name: Core Build (no extensions)

# Split out of a single serial job that took 7m43s wall-clock: npm ci 24s, lint
# ratchet 1m29s, build 2m00s, unit tests 3m31s, ratchets ~10s. None of those
# stages needed the previous one's output, so they were serial only by
# accident. Running them as independent jobs (and sharding the 897-file unit
# suite four ways) puts the critical path on `build` at roughly 2m30s.
#
# The prologue each job needs is in .github/actions/setup-core.

# Six concurrent jobs per push makes stale runs far more expensive than they
# were when this was one job, and a superseded push has nothing worth finishing.

      - name: Lint ratchet (no new ESLint errors)
        # `npm run lint` was never wired into CI, so ~60 legacy errors
        # accumulated. This ratchet (sibling of check:guards) fails only when
        # a PR ADDS an error beyond scripts/checks/eslint-baseline.json; the
        # baseline ratchets down as legacy errors get fixed.

      - name: Typecheck ratchet (no new TypeScript errors)
        # `npm test` does not typecheck: vitest transpiles and discards types,
        # so a type error passes all 18 000 tests and only surfaces in the
        # build. That happened twice on 2026-08-27. This also covers __tests__
        # files, which the Next.js build never compiles, so it is not merely a
        # faster copy of the build job.
        #
        # Baselined per FILE in scripts/checks/typecheck-baseline.json (539
        # legacy errors across 83 files, all in test files) and ratchets down.
        # Per-file rather than per-error-code on purpose: a code-keyed budget
        # would let a real regression hide behind a legacy fix elsewhere.
        run: npm run check:types

      - name: Antipattern ratchet (no new MFA-bypassing routes / naive öre-rounding)
        # Fails only if a PR ADDS a route that hand-rolls supabase.auth.getUser()
        # instead of the MFA-enforcing guard, or a new Math.round(x*100)/100.
        # Baseline lives in scripts/checks/antipatterns-baseline.json and ratchets
        # down as the A1 (route auth) and D1 (rounding) migrations land.

      - name: Validate konteringspaket catalogue
        # The system booking templates are data files under packs/ rather than
        # rows frozen inside a migration. This gate is what makes that safe: it
        # checks the schema, that every BAS account actually exists in the 2026
        # chart, and that each pack BALANCES when applied through the real
        # applyTemplate(). PR #1321 shipped seeded reference data that
        # contradicted the engine; that class of bug is structurally valid and
        # only a semantic check catches it.

      - name: Validate community registry
        # registry/ is the public source of truth for gnubok.se/community/registry
        # and takes entries by PR from outside the team. The gate checks the
        # frontmatter the website build consumes, and rejects JSX/import/export
        # in entry bodies: the site renders bodies through MDX, which would
        # execute those at build time.
