  • impact
    getmyagentnow.com/demo showed "no recent agent activity" for ~4 hours while Supabase held 79 valid events in the demo tenant. Portfolio link shared in a job application during the window.
    root cause
    Supabase PostgREST was caching query results at its edge. The Vercel function made identical queries (same table, same tenant filter, same ORDER BY / LIMIT). PostgREST served stale empty rows even after new events landed. Local dev hit a fresh connection per restart and never reproduced.
    resolution
    Added Cache-Control: no-cache header on a demo-scoped Supabase client. Kept the shared getSupabaseAdmin() singleton cache-enabled for cockpit and policy routes. Also removed an overly-aggressive AbortSignal(3s) that was silently returning empty on Vercel cold starts.
    prevention
    Centralized isDemoEligible predicate so aggregate stats query and session list filtering always agree on what counts as a real event.
