Contracts 0.81.0: opaque event cursors beside the global seq (plan T7, ADR-042): publish-result carries a cursor per stored event, read-result a cursor per event, next_cursor per page and a cursor on a single event; seq stays for one release. Fixtures for both; 14358 checks; compat vs v0.80.0: no breaking changes.

++## 0.81.0 — 2026-09-29
++
++**Opaque cursors beside the global seq** (plan T7, ADR-042, additive).
++- `events.publish-result@1` gains an optional `cursor` per stored event; `events.read-result@1` gains `cursor` per
++  event, `next_cursor` per page and `cursor` on a single event. A cursor is opaque (a position plus a retention epoch):
++  hand it back as `after=` or `Last-Event-ID`, never parse it. Events returns both `seq` and `cursor` for one release,
++  then `seq`, `next_after_seq`, `latest_seq` and the global-order promise go.
++- ADR-042 (the events fabric) is recorded in docs/adr.
++
  ## 0.80.0 — 2026-09-29
  
  **`chat.moderation.read`: how Live reads the chat tables Chat owns** (plan T3, the six staged tables).
