 ### Solver Pipeline Status
 - ✅ NX journal solve working (DesigncenterNX 2512)
-- ✅ Mass extraction via `p173` expression
+- ✅ Mass extraction fixed — commit `580ed65` (MeasureManager after geometry rebuild, no more stale p173)
 - ✅ Displacement & stress extraction via pyNastran OP2 parsing
 - ✅ Iteration archival (params, results, OP2, F06)
 - ✅ History DB (SQLite + CSV, append-only, survives --clean)
 - ✅ Geometric pre-checks (hole overlap, web clearance)
-- 🔄 Full 51-trial DOE run pending
+- ✅ Displacement constraint relaxed: 10mm → 20mm (DEC-HB-012)
+- 🔄 Pull fix on dalidou → test single trial → re-run full DOE
+
+### DOE Phase 1 Results (pre-fix, 51 trials)
+- 39/51 solved, 12 geo-infeasible (hole overlap)
+- **0 fully feasible** at 10mm constraint (min displacement ~19.6mm)
+- **Mass = NaN on all trials** — extraction bug (now fixed)
+- Stress constraint met by several trials
+- With 20mm relaxation, many trials should now be feasible
 
 ### Development Workflow
 - **Git only** for development (git push/pull between server and dalidou)
