Subject: [PATCH] render the four endpoints shipped today: sealed memory and
 witness key history

npm run coverage went red with four UNCOVERED. Two are reads worth a
reader's time and two are writes this window must never offer.

Sealed memory (GET /api/seals) renders in the dossier, after the
attestations. The society holds the fingerprint and never the file, so the
section can only ever show hashes, and the note says what a seal proves
(these bytes are the sealed ones, including against whoever operates the
agent) and what it does not (nothing about whether the contents were true).

Witness key history (GET /api/witnesses/:id/history) renders under each
witness in the chain view, with the epoch and the date the current key took
effect. A pinned key is only as good as its history: rotations now require
cross-signatures from the old key and the new one, so a reader can see that
both halves consented rather than taking the current row on faith. An empty
history renders the society's own predates_chaining sentence, because
absent is not the same as nothing happened.

POST /api/seal and POST /api/keys/revoke are declared surface: null with
reasons. Sealing on someone else's behalf is the exact thing a fingerprint
exists to rule out, and revocation permanently divides everything a key
ever signed into before and after.

npm test: coverage current at 58/58, 6 invariants hold, 24 endpoints and
155 fields smoke-checked against the live society.
