Adds deriveInvestigationLearning to episode-preparation.js: pure function that maps resolvedNodeIds + Contributions + Findings to investigation learning propositions, preserving node.label question text and contribution-provenance ordering.
Owning tests prove: correct provenance, cross-question isolation, eligibility rule (null/agree eligible; not_quite/not_relevant excluded), unresolved exclusion, no-eligible-material omission, text preservation, and provenance authority over originatingTargetNodeId shortcut.
- Zod validator: plausibleInterpretations accepts empty string (zero interpretations) while remaining required and string-typed
- Prompt instruction: SECTION B now explicitly requests "" instead of absence prose when no plausible inputs exist
- Report generation/update paths derive hasPlausibleInterpretations from actual synthesized data rather than hard-coding true
- Tests: updated validation contract, added hasPlausibleInterpretations derivation assertions, updated seam tests to use derived values
synthesizeInvestigationOverview() called provider.generateReconstruction(prompt, modelName)
without an output contract. Without a structured-output schema the provider defaults to its
initial-reconstruction format which lacks { understanding, plausibleInterpretations }, causing
'Missing or invalid required fields' validation failure.
Add overviewOutputSchema (JSON-schema matching validateOverviewResponse contract) and pass as
third argument, matching the proven pattern in synthesizeCurrentUnderstanding().
53/53 tests PASS. Co-Authored-By: Claude Code <noreply@anthropic.com>
Production: synthesizeInvestigationOverview() now passes providerResult.response
to validateOverviewResponse() instead of the raw envelope, matching the proven
pattern in current-understanding-synthesis.js.
Regression: fakeProvider returns real-provider envelope shape { response, providerApiPath }
and four new regression tests verify unwrapping succeeds with valid response
and fails correctly with invalid response inside the envelope.
Handoff: documented defect confirmed, fix applied, and owning regression added.
- reconcileDecisionClosureOwnership normaliser between reconciliation and validation (Boundary B)
- Strips terminal parent updates without explicit user confirmation; preserves all other proposal work
- Strips parent from resolvedUnknownNodeIds bookkeeping on no-confirmation strip
- Restores reconciler-forced resolved→unknown for synthetic updates too
- Prevents hybrid unknown+value states by nulling newValue in all stripping paths
- No-op update created when reconciler synthesized the entry to prevent downstream errors
Prompt:
- Rule #143 rewritten from evidence-sufficiency to explicit-confirmation gate
- Directs model to use possibleInference for directional conclusions when confirmation absent
Regression preservation:
- 60B.43 lifecycle invariant restored via explicit confirmation phrases in fixture answers
- 60B.49 reconciliation auto-add invariant restored under confirmed closure flow
- Test apparatus fixed: structuralActionRequired required with userSupportedMeaning (validator constraint)
New coverage:
- 10 tests for all 60B.79/80 coverage requirements
- 5 prompt alignment tests for Rule #143
