The pending-roster finding is fixed in 3afeb32: a ninth distinct participant now evicts the oldest roster entry while accepted and terminal events retain priority. The old-source regression failed with the newest participant missing and passes with the newest eight retained. The issuing-key documentation also states the six scopes required for client-token minting, session rules, and browser call tokens. Focused Calls tests, typecheck, lint, format, and diff checks pass. The producer snapshot refresh remains intentionally pending until the final merged TURN producer SHA. @coderabbitai review |

The six delegation scopes are documented for both token-mint paths. I used the prior webhook contract guidance. The producer snapshot refresh remains required before merge, after the final merged producer SHA is available. One check does not pass for the complete PR. ✏️ Learnings added

1 participant
Browser WebRTC calls received invitation responses but could not observe later participant joins, state changes, or departures. External-media call models now consume the scoped lifecycle roster events; socket-media calls retain their media control stream. The TypeScript webhook catalog exposes matching payload types plus terminal call-ended and telemetry events. Recovered terminal events preserve an explicitly nullable caller identity; telemetry retains cumulative kilobit units.
Delayed invitation replies cannot overwrite newer roster state or revive participants after departure or call end. Duplicate updates are deduplicated, authoritative state changes are preserved, and a later explicit re-invite remains possible. The existing UI design is unchanged. READMEs and Unreleased notes document behavior and the reserved false media flags.
Depends on the runtime event producer in polymorfa/polymorfa#135 and the terminal contract in polymorfa/polymorfa#137. Packages remain unpublished; refresh the exact merged-runtime contract snapshot before merging this SDK change.
Validation: 361 tests, workspace builds, TypeScript checks, lint, formatting, retired-name and strict coverage checks pass. Four initial roster/ordering regressions and seven review regressions fail against the prior implementation. Buffered roster traffic cannot displace accepted or terminal call events. Signed terminal-event fixtures fail against the old event catalog and pass after the fix. Root/workspace package dry runs and production dependency audit pass.
