Re-review of fix/lost-check: writing an empty list at the end kept one key
for every verdict key ever checked. Tests: every row of the lost-ask table
proves the key gone at the end; one row more (deaf after its build module
replaced it, asked again by hand); counts unchanged.
Since 9db9499 the checker asks no check while no node record is on the bus; the bed wrote none, so eight integration tests failed on main (PR #101's check). The fake build module now records the names an ask carries, and the first test asserts n1 is named.
Review of fix/lost-check: an ask no node took yet has no step key, so
asking again then would run the check twice (issue 1791's kind). The
checker keeps the asks each running check put in a new state asks, and the
tool refuses unless every one of them has a step key. Asking again under the
same ask id is not done: the stream drops a second put of an id within its
de-duplication window and keeps both past it, so the waiting copy is never
replaced.
Tests: the hand row of the lost-ask table refuses while its ask waits;
counts unchanged.
The checker's HeardEnds moved to mesh-sdk buildrun (fix/lost-check,
6aeb401): both modules pin it, and the builder, which waits on the same
Asker, now reads an ask's step at each step end of its build module too.
checker_ask_again and checker_status's lost stay in the checker.
Tests: one row in the builder's ask table (its watch deaf, read at a
nudge, done with no new ask); counts unchanged.
mesh-catalog #553's verdict stayed running after its step mvsgthyjed5786
passed on shanks at 19:09:31Z: the watch of that one step key, opened at
18:46:05Z, heard neither its start nor its end and never closed, so the
wait had no bound running and nothing would ever judge it.
- HeardEnds stands between the asker and each ask's watch: at every step
end of the same build module (one watch per steps state), at a
reconnect, the asks waited on read their keys now and are judged; a
watch that closes is opened again, at most 3 times.
- A step the build module's next process ended (RestartReason, a delivery
replacing it) counts as a lost ask: asked again under the claim, at most
LostAskTries, then failed as not heard, judged again when the nodes change.
- checker_ask_again {group, why} ends a running verdict as asked again by
hand; the checker hears its verdicts, ends the wait and claims it anew.
Refused while a step of its pull requests runs, or for a verdict that
is not running.
- checker_status names such checks under lost, and each step's what.
Tests: one table replaces the given-up test (rows for given up, replaced,
deaf and nudged, deaf and asked by hand); counts unchanged (147 unit, 10
integration in the checker).
A repository never merged through the gate has no entry in source.main, so its pull requests were dropped without a log
line, a verdict or a status, and checker_status counted them as new. Now the verdict says it cannot be judged and why,
the forge status is error with those words, checker_status names it under cannot_be_judged, the log says it once per
head, and the heads are judged whole once the trunk head is known. Quick fix: this. Thorough fix (the gate seeding
source.main from the pull message's base head) is still to do: it needs mesh-sdk, the forge bridge and the gate.

A build module's capacity.<node> now carries its node's build window (the operator, 2026-10-26: g14
builds only from 18:00 to 06:00); the seat shows it, outside it says it takes nothing new, and a
value the module cannot read shows as any hour with the value and why. The checker's and the view's
SDK pin moves to mesh-sdk d00dac1.
Only tries a build node holds count toward the 4 at once; tries waiting for a node are bounded
apart at 8, and the refusal names both counts (issue 1890: at 19:53 four tries queued behind 44
checks for up to 47 minutes refused every further try).
The checker wrote a try's asks only at its end, so a 31-minute try could not be told queued from
running (issue 1890). The try's record now names each ask as it is put, then the node that took
it, its state and the phase its step says, written on the step key's own changes. build_usage
names a running try's asks and takes a build module's capacity.<node> (configured bounded by its
node's build CPU, issue 1806's follow-up) when it is current with mesh-config.
A failed test with no cause, or a passing line as its cause, was worded as if it were the failure: a try of mesh-catalog
failed with a passing '✔' line of the first test file. Under mesh-sdk's failure contract the verdict's words and its
status line now start with 'the build module hid the failure (<module> at <version>)', and the check still fails.
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.
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 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.
