Merge pull request 'Design the brother module whole: scanning, the feeder, printing, settings read and configure' (#448) from design/60-the-brother-module into main

The operator asked on 2026-10-21 to configure the printer and scanner easily, or through
the mesh's tools; the design names the configure verb, its deny list and the proposed
decision it rests on (ADR 0474, number to be reserved).

+description: Use when the operator asks to clean up the forge and the working copies — stale or merged branches, old pull requests, finished worktrees, leftover folders, stashes. Triggers on "cleanup", "clean up our repos", "stale branches", "old worktrees", "tidy the forge". Reads first, deletes only what the operator approves, and reports what it cleaned, kept and left.

+
+Runs playbook [09 — Cleanup](../../../00-META/process/09-cleanup.md); the playbook is authoritative. This skill
+adds the mechanics.
+
+## 1. Take stock (one read-only agent, smaller model)
+
+Brief it to change nothing and to write one report to the session's scratchpad:
+
+- **Forge.** `gitea.gitea_list_repos`; per repository its default branch and **every branch from the git refs**
+  (`gitea.gitea_api` GET `/repos/{owner}/{repo}/git/refs/heads`; the list tool misses branches, issue 949);
+  `gitea.gitea_branch_protection_get`; open pull requests (`gitea.gitea_open_pulls`, titles and update times
+  from `gitea.gitea_api` `/repos/{owner}/{repo}/pulls?state=open`). Per branch: contained in the default branch
+  (`gitea.gitea_contains`, with the default branch's sha), patch-equal (`git cherry` in a local clone), tip date.
+- **Local.** Under the projects folder: each clone's `git worktree list --porcelain`, `git branch -vv`,
+  `git branch --merged origin/<default>`, `git stash list`, `git status --porcelain` per worktree; folders and
+  loose files beside the clones with `du -sh` and newest file. A worktree under another session's scratchpad is
+  Kept.
+- A **Missing tools** section: each read it did without a mesh tool.
+
+## 2. Classify and ask
+
+Classes as playbook 09 step 2: Safe, Likely safe, Kept, Unknown. Tell the operator the counts and the report's
+place, and ask one question: delete the Safe list? Likely-safe and Unknown items are asked separately.
+
+## 3. Delete the approved list only
+
+- Forge branch: `gitea.gitea_delete_branch`.
+- Worktree: `git worktree remove <path>` (never `--force`), then `git worktree prune`.
+- Local branch: `git branch -d <name>` (never `-D`).
+Once design 58 milestone 7 is built (issue 884), each deletion is a call held as an ask: the operator approves
+the exact list on Telegram and the mesh carries it out on the warrant. Until then a session's permission check
+refuses these; hand the operator the approved list as a file, with the commands, and do not work around the
+refusal.
+
+## 4. Report
+
+Four lists: **cleaned** (with its evidence), **kept** (why), **unknown** (what it looks like), **the operator
+kept** (their word). Open each missing tool with `issue-tracker.open`, or note it on an existing issue.

+- **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 and builds one fingerprint once), the **checker** (the merge check on built

+  view** (`mesh-delivery-cli` and a web view, writing only its answers to asks). 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, the builder by its own module's fingerprint, and a build resolving packages by its lock. 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).
+- **want** and **have** — a want (`want.<node>.<module>`) is the fingerprint a node should run, written by the
+  assigner; a have (`have.<node>.<module>`) is what the node runs, its phase and health, written by that node's
+  agent (ADR 0429 §4, §6). A node's facts that no module owns are its node key. They replace assignments and
+  rollouts at release 6 (§17); 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

+**Uses:** operator, person, module, seat; grant, identity (Identity and access); ask, warrant, operator channel,
+content rule, untrusted input (Operator and conversation). A *judgement* is one call of the model with no tools
+and no session (ADR 0278), in its plain sense.
+
+- **mail account** — one of the operator's mailboxes that `mesh-mail` holds, of a kind of adapter (`imap`,
+  `imap-oauth`, `graph`), named by its address (ADR 0359 §1).
+- **`mail-store`** — the seat holding the mail accounts: `accounts`, `search`, `read`, `send`, `send_status` (ADR
+  0378 §2, ADR 0440 §7). Always the seat's name: the bare *store* is Core's.
+- **mail event** — what `mesh-mail` publishes on its stream `MAIL` for a new, changed or removed mail: headers,
+  flags and attachment references, never a body (ADR 0359 §2).
+- **mail send** — a mail the mesh sends, which goes out only on the operator's warrant for that one mail (ADR 0361
+  §2), with the states `mail_send_status` answers (ADR 0440 §7). Any caller `mesh-mail`'s `grants` names for that
+  account may ask for one (ADR 0472).
+- **mail web client** — the module `mesh-mail-web`, holder of `mail-webclient`: the operator's mail in a browser on
+  the private network (ADR 0440 §1). The page it serves is the mail page.
+- **mail notice** — `mesh-mail-notifier`'s desktop pop-up for a new inbox mail (ADR 0378 §7, §9). It retires when
+  `mesh-mail-notifier` is unassigned everywhere (ADR 0461 §7) and then moves to *mail signal*'s *Not:* line
+  (issue 1418).
+- **mail reading** — the model's reading of each new mail as it arrives, in batches, into its mail group and mail
+  entry; the seat `mail-reading`, held by `mesh-mail-reader` (ADR 0459). Not *triage* (the issue tracker's
+  judgement), and not `mail_read`, `mail-store`'s tool that fetches one mail's text.
+- **mail entry** — what mail reading keeps about one mail: its mail group, a one-line summary, its mark and why, a
+  due date; never the body (ADR 0459 §4). Not *catalogue entry*: the catalogue is Delivery's.
+- **mark** — what a mail entry says the mail is to the operator: *matters*, *scam warning* or neither, never two
+  (ADR 0459 §7). Not *kind* (Media's).
+- **mail group** — a set of mails the model put together because they belong to one subject (ADR 0459 §4). Not *delivery
+  group* or *account group*.
+- **reading lesson** — one correction the operator made on the mail page (a mark or a mail group), kept so later
+  mail reading follows it (ADR 0459 §8 to §10). Always qualified: the bare *lesson* is Operator and conversation's.
+- **mail signal** — the notice on the operator's channel, one `tell` per batch in words only, and the place at the
+  top of the mail page, that tells the operator mail matters (ADR 0461). Always qualified: the bare *signal* is
+  Health and repair's.
+- **scam warning** — the mark of a mail the model judges an attempt to deceive the operator, with why; shown in
+  its own place on the mail page and never a mail signal (ADR 0459 §7, ADR 0461 §6).
+- **mail conversation** — a thread (ADR 0383) with a mail context, followed on the mail page: the mail questions
+  and their answers, each answer with the mails it found. The mail context is the framing that a mail is data, the
+  tools `mail_search` and `mail_read` only, the operator's senders and folders, and the reading lessons (ADR 0462).
+- **mail question** — what the operator writes in the mail conversation to find or understand mail. Not *ask*
+  (Operator and conversation's request for the operator's input).

-A feature that cannot be developed in about two hours is split into **steps**. Each step runs all five

+**One milestone is one release** (the operator, 2026-10-17). A milestone is developed whole, tried before its review, reviewed once,
+opened 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 plan of waiting, so the fewest cuts is the fastest. Milestones are cut by
+release order when the design is broken up (playbook [04](04-build-handoff.md)); a release-order dependency found
+inside a milestone is a fault of that cut, said to the operator, never a silent extra step.
 
-**Scope is fixed at phase 0.** An issue found during a feature goes to the next step or the next feature,
+**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 has its delivery plan done. A
+lead who finds another design's milestone already in `fixing` asks its owner before starting its own. A small

    (`git worktree add .work/<slug>/<repo> -b feat/<slug> origin/main`). The lab beds find the other

+   `main` (`git worktree add --detach .work/<slug>/mesh-tools main`), never symlinks. **A repository's own

+   there, so a session that opens in it reads what holds now; fetch and fast-forward it before reading.
 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. 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), the test to write first, done-when in one sentence;
+     with (quoted, with where each was decided), and its acceptance criteria (item 5), each with the test that
+     proves it;
    - 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 forge's checks run).
+     integration tests, which `mesh-controller.try` and 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. **Move the issues to `fixing`**, `by` naming the feature's agent for that repository.
+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 delivery plan moves, 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. **Look for the orders a release hides, before any agent starts** (2026-10-18: design 47's release 1-2 was cut
+   as one milestone and its prepare step found three orders inside it, each a cut of its own). Read, for each
+   repository of the release, what it takes from the others and how: an SDK change still ships before its users
+   (they vendor a pinned SDK, and a pin to a commit no branch holds is a download that fails later, issue 1148);
+   a new key on the wire between the controller and the node-engine is sent only to a node that says it reads it,
+   since the node-engine's decoder refuses an unknown key; the first module of a repository the catalogue has never
+   built registers only by the route the controller allows for it; and a part that needs something the bus or a
+   manifest cannot yet give (an event only a system account hears, a bucket whose keys expire) needs its decision
+   first. Each order found is said to the operator with the cut it asks for, never built around.
+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. **Move the issues to `fixing`**, `by` naming the feature's agent for that repository.

+  code does, and passes after. **A test that fails only because it does not compile has not failed first**: where

+  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

+  the criterion it proves by its label (`// 1118/AC2`), and no criterion left without its test; an integration criterion is a test

+  or a process) are run first by that try, and again by the forge's merge check.
+- **No pull request is opened in this step. When every issue is committed, the lead brings each feature branch up

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. 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).

-## Is the coast clear?
+## Step 3 — Check (no review)
 
-Before the push of phase 3 (and of a small fix, playbook [08](08-small-fixes.md) step 5), the lead checks, for every
-repository the change touches, whether a **release branch** is in flight there: a branch other than `main` that
-collects a feature's merged work to bring it into `main` as one delivery.
-
-1. **Look for one.** A pull request into `main` whose head is a release branch (`gitea.gitea_open_pulls`), a
-   release branch holding merged work that `main` does not have yet (`git log origin/main..origin/<branch>`), or
-   a delivery plan of that release branch still running (`mesh-controller.plans`).
-2. **Compare the files.** `git diff --name-only origin/main...origin/<release branch>` against the files the
-   change touches.
-3. **Overlap: hold.** If the release branch touches a file the change touches, nothing is pushed into that repository
-   until the release branch's delivery plan is done. Then the feature branch is brought up to the new `main`, the unit
-   tests run again, and the push follows. The hold is on the wait list (its bound: the release branch's delivery plan),
-   and is said to the operator with what the change waits for.
-4. **No overlap: go on.** A release branch in another repository, or one that shares no file with the change, does not
-   hold it; its merge joins the merge window as any other (ADR 0276).
-
-Merging beside a release branch still in flight would make its lead resolve someone else's conflicts in the
-middle of it, and could send part of the change with its delivery (2026-10-16: the file module's
-controller part touched four files feature 57's release branch also changed).

-## Phase 3 — Check (no review)
-
-1. **Push every feature branch and open one pull request per repository, together, once the coast is clear**

-   run only in the merge check (the operator, 2026-10-16), never before. Pull requests in two or
+1. **Push the reviewed heads, try again a head the review changed, then open one pull request per repository,

+   and again for a head the review changed since its try: `mesh-controller.try` with the
+   repository and the pushed branch runs the repository's `merge-check.sh` (main's version) on the merge, in the
+   toolchain containers and against the throwaway store and bus a merge check gets, and answers with an id to
+   read back. A try that fails goes to step 3 item 3 as a failed check does; the pull requests are opened only
+   when every head's last try passed (the operator, 2026-10-18: three pushes in a row failed their first merge check on
+   faults a try finds in minutes). Never `merge-check.sh`, `go test -tags integration` or a store or bus started
+   by hand on the machine (the operator, 2026-10-18). Pull requests in two or
    more repositories that share the branch name are one delivery group (ADR 0239 §2).
    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.
-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
+   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.
+   **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 try 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 forge's merge checks run the integration tests again, as the gate** (`mesh/merge-gate`, `mesh/repo-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 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 change to `merge-check.sh` is judged by main's version of it**, so a test the change adds must pass under
+   either version: one that runs the new script's behaviour runs a file of its own, never `merge-check.sh` itself.
+   **So a change that needs the new script to judge it ships the script 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 runs that tag, and main's script would have skipped every
+   tagged test, its acceptance tests among them. The prepare step looks for this: a change to `merge-check.sh` or to
+   what it selects (build tags, the store-tests list) is cut ahead of the milestone.
+4. **The milestone's acceptance is proven by its check.** A milestone 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 step's acceptance sentence; the forge's checks run it (ADR 0391 §1, §6). Unit tests alone are not

-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
-   (ADR 0364). 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.
+   **A new manifest word's test goes through the push that meets it first, 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 both checks 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. 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.
 
 **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. Plan such a feature as two steps.
+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.
+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.

+forge serves only later; issue 1542, the node-engine refusing the module's own `.ssh`). So a new module is assigned

+**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 plan, 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 delivery, 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`,
+`mesh-controller.plans`, `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 plan: on
+2026-10-19 one watcher sent on to three pull requests in turn missed that the third's checks had passed at 04:58,
+and the lead told the operator for 15 minutes that they were still running. The next wait gets a fresh watcher,
+and before a report the watcher reads the owning verb once more and says only what it says now.

+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's delivery plan is done:** 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

-   Commit, naming the issue. For a playbook or design edit, run the repository's own checks (in hq,

+   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).

+# Playbook 09 — Cleanup
+
+**Trigger.** The operator asks for a cleanup, or the forge and the working copies have gathered what nobody
+uses: merged branches, stale pull requests, worktrees and folders of finished work.
+
+**Who runs it.** A session on the operator's word, with the operator deciding every deletion. Agents read and
+propose; a deletion is the operator's act or is done on the operator's word for the list it was shown.
+
+## The aim
+
+Remove what is provably done, and nothing else. A cleanup that deletes one piece of unfinished work costs more
+than every stale branch it removed. So every item is shown with its evidence, and anything not provably safe is
+reported and left.
+
+## Steps
+
+1. **Take stock, reading only.** One agent on the smaller model reads, changing nothing:
+   - the forge: every repository, every branch **as git refs** (the branch list tool misses some, issue 949),
+     every open pull request with its head, title and last update;
+   - each working copy on the machine: its worktrees, local branches, stashes, and the folders beside the
+     clones, with size and newest file.
+   It writes one report with each item, its class and its evidence, and a list of the tools it lacked.
+2. **Classify each item**, by evidence, never by name or age alone:
+   - **Safe** — a forge branch whose tip is contained in its repository's default branch, with no open pull
+     request, not protected and not a long-lived branch the mesh treats as a trunk; a worktree that is clean,
+     whose branch is contained in the remote default branch, untouched for two hours and not in another
+     session's working folder; a local branch contained in the remote default branch.
+   - **Likely safe, not proven** — a branch whose every commit is patch-equal to one on the default branch
+     (the forge lands some commits under new hashes): listed, deleted only on the operator's word for it.
+   - **Kept** — unmerged commits, a dirty worktree, a stash, an open pull request, a protected or trunk-like
+     branch, a repository of another owner, another session's worktree.
+   - **Unknown** — a folder or file outside git: described, never opened where a secret may be, left.
+   Stale open pull requests (no update for three days) are reported with their author's issue, never closed.
+3. **Ask the operator** with the counts per class and the report's place. One question: delete the safe
+   items as listed? The likely-safe and unknown items are separate questions, item by item when few.
+4. **Delete only the approved list**, each with the command that refuses an unsafe case (a worktree removal
+   that refuses a dirty one, a branch deletion that refuses an unmerged one). A refusal is reported, never
+   forced. The operator approves a deletion on a channel that proves who answered, as an ask bound to that
+   exact list and carried out on the warrant (ADR 0387, design 58 milestone 7, issue 884). Until that is built,
+   an agent session's permission check refuses these deletions, and the approved list is handed to the
+   operator to run.
+5. **Report**: what was cleaned, what was kept and why, what was unknown, what the operator kept, and the
+   missing tools, each opened as an issue (`issue-tracker.open`) or added to an existing one.
+
+## How it is checked
+
+- The report names, for every deleted item, the evidence it was safe (contained, clean, no pull request).
+- Nothing classed Kept or Unknown is deleted without the operator's word for that item.
+- A cleanup's missing tools are issues, not notes in a session.

-# Delivery — from a push to a running node
+# Delivery — from a merge to the nodes, as it runs
 
-One trigger, three silos, and a fan-out point that is the most consequential boundary in the
-mesh.
+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.
 
-## The trigger
+## Who does what
 
-A push to the forge. The forge calls a webhook; the receiving module verifies its signature
-and emits an event. The coordinator resolves which modules the pushed commits affect, orders
-them into dependency levels, and creates a pipeline per level.
+- **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.
 
-There is no second path. A manual trigger exists for a module the push detection missed, and
-using it routinely is a sign the detection is wrong rather than a workflow.
+## From a merge to a rollout
 
-Detection is the pipeline's most fragile input. It has failed for reasons that have nothing to
-do with the change: a webhook truncating its commit list on a large merge, a forge address
-whose port broke the module-path matching. The characteristic outcome is the bad one — **a
-merge that created no pipeline, and nothing said so**.
+- **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.
 
-## Three silos
+## Checks
 
-Cardinality is the whole point, and the three differ
-(ADR 0010):
+- 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.
 
-| Silo | Runs | Where | Does |
-|---|---|---|---|
-| **build** | once per module feature | the build node | compile and bundle into a self-contained output |
-| **publish** | once per module feature | the build node | package that output and upload it; a package-registry feature publishes here |
-| **deploy** | once per module feature **per node** | every assigned node | install, configure, start, verify |
+## Where the record of what runs lives
 
-Commands and events are addressed per feature, not per module.
+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.
 
-Build hands over a **staged tree**, not a package. Packaging belongs to publish, so a failed
-upload retries by re-packaging rather than by re-sending something stale, and build never needs
-to know how each module composes its artifact. The handover is a tree in a known location,
-because the build's own working directory is reference-counted and may be gone by the time a
-later stage runs.
-
-## The artifact
-
-The artifact is **build output** — compiled and bundled with its dependency graph inlined —
-never a filtered copy of source (ADR 0010).
-A deploy is extract-and-run and touches no network.
-
-The consequence is the whole cost of the decision: **anything not in the build output does not
-ship.** Every file kind had to be brought into that rule separately, and each was discovered by
-something silently not happening after deploy — migrations reading a source layout, provisioning
-scripts reading a source layout, selection files never packaged at all.
-
-## The fan-out, and the build node
-
-After publish, work fans out to every assigned node. The build node is the only node that has
-already passed through two silos when this happens, and that asymmetry has its own defect
-class: anything advancing a node's stage must account for **both** pre-fan-out stages. Code
-that knew only about the first parked the build node forever while every other node deployed
-cleanly — and the recovery sweeper, which knew the same subset, reported nothing to recover.
-
-A recovery mechanism that knows less than the thing it guards is worse than none, because it
-reports success over a stall it cannot see.
-
-## Levels
-
-A level completes before the next begins, so a module builds against its dependencies as they
-were just published. The shared library is at level zero, which means anything that breaks it
-breaks the first module of every cascade.
-
-## What green proves
-
-**A green pipeline proves transport, not effect.** The stages report that a message was
-dispatched and accepted, which is not the same as the thing being running, correct, or present.
-
-This is the mesh's most consistent failure shape and it is not incidental to the design — it is
-what the stage reporting currently measures. Documented instances include a service reported
-started when the container command merely returned, an image pull failure that did not fail the
-deploy, a package install that 404ed from every mirror while the job went green (see
-[`04-ISSUES/001`](../../04-ISSUES/001-failed-package-install-reports-success/00-report.md)),
-and a node left on old code after a failed artifact download with a version marker that had
-already advanced.
-
-A verify stage exists to close this gap. It has been built and, for a period, was never
-scheduled, because the coordinator's stage list did not include it.
+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
 
-The end-to-end harness for this pipeline has not built since the workspace was removed, and
-nothing reports that nothing runs it
-([`04-ISSUES/005`](../../04-ISSUES/005-pipeline-test-harness-unbuildable/00-report.md)). The
-pipeline's coverage is currently assumed rather than checked — which is the same class of claim
-this repository exists to make people stop making.
+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'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.
+**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.
+
+## 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. `mesh-host` and `mesh-controller` supervise, compose and account for it as a core
+process rather than as an ordinary assignment (`ComponentNodeTools`/`BusNodeTools` in both, the
+witness and lease code that restarts and rolls it back, the account named `<node>.node-tools` on
+the bus).
+
+**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`.
 
 ## What it answers
 
-`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.
+`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`).
 
-`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.
+**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 2026-10-17 it answered 103 modules and 645 tools across the whole mesh, with
+two module instances (`route-proxy` on two of the nodes) named as not answering rather than silently
+absent.
 
-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.
+**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.
 
 ## The mesh's own verbs
 
-*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.
+**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, the mesh-controller runtime is one instance, mesh-wide, and it answers 63 verbs for that one
+seat (`status`, `push`, `assign`, `build`, `artifacts` and the rest), and 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-agent`, `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.
 
-## Around it
+## Where it runs
 
-- **`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.
+**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.
 
-## What shipped bent
+## What this repository's prior text got wrong
 
-- 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.
+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.

+# 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.

+**One module, `mesh-mail`, holds every mail account and is the mesh's one `mail-store`. A second module,
+`mesh-mail-web`, is the mesh's one mail web client. A third, `mesh-mail-notifier`, shows a

+send from it, only when `mesh-mail`'s trusted setting `grants` names it for that account — one list per
+account, giving both at once, to the same callers. A send is never performed by a tool: it is queued for a
+process of its own, which sends only once the operator approves it on Telegram.** Read from `mesh-catalog` on
+`origin/main` at `a67f0196` (2026-10-20) and from the live mesh through the mesh MCP server on 2026-10-20.

+
+## 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.
+- None of the three seats is named `mesh-*`. A caller reaches them by seat (`mail-store.<verb>`,
+  `mail-webclient.<verb>`, `mail-notifier.<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
+  2026-10-20): `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; and the control-node's `mesh-mail-web`.
+  So the notifier, every machine's agent sessions, and the web client can each both read an account's mail and
+  ask to send from it, from the one list.
+
+## 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`) — plus the sign-in callback (`/signed-in`). Every changing form (today, the send)
+  carries a token bound to the session (`server.go`, `csrf.go`).
+- **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 2026-10-20). 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 writes nothing of its own.** No database, 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).
+
+## 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`).

+  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

+repository keeps no copy of the records, generated or otherwise (issue 435, answered by the operator). Playbooks
+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.
+
+```
+  issue tracker ── issues with a design link ──┐
+                                               ├──▶ knowledge base ── works out ──▶ the design's state
+  mesh-delivery ── "delivery done", bus ───────┘                                    (served by get, ask)
+```
+
+**The rules.**
+
+| Case | State |
+|---|---|
+| 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
+end at `delivered`. This slice is an extension after design 47's last milestone. It changes none of design 47's
+milestones and nothing of how a delivery runs; it only listens for the announcement.

+### 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).

+- [Mission](../../00-META/mission.md): agents "hold identity", and there is one kind of participant, some of them

+- [Context](../../00-META/context.md): "Identity is mesh-internal", with no directory and no SSO, so the identity seat

+# 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).
+

+```
+
+- **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.** 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)
+
+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.

+| 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 |

+
+**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 waits for threads and for the decision that names its thread's caller (issue 1419, which needs a decision first).

+# 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; ADR 0468 and ADR 0474, both proposed.)
+
+**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 in one call; reads any admin page; 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
+certificates whose fingerprints are pinned in the module's config; any other certificate is refused in the
+handshake, before a password is sent (ADR 0467 §3).
+
+## 2. Scanning
+
+- **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.** Each scan is its own call and its own PDF; the operator lays the next document on the glass
+  and calls again.
+- **The feeder.** The feeder scans whole sheets, one side or both, and every page of the job goes into one PDF, in
+  the order the scanner gave them. A feeder page is never cropped.
+- **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 a kept scan by its key, or a document it has uploaded, with the
+copies, the sides and the paper. The device process fetches the document from the bucket and sends it to the printer
+in a format the printer itself lists as accepted, read before the job; a document in another format is refused with
+the printer's list (ADR 0468 §5). A document larger than one bus message travels in parts, each under the bus's
+limit, and a caller joins or sends the parts and checks the whole by its SHA-256 (ADR 0468 §3).
+
+## 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: the tool side fetches the scan and files it
+there as the operator. 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. Every page may be read, and the menu page's links are the map of the rest.
+
+**Configuring.** `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.** 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. The operator changes such a page in a browser at the device itself.
+
+**Who asked, and who is told.** 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 or a message.
+
+**Restarting.** `printer.restart` restarts the device through its 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 a proposal on the operator's Approve; configure changes the
+device's pages and never the module's config.
+
+## 6. Health
+
+The tool side's health is whether the scanner answers; the device process's is its unit. A certificate the device
+serves that is not pinned is refused, and the refusal names the served and the pinned fingerprints. 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.
+
+## 7. Still open
+
+- **A certificate change said before a call fails.** Today a changed certificate shows only when a verb is refused;
+  the module should raise it as its condition, naming both fingerprints. No decision holds it yet.
+- **Files off the bus.** Documents cross the bus in parts today (ADR 0468 §3). ADR 0468 is to be revised so that a
+  document travels through a signed link to the bucket instead, and only its key crosses the bus.
+- **Restart is not built yet.** `printer.restart` is decided (ADR 0467 §5) and follows `printer.configure`.
