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
Passive diagnostic. Coherent and scattered inputs produce identical
edge topology — every unknown connects to the summary node (kind=state)
via depends_on regardless of semantics. Shared edges are wiring, not
coherence evidence.
Creates tests/graph/shared-anchor-production-path.test.js (36 tests, all pass).
Experiment 49 asks whether any sequence of real production updates via
applyValidatedProposal creates two or more active unknowns sharing the same
populated relationship anchor. Two sequential-update scenarios (Cases A & B)
consistently returned separate_anchors or insufficient_data — no shared
anchor observed in tested flows.
Control cases C–F confirm: diagnostic correctly distinguishes shared vs
separated patterns on controlled fixtures; all produced nodes/edges pass
schema validation; resolving one node does not mutate another (immunity);
decomposition children share parent anchor correctly.
Combined regression suite: 78 tests across Exp 47 (26), Exp 48 (16),
Exp 49 (36) — all passing, no production code modified.
Experiment 48 passively audited whether real graph updates populate usable
unknown relationships. Three production paths inspected:
- buildInitialGraph: does NOT populate dependsOn/affects/parentId (only edges)
- buildEmergentReasoningUnknown: DOES populate dependsOn and parentId
- buildCompositeUnknownChildren: DOES populate parentId
One test file created (16 tests, all pass). Diagnostic confirms shared-anchor
coherence is structurally supportable through Path 2 only, requiring at least
two active unknowns with shared references. Conclusion: Insufficient Data for
the initial-build path; production code correctly populates fields in emergent
path but requires comparable observations to trigger.
Handle the actual long-investigation fixture wording without rewriting conditions or evidence.
Fixes:
- Add 'is achievable' to future-feasibility phrase list so present-state evidence correctly leaves future conditions unresolved (different_timeframe scope)
- Add 'european equivalent' to differentiation related keywords so observation-5 evidence directly shares the differentiation concept with the condition (direct_match scope)
Updates:
- decision-condition-status tests to use present-state condition text where needed, and correct expectations for the two actual fixture cases
- Evidence-condition-scope tests for both actual fixture examples
- Design evolution log with Experiment 25B findings confirming long-investigation statuses
Move EVIDENCE_DIRECTION_GROUPS out of the mock fixture library into
lib/graph/evidence-direction.js where it belongs. Remove unused
DECISION_CONDITIONS and CONTRADICTION_KEYWORDS exports from scenarios.
Add Experiment 24A entry to the design log.
