feat: add Atomizer HQ multi-agent cluster infrastructure

- 8-agent OpenClaw cluster (Manager, Tech-Lead, Secretary, Auditor,
  Optimizer, Study-Builder, NX-Expert, Webster)
- Orchestration engine: orchestrate.py (sync delegation + handoffs)
- Workflow engine: YAML-defined multi-step pipelines
- Agent workspaces: SOUL.md, AGENTS.md, MEMORY.md per agent
- Shared skills: delegate, orchestrate, atomizer-protocols
- Capability registry (AGENTS_REGISTRY.json)
- Cluster management: cluster.sh, systemd template
- All secrets replaced with env var references

+## Projects Active
+
+### **Hydrotech Beam Structural Optimization**
+- **Channel:** #project-hydrotech-beam  
+- **Status:** Intake complete, technical breakdown done by Tech Lead
+- **Objective:** 
+  - Reduce mass (~974 kg baseline)
+  - Reduce tip displacement (~22mm → target <10mm)
+  - Keep stress <130 MPa
+- **Design variables (4):** core thickness, face thickness, hole diameter, hole count
+- **Solver:** NX Nastran (static structural)
+- **Project folder:** `/home/papa/atomizer/projects/hydrotech-beam/`
+
+### Key Technical Finding
+- **⚠️ Critical issue:** Baseline already violates displacement constraint (22mm > 10mm target)
+- **Risk:** Feasible region may be tight
+- **Blocker:** 9 gaps identified by Tech Lead that need Antoine's input before optimization can proceed
+
+### Next Steps
+1. **🔴 URGENT:** Gap resolution session with Antoine
+2. Model validation
+3. DoE (Design of Experiments)
+
+## Communication
+- Antoine asked for updates on Hydrotech project (21:41 UTC)
+- Manager provided full briefing (21:43+ UTC)
+- Antoine mentioned posting details in #project-hydrotech-beam channel
+
+## Notes
+- Antoine initially seemed surprised I didn't see #project-hydrotech-beam content
+- I don't have access to read that channel directly
+- All project coordination happening through Manager per protocols

+# Pending Items — Needs Antoine's Attention
+
+## Hydrotech Beam Project — Status
+- Technical gaps resolved, displacement constraint relaxed 10mm → 20mm (DEC-HB-012, CEO approved)
+- Mass NaN bug fixed (commit `580ed65`)
+- **Next:** Pull fix on dalidou, test single trial, re-run full DOE with 20mm constraint
+- **Updated:** 2026-02-14 (digestion cycle)
