+# Task 1 Implementation Report
+
+## Scope
+
+Implemented the canonical defense rehearsal route manifest and documentation
+from `task-1-brief.md`.
+
+- Added `scripts/presentation-rehearsal-routes.json` with all 42 current
+  `mainScenes` scene/beat pairs. Each object has exactly `sceneId`, `beatId`,
+  `route`, and `fileStem`.
+- Added `docs/runbooks/presentation-rehearsal-matrix.md` with one row per route,
+  including the presenter sentence, dominant/supporting visuals, chat mode,
+  evidence mode, and exact fallback route.
+- Linked the matrix from `docs/runbooks/defense-presentation.md` and explicitly
+  described it as a rehearsal checklist rather than a new story or product
+  contract.
+- Extended `storyboard-navigation.test.ts` to validate unique and complete
+  bidirectional coverage against `mainScenes`, exact manifest keys, canonical
+  route fields, and hash round-trips through `hashForLocation` and
+  `locationFromHash`.
+
+## Verification
+
+The test-first check was performed before creating the manifest: the focused
+Vitest suite failed with an import-resolution error because
+`scripts/presentation-rehearsal-routes.json` did not exist. After adding the
+manifest, the same suite passed.
+
+Exact verification commands and results:
+
+```text
+pnpm --dir web/apps/console test -- src/presentation/storyboard-navigation.test.ts
+PASS: 1 test file, 11 tests
+
+pnpm --dir web/apps/console typecheck
+PASS: tsc -b --pretty false
+
+PowerShell JSON validation using ConvertFrom-Json
+PASS: manifest entries: 42
+PASS: manifest keys: beatId, fileStem, route, sceneId
+
+PowerShell matrix row count
+PASS: matrix route rows: 42
+
+git diff --check
+PASS: no whitespace errors; Git reported only LF-to-CRLF normalization warnings
+```
+
+## Self-Review
+
+- The manifest uses the current `mainScenes` IDs, including `approval`,
+  `resume-output-evidence`, and `conclusion/questions`; no historical
+  interrupt-evidence or workflow-demo route names were introduced.
+- The coverage test fails on a missing beat with its scene ID and rejects stale
+  manifest entries, duplicate pairs, incorrect canonical route strings, and
+  malformed navigation round-trips.
+- Matrix evidence references remain bounded by existing storyboard pointers,
+  prepared replay evidence, and the defense runbook fallback wording. No
+  expected output was invented.
+- All current scene beats use `hidden` chat mode in the storyboard metadata, so
+  the matrix records `hidden` consistently rather than inventing full, rail, or
+  dock modes.
+
+## Deviations And Concerns
+
+No functional deviations from the brief. The repository emits line-ending
+normalization warnings for the touched text files during Git operations; these
+are not whitespace errors and do not affect the committed content.
