Heartbeat service now resolves session state per-task using agentTaskSessions, with resolveNextSessionState handling codec-based serialization and fallback to legacy sessionId. Queued runs are chained — when a run finishes or is reaped, the next queued run for the same agent starts automatically. Queued runs for an agent with an already-running run wait instead of failing. Add task-sessions list endpoint and extend reset-session to accept optional taskKey for targeted session clearing. Block pending_approval agents from API key auth. Update agent/company delete cascades to include task sessions. Update spec docs with task-session architecture. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
