Add fixture-only apparatus for representing multiple concurrent open
investigation items within a fixed case context.
New scenario 'multi-thread' exposes:
- A fixed central situation statement and case summary (product-launch
timing decision, drawn from existing pre-anchored-product-launch
data)
- Three open investigation items — none compulsory: enterprise customer
signing probability, competitor timing, financial viability comparison
- One engine recommendation (mt-ent-customer-signing, ordered first)
- User selection of any item; chosen item becomes visually primary while
others remain visible as context
- Experimental state isolated in _experimental / _experimentalState —
never aliases production graph fields
- 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
