+
+### Decisions
+
+Decisions are logged in PROJECT.md Key Decisions table.
+
+- Sites must use nullable site_id FK (never mandatory) to preserve flat-list workflow
+- Per-client wireless data gets its own NATS stream and hypertable (not DEVICE_EVENTS or wireless_metrics)
+- Link state machine requires 3 consecutive missed polls before marking down (prevents false flapping)
+- [Phase 11]: alert_count set to 0 with TODO -- alert_events integration deferred to avoid coupling
+- [Phase 11]: Site detail page kept minimal (info + stats) -- full dashboard deferred to Phase 14
+- [Phase 11]: Used Dialog for delete confirmation (no AlertDialog component in UI library)
+
+### Pending Todos
+
+None yet.
+
+### Blockers/Concerns
+
+- OpenBao dev instance loses Transit keys on data wipe — device creds need re-entry
+- RouterOS 7 WiFi registration-table field names need validation on real hardware (Phase 12)
+- MAC-to-device resolution data source needs codebase audit (Phase 13)
