jschoubben 653ff61662 The node agent hands the vault what runs of an own secret its shadow answer says another value of, through move-in's replace_running, while it applies the controller's compositions (issue 1126, cause C4)
A new step, internal/ownresync, after each shadow answer: for each own secret masked as another value, while the node
applies the controller's compositions and runs the one its want names, it asks the vault's move-in with
replace_running: true and the running value sealed to the call's key, once per value, and says what it asked and what
the vault answered. The answer written to the node's have key carries values_differ. Pins the group's mesh-sdk head
1062b33 (go.sum is filled once that head is pushed).

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 4636261435 A failing placement read chooses neither composer, a deleting head is compared with the controller's compositions at the node's wants, and a placement watch that ends is said; pin mesh-sdk e32d777 (issue 1126, review of the shadow, round 1)

selfComposer took a KVHistory error for 'not placed': at any restart a timeout
or a bus not ready flipped a self-composing node to the controller's
compositions for a whole run. selfcompose.Placed chooses only on a read that
succeeds (a missing placement state is one), and tries again otherwise, said
once. The shadow's answer to a head deleting the placement reads the
controller's composition at each want in the node's bucket and compares it with
what runs; a want with none refuses, without returning.

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.

jschoubben d5adf9b72b Drop two debugging lines from the build read and H8, and say why the refused read's wait stays above the history bound (issue 1126, review round 1) 2026-10-27 21:21:19 +01:00
jschoubben 7365890298 Prove in H8 that a node reads a placed module's build and a provider's served key through its own session, refused without the grant, and take a failed have naming nothing as no module run inside the node's own; pin mesh-sdk 7a8e9f9 (issue 1126, review round 1)
H8 found it: a module the node could not compose yet got a failed have naming
no fingerprint, which counted as run inside the node's own composition, so the
next composition took it from its manifest past its build.

jschoubben 45439fd742 Compose each module from its build and read what providers elsewhere serve, pinning mesh-sdk cebc651, so a self-composing node hands its moved modules and settles mailu's domain (issue 1126)
The node read a behind module's source manifest digest and composed every module
from the indexer's raw manifest; frombus now takes the build itself (Scope.KeptAt,
a fingerprint). The reader gives frombus the builder's key, a templates archive
fetched as every archive is (apply.Fetch) once per digest and checked against it,
and another node's served keys one by one, as the node's grant allows them.

jschoubben 0184e2a5b8 Watch the have bucket only where the node's grant allows, so a node composing itself is not refused by the bus (issue 1126)
The fold's watch of every have key ('>') was refused (permissions violation on
CONSUMER.CREATE KV_node-engine_have), and every self-composing agent stopped
after the seed. The composer now watches '*.node' (records) and '<node>.>' (its
own haves), as buscompose grants a node; the shadow watches '<node>.>' too. The
selfcompose tests check every watch and get against PermissionsFor(KindNode),
and the agent's integration tests run the agent as the node under that grant.

jschoubben 06f70e11ee Bring in the adoption handing; the bus node writes nothing before it heard the switch, retries the key's watch and keeps the follow last heard, and an apply never writes the controller's list while the grants part's is followed (review of the switch, issue 1945)
Merges fix/1945-adopt-hashes 1a190090. A new follower (one per link) waits for the grants part's key to catch up before
its first write, so a restart after take-over never writes the controller's list first. A refused or ended watch is
tried again on link.Backoff, the have says why it is not watched, and the key last heard, kept beside the node's state,
holds meanwhile. While the grants part's list is followed, the bus module's composition is applied with the list on the
machine in place of the controller's. The grants list is never handed to the vault. Pins mesh-sdk c2a410bb.
2026-10-26 12:30:07 +01:00
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.

jschoubben 1a190090ab The engine states its key again until it hears the vault's key, and at a slow interval after, so a vault delivered after it or a changed vault key is heard (review of the adoption handing, ADR 0547 clause 9) 2026-10-26 12:03:12 +01:00
jschoubben fd381567f4 The bus node hands the loaded list's hashes to the vault, sealed to its key, in the bus module's have (ADR 0547 clause 9, issue 1945)
The vault holds no value for the controller's own account, the node accounts and the enrolled devices, so it cannot
hash them, and take-over waits on their hashes. The bus node's engine is the one part that has them, in the list the
bus loaded. Its follower of the user list now puts every loaded user's bcrypt hash in the bus module's have, sealed to
the vault's own key (mesh-sdk delivery.AccountsHanded), so of every reader of the have bucket the vault alone opens
it; the clear part says only the list's digest, the key's fingerprint and how many users. The vault's key is heard from
its answer to node-key, which the engine already asks at start; a first or changed key looks at the list again. It is
sealed again only when the list on the machine or the vault's key changes; a refused list hands the list kept on the
machine. The vault takes from it only the users it holds no value for.

Also: the user list follower's test sent its later puts before the watch had handed the keys there before it, so two
of its cases failed on main whenever the goroutine started late; the feed now says when the watch began.

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.

B1: the controller sends the user list by digest (over 64 KiB), so its users are counted from the list as resolved, not
from the composition's inline content, which is empty then.
R1: a composition signed for another node or module than its key names is no source.

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.

ace's filling refused mesh-build-go's files as not named as filled 32 s before
its want arrived; after the apply that named them nothing asked again, and the
runtime crash-looped on its missing broker credential. The filling now keeps
what it refused or failed and, when the node agent says a module's apply or
removal settled (agent.Env.Settled, called once what runs holds it), touches its
write socket if the declaration now names such a path, names the provisioner's
account, or a write had failed; the client watches that socket and fills every
module again. Said in the journal each time.

The facts look inside an apply runs while the module is still applying and judges nothing; the

jschoubben be5f31ce66 What runs is the agent's compositions plus the kept declaration's rest: health, filling, take act, directories and the others held out of an apply read it; a restart trusts the node-engine's own haves; the bed tests run off Arch (review round 1) 2026-10-24 18:13:40 +02:00
jschoubben e5a06cc73d The node agent waits for a backup's end on the holder's event, not by polling; the manifest consumes it (R6-A A5) 2026-10-24 17:03:30 +02:00
jschoubben 83f16cff8d apply FILE is no hand path: mesh-compose and a want are (ADR 0539 clause 10); genesis keeps the carried bundle 2026-10-24 16:55:23 +02:00
jschoubben b2003e7a38 A composition is applied only when the controller or the operator signed it; the node agent's integration tests on an embedded bus (R6-A A9, A1, A5) 2026-10-24 16:42:11 +02:00
jschoubben 3303797bfb The node agent runs in the node-engine: watches the wants and compositions on the link, applies one module's composition, asks the backup, writes the haves (R6-A A1, A5, A6) 2026-10-24 16:39:51 +02:00
jschoubben d5dd7761c6 The node agent: follows the wants and the node's compositions, applies one module at a time, backs a data module up first, holds it on a failed backup (R6-A A1, A2, A5, A6) 2026-10-24 16:36:21 +02:00
