Deletes the placement and candidate writes, the reread tool and its forge reads, the two buckets and the placement-changed event.
D1a and D1b are one commit: the index package, the named reads, the tools and the manifest do not compile apart.
Asking whether the merge contains the held commit refused forward merges
forever on a diverged or rewritten main or a squash-merged registered head,
failed every later merge when the forge no longer had the held commit, and
cost one forge call per held commit. The question is now the reverse: a merge
is kept back only when it is in the taken merge and differs from it. A merged
message asks it once, before it writes anything, and a late message writes no
module, deletion, placement or taken key. A take-in asks it once for its
module. A 404 is not known to be older and is written, and said; any other
failure to say leaves the message for redelivery.
The indexer wrote mesh-catalog's merge 9cdac09a back over the later 69056948,
rolling kernel and mesh-build-image back on the nodes: a merged message's
commit was written whatever the held one was. Before writing or deleting a
module's value, the indexer now asks the forge whether the merge contains the
held commit, keeps the held value when it does not and says so, and leaves the
message for redelivery when the forge cannot say. Each applied merged message
is said in one line with the modules written.
No tool showed what the indexer heard of FORGE nor a modules key's history
with times, so the cause could not be proven: the indexer now records each
FORGE message it handles (sequence, deliveries, times, commit, outcome) in its
state heard, read by indexer_heard, and indexer_module_history reads
modules.<module>'s kept values with their times.
Quick fix (Src order in writeOverlay) rejected: Src is 0 once the source moved
on, as here. Thorough fix chosen: the order is the forge's, on every path that
writes a module (merged message, take-in).
A merge whose merged message never reached the indexer had no recovery: take-in answered
held for mesh-vault, whose record stayed at 78d7ef7 after mesh-catalog#535.
A drained forge stream does not say a merge was applied: the forge bridge was still
retrying mesh-catalog#535's merged message when the indexer started, and the source's
head moved taken.mesh-catalog to 9fd9569, so the view and show said the merge was on the
machines while mesh-vault's record stood at 78d7ef7 (ADR 0556 clause 1).
One commit for the branch feat/1126-nodes-compose of mesh-delivery: its 16 commits squashed so its history does not carry the 17.8 MB compiled mesh-delivery-assigner a commit added by mistake and a later one removed (issue 1577). The tree equals the former head ff6c038d. The operator allowed this rewrite of the feature branch on 2026-10-26.
A delivery restarted the checker and the builder before the grants part created their new state hearing;
OptionalBucket answered nil and the hearing was never kept. They, and the builder's reasks and queues and the
indexer's takeins, now open their own states through mesh-sdk process.AwaitBucket (mesh-sdk
fix/1790-state-appears d515c71), which binds on the bus's STREAM.CREATED advisory and writes the latest kept
value. mesh-grants takes the same SDK, whose composer grants that advisory.
A registered module whose repository the forge answered 404 (car-hunter, snake, before the forge's account could read
them) was read again only when the indexer started again or the controller wrote a new build record of it, so the grants
part's composed user list stayed short of their subjects and the take-over was refused. A failed read now keeps the
module as unread, read again on the next source revision and the next merged message (no timer of its own), and the new
tool indexer_take_in (the tools bundle mesh-delivery-indexer-tools, through the indexer's takeins state, as the
builder's builder_ask_again) takes one in now and answers what it stored or why not.

The open helpers were copied into seven parts; code shared between
modules lives in mesh-sdk, so they are mesh-sdk process's now and the
parts are pinned at fix/1945-optional-buckets (e0d1de04), moved to its
main once it merges, one delivery group with mesh-sdk.
Met twice on 2026-10-25: the builder of #48 exited on a refused read of
the gate's source and crash-looped, and its new reasks bucket would have
done the same. A grant reaches the bus with a delivery, so a refusal or a
timeout at start is often only a grant not there yet; exiting for it
stopped the whole part until a hand step on the bus.
Every startup open in the parts is now essential or optional. Essential
ones (a part's own state and the input it exists for) still stop the
start, with an error naming the bucket and its grant. Optional ones are
said and left: watches the bus refuses too. The builder builds trunk keys
without the gate's source, which it opens again at the next candidate
that asks a trunk head; toolchains and previews open again at their next
event, as a missing bucket did. builder_ask_again says that asking a
running step again builds it twice.

The test predates the fix that keeps a held fingerprint while builders disagree (#47, 3e7f852) and still asserted the
blanking that fix removed, so it fails on main 4efe6cf as well. It now asserts the fingerprint is kept after n2's
assignment, and that a merge moving avahi during the disagreement gets none until the builders agree.
The operator, 2026-10-25: only if a module has a new version in commit x is a new value written naming commit x. A merge
wrote every module of the repository at the new commit, fingerprint unchanged (about 186 keys per mesh-catalog merge), and
the controller's take-in took each in again: twice tonight it flooded. Now a merge that gives a module the value it holds
but for the commit writes nothing, and the value keeps the commit its fingerprint first appeared at. The kind: a write
that differs only in where it was computed. The other instance, a source revision re-stamping Src on every module at its
repository's head after any merge anywhere, now stamps Src once. The trunk head stays the gate's source.main.

On 2026-10-25 20:56 assigning mesh-build-node to ace again brought ace's report of 2026-10-23 (v26.12.0) back into the
agreement before the module ran there; the indexer blanked every module's fingerprint to "builders disagree" and the
controller's take-in refused modules already computed and built.
- The toolchain gate (indexer, builder, checker; still one file in three) leaves a report out, said once, until its node
writes it since its current assignment: the assignment's own time, or the revision that opened it.
- The indexer keeps a module's held fingerprint while a language has no agreed toolchain, when its kept inputs with the
toolchains it was computed with give it again; only a new fingerprint (a merge, a base, an agreed toolchain moved)
needs the agreement.
mesh-build-node was unassigned from ace on 2026-10-23 and its ace.typescript key stayed in
mesh-build-node_toolchains at v26.12.0: nothing deletes it, so the indexer, the builder and the
checker took it for a builder and every Node fingerprint said 'builders disagree'. The three now
read mesh-controller_assignments and pass a toolchain report on only while its build module has an
open assignment on its node; builders that run different versions still disagree.
I1: a merge writes each module its manifests name, at its directory. I2: a pull request's changed directory, a
preview's touched module and a source revision's modules come from the modules bucket (a module a pull request adds is
found in the preview by its manifest). I4: the value of today's form (fp, none) is no longer written, since it was
computed from the build records; mesh-sdk keeps it readable until R4g. One commit: the three share applyMerged and its
tests. Pins mesh-sdk feat/r4e-sdk 9cb4d59.
