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 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
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
