The take-in watched the builder's and the indexer's buckets, started a follower
per module that retried on a 30 s timer, and at start took every catalogued
module in alphabetically: on 2026-10-25 a restart took in about 2 modules a
minute, about 190 followers queued behind 16 slots, and every take-in composed
two or three times even with nothing new, so a new build waited 30 minutes and
more for its credential.
Now two durable consumers named mesh-controller-take-in read the indexer's
modules bucket (every module's last trunk value when the consumer is made, then
each write) and the builder's builds bucket (each write), at most 16 keys
unacknowledged each. The bus keeps what is not taken in: the start's look is the
consumers' own catch-up, and a restart costs only what was left unacknowledged.
A batch reads the catalogue once, takes each module in once, and asks the
composer twice: once for its modules' nodes, once for the bus's node with the
grants. A module registered at its trunk whose compositions and grant exist, or
that this process took in at the same trunk, composes nothing; a key delivered
again is taken in whole. A wait for the builder's or indexer's next write is
acknowledged, a wait on a read or a failure refused with a 30 s delay. The
backlog is in status, and a backlog standing still for 5 minutes raises
take-in-stalled. The controller's account is granted the two consumers' acks.
The follower tests go with the followers: twelve tests become three.
Research 072: the take-ins on a bounded pull consumer (milestone 4, done keys
alone) and the start's look composing only what changed (milestone 2).
A node-engine newer than the registered one, or a node asleep on an older
have, made the done test false after the start deleted NODES; the bus's
health check, probes D6 and D7 and healer H3 then expected the stream and
every node's consumer again, raised them urgent and made them anew. Release
6 sends no declaration, so a stream made again helps no node: a gone stream
is retired. The advisory watchdog also reads a consumer whose stream is gone
as gone instead of failing.

The silent mid-tier plan test main changed stays deleted with the plans (ADR 0539); the SDK is pinned to the feat/r6
head that merged mesh-sdk's main, 748c564c, whose hand path tool is now mesh-hand-compose.
Every grant #456 gives was already feat/r6's, by the SDK's names: each conflict takes feat/r6's side, with main's
test of the user list before the switch kept beside feat/r6's, and the duplicate assertion of the digests' bucket
dropped.
With no send left nothing else writes a missed grant, so the take-in of a done key returns it and tries again every
half minute under an urgent condition until it is written. plan-moved and sent go with the plans. The controller's
first-start deletions are said on a granted subject, a node hears only its backup holder, and the operator's account
writes the hand path, an object replaced included (ADR 0539 clauses 2, 7, 10 and 13).
The object store reads an object's metadata and purges its old chunks when it replaces one, so the hand path is
granted the direct and message gets and the purge of each node's object stream; a test on a bus running the composed
user list walks the hand path end to end.
The new controller says its first start's deletions as an event, a node-engine hears only its backup holder, and the
way back right after the switch, a want and a composition written at the terminal, runs on the user list today's
controller composes (ADR 0539 clauses 2, 10 and 13). The operator is the administrator person, the one second
writer ADR 0539 names.
The switch to release 6 is today's controller's last plan, and the bus runs the user list it composes until the new
controller writes one: so the new controller's writes of each node's compositions and their digests, each new
node-engine's reads of its own compositions and wants and its backup holder's verbs and word, and the assigner's read
of the digests must be granted by this controller already (ADR 0539 clauses 2, 6, 9 and 16; the review's A1).
A node away during the switch finds its last declaration on the stream; once every node's have names the
node-engine registered, no node reads one, so the stream and the nodes' consumers on it go, said once, and a raise
leaves them out (ADR 0539 clause 11).
With no plan left to take a done key in, a write of the builder's keys registers the new fingerprint, composes the
module's nodes and the bus's user list, and writes its grant, so the assigner's rules can name it (ADR 0539 clauses
5 and 7). The new controller composes every node at its start, and the controller it replaced at its own
fingerprint, the operator's way back (clause 10); the merge window's, silent sends' and building plans' buckets are
no longer asserted and are deleted once, each said as the event bucket-deleted (clause 13). The assigner may read
the compositions' digests, and a node-engine hears its backup holder's backed-up.
Each act that changed what a node runs now writes that node's compositions, and its wants follow by the assigner's
rules; a bus upgrade composes the bus's machines and answers the want the operator writes, since the assigner never
moves the bus (ADR 0539 clauses 5, 7 and 15). A node-engine may ask its own backup holder before a data module moves.
Every act that sent a declaration now writes compositions instead, by compare-and-set under the lease, and a
module's compositions are kept for its five newest fingerprints and whatever its want or have names (ADR 0539
clauses 1 to 5 and 14). A module the mesh provides itself, which no want can name, rides in the node's own.

A done key the controller never took in holds no manifest, and the store's nightly collector deleted its bare blob:
node-tools', mesh-host's and the forge bridge's keys name blobs that answer 404. Since issue 1933 the take-in refuses such a
key, and nothing built it again. held (in the serving process, HEADs only) lets the builder ask before it reuses a key; a
refused take-in now names every gone archive and says artifacts-gone with the module, key, fingerprint and references.

The controller's readable states, its bucket lists and the composed golden file keep lane C's removal of the
checks-running and plans-building buckets and the build agent's check subjects, and add lane B's grants bucket.
The controller asks no build of anybody (ADR 0501 §5, ADR 0525 clause 6, ADR 0503 §3). Every module of a walk is taken from the
builder's done key; a key not done yet waits, named in the plan, and never fails it.
- C2b/C2c: internal/builder and cmd/mesh-controller's asks go (askABuild, onlyTheBuildersOwn, buildOneAsked, takeIn from an
outcome, buildAgentsOwn, the builder's say and its fallback, the daemon hearing an outcome). The server follows the retired
seats' built subjects only to let go of them, because the installer's carried user list names them.
- C2d: replay, queue, cancel, clear, kill, pause, resume, delivery-check, check-here and merge-gate are refused by name.
- C3: the check queues (CHECKS_READY, CHECKS_OTHER) and their workers, the checks-running and plans-building buckets and
their grants, the build queue and its hold (plans_building.go, queue.go, link/holds.go, builds_nats.go, checks_nats.go).
- C4: merge_gate*.go, the pull request's repo-check path, the Checked event and its layers; a pull request asks the
controller nothing but to tell mesh-config what its head declares.
- C5: the builds bucket is written only by key_takein.
- C10 (help and refusals): the terminal's help lists only what is served.
Integration tests of the plan's tiers, sends, stops and retries now run on a stand-in builder with a done key for every
module (walk_keys_scaffold_integration_test.go); the tests of the asks, the queue, the merge gate and the replays are deleted.

A bundle is built only from its module's directory (ADR 0480 clause 4), so the proxy leaves
examples/ and the controller's internal/broker; the broker keeps no second copy of what the
proxy shares with mesh-sdk. The image and its Dockerfile go, and a test holds that only
build-agent declares one (clause 11).

ADR 0483: the controller keeps a key per plan in its build phase; holders read it and
take no new check while one is there, but for the oldest check past 30 minutes, one
at a time by a let-through key. The queue says why checks wait.
A literal * in a published subject matches the grant's *, so in one shared bucket a node could read every node's files. Each node now
has declaration-files-<node>, which its account reads by name and the controller writes; the sweep judges each bucket against that
node's latest declaration, under the node's lock with the send, and an object the sweep marked is put again by the next send. Putting
that fails send after send raises a condition.
A node that reports file-references gets the digest and size of each file over 64 KiB that may travel so, and the content is put in
the bucket declaration-files before the declaration is sent; others get every content inline. The controller alone writes the
bucket and node-engines read an object by name (the four grants the node-engine's own fetch makes, no list, no write). An object
goes a day after no node's latest declaration names it. The near-limit condition warns at 75 percent, and a test holds the control
node's declaration, in the reference form, under half the bus's largest message.
