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
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.
- Empty Done immediate transition now sets node.status to resolved
alongside resolvedNodeIds/doneForNowIds — same canonical parked
shape as populated Done (no server call required)
- Clarified-question Re-open removes target from doneForNowIds so
the question visibly returns to Open Questions
- Immediate graph mutation creates new node objects immutably
(React state semantics), touching only the target node
Adopt executeEpisodeDone orchestration as the canonical path for
'Done for now' activity boundary: one user Done triggers exactly
prepareCompletedEpisode -> reconsiderCompletedEpisode -> applyValidatedProposal
-> Current Understanding synthesis -> leave focused workspace.
Production changes (components/scenario-form.jsx):
- Add prepareCompletedEpisode, reconsiderCompletedEpisode, applyValidatedProposal imports
- Export executeEpisodeDone({params}) with all 4 domain functions as named
parameters (defaults to module exports) for deterministic test wiring
- Rewrite handleDoneForNowPromotion(targetNodeId) as async: delegates to
executeEpisodeDone pipeline; CU synthesis installed only on success
- Add doneInProgressRef useRef(false) for exactly-once Done enforcement
- On synthesis failure: KEEP updated graph, KEEP Findings, KEEP existing CU
- Retire produceFindingInformedSummary from ScenarioForm (legacy CU writer)
- Remove legacy idempotence guard and Evidence:[] regex dedup
Test changes (tests/ui/scenario-form-episode-done.test.jsx):
- 9 tests verifying orchestration pipeline correctness:
1. Successful path order: prepare -> reconsider -> apply -> synthesis
2. Correct prepared episode input parameters
3. Structured application evidence (no answer fields in context)
4. nextGraph used for synthesis (not stale result state)
5. Reasoning failure: apply not called, CU synthesis not called
6. Application failure: CU synthesis not called, graph not replaced
7. Synthesis failure: nextGraph remains installed (no rollback)
8. Exactly-once per call for each domain function
9. Legacy Done writer retired (pipeline does not produce deterministic summary)
Architecture: after successful /api/cases/update, derive explicit nextGraph +
nextFindings, call synthesizeFromFindings exactly once, replace Current
Understanding with reconstruction result.
Key invariants:
- outcome.summary retired as final CU authority → always synthesis reconstruction
- Explicit derived state (no React-state reread) for graph and findings
- Previous CU preserved on synthesis failure (no fallback to outcome.summary)
- Graph and Findings NOT lost on synthesis failure
- saveInvestigation persistence uses currentUnderstanding, not outcome.summary
Deterministic regression: 7 tests (Cases A-E + 2 edges) covering all rules.
Files: components/scenario-form.jsx, tests/ui/scenario-form-case-update-synthesis.test.jsx
Verified: deriveFindingsFromContributions() exists with passing tests but
is never called in production. The contributions → findings seam is un-wired:
1. handleDeconstructSubmit() sends contribution to ScenarioForm
2. appendFocusedContribution() stores it in focusedContributions[]
3. findings state stays [] — no derivation ever runs
4. empty findings sent to /api/cases/update (which only echoes them back)
5. nothing renders from the findings surface
Fix: call deriveFindingsFromContributions after contribution is appended.
- Add focusedContributions state + appendFocusedContribution callback in ScenarioForm
- Contributions persist through session lifecycle (save/restore/restart)
- Pass onFocusedContribution and focusedContributions to ReasoningWorkspace
- Call onFocusedContribution on successful deconstruct with full result shape
- Test: contribution sequence, field preservation, same/different target coexistence
Emphasise the active investigation card through stronger elevation,
clearer borders, and improved spacing. Quiet supporting panels by
reducing border opacity, softening heading weight, and lowering
text contrast — making them available without competing for attention.
Facilitator card receives a warm surface tint to read as a briefing
card rather than a generic panel.
Documentation: close experiment 05 with findings, add experiment 06
to the design evolution log, add Attention Hierarchy to UX guidelines,
defer dark mode to a future Investigation Mode experiment.
Presentation changes only — no reasoning, prompts, graph, API, or
backend modifications.
