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.
