Subject: [PATCH 001/243] GEN1: the seat generator refuses a definition whose
 callers entry is no form of the format
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The generator checks each verb's and accepted kind's callers in a definition and a part before reading it, naming the
file, the verb and the entry; text is refused as one entry; the contracts it writes carry no caller check.

Builds: design 47 G §336, §339, §392

Subject: [PATCH 002/243] GEN2: the seat generator emits each TypeScript
 contract as index.js with its index.d.ts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A seat's npm package holds index.js, index.d.ts and parts/<part>.js with .d.ts, with no TypeScript source and no
tsconfig.json, so a TypeScript module imports it with no build step and no tsc of the contract.

Builds: design 47 G §341

Subject: [PATCH 003/243] GEN3: the seat generator reads acts, subject, keep
 and callers and writes each event's subject and stream
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

An event whose subject carries parts is published by a function taking each part and heard by a filter with a * per
part; an event naming keep gets the stream SEAT_<seat>_<event>, in Go and in the TypeScript contract. The reader of the
sdk's reader release reads acts (every, a language, kind:image), keep as an object and callers as a list.

Builds: design 47 G §89, §203, §238, §260, §324, §331, §396, §397

a level with no test left out; the manifest serves it.

From 25bbd5553932ba7ae8fa2eec410096ac7685ad44 Mon Sep 17 00:00:00 2001
From: jochen <jschoubben@gmail.com>
Date: Wed, 11 Nov 2026 10:56:55 +0100
Subject: [PATCH 005/243] BLD2: the Go build seat keeps the answer of steps in
 detected-steps by fingerprint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Part of BLD2 (Go module): the state detected-steps asked by the template
state, one key per artifact, answered for the same fingerprint, replaced by a
newer one and by again. The drop of a key and the Node and image modules wait
(drop: question to the lead; the others follow in BLD7 and BLD8).

Builds: design 47 G §326, §414

From 357967308f9ff6add29e00a690edaa94b094e9a3 Mon Sep 17 00:00:00 2001
From: jochen <jschoubben@gmail.com>
Date: Wed, 11 Nov 2026 11:00:52 +0100
Subject: [PATCH 006/243] BLD11: the three build modules take the version from
 the ask as MESH_VERSION; version.numbered is no longer heard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Go compile, the Node tsc/esbuild/npm and the image's buildah bud get the
build argument MESH_VERSION from the version the build ask carries. The late
publish on version.numbered goes (code, tests, the consumes of the Go and
image manifests). The image's label and tag and a program's stamp are open
(question to the lead): the design names no key or symbol.

Builds: design 47 G §349, §370, §413

Subject: [PATCH 007/243] BLD14: a run's input is asked of the verb the asker's
 ask names
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Go build module asks the input verb in the ask (the checker's, the
indexer's mesh-catalog input or the assigner's mesh-wants input) and its
manifest invokes the two seats' verbs. The bus refuses the other accounts
(grants of the contract's callers). The step key keeps the contract's form
<node>.<id>: no asker part is named there (question to the lead).

Builds: design 47 G §125, §206, §338, §354

Subject: [PATCH 008/243] BLD15: the Go build module declares its finding
 stream and hears the keeper's ask
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Part of BLD15: the manifest's stream mesh-build-go-findings (the three
finding events, 7 days, 16 MiB) and the consume of mesh-conditions.findings-asked.
The module's writing of findings through mesh-sdk's finding writer waits for
the writer (the writer's API is an open design question, D-16).

Builds: design 47 G §383, §384, §387

Subject: [PATCH 009/243] BLD7, BLD8: the Node and image build seats serve the
 verb steps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Node answers the type-check as lint always, unit where a package has a test
script and integration where it has test:integration, kept in detected-steps by
fingerprint as the Go module keeps it; the image answers none. The manifests
serve it. The step ask's end (step-ended) of BLD7 and BLD8 waits for BLD3 and
the build-step package of mesh-delivery-sdk.

Builds: design 47 G §22, §307, §326, §328

Subject: [PATCH 011/243] GIT1, GIT2, GIT3, GIT10: the forge module serves the
 seat git's verbs and says its events, retires its acting tools, follows the
 catalog half
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The four share files (index.ts, module.json, guard.test.ts), so they land as one commit.
GIT1: seat.ts serves pull, open-pulls, tags, trees, file, contains, statuses, status, comment, view, note, merge-pull
as tools on the seat, each answering the contract's shape and an error of kind refused, not-found or failed; a comment,
view or note whose act id is held is answered held (note matched by id). merge-pull merges the head the caller names
(its from-G judgements are GIT6, GIT7, GIT9).
GIT2: seatevents.ts says pull-updated, pull-merged, pull-closed, forge-pull, forge-status, forge-delete and repo-writable on
mesh.seat.git.event.<event>; the module's emits drop them.
GIT3: merge.ts, check.ts, the acting tools, the owed watch, the gate's source read and check-gates-merge are gone.
GIT10: catalog.ts follows the seat mesh-catalog (revision, catalog-revision); no write is granted before the first view.

Builds: design 47 G §310, §311, §312, §313, §314, §163, §317, §278, §321, §196

Subject: [PATCH 014/243] GIT6, GIT9: merge-pull merges the head the caller
 names and asks no Approve; it refuses every merge until the first
 registrations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

merge-pull answers its refused-kind (head-moved, unprotected, git-refused, no-registrations); an already merged pull request at
that head is answered performed. The failed-steps refusal (policy-failed) is GIT7, stopped on a design question.
GIT9: registrations.ts learns the first registrations from the seat mesh-catalog's verb registrations at the start and its event
registration-changed; the code artifact needs mesh-delivery-assigner:program.

Builds: design 47 G §38, §129, §314, §95, §96, §130, §353, §432

Subject: [PATCH 015/243] GIT11: the seat git's tag writes
 go/vMAJOR.MINOR.PATCH at the commit a released version was built from
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A tag at that commit is answered performed; at another commit, refused (a tag is never moved). The builder alone calls it:
the bus refuses any other account from the definition's callers.

Builds: design 47 G §370

Subject: [PATCH 016/243] GIT13: the forge module keeps no trusted callers; who
 may call a verb is the seat definition's
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The config value callers, the package seats' list of callers with its watch, and the seat git's caller judgement are gone:
the grants part grants by each definition's callers and the bus refuses the rest.

Builds: design 47 G §68, §127, §313, §321

The base "main" fallbacks of the open-pulls read and the announcer are gone (the indexer's module name and tool went with GIT10).
The manifest's version is MAN1's, written with the fill's source it needs.

 no observer's state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The keeper takes finding-written and finding-cleared from each observer's stream
(`*.finding-written`, `*.finding-cleared`, `*.findings-stated` in consumes); its reads of
every `findings`, the views.findings consumes and the read_findings invokes go.
node-engine's name is a local constant since mesh-sdk's buscompose lost it.

Subject: [PATCH 019/243] NATS2: the bus module plans each sender's sent store,
 256 MiB, 7 days, refusing when full
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The store is made by Keeper.Sends, kept when a verdict asks nothing of it, and a full one says `full`.
Which module sends is NATS3's input (the catalog half); this makes the store.

Builds: design 47 G §59, §137, §344, §477

+## A module's kept data, backed up and restored with its delivery (milestone G)
+
+The keeper takes, on its own account, a restore point of one module's kept data on the bus before the module moves across a
+change of that kept data's `form`, and restores it beside the live data when a want takes the module back (design 47, *A
+module's kept data on the bus*). Its seat verbs, served by the tools and handed to the keeper as requests:
+`mesh-broker.snapshot-kept` (the data as the server's snapshot, the module's consumers' positions and the catch-up tool, in
+one directory under the keeper's state), `mesh-broker.restore-kept` (the live data is snapshotted into a set-aside
+directory under a name of its own and only then removed; the restore point is put in its place and the consumers on other
+streams are set back), `mesh-broker.discard-aside` (only on a call that says why, recorded first) and `mesh-broker.aside`;
+the tool `nats_kept` reads the restore points and the set-aside data from the keeper's state `kept`. The backup holder
+keeps the restore points; it calls these verbs through the seat.
+
 ## Files it does not know
 
 Each directory or archive this module declares says how it treats a file it did not write (ADR 0422, ADR 0416).

Subject: [PATCH 022/243] COND3: the keeper sets its view of an observer from
 what it states
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

findings-stated raises what is new, keeps each pending key unchanged, clears every other
condition of the observer on that node with its reason, clears a pending key past its bound
(bounds state, key time to live), and for an observer held once takes the holder's set and
later events only. The holder lookup is a hook (Keeper.Holder) that COND6 wires from the
catalog; the view is kept in memory until COND2 keeps findings-views.

Subject: [PATCH 023/243] NATS4: the bus module takes and restores a restore
 point of a module's kept data, beside the live data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Verbs snapshot-kept and restore-kept (with aside-only and discard-aside) on the seat mesh-broker, handed to the
keeper; taken over from the join's 0480e16f and c4e88eaa, without the verbs aside and discard-aside and the tool
nats_kept, which no design line gives.

Builds: design 47 G §296, §297, §302, §337, §405

Subject: [PATCH 024/243] COND4: the keeper's ask, resync naming a module,
 findings-unstated and the findings view tool
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

resync writes the hand-act log, says findings-asked for every observer or the one named and
settles what it holds; an observer silent five minutes after an ask (bounds state, key time
to live), its machine not away, is the keeper's finding findings-unstated of scope module,
cleared by its next findings-stated; conditions_findings_views answers each observer and node.
The nodes asked are those heard (the kept list of COND2 is stopped on a question).

Builds: design 47 G §390

Subject: [PATCH 025/243] COND5: the keeper hears a machine away and back from
 the watchman
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

An observer on a machine away is not named in findings-unstated; a machine back has its
observers asked again (mesh-watchdogs machine-away and machine-back in consumes).

Builds: design 47 G §389

Subject: [PATCH 026/243] OBS1 (artifact-store-tools, mesh-healers, mesh-vault,
 mesh-watcher, minio, nfs-server): the finding stream in each manifest
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Each of the six declares the stream <module>-findings (finding-written.*, finding-cleared.*,
findings-stated.*, 7 days, 16 MiB) and consumes mesh-conditions.findings-asked; the manifest
tests that hold consumes say it. The other observers' manifests are written by their own families.

Builds: design 47 G §387, §383

Subject: [PATCH 028/243] NATS3 (part, branch-independent): which module sends,
 and a catalog entry read for the bus module
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Sends reads a claim of a seat whose definition has a verb or an event, or an event of its own; AsksOf reads
an entry's bus-state asks and claims. The follower's branch and the wiring wait on the design's answer.

Builds: design 47 G §344, §433

Subject: [PATCH 029/243] COND6 (partial, not landed): the keeper's sources,
 holder and clears from the catalog half and the assignment half
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The fixed Observers list and the engineModule constant are removed; sources are the modules whose catalog entry declares the
finding events, a module in no branch's revision is cleared (module left the catalog), a stopped module no longer placed is
cleared (module left the node), Keeper.Holder is derived from the entry's claims. The per-branch catalog followers in main.go
wait on a design question (how a part adopts one catalog view per registered branch); the whole integration test is red until then.

Builds: design 47 G §365, §196, §200, §364, §384

Subject: [PATCH 030/243] GIT7, GIT8: the forge module keeps the runner's
 failed required steps and refuses a head by them; git_failed_steps and
 git_failed_steps_drop
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

merge-pull refuses a head at whose fingerprint a run failed a required step (policy-failed, naming run, module, step), from the
module's own state failed-steps kept from step-ended, with the seen keys of every step end and the deletion once no watched
branch's head nor open pull request's head names a commit. The two tools read it with its fill and drop a key after the hand act.

Builds: design 47 G §39, §83, §84, §85, §135, §475, §487, §548

Subject: [PATCH 031/243] GIT12: the forge module's package registry checks a
 publish against the builder's reservation, asked by the package's name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The holder asks the seat mesh-builds' verb reserved with the publish's name and version in place of builder_versions, and stores
only a version reserved for an artifact of the publish's digest; the manifest invokes the verb and takes no builder package.

Builds: design 47 G §381, §478, §504

Subject: [PATCH 032/243] REG1: distribution checks a publish against the
 builder's reservation, asked by the artifact's name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The container image and OCI artifact seats' holder asks the seat mesh-builds' verb reserved in place of builder_versions; the manifest
invokes it and takes no builder package.

Builds: design 47 G §381, §478, §504

Subject: [PATCH 034/243] A-C2: a build module runs the pipeline step kind step
 and says its end on its node (issue 1966)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The runner asks a lint or test step of an artifact as the build seat's accepted kind step, and
hears its end as the seat's step-ended on the node that ran it (ADR 0666 sections 7, 8, 21;
design 47 *The steps and who serves them* line 571 and *Asked on a work queue, ended by an event*
lines 583-590 at hq b229f5c4). The build modules' shared package runs a test step as a check of
its one level, carries the packages whose digest the ask names kept, keeps what it passed and
says the counts; a level with no tests ends nothing to run, a source fault could not run, and a
transport fault or an end that could not be said is handed back unsaid, so the work queue gives
the step again and it ends once under its ask's id. The neutral forms are the domain SDK's
(sdk/buildstep pipelinestep.go, mesh-delivery dc0df1b5); the Go module says the end through the

Subject: [PATCH 035/243] A-C3: gofmt and vet are the lint step's, not the unit
 level's (issue 1966)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Lint is a pipeline step of its own, served by the build seat (ADR 0666 section 7; design 47
*The steps and who serves them* line 571 at hq b229f5c4), so the unit level runs tests alone
and the lint step runs gofmt and go vet, with every tag the files name, over each go.mod
directory of the artifact's module directory; a module directory holding no go.mod has
nothing to lint (prepare finding F12).

Subject: [PATCH 036/243] K1: mesh-build-go reads no kept state of the checker;
 the step ask carries the kept results (issue 1966)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A test step runs only the packages with no kept result for their digest, and the runner makes
that carry in the checker's place (ADR 0666 section 8; design 47 *Carried, not run* line 593 at
hq b229f5c4): the kept results reach the step in its ask (StepRun.kept, mesh-delivery
dc0df1b5), so the module's reads lose mesh-delivery-checker.kept and the lookup of the
checker's kept bucket goes. The carried and kept packages are in the step's end, on its step
key.

Milestone 47/G, research 086 area C (K1).

Subject: [PATCH 037/243] W12.5 (Go): mesh-build-go keeps the store holder's
 refused build and serves kept-artifact (issue 1966)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Builds design 47 *The artifact store's holder takes its own new build even
when its seat is the one broken* (lines ~1811-1830, test 60): a trunk build of
a module claiming oci-artifact-registry that the seat refuses or does not
answer is kept as an object by digest and answered kept (BuildAnswer.Kept);
kept-artifact answers its store and object, refusing a module that claims no
oci-artifact-registry, one not kept here and one under another digest. The
store is the template objects (ADR 0666 §4: a part outside the foundation keeps
its data in ADR 0595's templates; design 47's "old objects form" contradicts
it for a non-foundation part, reported). Whether a module claims the seat is
asked of the seat mesh-catalog's verb module (ADR 0596). Callers are left to
the seat definition and the grants part (ADR 0666 §20). build_go_kept reads the
kept builds, build_go_kept_drop drops one (ADR 0666 §25).

Subject: [PATCH 038/243] W12.5: the three build modules answer kept-artifact
 with the domain SDK's judgement (issue 1966)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Design 47 lines 1888-1906 at b229f5c4 (test 60): the verb sits in every build seat's definition.
Its judgement (what may be kept, the kept builds a node holds, the three refusals) is shared code of
one domain's modules, so it is the domain SDK's (sdk/buildstep KeptArtifact, ADR 0634 §2):
mesh-build-go keeps its store, sweep and tools and drops its own copy of the judgement and its table;
mesh-build-node and mesh-build-image keep no build and answer over none, so a module claiming no
oci-artifact-registry is refused and the holder is answered not kept. Their manifests serve the verb
and invoke seat:mesh-catalog.module, which the judgement asks.

Subject: [PATCH 039/243] The gate keeps one delivery record per milestone's
 delivery on its ledger (milestone 47/G, W11.1)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ADR 0656 §7 and design 47 (The delivery record): the gate asks the bus module for a ledger
`records` (template ledger, capped at 768 MiB) with two types: a record, keyed by its milestone and
its heads, whose operations open it, write its group state, trace, outcomes, nodes away, pinned
revisions and end, and remove it; and a month's list of the records opened, since a bundle cannot
list a ledger's instances. An open of heads already recorded leaves the record as it is, an outcome
applied twice writes nothing, and each open removes the records past the setting record-retention
(90 days by default), naming each revision they pinned. The layout is the gate's own (design 20).

Subject: [PATCH 040/243] The delivery record hears the step events through the
 gate's own consumer (milestone 47/G, W11.2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Design 47 (The delivery record): the outcomes arrive as events through the module's durable
consumer, each applied once and only from its owner's account. A family per step event names the
pattern the manifest consumes, its owner and whether its subject names a node; an event is applied
only when its key names its owner and, for a node's event, its x-node is the node its subject
names. It is taken once its outcome is in every open record holding it (by a member's merge
commit, or by the entry of the record's graph difference), so one the ledger did not take is
offered again; an unreadable one is said and taken. The indexer's take-in.taken is the first
family; each other step's event joins the table with its owner's contract.

From 11daf2f289cdd04552725cdac29d84fae9aa4f3d Mon Sep 17 00:00:00 2001
From: jochen <jschoubben@gmail.com>
Date: Wed, 11 Nov 2026 14:35:57 +0100
Subject: [PATCH 041/243] The switch carries every group in flight into its
 delivery record, once (milestone 47/G, W11.3)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Design 47 (The switch carries today's state in, once): at the gate's start, before any event is
taken, each group in flight becomes a record keyed by its milestone and its heads (the heads its
merge was approved at when merges holds one), with that merge as its group state; a second switch
finds each record there and opens none, so a restart or a delivery of milestone G again after a
revert asks nothing again. From then on every merge the gate hands is written into its record too,
so the record's outcomes are found by its members' merge commits.

Left for W11.17 and W11.14: the merge handed as an owed merge-pull instead of the merges key, the
owed keys carried, and merges and turns no longer declared.

From 30a13c4ebb61e8a0df7dbba23a71a978beb12f78 Mon Sep 17 00:00:00 2001
From: jochen <jschoubben@gmail.com>
Date: Wed, 11 Nov 2026 14:35:58 +0100
Subject: [PATCH 042/243] The gate reads and hears the forge through the seat
 git (milestone 47/G, W11.18)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The gate named the forge module's tools and events and guessed their answers' shape (operator (d), F14).
Its reads now are the seat git's verbs pull, statuses, open-pulls and contains, typed in the seat's
contract, a failed read an error and never none; its forge events are the seat's pull.updated,
pull.merged, pull.closed, forge.pull, forge.status and repo.writable, read into the gate's own forms
in one place (gitseat.go). What the forge would merge now (the base's protection, its conflict word,
whether the merging account writes) has no verb of the seat yet: it stays the one read of the
forge's statuses tool, named as such (mergeStateTool), until the seat carries it.

The bus tests' runtime now serves the gate's ledger, so the two whole-bundle tests that failed
since W11.1 pass again.

From 8a6827dfe24da10788620ac68d5533ae747dfce2 Mon Sep 17 00:00:00 2001

Subject: [PATCH 043/243] The delivery record says pinned, freed,
 heads-replaced and record-ended; it ends once every present node runs its
 entries (milestone 47/G, W11.9)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A node away is named with since when and holds nothing; a node away that wakes adds its
outcomes and is no longer shown away. freed is said before a record past its retention is
removed, so no revision stays pinned by nobody.

Subject: [PATCH 045/243] The gate reads what the forge would merge now from
 the seat git's pull, so it names no forge tool (milestone 47/G, W11.18
 follow-up)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The base's protection and required contexts, the forge's conflict word and the merging

From 00b95f1f6811889c0eee99e4e0ef9cb3cd6b277f Mon Sep 17 00:00:00 2001
From: jochen <jschoubben@gmail.com>
Date: Wed, 11 Nov 2026 14:37:33 +0100
Subject: [PATCH 046/243] Every act owed to the forge is said as the seat's
 event owed under one id and stays on its delivery's or group's state until
 its owed.ended is recorded (milestone 47/G, W11.17a)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

At the gate's start every unanswered act is said again under the same id; an outcome is written into the record that
holds the pull request, then answered; an outcome other than performed is said; the checker's are not the gate's.
Needs the forge bridge's forgemsg owed.ended (feat/47-G-forge).

Subject: [PATCH 048/243] The gate serves the seat mesh-delivery's verb source:
 each repository's trunk branch and head and the revision, read from
 source.main (milestone 47/G, source verb)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A node-engine reads the repositories here to call a reverted build's catch-up tool once per repository, never the
gate's state. Rows in issue 888's test and the bus test, which call the verb over the runtime.

From 64ed69db9b09ad61e94c576e74906aebeb2adc52 Mon Sep 17 00:00:00 2001

Date: Wed, 11 Nov 2026 14:37:37 +0100
Subject: [PATCH 049/243] The gate's groups answers the seat's groups: members
 in merge order, the acts said with their ids and the acts recorded with their
 outcomes, one group alone, and none for a group it does not know (milestone
 47/G, W11.10; F-forge-7, F-forge-8)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The forge bridge reads a group's members and what it owes from here, never from the gate's state. The text form of
the members and composed_gate are gone with the answer of before.

From badfe0d16617be3787dfc28a6d224a4215ab58ec Mon Sep 17 00:00:00 2001

Subject: [PATCH 050/243] The switch says every act the old states owed and
 merges hold under its switched id, so the forge bridge performs only what the
 old bridge did not (milestone 47/G, W11.17d carry)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Every key of owed, and the member merging in every key of merges, is said as owed under
meshdeliveryclient.SwitchedActID(state, key, revision), at every switch, the same act each time. The switch reads
the old states through one reader (OldState). Rows in the switch's test.

Claude-Session: https://claude.ai/code/session_01JG73KEq4zoDfM9WtYpcQgZ

(Joined from dd0c4294.)
Builds: design 47 G §169 (GATE5, GATE6); only the owed carry: the member merging in the old state merges is not carried as a merge act (G §167, §542)

Subject: [PATCH 051/243] A merge the forge made with no record's merge-pull
 opens a forge-made delivery record, said once as its transition with why
 forge-made (milestone 47/G, W11.17e)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The record holds the pull request at its head and has no Approve; the delivery keeps that it was recorded
(forge_recorded). Rows in issue 888's test. The test bridge never performs a switched act: the forge bridge decides.

Subject: [PATCH 052/243] The gate takes owed.ended and take-in.taken from its
 manifest's consumes and names neither the forge bridge nor the indexer in
 code (milestone 47/G, the names move)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The module's own manifest is embedded (package at the module's root); an event the gate hears from another module is
the consumes entry with that event's name after its owner. No new seat, no second publisher on the seat git (the
lead's ruling). Rows in the manifest test, which also reads the gate's sources for those names.

Builds: design 47 G §7, §146 (GATE16); the bridge's name stays in code for the old merge follower (eb131beb left out, G §167, §542)

Subject: [PATCH 053/243] The gate holds no merge for a check: the hold, the
 turns, their stalled line and tools, and check-gates-merge go; the merge
 judges the operator's Approve alone (milestone 47/G, W11.14)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ADR 0661: the check gates the ask, in one place (askWaits); once the Approve covers
the heads (approvedWaits) no verdict, carry, composed check or required status is
judged, an Approve given before a trunk move merges onto the new trunk, and a
failure after the Approve is said once on the pull request and as a stalled line
naming the merge it follows. A check failing before the answer withdraws the ask.

From 8ee28d08c33c8e8e3fe834a4a1205af0f8016954 Mon Sep 17 00:00:00 2001
From: jochen <jschoubben@gmail.com>
Date: Wed, 11 Nov 2026 14:44:17 +0100
Subject: [PATCH 054/243] The gate says its records' ledger filling, full and
 room, and holds a merge whose record finds no room (milestone 47/G, W11.20)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Design 47: a store filling is said before it is full. The gate reads its ledger's fill through the
tool runner's mesh/ledger.fill, says filling of the seat mesh-delivery when a record takes the ledger
past 80 % of its cap, refuses the next record when none fits and says full naming it, and keeps the
merge waiting for room on its delivery (held_full), so a restarted gate judges alike. Once the
ledger is below 80 % again, after the retention's removals, it says room and hands the merge.
gate_records says the fill against its cap, or why it is unread.

Subject: [PATCH 055/243] The gate names the issues linked in the issue tracker
 and the forge's author, and reads no description (milestone 47/G, W11.5)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ADR 0659 §4 kept three description reads that shape words only until they move to the bus: the
issue numbers the ask names, the author a stalled line names and the notice that after: lines are
not read. The ask now names the issues linked to each member's pull request, read once per head
through the seat issue-tracker's list (a tracker that does not answer is said, never waited on);
the author is the forge's pull request record's, from the seat git's events; the after: notice is
gone. The gate's forms of a pull request and a delivery hold no description field.

Subject: [PATCH 056/243] The gate asks the ledger's calls and its fill of its
 machine's tool runner (milestone 47/G, W11.20 ruling)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The gate reads its records' ledger fill before it opens a record; its manifest asked no
capability, so it could run beside a runner answering neither. It now asks ledger-calls and
ledger-fill, the fill a capability of its own.

(Joined from ace22b9f.)
Builds: design 47 G §431 (the reads of the teller's answers and the view's reach are by their events); the commit's calls of teller_answers and view_reach are kept whole, the map names them no line

Subject: [PATCH 063/243] M1-M5: the router holds back the asker's oldest ask
 behind a fourth and offers it again when one ends; the seat
 operator-channel's ask-again offers it now (milestone 47/G, issue 1966)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Claude-Session: https://claude.ai/code/session_01JG73KK8HD1gufnqyFxMFdW

ask-again is the seat operator-channel's verb (key in; state or error out), not the module tool messenger_ask_again, and records no hand act (G §394, §450).
(Joined from 681975ec.)
Builds: design 47 G §40, §83, §403 (RTR1, RTR2)

Subject: [PATCH 070/243] NATS10: the bus module serves no restore point tool
 and keeps no state `kept`
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reverts bbd9f638, c2e017a4 and b6884796; cmd/mesh-nats-snapshot/restore.go is as before them. The manifest test
asserts the claim serves only the reading verbs and the keeper's state is asked, requests, spent.

-## A module's kept data, backed up and restored with its delivery (milestone G)
-
-The keeper takes, on its own account, a restore point of one module's kept data on the bus before the module moves across a
-change of that kept data's `form`, and restores it beside the live data when a want takes the module back (design 47, *A
-module's kept data on the bus*). Its seat verbs, served by the tools and handed to the keeper as requests:
-`mesh-broker.snapshot-kept` (the data as the server's snapshot, the module's consumers' positions and the catch-up tool, in
-one directory under the keeper's state), `mesh-broker.restore-kept` (the live data is snapshotted into a set-aside
-directory under a name of its own and only then removed; the restore point is put in its place and the consumers on other
-streams are set back; with `aside-only` it sets the live data aside and restores nothing, with `discard-aside`, naming data
-set aside, it removes that data on a call that says why, recorded first, and restores nothing). Both are called by the
-holder of `node-backup` on the same node alone. The backup holder
-keeps the restore points; it calls these verbs through the seat.

The gate's source value is the contract's SourceByBranchValue and its key SourceKey(branch); the verb takes an optional
branch and answers branches alone when given none. The whole-module package does not compile on the join for GATE11
(settle) and GATE17 (ledger fill and remove), so the unit suite was run with those five sites stubbed in a scratch edit,
never committed: green apart from the stubbed removal case.

Subject: [PATCH 083/243] GATE17, GATE11: the gate removes a record by the
 runtime's ledger removal and reads the plain fill; settle and its ask
 machinery go
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GATE17: record.go Remove asks buscalls.LedgerRemove, recordfill.go reads buscalls.Fill, the manifest names ledger-upkeep-calls.
GATE11: the verb settle, its ask, EvSettled and the Settle field leave with the merge states.

Builds: design 47 G §587, §431

Subject: [PATCH 084/243] G findings: the view-only modules write their
 reader's findings through mesh-sdk's stdio writer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

nfs-server, minio object-store, claude-code, mesh-watcher, mesh-provisioner and mesh-build-go hand their views reader
views.WriterFindings over views.NewStdioWriter and start it; the removed meshconditionsclient.FindingWriter goes.

Builds: design 47 G §686, §687, §689, A-3, A-16, A-17

Subject: [PATCH 091/243] G findings: the modules with findings of their own
 write them through mesh-sdk's writer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

artifact-store-tools (image-missing, sweep-refused), distribution (program and tools bundle, one writer each over its own
kinds), gitea's package-registry (and the token-refused key the TypeScript bundle watches) and mesh-config keep their
findings open and write and clear them through the generic writer; mesh-vault states its assignments view's. A part of an
id told apart by a ref is in the id (<id>.<ref>), each escaped; the writer starts once Serve has the runtime's channel; the
removed findings helpers and resolved words go.

Builds: design 47 G §686, §687, §689, A-3, A-14, A-16, A-22

From 06ebd7e8cf49addbc0d89649117d352e5fd5c85a Mon Sep 17 00:00:00 2001
From: jochen <jschoubben@gmail.com>
Date: Wed, 11 Nov 2026 22:03:09 +0100
Subject: [PATCH 094/243] G findings: the writers name the ask's subject from
 the contract; the readers take the writer whole
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

WriterConfig.Asked is the generated mesh-conditions contract's SubjectFindingsAsked (A-17), a reader's Findings is the
module's writer itself (A-22, A-26), and mesh-build-go's single manifest ask writes and clears its first-view-unanswered
finding through the writer with the contract's Finding (A-28). mesh-config and mesh-vault's own followers (A-28) are not
yet moved onto a views.Reader: they do not compile at mesh-sdk 24f876a.

Builds: design 47 G §687, §689, A-17, A-22, A-26, A-28

Subject: [PATCH 097/243] G findings: claude-code, mesh-provisioner,
 distribution, mesh-config and gitea declare the writer's three events
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The writer listens to mesh-conditions.findings-asked, so each also consumes it, as the modules that moved before.

Builds: design 47 G A-30, §383, §686

Removes holder, table, approval, ready, onestatus, pullkey, checks, group_merge, the effects, the forge reads, the teller's
and the view's reads, kvOperator, kvPulls, delivery_merge_again and their tests. deliveries, show, groups and stalled answer
the records as kept (stalled: a record open past a day, and an act owed unanswered past 15 minutes, read from the record's
acts); the switch reads the old section deliveries and says approval-carried for each unperformed merges key. The manifest
drops pulls, asks, reads, the forge, teller and view consumes and invokes, and the events group and merged.

Builds: design 47 G §172, §431, §592, §593, §613, A-24, A-35 (G-3, G-9, G-16, G-17, G-20)

-// A pull request the mesh was never asked to check (novox/hq issue 347).
-//
-// The forge's announcer is the only way the mesh hears of a pull request's head, and on 2026-10-09 it missed one: a
-// pull request opened after its push moved nothing the announcer read, and waited unchecked, unable to merge, with
-// nothing saying so. This owner asks the forge itself for every open pull request when it starts and when an event says
-// what the forge shows may have changed — a merge check's status, a new head (events.go), not a poll
-// (novox/hq ADR 0406 §1, issue 975) — and once more at a head's bound, and one whose
-// base requires the merge check — mesh/merge-gate or mesh/repo-check — with neither on its head for UncheckedAfter
-// since this owner first saw it so is said as a delivery held: a `stalled` line in the state Unannounced, which the
-// gate says as a condition (conditions.go) like any other delivery past its bound. The delivery domain's own
-// word, so no second condition and no second judge: the id is the one its delivery will have once announced.
-//
-// A head whose check started and never answered is said the same way (novox/hq issue 438). Counting any merge-check
-// status as checked let a head that got only a pending mesh/merge-gate, or never got mesh/repo-check, wait unable to
-// merge with nothing saying so. So a head is checked only when every merge check its base requires has answered —
-// success, failure, error or warning, a failure being a verdict the pull request shows itself — and one with a
-// required check pending or never set is said once that has lasted the delivery table's bound for a check asked and
-// not answered (Bounds[Proposed]): an announced head would be said after that bound too, and it is longer than the
-// controller lets one check run (its checkTimeout, 45 minutes), so a slow check or a status read a moment behind
-// (issue 423) is never said. Such a head was announced — the controller set its status — so its line is not in the
-// state Unannounced but Unanswered, with words of its own.
-//
-// A head whose delivery is held in ready or rejected is said by the same rule (novox/hq issue 441). Those states have
-// no bound of their own — the verdict is known here — but the forge's status is what lets the pull request merge or
-// shows why not, and a status write that lagged or was lost (issue 423), or a check asked again after the verdict,
-// leaves a required check pending or never set there: the pull request waits on it, and nothing here asks again. So
-// such a head is kept here like one without a delivery, and said on the same bound, as Unanswered — it was announced,

-// and checked wait under bounds of their own, and the rest are past the merge, their pull request no longer open.

Subject: [PATCH 102/243] GATE: the gate's whole-module test opens a record and
 a source key from a take-in.taken, and its test bus declares the template
 states
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The test bus made buckets from the old state section alone, so a template state (deliveries, groups, owed, conditions) was 'not declared'; it now
makes a bucket for each requires entry of the template state under its local name (A-20).

Builds: design 47 G §613, A-20, A-33, A-34 (G-17, G-20)

Subject: [PATCH 103/243] G findings: the held writers of the stdio bundles are
 made once the runtime has its channel

The held writer reads the keys of its state when it is made, so it is made after Serve answers state calls; the keeper says a finding is not said before it exists.

Subject: [PATCH 109/243] G findings: mesh-config's and mesh-vault's owner
 views are followed by the reader (Follow), not adopted: they hear the owner's
 own views event

Adopt subscribes a seat's event with further parts (<seat>.<event>.>), which never matches the plain views event of an owner; the reader's Follow hears it and asks again on a gap. Also the distribution whole test counts its own two events by subject, as the writer's are said beside them.

Builds: design 47 G A-28, A-26, A-30

mesh-delivery-builder.builder_versions answered no numbered version for any name asked (mesh-sdk go and ts, mesh-host, node-tools, mesh-delivery-builder, mesh-conditions), so every module takes 0.1, the floor §368 gives a module with none published: all 144 manifests (141 from "1", distribution, mesh-provisioner and mesh-provisioner-client from "2", which carries nothing over, §583).

claude-code, mesh-build-go, mesh-provisioner and mesh-self-check drop their old state findings and stream <module>-findings for the requires entries findings (state) and finding-events (events: the three finding events, 7 days, 16 MiB); mesh-knowledge gains finding-events and the consume. The manifest forms follow mesh-watcher's. The judge refused each for the old form (§529, §577) or for the missing stream or consume (§387).

Builds: design 47 G §387, §529, §577, A-30

ask-bound-seconds and view-waits-seconds are read by the keeper's own code at its start (settings.go ReadSettings, stdio.Config), so the manifest marks them runtime: true; go.mod requires meshcatalogclient at the zero version, which cmd/mesh-conditions/branches.go imports (the requiredmodules check).

Subject: [PATCH 119/243] LOCKS (A-56): the locks check counts the mesh's own
 @novox/mesh-* packages as it counts the SDK
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A module naming only the mesh's packages beyond typescript and the types needs no lock (gitea names the contracts' git and mesh-catalog packages); a row in the first test fails without the change, as does the catalogue's own run.

Builds: design 47 G A-56, ADR 0469 §5

Subject: [PATCH 120/243] COND7 (the condition's owner): a condition carries
 the finding's owner and waiting-on; a failed head is the operator's two hours
 after its since
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The keeper copies owner and waiting-on from the finding at raising (and into a condition kept from before G at its next
change), hands a pipeline-failed to operator-channel after the setting owner-handover-seconds (default two hours, timed
from the finding's since as a bound with its own time to live), says each change as the change owner, and the tool
conditions_owner sets an owner now, written in the hand-act log.

Builds: design 47 G §540, §685, §678, §557, A-58 (seed-waits: the indexer sets the finding's waiting-on; no kind rule here)

From 72ccb75c1b786f3b1ab4db429fffed6ebbd1b381 Mon Sep 17 00:00:00 2001
From: jochen <jschoubben@gmail.com>
Date: Wed, 11 Nov 2026 22:50:17 +0100
Subject: [PATCH 122/243] COND10 (stated kinds, both subject forms): the keeper
 clears only conditions of the kinds a statement covers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A findings-stated carrying kinds sets the keeper's view of that observer, node and set of kinds, and clears only the
conditions of those kinds it does not name; no kinds covers every kind. The finding events are taken from either form of the
part's finding stream, the observer and node read from the subject.

Builds: design 47 G §580, §529 (A-30), §383, §384

From 265d3b83b2b539ffce539ee9e87157977cd34ee9 Mon Sep 17 00:00:00 2001

Date: Wed, 11 Nov 2026 22:53:09 +0100
Subject: [PATCH 123/243] COND8 (haves and attempts as events): the keeper
 hears what a node runs and the healers' attempts, and reads neither state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The node-engine's composed, running, wait-held and wait-ended make the have the hold compares with the wants; the healers'
attempt-changed makes an attempt, dropped at its until on the keeper's own clock (a bound with its own time to live) or when
removed. The manifest's reads are gone and its consumes gain the five events.

Builds: design 47 G §541, §665, §556, §499, §434

From 22b50c88a9f3985ee27b4df88b56304356a7978b Mon Sep 17 00:00:00 2001
From: jochen <jschoubben@gmail.com>
Date: Wed, 11 Nov 2026 22:54:18 +0100
Subject: [PATCH 124/243] HEAL1 (attempt-changed): the healers say each attempt
 they write, and every attempt kept at their start
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The seat mesh-healers' attempt-changed carries the attempt whole with until (a week from its write), on the subject keyed by
the condition and the attempt, each escaped as a key's name is. The event is the seat definition's; the manifest's emits stays
empty as for healer-acted.

Builds: design 47 G §541, §665

Subject: [PATCH 126/243] HEAL2 (the healers' findings in requires): the
 manifest test holds the state and the stream asked by their templates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The healers' manifest already asks findings (template state) and finding-events (template events, the three finding events,
7 days, 16 MiB) and declares no old stream or findings state, and their writer reaches the state by its local name (built in
76be864b and the join); this adds the test that holds it.

Builds: design 47 G §529, §577, A-30

Subject: [PATCH 129/243] JUDGE: the module tests that read a manifest follow
 the manifests' new forms (version 0.1, findings in requires, the foundation's
 old sections)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

sudo and localization expect version 0.1; distribution and gitea read the old objects and state sections; mesh-build-go, mesh-knowledge, mesh-provisioner and mesh-self-check expect the findings asked in requires and the keeper's ask consumed. Each assertion failed against the changed manifest before it was changed.

Builds: design 47 G §368, §529, §584, A-30

Subject: [PATCH 134/243] K-A1: claude-code asks every question and proposal;
 the router holds the oldest back, the slot keys go
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Recovered from 90d70b83 (feat/47-G-asks).
Builds: design 47 G §40; design 46 §6 Limits, batching, history (no ask hidden or refused for its asker's count)

 and no cancel can overtake it there (the queue offers work again after an error, and a cancel of an ask not yet

Subject: [PATCH 136/243] A-C5: mesh-build-node builds against the latest
 published SDK, the toolchain pins none
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Recovered from cfee5f2d (feat/47-G-buildmods).
Builds: design 47 G §571 (the build writes a mesh package's lock entry from the latest published version), A-56

 requires `npm-package-registry` (provided by gitea, form none: reads are anonymous) and, like the lab module, takes its

Subject: [PATCH 141/243] bus5 B5 (A-107): the keeper's process answers
 mesh-broker's snapshot verbs itself through AnswerSeat
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

snapshot-get, snapshot-restore, snapshot-restore-cancel and snapshot-remove are answered by
the keeper's process with the proved caller; it publishes snapshot-get's chunks and hears
their acks on its own subscription, and acts at once with no hand-over through requests
(the record of a running restore is written before it runs). The tools bundle keeps its
tools, nats_snapshots among them. The protected refusal and the whole test's case (send,
restore in place, removal) stay.

Builds: design 47 G A-107 (G-20-lead-answers), §681

Subject: [PATCH 142/243] bus5 B6 (A-109): snapshot-get's chunks go on a core
 publish to any caller; no grant check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

grantedBy is dropped: any caller of snapshot-get gets the chunks, a protected snapshot never.
The chunks are a transfer on the core bus, published with a core publish and kept on no stream.

Builds: design 47 G A-109 (G-20-lead-answers), §681

Subject: [PATCH 148/243] mesh-recovery: the module, its manifest and its claim
 of the seat mesh-recovery
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Builds: design 47 G §554, §656, §657, §633, §564, §557, A-107, A-115
The seat claimed once for the mesh with every verb of its definition; a process answering them (serves beside bus), a tools bundle, the data item points, the state digests (§567), the findings of §561, the four settings.

+# mesh-recovery
+
+Holds the seat `mesh-recovery` (design 47 G §554): the recovery module takes, sets aside and restores a module's kept
+data on the live bus, one act at a time, each act in the hand-act log, its result said as an event under the act's id.
+Go: one process (`cmd/mesh-recovery`) that answers the seat's verbs itself (A-107, A-115) and a tools bundle
+(`cmd/mesh-recovery-tools`) whose `recovery_*` tools call those verbs and hold no grant of their own (§656).
+
+Its data item `points` holds the restore points and the asides; the digests of the points are on the bus in its state
+`digests` (§567). Its settings are `points-cap`, `points-filling-mark`, `point-keep-days` and `dump-wait-minutes`.

Subject: [PATCH 149/243] mesh-recovery: take a restore point, list the points,
 expire them, one act at a time
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Builds: design 47 G §516, §551, §554, §560, §564, §567, §517
Accept writes the hand-act log first, answers accepted/busy/error at once and writes the act before it answers; take writes each stream under a temporary name, its digests on the bus before ended; the cap is refused before anything is written; expiry never removes the newest point.

Subject: [PATCH 150/243] mesh-recovery: restore, set aside, put an aside back,
 cancel, retry, kept-points, the repair at a start
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Builds: design 47 G §516, §554, §560, §562, §563, §564, §566, §567, §682, §691, A-117
restore says restore-started, waits for the dump, finds the point (or has the backup holder bring it back), checks its digests against the bus, sets the live data aside whole and checked, removes it, restores the point and its consumers, and puts the aside back when a step after the removal fails; cancel ends a waiting act failed/cancelled with the hand act's words; at a start it clears temporary points, puts an aside back and ends a cut-off act failed/stopped.

Builds: design 47 G §516, §554, §656, §682, §691, A-107, A-115
Each acting verb answers one of accepted, busy or error; arguments are read afresh per call and refused when unknown (local-name, from, aside-only, discard-aside) or without why; restore takes exactly one of snapshot and request (request is refused until built); the hand-act log names the proved account and the asker.

Subject: [PATCH 153/243] mesh-recovery: the tools bundle, recovery_ tools
 calling the seat's verbs with the proved asker
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Builds: design 47 G §554, §656, §657, §682
recovery_kept_points reads kept-points; every hand tool (take, restore, retry, aside, discard_aside, restore_aside, cancel, expire_points) is one verb of the seat called with the asker the tool runner proved; the bundle holds no grant of its own.

Subject: [PATCH 154/243] A-125: the bus module imports mesh-sdk's bussnap and
 busarchive, its copies deleted
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The take and restore of one stream is shared code in mesh-sdk; the bus module's keeper, its
nightly dump and its tools import it from there and keep no copy.

Builds: design 47 G §655, A-125

Subject: [PATCH 155/243] A-129: kept-points says the unrestored asides;
 recovery_kept_points answers them as the health check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The module's declared health check names recovery_kept_points: it answers what kept-points
answers with the health answer beside it, unhealthy while an aside only it holds the data of
is listed.

Builds: design 47 G A-129, §554, §657

Subject: [PATCH 157/243] mesh-recovery: the process, on its own account,
 answering the seat's verbs on the live bus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The process reads its broker account, answers the seat mesh-recovery's verbs itself with the
caller the bus proved, takes and restores streams through mesh-sdk's bussnap, keeps the digests
in its state, names a kept data's bus objects from its catalog entry as mesh-sdk names them,
learns the fingerprint a module runs at from the node-engine seat's running and the bus
module's dumps from the backup holders' item events, each read whole at its start, and asks
the backup holder on its node to bring the points directory back. A restore whose
restore-started the bus did not acknowledge reads and sets aside nothing.

Builds: design 47 G §554, §516, §551, §556, §563, §567, §655, A-107, A-112, A-121, A-123, A-126, A-132

From d854f936f95383d62bb0acfe7734d445479f6273 Mon Sep 17 00:00:00 2001
From: jochen <jschoubben@gmail.com>
Date: Thu, 12 Nov 2026 01:40:49 +0100
Subject: [PATCH 158/243] mesh-recovery: points-filling, recovery-waits and
 aside-unrestored through mesh-sdk's finding writer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The module measures its points directory against the fill mark of its cap at its start and
after each act, writes recovery-waits for an act that waits on the dump past its bound and
clears it once the act starts its work or ends, and writes aside-unrestored for each aside
only it holds the data of, cleared once the aside is restored or discarded. The bounds are
the settings points-filling-mark and dump-wait-minutes, read at the start.

Builds: design 47 G §561, §557, §564, §633, A-112, A-130

Subject: [PATCH 159/243] mesh-recovery: its settings' files from templates
 under files/, the tools binary ignored
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The catalogue keeps no file text inline for a new module: each setting's file is a template
under files/, packed by the module's archive artifact. A local build of the tools bundle
leaves a binary the module's ignore file now names.

Builds: design 47 G §633, A-112, A-130

Subject: [PATCH 162/243] Join 9: mesh-vault adopts the licence bindings'
 follower through a views reader, on its one writer (A-134)

The follower main added (issue 1409) used the removed views.FindingWriter: it is adopted by a
views.Reader holding the vault's one finding writer, which the assignments view shares, and hears
claude-licence-manager.binding.changed.<consumer> through the adoption.

Builds: design 47 G A-16, A-28, A-134

Subject: [PATCH 163/243] Join 9: claude-code adopts its licence binding's
 first view through its views reader (A-134)

The manager says binding.changed.<consumer>: the module's views reader hears it by the adoption
and asks the first view (FirstBinding) once its subscription is taken, instead of a subscription
of the exact subject of its own.

Builds: design 47 G A-134

Subject: [PATCH 165/243] mesh-recovery: the hand verb restore takes a keeper's
 snapshot by request
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

An unprotected snapshot is received through snapshot-get into
incoming/<request>, refused before the first chunk past the cap, checked
against its digest before any aside, and restored by the module; a
protected one is verified, the running data set aside and restored in
place by the keeper, waited on by snapshot-restored within
snapshot-restore-wait-minutes, cancelled at the bound. The bus module
sends its chunks with mesh-sdk's form.

Builds: design 47 G §681, §682, A-137, A-138, A-139, A-140

Subject: [PATCH 166/243] mesh-recovery: an act cut off by the process's stop
 ends stopped
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A move or a restart stops the process: from its stop signal every call
is answered an error naming the stop, the running act ends through its
own failure path (an aside put back whole, whatever its context), and
every accepted act not ended ends failed with stopped and its event, so
its caller asks again.

Builds: design 47 G §562, A-141

From bf7d040489acff68f8198cc8ca34d92ff17d9eb3 Mon Sep 17 00:00:00 2001

Subject: [PATCH 168/243] mesh-recovery A-143: the dump wait and the
 snapshot-restored wait are bound keys
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Each wait's bound is a key of the module's state bounds with its own time to
live, dump-wait.<act> and restore-wait.<act>, its expiry heard on the key's
watch, so no timer stays in the process.

Builds: design 47 G A-143, A-77, A-138, §681, §561

Subject: [PATCH 170/243] mesh-recovery: its one whole test against the bus,
 and an act's end said once it is free
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The whole test runs the process on its own account against a bus of its
own, every bound a setting of seconds, with a stand-in bus module for
snapshot-get, snapshot-restore and snapshot-restored: a hand take's log,
a restore waiting on the dump past its bound key, busy and the ask again,
the expiry on its bound key, a keeper's snapshot in three chunks, a
protected restore cancelled at its bound and its aside put back, one the
keeper answers neither, and a stop putting the aside back.

It found that an act said its ending event while it was still the running
one, so a caller told busy that asked again on hearing it was told busy
with the same act and heard nothing more: the act is now released and
written ended before its ending event, and the removal at a snapshot-kept
runs before its ended.

Builds: design 47 G §557, §554, §681, §562, §551, A-138, A-140, A-141, A-143

Subject: [PATCH 175/243] BG9, BN9, BI3: the build seats' steps with drop
 writes the hand-act log first
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A drop of a kept detected-steps key records the act with the caller the bus proved, then deletes the key; a log that
refuses deletes nothing and is answered error; a drop without why is refused; fetch is asked unless drop.

Builds: design 47 G §463, §480

Subject: [PATCH 181/243] BG7, BN7: a fetch naming builds reads each package
 member from the artifact store
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Each member's build is read at /v2/<module>/<artifact>/blobs/<digest> through the required provision artifact-store
(bound to a file), checked against its digest and laid as the package it names: a Go module zip replaced in the temporary
modfile, an npm tarball in node_modules. A mismatch or a store that does not answer fails the step naming the member.

Builds: design 47 G §465, §373, §466 (lead answer A-151)

Subject: [PATCH 194/243] MV1: move contracts and sdk under modules/, importers
 follow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The delivery repository's contracts and SDK live under modules/ as
mesh-delivery-contracts and mesh-delivery-sdk, their Go module paths
renamed to match the folders (the TypeScript names already did), and
every importer in mesh-delivery, mesh-catalog, mesh-host, mesh-tools
and mesh-sdk follows in the same group: a design as it should be, one
path per module, checked by the group's check building every importer.

Builds: design 47 G §427, §88

Subject: [PATCH 195/243] mesh-recovery: the four bound settings take a
 fractional minimum of 0.01, so a whole test sets seconds
MIME-Version: 1.0

A minimum of 1 refused the fractions A-138 allows; 0 stays refused, as the reader refuses it.

Subject: [PATCH 196/243] BG5, BN5, BG6, BN6 (toolchain part):
 toolchain-reported on the seat's subject, with the toolchain program's digest
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The guard's toolchains value carries the sha256 of the go or node program found on the path (read again when the version
changes); toolchain-reported is said on the build seat's subject of the node at start and on each change of version,
recipe or digest; a build's ToolchainUsed names the digest. The legacy toolchain.reported emit and its stream go: nobody
consumes them.

Builds: design 47 G §492, §472, §466 (lead answer A-152)

Subject: [PATCH 197/243] BG8, BN8, BI2: each artifact carries the version the
 ask names
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A Go program is linked with -X main.meshVersion beside main.builtFor, a Node program's package.json version is set, an
image is labelled org.opencontainers.image.version; a build with no version stamps none.

Builds: design 47 G §458, §573

From 9fe3f41ac0aeced17f890b93cd38046118d271f9 Mon Sep 17 00:00:00 2001
From: jochen <jschoubben@gmail.com>
Date: Thu, 12 Nov 2026 05:17:44 +0100
Subject: [PATCH 198/243] AM-K2: the forge module's
 gitea_branch_protection_loosen alone removes a trunk's protection or lets a
 force-push onto it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The tool is marked in the manifest's needs-approval, so each call runs on the operator's Approve; the manifest
uses operator-channel; set_full keeps refusing a force-push onto a trunk and names the new tool; both clients
gain deleteBranchProtection.

Builds: design 46 approval mark §21 (milestone G)

Subject: [PATCH 199/243] SD5, BG11, BLD10: the build modules' shared code
 moves into the delivery SDK
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All of mesh-build-go's buildstep Go module leaves mesh-catalog for
modules/mesh-delivery-sdk: the step run, fetch and release and the
regenerate-and-compare step as the package steprun, the CPU share as
steprun/buildcpu, the conformance kit as steprun/conformance, the seat
generator as seatgen with cmd/seatgen, and cmd/mesh-pack. The three
build modules and the builder's and checker's tests import the SDK and
keep no copy; the SDK requires nothing of mesh-catalog. Code the build
modules share is the delivery domain's SDK, not one module's package.
It carries the build-module round's two new files of that package
(dropdetected.go 247c422f, storedbuilds.go 904b8aed).

Builds: design 47 G §464, §680, §327, §420, §495

-// Package buildcpu is how much of a build node's processors its builds may take, and how they yield to everything else

-// usage never impacts the normal workings of our nodes ... We have 3 build agents so they should share the cpu power").
-//
-// Three parts, each with one owner:
-//
-//   - **Priority.** A build seat's holder (catalogue.Seat.Yields) runs at the lowest priority there is: the composer
-//     gives its runtime process declaration.Yields, and the node-engine places every yielding process of the node in
-//     one slice (declaration.YieldSlice) whose CPU weight is idle, with Nice=19 for every process it starts.
-//     Interactive and service work always comes first; builds take the cycles nothing else wants.
-//   - **One cap per node, shared.** The node's share of its processors is one value, the node-engine's own config
-//     `build-cpu-share` (ShareSetting), set per node through the node's settings layer. The node-engine writes it as the
-//     slice's CPUQuota: one bound the kernel holds for all the node's build modules together, never one per module.
-//   - **Threads.** The quota bounds the total; threads only size each step. A step gets the share divided by its own
-//     module's capacity (Threads), from the share the composer hands as a word (ShareWord): GOMAXPROCS sets every go
-//     command's -p, the compiler's concurrency, a test binary's processors and -parallel. A module given no word sets

-# The conformance kit's captured runner output
-
-Every file here is the real output of a test runner, never written by hand (issue 1901: a fixture that agrees with the
-mistake proves the mistake). The toolchains are the build nodes' own, as `mesh-build-go.build_go_toolchains` and
-`mesh-build-node.build_node_toolchains` reported them on 2026-10-26: go1.27.3-X:nodwarf5 on every build node, node
-v26.12.1 (npm 12.2.1) on shanks, novox and g14, and typescript 5.9.3 from mesh-build-node's toolchain/package.json.
-To capture a case again, make its tiny project in a fresh directory as below and run the command shown; the kit's case
-table (conformance.go) says what each failure must say.
-
-## go/ — `go test -json`
-
-- `passfirst.jsonl` and `subtests.jsonl` (2026-10-26, go1.27.3-X:nodwarf5, for issue 1901's thorough fix): in
-  `/tmp/1901k/go/<case>`, `GOTOOLCHAIN=local GOFLAGS=-mod=mod go test -json -count=1 ./... > ../<case>.jsonl 2>&1`.
-  - passfirst: module `example.com/passfirst`, `go 1.26`. Package `a` has `TestTheFirstPackagePasses` (empty). Package `b`
-    has `TestTheSecondPackagePassesFirst` (empty) and `TestTheSecondPackageFails`, which calls
-    `t.Logf("judged against the seat as it stands")` then `t.Fatalf("the seat has 2 holders, want 1")`: a passing package
-    and a passing test before the failing one.
-  - subtests: module `example.com/subtests`; `TestTheTable` runs `t.Run("passes", func(t *testing.T) {})` and
-    `t.Run("fails", func(t *testing.T) { t.Errorf("got 3 machines, want 4") })`: the parent fails only by its subtest.
-- `subpanic.jsonl` (2026-10-26, go1.27.3-X:nodwarf5, review round 1 of issue 1901's fix), the same way: module
-  `example.com/subpanic`; `TestTable` runs `t.Run("passes", func(t *testing.T) {})` and `t.Run("panics", ...)`, which
-  writes to a nil map. go test -json files the subtest's panic under the parent `TestTable`.
-- `logthenfatal.jsonl`, `panicking`, `timeout`, `deeptimeout`, `buildfail`, `exiting`, `killed`, `passthenfail`,
-  `mainexit`, `race`, `racemain` were captured for issue 1901's first and third meetings (2026-10-23 and 2026-10-25,
-  go1.27.3) in mesh-catalog's mesh-build-go (`testdata/captured/go-test-json-*.jsonl`, named there `go-test-json-pkg-<case>`
-  and `go-test-json-log-then-fatal`) and moved here unchanged. From that README: each is the standard output and error of
-  `go test -json -count=1 ./...` (the timeouts with `-timeout 2s`; race and racemain with `-race`, CGO_ENABLED=1) in a
-  throwaway one-file module that fails without a test's own assertion: panicking (a nil map write in TestPanics), timeout
-  (TestWaitsForever sleeps past the timeout), deeptimeout (two parallel tests and sixty blocked goroutines past the
-  timeout, so the goroutine dump pushes the panic line out of the last 4 KB), buildfail (a type error in a test file),
-  exiting (os.Exit(3) in TestExits), killed (TestKilled sends itself SIGKILL), passthenfail (TestMain panics in a
-  goroutine after m.Run passed), mainexit (TestMain exits 2 after m.Run passed: go test prints "PASS" and then
-  "FAIL <pkg>"), race (TestRacesOnTheSeat writes a package variable from itself and a goroutine), racemain (TestMain does
-  so after m.Run passed). logthenfatal is a test `TestThree` in package `x` that logs a line with t.Logf and then fails
-  with a multi-line t.Fatalf naming three subscriptions.
-
-## node/ — `npm test` running `node --test` under the TAP reporter
-
-Captured 2026-10-26 with node v26.12.1 and npm 12.2.1 (`/usr/bin/node`, `/usr/bin/npm`), in `/tmp/1901k/node/<case>`, the
-way mesh-build-node runs a test script:
-
-    PATH=/usr/bin:$PATH NODE_OPTIONS="--test-reporter=tap --test-reporter-destination=/tmp/1901k/node/<case>.tap" \
-      npm test > ../<case>.stdout 2> ../<case>.stderr
-
-`<case>.tap` is the report file, `<case>.console` the stdout followed by the stderr. Each project's package.json is
-`{"name":"<case>","private":true,"type":"module","scripts":{"test":"node --test --experimental-strip-types 'test/*.test.ts'"}}`
-(the script every TypeScript package of the catalogue and the SDK runs), with these test files:
-
-- two-files: `test/a.test.ts` holds `test('passes in the first file', () => {})`; `test/b.test.ts` holds
-  `test('passes in the second file first', () => {})` and `test('fails in the second file', ...)`, which logs
-  `judged against the seat as it stands` and asserts `assert.strictEqual(1 + 1, 3, 'one plus one is not three')`.
-- suite: `test/a.test.ts` has `describe('the seat', ...)` with `it('passes inside', () => {})` and `it('fails inside', ...)`
-  asserting `assert.deepStrictEqual({ holders: 2 }, { holders: 1 })`.
-- crash: `test/a.test.ts` holds `test('passes before the crash', () => {})`; `test/b.test.ts` holds
-  `test('throws after it returned', ...)`, which throws `new Error('the bus closed under the test')` in a `setTimeout` of
-  1 ms, and `test('waits after the throw', ...)`, which waits 50 ms: node fails the file with an uncaught exception.
-- logcrash (review round 1): `test/a.test.ts` holds `test('passes and logs', ...)`, which logs
-  `retrying after Error: the store was not ready yet`; `test/b.test.ts` is crash's. A passing test's console line
-  holding "Error" comes before the crash's own.
-- timeout: `test/a.test.ts` holds `test('passes before the wait', () => {})` and
-  `test('waits for an answer that never comes', { timeout: 200 }, async () => { await new Promise(() => {}); })`.
-- syntax: `test/a.test.ts` holds `test('passes in the first file', () => {})`; `test/b.test.ts` is
-  `import test from 'node:test';` and `test('never loads', () => {` (cut off): the file does not load.
-
-## tsc/ — the type-check
-
-`typeerror.console` (2026-10-26, typescript 5.9.3 under node v26.12.1): in `/tmp/1901k/tsc/typeerror`, `ok.ts` is
-`export const holders: number = 1;` and `seat.ts` is `import { holders } from './ok.js'; export const name: string = holders;`;
-the command is mesh-build-node's type-check line without a tsconfig.json:
-
-    node <typescript>/bin/tsc --noEmit --module NodeNext --moduleResolution NodeNext --target ES2022 --rootDir . ok.ts seat.ts
-
-and the file is its stdout followed by its stderr.
-
-## passing/ — a runner's words when the network did not answer (novox/hq issue 1748, ADR 0664 §1)
-
-Not captured by running: a network cannot be cut on demand in a test. Each file holds the words a runner wrote when a
-build step met the fault on the mesh (the journal of ace on 2026-11-09 for ssh and go, the forge's sshd penalty; npm's
-error codes and buildah's pull failure as those programs print them), and for each a negative case, a failure of the
-source whose words are never a network's (an unknown revision, a checksum, a missing package, a failed RUN). Name:
-`<runner>-<case>.txt`; the kit's table (conformance.go, PassingCases) says which are transport faults.

From fea509d3f593468fe4df9937ddcc0a8ac02a4c93 Mon Sep 17 00:00:00 2001

Subject: [PATCH 200/243] BKP6: the put-off wait for a restore is a bound key
 of restic's state put-off; its expiry raises backup-waits and ends the wait
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The record backed-up reads is the key `<module>.<item>` of the module's own state put-off (key-ttl), bounded by the setting
put-off-bound (minutes, default 60); the bus removing it is heard as the expiry, which writes the finding backup-waits through
the held writer over the module's findings and ends the wait, so the night never holds its lock without a bound. The file
put-off.json and its writes are gone. The manifest requires put-off, findings and finding-events and hears findings-asked.

Builds: design 47 G §561, §563, §557, §302, A-155, A-77

Subject: [PATCH 202/243] BKP4-BKP6 live path: restic's item events over the
 bus with the night's own broker account; the wait for a restore ends when the
 bound's expiry cancels it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

An integration test starts the night as the node does: its credential is read from where the manifest places it (the process
night's MESH_BROKER_FILE, the module's own-secrets broker), it says each item started and ended on the seat node-backup, gives
way to a restore that runs (items put off as keys of the state put-off, started again on the restored) and, past put-off-bound,
the bus's expiry writes backup-waits into the findings. It found that WaitRestored held a fetch of a minute after its context
ended, so an expiry ended the wait up to a minute late: it now consumes the restored events and ends on the context.

Builds: design 47 G §563, §561, §554, A-150, A-155

Subject: [PATCH 203/243] C3d REG2: distribution keeps no caller list; the
 build modules are the catalog half's claimants of node-build-* seats
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The config `callers`, the tool registry_callers and its invokes, the caller-list code and the holder's per-verb
Allowed checks go. The windows' driver counts as build modules the modules claiming a `node-build-*` seat in the
catalog half, followed by the seat mesh-catalog's branch follower on the program's views reader (one shared events
hub); it wakes again when a build module's entry moves. The retention check of remove finds the artifact sweep's
holder through the seat mesh-module-assigner's holders (seatlist.HolderOf), not a name.

Builds: design 47 G §610, §7, §428, A-156, A-82

 against the seat list and pull the named worker
MIME-Version: 1.0

The runtime source is *steprun.SeatAsks (named worker not bound is said through the module's journal); the callers follow
the seat list (steprun.SeatListCallers).

From bf60d6a8bb1671fa7d9c5b0fbe202e8e2b20d61a Mon Sep 17 00:00:00 2001

Subject: [PATCH 207/243] NATS3 (rest): the bus module plans from the catalog
 half of every watched branch, not from manifest-accepted
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The keeper follows meshcatalogclient's branch follower and the seat list on its views reader, and plans again at each
move of a branch's view, the registrations or the seat list. Each local name is planned from the first of the module's
watched branches in its registration's order; another branch asking it with other settings is said drifted, naming
the branch. A module of the new form whose resolved seat definition has a verb or an event gets its sent store; one
including only parts, and a foundation part, none. A module in no watched branch's newest revision loses its plans
key, its entries orphans. The sum of the caps counts the old sections the entries declare. The manifest consumes the
catalog half's and the seat list's events and invokes their verbs; manifest-accepted and indexer_bus_state go.

Builds: design 47 G §344, §433, §532, §533, §537, §538, §547, §591

Subject: [PATCH 208/243] B7-3: the pinned event's catalog entries name their
 branch, the record keeps it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A catalog revision is pinned by its watched branch and its number (revisions are numbered per branch): PinnedRevision gains
branch, Pin and Free take it, the key names it so two branches' revision 9 are two pins, and pinsOf says {branch, revision}.
Also the C2 merge's sourcetools imports follow the contracts' new path.

Builds: design 47 G §579, A-171

OpenForgeMade is the fill; no path of the gate opens a forge-made record (design 47 G §151 ends the mark from G's delivery),
so the teller says none until one does.

Subject: [PATCH 212/243] C1c-2b: the three build modules keep a run's answer
 in an outputs store and serve the verb output

Each module's puller keeps an answer over what step-ended carries inline in the object store `outputs` its manifest requires
(template objects, 256 MiB) and its tools serve `<seat>.output` from it; the manifest claims the verb.

Builds: design 47 G A-254, A-257

Subject: [PATCH 213/243] Join 11: the merged heads compile where no area's fix
 is owed

The join's importers name the delivery repository's moved contracts and sdk
(MV1), node-tools' tests use mesh-sdk's gate, the duplicate node-engine claim
rule of the reader release gives way to G's, and the assigner names its first
watched branch, never a constant. The seat holders' AnswerSeat callers are
area 6's.

Builds: design 47 G join 11 (merge of fix round 11)

Subject: [PATCH 214/243] Join 11: distribution's holder test is C3d's, which
 its holder code is

The merge of main's holder test (caller list from the config watch) over C3d's
(no caller list, REG2) left cases the merged holder does not answer; the
holder's code is C3d's, so its test is too, with the moved delivery paths.

Builds: design 47 G REG2 (C3d)

Subject: [PATCH 215/243] Area 6 (join 11): every AnswerSeat caller follows a
 seat list and its grant

AnswerSeat checks a call's caller against the seat's definition its caller
reads from the seat list it follows (A-186). The bus module's keeper hands
it the mesh-broker definition its seat list holds once heard; mesh-recovery,
which followed none, follows one over its connection and an event hub, read
again once its events are live, and its manifest and its process invoke
seat-definitions and consume the list's two events. Its whole test answers
the seat list.

Builds: design 47 G lead answers A-179, A-186 (join 11 area 6)

Subject: [PATCH 216/243] Area 4 (join 11): the Go build module lists its kept
 builds through buildstep's bus-free judgement

buildstep no longer takes mesh-sdk's buscalls objects (that package now reaches
the bus): the module judges each object of its kept-builds store with
KeptBuildOf and orders them with SortKept.

Builds: design 47 G (join 11 area 4: buildstep kept free of the bus)

Subject: [PATCH 218/243] Area 5 (join 11): mesh-recovery's and restic's
 finding writers pass their finding-events binding

nats and distribution declare the old stream form and require no finding-events, so their writers stay on it.

Builds: design 47 G A-274 (answers G-22)

The gate consumes pull-updated and invokes open-pulls and pull; it writes deliveries and groups
under their key forms, deletes them as a take-in or a closed pull request leaves them, copies a
delivery's base onto the record's member, answers groups from records and the group key together,
puts a missed event right at its start, and writes switch.done once the switch has run.

Builds: design 47 G §716, A-279, A-236, A-281

Subject: [PATCH 227/243] Join 11: every go.mod requires, at the zero version,
 each mesh module its packages load

The checker's fetch pins only the zero-version requirements a directory's go.mod names
(mesh-build-go workspace.go goModOf), so a module reached only through another, such as
meshhandacts through meshhandactsclient or mesh-delivery-sdk through meshcatalogclient,
was never downloaded and the shut-off load failed (fetch.go:267). The join's merges had
dropped these indirect requirements that the trunk's go.mod files list.

Builds: design 47 G (join 11, the check's fetch of the group's modules)

 operator channel's notify it invokes

Area 2 added seat:operator-channel.notify to the manifest's invokes for the call in main.go,
and the test of the manifest's invokes still listed the old ones, so the unit level failed.

Subject: [PATCH 229/243] Join 11: restic requires and sums nats-server, which
 its tests load through testbus

The check builds with GOPROXY=off, so a module its packages load that go.sum does not hash is looked up in the
checksum database and fails (try 2: verifying nats-server v2.11.17). mesh-sdk testbus, which restic's tests import,
brings nats-server and its four requirements; go.mod and go.sum now name them, as go list -mod=readonly -deps -test
against the group's heads asks (both build tags).

Builds: design 47 G (join 11, the check's shut-off build of the group's modules)

Subject: [PATCH 230/243] Join 11: the fetch's proof loads both build tags and
 holds the tree's go.mod and go.sum to what they load

Try 2 of milestone G failed in go test, verifying nats-server against the checksum database: restic's
integration tests load it through testbus, neither its go.mod nor its go.sum named it, and the fetch's
shut-off load ran untagged, so it never met it. The second failure of this kind (after the join's
dropped zero-version requires), so the guard is held once, where every repository's check passes: each
directory of the checked tree is loaded untagged and with the integration level's tags, and its own
go.mod and go.sum must name every module the loads reach (a mesh module required, no sums; every other
required at the version selected, with both go.sum lines). The fetch fails naming the module and the
line. A sibling laid beside is loaded as before, unjudged.

This guard lands with G, so G's own check still runs today's proof; no harm, the gaps it finds in the
seven repositories are fixed in this join.

Builds: design 47 G (join 11, the check's shut-off build of the group's modules)

Subject: [PATCH 231/243] A-285: the Node fetch packs each of the group's
 packages and places it by name

The fetch takes `group-packages` (a member's repository, commit, ref and the
package's directory there) in place of the single `package` and its tagged form;
it packs each package a module of the tree takes, publishing nothing, and places
it in every module whose package.json names it, the SDK in every module, in place
of the registry's whatever the lock names.

Builds: design 47 G A-284, A-285

 and takes a revision answer whole

gitea imports @novox/mesh-delivery-contracts-mesh-pipeline-runner, so its
package.json names it and the Node fetch places the group's (design 47 G A-285);
the catalog view's revision answer is typed with its revision and entries, which
revisionAnswer already refuses loudly when the holder leaves them out.

Subject: [PATCH 235/243] A-291: the recovery keeper receives snapshot-get's
 chunks through the SDK's one helper

The keeper's hand-made receive (subscribe to the call's chunks, ask, receive in order, acknowledge each) moves into
mesh-sdk's process.Conn.CallChunks; the keeper's answer checks (an answered error, the space it fits, no chunk granted)
run as its accept hook before a chunk is taken.

Builds: design 47 G A-291

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Every TypeScript module of a fetch gets the registry's latest SDK (ADR 0573 §2,
A-284), so the harness's machine named the real registry and 11 tests (9 unit,
11 integration runs) reached the network; with the resolver down they failed.
The harness now serves a registry of the test's own holding one SDK release,
and the userconfig test reads its address from it.

Builds: design 47 G A-284, A-285

Subject: [PATCH 239/243] restic's tool bundle sets no MESH_BROKER_FILE: the
 node's runtime sets it for a tool bundle

The validator refused the manifest: a bundle's env may not set what the runtime gives every tool bundle. The processes
night and awake keep theirs.
