jochen bb1607e424 Say when the mesh is wrong: conditions, watchdogs, the bus's advisories, doctor (hq to-be 45 Phase 1)
Every one of the 48 core failures of research 031 was found by a person
looking; the mesh's answers carried the fact for whoever asked and told
nobody.

- The condition store (to-be 45 §2): mesh-controller_conditions, one key
  per open condition, written by compare-and-set so a person's silence
  and the watchdogs never lose each other's word; every transition kept
  ninety days in mesh-controller_condition-history and said as the
  seat's events condition-raised / condition-changed / condition-cleared
  (the condition at the top level, with event, at, change, why, show),
  offered again while the bus is away. Raised and cleared by observation
  only; a clearing reopened within ten minutes is the same condition with
  its count up, its silence kept. Verbs: conditions, conditions show,
  conditions silence (a hand act, at most a week), conditions history.
- ADR 0224's provider standing is the first kind, provider-failing, held
  by the provider's events; the provider_standing table is no longer read
  or written (left in place: dropping it is the operator's word).
- status leads with the open conditions, urgent first, and says all well
  only with none open; conditions it cannot read are said and not well.
- The signals table compiled in, one watchdog loop over it every 30s: S1
  heartbeat (3 intervals, asleep machines excepted, control node urgent
  after 30 min), S2 report after a send, S3 plan tier, S4 event loop deaf,
  S5 merge not acted, S6 ask lost, S7 call hung, S8 provider silent, S9
  advisories, S10 self-check silent, S11 node tools silent, S13 stale
  refusals; S12, S14, S15 deferred with their reasons. A row that cannot
  see raises probe-failed and clears nothing. A test generated from the
  table suppresses each signal inside and past its bound.
- The bus's advisories (maximum deliveries, a mesh consumer deleted) and
  the controller's own slow consumer and refused subjects, said in the
  mesh's words.
- doctor: the probe registry D1-D10 (D5 deferred) and DW, every five
  minutes, each in thirty seconds; a probe that cannot run is never a
  pass. D1 validates with mesh-host's own validator. Every run ends with
  the doctor-heartbeat event mesh-watcher listens for.
- The controller is granted its new buckets, events, the two advisories
  and $SRV.INFO; the node tools their tools-alive heartbeat. The streams
  and consumers the controller asserts and the ones D6/D7 expect are one
  derivation.

jochen 9d8cbe7b81 Grant the controller its work queues' cancelled sets (hq issue 269)
A cancel writes the ask's id into the seat's cancelled set before deleting
the ask, and a write is a publish to the bucket's subject, which the
controller was not granted: against a server holding exactly the
controller's composed list, every cancel timed out.

jochen e74c32ed50 Keep calls and hand acts on the bus, answer status at once, record durations (hq to-be 45 Phase 0)
A controller restart lost every call's outcome, `status` composed the mesh
while its caller waited (18.6s live on 2026-10-06, past the 10s window), a
repair by hand left no trace, and the core's bounds had nothing measured to
be set from.

- calls: kept in the controller's bucket mesh-controller_calls (last 1000 or
  14 days, answers bounded to 64 KiB), read by id across a restart; a
  controller starting marks a stopped one's running calls abandoned; each
  call names its caller from the inbox its answer goes to.
- status: the serving controller composes it at start, after news from a
  machine, a build or an acting verb, and every minute; the verb answers the
  last composition at once with when and how long it took. Composing resolves
  each machine once instead of twice.
- hand-act log in mesh-controller_hand-acts: push (required through the seat),
  plans stop/close, broker consumer-reset and the new hand-act record take
  --why/--cause/--condition; `hand-acts` lists them and repeated causes;
  status counts the week's.
- durations (migration 0066): apply (send to first report), heartbeat gap,
  plan tier and build, recorded as heard; `durations` summarises them.
- the controller's seat row takes this binary's definition of its own verbs,
  so the console no longer judges calls against an older build's schema.
- the controller is granted its two buckets' subjects.

jochen 6d620f77c3 Bound a consumer's identity by the provision it requires (hq issue 263)
The one global 20-character bound made every consumer pay an object
store's key length, even for provisions that keep no name, and a single
overflow refused the provider's whole declaration. An offer now states
its own bound (identity: {max, in} or false); unsaid, a provider told its
consumers keeps 20 and one told nothing keeps none. module check judges
every identity on the longest machine name before merge, and a provider
leaves an overflowing consumer out of its grants and composes, with the
consumer named by push, plan and status (ADR 0225).

jochen f8286c063d rotate: narrow a pair credential to one consuming module (hq issue 268)
A machine runs many consumers of one provision, each with its own
credential. When one module leaks its credential, `rotate <provision>
--consumer <machine>` was the narrowest act and replaced every module's
on that machine, restarting all of them. --module (and the verb's
module argument beside provision) rotates only that module's.

jochen 09c0c6b367 Keep the account of the sent declaration over an older one (hq issue 267)
The last report stored per node decides whether a release plan moves on,
and it was whichever arrived last. A report about a declaration the mesh
has moved past now records what it says about the machine but leaves the
account of the apply alone, so arrival order cannot undo the newer.

jochen 59f4d486b1 Catch up on merges the bus announced and never handed over (hq issue 266)
The controller acted only on what its events consumer handed it, so a merge
the bus skipped left modules behind with nothing said. The stream is now read
back every five minutes on a single-filter consumer, and any merge that would
still move a module after ten minutes is said and acted on.

jochen 801552c0eb Answer every seat call within ten seconds and keep what came of it (hq issue 265)
A push outlasted the console's 30s wait and, when it sent the bus its
changed user list, the broker's reload forgot the reply it may send:
the push happened and its caller was told it did not answer. Calls now
answer in full or as running with an id, a push answers before it
sends, refused answers are recorded on their call, and 'calls' reads
them back.

jochen 0f0028785c Refuse a verb argument the seat would pass over, and say a push is of the whole mesh
A push naming one machine reached the verb without it and pushed every
machine behind (hq issue 244). The controller now refuses any argument a
verb does not declare, any it composed its command line without, and a
switch that is not true or false; a push that names no machine says first
that it is the whole mesh. Tests walk every served verb: no argument is
ever ignored, and every flag of a verb's command, read from the source, is
in its schema or accounted for. plan gains files, push behind, builds and
plans limit.

jochen 8d9d33ae85 Report a provider that keeps failing a consumer in status (hq ADR 0224)
The identity provider failed every consumer for a day and status called the
mesh well (hq issue 179). The controller now follows every provider's
provisioner.failing/recovered, keeps the newest failing word per provider,
machine and consumer (migration 0065), and status, its JSON and node show
name it until it recovers. Every module that receives contributions is
granted the two events, so no manifest can forget them.

jochen ee99a24f77 Rename node-hosts-file to node-hostname, and refuse one seat claimed under two names (hq ADR 0223)
The seat now covers /etc/hostname too. The migration keeps the old name as
an alias so hosts, still assigned while machines move, holds the same seat.
Claims were compared by spelling, so the old and new module would both have
held it on one machine; they are now compared by the seat they resolve to.
2026-10-05 23:43:15 +02:00
jochen f68521da28 Retire node-resolver-config and the seat need it alone used (hq ADR 0223)
The uplink's holder writes /etc/resolv.conf, so the seat that wrote it and
ADR 0220's dependency of it on the uplink have nothing left to say. The
migration deletes the store's row; nothing holds it once resolv-conf is
unassigned everywhere.

jochen 296064c799 Test the resolver file as the uplink's, and refuse a second writer of a fact's path (hq ADR 0223)
The catalogue moves /etc/resolv.conf from resolv-conf to the three uplink
modules. A rendered fact was not compared with other modules' paths, so two
modules could each write the resolver file on one machine, the last winning
every apply; a fact's path now counts as its module's.

jochen f506fb34ec Let the mesh's resolver seat have several holders on record
musl takes the first reply from any listed nameserver, so a public fallback
beside the mesh's resolver answered NXDOMAIN for mesh names in every Alpine
container (hq ADR 0223). The fix is two mesh resolvers and no public one, which
needs mesh-dns-resolver held on two machines: a seat can now be replicated,
each holder recorded by 'seat <name> --add', checkClaims accepts every holder
on record and still refuses a second holder of any other mesh seat, a holder
answers its own requirement, and a roster fact gives each replicated seat's
holders, this machine first, so resolv-conf can list them. Migration 0062 keys
a holding by seat and assignment.

jochen 2421b82ad2 Keep a named push from sending builds a policy or a plan holds back
A named push flushed every other machine whose declaration differed from
what it was last sent (hq ADR 0083). Under an upgrade policy of `record`,
or a plan still waiting on its first machine (ADR 0218), every machine
running the module differs, so `push <one>` sent the held build to all of
them (hq issue 259).

Each send now records which build of each module it carried
(node.sent_builds, migration 0061). The cascade, and the bus holder added
to a named push, skip a machine any of whose modules would move to a
build its policy records or an open plan has not sent it, and say which
module, which build, why, and that `push <node>` sends it. A machine
whose last send was not recorded is held until it is named. The named
machine itself, a whole-mesh push and `push --behind` are unchanged.

jochen 0ebd48a6a8 The private network writes nothing into the runtime's file (hq issue 190)
daemon.json and docker.service belong to the docker module, which holds node-container-runtime
and now states the registry itself through ${seat:mesh-artifact-store:reach} (hq ADR 0222). The
overlay stops generating registry-trust and registry-trust-reload. A generated resource is now
held to the collision check every module is, so a second writer cannot come back through
computed code; resolution never saw what a generator declares.

jochen 67e291c02a Tell a module where a mesh seat's holder is reached (hq ADR 0222)
The container runtime's module must state the mesh's registry to the runtime it owns, so the
controller can stop writing that into the runtime's file (hq issue 190). ${seat:<seat>:reach}
answers host:port without a binding: nothing required, granted or minted, and the address is
one the mesh already composes into every reference it built. Only mesh-artifact-store is
answered; another seat is refused by name. Unanswered in a file written into as JSON, the empty
member is dropped, so the runtime is never told to trust "".
2026-10-05 22:16:23 +02:00
jochen 53d3cd7ce9 Delete node-dns-resolver and make resolver config need the uplink
Nothing has claimed node-dns-resolver since the mesh moved to one resolver
(hq ADR 0194); seeding never removes a row, so a migration deletes it.

resolv.conf stays the mesh's only while the network manager is told to keep
off it, which the node-uplink holder does (ADR 0117). A seat's Needs makes
that a dependency checked at assignment by the ADR 0207 mechanism (hq ADR
0220). The two-claimants test keeps its intent with a synthetic module now
that resolved-split-dns leaves the catalogue.
2026-10-05 21:57:04 +02:00
jochen 7fa2568ce7 The controller writes no /etc/hosts (hq ADR 0199)
/etc/hosts is the file of the node-hosts-file seat's holder; the controller writes into no file
another seat's holder owns, and asks that holder if it ever needs a line there. The private
network's module stops asking for the node-names fact; every machine already asks the mesh's
one resolver for these names, and the host gives the region back at the next push.

jochen ce86d09d22 A mesh seat's holder elsewhere answers before this machine's own provider (issue 258)
A mesh-wide provision a machine could answer itself was bound to the local provider, with the
seat's holder and any pin consulted only for a provider on another machine. With every machine
still running its own resolver, each bound its resolver configuration to itself while the mesh's
one resolver was held and pinned elsewhere.

jochen 853be00ebe The runtime's file is the runtime module's: the resolver test expects docker to write live-restore (issue 190, ADR 0196)
The catalogue moves daemon.json's live-restore and the reload from resolv-conf to the docker
module, so no module writes another software's configuration. The test composes docker beside
the resolver modules and refuses resolv-conf writing the runtime's file.

jochen 9873b3bf13 Keep a replay from moving the mesh backwards, and tighten the queue's edges (review of hq ADR 0219)
A registered replay asked now outranked newer asks of its module, and a plan
took any later outcome as its answer. A replay is now refused while the module
is asked anywhere, a plan module asked under an id is answered by that id
alone, and a rebuild of a commit asks what the module follows. An ask handed
back after a restart no longer reads as dead; a cancel that meets a start is
withdrawn; pause holds for an ask fetched as it lands; kill removes containers
before and after the build ends and says whether its outcome went out; a
holder may say only its own machine is paused.

jochen 541603c15c Announce the build agent's verbs, let a waiting build hear its cancel, and retry a stopped rollout (hq ADR 0219)
The holder's verbs were served and found by nothing; it now answers discovery
with its machine's four, as a runtime announces a seat's verb, so the console
finds <node>/node-build-agent.kill. A cancel publishes no outcome, so a build
waited for also looks at the cancelled set. A plan that stopped at its first
machine is retried by sending that machine the module again, unless a newer
plan holds it.

jochen 106507b1d3 Show and change the build queue through the controller, and have plans follow it (hq ADR 0219)
Nothing showed what waited for a build machine, and an ask could not be
dropped without leaving the plan that made it waiting for ever. New verbs:
queue, cancel, clear, rebuild, replay, kill, pause, resume, and plans retry.
Every ask a person drops is recorded failed through the same take-in as a
failed build; a plan keeps the id it asked each module under and matches
its outcome by it. replay is a dry run unless registered, and registering
an older commit than one registered since needs --older (hq issue 207).
A plan waiting on a seat paused on every holder says so and is not late;
a failed plan can be retried, and a rebuild joins the plan holding the
module instead of running beside it.

jochen e610f2d92c Let a build agent be paused, have a build killed, and end an ask cancelled as it took it (hq ADR 0219)
A queued ask could only be waited out and a running build only ended by
stopping the machine, which redelivered it elsewhere. The holder now serves
current, kill, pause and resume on its own machine's subjects; a kill ends
the build's process group and labelled containers and settles the ask as
failed, killed by hand; pause is kept in the workspace across a restart and
said on the bus. The controller writes cancelled ids to a cancelled set the
holder reads on taking an ask, closing the race a delete alone leaves.

jochen ed90771382 Send the bus's machine before the grants, and only when its user list moved (hq issue 249)
Grants first could hold back the very declaration that lets the controller
issue them. The holder now goes first, then buckets and memberships, then
the rest; a membership that fails holds back only its own machine, and an
announcement whose send stopped at its grants is asked again. Whether the
holder must go first is read from a digest of the user list it was last
sent, not its whole declaration. Migration renumbered to 0058.

jochen 208901c6cc Let a newer plan supersede the older open plans of its repository (hq issue 254, ADR 0218)
A merge planned without looking at open plans, so two plans worked the
same modules and a stuck plan stayed open for ever. The newer plan folds
in what older plans of the same repository and branch had not built or
sent, and closes them as superseded. A person can close a stuck plan by
id with `plans close <id>`.

jochen 4ac5cfe3a7 Roll a plan's module out to one machine first (hq issue 249, ADR 0218)
A plan sent every machine running a module at once, ignoring the module's
upgrade policy. Unless the policy says together, the first machine by name
is sent, recorded in the plan, and the rest follow only once its report
after the send says it applied; a failed first machine stops the plan.

jochen 01c5ab2aab Hold every kept archive by a manifest so the store's collector keeps it (hq issue 253)
The store's garbage-collect marks only from manifests, and archives were
published as bare blobs, so the first real collection would delete every
archive the mesh keeps. PublishArchive now puts a deterministic OCI holder
manifest (empty config, one layer) beside each archive; the sweep holds every
kept archive before it lets anything go, which backfills existing bare blobs,
and lets go of an archive holder-first. A forgotten module no longer keeps its
five recent builds (ADR 0189). `collection [--json]` reports kept archives
held/unheld and what may be let go, so the dry run can be lifted on evidence.

jschoubben d25b69178b The node-backup seat: a module contributes its backup, the mesh fills its directories
ADR 0214 / to-be 43: a node seat whose holder keeps nightly restore points of what every module on

per module when placed. The catalogue check refuses a store provider that contributes no backup;
parsing does not, so the providers already running stay readable.

jochen 4ed1057df3 Compose a bus user only for a module that can read an account
Every assigned module was composed as a bus user, though only one declaring

real gaps. Their durable consumers are now derived from what the runtime
carries, so nothing they hear changes. The composed file is unchanged:
those users had no password and were already left out. Fixes hq issue 195.

jschoubben 1f4c67a01b The mesh's one resolver: its seat, a provider's address, zones, and a node's hosts file (hq ADR 0194, 0196, 0199)
- mesh-dns-resolver: a mesh seat delivering wildcard-resolution, so every node's resolver
  configuration resolves to its one holder; node-dns-resolver kept until nothing claims it.
- ${bound:<provision>:address}: the providing machine's private address, for the one consumer
  that cannot use a name — a machine's resolver configuration.
- zone: a module declares the zone it answers and the listen that answers it; the controller
  settles it per node, refuses duplicates and shadowing, and hands the resolver .Zones to forward.
- node-hosts-file: a node seat whose holder owns /etc/hosts, with entries/add/remove.
The resolver tests follow the catalogue: no runtime dns (containers copy the machine's resolvers),
live-restore held by resolv-conf, resolv.conf naming the resolver by address then a public one.

jochen b7912172af A seat says what it receives, and its holder places every module's contribution (hq ADR 0212)
Each contribution grain was a manifest field and a renderer of its own; a module now contributes

${contribution:<seat>:<kind>}, and the contribution depends on the seat. node-hotkeys is the

jochen 6af891e358 A contribution depends on the seat that receives it, and a collision is refused at assign (hq ADR 0210, issue 235)
The environment and shell contributions were written nowhere on a node without their holder;
they now derive a dependency on node-environment, node-login-shell or node-display-server, met
and refused as ADR 0207's are. Two modules declaring one package, path or unit made the node
unresolvable after the assignment was recorded; that is refused first now, because no later

jochen 35314175f2 Refuse an unmet seat dependency the catalogue could meet (hq ADR 0207 §4)
