+# MinerOps v0.4: Monitoring
+
+## Status
+
+Planning document. The version label and candidate scope are provisional and do
+not override the current version summary in `README.md` or phase ordering in
+`docs/ROADMAP.md`.
+
+## Goal
+
+Provide reliable current-state and historical visibility across the fleet.
+
+## Candidate Scope
+
+- [ ] Configurable discovery
+- [ ] MAC-based asset reconciliation
+- [ ] Miner status and telemetry
+- [ ] Historical retention
+- [ ] Fleet dashboard
+- [ ] Room, rack, model, and electrical summaries
+- [ ] Alert generation and lifecycle
+- [ ] Notification integrations
+
+Discovery and network reconciliation depend on the roadmap's Inventory &
+Identity phase, while electrical summaries depend on Infrastructure. Their
+presence here does not change those dependencies.
+
+The repository already contains early-stage discovery, telemetry, retention,
+dashboard, and infrastructure-summary foundations. Unchecked items describe
+work needed for a coherent, supported monitoring product rather than an absence
+of related implementation.
+
+## Definition of Done
+
+Observations remain distinct from authoritative inventory, stale data is
+explicit, discovery does not blindly create assets, retention is documented,
+alerts are auditable, and monitoring failures cannot corrupt inventory or
+repair history.
