Establishes reusable apparatus for asking: given scenario text X,
what structured initial decomposition does current production path produce?
- Direct curl/Postman via existing /api/cases/start route (no new API)
- Thin CJS helper at scripts/start-case-experiment-helper.cjs for Claude
experiments (imports startCase directly, zero code duplication)
- Zero-live-call verification: all four seam checks confirmed by existing
tests (cases-start-route.test.js, start-case-summary.test.js)
- No browser state, no persistence mutation, no Investigation ID required
by the route itself

Replace Portfolio's static "+ Create new investigation" link (href:
/investigations/case-1) with a <button> that allocates an opaque
application-owned durable ID via crypto.randomUUID() and navigates
via router.push to /investigations/{id} without persisting any empty
Investigation.
INVESTIGATION_ID constant retained only for card links (Continue
investigation / View report) — not migrated in this increment.
Test: deterministic Create New activation test verifies UUID allocation,
navigation to generated ID route, and zero saveInvestigation calls.
Migrate the Investigation page route to own durable investigation identity
via its route [id] segment, passing that ID through to ScenarioForm for
hydration and persistence.
- Remove hardcoded INVESTIGATION_ID constant from page.jsx
- Use params.id as routeId; loadInvestigation(routeId) loads by identity
- Pass investigationId prop into ScenarioForm in both branch paths
- Session restore calls loadInvestigation(investigationId)
- All 4 save call sites include id: investigationId in snapshot
- Missing identified Investigation starts clean (no singleton fallback)
- Legacy singleton is not migrated/fallback-loaded
- Portfolio remains unmigrated; Report remains unmigrated; Restart untouched
Deterministic tests: 34/34 pass (scenario-form-persistence + investigation-storage)
Build: PASS
Live Playwright: all criteria verified at /investigations/v060e-live
Replace bare re-export in investigation-storage.js with explicit wrapper
functions that own the canonical identity contract: snapshot.id is the sole
save identity authority. The provider never allocates or changes IDs.
7 new deterministic tests prove: identified snapshots persist under their
own id key, explicit competing id arguments are ignored, A/B remain
independently addressable, unknown IDs return null, and legacy singleton
compatibility is preserved for unmigrated callers.
No application callers modified. UI/routes not migrated.
- loadInvestigation(id) selects by durable ID when provided, null for unknown
- saveInvestigation(snapshot, id) persists under provider-chosen key derived from id
- clearInvestigation(id) removes specific investigation by identity when provided
- localStorage representation: confidence-engine-investigation:<durable-id>
- Backward-compatible singleton path preserved for existing unmigrated callers
- 6 new targeted tests proving two independently addressable Investigations
Replace flex-row View report + status with flex-col stack so the
freshness label sits below the button and no longer floats between
actions on the Portfolio.
v0.59b — Report page freshness UI:
- Shows Current / Update available beside the generated report
- Manual Update report action with duplicate prevention guard
- Explanation copy about investigation changes since generation
- Persists generatedFromRevision during update flow
v0.59c — Portfolio Report freshness state:
- Surfaces Current / Update available alongside existing View report link
- Derives solely from revision provenance (zero model calls)
- No Update report action on Portfolio (manual update owned by Report page)
- Neither state shown when no Report exists
- Updated makeSnapshot with investigationRevision for realistic test data
