chore: add real content that was sitting untracked

Surfaced by today's untracked-files audit. None of these are accidents —
multiple are referenced by name in CLAUDE.md and memory files but were
never added.

Categories:
- docs/PHASE_AUDIT_GUIDE.md (106 LOC) — Claude Code phase audit guidance

  remain in service post-sidecar-drop (commit ba928b1 explicitly kept them)

Sensitivity check: scenarios use synthetic company names ("Heritage Foods",
"Cornerstone Fabrication"); audit reports describe code findings only;
no PII or secrets surfaced.

+## 13:00 emergency — Welder x2
+
+To: staffing@riverlinelogistics—nashvilledowntownbuild-out.example  
+From: dispatch@lakehouse.example  
+Subject: Confirmed Welders  
+
+Hello River Logistics Team,
+
+We are pleased to confirm that we have filled both roles with Melissa K. Rivera and Rachel D. Lewis for the Welder position, starting at 13:00 PM. Due to a subcontractor drop-out, we need two additional Welders by 3pm. Please use the cloud rescue path if Nashville supply is exhausted; pivot to within-radius first (if any in 75mi), then budget-permitting out-of-area.
