jschoubben 6cbdb3712e Judgements and refused setuid searches, which any caller may ask, roll in one bounded key of the node's and add no key to the bucket every node shares; a key per act is kept for hand-overs, access acts and searches started (issue 774, ADR 0563 §2; rev-l3 round 2) 2026-10-28 20:35:33 +01:00

jschoubben 81fa009bf4 The node seat's acts and the engine's own asks are the node-engine's declared state acts on the bus: one key each under its own node's keys, written by compare-and-set, one ask open per path made by a create; acts reads one by its id (issue 774, ADR 0563 §2, §3) 2026-10-28 20:35:33 +01:00

jschoubben 2fe9d678fc Node agent: answer a proposal's candidate keys and follow the seat's placement, not the indexer's groups (issue 1126)
The answer names its proposal and the revision of the node's own candidate key; a node with no key in a proposal is not asked. The watch for its own placement key is tried again until the seat's state exists, so the node switches when its key is written.

jschoubben cd1d2ff447 A read the bus did not answer is tried again after a bound, never kept as an answer: the shadow's answer, the node's composition and the own-secret step (issue 1126)
Met twice on 2026-10-28: shanks kept 'want.shanks.brother could not be read ... no
responders' as the own-secret step's last word, and ace kept 'the vault's own: not yet
... no responders' as its answer to seed-7, each until another input moved. Every bus
read of the composer (manifests, builds, archives, served values, the vault's own and
credentials, the have of what runs) is noted (BusFailed); an answer or a pass that met
one is made again after a growing bound (5 s to 5 min), and a pass is not handed when
the have of its sealed values did not answer. The own-secret step tells a read or an
ask that did not answer (Retry, taken again) from a key absent or the vault's word.

jschoubben a7cd0a7807 Node shadow: reuse a running seal only at its own slot, lay values as the controller does, answer the newest candidate first and say how it goes (issue 1126, C1 C2, T1 T2 T3)
A box is reused by slot (resource, field) after the composition, from what runs or the
have's slots; a have written before slots is reused within its module alone. Config
values are laid by mesh-sdk's one rule (never a default). The shadow answers the
newest candidate first and hands each answer as it lands, says when an answer starts,
every minute what it waits on, and when it ends, and fits an answer to the node's key.
Needs mesh-sdk fix/1126-seed-same (16b8d8a1).

jschoubben 4993f1b1d7 Make the switch between composers safe: a composer tells only its own run's agent, a pass whose run ended refuses nothing, a bus that pauses is tried again, a mark keeps what runs and clears at the next start; pin mesh-sdk 7359d18 (issue 1126)
Live 2026-10-28: the own run's last pass, failing on its run's end, marked
every module of the controller-mode agent that replaced it (ace 60, shanks 63),
and the marks dropped the build and digest because the have read failed in the
bus's reload pause. Now: the refusal hook is bound to the run's agent and ctx;
a pass whose context ended returns nothing; JetStream not enabled or no
responders are tried again after 1, 2 and 4 s before any mark; NotComposed reads
the have again while the bus does not answer and marks nothing it cannot read;
baseline takes a have a composer marked as what runs, so a mark it did not make
clears; each run's shadow lives with the run.

jschoubben 4e8fdfdf04 The way back: a node whose placement key is deleted returns to the controller's compositions without a restart, says so in its journal and its have, and answers such a candidate as returning; pin mesh-sdk 472d5f3 (issue 1126, the seed's revert)
The seed's revert (mesh-catalog #526) was refused on 'would stop running node',
while a self-composing node would have refused its placement's absence, kept
what runs and marked every have failed until a restart. endWhenUnplaced ends the
agent's run when the key goes, so it begins again on the controller's
compositions, as at a start without a key; the composer refuses nothing while
unplaced; the node's have says whose compositions it applies (Composes); the
shadow answers a deleted placement Returns, verdict same.

mesh/check checking b225c7bb4cf5 on be94d2689e2f | novox/mesh-host#150 in group fix/1496-start-health
On ace, 2026-10-26 21:19, mesh-build-node's cache directory was there before the
mesh and used as found. The health statement says such a directory unhealthy, and
the have folded it into the module's health as failed, with no words, while the
module's own check answered healthy; the assigner read it as its canary failing
and held the version on all four nodes.

The directory waits for the operator's hand-over and keeps its own condition,
raised from the same statement; it no longer counts in the module's have. A have
whose health is failed or waits and whose apply said nothing carries the words of
the resource that made it so, so the next one is readable.

On the bus node the bus module has no want and has left the declaration, so no
pass of this engine held its fact and the follower's user list was kept in
memory and never written: the vault and the grants part read no hashes and no
key. A module's user list now reaches its key on every pass, merged into what
the key says with every other field kept; a missing key is said once, never
made up (ADR 0547 §8).

jschoubben 882e75c954 The bus node follows the grants part's sealed user list from take-over, the controller's otherwise, never both (ADR 0547 clauses 7, 8; issue 1945)
On the node whose compositions carry the bus's list, the engine also watches mesh-grants' key user-list.sealed. While it
says follow grants, the object it names is read by name, opened with this machine's sealing key, checked against the
key's digest and the guard, and written to the same file at 0600 only when its digest differs; the bus reloads it
itself. The have says which list is followed and this machine's sealing key, which the grants part seals to.
The follower's test waits for its watch to catch up before a later put, which raced under load. Pins mesh-sdk 175a5567.

The bus node's engine writes the bus user list (ADR 0547 bridge); each write makes the bus reload its accounts, and
for about three seconds every JetStream request meets no responders. An apply that failed then was kept failed until a
key changed (mesh-vault on novox, 2026-10-25 23:04:24), holding every module that needs the secret seat. A transient
bus failure is now retried with a backoff (2 s, 5 s, 15 s, 60 s, then every 5 min), the have saying retrying meanwhile;
after the engine writes the user list, the transiently failed modules are tried again once the reload is over. A have
write that met it is written again the same way. shorten keeps the head and the tail, the cause.

jschoubben 3f02bd7ff6 The bus node writes the bus's user list alone from the newest composition of the bus module, with no want, and says it in the bus module's have (ADR 0547 §8, issue 1945)
The list reached the bus only through a want of the bus module, which nobody writes (ADR 0539 §15): on 2026-10-25 it
stood from 11:23 to 20:50 and was put back by hand. The node agent now follows its composition bucket for the newest
signed composition carrying the user list, writes that file alone through the apply's file step when it differs
(mode 0600, read back, recorded as the module's), moves nothing that reads it (the bus module's entrypoint reloads the
server in place), never goes back to an older list, looks again after every apply of the bus module, and says source,
revision, wanted and written digests, users and any error in the bus module's have (mesh-sdk UserListWritten).

Read with mesh-delivery-view.node_haves (module nats); the bus's own nats_user_can says in_force once it reloaded.

The facts look inside an apply runs while the module is still applying and judges nothing; the
running write then left xorg running and unknown until the five-minute statement, holding every
x11-display consumer behind it. The running write now nudges the health loop, which looks and says
at once. A declaration's report gets the same motion and composition check, and a removed module
leaves nothing marked unjudged (review of fix 15).

A have said applying and failed for the controller on novox at 15:27:36, from a look at the
container being replaced, two seconds before its launch said healthy; the assigner held the
canary on it and set novox back. A look now judges only a module that is not in motion, and a
module whose composition moved carries unknown until a look after the move.
