One registry line — `"openai": StaticKey`. The generic static-key adapter
already serves any vendor (accept is the vendor-independent seal, deliver is the
value unchanged, and refresh/identity/usage are not implemented), so a second
static-key vendor is data, not code. The shape-selection test now asserts
For("openai") reports static-key.

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.

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.
