jschoubben d54eab4052 Never keep a want back for an unhealthy provider, nor a first want for the canary where nothing runs: the module is wanted and its provider down is said (issue 1960)

On novox on 2026-10-29 the assigner wrote no want for de-spiegel and link2pay (rule 5: no provider of route runs
healthy) nor photos (rule 5: no provider of s3-bucket), and none where no node of a module was online (rule 3). A
module with no want is on no list and nothing applies it; a site runs while the proxy in front of it is down.

- Quick fix: skip rules 3 and 5 for the three modules' first wants. Leaves rule 5 holding every move and the
  canary holding new assignments.
- Thorough fix, chosen: rule 5 holds no want; it is said per node (Outcome.Unreached, journaled once per words by the
  pass). The canary (rule 3) no longer holds the first want of a node that does not run the module. A node that runs
  it keeps the canary order: at an older composed and granted fingerprint of the new form its first want stays at what
  it runs; at an old-form build it waits for the canary as before (issue 1945); at an older fingerprint with no
  composition or grant it gets F. This departs from ADR 0429 §6, which makes every provider healthy a rule of every want.

Tests: rows changed in the existing rule tests, and rows for today's modules (route-proxy down: de-spiegel and
link2pay wanted; minio not healthy: photos moves; novox offline: a first want written, a move kept back).

jschoubben 354b9ea396 mesh-delivery-assigner: read grants from the source the lease names (issue 774, ADR 0547 §4)
Why: from the lease write the grants part's state grants is the source and the controller's bucket otherwise; the assigner follows the lease key (a pass only when the source changes), and neither bucket stops its start. Needs the group's mesh-sdk pin (GrantSource, LeaseHandedAway, the assigner a named reader of the lease).

jschoubben ea3bfa5e6e Grant every node the keys a provider elsewhere serves from, and give the composition check frombus's new reads, pinning mesh-sdk cebc651 (issue 1126)
mesh-grants declares each module's served settings (catalogue.ServedSettings), so
the user list grants every other node's agent those keys of mesh-config_resolved
alone: shanks then settles what novox's mailu serves. The assigner's check of
every node reads no build, archive or served value: it composes as before.

jschoubben bb63d83f84 Derive a want's Self from the placement now, in every rule, so a want written while a node was placed does not outlive it (issue 1126)

After the placement seed's revert the rules that hold a want (a hold, rules 3 and 5) kept g14's and shanks's Self wants: the held branch copied them whole, and the rule branch wrote a want naming no composition, which EncodeWant refuses. Module.Self, set once from the placement, is now the one source, and every want the rules write or keep is derived from it: an unplaced node's kept want names the controller's composition of the same fingerprint, asked as any record move; with none, it stays and rule 7 says why.

jschoubben 92aedb9365 The first pass after a start clears failed-alone for every module and known node (ADR 0557, issue 1496)
Review round 2 of 16e4e61: gating the first-pass clear on a failed have left a
condition an earlier process raised standing for good once its node recovered
while no assigner watched. The first pass now clears it for every module and
every node the presence bucket knows, a quiet clear at the router for one that
is not open.

jschoubben 16e4e61a0f Only an online healthy witness, and only a first failure, keep a version from being held; failed-alone clears when a node leaves (ADR 0557, issue 1496)
Review of 2ee7589: a node that sleeps after running F healthy kept its stale
have as a witness, so F stayed unheld while it failed on the online nodes; and a
failed-alone condition was never cleared once its node left the module.

A witness must now be online by the watchman's presence. F failing on a second
node is no longer one node's failure: the hold and the set-back stand (ADR 0557
version 6, §2). A remembered failed-alone key whose node is no longer one of the
module's nodes is cleared once; the first pass after a start clears it for every
node the presence bucket knows, for a module with a failed have.

jschoubben 2ee7589474 A version healthy on another node is not held for one node's failed health check (ADR 0557, issue 1496)
On ace, 2026-10-26 21:19, a newly assigned mesh-build-node failed its first
health check at 8a98386f (later 31be2f24) while shanks, g14 and novox had run it
healthy for an hour. Being first by name, ace was the canary, and the assigner
held the version and moved the three healthy nodes back.

A failed health check of the newest fingerprint now holds it only when no other
node's have names it healthy (ADR 0557 §2 keeps ADR 0429 §6's hold and set-back
for that case). Otherwise the failure is that node's (ADR 0557 §1): nothing is
held or set back, the node keeps its want, and the assigner raises the node's
condition once (failed-alone.<node>.<module>), naming the node, the module, the
fingerprint and the have's words, and clears it once when it ends; the first
pass after a start clears what a previous process may have raised.

jschoubben f4aac599ca Assigner: name a running put when a node leaves neither list, and say the bus bar in plain words (issue 1945)
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.
2026-10-26 14:00:32 +01:00
jschoubben 2d63f0ba62 Assigner: say the bus bar instead of skipping it silently, and clear a neither condition only in true words (issue 1945)
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.

The held record is the memory that a fingerprint failed (ADR 0408 section 4); a revert returns the
trunk to exactly it, and without the key rule 3 would move the canary onto the failed build with
nothing asked. A stale hold ask now clears only the condition (raised again on a revisit), and the
hold is asked again under a new asking. Also read the single want key for a record ask.

jschoubben 98a05997ae Assigner: keep a held-back node's record ask, and clear the held record and condition of a stale hold (issue 1906)
Review round 1: a record ask is about the composition of any fingerprint a node may still want
(trunk, want, have), not only the trunk's, so deleting it looped with the wants rule that asks it
again and the operator was never asked. It is now stale only when the module left the trunk or no
read composition of those fingerprints has its digest. A hold or restore ask taken away as stale
also takes its held record and clears its held condition.

jschoubben 07dee528c5 Assigner: take away hold, restore and record asks whose fingerprint the trunk left behind (issue 1906)
An ask outlived its fingerprint: a lift left the restore asks of its fingerprint on every node,
and no pass removed an ask of a fingerprint that is no longer the module's trunk fingerprint,
so the operator kept being asked about a module that runs the trunk healthy. Each pass now
takes those asks away (the teller then withdraws the router ask), and a lift takes the restore
asks of its fingerprint. Nothing is taken away while the trunk or a composition is unread.

jschoubben 20027e53ff Delivery parts: a bucket the bus refuses at start stops a part only when it cannot work without it (issue 1945)
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.

jschoubben d4a054bfed Assigner: say why a node gets no want, in the journal and in its removed want (issue 1945)
A new assignment whose trunk build was not done fell through the rules
with nothing said: no want, no neither-list entry, no log line, and the
rule holding it back was computed and dropped. The pass now logs the rule
when a node's reason appears or changes and when it has a want again, one
line per change. A node whose want is removed and that does not run the
module gets the reason in that removed want's words, so assigner_want
answers why; a node with no key gets no removed want, since its node agent
would then remove the module and stop holding its resources back.

issued or sealed be wanted: on 2026-10-25 at 20:04 ace's mesh-build-go was
wanted with no ace.mesh-build-go on the bus, and crash-looped 20 times for
its missing credential. A grant that names accounts now grants a node only
when it names that node's own or a process's account; one that names none
grants every node, as before.
Research 072: the grants piece (memberships and credentials heard from placement).

jschoubben 91d041b62a mesh-delivery-assigner: a held module is never on neither list (issue 1945)
mesh/delivery held for a person: merged without a passing check: only a person decides what follows

systemd-resolved, held on shanks by the operator under rule 2, was raised
as an urgent "on no list" condition and reminded every hour, although its
hold is already said and answered on the held list. A node now goes on
neither list only when it gets no want and the module is not held, by a
hold read at its fingerprint or one this pass raises. The first pass after
a start clears the neither condition of every assigned node not on neither
list, not only those with a want, so a neither raised before the restart
for a held module (or a move waiting for its record ask) is cleared too.
