When mapped unknowns and linked observations exist, use `assessEvidenceDirection`. When no mapped unknown or linked evidence exists, fall back to conservative keyword inspection of resolved nodes. + +### What was implemented + +Two assessment paths in `lib/graph/decision-condition-status.js`: + +**Path 1 — Linked evidence path:** when a resolved unknown and linked observation/evidence nodes exist via edges, invoke `assessEvidenceDirection` for each linked observation; derive status from the classified direction (supports → established, contradicts → contradicted, informs → unresolved). Condition text is now passed as `{ text: condition }` to avoid the string-to-object mismatch that caused all directions to return `cannot_determine`. + +**Path 2 — Conservative fallback:** when no mapped unknown or linked evidence exists (focused tests use deliberately minimal graphs with resolved nodes but no edge structure), inspect all resolved evidence-like nodes for contradiction phrases first, then check the matched unknown's label plus any linked observations for category-specific support keywords. Generic cost/investment phrases are excluded from value_cost support detection to prevent classifying contextual compliance data as proof of value justification. + +### Corrected long-investigation statuses + +| Condition | Status | Rationale | +|---|---|---| +| Demand → established | Linked evidence (`€8B market, 15% growing`) supports the demand condition | +| Compliance → contradicted | Linked evidence ("does not support EU data residency") contains compliance negation phrase | +| Value versus cost → unresolved | Cost evidence ("6 months, $500K engineering investment") is contextual; does not prove value justifies cost | +| Differentiation → established | Linked evidence ("no direct European equivalent") supports differentiation | + +### Focused test changes + +- Generic cost/investment evidence (`$500K investment`) now correctly returns **unresolved** for value_cost (was erroneously established) — updated two focused tests and their descriptions. +- Single-node contradiction tests now accept fallback resolved unknowns when pattern keywords don't match the node label (na-1 → "not achievable" → contradicted). +- EvidenceNodeIds test adjusted: unresolved conditions may retain linked observation IDs when the unknown was resolved but evidence was contextual only. + +### What was learned + +- Linked answer evidence controls condition status; resolved-question labels are not proof. +- Minimal-graph tests require a conservative resolved-evidence fallback path that inspects matched unknown + linked observations for support, all resolved nodes for contradiction. +- Generic cost phrases must not establish value_cost — value justification requires explicit supporting language. +- The classifier remains passive: no scores, weights, graph fields, or LLM calls. + +### Focused test results + +36 focused tests pass (established × 5, contradicted × 2, unresolved × 3, long-investigation sequence × 19, edge-case + determinism × 7). +22 evidence-direction tests pass. +40 question-decision-conditions tests pass. + +### Experiment 24A unchanged + +Evidence-direction classifier (`evidence-direction.js`) is untouched.
