+# TODOS
+
+## P1 — Ship with Phase 1
+
+### v2.0 Architecture Document Update
+Update `bastion/docs/ARCHITECTURE.md` to cover v2.0: driver model, fleet system,
+Pulumi integration, Vault secrets, Deno evaluator, new CLI grammar. The existing
+doc covers v1.0 comprehensively (432 lines). v2.0 adds 5+ major subsystems.
+**Effort:** M (human: 1 week / CC: 1-2 days)
+**Depends on:** Phase 1 complete
+**Source:** CEO review 2026-04-01
+
+## P2 — Post-v2.0 Core
+
+### SSH Emergency Mode (scoped)
+SSH-based operations limited to: (1) earliest necessary box provisioning before agent
+is installed, and (2) emergency debugging/fixing operations that can't be done via agent.
+NOT a general-purpose DeploymentTarget alternative. The v1.0 `recheck` and `fix-ssh-root.sh`
+patterns are the model. Agent stays the primary management path.
+**Effort:** S (human: 1 week / CC: 1 day)
+**Depends on:** Phase 2 complete (DeploymentTarget interface exists)
+**Source:** CEO review 2026-04-01
+
+### Prometheus Metrics Endpoint
+Add `/metrics` endpoint to labd: resource counts by status, apply duration histograms,
+driver operation latency, fleet pipeline completion rates. Standard Prometheus scraping
+for Grafana dashboards and alerting.
+**Effort:** S (human: 2-3 days / CC: 2-3 hours)
+**Depends on:** Phase 1 (labd exists with resource store)
+**Source:** CEO review 2026-04-01 (observability gap)
+
+## P3 — Future Enhancements
+
+### Infrastructure Graph Visualization
+Visual representation of resource dependencies, environment topology, fleet status.
+Could be a web UI or terminal-based (like `kubectl tree`).
+**Source:** CEO review 2026-04-01
+
+### `labctl import` for Existing Cloud Resources
+Discover and import existing AWS/GCP resources into the state store.
+Pulumi's import functionality could be leveraged.
+**Source:** CEO review 2026-04-01
+
+### Built-in Secrets Rotation
+Automatic rotation of managed secrets (database passwords, API keys).
+Vault handles rotation but a labctl-native workflow could simplify.
