From review: the export counted any operator-sealed row as recoverable, so a
secret sealed to a replaced key was reported as openable with the current one;
replacing the key counted orphans in one table of two; and a pair credential
held from two providers was recovered as whichever row came first. The export
now lists what the current key opens, what an earlier key opens, and what has
no copy; `secret recover` takes --provider and refuses ambiguity; files that
must not exist are created exclusively; one constructor builds the export for
the operator's file and the vault's disk alike.
novox/hq ADR 0085, amended: the mesh's root secrets — the store's superuser,
the broker's administrator, every secret a module holds for itself — were
sealed to a node key and nothing else, so a lost node took them with it.
Now the mesh records an operator's public sealing key and seals every own
secret to it as well, minted or accepted. The private half is written once
by `operator key new` to a file the operator keeps off the mesh; the mesh
holds one more blob per secret that it cannot open.
`secret recover` opens a secret with that key, to a 0600 file, from the
store or from an export; `secret export` writes every operator-sealed copy
as ciphertext. A module that `keeps` (the vault) is handed that export as a
declared file on its own disk, so recovery survives the store.
Secrets made before the key exists have no operator copy and are said so —
the plaintext was discarded — until each is issued again.
One name per thing, per the HQ glossary: the module/container/image/binary/repo
becomes mesh-controller, the seat the-controller, and the store+broker pair the
foundation (embedded base bundles, default template and example lock renamed with
their go:embed directives). No behaviour change — a pure vocabulary rename.

The manager module's seal now runs over the audited tweetnacl-sealedbox-js (mesh-catalog
anthropic-manager) rather than a hand-transcribed NaCl. Regenerate the fixture's sealed value
from that new seal() over the same node key pair and plaintext, so the fixture is the new
library's output. crypto_box_seal is randomised, so the blob differs; the wire format does
not. TestModuleSealedBoxOpensInGo still opens it under box.OpenAnonymous and recovers the
plaintext, proving TS(tweetnacl-sealedbox-js) to Go interop.

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.

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.

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.

The last of the four gaps ADR 0024 names. Everything the mesh handles
today it generated itself, sealed to both ends, and discarded. An API key
for a hosted service comes from a person, and carrying it needs a verb
the mesh did not have.
Accept seals it on the way in and keeps no plaintext — the same storage
and the same property as a generated one, only a different origin. That
is the whole difference from the arrangement being replaced, where an
operator-supplied key sits in a column the control plane can read, which
makes a copy of the database a copy of every account the mesh touches.
The consequence is deliberate: the mesh cannot show it back. Somebody who
loses the key gets a new one from wherever it came from. There is no
reveal and there cannot be one, because a mesh that can reveal a secret
is a mesh that holds it — asserted as a test, because it is a property
somebody will eventually ask to break.
An empty value is refused. A credential that exists, authenticates
nowhere and looks exactly like a working one is the failure this whole
mechanism is arranged to prevent.
HAL keeps env vars in the registry, encrypted at rest. Its own tooling
records what that bought and what it did not. `secret_locate` matches by
value rather than by name — because the same password sits in
mesh_provisions, in module_env, in each node's .env in plain text, and
inside every connection string composed from it, and its documentation
says those URL copies "are often the only copies actually in use". And a
query against the encrypted column returns zero rows and proves nothing,
so auditing moved to the decrypted copies on the nodes.
Two faults there, and encryption at rest addresses neither: the control
plane can read what it stores, so a copy of the database is a copy of
every credential; and one secret has many homes with nothing tracking
them.
So here the mesh generates a password, seals it to each end with keys
those nodes generated, stores both blobs, and discards the plaintext. It
cannot read what it holds. Neither can the broker relaying it. And
nothing is composed centrally — a connection string is assembled on the
machine that needs one — so no copy is ever minted in a shape nothing
tracks. `Compromise of a node is compromise of that node` (ADR 0004) is
now true of secrets, not only of identity.
Two files rather than one, because the mesh cannot compose a document
containing a value it discarded: `binds` carries the readable facts,
`secrets` carries the credential alone. The readable half stays readable
in the declaration; the secret half changes only when the secret does,
which makes restart-on precise. The provider gets a directory, one file
per consumer, for the same reason.
It is made once and kept — regenerating per declaration would restart
both ends on every push, and the password a provider was told to create
would never be the one its consumer was given. It is remade when either
end's sealing key changes, and both ends learn the new one in the same
push, so there is no window where half the mesh holds a dead credential.
Two tests found passing for the wrong reason, both caught because their
injection came back clean:
- the provider's copy was asserted non-empty, which reads the same
whichever column is selected. It now opens the blob with the
provider's own key.
- RotateSecret deleted and re-created; the re-create was dead, because
the next read makes one anyway. Removed, and a second path to the same
act is how two ends come to disagree.
And one real fault: three places built a declaration, and the one behind
`--json` predated credentials, so it silently produced a declaration
missing them — a difference between what `plan` showed and what anything
reading `--json` got. There is one path now.
