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.
Adds rejectedProposalSnapshot to orchestrator diagnostics for
proposal_compatibility rejections — exposing answerMeaning (userSupportedMeaning,
possibleInference), addedNodes structural fields, addedEdges structural fields,
updatedNodes summaries, and resolvedUnknownNodeIds. Diagnostic evidence only;
does not alter validation, mutation, or error messages. Stage-gated to
proposal_compatibility only.
v0.15 duplicated the overlap helper logic in hasNodeLevelUserSupport with
reversed argument orientation (unknownText as source, userSupportedMeaning
as candidate) compared to rawAnswerSupportsUnclassifiedMeaning (USM as
source, unknownText as candidate). This produced different accept/reject
outcomes when the two texts have very different token counts.
The fix replaces the independent reconstruction with a single call to the
canonical helper, ensuring node-level and answer-meaning alignment use
identical semantics. Four boundary regression tests verify:
- Boundary A: overlap ratio < 0.4 but >= 3 shared tokens → accept (token rule)
- Boundary B: short candidate / long source accepted via structural linkage
- Boundary B control: unrelated unknown rejected with no structural edge
- Boundary C: ratio exactly at 0.4 threshold accepts via ratio rule
- Add answerMeaning schema with supportCategory and resolutionGuidance enums
- Add pre-mutation guard that validates proposal alignment with answerMeaning
- Update prompt builder to instruct the model on answerMeaning contract
- Add tests for schema, guard logic, parsing defaults, and regression cases A-D
