# Vercel variant: Vercel builds Preview deployments on every push and gates the
# PR via the Vercel GitHub integration check. Running `npm run build` here too
# would duplicate Vercel's work for ~3-5 minutes per PR with no added signal.
#
# What this CI covers (and Vercel does not):
#   - Lint (cheap belt-and-suspenders)
#   - Schema-map drift check (docs/SCHEMA_MAP.md updated when scripts/add-*.js changes)
#   - Migrations apply cleanly (node-pg-migrate against ephemeral Postgres 16)
#   - Unit tests (vitest)
#
# NOTE: tcg-vault is JavaScript (not TypeScript). No `npx tsc --noEmit` step.
# Re-enable a type-check job if migrating to TypeScript.

    # Skip CI entirely for doc-only PRs. The `slash-ci-minutes` convoy
    # (2026-06-04) added this filter because every grep / lint / vitest /
    # migrate job that fires on a pure-docs PR (e.g. `.convoys/` seeds +
    # briefs, AGENTS.md edits, `docs/`) costs GitHub Actions minutes for
    # zero signal. The full job set still runs on code-touching PRs.

  # -modal-shell-without-primitive / -deprecated-color-aliases /
  # -stale-strings); the `slash-ci-minutes` convoy (2026-06-04) merged
  # them into one job to amortize a single actions/checkout across all

  # ALL violations across all 6 checks are reported in a single run
