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
Add two new capabilities:
1. isUserConfirmationOfNoRemainingUncertainty(answer) — bounded,
deterministic raw-answer confirmation that no other material uncertainty
remains after a decision factor has been resolved. Matches an explicit
phrase family (e.g. 'no remaining material uncertainty', 'no other
material uncertainties remain') plus two bounded regex patterns, while
rejecting contradictory wording ('still another material uncertainty',
'I am not saying...').
2. Decision-sufficiency closure integration point in applyValidatedProposal,
positioned after post-mutation/post-propagation and before final
active-target selection. When all represented material factors are
resolved AND the raw user answer confirms sufficiency, resolves the
existing parent decision in place (status → 'resolved') and clears
the active unknown target.
Uses a virtual 'resolved this turn' set because node statuses have not
yet been reconciled at the integration point. Tests cover: exact fixture
wording from 60B.56, bounded paraphrases, absence-of-confirmation
(non-closure), remaining-factors (blockage), contradictory wording
(rejection), negated phrases (rejection), and vague completion language
(exclusion).
Implementation of Candidate B (unknown+option) from decision architecture
design in 60A.2. Adds two new primitives to the situation graph:
Schema (lib/graph/schema.js):
- SituationKind.option — a choice available within a decision context
- SituationRelationship.contained_in — links option → its parent unknown context
Prompt rules (lib/graph/prompt-builder.js):
- Section added: Decision Option Structure Rules with 5 numbered instructions
governing when/how to create option nodes, link them via contained_in,
attach consequences to specific options, and handle do-nothing alternatives.
Explicitly forbids alternative_to edges and is_baseline/is_default flags.
Tests (446 new lines):
- schema.test.js: +300 — enum completeness updates, option kind validation,
contained_in edge validation, native two-option graph fixture (~25 new tests)
- prompt-builder.test.js: +133 — focused rules verification for all 5 rule points,
negative checks (no relocation/savings/example-specific wording, no alternative_to
requirement, baseline flag prohibition context)
No production code paths affected beyond the two enum additions; existing node and
edge kinds remain unchanged. No Ollama calls, no live API calls.
Add FIXTURE_MODE=updateOnly support that bypasses Start and sends the
committed fixture (tests/fixtures/pre-anchored-update-savings-realism.json)
directly as an Update request body through production HTTP route.
scripts/reproduce-multi-turn-investigation.mjs:
- Added ESM imports for deterministic fixture loading (fs, fileURLToPath, path)
- Added FIXTURE_PATH constant pointing to committed fixture
- Added fixtureMode env-var selector and runUpdateOnlyMode() function
- Validates ANSWER_2 before any live call (zero calls if missing)
- Verifies single savings-realism anchor invariant on load
- Preserves all hardened capture fields in pre-anchored mode
- Normal-mode Start→Update chain preserved under guard clause
tests/reproduce-multi-turn-investigation.harness.test.js:
- Added 7 new harness tests for pre-anchored scenarios (46 total, all pass)
- Updated runPreAnchoredSimulation to persist rejectedProposalSnapshot on rejection
- Added runPreAnchoredSimulationWithBlock() helper
docs/:
- New docs/experiment-57j78.md with full apparatus description
- Updated docs/current-handoff.md with 57J.78 section
Add one explicit action-order rule in Additional Guidance for when
rule #6 applies to explicitly unresolved uncertainty:
1. First check whether an existing unresolved node already represents
the same uncertainty.
2. If so, update/refine that existing structure rather than creating
a duplicate.
3. If no such node exists, add a new unknown that directly represents
the unresolved uncertainty.
4. Do not use an edge alone to represent a previously unrepresented
uncertainty.
14 focused prompt tests verify: existing-first ordering, reuse path,
fallback-to-add, related-node-insufficient, edge-only-prohibited,
possibleInference separation, resolution path preserved, duplicate
contract preserved, scope uncertainty-only, fidelity/traceability
preserved, noop validator untouched, no semantic classifier added.
