  source (`go.mod`, `cmd/mesh-mail-reader`), importing nothing of `mesh-mail` (`callers.go`). It claims `mail-reading`, a fourth seat `mesh-mail`'s own manifest declares beside its three mail
-  seats, held once for the mesh (ADR 0459 §1, §2). It is assigned to the same machine as `mesh-mail`, under
-  its own account, `mesh-mail-reader` (`runs-as`; confirmed live, 2026-10-22). It is covered whole in §8.
-- None of the four seats is named `mesh-*`. A caller reaches them by seat (`mail-store.<verb>`,
-  `mail-webclient.<verb>`, `mail-notifier.<verb>`, `mail-reading.<verb>`); `mesh-mail` also answers its own
-  tool names (`mail_accounts` and the rest) through the same handlers.
-
-## 2. Accounts and the MAIL stream
-
-- **Three accounts**, all of the kind `imap`, each a password-based sign-in given at the desk as the module's
-  own secret `mail-credential-<account>` — one against the mesh's own mail server, two against outside
-  providers (ADR 0359 §5, ADR 0361 §1; `mesh-controller.settings` for `mesh-mail`, read live on 2026-10-20). No
-  account's name or address is repeated in this document.
-- **It watches each account and says each mail on the bus.** `mesh-mail` keeps IMAP IDLE on the inbox and polls
-  the other folders; for each new, changed or removed message it publishes an event on its own stream `MAIL` —
-  account, folder, message id, date, from, to, subject, size, flags and attachment references, never a body or
-  an attachment's bytes (ADR 0359 §2). The stream keeps 7 days (`module.json`).
-- **A send's own record** lives in its state bucket `sends`, which only the `send` process and the tools write
-  (`module.json`; ADR 0436 §8).
-- **The index and the attachment store are its own.** A row per message and folder lives in its own Postgres
-  database; attachments live in an object-store bucket, each kept once by its SHA-256 digest (ADR 0359 §3, ADR
-  0439 §5-§6).
-- **Two more buckets answer without the database.** An account bucket holds each account's state and, per
-  folder, its name and its mail and unread counts; a mail bucket holds the newest mails of each account (up to
-  200, fewer once there are more than 81 accounts), for a view that need not ask the database (ADR 0439 §2-§4).
-  `mesh-mail-web`'s accounts page reads the folders from this bucket — a read wider than any one caller's grant
-  — but only for an account its own grant already let it ask about (ADR 0440 §4).
-
-## 3. `grants` — one list per account, giving both at once
-
-- **The setting.** `mesh-mail`'s trusted setting `grants` names, per account, the callers that may reach it: a
-  module's name alone (granted wherever it runs), `<machine>.<module>`, or a person. Nobody is granted an
-  account by default (ADR 0359 §4).
-- **One check, every door.** The code that decides whether a caller may read an account's mail (`mail_search`,
-  `mail_read`, the account's share of `MAIL`) and the code that decides whether it may ask to send from it
-  (`mail_send`) is the same function, reading the one list (`modules/mesh-mail/cmd/mesh-mail/config.go`'s
-  `Grants.Allows`, called from `tools.go` for every tool, `mail_send` included, confirmed on `origin/main` at `a67f0196`). There is no
-  second list and no narrower grant for sending alone: a caller named for an account may do both, and a caller
-  left out of it may do neither.
-- **Who is granted, today, for every account alike** (`mesh-controller.settings` for `mesh-mail`, read live on
-  2026-10-22): `mesh-mail-notifier` (named alone, so wherever it is assigned it may read); each of the four
-  machines' own `node-tools` — the control-node's, the laptop's, the workstation's and the home server's, which
-  is how an agent session on any of them reaches a mail account at all; the control-node's `mesh-mail-web`; and
-  the control-node's `mesh-mail-reader`. So the notifier, every machine's agent sessions, the web client and
-  the mail reader can each both read an account's mail and ask to send from it, from the one list — ADR 0472
-  §1 and §3 decided the mail reader joins this same list, rather than a narrower one of its own, and that it
-  simply never calls a send verb: its manifest invokes `seat:mail-store.read` and `seat:mail-store.accounts`
-  alone, no send verb of `mail-store` (`modules/mesh-mail-reader/module.json`, confirmed on `origin/main` at
-  `835bf22b`).
-
-## 4. The send path
-
-- **A send is an ask, never a write by the tool.** `mail_send` (account, to, subject, body) is open only to a
-  caller the account's `grants` names. It performs nothing itself: it raises an ask on the operator channel
-  naming the account, the recipients, the subject and the first lines, and returns the ask's id at once (ADR
-  0361 §2).
-- **The operator's Approve queues it once.** On an Approve recorded on a channel that proves who answered,
-  `mesh-mail`'s tools record the send `approved` and publish it, once, on the work queue `mail-sends`, carrying
-  only the send's id, its account and its ask id — never the recipients, subject or body, which stay in the
-  send's own record (ADR 0436 §8).
-- **A process of its own performs it.** `mesh-mail`'s process `send` runs as its own account, `mesh-mail-send`,
-  never the tool runner's account: it alone reads the accounts' passwords. It takes work from the queue,
-  verifies the operator's warrant again against the router's own record rather than trusting the queued message,
-  claims the send once, hands it to the account's outgoing server, and records the outcome — retrying a send the
-  server provably never took, up to five times, each after a longer wait, before giving up (ADR 0436 §2, §7,
-  §9-§10).
-- **`mail_send_status` answers one of a fixed set of states**: waiting for the operator, approved and waiting
-  for the sender, being sent, waiting for its next attempt, sent, failed (with its reason), refused, not proven
-  (the handover may or may not have reached the server), declined, expired, or unknown for an id it does not
-  know or that belongs to another caller's send (`send.go`, `sender.go`; ADR 0436 §12).
-
-## 5. `mesh-mail-web`
-
-- **Its pages**, all behind sign-in: the accounts page (`/`), a folder (`/folder`), search (`/search`), one
-  mail (`/mail`), an attachment download (`/attachment`), writing a mail (`/write`), its send (`/send`) and its
-  state (`/send-status`), a mail correction (`/mail-correct`) and a reading-lesson undo (`/mail-undo`) — plus
-  the sign-in callback (`/signed-in`). Every changing form (the send, a correction, an undo) carries a token
-  bound to the session (`server.go`, `csrf.go`).
-- **The accounts page now opens on mail reading, above the classical list** (ADR 0459 §13, issue
-  1430, 1523; `accounts.go`). It asks `mail-reading.status` first; not answering at all makes the whole
-  section say mail reading is unavailable and why, and nothing else here is asked — the classical list below
-  still renders regardless. Otherwise it shows, in order: the mail that matters (`mail-reading.entries`, mark
-  `matters`), each with a correction form (mark, mail group) that posts to `/mail-correct`; the mail groups
-  (`mail-reading.groups`) when mail reading is healthy, or the unhealthy cause and since when in their place
-  when it is not; the scam warnings (the same `entries` answer, mark `scam warning`), each with the same kind
-  of correction form, shown either way; the reading lessons (`mail-reading.lessons`, newest first), each with
-  its own undo form posting to `/mail-undo`; and the weekly reading-lessons-per-100-read-mails measure, from
-  `mail-reading.status`'s own answer. A mail body never reaches this section — only a mail entry's headers,
-  mail group, summary, mark, why and due date.
-- **A correction or an undo is asked of `mail-reading`, not acted on here.** `/mail-correct` and `/mail-undo`
-  are refused with no sign-in or a form token from another session, before `mail-reading.correct` or
-  `.undo` is ever asked; whatever `mail-reading` answers or refuses, the page is simply shown again, so a
-  refused correction is never surfaced as its own error (`mailwrite.go`, issue 1523).
-- **Sign-in is Keycloak's.** The module requires `oidc-client` and uses the authorisation-code flow with PKCE;
-  the identity (the ID token's own username claim) must be in the trusted setting `operators` — nobody by
-  default, and today one identity, the operator's own (ADR 0440 §3; `mesh-controller.settings` for
-  `mesh-mail-web`, read live on 2026-10-22). The session cookie is `Secure`, `HttpOnly` and `SameSite=Strict`,
-  ending 12 hours after sign-in (`auth.go`).
-- **Reachable only from the mesh's own machines.** Its route's reach is set to `internal`, so the route proxy
-  composes only its internal name, never a public one, and the module itself answers any other host 404 (ADR
-  0440 §2; `server.go`).
-- **A mail is shown as text.** `mail_read`'s own HTML-to-text is rendered through `html/template`'s escaping,
-  never parsed as markup; an attachment is answered only as a download, `Content-Disposition: attachment` and
-  `X-Content-Type-Options: nosniff`; every page carries a content security policy allowing nothing from
-  elsewhere (ADR 0440 §5; `mail.go`).
-- **It keeps no database of its own.** Nothing on disk beyond its own settings; it reaches mail only through
-  `mail-store`'s verbs, calling as `<machine>.mesh-mail-web`, and reads one thing directly besides —
-  `mesh-mail`'s account bucket, for folders and counts, of an account its own grant already let it ask about
-  (ADR 0440 §4, §6). Its manifest now also invokes `mail-reading`'s six verbs (ADR 0459 §13): it
-  reads `entries`, `groups`, `lessons` and `status`, and writes a correction or an undo with `correct` and
-  `undo` — writes that land in `mail-reading`'s own database, never in anything `mesh-mail-web` keeps itself.
-
-## 6. `mesh-mail-notifier`
-
-- **One notice per new inbox mail, at most once.** For each account it is granted, on hearing `mesh-mail`'s
-  `added` event, it shows the sender (name and address), the subject and the account's name through the
-  machine's `node-notifier`, under its own account (`runs-as`), never the tool runner's.
-- **Quiet rules.** It shows nothing for a mail outside the inbox, for a mail from the account's own address, and
-  for a mail already flagged read when it arrives (`notifier.go`, `mailevent.go`). During an account's first sync
-  or a resync `mesh-mail` publishes no `added` events, so nothing reaches the notifier then (`notifier.go`'s
-  opening note, citing `mesh-mail`'s `imap.go`).
-- **Folding.** More than three qualifying mails of one account within a trailing 60-second window become one
-  notice, shown once the window has passed since the fold's own first mail, naming how many and the latest
-  sender; a message already shown — tracked by its message id, or by its folder, UIDVALIDITY and UID where it
-  has none — is never shown twice, even redelivered. A notice that fails to send is retried at most once a
-  minute (`notifier.go`, its constants `FoldOver`, `Window`, `RetryBackoff`).
-- **Assignment.** It is assigned today to the laptop and the workstation (live read, 2026-10-22; `mesh_machine`
-  for each shows its seat `mail-notifier` and tool `mail_notifier_health` there, and neither on the
-  home server or the control-node), where it needs `node-notifier` to be held beneath it. ADR 0461 §7 names
-  these same two machines as the ones it is to be unassigned from, on the operator's Approve, once mail
-  signals (§8) are proven live on the operator's real accounts (issue 1418) — as built, that unassignment has
-  not happened.
-
-## 7. Health
-
-- **`mesh-mail`**'s liveness is its `keep` process's own unit health; its watching is judged once a minute by
-  its `watch` process and read through the tool `mail_health`: `waits` (naming the secret) for an account whose
-  password was never given, `unhealthy` (naming the account and why) for a connection down or an IDLE silent
-  for five minutes, healthy otherwise; its `send` process is a plain unit (ADR 0359 §6; `health.go`).
-- **`mesh-mail-web`**'s own tool `mail_web_health` reads the one state its HTTP endpoint keeps: still setting up
-  sign-in, listening, or ended with its error — unhealthy whenever it is not listening (`main.go`).
-- **`mesh-mail-notifier`** declares no process resource: its manifest declares only its account and its state
-  directory. Its bundle is the one process the machine's runtime launches for it and keeps alive, under its own
-  account (`runs-as`); it serves its tools and runs the watcher beside them (`main.go`'s opening note; commit
-  12d78520, issue 859). Its tool `mail_notifier_health` is unhealthy once an account's notice
-  has failed to show for more than ten minutes, and answers only when asked; no check of the node-engine judges
-  the module by it. A watching process of its own is tracked by issue 841, not yet decided (its `README.md`).
-  The comment in its `health.go` that still names a process `notify` predates that commit. It keeps one state
-  bucket, `shown`, for 30 days, to show no mail twice (`module.json`).
-
-## 8. `mesh-mail-reader`
-
-- **It claims `mail-reading`**, the fourth mail seat, held once for the mesh, serving six verbs:
-  `entries`, `groups`, `correct`, `lessons`, `undo` and `status` (ADR 0459 §1, §2; `module.json`,
-  `tools.go`). Each answers only a caller the trusted setting `callers` names — a bare module name, granted
-  on any machine, `<machine>.<module>`, or `person.<name>`, the same shapes `mesh-mail`'s own `grants`
-  matches, copied in miniature so this module never imports `mesh-mail`'s code (`callers.go`). The setting
-  defaults to `["mesh-mail-web"]` and is unchanged on the live mesh (`mesh-controller.settings` for
-  `mesh-mail-reader`, read live on 2026-10-22), so only `mesh-mail-web` may call a `mail-reading` verb today;
-  any other caller is refused, naming why.
-- **Its own account and database.** It runs as its own account, `mesh-mail-reader` (`runs-as`), never the
-  tool runner's, because it hears `mesh-mail`'s restricted stream `MAIL` under it. It is granted reading on
-  every account `mesh-mail` holds — named as the control-node's `mesh-mail-reader` in `mesh-mail`'s `grants`
-  for each of the three accounts alike (`mesh-controller.settings` for `mesh-mail`, read live on 2026-10-22) —
-  and never asks to send: its manifest invokes `seat:mail-store.read` and `seat:mail-store.accounts` only, no
-  send verb, and its code calls neither `mail_send` nor anything that moves, flags or deletes a mail (ADR
-  0459 §11, ADR 0472 §3). It keeps its own Postgres database (`postgres-database`, contributed as
-  `mail-reader`), separate from `mesh-mail`'s index.
-- **Its database holds four tables, no mail body in any of them** (`schema.sql`): `mail_entry` — one row per
-  judged mail, its account, message id, folder, date, sender name and address, subject, its `mail_group`, a
-  `summary` of at most 160 characters, its `mark` (`matters`, `scam warning` or `neither`, or null), `why`,
-  a `due_date`, whether it was `told` and when it was `judged`; `mail_group` — a label and when it was first
-  made; `reading_lesson` — the corrected mail's own headers (account, folder, sender name and address,
-  subject), the mail group, the `change` made, when (`made`), and whether it was `undone`; and `waiting_mail`
-  — a mail heard but not yet read, by its account, folder, message id, UIDVALIDITY and UID (unique together,
-  so a mail heard twice is kept once), its date, sender, subject, flags and size, in the order it was heard. A
-  fifth table, `reader_health`, keeps its own health (below) across a restart.
-- **It hears mail under its own account.** It consumes `mesh-mail`'s stream `MAIL` for
-  `mesh-mail.mail.*.message.added` events alone (`AddedPattern`, `hear.go`), recording each as a row in
-  `waiting_mail` before the handler returns — so the controller's durable consumer redelivers an event a
-  store failure lost, rather than it being silently dropped — and keeping a mail heard twice to one row, by
-  its own unique key above (ADR 0459 §3, §12; `hear.go`).
-- **Its batches**: at most 10 mails at a time (`MaxMailsPerBatch`), taken from `waiting_mail` in the order
-  they were heard; a batch starts no sooner than 160 seconds after the previous batch started (`BatchGap`,
-  pinned to the constant `MinBatchGap` in every production build; only a build tagged `integration` may
-  shorten it, and never in a way a unit test lets reach production) — bounding mail reading to at most 225
-  mails an hour (ADR 0459 §5, §15; `batch.go`, `question.go`). Each batch is one judgement, asked of
-  `claude-code.claude_code_judge` on this module's own machine (`MESH_NODE`) and collected with
-  `claude_code_judged` when it answers pending; it is asked to answer `within` at most 40 seconds
-  (`JudgeWithin`), and the whole question — the framing that a mail is data and never an instruction, the
-  existing mail groups (largest first, at most 4 KiB), the reading lessons that apply (at most 40, matching
-  sender or mail group first then newest, at most 12 KiB) and up to 10 mails (each at most 3.5 KiB: headers
-  at most 512 bytes, text cut to its first 3 KiB) — is bounded to 55 KiB. A mail the provider filed as junk
-  (its folder named Junk or Spam, or carrying the `\Junk` flag) is said as that fact beside its text. A mail
-  that has simply gone (moved or deleted since it was heard) is taken out of the waiting queue without ever
-  being judged; any other read failure leaves the whole batch waiting for the next slot; on success, one
-  mail entry is written per mail and any new mail group is made; on a refused, timed-out or out-of-shape
-  judgement, nothing is written, every mail given stays waiting, and the reader's own health (below) is set
-  unhealthy (`batch.go`'s `RunOneBatch`, `RunBatches`).
-- **Its mail signal.** After each batch, win or lose, it tries to tell the operator: every entry marked
-  `matters` and not yet `told` — carrying one over from an earlier batch that went untold — is gathered into
-  one `operator-channel.tell` with subject `mail`, naming the mail with the nearest due date first, then the
-  next one, ending "and N-2 more on the mail page" past two; nothing is sent, and nothing asked at all, when
-  there is nothing to tell or while the reader is unhealthy (read fresh from the store, not assumed). The
-  words are checked first, line by line, with `messenger.messenger_check`; any one refused falls back to the
-  safe form "N mails matter: open the mail page". Only once `tell` answers that some channel actually sent it
-  are those entries marked `told` (ADR 0461 §1-§6; `tell.go`, `signal.go`).
-- **Its health**, `mail_reader_health`, is asked by the node-engine itself (`runtime-health` of kind `tool`,
-  every 60 seconds) and carries no caller check. It is unhealthy once a batch judgement is refused, times
-  out, or answers out of shape, naming which of the three, the judgement's own words, and since the first
-  such failure in a row (a later one in the same run never pushes that time forward); healthy again once a
-  judgement succeeds. The state survives a restart, kept in its own database rather than only in memory (ADR
-  0459 §12; `health.go`).
-- **What it never does.** It changes no mail: it moves, flags, deletes and sends nothing, asking no verb of
-  `mail-store` that would (ADR 0459 §11). It keeps no mail body and no text taken from one — only headers, a
-  summary at most 160 characters, a mark, why, and a due date (ADR 0459 §4).

-  more once it loses its lease (ADR 0550 §2).
-- **Licence grants and tokens.** The refresh tokens, the API key and the access tokens of every licence are vault

-  it holds no value for (the controller's own, the node and device accounts, the module and process accounts its

-  never touches a key that holds the hash of its own value, and writes an adopted key again when the loaded list
-  carries another hash for that user. Its tool `secret_own` lists the adopted users and each adoption, and
-  `account_adopt` adopts now (ADR 0550 §4).
-- **Module secrets** stay as the sections below describe them: a module's own secrets, the credentials between a

-**Changed 2026-10-22** (ADR 0507, ADR 0508, ADR 0510; milestone issues 1840 and 1841). `pacman` gains a
-process of its own on every node, the keeper, under an account of its own and a bus account of its own. It keeps
-the node's installed packages and what an upgrade would change in the module's states, written only on change
-(at its start, when the package manager's lock is released, when the mirror list is rewritten, and once a day),
-and says each change as an event; the controller keeps the packages each node's modules declare, so the view
-answers every node, one that is off included, and names the packages no module declares. Upgrades are runs on
-the bus. The weekly timer of ADR 0477 §5, which upgraded every node at the same moment, is dropped. Instead the
-nodes upgrade one at a time, in the order of the mesh-level key `upgrade-order`, each after the node before it
-passed its after-upgrade check. With no order set no round starts, and every node's health says why. Before each
-run a package record is taken and read back. A kernel that an installed DKMS module's own bound excludes is held
-with its headers, and said. After each run the after-upgrade check names left configuration files, the
-distribution's news, newly failed units, a restart needed, processes still mapping a replaced file and DKMS
-modules not built for an installed kernel. A rollback returns a node to a record and says first what it would
-change. Only the operator passes a node that stopped a round. The keeper never runs as root: the few acts that
-need root go through a root-owned helper process with a closed list of verbs, on a socket only the keeper's
-account opens (ADR 0510). The module's health is read from the bus, not from a unit's age.
-
-`kernel` gains the fallback kernel: `linux-lts` and its headers on every machine, with its boot entry on
-whichever loader the machine boots with, read from the machine (systemd-boot or GRUB), the default entry left
-untouched (ADR 0508 §9-§10, changing ADR 0381 §4). A hook found on a machine that copies every kernel image to
-one fixed boot name is taken over: moved into the module's state and named, since it would put the fallback
-kernel in the default entry's place. *How it is checked:* the modules' unit tests (the root helper refuses every
-verb and argument off its list and every account but the keeper's; the round starts a node only after the one
-before it passed; the boot-entry script in stand-in trees of both loaders), an integration test that runs the
-keepers of two made-up nodes on a real bus, and, after the delivery, the view answering every node and every
-boot menu listing the fallback kernel.

-milestone (ADR 0493 §2) is checked inside that issue's one write, refused naming the milestone it is in; a link to a
-milestone that does not exist or is closed is refused (§3: a fix found on the way joins the open milestone). A milestone's
-issues are read from the issues in memory. Pull requests and commits are linked to the issue they fix the same way, with
-the kinds `pull-request` and `commit` (§4); nothing reads them from a description, and the triage never adds one.
-
-**The seed** is `import` with `milestones` and a design's number: it reads the table through the records module, makes
-each record that is absent in the table's order, links each issue it names that has no milestone, refuses (and names)
-an issue another milestone holds or two rows name, closes a milestone whose issues are all done (wontfix, or resolved
-with every live fix delivered, or resolved with no live fix) when it refused none of its row's issues, and run again
-changes nothing. Once a design is seeded, the tracker is the only list of its milestones'

-stay in this repository as files: they are how work is done here, not records of what was decided (research 061).
-
-### 9.1 Designs and glossary entries as records
-
-**A design** is a record of the kind `design`, named "design NN" and keeping its number (ADR 0423). Its text is its
-sections: the `to-be` section, what is being built, and the `as-is` section, what runs. Each of the as-is documents
-becomes the as-is section of the design it describes, never a record of its own: the import matches 3 of the 18 by
-name and 15 by topic, and shows the operator the list before it runs. Its owning repositories are its field `code`;
-its decisions, and every design it names, are `cites` links. It holds no state written by anyone (§ 9.2). A new
-design takes its number from `reserve` and is written with `propose`, and is reviewed as every record is (§ 5).
-
-**A glossary entry** is a record of the kind `glossary entry`, one per entry of the glossary page, kept whole: its
-head word or words (an entry may name several with one meaning, as research effort, graduation, hand-off and playbook
-do), its domain, its meaning, its *Not:* line with each retired word's scope, and its identifier line. Each row of
-the page's homonym table becomes an entry of its own, naming the qualified form each domain uses. The entries replace
-the page as the authority on words (ADR 0423, changing ADR 0244).
-
-**The readers change with them.** Everything that read the page or the design folders reads the records instead:
-
-| Reader | Reads, after the move |
-|---|---|
-| the knowledge base's own rule on a retired word (§ 4) | the *Not:* and identifier lines of the entries, no longer the page through the records module; it judges a design when it is proposed, as it judges a decision |
-| hq's word check | the entries' *Not:* and identifier lines, and its uniqueness check (a head word heading two entries, or also retired) over the entries; it covers what stays in this repository, and designs leave its coverage |
-| the catalogue's repository check | the retired words of no scope or *(tools)* from the entries; its copied list is retired, so hq has no copy to compare |
-| hq's cycle check | the design records, for every design naming its decisions, not files under `03-DESIGN/` |
-
-Each of the four fails, saying so, when the knowledge base does not answer, and never passes on nothing.
-
-**Links become links between records, and the old paths go.** At the import every file link inside a design becomes
-a link between records, which the rule on a link to nothing then checks (§ 4). The links from documents that stay in
-this repository are rewritten to name the design ("design 47"). No page stays at an old path: afterwards this
-repository holds no file under `03-DESIGN/` and no `00-META/glossary.md`.
-
-**It moves in one delivery**, as the records did: the import, the two kinds, the four readers, the rewritten links,
-the playbooks' steps that write a design, and the instruction text sessions read, which names the glossary's place.
-A reader left behind would pass on nothing, so none moves alone.
-
-### 9.2 A design's state
-
-**The knowledge base says a design's state, and nobody writes it** (ADR 0424): proposed, designed, in progress or
-implemented, kept matching what runs. No person, session or document sets it, and `propose` refuses a design that
-carries one.
-
-It reads two things. The issues are those the issue tracker holds with a `design` link to the design. Whether one
-is done comes from its deliveries: an issue is done when it is resolved and the delivery its fix went out in reached
-`delivered`, whether a hotfix alone or a delivery group. The delivery module announces each delivery done on the
-bus, and on each announcement the knowledge base works the state of every design that issue links out again.
-
-```

-| a decision the design names is not accepted | proposed |
-| no linked issue done, or no linked issue at all | designed |
-| some linked issues done | in progress |
-| every linked issue done | implemented |
-
-Three kinds of issue count apart: an issue closed won't fix is left out; an issue resolved with nothing to deliver,
-a fix of documents only, is done when resolved; and a new issue linked to an implemented design makes it in progress
-again, until that issue is done. Milestones are not read: a milestone is a group of a design's issues delivered
-together, and the state depends only on the issues and their deliveries.
-
-**Imported designs say what they lack.** A design imported with no linked issue shows `no issues linked yet` beside
-designed, until an issue is linked to it; the import names each such design by number. Linking their issues is
-tracked by issue 428.
-
-### 9.3 Its place beside design 47
-
-The delivery-done announcement this slice reads is design 47's
-([47 — Delivery](47-delivery-from-commit-to-delivered.md)): its hotfixes and delivery groups, and each delivery's

-### 5.1 An identity on the machines (ADR 0411, ADR 0414)
-
-A person or agent identity also holds a **login name**, the **machines** it is present on and, for a person, the
-login name kept on a machine where it differs. The seat starts with two: the operator's person identity and `nox`, the one
-agent; every piece of agent work is a thread of `nox` (§2), and a second agent identity is made only when a rule needs
-another role. The agent is `nox` everywhere: its login, its forge account (the forge account `nox-agent` renamed,
-keys and team kept), Keycloak, mail and the bus. A login or service account the mesh makes for the operator from now on carries the operator's identity name;
-the operator's existing logins and forge account are kept as they are. On a machine where agents ran as the
-operator's login, that login stays the operator's and `nox` gets a login of its own; nox's bus account is `agent.nox`. `nox` is also the
-operator's terminal command (`mesh-cli`), and prose says which is meant.
-
-An identity's login on one machine is its **machine account**. The controller composes the machine account of every
-identity present on a machine into that machine's declaration, and the node-engine applies it with its `user`
-resource. A login that exists is adopted under its name, uid and home; the mesh never renames or deletes one. An
-agent's machine account has its own home and group, no password, no root group and no sudo rule, and the node-engine
-judges on every look that it cannot become root without a person, by the ways ADR 0266 §12 to §17 list. No module declares a login for a
-person or an agent: claude-code's `agent-account` resource goes, and the catalogue's check refuses a manifest that
-declares one. The node record's operator account and agent account are read from the identities, no longer stated
-at the controller's terminal or in the mesh-config snapshot; the machine facts `account`, `agent-account` and their
-homes keep their names. A machine names an agent account only where the identity seat marks an agent as its agent
-account: the control node, marked `nox`, where the guard and the licence stay as they are. The other machines are
-marked with none, so the guard stays off there and the operator's sessions keep the mesh's tools, while the login `nox` serves the
-modules run for `nox`. Where a person or an agent is present, its kept logins and the agent account mark change only
-through a verb of the identity seat that only the operator calls, on an Approve; an assignment never sets the mark,
-because an agent may call the verb that changes an assignment (ADR 0266 §4). The verb, and the controller at composition,
-refuse an agent whose login on a machine would be `root`, a person's login there or a well-known service account
-(ADR 0266 §5). The self-check judges every agent login,
-marked or not. The seed: the operator on every machine, with the operator's existing login kept where it differs from the
-identity's name; `nox` on every machine, the agent account on the control node.

-
-### 5.2 Run for an identity (ADR 0412)
-
-Every module runs as the operator account of its machine, as today, with no setting; running for the operator is that
-default run. A manifest may declare that its module can **run for** an agent identity, at assignment, at start or both: serve one identity with that identity's machine account, home and bus password.
-An assignment of such a module may name the identity it runs for, and the module may let the one who starts it
-choose: claude-code started for the operator is the default run with the operator's configuration, and started for `nox`
-it runs for `nox` with the agent's home. A start
-goes down only: a module is started for an identity by a process already running as that identity's login, or by the
-operator's own login for an agent; an agent never starts one for a person, and the module refuses it, naming who asked
-and for whom. A module may be assigned to one machine once per identity it runs for there, each its own process under
-its own login, and the controller keys an assignment by machine, module and identity. The first two to declare it are
-claude-code and ssh-client. On a machine the identity seat marks with an agent account, claude-code's assignment is
-run for that agent (`nox` on the control node), so its licence and home scope stay in the agent's home, and the controller refuses
-one there that is not. ssh-client keeps its default assignment for
-the operator wherever `nox` is present and gains a second one run for `nox`, which makes the agent's forge key in the
-agent's home and closes issue 989; gitea's provider registers that key on the forge account `nox`. A module run for an identity calls as that
-identity and gets no module identity of its own (this narrows ADR 0386 §4, which holds for every other assignment). A module with an account of its
-own (`runs-as`, ADR 0259 §8) cannot declare it, and a run for an identity with no machine account on that machine is
-refused at composition and at start. ADR 0266's guard
-stands: on the control node, a session started for the operator gets the operator's configuration and its tool calls are still
-refused.
-
-### 5.3 A bus password per identity (ADR 0413)
-
-Each person and agent identity has a bus account of its own (`person.<name>` for the operator, `agent.nox`), whose memberships are made
-from its role, and its password is a secret owned by its machine account at mode 0600 on each machine it is present
-on, which no other account but root can read. A person's password is placed only on a machine that names an agent
-account of its own judged unable to become root, by a verdict at most fifteen minutes old; on the other machines, where agents can still run as the operator,
-it is not placed, and the controller says so. A module run for an identity reaches the bus with that password, can do
-only what the identity's role allows, and every call is recorded as that identity's. Nox's role never holds an approval
-grant, a trusted party's grant or a dangerous tool named in it (ADR 0387 §4 does not apply to it), and the identity seat
-refuses one; each dangerous act of nox's is asked one by one. The break-glass agent (§6) keeps its own rules and gets
-no login and no bus password from this. This changes ADR 0259 §8, which kept every bus credential out of an agent's account; the rest of §8 stands.
-The password lives in today's list of bus accounts and is replaced by a signed login for the same role at the bus
-switch (§7, §8).

-   the operator's existing logins are
-   unchanged.
-8. No manifest in the catalogue declares a login for a person or an agent; the catalogue's check refuses one.
-9. For every machine, the declaration before and after differs, for the modules not set to run for an identity, only
-   in the machine accounts' `user` resources (now the controller's, and `nox` added on the other machines); claude-code on the control node, run for `nox`, places the same
-   files in the same home; on the other machines the guard stays off and the operator's sessions keep the mesh's tools.
-10. A session started for `nox` on the control node gets the agent's home configuration and one started for the operator the
-    operator's, with no tool call through; a session as `nox` that starts claude-code for the operator is refused; with
-    ssh-client run for `nox`, nox's key is on the forge account `nox` and the session pushes a branch over SSH as `nox`.
-11. Nox's bus password is owned by `nox` at mode 0600 on every machine nox is present on; a call with it outside
-    nox's role is refused; a grant test finds no approval grant, trusted party's grant or dangerous tool in nox's
-    role; the operator's password is placed only on a machine with an agent account judged root-free within fifteen
-    minutes, and the controller says so for every other.
-12. The forge account `nox-agent` is renamed `nox`, keeps every machine's key, stays in the agents' write team, and
-    every `forge-account` entry names `nox`.

-# 59 — The mail web client
-
-**The operator's mail, every account of it, in a browser on the mesh's own machines. A module of its own,
-`mesh-mail-web`, holds the seat `mail-webclient`; it renders pages on the server in Go and reaches mail only through
-`mail-store`'s verbs, under a caller the operator grants account by account. Its route reaches the private network
-only, under its internal name, and the operator signs in with Keycloak. A mail written there goes out only on the
-operator's Approve, as every mail the mesh sends does.**
-(ADR 0440, building on ADR 0378 §5 and ADR 0379 §2.)
-
-**Then the model reads the mail for the operator.** A module of its own, `mesh-mail-reader`, holds the seat
-`mail-reading`: it reads each new mail in batches, keeps a mail entry for it (its mail group, one line, its mark),
-tells the operator on Telegram of the mail that matters in a mail signal, shows a scam warning on the page only, and
-learns from the operator's corrections as reading lessons; it never changes the mailbox and keeps no mail text.
-The pop-up for every new mail retires once mail signals
-work. Later, once the mesh's threads exist, the operator asks questions about their mail in a mail conversation, a
-thread with a mail context. Betterbird is removed once mail reading works on the laptop and the workstation.
-(Research 066; ADR 0458 to 0462. The words are the glossary's Mail domain.)
-
-**Acceptance.** In a browser on the laptop and on the workstation, the operator signs in, browses, searches and reads the mail of
-every account `mesh-mail` holds, opens an attachment, and writes a mail that goes out on their Approve on Telegram;
-the same page is not reachable from a machine outside the private network. A new mail that matters reaches the
-operator's phone as one mail signal and stands at the top of the mail page in its mail group; a mail that does not
-matter gives no pop-up and no mail signal anywhere.

-                                         mesh-mail's account bucket (ADR 0439 §2): folders and their counts
-```
-
-- **`mesh-mail-web`** is built from `mesh-mail`'s source, as `mesh-mail-notifier` is, and is assigned to the machine
-  that runs `mesh-mail` (the control-node today). It keeps no mail: no database, nothing on disk (ADR 0440 §1, §4).
-- **`mesh-mail`** gains its account bucket (ADR 0439 §2, issue 1255) and a caller check on `mail_send_status`
-  (ADR 0440 §7, issue 1261), both released with `mesh-mail-web`. It
-  answers `mesh-mail-web` only for the accounts its trusted setting `grants` gives `mesh-mail-web` (ADR 0359 §4,
-  ADR 0378 §13). `mail_send_status` becomes part of `mail-store`'s protocol (ADR 0440 §7).
-- **The browser never reaches the bus.** The bus has no WebSocket listener or sign-in for a person yet (research 036,
-  gap G1), so every page is HTML from `mesh-mail-web` (ADR 0440 §5).
-
-## 2. Reachable from the private network only (ADR 0440 §2)
-
-The operator's rule of 2026-10-15: a web UI for mail is reached only over the mesh's private network, never from
-outside. Two things hold it:
-
-1. **Its route's reach is `internal`** (ADR 0138 §7). Reach is a setting of the machine a module runs on, keyed by
-   port, and with none the route proxy composes a public name as well as the internal one. So `mesh-mail-web`'s
-   `reach` is set to `internal` on its machine before it is assigned there. The route proxy then composes only
-   `mail.<node>.internal`, serves it only to the mesh's own machines (ADR 0167 §6), and certifies it with the mesh's
-   own authority.
-2. **The module answers only its internal name.** A request whose host is not `mail.<node>.internal` is answered
-   404, so a public name composed by mistake shows nothing.
-
-Measured on 2026-10-19: the laptop and the workstation hold the mesh's authority (`mesh-internal-ca.crt`) as a trust anchor, and
-Firefox on both reads the system's trust through p11-kit, so the page opens there without a warning. Away from the
-private network (the laptop travelling without its tunnel) the page is unreachable; Betterbird stays the offline client
-until it is removed (milestone 3, §11).
-
-## 3. Signing in (ADR 0440 §3)
-
-`mesh-mail-web` requires `oidc-client` from Keycloak, as grafana does, and uses the authorisation-code flow. It answers
-no page, attachment or send to a browser that has not signed in, and lets in only the identities its trusted setting
-`operators` names (nobody by default). The session cookie is `Secure`, `HttpOnly` and `SameSite=Strict` and ends
-after 12 hours. Every form that changes something (today only the send) carries a token bound to the session.
-
-The operator chose this on 2026-10-19: without it, any process on any mesh machine, agents included, could read every
-account through the page and get around `grants`.
-
-## 4. The pages
-
-| page | what it shows | how |
-|---|---|---|
-| accounts | every granted account, its state, its folders and their counts | `mail_accounts`; the folders from `mesh-mail`'s account bucket, only of an account `mail_accounts` answered (the bucket's read is wider than the grant, ADR 0440 §4) |
-| folder | one folder's mails, newest first, in pages of 50 | `mail_search` with the folder; the next page asks for mails before the last one shown |
-| search | mails across every granted account by words, sender, recipient, date, attachment | `mail_search`'s filters (issues 1228-1232) |
-| mail | one mail: its headers, its body as escaped text, its attachments | `mail_read` |
-| attachment | one attachment, as a download | `mail_read` with the attachment's key |
-| write | from (a granted account), to, subject, body; after sending, the Approve's state | `mail_send`, then `mail_send_status` |
-
-- **A mail is shown as text** (ADR 0440 §5): `mail_read` turns HTML into text, the page escapes it, and nothing
-  remote is loaded. An attachment answers `Content-Disposition: attachment` and `X-Content-Type-Options: nosniff`.
-  Every page carries a content security policy that allows no script or style from elsewhere.
-- **A send is an ask** (ADR 0361 §2): the page says the ask is raised, then follows `mail_send_status` (ADR 0436
-  §12's states, now part of `mail-store`'s protocol, ADR 0440 §7) until a final one: sent, failed, refused, not
-  proven, declined, expired or unknown. The operator's Approve comes on Telegram, as for every mail the mesh sends.
-- **The seat's verbs** (ADR 0378 §5): `open` answers the page's address, and with an account and a mail that mail's
-  page; `status` answers whether it serves and which accounts it is granted.
-
-## 5. One list per account, reading and asking to send alike (ADR 0472)
-
-`mesh-mail`'s trusted setting `grants` stays one list of callers per account, giving both reading (that account's
-`MAIL` events, `mail_accounts`, `mail_search`, `mail_read`) and asking to send (`mail_send`, `mail_send_status`):
-the operator's Approve on every send is the guard (ADR 0472 §1, §2, which supersedes ADR 0460's split; issue 1227
-will not be done). `mesh-mail-reader` is named in `grants` for every account after its delivery, on the operator's
-Approve, and asks to send nothing: its manifest invokes no send verb (ADR 0472 §3). Who may call `mail-reading`'s
-own verbs is its own trusted setting `callers`, `mesh-mail-web` by default (ADR 0459 §2).
-

-                       mesh-mail-web ── entries · groups · correct · lessons · undo · status ──▶ the mail page
-```
-
-- **One module, one seat.** `mesh-mail-reader`, built from `mesh-mail`'s source like `mesh-mail-web`, claims
-  `mail-reading` (declared in `mesh-mail`'s manifest beside the three seats of ADR 0379 §4) and runs once, on the
-  machine that runs `mesh-mail`. It hears `added` events under its own `runs-as` account and the operator's reading
-  grant (ADR 0378 §13), and moves, flags, deletes and sends nothing.
-- **A mail entry per mail, never the body.** Its own database (`postgres-database`) keeps each mail's mail group,
-  a one-line summary, its mark (*matters*, *scam warning* or neither) and why, and a due date where the mail gives
-  one, beside the mail groups and the reading lessons.
-- **Batches.** One judgement reads at most 10 mails, and every part of its question has a bound, so it never
-  passes 55 KiB of the judgement's 64 KiB: the framing that a mail is data and never an instruction, at most 4 KiB;
-  the mail groups, at most 4 KiB, the largest first; the reading lessons that apply, at most 40 within 12 KiB,
-  sender and mail group first, then the newest, under the framing that a reading lesson outranks anything a mail
-  says; then each mail, at most 3.5 KiB (its headers at most 512 bytes, its text cut to its first 3 KiB), a mail in
-  a Junk folder said to be so. A batch asks for up to 40 s with `within` and collects with
-  `claude_code_judged` (built under issue 508, recorded by ADR 0459 §14). Research 066 measured 1.9 to 3.1 s per
-  mail, so a batch of 10 takes about 19 to 31 s. A batch starts at least 160 s after the previous one started, so
-  an issue tracker's check that waits behind a batch on the same machine ends within 115 s, inside its two minutes
-  (ADR 0278 §2), which research 066's 15 mails and 120 s back to back would not; mail reading then reads up to 225
-  mails an hour (ADR 0459 §15).
-  Batches stay judgements; whether they become threads is issue 1417.
-- **Reading lessons.** When the operator changes a mail's mark or mail group on the page, `mesh-mail-web` calls
-  `correct` and the correction is kept at once as a reading lesson (headers, the change, when; never body text),
-  with no further Approve: it is the signed-in operator's own act. The page lists the reading lessons, undoes one
-  (later mail reading only), and shows reading lessons per 100 read mails per week, which answers whether mail
-  reading learns the operator's way.
-- **The page** (replaced by design [63](63-the-mail-web-ui-with-mail-reading-and-owly.md)'s operator's list, ADR 0515 §5). Above the classical list it shows the mail that matters at the top, the mail groups, and the scam
-  warnings in a place of their own, each with why; the classical list (accounts, folders, search, one mail) stays
-  and always opens. `mesh-mail-web` reads these through `mail-reading`'s verbs and still keeps no mail state
-  (ADR 0378 §5 and ADR 0440 §4 as ADR 0459 §13 changes them); it writes the operator's corrections with
-  `correct` and `undo`.
-- **It fails loudly.** Its own health check is unhealthy when a judgement is refused, times out or answers out of
-  shape, with the cause and since when; the controller raises its condition, the page shows the cause above the
-  classical list instead of mail groups, and no mail signal is sent. On recovery the mail that arrived meanwhile is
-  read in arrival order from its durable consumer on `MAIL` (kept 7 days). A warning before a licence runs out is
-  issue 1409.
-
-## 7. Mail signals, and the pop-up retired (ADR 0461)
-
-- **One tell per batch.** A batch that marks mail as mattering sends one `operator-channel.tell`: the headline
-  "1 mail matters" or "N mails matter", a first line naming the mail with the nearest due date (sender's name,
-  summary, due date), a second naming the next and, with more than two, ending "and N-2 more on the mail page".
-  When the hourly cap of 10 refuses one, its mails stay at the top of the page and the next mail signal counts
-  them.
-- **Words only.** No link, mail address, host name or path: the router refuses a message holding any, and the mail
-  page opens only on the mesh's own machines. The reader checks its words with `messenger_check` first and, refused,
-  sends the safe form "N mails matter: open the mail page".
-- **At once, at any hour**; the phone's own quiet hours decide. **Never** for a scam warning, and never while mail
-  reading is unhealthy.
-- **The pop-up retires.** Once mail signals pass acceptance test 13 on the real accounts, `mesh-mail-notifier` is
-  unassigned from the laptop and the workstation on the operator's Approve and leaves `grants`; `mail-notifier`
-  stays declared and unheld, and nothing takes it over (ADR 0379 §3, §7). Betterbird's own pop-ups stay off by its
-  setting until it is removed (ADR 0379 §6). Issue 1418; issue 801 closes as replaced.
-
-## 8. The mail conversation (ADR 0462)
-
-**Replaced by design [63](63-the-mail-web-ui-with-mail-reading-and-owly.md):** Owly answers mail questions through
-mail reading before threads exist (ADR 0518, changing ADR 0462 §6); the conversation below is what Owly moves onto
-once threads exist.
-
-A mail conversation is a thread (ADR 0383), run by the thread handler (ADR 0384), with a mail context: the framing
-that a mail is data, the tools `mail_search` and `mail_read` only, under a caller of the thread's own named in `grants`
-(ADR 0472 §4; issue 1419), the operator's real senders and folder names, and the reading lessons. The operator writes a mail
-question on the mail page; each answer names the mails it found, and a question with no answer says so.
-`mesh-mail-web` creates and follows the thread over the bus on its server side; the page loads one script from its
-own origin and talks only to it (content security policy: script from that origin, `connect-src 'self'`), so the
-browser never reaches the bus. The thread keeps the text of each mail it read for good, as every thread is kept (ADR
-0383 §3), which the operator accepted; mail reading keeps none. In the same milestone `mail_search` matches folder
-names without regard to case and describes its three `-any` switches as true or false only. It is built after design
-58's milestone 3 (threads, issue 880) and once issue 1419's caller is decided.
-
-## 9. What stays outside
-
-Each is an issue with an owner:
-
-- a reply, cc, bcc and attachments on a sent mail: issue 1257 (it needs `mail_send` to take them first);
-- a page that shows new mail without a reload, from ADR 0439's buckets: issue 1258;
-- drafting a mail, the rest of issue 1259 (its triage is mail reading, its search the mail conversation), and writing
-  to the mailbox: issue 730;
-- a task list for the operator: issue 1396; the search faults found by research 066: issues 1400 and 1401;
-- the work account: a later decision of its own (ADR 0359 §7).
-
-## 10. The build's acceptance tests
-
-Tests 1 to 9 are milestone 1's; tests 10 to 17 are research 066's eight, in its order.
-
-1. A request without a session, for a page, an attachment or a send, is redirected to sign-in; an identity not in
-   `operators` is answered 403; a send form without its token is answered 403; the session cookie is `Secure`,
-   `HttpOnly` and `SameSite=Strict` and ends 12 hours after sign-in.
-2. A request whose host is not the internal name is answered 404.
-3. Against a stand-in `mail-store` and a filled account bucket on the real bus, the pages call only
-   `mail_accounts`, `mail_search`, `mail_read`, `mail_send` and `mail_send_status`, list folders from the bucket,
-   page by date, and a send shows its state; the manifest declares no database and no writable directory.
-4. A mail whose body holds `<script>` and a remote image is shown as text; an attachment is a download with
-   `nosniff`; every page carries a content security policy allowing only its own origin.
-5. After a mail is indexed, `mesh-mail`'s account bucket changes only the keys that describe it, within ADR 0439's
-   bounds (issue 1255's own tests).
-6. The declaration for its machine composes `mesh-mail-web`'s route with its internal name only (`mesh-controller.plan`).
-7. `mail_send_status` answers each state of ADR 0436 §12, and `unknown` for an id it does not know and for another
-   caller's send (a unit test of `mesh-mail`, issue 1261).
-8. The seat's verbs: `open` answers the page's address, and with an account and a mail that mail's page; `status`
-   answers whether it serves and the accounts it is granted (a unit test of `mesh-mail-web`, issue 1262).
-9. The acceptance sentence at the top, live: in a browser on the laptop and on the workstation, for every account.
-
-10. A new mail on each account has a mail entry, in a mail group, within 5 minutes of its mail event; a test searches
-    `mesh-mail-reader`'s database for a known body line and finds none.
-11. The reader asks no `mail_send` for any account, and no mail is moved, flagged or deleted by it.
-12. (Milestone 4.) On the mail page, a mail question by a person, by a time range and by "what needs a reply" finds
-    its target mails, research 066's three failed kinds included; a question with no answer says so; the conversation
-    is a thread readable through the thread seat; and the browser makes no request but to the mail page's own origin.
-13. A batch with one mail that matters sends exactly one `tell` naming it, with no URL, mail address or host name in
-    its words, and the mail is at the top of the page; a sender whose name carries a host name still gives a
-    mail signal, in the safe form.
-14. Research 066's 20 steering mails, read again, mark no injected words as mattering, and every phishing decoy that
-    is marked is a scam warning, which sends no `tell`.
-15. A reading lesson given on a real mail changes how the next mail of that sender is noted; undone, it no longer
-    does; the page lists it.
-16. With the judgement refused (the reader's licence binding removed in the integration test), the condition is
-    raised with its cause, the page shows it over the classical list, no `tell` is sent, and after recovery the mail
-    that arrived meanwhile is read in arrival order.
-17. With `mesh-mail-notifier` unassigned, a new mail that does not matter shows nothing on the laptop or the
-    workstation, and one that matters gives one mail signal.
-
-Tests 1 to 4 are one integration test that starts the module whole against the real bus (playbook 07 step 3 item 4);
-tests 5 and 7 are `mesh-mail`'s own and test 8 `mesh-mail-web`'s, unit tests; test 6 is read before the module is
-assigned; test 9 is proven live after the delivery.
-
-Tests 10's and 11's checks, 13 (with a stand-in router) and 16 are integration tests that start
-`mesh-mail-reader` whole against the real bus and store, with stand-ins for the seats it asks (issues 1431, 1524); the batch's budget, the seat's verbs and the
-mail signal's words are unit tests; tests 10, 13, 14, 15 and 17 are proven live after milestone 2's delivery, test 13
-before `mesh-mail-notifier` is unassigned; test 12 with milestone 4.

-## 11. Milestones
-
-| # | Outcome, in one sentence | Proves | Repositories and their parts | Depends on |
-|---|---|---|---|---|
-| 1 | In a browser on the laptop and the workstation, the operator signs in and browses, searches and reads every account's mail with its attachments, and writes a mail that goes out on their Approve | tests 1 to 9 | mesh-catalog: `mesh-mail`'s account bucket (issue 1255, ADR 0439 §2); the module `mesh-mail-web` (manifest, sign-in, the pages, the send, the seat's verbs, the integration test) | — |
-| 2 | Each new mail is read into a mail group on the mail page; the mail that matters reaches the operator's phone as one mail signal, a scam warning shows on the page only, the operator's corrections become reading lessons, and the pop-up for every new mail is gone | tests 10, 11, 13 to 17 | mesh-catalog: the seat `mail-reading` declared in `mesh-mail`'s manifest; the module `mesh-mail-reader` (batches, mail entries, reading lessons, mail signals, health, the integration test); `mesh-mail-web`'s mail groups, mail signals, scam warnings and reading lessons; `mesh-mail-notifier` unassigned (issue 1418) | 1 |
-| 3 | Betterbird is gone from the laptop and the workstation, its profile and mail kept in the home | ADR 0379 §2 | mesh-catalog: Betterbird unassigned on the operator's Approve, then the `betterbird` module removed from the catalogue (issue 806) | 2 |
-| 4 | **Replaced by design 63** (2026-10-22): on the mail page the operator asks questions about their mail and gets the mails that answer them, in a mail conversation kept as a thread | test 12 | mesh-catalog: `mesh-mail-web`'s mail conversation as a client of the thread seat; the thread's mail tools under a caller of their own (issue 1419); `mesh-mail`'s folder case and `-any` switches | 2 (the reading lessons); design 58's milestone 3 (issue 880) |
-
-**Milestone 1, confirmed by the operator on 2026-10-19, is delivered;** its live proof on the laptop and the
-workstation (a search, an attachment, one send on the Approve) is still the operator's. Its issues, one repository
-part each, in their order: 1255 (`mesh-mail`'s account bucket), 1261 (`mail_send_status` answers only its caller),
-1262 (the module), 1263 (sign-in), 1264 (accounts, folders and mails), 1265 (search), 1266 (a mail and its
-attachments), 1267 (writing a mail), 1268 (the integration test). After its delivery four values were set, each on
-the operator's Approve: `mesh-mail-web`'s `reach` on its machine (`internal`), its assignment there, its
-`operators`, and its caller in `mesh-mail`'s `grants` for every account.
-
-**Milestones 2 to 4, confirmed by the operator on 2026-10-20.** Their issues, one repository part each, in their
-order (each depends on the one before unless said):
-
-- Milestone 2 (its order is said for each): 1426 (the seat `mail-reading` and the module `mesh-mail-reader`), 1517
-  (its database; after 1426), 1518 (hearing new mail, catching up in arrival order; after 1517), 1519 (its health;
-  after 1517), 1427 (a batch's question within its bounds; after 1426), 1520 (running batches; after 1427, 1518 and
-  1519), 1521 (the verbs `entries`, `groups`, `status`; after 1520), 1428 (`correct`, `lessons`, `undo`; after 1521),
-  1429 (a mail signal's words; after 1427), 1522 (sending it; after 1429 and 1520), 1430 (what the mail page shows;
-  after 1428, 1521 and 1522), 1523 (corrections and reading lessons on the page; after 1430 and 1428), 1431 (the
-  reader's integration test; after 1430 and 1522), 1524 (the integration test of failing loudly; after 1431 and
-  1523), 1418 (`mesh-mail-notifier` unassigned; after 1524, the delivery and test 13 live). Issues 1517 to 1524 were
-  split from 1426 to 1431 at the prepare step; issue 1227 (the grants split) will not be done (ADR 0472).
-- Milestone 3: 806 (Betterbird removed; after 1418).
-- Milestone 4: 1433 (`mail_search`'s folder case and `-any` switches; depends on none), 1419 (the thread's
-  caller; a decision first, after design 58's milestone 3, issue 880), 1432 (the mail conversation;
-  after 1431, 1419 and issue 880).
-
-Milestone 2 is one release of `mesh-catalog`: the new seat, the new module and the page change ship together, and
-`mesh-mail-reader` is named in `grants` after that delivery, on the operator's Approve; `mesh-mail-notifier` is unassigned only after test 13 passes live. Milestone 3 is issue 806.
-ADR 0379 §2's bar for removing Betterbird is milestone 1's; keeping Betterbird until mail reading (milestone 2) works,
-and not until the mail conversation, is the lead's proposal, for the operator to confirm with the milestones
-(playbook 04, step 5). **Milestone 4 is replaced by design [63](63-the-mail-web-ui-with-mail-reading-and-owly.md)**
-(2026-10-22): Owly answers mail questions through mail reading before threads exist (ADR 0518), and moves onto a
-thread once they do. Issue 1432 will not be done; issue 1433 moves to design 63's milestone 3; issue 1419 stays
-open for the move onto a thread.

-# 60 — The brother module
-
-**One module serves the operator's Brother multifunction device: its scanner and its printer are one machine on
-the network, so one module, `brother`, holds both seats, `scanner` and `printer`. It scans the glass or the
-document feeder into a PDF, keeps every scan in its own bucket and announces it on the bus, prints a document in
-one call, reads the device's state and its admin pages, restarts it, and changes the settings on the admin pages
-where a mistake cannot lock the operator out or open the device. Only the module's device process ever holds the
-device's admin password or the bucket's key.**
-(ADR 0464, ADR 0467 and ADR 0468 are in force; ADR 0468 is being built, milestones F1 to F3 below. Proposed, and
-not in force: ADR 0475 for the feeder, multi-page and several-document scans; ADR 0474 for
-reading every page, configuring, the refused pages and the restart.)
-
-**Acceptance.** The operator, or an agent through the mesh MCP server, scans a document from the glass and finds it
-cropped in the scan folder; scans five sheets from the feeder on both sides and finds one PDF of ten pages; prints
-that PDF from a file in one call; reads any admin page (ADR 0474, as proposed); changes a setting on an allowed page and is told the old and the new
-value; and is refused, with the reason, when asking to change the admin password or the network settings.
-
-## 1. The parts
-
-```
-caller (an agent, a module, the operator)
-   │  scanner.scan · scanner.status · scanner.list · scanner.document
-   │  printer.status · printer.print · printer.upload · printer.settings
-   │  printer.configure · printer.restart
-   ▼
-brother — tool side (served by the node's tool runner, as the operator account)
-   │  holds no credential
-   │  status reads:  IPP and eSCL, no login ───────────────────────────▶ the device
-   │  every other verb: an ask on the work queue device-asks
-   ▼
-brother — device process (an account and a bus account of its own)
-   │  holds the admin password and the bucket's key, and nothing else does
-   ├── eSCL  ─────────────────────────────▶ the scanner
-   ├── IPP   ─────────────────────────────▶ the printer
-   ├── HTTPS to the pinned certificate ───▶ the admin pages
-   ├── S3    ─────────────────────────────▶ the module's bucket (minio)
-   └── its answer in the state device-answers ──▶ back to the tool side
-```
-
-The two seats are held once for the mesh. A seat names the role, so a later scanner or printer module claims the
-same seat and no caller changes (ADR 0467 §2).
-
-The module has two halves. The **tool side** answers the verbs. It runs as the node's operator account, so the
-scans it files in the scan folder are the operator's, and it never opens a credential. The **device process** runs
-as an account of the module's own with a bus account of its own (ADR 0436 §1), holds no seat and serves no tool. It
-alone reads the admin password and the bucket's key, and it alone does the work that needs either. A verb that
-needs a credential puts an ask on a work queue and reads the device process's answer back from the module's state,
-waiting at most the verb's bound (ADR 0468 §1). The reads that need no credential, the device's state over IPP and
-the scanner's over eSCL, stay on the tool side.
-
-The admin password is the operator's own, given once at the operator's desk and kept in the vault; the mesh never
-generates or rotates it (ADR 0467 §4). The device process speaks HTTPS to the admin pages and trusts only the
-certificate whose SHA-256 fingerprint is pinned in the module's config; any other certificate is refused in the
-handshake, before a password is sent (ADR 0467 §3). The module's pin tests check it: a certificate with another
-fingerprint is refused and nothing is sent.
-
-## 2. Scanning
-
-What ADR 0464 decided is the glass, one page, one PDF page. ADR 0475 (proposed) widens it to the feeder, to several
-documents on the glass and to documents of several scans; until it is accepted, only ADR 0464 holds.
-
-- **The glass.** One page over the whole glass. The document lies on the lid, which is a white of its own, so the
-  module measures the lid where no document lies and cuts the document out of it with a small margin. When it finds
-  no document, or one that fills the glass, it keeps the whole page and says it did not crop (ADR 0464 §3).
-- **Several documents on the glass** (ADR 0475, proposed). Documents lying apart on the glass are each cut out and
-  filed as a PDF of their own.
-- **One document of several glass scans** (ADR 0475, proposed). A caller starts a document, adds a glass scan to it
-  as often as it needs, and finishes it, and the pages become one PDF. A document left unfinished is filed whole
-  after 30 minutes, so no scan is lost.
-- **The feeder** (ADR 0475, proposed). The feeder scans whole sheets, one side or both, and every page of the run
-  goes into one PDF, in the order the scanner gave them: one object in the bucket and one announcement, with its
-  page count. A feeder page is never cropped. A run that is cut off before its end is an error, never a short PDF
-  said as success; a unit test checks it.
-- **A long run** (ADR 0475, proposed). A feeder run may take longer than a call through the mesh MCP server may
-  wait. Such a call answers that the scan started, with an id, and the caller reads its outcome by that id. A scan
-  that was announced is always filed.
-- **The real resolution.** The module reads the resolution from the image it receives, never from what it asked: a
-  scanner may answer a request for 300 dpi with 200 dpi (ADR 0464 §2).
-
-**A lesson for every device the mesh speaks to.** The scanner ignored every scan setting at first: whatever the
-request asked, it ran its own default job. The cause was the request's body: the device ignores a body that holds a
-line break, and the same request written on one line is honoured. A device's protocol implementation may be
-stricter, or stranger, than its standard; when a device ignores a well-formed request, the form of the request
-(line breaks, whitespace, the order of fields) is the first suspect, and a capture of what a working client sends
-is the evidence.
-
-## 3. Printing
-
-A caller prints in one call: `printer.print` takes exactly one of a key in the bucket (`object`), a file on any
-machine of the mesh (`path` with `node`) or a web link (`url`), with the copies, the sides and the paper (ADR 0468
-§5). A file on a machine is sent into the bucket by that machine's node-files `upload`, which refuses the secret
-places a read refuses, and printed by its key (ADR 0468 §9). A web link is fetched by the device process, at most
-60 s, 100 MiB and 5 redirects, and never from an address inside the mesh or a private network (ADR 0468 §6). A
-document that is neither PDF nor JPEG is turned into a PDF by the seat `document-converter`, which only-office holds
-(ADR 0468 §7). The device process then sends the document to the printer in a format the printer itself lists as
-accepted, read before the job.
-
-**No document crosses the bus.** The bus carries a document's key, size, SHA-256 and type; the bytes move over
-HTTP between a party and the object store, on a signed link of at most 10 minutes for one object and one method
-(ADR 0468 §3). The device process signs links for the module's own steps with its binding's key; every other
-party asks `object-store.link`, which minio serves and signs with a key limited to that bucket, for a caller that
-brother's `shares` names (ADR 0468 §8). The parts verbs `printer.upload` and `scanner.document` still serve until
-issue 1569 removes them.
-
-## 4. The bucket and the events
-
-Every scan is kept once in the module's own bucket under its SHA-256, and announced with the event
-`brother.scan.added` once it is stored: its key, size, page count, size in millimetres, resolution and colour mode,
-never the image. The scan folder is one consumer of the stored scans: once the scan is stored and announced, the tool side
-reads it by a link the device process signed and files it there as the operator; the device process never writes
-into the operator's home (ADR 0468 §4). The module deletes nothing from the bucket; the operator removes what they no longer want
-(ADR 0468 §2, §4).
-
-The other events are `brother.printer.restarted`, when the device answers again after a restart (ADR 0467 §6), and
-`brother.printer.configured`, one for each setting changed (section 5).
-
-## 5. Settings: read and configure
-
-**Reading.** `printer.settings` reads one admin page: the device process logs in, reads the page and logs out. It
-answers the page's forms with each field's current value (a radio group's checked button, a checkbox's state, a
-select's chosen option) and the values each field allows; the page's links and its hidden fields only on ask. A
-password field's value is never given. ADR 0467 §5 decides the read for the pages of the scan and restriction
-settings; ADR 0474 (proposed) widens it to every page, and the menu page's links are the map of the rest.
-
-**Configuring** (ADR 0474, proposed). `printer.configure` takes one page and the fields to set on it, by name. The device process logs in
-and reads the page as the printer serves it, with a fresh form token. It checks each named field: the field exists
-in one form of the page, and its value is allowed for its type (one of a radio group's or a select's values, on or
-off for a checkbox, a text within its maximum length). A password, hidden or file field cannot be set. When any
-check fails, nothing is sent and the answer names each refused field with what it allows. Otherwise the process
-posts the form as the page served it: its own hidden fields, the named fields at their new values, and every other
-field at its current value, so nothing the caller did not name changes. It reads the page back, answers each changed
-field's old and new value, and says a field the printer did not take as not taken. Then it logs out.
-
-```
-caller ──configure {page, set}──▶ tool side ──ask──▶ device process
-                                                        login ─▶ read page (form, token, current values)
-                                                        check every named field ──✗──▶ refused, nothing sent
-                                                        post the whole form ─▶ read back ─▶ logout
-                                         ◀──answer: old → new per field
-                                                        brother.printer.configured, one per field
-                                                        told to the operator: page, fields, who asked
-```
-
-**What may not be changed** (ADR 0474, proposed). Some pages are refused, because a mistake on them locks the operator out or opens the
-device to the network: the login password, the user restriction and setting lock, the reset menu, the firmware
-update and its setup, the security settings, every wired, wireless and Wi-Fi Direct network page, the protocol and
-interface pages, and every security page (certificates, TLS, IPsec, the IP and MAC filters). The list is in the
-module's code and its tests, not in a config value, so no call can widen it; it is checked against the page asked
-and against the address the form posts to; a unit test refuses each listed page. The operator changes such a page in a browser at the device itself.
-
-**Who asked, and who is told** (ADR 0474, proposed). Every change names who asked, the caller the bus proved for the call; a call with no
-proven caller is refused. Each changed field is announced as `brother.printer.configured` with the page, the field,
-the old and the new value, who asked and when, and the operator is told through the operator channel, once per call.
-No password is ever in an answer, an event, a message or a log; a unit test reads each of them for it.
-
-**Restarting.** `printer.restart` is decided by ADR 0467 §5; that it goes through the device's reboot page, posting
-that page's own form, is ADR 0474's, proposed. It is the one call that posts to the reboot page, which configure refuses. It is
-refused while the device holds a print or scan job, and waits at most five minutes for the printer to answer again
-(ADR 0467 §5).
-
-**The module's own defaults stay config.** The scan resolution, colour mode and cropping are the module's config
-values, held by the config module and changed through its `config` verb (ADR 0348); they are not trusted values.
-Configure changes the device's pages and never the module's config (ADR 0474, proposed), which a unit test checks.
-
-## 6. Health
-
-The device process's health is its unit. The module's health, as ADR 0475 proposes, compares the certificates the
-printer serves, without a login, with the pinned one, and is unhealthy, naming the new fingerprint, when the printer
-serves one that is not pinned; a printer that does not answer is healthy with a note, and with no printer address set
-the module waits for that setting. Until that is accepted, a changed certificate shows only when a verb is refused. A certificate the device
-serves that is not pinned is refused, and the refusal names the served and the pinned fingerprint. A device serves
-a new certificate after a reset, a firmware update or a certificate's renewal, so a refusal is either that or
-another machine answering in its place; only the operator can tell which, and pins the new fingerprint as a config
-value. A firmware that moves an admin page is said as a page not found, never as success: a unit test replays a
-missing page and expects the error.
-
-## 7. Still open
-
-- **The parts verbs.** `printer.upload` and `scanner.document` carry a document over the bus in parts; issue 1569
-  removes them once their callers use links, and revises ADR 0475 to ADR 0468.
-- **Several printers.** The `printer` and `scanner` seats take one holder; issue 1602 asks for the decision that lets
-  a second printer join.
-- **Restart is not built yet.** `printer.restart` is decided (ADR 0467 §5) and follows `printer.configure`.
-- **Not built yet either:** several documents on the glass, a document of several glass scans and the long run's id
-  (ADR 0475, proposed). The print of a machine's file is ADR 0468's, built in milestone F3.
-
-## Milestones
-
-The milestones build ADR 0468, feature `files-through-the-store`. They are cut by release order: the catalogue's
-merge check reads manifests with the controller the mesh runs, and the controller vendors the SDK, so a new
-manifest field ships SDK first, then the controller and every other strict reader of manifests (the build modules,
-the delivery's indexer), then the catalogue (playbook 07, *a new manifest word*).
-
-| # | Outcome | Proves | Repository | Issues |
-|---|---|---|---|---|
-| F1 | A manifest may name who else may read or write its bucket, and every module has one helper that signs and streams a store link. Usable only by F2 and F3. | ADR 0468 §3, §8 (the field) | mesh-sdk | 1591 (`shares` on a requires of s3-bucket), 1592 (link signing and streaming) |
-| F2 | The controller accepts `shares` and writes it into the consumer's grant. Usable only by F3. | ADR 0468 §8 | mesh-controller | 1593 (take the SDK); depends on F1 |
-| F2b | The build modules read a manifest that names `shares`, so a module carrying it builds. Usable only by F3. | ADR 0468 §8 | mesh-catalog | 1657 (mesh-build-go and mesh-build-node take the SDK); depends on F1; the delivery's indexer takes the same SDK in design 47's own work |
-| F3 | The operator prints a stored scan, a file on any machine (a .docx on a laptop among them) or a web link in one call, and scans land in the scan folder from the store; no document these verbs move crosses the bus (the parts verbs stay until issue 1569). Depends on F2 and F2b. | the acceptance above; ADR 0468 §1–§9 | mesh-catalog | minio: 1594 (a signing key per bucket), 1516 (`object-store.link`, retiring the root-signed link); mesh-files: 1597 (upload, download); only-office: 1595 (`document-converter.convert`), 1596 (the converter process); brother: 1598 (print by key or a machine's file), 1599 (print a web link), 1600 (convert before printing), 1601 (the scan folder from the store) |
-
-Order inside F3: minio, then mesh-files and only-office, then brother; one pull request of `mesh-catalog`.

-# 61 — The print and scan page
-
-**A web page where the people the operator names sign in with Keycloak, print a PDF or a photo and scan from the glass,
-and where only the operator manages the printer. It is a module of its own, `print-and-scan`, that

-
-**Acceptance.** A person named in `users`, on a phone that is not a machine of the mesh, signs in, uploads a PDF
-and finds it printed, and scans the glass and downloads the PDF; that person is refused the printer's settings and

-The page claims the seat `print-and-scan`, held once for the mesh, with the verbs `open` and `status`. It calls
-only seat verbs, never a module's own tool, and knows no device's protocol (ADR 0479 §1).
-
-## 2. Who may do what
-
-The page requires a Keycloak client, as the mail web client does (ADR 0440 §3). Two trusted settings name the
-identities let in, by the ID token's user name: `users` print and scan, `managers` also manage. Both are empty by
-default. A browser that has not signed in is sent to the sign-in; an identity in neither setting gets a refusal page
-that names no holder, document or setting (ADR 0479 §2, §3).
-
-Its route is public, so a person reaches it from a device that is not a machine of the mesh; this is where it
-differs from the mail web client, whose route is internal only (ADR 0479 §3).
-
-## 3. Documents
-
-A document goes from the browser to the page over HTTPS, and from the page into its own bucket by a link the object
-store signs; it never crosses the bus, the page keeps none on its disk, an upload is bounded at 100 MiB (refused by its declared length, or cut at the bound, which stores nothing), and a signed link never reaches a browser, because the links name the store's
-internal name (ADR 0468 §3, ADR 0479 §4). The page takes PDF and JPEG only, judged by their first bytes; any other
-type is refused before anything is stored, and converting other types waits on issue 1650 (ADR 0479 §4). To print,
-the page names its own bucket and the key; its bucket shares reading with the printer seat, and the printer's holder
-asks the object store for the link itself, a process of the holder matching the seat (ADR 0479 §5). A scan is read from the scanner's bucket, which shares reading with the
-page, and streamed to the browser as a download; the page offers the feeder and both sides only once a decision in
-force gives them to the scanner seat's scan (ADR 0479 §6).
-
-## 4. Managing the printer
-
-Every user sees the printer's state. Reading and changing its settings and restarting it are the printer seat's
-verbs, for managers only (ADR 0479 §7). The printer's holder sees the page as its caller, so the page records the
-person: before each such call it announces who asked, what and when, and after it the outcome. Restarting is ADR
-0467's, and so is reading the settings, which ADR 0474 proposes to widen; changing them is proposed in ADR 0474,
-which is accepted and built before the page (ADR 0479 §9).
-
-## 5. Still open
-
-- **Several printers.** The page serves the seats' one holder; issue 1602 asks for the decision that lets a second
-  printer join, after which the page lets the user choose (ADR 0479 §8).
-- **Other types.** A Word, spreadsheet or web document waits on issue 1650's decision (ADR 0479 §4).
-- **Order.** The page is built after design 60's milestones F1 to F3 and after ADR 0474 is accepted and built
-  (ADR 0479 §9).

-# 62 — The bookkeeping portal
-
-**A web page on the private network where the operator, signed in with Keycloak, sees the business's income and
-expenses as the bookkeeping service holds them now, and what is still to do per quarter. The `okioki` module that
-talks to the service moves, whole, from the laptop to the home server, and the page, `okioki-web`, runs beside it.
-Bookkeeping data stays on hardware the operator owns.** (ADR 0481, accepted.)
-
-**Acceptance.** The operator, signed in on a machine of the mesh, opens the page's internal name and sees income and
-expenses per month and per quarter, the same period a year before beside them, including an invoice made in the
-bookkeeping service minutes before; sees the to-do of a quarter, with a quarter the accountant has submitted shown
-as locked; and a browser that has not signed in, or an identity not named in `operators`, sees nothing but the
-sign-in or a refusal.
-
-## 1. The parts
-
-```
-the operator's browser (a machine of the mesh)
-   │  HTTP through the route proxy's internal name, signed in with Keycloak
-   ▼
-okioki-web — renders the pages on the server, keeps no bookkeeping data
-   │  over the bus (NATS): bookkeeping.summary · bookkeeping.todo · bookkeeping.documents · bookkeeping.transactions · bookkeeping.document
-   ▼
-okioki — the one session with the bookkeeping service, on the home server
-   │  HTTPS, the service's own web API, as its web app calls it
-   ▼
-the bookkeeping service (OkiOki)
-```
-
-`okioki` claims the seat `bookkeeping`, held once for the mesh, and serves the verbs the page calls beside the tools
-it has (`okioki_todo`, `okioki_link`, …). `okioki-web` claims `bookkeeping-web` with `open` and `status`, and calls
-only `bookkeeping` verbs, over the bus, never a module's own tool, as the print and scan page calls only seats (ADR 0479 §1).
-`okioki-web` opens no connection to the bookkeeping service and holds none of its secrets or settings: only `okioki`
-holds the service's password and session (ADR 0481 §1, §7). Both are Go, and both live in the `okioki` repository.
-
-## 2. Where it runs
-
-Both modules run on the home server, which is always on and is the operator's own hardware (ADR 0481 §1). The
-laptop sleeps and travels, so a page there would be away whenever the laptop is. `okioki` runs once: the service
-password is sealed on the home server for `okioki` alone, given once at its desk prompt, and the laptop's `okioki` is retired on
-the operator's Approve once the home server's answers.
-
-Uploading no longer reads a folder on the laptop. `okioki_upload` takes a scan from the scanner's bucket by its key,
-or a mail attachment by its account, message and name, and reads it over the bus (ADR 0481 §3); a scan made on any
-machine then reaches the service without being copied between machines.
-
-## 3. Who may see it
-
-The home server's route `reach` is set to `internal` before the page is assigned there, so the route proxy composes
-only the internal name, and the page answers 404 to any other host (ADR 0440 §2, ADR 0481 §6). It requires
-`oidc-client` from Keycloak, as the mail web client does (ADR 0440 §3). A trusted setting `operators` names the identities let in by the ID token's user name; it is empty by
-default, so nobody is let in until the operator names themself. Nothing about the page is public.
-
-## 4. What it shows
-
-- **Overview.** Income (outgoing invoices) and expenses (incoming invoices and receipts, refunds subtracted), excluding
-  VAT, per month and per quarter, the same period a year before beside it; wages and money in and out of the business
-  account from the bank, by the operator's own tags. `bookkeeping.summary` computes it in `okioki` from the service's
-  documents and transactions, so the page does no bookkeeping arithmetic of its own.
-- **To-do.** Open payments and documents per quarter, as `okioki_todo` reads them.
-- **Documents and transactions.** Searchable lists for a period; a document opens as the file the service keeps,
-  streamed through `bookkeeping.document` over the bus in numbered parts, as `scanner.document` answers (part, parts,
-  size, SHA-256, data): `okioki` fetches the file from the service, and the page never follows the service's own link.
-
-The page only reads: it calls no verb that changes the service, and keeps no copy (ADR 0481 §4). Keeping the history in a database of the mesh's own is the own
-bookkeeping research (issue 1457), and a decision of its own.
-
-## 5. What the accountant has done is never undone
-
-Every tool of `okioki` that changes the service, whoever calls it, reads the booking or document first and refuses
-one the accountant has reviewed, approved for sending or booked, naming it and why, and sends nothing (issue 1608,
-ADR 0481 §5). The page shows such items as locked.
-
-## 6. In what order it is built
-
-1. **`okioki` on the home server**: the seat `bookkeeping` with its read verbs, uploads from the scanner's bucket and
-   from mail, the accountant guard (1608); assigned to the home server, its password given at its desk prompt, the
-   laptop's retired on the operator's Approve.
-2. **The read-only page**: `okioki-web` with the overview, the to-do and the lists, behind Keycloak.
-3. **Changes from the page** (linking, tagging, marking paid, closing) are not part of this design: they need a decision
-   of their own (ADR 0481 §4), and would go through the same guarded tools.
-
-## 7. Still open
-
-- **The route proxy on the home server** did not answer its tools on 2026-10-21; whether it serves an internal name
-  there is checked before step 2.
-- **The guard's fields**: which of the service's fields an accountant's submission sets is read from the service
-  before 1608 is built.

-# 63 — The mail web UI with mail reading and Owly
-
-**The mail page stops being a list of mail and becomes the operator's list: what needs them today, this week and
-later, what is promised, what is good to know and what can be read later, each line written by mail reading from
-the mail, never copied from it. Beside it sits Owly, the mail page's assistant, which answers questions about the
-mail, writes drafts the operator sends on their Approve, and suggests tidying the mailbox into an approval inbox,
-where only the operator's Approve changes anything. Every action of the operator on the page is recorded, so mail
-reading and Owly judge better over time. The classical list stays one click away, as All mail.**
-(ADR 0515 to ADR 0519, building on design 59 and ADR 0459.)
-
-The page has no name of its own: it is `mesh-mail-web`'s page, the mail page. Its reference is the mockup the
-operator picked on 2026-10-22, kept beside this design as [`63-mockup/mail-page.html`](63-mockup/mail-page.html), a
-direction and not a pixel specification; its mail is invented, and no name, address, employer, domain, provider
-or amount in it is the operator's.
-
-## 1. What it builds on
-
-Design [59](59-the-mail-web-client.md) delivered the mail web client (its milestone 1) and mail reading (its
-milestone 2): `mesh-mail-web` renders the mail page on the server, and `mesh-mail-reader` reads each new mail into
-a mail entry, sends a mail signal for the mail that matters and keeps the operator's corrections as reading
-lessons. What runs today is the as-is [18](../00-as-is/18-the-mail-modules.md). The operator judged that page
-unusable on 2026-10-22: it shows mail groups over a classical list, so the operator still reads each mail to know
-what it asks.
-
-This design replaces design 59's milestone 4 (the mail conversation on a thread) and its page of mail groups:
-Owly answers before threads exist (ADR 0518) and moves onto a thread once they do, and the page opens on the
-operator's list (ADR 0515 §5). It is a design of its own, not an amendment of design 59, by the operator's choice
-on 2026-10-22: design 59 is the mail web client and mail reading as first built and closes with its own last steps
-(test 13 live, issue 1418, and Betterbird's removal, issue 806); this one is the page rebuilt from a visual design
-(playbook [10](../../00-META/process/10-visual-design.md)), in six milestones of its own. Design 59 says where it is
-replaced.
-
-## 2. The operator's list (ADR 0515, ADR 0516)
-
-- **Mail reading notes what each mail asks.** A mail entry also holds at most 3 tasks (what to do, and by when),
-  at most 3 promises (*you promised*, *waiting on others*, *on its way*, with who and when) and whether the mail is
-  *read later*. Each line is the model's own sentence, at most 120 characters, and never quotes the mail. A batch
-  holds at most 6 mails, so its larger answer stays within 40 s (ADR 0516).
-- **The page opens on the operator's list.** A greeting says what mail signals told the operator today; then
-  *today*, *this week* and *later* (tasks by their due date), *you promised*, *waiting on others*, *on its way*,
-  *good to know*, *read later*, *handled today* with undo, and the scam warnings in their own place (ADR 0515 §1).
-- **Modes choose accounts.** *Work*, *Personal* and *Everything* each show the accounts `mesh-mail-web`'s setting
-  `modes` names (ADR 0515 §4).
-- **Phone first.** One column on a phone; a wide screen adds the reading pane, and Owly beside the operator's list (ADR 0515
-  §2, §3).
-- **All mail is the classical list.** Accounts, folders, search and one mail stay a view the operator can always
-  open; a correction of mail reading is made from the reading pane (ADR 0515 §5).
-- **One script and one stylesheet from its own origin.** The page stays rendered on the server; the script makes
-  handling, undo and Owly work without a reload and talks only to the page's own origin. A mail's body stays
-  escaped text, and an attachment stays a download until milestone 2's decision (ADR 0515 §6).
-- **The operator's list starts full.** After the delivery, mail reading reads the last 14 days of inbox mail once more
-  (ADR 0516 §5).
-
-## 3. Handling and the action log (ADR 0517)
-
-- **Handled is the operator's.** Ticking a task, a promise or a mail handled hides it under *handled today*, with
-  an undo until the day ends; *remind me tomorrow* hides it until the next day. Nothing in the mailbox changes.
-- **Every action is a line in the action log:** handled, undone, reminded, opened, corrected, asked, approved or
-  *not now*, the mode chosen, and the page opened (*last looked*, which gives *new since you last looked*). A line
-  holds the act, the mail by its id, the mode and when, and a question's own words; never mail text. Kept a year.
-- **The log teaches.** Per sender over 90 days, the counts of mails, opened, handled unopened, reminded and
-  corrected reach each batch and each question in a part of their own, at most 4 KiB (milestone 5).
-- **The verbs.** `mail-reading` gains `list`, `handle`, `unhandle`, `remind`, `record` and `actions`; the page
-  calls them for the signed-in operator and keeps no state of its own.
-
-## 4. Owly answers (ADR 0518)
-
-- **`ask` on `mail-reading`.** A question (at most 2 KiB) is answered in two judgements: the first chooses up to 5
-  mails and 3 search terms from the mail entries; mail reading calls `mail_search` and `mail_read`; the second
-  answers from those mails and names only mails it was given. A question the mails do not answer is answered so.
-- **On another node.** Owly's judgements run on the node `ask-node` names (the workstation by default), never on
-  the node of the batches and the issue tracker, so ADR 0459 §15's spacing holds unchanged. An answer takes up to
-  about 90 s, 130 s behind the morning briefing; the page shows how long Owly has been waiting.
-- **The morning briefing** is one judgement a day from the last 7 days' mail entries, read aloud by the browser's
-  own speech on the operator's click.
-- **Nothing of the conversation is kept** but the question, in the action log. A follow-up is answered fresh until
-  Owly moves onto a thread (issue 880, then issue 1419 for the thread's caller).
-- **On the page:** Owly is a panel beside the operator's list on a wide screen and a sheet on a phone, with suggestion
-  chips for the questions the operator's list makes likely.
-
-## 5. Owly writes (milestone 4)
-
-**Proposed scope, not yet decided.** This section is what the mockup shows; its decision is written in
-milestone 4's prepare step, before any of it is built, and the section is then rewritten to it.
-
-Owly offers three short reply options for a mail that asks a question, a draft in the mail's own language, a new
-mail from a sentence ("mail Lena that I'll pick the photos tomorrow"), a nudge for a promise the operator waits
-on, and an answer to an invitation. Every one is the operator's to change, and goes out only through `mail_send`
-on the operator's Approve on Telegram (ADR 0440 §6, ADR 0361 §2). Drafting is outside every decision so far (ADR
-0462 §7 leaves it to issue 1259), and a reply needs `In-Reply-To` and cc (issue 1257): the decision is written in
-milestone 4's prepare step, tracked by issue 1864.
-
-## 6. Owly learns and tidies (ADR 0519, ADR 0517 §6)
-
-- **Suggested actions.** Mail reading may suggest *archive*, *report as phishing* or *unsubscribe*, with why; it
-  carries none out. Batches suggest from scam warnings and from senders the operator never opens; Owly suggests
-  when asked in words.
-- **The approval inbox** on the page shows each, with *Approve* and *Not now*. The signed-in operator's Approve is
-  the decision; `mesh-mail-web` then calls `mail-store`'s new verb. *Not now* keeps a sender quiet for 30 days.
-- **mail-store's writes:** `archive`, `report`, `restore` (the same day's undo) and `unsubscribe`, by the mail's own
-  one-click way (RFC 8058, to a public address only) or as a mail send on the operator's Approve. `mesh-mail`
-  answers them only for the mail web client, which calls them only from the page's Approve and undo forms, so nothing
-  else on the mesh can change the mailbox; an undo writes an *undone* line through `decide`. Flag, delete and draft stay with issue 730.
-- **The action log's counts reach the batches** and Owly's questions, in a part of their own (ADR 0517 §6 to §8).
-- **Teaching in the chat (proposed scope, not yet decided).** "Stop telling me about Strava" becomes a reading
-  lesson, shown under *Owly learned* with an undo. Whether a lesson taught in words needs more than ADR 0459 §8
-  decides is settled in milestone 5's prepare step, tracked by issue 1866, before it is built. *Remind me tomorrow*
-  and *read later* are milestone 1's (ADR 0516, ADR 0517).
-
-## 7. Fast on the desktop (milestone 6)
-
-**Proposed scope, not yet decided:** its decision is written in milestone 6's prepare step, tracked by issue
-1867, before it is built.
-
-Keyboard shortcuts (`j` and `k` move, `x` ticks, `r` opens the reply options, `/` jumps to Owly, `?` lists them)
-and bulk actions (tick several, handle or archive them at once, each archive still on the approval inbox's
-Approve). Tracked by issue 1867.
-
-## 8. What stays outside
-
-- **A calendar.** "Put the viewing in my calendar" needs a calendar on the mesh; none exists, so the page shows the
-  date and offers nothing more. No issue is opened until a calendar is decided.
-- **Attachments shown in place** change ADR 0440 §5 (an attachment is only a download); milestone 2 writes that
-  decision before it builds (issue 1861).
-- **The mail conversation on a thread** waits for threads (issue 880) and its caller (issue 1419); ADR 0462 then
-  decides again for Owly.
-- **The work account** stays a later decision of its own (ADR 0359 §7).
-
-## 9. The build's acceptance tests
-
-1. Each new mail's entry holds its tasks, promises and read-later mark; every line is at most 120 characters and
-   shares no run of 8 words with the mail's text; a batch holds at most 6 mails and its question stays under 64
-   KiB (ADR 0516 §1 to §3).
-2. A correction removing a task or a promise, or changing the read-later mark, is kept as a reading lesson and
-   followed by the next batch (ADR 0516 §4).
-3. After the delivery the last 14 days of inbox mail are read once, and a restart does not read them again
-   (ADR 0516 §5).
-4. The mail page opens on the operator's list: the greeting with today's mail signals, the sections in their order, scam
-   warnings in their own place, the modes from `modes`, and *All mail* opening the classical list (ADR 0515).
-5. Handling a task moves it to *handled today*, undo returns it, remind hides it until the next day, and each act
-   leaves one line in `actions` with no mail text; a line older than 365 days is removed (ADR 0517).
-6. Every page's content security policy allows script and style from its own origin only, no inline script, and
-   `connect-src 'self'`; a mail body with `<script>` and a remote image is shown as text (ADR 0515 §6).
-7. Tests 1, 2, 4 and 5 run in one integration test that starts `mesh-mail-reader` and `mesh-mail-web` whole
-   against the real bus and store, with a fixed judgement (issue 1860).
-8. Live: the operator uses the operator's list on the phone and on the desktop for a day.
-9. (Milestone 2, proposed until its decision.) A photo, a PDF's pages, an invitation, a sheet and a zip's contents open in place, as its decision
-   says (issue 1861).
-10. (Milestone 3.) `ask` answers naming only mails it was given, says so when nothing answers, never judges on the
-    batches' node, and records the question with no answer text; the morning briefing is one judgement a day from
-    the entries alone (ADR 0518).
-11. (Milestone 3.) Live: the operator asks three questions on the phone and the desktop, and each answer names
-    real mails.
-12. (Milestone 4, proposed until its decision.) A reply option, a draft and a nudge each reach the operator's Approve on Telegram, and nothing
-    is sent without it (issue 1864).
-13. (Milestone 5.) A suggestion appears in the approval inbox; Approve archives the mail, undo restores it,
-    *Not now* is recorded and not suggested again for 30 days; a one-click unsubscribe refuses a private address;
-    `mesh-mail-reader` invokes no write verb (ADR 0519).
-14. (Milestone 5.) The per-sender counts reach a batch's question in a part of their own of at most 4 KiB, the
-    batch's senders first, and the reading lessons keep their 12 KiB (ADR 0517 §6); a lesson taught in the chat
-    changes the next batch and is undone from *Owly learned* (proposed until its decision).
-15. (Milestone 6, proposed until its decision.) Each shortcut does what section 7 says, and a bulk handle of five tasks is five lines in the
-    action log.

 | [`56-the-mail-client-set-up-by-the-mesh.md`](56-the-mail-client-set-up-by-the-mesh.md) | **Designed.** On every node with a display server, the `betterbird` module installs Betterbird from a pinned upstream release mirrored into the artifact store, ships the Owl add-on pinned and installed by Betterbird's enterprise policy, and declares the operator's mail accounts in a trusted setting without credentials; each account signs in once at a person's first use, and one the profile already holds is adopted by its address | ADR 0316, ADR 0317 |
 | [`57-building-config-and-provisioning.md`](57-building-config-and-provisioning.md) | **Designed.** The work of ADR 0348 and ADR 0349 as 37 packages, each an issue with its proof: foundations, template files, config in its own module, the provisioner and its client, secrets in the vault, bindings from providers, collections, a module's runtime readers, and removing the old forms; at most five worked at once | ADR 0348, ADR 0349 |
 | [`58-agent-work-as-the-meshs-own.md`](58-agent-work-as-the-meshs-own.md) | **Designed.** Agent work as the mesh's own: a thread seat keeps every thread whole on the bus; a thread handler runs the harness headless in a sandbox per session, the workspace on the thread's own forge branch; a workspace toolkit and named tools, no general command runner; one identity seat for persons, agents and modules, roles of grants, every tool an effect, signed bus logins, and the switch to them one identity at a time | ADR 0383, ADR 0384, ADR 0385, ADR 0386, ADR 0387, ADR 0388, ADR 0389, ADR 0390 |
-| [`59-the-mail-web-client.md`](59-the-mail-web-client.md) | **In progress.** The operator's mail, every account, in a browser on the mesh's own machines: a module of its own, `mesh-mail-web`, holds `mail-webclient`, renders pages on the server and reads and sends only through `mail-store`'s verbs under a caller granted per account; its route reaches the private network only, the operator signs in with Keycloak, and a mail goes out only on the operator's Approve; then Betterbird is removed | ADR 0440, ADR 0378, ADR 0379 |

-| [`61-the-print-and-scan-page.md`](61-the-print-and-scan-page.md) | **Designed.** A web page, behind a Keycloak sign-in and on a public name, where the people the operator names print a PDF or a photo and scan the glass, and only managers manage the printer: a module of its own, `print-and-scan`, that calls only the printer, scanner and object-store seats, so any holder of those seats works with it; documents go from the browser to the page and by signed links to the store, never over the bus | ADR 0479, ADR 0468, ADR 0440 |

-| [`63-the-mail-web-ui-with-mail-reading-and-owly.md`](63-the-mail-web-ui-with-mail-reading-and-owly.md) | **In progress.** The mail page becomes the operator's list: what needs them today, this week and later, what is promised, what is good to know and what can be read later, written by mail reading; Owly beside it answers, writes drafts sent on the operator's Approve, and suggests tidying into an approval inbox; every action on the page is recorded so reading judges better; in six milestones | ADR 0515, ADR 0516, ADR 0517, ADR 0518, ADR 0519 |
