+- **REQ-201** — Metrics store backup/restore doc: `metrics/README.md`
+  documents regenerable vs append-only artifacts + restore procedure.
+  (Phase P2)
+- **REQ-202** — Metrics glossary appendix slide: the unified deck has a
+  "Metrics Glossary" appendix slide with one-line KPI definitions +
+  grounding badges. (Phase P5)
+- **REQ-203** — "What's Deferred — and Why" slide: the unified deck has
+  a slide pairing each of 8 deferred metrics with its blocking decision
+  ID. (Phase P5)
+- **REQ-204** — NORTH_STAR diff-check in CI: `run_ci.sh` includes
+  `check_north_star_diff` that fails when Vision/Objectives/Anti-Goals/
+  Targets sections change without a `NORTH_STAR-CHANGE:` commit trailer.

+  supports `query`, `verify-chain`, `stats`, `export`, `replay`;
+  `verify-chain` detects broken hashes; `replay` prints ordered events;
+  tests pass offline. (Phase P2)

+  screenshot. (Phase P3)
+- **REQ-209** — PowerBI column-level data dictionary: `docs/METRICS_VIEWS.md`
+  has a per-column data-dictionary table (column, type, source/formula,
+  unit, grounded/derived/deferred status). (Phase P3/P4)
