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 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
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.
Implement the three-dimensional assessment (phase, progress, conversation
health) that sits between narrative and behaviour selection.
Key changes:
- lib/assessment/investigation-state-assessor.js: assessor module with
countObservations, assessPhase, assessProgress, assessConversationHealth,
assessInvestigationState — deterministic classifiers using known rules
- tests/investigation-state-assessor.test.js: 51 tests covering phase
classification (orienting→concluding), progress thresholds, health
conditions, confidence aggregation, edge cases, and observation counting
- lib/graph/orchestrator.js: integration calls passing correctly-shaped input
to assessInvestigationState() at three call sites (~552, ~904, ~1013)
Design decisions encoded in this iteration:
- countObservations counts nodes with known/resolved status + high-confidence
non-unknown non-state nodes (not just explicit observation-kind nodes)
- Phase uses seven values including cannot_determine for insufficient data
- Progress uses resolution ratio thresholds: accelerating (>0.6), steady
(0.2-0.6), stalled (<0.2 with ≥1 resolved)
- Overall confidence = minimum across all three dimensions (conservative)
Also adds investigation-state-assessment-contract.md and updates
design-evolution-log, investigation-state-assessment.md (status header),
and investigation-turn-cycle.md (implementation status table).
