+# Archive Summary — 2026-02-10
+
+**Biggest single day of Hydrotech Beam work.** Full details archived from daily log at 30-day threshold.
+
+## Key Events
+- Received 3 KBS capture sessions from Antoine (NX/Simcenter walkthrough of Hydrotech Beam model)
+- Tech Lead processed sessions → KB Gen 002 update (commit `b88657b`)
+- Mass corrected to **1,133.01 kg** (`p173`) — Antoine correction, ground truth
+- Binary introspection of Beam.prt → full expression table extracted (commit `15a457d`)
+- DV baselines confirmed NOT round: face_thickness=21.504, core_thickness=25.162
+- `beam_lenght` has TYPO in NX (no 'h') — must use exact spelling
+- Gaps G12-G14 closed
+
+## Optimization Pipeline Built (Full Chain)
+1. Optimizer updated strategy with corrected baselines (commit `3e51804`)
+2. Auditor reviewed → APPROVED WITH CONDITIONS (hole spacing formula + web height constraint fixed, commit `94bff37`)
+3. Study Builder completed Phase 1 code: run_doe.py, sampling.py, geometric_checks.py, nx_interface.py (commit `017b90f`)
+4. Study Builder delivered NXOpenSolver wrapper around existing Atomizer engine (commit `33180d6`)
+5. Tech Lead refined NXOpenSolver v2 with auto-detection + fallbacks (commit `390ffed`)
+6. Antoine tested on dalidou → 2 bugs fixed (commit `135698d`)
+7. Full refactor of nx_interface.py → AtomizerNXSolver (commit `126f0bb`)
+
+## Key Technical Facts (Preserved)
+- Beam: 5,000mm length, cantilever (left fixed, right 10,000 kgf down)
+- Hole span = 4,000mm (`p6`), kept fixed (Manager decision)
+- Material: ANSI Steel 1005 (future: aluminum 6061, stainless ANSI 310)
+- Mesh: CQUAD4 thin shells, mid-surface idealization, element size 67.4/2
+- Conda env: `atomizer` on Windows (dalidou), all deps pre-installed
+- Windows path: `C:\Users\antoi\Atomizer\projects\hydrotech-beam\`
+- Existing engine reused: NXSolver + NXParameterUpdater + pyNastran extractors
+
+## Infra Fixes
+- Study Builder model corrected (`claude-sonnet-5` → `claude-sonnet-4-20250514`)
+- API auth propagated to all agents from Manager's auth-profiles.json
+
+## CEO Requests Logged
+- NX Simcenter 3D MCP server — Phase 2/3 roadmap item
+
+## Open at EOD
+- Antoine to test `--backend nxopen` smoke test on dalidou
+- Full 51-trial Phase 1 run pending
+- Phase 2 TPE optimization pending
