# Task Board — Milestone T1: Production Hardening

**Submilestone:** T1 (Error recovery, observability, metrics, reliability)

| ID | Scope | Status | Branch | Verification |
|----|-------|--------|--------|--------------|
| T1.1 | Workflow error recovery: retry policies, deadletter handling, graceful shutdown | [x] | `task/T1.1` | Simulate orchestrator crash mid-cycle, resume without data loss |
| T1.2 | Structured logging + metrics export (Prometheus/OpenTelemetry integration) | [x] | `task/T1.2` | Metrics visible in homelab Grafana, logs queryable in Loki |
| T1.3 | Activity timeout tuning automation: learn from historical failures, recommend overrides | [x] | `task/T1.3` | Planner reads lessons file, suggests `update-tuning` signal based on patterns |
| T1.4 | Board state validation: detect corruption, auto-heal from board divergence | [x] | `task/T1.4` | Corrupt board file recovered without manual intervention |
| T1.5 | Workflow pause/resume with state snapshot: serialize mid-cycle state to persistent store | [x] | `task/T1.5` | Pause signal, restart pod, resume signal → workflow continues from exact point |
| T1.6 | Comprehensive integration tests: multi-pod concurrency, network flakiness simulation | [x] | `task/T1.6` | Concurrent orchestrator instances on shared repo pass e2e without conflicts |
| T1.7 | Audit logging: all planner decisions, judge verdicts, implementer changes logged immutably | [x] | `task/T1.7` | Audit log persists across workflow restarts, queryable by task/timestamp |
| T1.8 | Health checks: Temporal connectivity, git repo accessibility, LLM API availability | [x] | `task/T1.8` | Periodic health probes, liveness/readiness endpoints for K8s |

## Submission Criteria
All T1.1–T1.8 marked `[x]` → submilestone complete → squash-merge `task/T1.*` to main.
