Why: the assigner switches its grants source when the controller's lease is handed away; until then the written keys are compared with the controller's, so the switch rests on a measured equality. Needs the group's mesh-sdk pin (PartGrantKey) before it builds.
mesh/check checking e7888024a826 on 769815ac0fea | novox/mesh-delivery#103 in group fix/lost-check
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).

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.
mesh/check being carried to 726bbf1f1ffa on 2ac146078f47 | from e753009fbc71
The view remembered a reach value, a reached head and a motion event as written or said before the bus took them; a write refused at its start (no responders) was never made again while the derivation stayed the same, and mesh-delivery.show said mesh-delivery-view not running on shanks while node_haves said it running.
Quick fix: forget only the refused reach write. Thorough fix, chosen: every write and event the view makes after its lock (reach, reached head, delivered revision, motion) answers its error, and the model forgets what was refused, so the next change it takes in makes it again; one place, the writer of the state both mesh-delivery.show and knowledge-base.progress read.
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.
