## Key Events
- **Nightly Digestion Cron LIVE** — Job `e157faf0`, 4:00 AM ET daily, isolated agentTurn (manager), announces to #all-atomizer-hq
- **Hydrotech Beam resumed** — Antoine approved Phase 2. DOE Phase 1 gate check failed: 39/51 solved, 0 fully feasible, mass=NaN on all trials
- **Mass NaN Fix committed** — `580ed65`. Root cause: `solve_simple_workflow()` tried reading mass via stale `p173` expression after part switching. Fix: extract mass right after geometry rebuild using `MeasureManager.NewMassProperties()`
- **DEC-HB-012** — Displacement constraint relaxed 10→20mm (CEO approved, dummy case)
- Sub-agent issues: Tech Lead hit 200K token limit (×2), NX Expert couldn't post to Slack (channel routing issue for spawned agents)
- **Lesson:** Sub-agents need leaner prompts; Slack channel routing broken for spawned sessions
