S00-016: Approve recovered reviewer availability after fresh QA tool checks

Changes: Accept only S00-016 readiness and add independent QA evidence after verifying coordinator release, executor patch and fresh reviewer tool use.
Validation: Read-only readiness assertions passed; tasks.py validate passed for 281 tasks at revision 30; git diff --check passed. Verified distinct same-model sessions and preserved parent acceptance boundaries. Future provider capacity and parent implementation reviews remain separate.

Status: done
