Experiment 47: created a test-only diagnostic helper that inspects existing
graph relationship fields (dependsOn, affects, parentId, childIds on nodes;
fromNodeId/toNodeId + relationship on edges) to distinguish coherent
investigations (multiple unknowns sharing one anchor) from scattered ones.
Three controlled fixtures confirm the helper works: shared_anchor vs
separate_anchors vs insufficient_data — all with identical structural counts
(6 nodes, 4 active unknowns). All three produce identical too_broad output
from the existing assessor, confirming no production code changes needed.
Existing-scenario inspection (3 real scenarios from Exp 39-46) all return
insufficient_data — current data lacks populated relationship fields on
unknown nodes. This means the gap is not purely in assessment logic but also
in upstream data quality.
Closed Experiment 46. Updated design-evolution-log and handoff.
Experiment 45 — passive boundary experiment measuring the existing
assessor's too_broad threshold from two to five competing unknowns.
Key findings:
- Boundary switches exactly between three and four active unknowns
- Clarify eligibility follows the same boundary
- Resolved-item gate works correctly (1 stays too_broad, 2 clears it)
- 2–3 unknowns return cannot_determine health (not healthy or too_broad)
- Boundary appears mechanically clear but conceptually uncertain
No production code changed. Synthetic fixtures only.
Passive diagnostic: zero Clarify-eligible turns across 10 real-scenario
assessments. Two findings — (1) orienting-based rule is dead code because
assessor never produces phase=orienting, (2) too_broad trigger validly narrow
but untested by any fixture. Created focused test file with 31 assertions.
All regression tests pass: 51 behaviour-selection + 33 reachability + 51
assessor = 166 total.
Experiment 41 compared two passive alternatives for reducing Acknowledge dominance:
Variant A (priority reordering): evaluate Summarise/Pause before Acknowledge
- Converges on concluding→summarise and stalled→pause correctly
- Introduces false-positive summarise at long-investigation t3
Variant B (Acknowledge exclusions): gate Acknowledge via phase/progress/health
- Converges on the same two genuine changes without false-positives
- Recommended: cleaner boundaries, preserves Acknowledge for healthy focus states
Both variants produce identical results for 2 of 7 tested turns.
Variant A diverges at long-investigation t3 (focusing phase with resolvedNodeCount=3).
Variant B correctly preserves Acknowledge there via its exclusion list.
Test files:
- tests/behaviour-selection.counterfactual.test.js (44 tests, new)
No production code changed.
