Phase 1 verdict: COHERENT_HOME with one BLOCKING flag. The slash command can land entirely inside existing canonical surfaces (next-chapter-os Next.js app for the API route, Mac mini Hermes worker for the long-running pipeline, Supabase for queue and storage). No new repo, no new DB, no new domain required. The blocking flag: confirm Slack workspace signing secret exists before any code is written.
Architect cannot test whether Vercel function timeouts (60 to 300 seconds) actually accommodate the 4-minute pipeline. Stipulated: must run async behind a queue, not inside the Vercel handler. If the user assumed sync execution when they said "just run", that gap surfaces here.
Pattern observed: every "make it Slack-callable" feature defaults to "stand up a new webhook receiver / new repo." This is the third time the canonical answer has been "use the existing next-chapter-os Next.js app's /api/* surface." Recommend codifying as a sprawl-prevention rule in architect's SKILL.md.
Slack-callable buyside hunt fits cleanly into existing infra. The only blocker is whether Slack app credentials exist. Everything else is plumbing.
