A module is one piece of software and may still carry a daemon in one language,
tools in another and a package in a third. The first cut compiled every bundle
into the toolchain's single output directory, so two of them would have
overwritten each other and then been packed together — one artifact containing
both, published twice.
So output is a property of the artifact, not of the toolchain, and the toolchain
says how it is told where to write rather than where it writes. Under a directory
named for the build rather than beside the source, so a pack never sweeps up the
module's own working files.
A second toolchain is declared so the multi-language path is exercised rather
than asserted — a list with one entry cannot fail the way a list with four will.
And the fake compiler in the tests now writes where it was TOLD to. One that
always wrote to a fixed place would have passed whether or not each artifact got
its own directory, which is the whole of what these tests are for.

The bundle recipe: the one that both builds and packs. An archive packs a
directory as it stands, so shipping compiled output meant compiling somewhere
first — which meant a Dockerfile repeating the same incantation in every module.
Two base arguments with no defaults, a working directory chosen so the SDK
resolves upward, the compiler invoked by absolute path because the usual symlink
is resolved away when the base image is assembled, a second stage, an environment
variable naming the entrypoints. Most of the catalogue is unconverted and that is
why; two conversions done in one session were each wrong twice with a working
example open in the next window.
A bundle says a language and a list of entrypoints. The mesh knows what the
language implies. Anything a module could override there it would be writing a
Dockerfile to override, so a toolchain is deliberately not configurable.
Declared rather than inferred, both of them: guessing the language from which
files are present makes a build depend on a directory listing, and guessing the
entrypoints makes it change meaning when somebody adds a helper.
A toolchain the mesh does not hold is refused before anything is compiled, naming
what to build first — the same treatment a missing base already gets, because it
is the same question and somebody can answer it. A language the mesh does not
build is refused saying what would have worked, since the author is usually one
word away.
The list of languages is closed and adding to it is a decision. Every language is
another implementation of the contracts every module shares, and those change
rarely and cascade when they do (ADR 0039) — a mesh whose SDKs disagree about the
envelope fails by ignoring messages rather than by failing to compile.

Its event queue is durable, so a running catalogue misses nothing. What it cannot
have is what was announced before it first ran — and on a fresh mesh that is never
arbitrary: the shared base, the store the catalogue runs on, and the catalogue
itself are each necessarily built BEFORE a catalogue exists to hear about them.
The graph's foundation is the part it never sees.
So it says it is catching up, and the control plane re-announces what it
recorded, oldest first, marked as a replay. Oldest first because a graph is built
in the order things happened: registering a module that stands on a base before
the base would point an edge at a version nothing has seen, and the shape of a
fresh mesh guarantees the base is both first and the one that was missed.
The replayer hands announcements back rather than publishing them, because the
wire belongs to the link package and a replay building its own events could drift
from what the builder emits — the one thing it must match exactly, since the
catalogue has a single handler for both.
Its own queue and its own consumer: two consumers on one queue split its
messages, and a catch-up request going to whichever half was not listening is a
gap that looks like a working mesh.

The builder announces a build with the resolved manifest, the path inside the
repository, and every artifact it stood on. The control plane received all of it
and kept none of it.
That was survivable while the catalogue heard the same announcement directly. It
stops being survivable the moment the catalogue was not there to hear it — which
on a fresh mesh is always, and always for the same modules: the shared base, the
store the catalogue runs on, and the catalogue itself are each necessarily built
BEFORE the catalogue exists to hear about them. The graph's foundation is the
part the graph never sees.
Replaying those builds needs what they said, not a summary. Without the manifest
there are no requires/provides edges; without `against` there are no build edges,
which are the ones that answer "a base moved, what must be rebuilt". A replay
carrying neither would restore the module list and leave the question the
catalogue exists for still wrong, while looking fixed.
Kept null rather than empty where a build predates this, so a replay can say it
is holding nothing instead of inventing an empty declaration for a module that
certainly had one. And `built_against`, not `built_on`: that column exists and
means the machine, which is a different fact about a different subject.

Rules are derived from what modules declare they listen on, and the substrate is
not a module. So the broker's port — the one every machine dials to enrol and to
receive every declaration it is ever sent — appeared in no ruleset the mesh has
ever generated.
Nothing caught it because a mesh of one never dials its own broker across the
network: the ruleset looks complete right up until a second machine tries to
join a firewalled anchor and is refused by the packet filter, during enrolment,
before the mesh can report anything about it. Assigning the firewall before
joining machines is both the natural order and the one that breaks.
It is a floor for the same reason ssh is. A machine nobody can reach cannot be
repaired; a machine the mesh cannot reach cannot be managed. Neither is a thing
any module asks for and neither may be derived away.
From anywhere rather than from the private network, deliberately: a node enrols
BEFORE it has an address on that network, so narrowing the rule to it would close
the door being knocked on.
The port is read from the broker this control plane was told about, so the
address handed out in a token and the port a machine must accept on stay one
fact. A mesh never told about a broker gets no such rule, rather than a broken
one — and cannot issue tokens either, which is where that surfaces.

Two sibling branches resolve a provision answered by the consumer's own machine.
The one for a node-scoped provider falls back to loopback when the machine is on
no private network, with a comment saying why and a test holding it. The one for
a mesh-scoped provider passed node.At straight through, and nothing noticed
because nothing had yet composed a host out of it.
The mesh's own artifact store is mesh-scoped and sits on the same machine as the
builder that pushes to it. Give the builder the address from its binding and it
gets MESH_REGISTRY=:5000 — a name with no host, written into its environment
without complaint. It surfaces much later as
":5000/mesh-tools/build" is not a valid repository/tag
which is a message about a tag for a fault in how a binding was resolved, on a
machine several steps from the decision.
A machine off the private network still reaches itself, which is what the
neighbouring branch already said. The test fails without the fix, showing the
empty address rather than only the symptom.
Claude-Session: https://claude.ai/code/session_01D6qtiYU3P9jk3pnAXyAFyx
The check read "declares no resources" as "runs nowhere", and those are not
the same. The private network declares no resources either — the control plane
computes them when it composes a machine's declaration — and it is assigned to
every machine that has to reach another one. Refusing it stopped a four-machine
bed at its first assignment.
The signal is narrower: it builds an artifact and places nothing. Made a
function of its own, because a judgement with a wrong answer this expensive
should be testable without a database — nothing guarded it, which is how it
shipped.
The floor allowed ssh from the mesh's addresses, and from everywhere on a
machine that faces outward. On a machine the mesh knows no addresses for it
emitted neither — so the chain dropped by default and ssh was simply shut.
That is the first machine anybody adopts: reached over the network, with the
port needed to fix it closed by the act of adopting it. Found by reading the
rules off a live machine rather than trusting the generator.
Two faults, opposite directions, both in issue 047.
There was no forward chain, on the reasoning that dropping there stops every
container the runtime allowed. The first half is true; the conclusion was not. A
published port is redirected and then forwarded, so it never reaches the input
chain — the firewall was silent about the ports most worth protecting. The way
through is the one the system being replaced already used: deny by default, then
allow the runtime's own networks explicitly. A forwarded rule matches what the
client originally asked for, because the destination has been rewritten by the
time the chain sees it.
And ssh is now a floor nothing derives. Every other line comes from what is
assigned, which is the point — but a mesh part-way through adopting a machine
has been assigned almost nothing, so what it computed was a chain that shut the
port used to fix it. From the mesh always; from outside on a machine that faces
outward, because that is the way in when the private network is what broke.
Rehearsed on three machines: a docker-published port declared mesh-only is now
reachable from inside the mesh and refused from outside. Before, it was
reachable from both.
The image every module in the scripted toolchain is compiled on top of is
registered as a module so the mesh can build, version and depend on it. It is
not one: nothing about it belongs on a machine. Assigning it succeeded, the
machine was sent a declaration containing nothing of it, and everything
reported success — the operator had said run this here and the mesh had agreed
to something it cannot do.
A module whose resources are worked out per node is asked about separately, so
it stays assignable, which is the point of it.
A fingerprint written into a recipe names one particular copy of the base — the
copy on whichever machine the person typing it was using. On any other mesh that
copy has never existed, so the build stops on its first line with a message
about an image nobody can look up. Three modules in the catalogue were in
exactly that state, and the line each of them replaced was equally dead.
A module now names the module and artifact instead, and the mesh answers with
what it holds. The builder is still a thing that clones, builds and answers: the
answer travels with the question, because only the mesh knows what it has.
A base the mesh has not built is refused before anything is built, naming which
module has to exist first.
A container naming an artifact is a module saying the mesh builds this. Until a
build publishes one there is nothing to run — and what reached the machine was
an unresolved field, which its language has no room for, so it refused the whole
declaration and reported that a container does not use "artifact". That reads
as a broken manifest. It is not broken, it is unbuilt, and only the mesh can
tell those apart.
Found by the four-machine bed, which assigns modules the mesh has not built.
This is how a mesh is raised: the installer carries this program and runs it
once, before anything exists, to produce the control plane from the same
repository and path every later rebuild will use. What raises the mesh is then
the same thing that maintains it, rather than a second mechanism exercised once
per new mesh — which is how often enough to rot.
With nowhere to publish, an image stays in the machine's own runtime and is
named by the digest of its own configuration: the same identity the installer
has always used for the image it carried.
The builder says what it built and the catalogue decides whether that was an
upgrade. Only the control plane knows which machines run the thing, so it is
the one that acts — and what it does is a choice somebody recorded, not a
behaviour compiled in: record that they are behind, or send it, one machine at
a time or together.
Recording is the absence of an action rather than a second path: a machine not
running what the mesh would send it is already something the mesh reports.
Defaulted to recording. A mesh that rolls out everything it builds the moment
it builds it is reasonable to want and a bad thing to arrive by default — the
first module to inherit it would be the control plane, upgrading itself out
from under the push applying it.
Answering and announcing are different acts. The reply goes to whoever asked and
is correlated to their request; the announcement says to the whole mesh that a
module now exists at a commit, which is what the catalogue places in the module
graph (novox/hq ADR 0072). A build nobody asked for still has to be announced, or
the graph knows less than the registry does.
What it was built on top of is read out of the build's own inputs rather than
declared, because a declared list drifts from what the code actually uses
(ADR 0009). These are artifact references, which is what a build input names;
resolving them to module-versions is the catalogue's work, since it is what knows
which module-version published which artifact.
Events ride the topic exchange, not the direct one nodes speak over, so the
builder's account is granted both: it must be able to answer and to announce.
The envelope is the sdk's, reproduced exactly — a second shape would be a second
thing for consumers to handle, and they are written against the first.
Announcing is not allowed to fail a build. The work was done and was answered; a
build reported as failed because saying so failed is a lie about it.
Claude-Session: https://claude.ai/code/session_01D6qtiYU3P9jk3pnAXyAFyx
The builder cloned a repository and read the manifest at its root, which means one
repository per module. Nothing we have is shaped that way, so the builder could be
asked to build nothing that exists (novox/hq ADR 0069).
The path travels the whole way — named when asking, carried in the request, used
to read the manifest and as the context everything is produced from, echoed back
in the result, and recorded as part of where a module came from. Without that last
part the mesh could notice a module was behind its source and then be unable to
rebuild it, which is the worst of both.
A path climbing out of the clone is refused: a machine whose job is building other
people's repositories must not read whatever else is on its disk.

0056 is 'the authority is the control plane, not a database'. A citation
pointing at the wrong decision is worse than none: it reads as corroboration.
Claude-Session: https://claude.ai/code/session_01LrgweAeERJYBg88c5cKDzF
A store connection string carries a password, and the control plane took it
from MESH_STORE_<CONTEXT> — an environment variable, which is readable in
`docker inspect`, in the process's own /proc entry, and in whatever composed
it. Every other module in the catalogue is given secret material as a file the
mesh sealed to the machine and the host wrote.
That difference is what stopped the control plane from being an ordinary module
(novox/hq ADR 0067). A manifest can put a sealed value into a file's `content`
with ${secret:…}; it has no substitution into a container's `env` at all. So a
control-plane manifest could be written with the password in it, or without the
setting — neither honest. The fix is not to change the manifest format but to
let the control plane read what everything else reads: a file.
MESH_STORE_<CONTEXT>_FILE names one. Exactly one of the two may be set; both is
refused rather than settled by precedence, because whichever won, the other
would still read as the setting in force and the process would be writing to a
store nobody expects. Trailing whitespace is trimmed — a file written by a
person or by a filled-in placeholder ends in a newline, and a newline inside a
URL is rejected several layers from anything that could explain it. Leading
whitespace is left, being a mangled value rather than a habit.
The no-leak property is kept and extended: a file that cannot be read names its
path, never its contents, and the parse failure now names whichever source was
used because a variable name and a path are not the secret.

An authority inside the mesh is reached at <machine>.internal, so its own
certificate must be issued for that name — and it is the one module that cannot
be told its name by a binding, because it provides rather than requires. Written
as a literal it would be one deployment's machine name in a manifest, which is
what ADR 0056 exists to remove.
${machine:name} and ${machine:at}, beside the bound values and refused the same

`module forget` cascaded. The settings, the module's own secrets and the ports the mesh
chose all name the module by a foreign key that cascades, so removing the row took all
three and reported "forgotten" — an action succeeding into a state its own verify would
reject (novox/hq 04-ISSUES/017). A sealed secret is not recoverable afterwards, because
the mesh discarded the plaintext when it made it.
It now reads what it would destroy, names each thing one at a time, and refuses.
`--and-what-it-holds` is how somebody says they mean it, and the removal then reports
what went — this being the only record that any of it ever existed.
Reported as "operator settings do not persist, because re-registering a module
cascade-deletes them". Half of that is wrong, and the test now says so out loud: the
upsert is on the name, so `module add` at a new version leaves the settings, the secrets
and the ports exactly where they were. The command that destroyed them was `forget`, and
a wrong belief about which command destroys data is expensive in both directions — it
sends people looking for a fault that is not there, and leaves the real one unexamined.
Checked by internal/inventory/forget_test.go, which writes all three, re-registers the
module at a new version, reads them back, and only then tries to forget it.

The co-located fix could not reach a grant assembled for a consumer on another
machine: ContributionsFrom never sees a port map, so the proxy was told the
workload's software port and dialled a number that machine never published. The
consumer's own assignments are fetched where the grant is built and applied
there. The same fault as 038, one node over.
Claude-Session: https://claude.ai/code/session_01LrgweAeERJYBg88c5cKDzF
servedOnThisMachine stopped at the first module whose `serves` mentioned the
provision, even when that entry was empty and there was therefore no fact to give
a consumer. here() had always kept looking in that case, and a set where one
module names a provision without describing it and another describes it is exactly
where the difference shows. Restore the search.
Claude-Session: https://claude.ai/code/session_01LrgweAeERJYBg88c5cKDzF
Two more of one fault, and the fault is the same as 04-ISSUES/038: the same-node
path diverging from the cross-node one.
The mesh works out what a provider on ANOTHER machine serves by walking that node
— reading its manifest with that machine's port assignments, then settling the
result with that node's settings layers — before offering it to a consumer. A
provider on the consumer's OWN machine never passes through that walk, so every
step of it had to be repeated in resolve.go's servedHere and declaration.go's
here(). 038 repeated the port. Nothing repeated the settling.
So a served value the operator supplied reached a co-located consumer as the
manifest's empty default. On the ADR 0056 anchor that value is an internal CA's
root: step-ca and route-proxy on one node, route-proxy's binding carrying
root: "", an empty CA bundle written, a silent fall back to the system trust
store, and issuance stopping with nothing saying why. The same step-ca on another
node would have worked.
The second is the mirror direction. gitea declares a bare container port 3000 and
the machine publishes it as 20000:3000, but gitea's route CONTRIBUTION still said
3000 — so the proxy beside it dialled a port nothing listens on and answered 502.
038 fixed what a consumer is TOLD about a provider; this is what a workload TELLS
a provider about itself. The redirect uses the CONTRIBUTING module's assignment,
because the port is the workload's, not the proxy's; a contribution carried here
from another machine is left exactly as it is, its port being that machine's to
assign.
Both are settled in Declaration, which is the first moment the machine's ports and
the provider's settings both exist. That also removes an order dependence: the
resolver built its same-node needs mid-walk, from whichever modules had been
chosen by the time the requirement came up and in whatever order a map iterated,
so what a co-located binding carried depended on the order somebody happened to
assign things in. Re-deriving from the finished closure does not.
servedHere keeps its job — deciding whether a same-node provider serves anything
at all, which is what makes the need exist — and now says that its values are
provisional.

An empty label composed nothing, so a module served at the bare domain (a node's
own site) had to keep a full name — the one route the label model could not
express. The zone-file convention '@' now composes to the public domain itself,
no leading dot, so the apex is a label like any other. Test added.
Claude-Session: https://claude.ai/code/session_01LrgweAeERJYBg88c5cKDzF
A public route used to carry its whole hostname as a literal in the module
manifest, so running the same catalogue against a different domain meant
overriding that literal on every routed module, per node. The mesh was, in
effect, holding a map of names to services: the one thing it should never hold,
because the subdomain is the operator's choice and the domain is the node's.
Compose instead. A route contribution carries a `label` (the subdomain); a node
carries its `public_domain` as node-level configuration; the mesh joins
`<label>.<public-domain>` and grants exactly that, interpreting neither half.
Held as a node property beside the node's other node-level facts (endpoint,
site, overlay address), not in a module's settings — the ADR calls it
node-level, and the settings table is keyed per module.
Additive, so an unmigrated catalogue keeps working: a contribution that still
carries a full `name` and no `label` passes through unchanged, and the catalogue
can migrate module by module. A labelled contribution on a node with no public
domain composes nothing, reading downstream as a route that named no host.
And propagate: each granted route name is published into internal resolution
mesh-wide, mapped to the node that serves it, alongside the `<node>.internal`
names every container already gets. So a container — and an internal ACME
validator, which cannot complete a challenge for a name it cannot reach —
resolves a routed name to the proxy that serves it. Name-agnostic throughout:
the mesh propagates whatever names it was told to serve and knows nothing about
what they mean.

A co-located consumer of a `from: mesh` provision was told the port the
provider module DECLARED, not the host port the mesh assigned and published
it on. The same-node served facts are settled while resolving (servedHere,
here()), before a bare `ports` mapping is assigned its host port, so they
carried the declared number; only the cross-node path re-derived them after
assignment. So the provider was published on <node>.internal:<assigned> while
its own-machine consumer dialled <node>.internal:<declared>, where nothing
listens — the ordinary small-mesh case, and the one the fix for issue 018
(announce the same-node provider at all) left one promise short of kept.
Redirect same-node needs to the machine's assignment in Declaration, where the
port map is known, exactly as plan.go already does cross-node. The publish bind
is unchanged (all interfaces, scoped to the mesh by the listen's firewall rule);
only the announced port is corrected.

A module a person assigns to a machine that cannot host it — its declared
capability has no detector there, as fail2ban does on a host with no firewall —
made Resolve refuse the entire node, so a whole-node push refused to send the
healthy modules beside it too. One module on the wrong machine took down every
other module on that node.
Assign already keeps such an assignment on purpose (it is what a person meant,
and acts.go says so), so the fix is on the resolve/push side: a directly-assigned
module the machine cannot host is left out of the closure and reported as
un-applied on the Resolution, rather than refusing the set. The healthy modules
still resolve, declare, and converge. A module that is *required* by something
running here and cannot be hosted still refuses — that set is genuinely
incoherent — so the distinction is who wanted it.
assign, plan and push now name the un-applied module and the missing capability,
via a shared WrongMachine message, so it is neither silently dropped nor fatal.
Reconciled two tests that encoded the old whole-node refusal for directly-assigned
un-hostable modules; added coverage for the healthy-modules-still-converge case
and the required-un-hostable-still-refuses distinction.

A container with `network: host` was skipped when the mesh injects its
`<node>.internal` names, on the belief it "shares the machine's hosts file
already". It does not: `docker run --network host` still gives the container
its own /etc/hosts (localhost and its own id only), so every internal name the
mesh wrote is invisible inside it, and a client that dials one gets EAI_AGAIN.
This surfaced with the first host-network consumer to dial a provider by the
`.internal` address the mesh hands it as `${bound:...:at}` (the model-usage
store reaching its postgres). The remedy is the same `--add-host` every other
container already gets — the runtime accepts it with `--network host`
(verified against Docker) and mesh-host emits it for any network mode.

The refreshable-grant refresh token no longer rides a custom at-rest envelope that a
module opens with a node private key. A module is never given a node's private sealing
key, so that path could not exist -- the gap Phase C hit.
Instead the refresh token is a credential sealed to the MANAGER holder with the same
anonymous box (secrets.Seal / crypto_box_seal) every credential uses, stored as one
sealed blob, and delivered by the existing host-unseal-and-mount: the host opens it with
the node's real key and mounts the cleartext at the manager module's bound path, exactly
as a consumer's db password is delivered.
- refresh_grant now stores { sealed, manager_key }, dropping the AtRest token/wrapped_key
columns; internal/secrets/atrest.go is retired (nothing else used it).
- the licence records its manager as (node, module); KeyFor delivers the refresh token to
the manager holder and the access token to consumers, disambiguated by module so the two
can co-locate. Accept and the reseal skip the manager holder.
- the manager holder is delivered the node's PUBLIC sealing key in its bound facts, so the
module can re-seal a rotated refresh token with no private key of its own; the
declaration tolerates its empty pre-adoption secret rather than refusing.
- SubmitRefresh / set-grant take a sealed blob, never a refresh token in the clear.
The invariant holds unchanged: the control plane never reads the refresh token, and no node
but the manager holds it. A committed cross-language test proves the TypeScript module seal
opens under Go box.OpenAnonymous (the host's Unseal) -- both are NaCl crypto_box_seal.

Phase C of model-access (ADR 0050). Refresh above calls an in-process
VendorRefresher, which would open the at-rest envelope inside the control

manager node already performed -- it is given only the new access token in
the clear (sealed per holder, as any accepted key) and an opaque re-sealed

crosses this boundary. The reseal-and-publish half is extracted and shared
with Refresh, so the sealing logic is one implementation.

module-produced envelope -- adoption), submit-refresh (access token +
optional rotated envelope). Tests defend that the manager alone opens the
refresh token and the control plane never holds it in the clear.

The ADR 0050 carve-out, built generic and vendor-neutral. A refreshable-grant
licence records one manager node; that node holds the refresh token encrypted at
rest, access tokens are still sealed per holder, and the refresh token is never in
a holder's delivery. Bounded on the three stated axes: refreshable-grant vendors
only, the refresh token only, the manager node only. Anthropic's actual OAuth
refresh stays a Phase-C plug-in behind a clean seam.
- New at-rest crypto (secrets.SealAtRest/OpenAtRest): envelope encryption distinct
from the per-holder anonymous-box seal. The refresh token is under a symmetric
data key (secretbox); the data key is wrapped to the manager node's public
sealing key. The database alone holds ciphertext and a wrapped key with no
private half to open either — only the manager node reads it back.
- Refreshable-grant adapter dispatch: anthropic is now refreshable-grant,
anthropic-api-key the static-key second case. The adapter implements the
Refresher seam by delegating to an injected VendorRefresher (the Phase-C plug,
none shipped). static-key is untouched. The type assertion to Refresher is what
gates the carve-out to refreshable-grant vendors.
- Refresh lease/rotate/publish flow (Licences.Refresh): a transaction-scoped
advisory lock is the single-refresher lease; the new access token comes from the
vendor refresh, is sealed per holder (secrets.Seal, as Accept does) and delivered
on the next push — doc 13's reseal-and-publish half, all-or-nothing. The refresh
token stays put, re-encrypted at rest only if the vendor rotated it.
- Manager and refresh_grant schema: consolidated into migrations/0001 and carried
by a new incremental 0003 (the dual-write rule).
- 17 new tests, including the four security checks: KeyFor never carries the
refresh token, a static key has no manager and cannot be refreshed, the at-rest
token needs the manager's key, and a refresh delivers a new sealed access token.

ADR 0050 Phase A. Rename the licence's `provider` field to `vendor` — the
inventory already uses "provider" for which node answers a brokered provision,
and one word must not carry two facts — and route the licence layer's sealing
and delivery through a per-vendor adapter selected by that field.
The rename touches the Go struct/params/SQL in internal/licences, the operator
CLI, and the schema: 0001 (the consolidated schema) now creates the column as
`vendor`; a new guarded 0002 renames it on a database that predates the change,
and is a no-op on a fresh one.
The adapter (internal/licences/adapters) has a `shape` and the two verbs a
static-key vendor needs — accept (the generic anonymous-box seal) and deliver
(the sealed blob unchanged). refresh/identity/usage are named as optional
capability interfaces so the refreshable-grant seam exists before its code.
A registry maps vendor→shape (anthropic→static-key for now, with a Phase-B
TODO to swap it to refreshable-grant); an unknown vendor is refused clearly.
Behaviour is unchanged from the operator's view except the field name.

A consumer that requires a provision whose serves names no consumer key (redis-cache, amqp)
contributes no payload, but it still ASKS for it. ContributionsFrom keyed 'asks' on
contributions alone, so such a consumer's grant got From='' — read as withdrawn — and the
provider never created its account. redis-cache consumers (e.g. baserow) were silently
unprovisioned, tolerated only by their embedded fallback. A module asks iff it still requires
the provision, whether or not it hands anything up. Regression test added.
Found by the lavinmq AMQP provider bed (given:[] for a require-only amqp consumer); fix
lab-proven green there.

A container may declare schedule: "<cron>", the recurring twin of
run-once. The resolver already carries a resource's keys through
untouched, so schedule reaches the rendered host declaration on its own;
what belongs here is refusing, near its author, what the host would
otherwise refuse far away.
The manifest parser refuses a schedule that is not a string, one that is
not a well-formed five-field cron (cron.go: fields, ranges, *, comma,
dash, slash), and the contradictory pair run-once + schedule -- a
container runs once and gates, or on a cadence, or stays up, never two.

The provider-seal-key gate: on a node with two modules requiring the same provision (baserow
and letta both consuming postgres), sealedFor matched a need by provision NAME alone, so a
file's ${secret:X} placeholder took whichever consumer's sealed credential came last in
r.Needs -- the OTHER module's password. baserow was handed letta's password and could not
authenticate. The secrets:-map delivery path already guards this (For == m.Module, novox/hq
04-ISSUES/022); the ${secret:...} placeholder path did not. Added the same guard.
Also dedups the contributions file: when provider and consumer are co-located, grantsFor
enumerates the same-node consumer, so a consumer was emitted twice into the provider's
receives file (once full with its grant, once partial). The m.Contributes loop now skips a
(provision, module) the grants loop already carried; non-grant contributions (routes) still emit.
Regression test added: two consumers of one provision each get their own credential. Proven
end-to-end on a two-node lab install (mesh-lab assigned-two-node-db): baserow and letta on one
node, substrate on another, each authenticates with its own minted password.

A container may be marked `run-once: true` — a step the host runs to completion,
gating whatever the declaration places after it. The control plane's part is
small: the field is carried to the host unchanged (containers pass through as
maps), and the step keeps its author-order position ahead of the container it
gates, because the gate is declaration order, not a resolved dependency
(ADR 0005).
The manifest parser refuses a run-once that is not a boolean and the pair
run-once + restart-on (contradictory lifecycles) — near the manifest rather than
far away on the machine, the same lesson the action ban records. Three unit
tests; go build ./... and go test ./... green.

A node says it is there every minute and describes what it applied rarely,
and both went through Heard, which wrote every one down as a report. So a
bare alive replaced the node's last real apply with an empty one -- clearing
the declaration digest `current` is measured against, the carried ports a
push assigns around, and the clean-or-failed outcome. A node that had just
caught up read as behind within the minute, and never converged.
Whether it converged in time was a race the node's own apply set: the link's
one loop applies a declaration to completion before it can send the pending
heartbeat, so a fast apply (catalogue-small) leaves the digest standing the
~60s until the next beat -- long enough for the lab to see `current` -- while
a heavy wave whose apply outran the first beat (mongodb + unifi + marrytts)
had the alive fire milliseconds after the report and never showed `current`
at all, timing out settle even at 1200s.
Heard now returns after moving last_seen for a report that carries no account
of what the machine did -- nothing applied, nothing refused, nothing failed,
which is exactly a bare alive. A real report always carries one. This is what
the commit that began hearing alives said it did and did not: "a bare word
that a node is there moves last_seen and touches nothing else."

04-ISSUES/036: the media stack is several modules that must share the
library and download directories on one machine, but the manifest could
only say "a directory I own". Six modules each declared the same paths as
their own resources, and the resolver's duplicate-owner refusal — right
in general — would refuse the stack's only sensible assignment the first
time two of them landed on one node.
Add an `accesses` field: a pre-existing, operator-owned path a module is
granted use of but does not own (novox/hq ADR 0051). Distinct from a
`directory` resource on every axis the host acts on — the mesh creates,
chowns and reconciles a directory; it mounts an access and owns nothing.
An access is not a resource, so it never enters the duplicate-owner map
and several modules may name one path with no conflict. What is refused
is the contradiction: a path one module owns and another accesses.
Rendered into the declaration as an `access` resource, before the
container that mounts it, so the host can find it present or refuse
clearly. Unit tests cover co-resolution (the exact 036 case), the
unchanged owner-vs-owner refusal, the owner-vs-accessor refusal, and
access validation.

A module may declare a short `slug`; the mesh derives mesh_<node>_<slug|name> and
refuses at assignment (naming the slug as the remedy) when it would still overflow —
identityLimit is now 20, an S3 access key's, the tightest of the backends a login
reaches (04-ISSUES/010). The slug rides the grant so the provider derives the same
login the consumer does, even across nodes. CheckIdentity is now wired, in grantsFor.
Also, the minted secret shrinks to 40 chars (30 bytes) from 43: an S3 secret key is
8-40, the same fit-the-tightest-backend rule on the credential's other half.

CreateModuleAccount now also grants serve.<module>.* (declare, bind, consume its
own tool queues) and mesh.rpc (bind them on, publish replies) — so a module can
serve its tools and reply, scoped to exactly its own, and no other module's. The
broker tests still hold a module out of another's queue.
listens.from was a manifest constant — one value for every node a module runs
on. Now a per-node setting overrides it: {"expose": {"5432": "anywhere"}} makes
postgres public on the machine it is set for while it stays from:mesh elsewhere,
and the firewall (ADR 0050) is computed from the effective source. Exposure()
validates it — a port the module does not listen on, or a source that is not
mesh/anywhere/machine, is refused rather than reaching nothing; UnusedSettings
knows 'expose' is a real destination. Tested: default mesh, setting opens it to
anywhere, bad settings refused.
LavinMQ refuses a non-administrator declaring a queue with a dead-letter
exchange, so a scoped module cannot make its own. EnsureModuleQueue declares
<node>.<module>.events with its DLX as the mesh, and 'module issue' does so
for a consuming module — the runtime then passively checks it rather than
declaring. Verified against a real broker: the scoped account binds and
consumes the pre-declared queue.
Claude-Session: https://claude.ai/code/session_01LrgweAeERJYBg88c5cKDzF
CreateModuleAccount gives an assigned module its own broker account whose
permissions ARE its manifest: declare and read its own <node>.<module>.events
queue, read the events exchange to bind onto if it consumes, write the events
exchange only if it emits. The account name carries the node (sealed per
machine), the permissions carry the module (one cannot read another's queue).
The builder becomes one instance of this rule rather than a separate kind.
EnsureEventExchanges declares the bus the substrate owns — mesh.events,
mesh.rpc, mesh.events.dead + a retention queue — idempotently, since a module
account may not declare an exchange.
Scope tested as patterns (no broker needed), and every management call verified
against a real LavinMQ. Honest limit recorded in the code: LavinMQ has no topic
permissions, so ADR 0047's emit-origin reservation (module.<self>.*) is stamped
by the sdk, not enforced by the broker; a pure consumer like the audit logger
is unaffected.
