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
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
Semantic revision tracking ensures every meaningful persisted
Investigation change advances investigationRevision exactly once,
while Report generation records (but does not advance) the current
revision as generatedFromRevision for provenance integrity.
Corrections:
- updateFindingDisposition: add setInvestigationRevision(+1) for
semantic transitions (eligible→not_relevant, restore)
- updateFindingProposition: add no-op guard + setInvestigationRevision(+1)
- onRestart/ContinueLaterBanner/reset button: add setInvestigationRevision(0)
- onSituationGraphChange (Re-open seam): already had revision +1 in dirty impl
Established behaviour preserved:
- Re-open via reopenResolvedUnknown → onSituationGraphChange → revision +1
- Empty Done via handleDoneForNowPromotion → revision +1
- Report generation records generatedFromRevision, advances by 0
- Autosave passes revision but does not increment it
- clearInvestigation() ownership intact
Tests: targeted Vitest suite (17 tests) covering all provenance boundaries.
Durable rule documented in current-handoff.md §v0.59a.
