- the idempotency arm refuses only a wrongly-asserted context; an admin
route behind unfenced requireAdmin still serves a headerless request
- the epoch trigger does not fire on a statement that names record_epoch
without moving the selector; the source guard is what covers that
- give every acceptance case a stable id and assert the mapping from a
runnable artifact, recording which cases execute in the ordinary gate
and which await the browser stage
- add the browser spec for the cases no cooperative layer can reach:
peers reconciling to an exact context, an aborted switch response, a
closed initiator, a delayed response, and the offline disk layers
- attach the asserted context to every same-origin request inside the
three fetch entries, so no call site classifies itself
- discard a response whose echoed context contradicts the adopted one;
serve one that carries no echo, which is what keeps the public poll
and every actor surface working
- adopt from /api/auth/me and the switch response, and from nothing else
- send the epoch on every switch and retry once after reconciling
- hold and reconcile on the 409 instead of leaving the record
- evaluate the fence in the wrapper above findCached, so a stale request
neither replays a body, learns a cell exists, nor inserts a claim
- return the refusal rather than throwing: one route composes the
wrapper outside apiHandler, where a throw escapes the envelope
- read the claim and the session's own context on one session lookup
- both record resolvers check the fence after authentication and before
the carrier, off the one session row that also decides the scope
- POST /api/account/switch takes an optional expectedEpoch and writes
conditionally, so concurrent switchers resolve to one outcome
- GET /api/auth/me publishes the context a browser bootstraps from
- every response that resolved a record scope echoes it back
- regenerate the API contract
- add an import-free contract module both bundles can name, holding the
header names, the parse and the verdict
- add the server fence: header read, wide-event stamp, and the refusal
- add RecordSessionChangedError as a third sibling on the existing
sharing-error arm, so the 409 needs no new serialisation branch
- add sessions.record_epoch, owned by a BEFORE UPDATE trigger so the
ON DELETE SET NULL path and raw SQL writes cannot skip it
- normalise pre-existing rows so epoch zero means never switched
- project the epoch off the row getSession already loads
- Wait for a validated account scope before warming record reads
- Abort scoped preloads and discard handoffs across record transitions
- Cover malformed scope reloads and fresh own-record recovery
- Time out stalled provider sends without unhandled late rejections\n- Record a transient timeout outcome for cascade fallback\n- Cover timeout fallback with unit and integration tests
- Exclude and erase egress claims with recipient-side lookup support\n- Serialize data wipes with managed-profile Guardian authorization\n- Cover last-Guardian and queued-claim wipe races
- Commit a final authorization claim under the lifecycle lock\n- Keep provider calls and retry outcomes outside database transactions\n- Retain authorization claims with notification delivery diagnostics
- keep shared navigation independent of actor module preferences\n- open scoped records at their first allowed destination\n- announce record access and kind in doorway names
