-## Hydrotech Beam — KBS Sessions Received
-- Antoine recorded 3 KBS capture sessions on his Windows machine (NX/Simcenter)
-- Data location: `/home/papa/ATODrive/Projects/hydrotech-beam/Hydrotech-Beam/_capture/`
-- Sessions: `20260210-132817` (6s), `20260210-161401` (38s), `20260210-163801` (414s main session)
-- Main session is a full walkthrough of the NX model with parameter names, values, BCs, materials
-
-### New Information from KBS Sessions
-- Beam length = 5,000 mm (`beam_length` expression)
-- Cantilever: left fixed, right loaded with 10,000 kgf downward
-- Hole span = 4,000 mm (`p6`), holes start/end 500mm from beam ends
-- Mass via expression `p1` (NOT `p173` as we had) — starting 11.33 kg (CONTRADICTS 974 kg baseline!)
-- Material: ANSI Steel 1005 — future: aluminum 6061, stainless ANSI 310
-- Mesh: CQUAD4 thin shells, mid-surface idealization, element size = 67.4/2
-- New expression names: `beam_half_height`, `beam_half_width`
-- `p6` (hole span) as potential new design variable
-- 4 screenshot triggers in the session metadata
-
-### Actions Taken
-- Posted acknowledgment + next steps in #project-hydrotech-beam
-- Spawned Tech Lead sub-agent (label: tech-lead-kb-update) to:
-  - Process all 3 transcripts
-  - Update KB to Gen 002
-  - Reconcile mass discrepancy (11.33 kg vs 974 kg)
-  - Close resolved gaps (G1, G2, G5 partial, G8)
-  - Update CONTEXT.md
-  - Commit to Gitea
-
-### Workflow Status
-- Step 1 (Optimizer strategy): OPTIMIZATION_STRATEGY.md exists as DRAFT from Feb 9
-- Current: Processing new KB data before proceeding
-- Next: Optimizer revises strategy with confirmed params → Auditor review → Study Builder code
-- Model files confirmed synced: Beam.prt, Beam_fem1.fem, Beam_fem1_i.prt, Beam_sim1.sim
-
-### Completed
-- [x] Tech Lead completed KB Gen 002 update — commit `b88657b`
-- [x] Mass corrected AGAIN: **1,133.01 kg** (`p173`), NOT 11.33 kg — Antoine corrected us
-- [x] Binary introspection of Beam.prt — extracted complete expression table (commit `15a457d`)
-- [x] DV baselines are NOT round: face_thickness=21.504, core_thickness=25.162 (not 20/20)
-- [x] Gaps G12-G14 closed (beam_half_height=250, beam_half_width=150, holes_diameter expression confirmed)
-- [x] Important: `beam_lenght` has TYPO in NX (no 'h') — scripts must use exact spelling
-- [x] `hole_count` links to `Pattern_p7` in the NX pattern feature
-- [x] CONTEXT.md updated with full expression map, pushed to Gitea
-
-### Pending — Waiting on Antoine
-- [ ] Baseline re-run (G10, G11) — need current displacement and stress values
-- [x] Decision on `p6` (hole span) — kept fixed at 4,000mm for now (Manager decision)
-
-### Windows Environment (dalidou)
-- Path: `C:\Users\antoi\Atomizer\projects\hydrotech-beam\` (Syncthing from server)
-- Python: `anaconda3\envs\atomizer` (conda env named "atomizer")
-- Antoine ran smoke test on Feb 11 — hit 2 bugs, both fixed (commit `135698d`)
-- NXOpen implementation still needed (solve, extract_displacement, extract_stress)
-
-### In Progress
-- [x] Optimization strategy updated with corrected baselines (commit `3e51804`)
-- [x] Auditor review: APPROVED WITH CONDITIONS — 2 blockers found and fixed:
-  - Hole spacing formula: `span/(n-1)` not `span/(n+1)` — fixed
-  - Web height constraint: added `500 - 2*face - dia > 0` pre-check — fixed
-  - Commit `94bff37`
-- [x] Study Builder completed Phase 1 code (commit `017b90f`) — verified end-to-end with stub solver
-  - 6 files: run_doe.py, sampling.py, geometric_checks.py, nx_interface.py, requirements.txt, README.md
-  - Pre-flight geometric filter catches ~24% of infeasible combos
-  - NXOpen template ready — needs 3 methods filled in on Windows (solve, extract_disp, extract_stress)
-- [ ] Antoine running baseline SOL 101 for displacement + stress (parallel)
-- [ ] `p6` kept fixed at 4,000mm for now (DEC by Manager)
-
-### NXOpenSolver → Existing Engine Integration (Late Evening)
-- Antoine confirmed: runs everything from his "Honda atomizer" conda env on Windows
-- Uses existing `run_optimization.py` which calls `NXSolver` + `NXParameterUpdater` + pyNastran extractors
-- **Key insight:** We do NOT need to write NXOpen code from scratch — the Atomizer engine already has everything:
-  - `optimization_engine/nx/solver.py` — journal-based solver via `run_journal.exe`
-  - `optimization_engine/nx/updater.py` — expression updates via `.exp` import
-  - `optimization_engine/extractors/extract_displacement.py` — pyNastran OP2
-  - `optimization_engine/extractors/extract_von_mises_stress.py` — pyNastran OP2, kPa→MPa
-  - `optimization_engine/extractors/extract_mass_from_expression.py` — from temp file
-- Delegated to Study Builder (label: `study-builder-nx-impl`) to rewrite `NXOpenSolver` as a wrapper around existing engine
-- Asked Antoine to confirm `pyNastran` is installed in the conda env
-
-### Infra Fixes
-- Study Builder model was set to non-existent `claude-sonnet-5` → fixed to `claude-sonnet-4-20250514`
-- All agents were missing Anthropic API auth → propagated from Manager's auth-profiles.json
-- Agents fixed: secretary, study-builder, optimizer, auditor, technical-lead
-
-### Study Builder Delivered — NXOpenSolver (commit `33180d6`)
-- Wraps existing Atomizer engine: NXParameterUpdater, NXSolver, pyNastran extractors
-- HEEDS-style iteration folders, 600s timeout, CQUAD4 shell stress, kPa→MPa
-- Full interface compatibility with run_doe.py preserved
-- 252 additions, 126 deletions
-
-### Tech Lead Refined — NXOpenSolver v2 (commit `390ffed`)
-- Built on Study Builder's work with improvements:
-  - Element type auto-detection (tries solids first, falls back to CQUAD4)
-  - OP2 fallback path (solver result → expected naming convention)
-  - Mass fallback via `_temp_part_properties.json`
-  - Follows SAT3_Trajectory_V7 FEARunner pattern exactly
-- Both commits stack cleanly on main, latest is the active version
-
-### Late Night — Antoine Follow-Up (~23:00-01:00 UTC)
-- Antoine returned: "Yeah! What's next?" — confirmed ready to move forward
-- Asked about conda env: confirmed he uses `conda atomizer` (defined in `environment.yml` at repo root)
-  - Includes optuna, scipy, numpy, pandas, pyNastran — all Phase 1 deps covered
-- Asked "What's the NXOpen implementation about?" — explained the 3 bridge methods (solve, extract_disp, extract_stress)
-- Antoine asked how this relates to legacy Atomizer studies (SAT3, mirror blank)
-  - Confirmed: same engine (NXSolver, NXParameterUpdater, pyNastran extractors)
-  - Differences: geometric pre-filter, LHS sampling, cleaner separation, project-scoped
-- **Antoine approved:** "go ahead and do it"
-- Delegated NXOpen implementation completion to Technical Lead (label: `hydrotech-nxopen-impl`)
-  - Task: complete NXOpenSolver.evaluate() using existing Atomizer engine components
-  - Reference: SAT3_Trajectory_V7, bracket study, existing engine classes
-
-### Feb 11 Morning — Bug Fixes + Final Refactor
-- Antoine tested on dalidou, hit 2 bugs:
-  1. SQLite duplicate study name → fixed with `load_if_exists=True` + `--clean` flag
-  2. Sampling crash with `n-samples 1` → skip stratified patching when n < 11
-  - Commit `135698d`
-- **Full refactor of nx_interface.py** (commit `126f0bb`):
-  - `AtomizerNXSolver` wraps existing `optimization_engine` (NXSolver + pyNastran extractors)
-  - HEEDS-style iteration folders, .exp file generation, OP2 extraction
-  - StubSolver improved with beam-theory approximations
-  - Windows path confirmed: `C:\Users\antoi\Atomizer\projects\hydrotech-beam\`
-  - Conda env: `atomizer` (all deps pre-installed)
-
-### Future Initiative — NX Simcenter 3D MCP (CEO request, Feb 11)
-- MCP server on dalidou for direct NXOpen interaction
-- Endpoints: expressions.list/get/set, model.update, solve.run, results.*, introspect, screenshots
-- Eliminates pyNastran, temp files, journal generation — all via NXOpen API
-- Target: Phase 2/3 roadmap
-- Logged per Antoine's explicit request — not blocking current work
-
-### Next
-- [ ] Antoine tests `--backend nxopen` on dalidou (single trial smoke test)
-- [ ] Full 51-trial Phase 1 run
-- [ ] Phase 2 TPE optimization

+## Nightly Digestion — OP_11 (Incremental)
+
+### STORE
+- No new activity. Zero file changes across all workspaces since Mar 7. Day 19 of idle.
+
+### DISCARD
+- **Archived Feb 10 daily log** (30 days old) → `memory/archive/2026-02-10.md`
+  - Biggest single day of Hydrotech Beam work. Archive summary preserves all key facts, commits, technical specs, and open items.
+  - Original removed from active memory directory.
+- Feb 11 log reaches 30-day threshold tomorrow (Mar 13) — queued for next cycle.
+- Mar 1–11 daily logs continue to contain only digestion-cycle entries (no substantive activity). Will compress when they hit 30 days.
+- No contradictions found.
+
+### SORT
+- Nothing to promote or reorganize. All key Feb 10 findings were already stored in MEMORY.md and project KB during the active phase.
+
+### REPAIR
+- All key paths verified: taskboard.json, mc-update.sh, mission-control tasks, QUICK_REF.md, CLUSTER.md, taskboard skill, orchestrate skill, AGENTS_REGISTRY.json, mission-control-protocol.md — **all OK**.
+- No agent workspace changes since Mar 7.
+- No broken references found.
+
+### EVOLVE
+- **Standing amendment proposal (20th consecutive near-identical nightly cycle):**
+  OP_11 §Triggers idle-mode rule: when no workspace file changes for >7 consecutive days, switch nightly digestion to **weekly-only**. Resume nightly when activity resumes. This cycle archived 1 log — the only substantive action in 20 nightly runs. Weekly would have caught this on the same schedule.
+  - **Requires CEO approval** per protocol change rules.
+
+### SELF-DOCUMENT
+- No doc changes needed. All docs reflect current state.
