officer a4cf939be7 bitcoin-wallet, extracted from the platform as a plugin
Tenth plugin out, and the one whose extraction turned on a permission decision
rather than a mechanical move.

The wallet permission was kind: 'admin' — owner only, not grantable, invisible
to every other account. Plugin permissions are ALWAYS kind: 'app': mount.ts
forces it and the manifest has no field for anything else, deliberately, so
that "can a plugin escalate itself" is a question which cannot be asked. So
extraction could not preserve admin, and that was raised as a blocker before
any code moved.

It was the right change anyway, and the objection inverts. Every wallet query
is scoped by user_id, and that id comes from X-Officer-User which the platform
injects from the authenticated session — a caller cannot name someone else's.
So granting this gives an account ITS OWN wallet. Not through the API and not
with root either does it hand over anyone else's, because their seed is sealed
under a passphrase the server never stores. kind: 'admin' was single-user
thinking; grantable is how a second person gets a wallet at all.

Named bitcoin-wallet rather than wallet: it is a bitcoin wallet specifically,
and the appName drives the route, the API prefix, the table prefix and the
install key together. Tables renamed to bitcoin_wallet_* accordingly — the
prefix guard normalises the hyphen. Free only because no wallet table existed
on any server, which was checked before deciding: db:push treats a rename as a
drop plus a create.

The three custody test files moved with it and still run — 72 tests over
scrypt sealing, envelope open and bolt11. bunfig.toml's test root was widened
on 2026-08-15 after music took lyrics.test.ts and the suite silently shrank by
nine, so that trap was already closed.

68 palette classes converted, five status vocabularies hoisted into shared.ts.
Two deliberate flattenings recorded in PLUGIN.md: testnet/signet/regtest all
read as warning, and the bitcoin and lightning rails no longer differ by hue.

Deferred on purpose: watch-only data (xpubs, balances, history) stays
unencrypted so a locked wallet still shows a balance. Anyone with the database
can therefore SEE any user's balances; they can never move a coin.

// The unlock window, as a second-by-second countdown.
//
// The sidecar's `secondsRemaining` is a snapshot taken when the request was served, and re-polling once a
// second to animate a clock would be absurd. So the poll re-syncs the truth every ten seconds and this
// hook interpolates between syncs from React Query's `dataUpdatedAt`, which is the wall time the snapshot
// arrived. Drift is bounded by the poll interval and always errs towards showing LESS time than remains —
// a countdown that overstates the window is the one that surprises you mid-signature.
//
// When it reaches zero the UI flips to locked immediately rather than waiting for the next poll to agree.
// Nothing else is invalidated when that happens: every read in this app works fine against a locked
// wallet, and blowing the caches away would make an expiring timer look like a connection failure.
