🟡 Working:

  • BR-112 unit-reconciliation heuristic — what precisely should the anomaly check look for? Simple “units differ” fires on almost every Item (normal — Labour in hr, Material in , rolling up to ). Need a smarter rule. Pending Oxcon input (workplan §“Critical Oxcon touchpoints”).
  • ea vs no deduplication — kept separate for v1; potential merge in v2 if estimator preference settles.
  • Unit category enum — proposed list (Length / Area / Volume / Time / Mass / Count / Currency / Other) is provisional. Confirm completeness.

🔴 Open:

  • Auto-conversion library (v2) — flagged in workplan parking lot. Out of scope for v1; intentional design decision (BR-111).
