- Google Meet: keep Chrome realtime transport tests hermetic on Linux prerelease shards while preserving the macOS-only runtime guard. Thanks @vincentkoc.

- QA/Slack: fail the live mention-gating scenario on any unexpected SUT reply, even when the reply does not echo the expected marker. Thanks @vincentkoc.

- QA/Matrix: steer the live tool-progress preview check away from `HEARTBEAT.md` and report final preview candidates when the live marker reply misses the exact token. Thanks @vincentkoc.

- QA/Matrix: let the live tool-progress preview and error checks verify progress replacement events without depending on the preview saying `Working`, `tool: read`, or unlabelled `read from`. Thanks @vincentkoc.

- QA/Matrix: let the live tool-progress preview and error checks verify progress replacement events without depending on the preview saying `Working`, `tool: read`, or an unlabelled/pathless `read from`. Thanks @vincentkoc.

- QA/Matrix: wait for live approval reactions to echo before starting the threaded approval decision timeout. Thanks @vincentkoc.

- QA/Matrix: reuse the primed driver sync stream when confirming approval reaction echoes, avoiding missed self-reactions in live release runs. Thanks @vincentkoc.

- Tlon: expose `groupInviteAllowlist` in the channel config schema and clarify that group invite auto-accept fails closed without an invite allowlist. Thanks @vincentkoc.
