Calendar overlay approved. Active deal touchpoints (HR.com, Design Precast, Ches Booker) gated against high-risk windows. Stage 4 deferred until Tuesday morning if it had been needed.
Cross-referenced active deal calendar (HR.com weekly check-ins, Design Precast EBITDA review) against proposed cutover stages. Marked Stage 3 (API ports + Lob) and Stage 4 (Supabase repoint) as 'daytime + co-pilot only'.
Architect's plan was correct in shape but timing-silent — adding a 'when' column converted shape-correct to operationally safe.

Stage 1 verification was the right tonight-only scope. Stages 2-6 wait for fresh-headed daytime sessions with Mark on standby.
Will gate every infra task against active-deal calendar before greenlighting execution.
