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
- FocusedQuestionBody derives thread-local contribution subset using
targetNodeId || originatingTargetNodeId matching
- hasCompletedContext, latest completed contrib, and all effective
presentation fallbacks use scoped collection only
- scenario-wide focusedContributions history preserved in memory
- Fresh Question B no longer bleeds Question A's content across
every presentation surface (Previously answered, What this tells us,
Still unclear, Questions this raises, Assumptions, Connections)
- Reopening or revisiting Question A still uses its own history
- Targeted regression: 3 new Vitest cases pass
- Handoff docs updated with v0.52 correction record
Move the milestone invitation from after Clarified Questions to occupy
the same spatial position as Open Questions — between Current Understanding
and Questions we have clarified. Uses ternary: openUnknowns > 0 ? OpenQuestionsUI : milestoneAllowed ? MilestoneInvitation : null, followed by ClarifiedQuestionsUI unconditionally. No duplication of clarified cards or Re-open controls.
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.

Repair LOCATION-A defect where processing feedback rendered near the
completed narrative instead of inside the active follow-up block.
Changes:
- components/reasoning-workspace.jsx: three targeted edits using a single
spinner component with conditional rendering; hasActiveFollowUp routes
ownership to the correct container
- tests/open-questions-vs-assumptions.test.jsx: regression test confirming
exactly one indicator, DOM child of follow-up-block, ownership separation
Accepted criteria met:
✅ Exactly one processing indicator during follow-up processing
✅ Indicator is a DOM child of follow-up-block
✅ Top-level indicator suppressed when follow-up active
✅ Initial answer flow preserved (top-level when no follow-up)
✅ Successful follow-up promotion intact
✅ All existing context retained
✅ No new state/lifecycle changes/error redesign
When a reopened completed turn is displayed, distinguish it from an active question:
- 'PREVIOUSLY ANSWERED' + 'YOUR RESPONSE' headings for completed turns (hasAnswer=true)
- Bare 'QUESTION' heading preserved for active follow-ups (answer=null)
- Verbatim user answer rendered under its own heading — never conflated with Engine-derived findings
- Causal narrative: Question → Your response → What this tells us
Gate results:
- 102 tests passed (78 existing + 24 new v0.49 provenance narrative tests)
- Clean production build
- Live verification on localhost:3000 confirmed correct rendering
ThreadContributionsBadge, PriorContributionsSummary, and
SecondaryPreviousLearning all filtered contributions via
c.targetNodeId === nodeId. Multi-turn follow-up Contributions carry a
different immediate targetNodeId while the canonical origin remains on
Findings (originatingTargetNodeId).
Repaired: all contribution filters now match on EITHER
c.targetNodeId === nodeId || c.originatingTargetNodeId === nodeId.
handleDeconstructSubmit carries originatingTargetNodeId from
focusedPresentationItemId as provenance for cold-return recovery.
