deploy-prod — clean-worktree deploy + Reelier smoke

Vercel's git integration does not reliably auto-deploy main (verified 2026-07-18), and deploying from the dirty local checkout is forbidden. This is the canonical sequence.

Steps

1. Get the merge sha: git fetch origin main and note the commit to deploy.
2. Clean worktree deploy (env vars are baked at build, so this also picks up flag changes):

   git worktree add "$env:TEMP\sf-main-deploy" <sha>
   Copy-Item .vercel "$env:TEMP\sf-main-deploy\.vercel" -Recurse -Force
   Set-Location "$env:TEMP\sf-main-deploy"; npx vercel deploy --prod
   

3. Verify: npx vercel inspect <deployment-url> → target production + status Ready.
4. Smoke with Reelier (default — NOT the smoke-runner agent):

   Set-Location C:\Users\maxim\CascadeProjects\reelier
   node dist/cli.js run skills/sf-post-deploy-smoke.skill.md
   

   Level-0 deterministic replay: ~1-3s, 0 LLM tokens, per-step receipts in .reelier/runs/. Exit 0 = deploy smoked. This replaces a ~35-60k-token smoke-runner agent dispatch.
5. Escalation only on divergence: if a step fails, do NOT immediately re-run — a failed sentinel usually means the page copy changed (update the skill's assert) or the deploy is genuinely broken (check npx vercel logs). Dispatch the smoke-runner agent ONLY when the reelier failure needs judgment (e.g. deciding whether copy drift is intentional).
6. If the deploy touched migrations: verify on Neon that the new table/column exists (information_schema) — the build runs db:migrate, but confirm, don't assume.
7. Clean up: git worktree remove "$env:TEMP\sf-main-deploy" --force; git worktree prune.

Why Reelier-first

Deterministic replay with assertions IS the smoke test: same checks every time, receipts written, zero spend. The agent is the escalation path, not the default — the same L0-first/escalate-on-divergence ladder the replay product itself uses. When the smoke skill's sentinels drift because marketing copy changed, updating the assert line in reelier/skills/sf-post-deploy-smoke.skill.md is the fix (and gets a changelog line).
