Surfaced during PR #596 blind review (architect-F3).
Problem: STATE_FILE path is ~/.claude/teams/{team_name}/inbox-wake-state.json. Concurrent sessions on the same project that share a team_name (rare, but possible via pause/resume deserialization) would share the STATE_FILE, creating a race condition.
Practical reachability: most concrete failure shape is pause→resume, which is sequential not concurrent. The α₂ atomic-rename design handles this cleanly (new session writes STATE_FILE → atomic-rename replaces old; old monitor_task_id ignored). Truly concurrent same-team-name requires the user to manually orchestrate it — rare.
Why deferred: existing α₂ design handles the practical case. Truly concurrent edge would require adding session-id namespace to STATE_FILE path, which touches every callsite (cron prompt body, Monitor block, teardown, runbook) for an edge that's hard to reach.
Suggested fix scope: add session_id to placeholder convention; STATE_FILE path becomes ~/.claude/teams/{team_name}/inbox-wake-state-{session_id}.json. Substantial design change.
