Adds the CI gate that runs on every PR touching templates/, the catalog
validator, or its tests. The Action:
- runs tools/test_build_catalog.py (catches drift between validator +
its own test suite on the same PR that introduces the drift)
- runs tools/build-catalog.py --check (validates every shipped .scarftemplate
against the same invariants ProjectTemplateService.verifyClaims enforces
at install time)
- posts a PR comment with the last 3 KB of the validator log on failure,
so contributors see the specific mismatch without hunting through the
Actions UI
.github/PULL_REQUEST_TEMPLATE/template-submission.md is the author-facing
checklist that mirrors templates/CONTRIBUTING.md. Opt-in via the
?template=template-submission.md compare URL (documented in the
contribution guide). CONTRIBUTING.md now links both the PR template and
the workflow file so authors know what to expect.
Phase 4 closes the community loop — from this commit on, a stranger can
fork the repo, follow templates/CONTRIBUTING.md, push a PR, and get
deterministic green/red feedback before a maintainer ever looks at it.
