The flag that made the first watch the start's look was cleared after every
watch, even one that failed to open or ended before its Caught mark: the next
watch then handed every standing assignment as fresh, about 300 settles at once
with a catalogue read each, or dropped the keys the cut watch had handed. The
flag is now cleared by the start's look itself, and a watch cut before it opens
the next with nothing heard. Two rows of the existing table test cover it.
Research 072: the grants piece (memberships and credentials heard from placement).
The assign act and the assignments' watch both checked whether an account was
minted and then minted it, and minting overwrites the hash: interleaved, the
bus kept one caller's hash and the node was sealed the other's password, the
crash loop this branch fixes. Both now mint through one statement that inserts
the row only when none stands; the caller whose insert wins seals, the other
seals nothing. issueMissingProcessAccounts mints the same way.
A watch opened again after one ended handed the standing assignments as the
start's look, so one that came to stand in the gap got no bus composition or
grant when its account already stood: only the process's first watch is the
start's look now. The start's look reads the catalogue once and ends with one
composition of the bus's node and the grants; a controller not holding the
lease is told so and tries again rather than dropping the key.
Tests folded to stay within the budget: the assignment tests are three table
tests, the process account and mayIssue tests folded into one of them, and
the concurrent mint is a case of the inventory's rotation test.
Research 072: the grants piece (memberships and credentials heard from placement).
ADR 0539 clause 7 issues a module's credential and grant only when its build is done.
A module built long before and assigned to one more node never has a build done again:
on 2026-10-25 at 17:19 mesh-build-node and mesh-build-go were assigned to ace and composed
for it, the bus's user list never named ace's accounts, and both runtimes restarted every
5 s (one with no credential, one refused by the bus). The assign act composes the assigned
node alone, never the node holding the bus, and writes no grant.
So a write of the assignments bucket is the event: when a key comes to stand (new, or
ended or pending before), the lease holder issues the module's accounts on that node that
are not minted (never re-issued), composes the node holding the bus and writes the grants,
through the composer the done keys' take-ins use. A rewrite of a standing assignment does
nothing; the start's look settles every standing one, one after another. A step of
research 072's grants (memberships and credentials heard from placement).

A success cleared the condition only when the same follower had raised it, so
one raised before a restart or by another follower stayed open after the take-in
worked, and the operator read that a build needed a look. Clearing a condition
that is not open costs one read. On an error return, serve now ends its
goroutines before the keeper closes and before handActConn and the bus are put
back (the review of fix 12).
inBackground ran the take-ins of done keys (now in #463's slots), the start's
look, the given values' replacement and the announced reads beside serve without
serve waiting for them: a take-in could outlive its controller as the loops did.
It now takes the context and is counted in its serving group as well, and a
serve that is stopping starts none.
Thirty urgent fingerprint-not-composed conditions were live on 2026-10-25, each a
done key's take-in a stop or a restart cut with "context canceled". A
cancellation is no fault of the build, the chain or the bucket: a take-in or a
layout whose controller stops returns and the next one does it; one whose own
step was cancelled is tried again without a condition; a send cut by a
cancellation counts as no failure to put its files.
The put test now starts and leaves the node's failure count at nothing, so a
second run of it (-count=2) finds no count left by the first.
The try of the on-change mirror failed with every test passed: goroutines a
served test started outlived its serve and met the next test's globals and its
closed stores. Under -race the served tests show it as a race on conditionsFrom
(watchTheMesh writing it while settlingPending, already running, read it), and
a take-in cut by the stop raised fingerprint-not-composed, a kind with no plain
words, which fails the package after its PASS line.
- serve counts every goroutine it and its parts start (serving_group.go) and
ends and waits for them before anything else is undone: the lease's watch,
the pending settler, the status summary, the facts, the mirrors and the new
declared-packages keeper with its two bucket watches, the declaration sweep,
the read-call counter, the watches' closers, the have watches, the vault move
on a report, and the watchdogs, doctor, healers and asker under their own
group.
- The condition store opens before anything that reads conditionsFrom starts;
askerFrom is an atomic pointer, read from the keeper's goroutines.
- A done key's take-in cut by the stop raises nothing, and fingerprint-not-composed
has plain words.
The mirror composed every node in full on the record mirrors' 10 s tick; a
pass takes about 45 s on the control node, so the controller never rested
(130-175 % CPU, issue 1945 note 22). It now passes on a watch of the
compositions' digests and of the assignments, one pass at a time with the
wakes of a pass coalesced into one after it (at least 30 s apart), skips the
composition when the stores' Input digest is unchanged, and keeps a safety
pass every 10 minutes that composes nothing when nothing changed.
At 16:07:36 the builder rewrote about 120 done keys at once. Each woke a
take-in of its own with no limit, and each take-in read the rest of the
mesh through restOfTheMeshOf, which opened a licences and an identity
pool per call. novox's store ran out of connections at 16:08 and refused
everyone, the controller's retries keeping it full.
- The serving controller lends its stores by inventory (shareStores);
restOfTheMeshOf reads on them instead of opening pools per call, and a
verb run as its own process still opens its own. stores opens each
store once under a lock, since readers now share it. serve uses the
shared identity store instead of a second pool.
- The watch's take-ins and the start's look share one cap of 16 take-ins
at once (takeInSlots); a take-in waiting for its next try holds none.
- store.Ready backs off on a full store (SQLSTATE 53300), doubling its
wait up to 5 s, and says once that the store is full.
Issues 1945 and 1277.
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.
A catalogue merge that leaves a module's sources alone registers it at the new
commit from the same done key, whose build record stands at its first commit,
so the commit had no build and the module no fingerprint of the new form: it
went into the node's own composition while its want named its own, and every
node declared its files twice. currentFingerprints now reads the indexer's
trunk value at the commit when no build points at it (1945/AC15), and a module
a want or have names by its own composition is left out of the node's own
(1945/AC16).
readNode sets ReadsModules, since release 6 composes only for node-engines that read a module per resource (issue 1145);
the failure says the bytes on its first line, the one the verdict keeps (issue 1921).
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.
The served mark in the environment made every later test in the process read as the serving controller's: the
registration test was refused as "never through a verb". The fixture now restores the mark, the hand-act log's
connection, the keeper, the status and the event publishers serve sets.
serve marks the process as handing over once it stops, and refuses every verb from then on; the served tests run it in
the test process, so the connection test's conditions verb was refused without its own process ever starting.
runLine runs the controller's dispatch in the test process, which names every later connection after the line's verb:
the proposals tests left "mesh-controller verb settings", and the conditions verb's test later in the same process
read that name instead of its own.
A merge the controller hears is now kept in the bucket of the merges (ADR 0539 §17); the test that sends one passed
only when an earlier test on the shared bus had made that bucket.
The first want at the switch skips the record hold only where it changes nothing on the node. A slice differing only in
the bus's user list is marked user-list-only, so no yes waits on it at the switch; any other change at the same
fingerprint is judged as any move, against the declaration's digest.
Its want names a composition (ADR 0539 clauses 1 and 6), so a module whose needs others meet must still have one at
its fingerprint, or no want could ever be written for it. Found by the served test.
Assignments and builds live on the bus (ADR 0408), so a fixture written before the chain was attached was not what
the serving controller read; and push, which the row test used, went with the plans.
