Experiment 60B.61 — Decision Remaining-Material-Factor Detection

Status: PASSED

Objective

Answer: Does the dedicated remaining-material-factor helper work correctly once malformed tests are repaired, without any broader applyValidatedProposal integration?

Answer: YES.

Scope (bounded)

Helper detection experiment only. No closure integration.

Production code added (2 helpers + internal support)

Export	Role
`hasRemainingMaterialFactors(decisionNodeId, graph)`	Public boolean — `true` if any unresolved unknown remains material to the decision
`countRemainingMaterialFactors(decisionNodeId, graph)`	Count variant — used internally by `hasRemainingMaterialFactors`; kept as exported for potential future use

Set-based deduplication of factor IDs across routes (no double-count)
Decision self-count excluded (node.id === decisionNodeId)
Terminal statuses excluded: known, resolved, contradicted
Helper-only. No integration into applyValidatedProposal return, no closure logic change.

Supported Routes

Route	Relationship Path
A — hierarchy	`parentId` chain or `childIds` membership
B — direct dependency	`depends_on` edge to decision
C — consequence	unknown → `{affects,may_cause,causes}` → option → `contained_in` → decision
D — containment	unknown → `contained_in` → option → `contained_in` → decision

Excluded (returns false)

Known / resolved / contraduted statuses
supports / measures weak links
Arbitrary non-approved connectivity (other)
The decision node itself
Non-unknown kind nodes (e.g., observations)

Test Suite (14 cases in 60B.61 block)

Containment-only unresolved factor → true
Same factor resolved → false
may_cause option-linked factor → true
Valid direct depends_on factor → true; resolved → false
Hierarchy child factor → true
Supports / measures weak link → false
Decision node alone does not self-count → false
Another genuine unresolved hierarchy child remains → true
Status = known excluded → false
Status = contradicted excluded → false
Non-unknown kinds excluded → false
60B.56 sufficiency (all factors resolved) → false
Arbitrary connectivity via other edge → false
Additional resolution state within Route B test → false

feat(reasoning): detect remaining decision factors
docs: record decision factor detection

WHAT IS NOW GUARANTEED

The helper hasRemainingMaterialFactors(decisionNodeId, graph) correctly identifies unresolved material factors for a decision node across all four approved routes (A–D), with Set-based deduplication and proper terminal-status exclusion. No production behaviour outside the helper itself was changed.

WHAT REMAINS OPEN

Decision-sufficiency closure integration remains a separate next experiment. The helper detects but does not influence any decision-closure logic at this time.
