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 capacity this tool cannot read is unknown to it, not 0: the seat says eligible_known false and the node not known.
A key mesh-config holds without a readable value is what the puller reads as 0, and was dropped silently.
Since mesh-sdk #90 a build module ends a left-running key as failed at the moment it notices; counted as finished,
such a step put hours into the medians and the time at capacity. The view takes mesh-sdk's step bound and restart
reason from the SDK it now pins.
The operator's question (how much are the build nodes used, is ace eligible) took six calls over four tools.
build_usage reads it from the bus's states: seats held (have), capacity (mesh-config resolved), pauses, the
build modules' steps by kind with left-running keys, the last hour and day with total and median time and time
at capacity, the running tries, and the backlog the view program reads from the seats' streams. A try now names
the asks it put, and the checker announces its tries readable, so the view tells a try's asks from a check's.
mesh-grants moves to the same mesh-sdk (3203358c), so its shadow user list grants the checker and the builder the
DEAD_LETTERS reads the controller's list will, and the take-over is not blocked by a difference. The checker and the
builder hear DEAD_LETTERS through buildrun.DeadLetterHearing: in the background, again at every reconnect and every ask
waited for while deaf, and keep whether they hear it in their new state hearing, which checker_status and builder_stuck
say as dead_letters. checker_try says that a try ended by the not-taken bound leaves its ask in the stream.
Not done as asked: a module health tool. The catalogue refuses a tool check on a module with no runtime of its own and no
other check beside it (ADR 0227 rule 8, ADR 0366 §1), so the deaf state is said in the status tools and the log.
The waiter moved to mesh-sdk buildrun (fix/734-lost-ask, d96b9fd6), where every asker of the build seats shares it.
The builder hears DEAD_LETTERS for the go, node and image seats and asks a given-up part of a build again at once, with
the seat's words as why, instead of waiting for the check bound. The checker keeps what it does with a lost ask (a try
ends as error, a check is asked again) and its verdict words.
A check ask handed out five times during a bus reload was given up into DEAD_LETTERS and no build node wrote a step for it,
so try-1793017340003993788 stayed running for ever, held one of the four try places, and checker_try of its head kept
answering its id. The checker now hears the copies DEAD_LETTERS keeps of the build seats' given-up asks (an ordered
consumer from its start; the grant is mesh-sdk/mesh-controller DeadLetterReads, branch fix/734-lost-ask) and ends the
step it waits for: a try ends as error saying why, a check is asked again under its claim, up to three times, then fails
as not heard. A try whose ask no node takes within the step bound ends the same way (a check's backlog stays no fault,
ADR 0525 §9). checker_try_end ends a try by hand, freeing its place and stopping its judging.
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.
Review round 1: while an operator's put runs through its steps it owns the want, so the clear said
'the node does not run it' of a node that runs the bus.
A bus whose move only the operator's put may make (ADR 0546 §8) got no want and nothing in the outcome:
nats on novox, running an old-form build, was on no list while the pass cleared its condition and logged
that it had a want again. The bar now names its holding, puts a node without a live want on neither list
(its condition needs the operator: assigner_put), and a neither condition is cleared as 'has a want again'
only when a live want exists.
A check that landed on ace passed with mesh-build-node's integration tests skipped. The build module now leaves such a
package unmet; the checker keeps the passes and asks the levels from the first unmet one with the need named, putting the
ask again under a new id when a node lacking it declines it. Re-pins mesh-sdk feat/890-placement.

The bus node can only take over a list that exists: each pass composes the accounts block with the vault's hashes, seals
it to the key the bus node says in its have, puts it in the part's own object bucket by digest and writes the key with
digest, revision, user count, users left out and which list to follow. take-over is refused, naming why, while no list is
sealed to the bus node's current key or the loaded list does not grant the bus node its read.
Review of fix/1945-takeover-blockers: no responders on the router's record is an error, not 'no record'; an answer whose
record cannot be reached is not closed; an ask that failed to publish is taken back at the router; an error acting on an
answer is logged. Pins mesh-sdk 175a5567.
