What changed

Adds the first, manual-only half of the live Ghost content smoke. The workflow reads posts and pages from main.ghost.is, reduces each response to privacy-safe structural signatures, and writes aggregate counts to the job summary.

The authenticated job runs only for TryGhost/algolia on main. It has read-only permissions, keeps the Content API key on the execution step, rejects redirects and malformed pagination, and never writes a baseline, fixture, artifact, cache, or issue.

The first authenticated read still happens after this merges. A second maintainer can then review the aggregate-only summary before #219 records a baseline and adds the schedule.

Verification

  • pnpm test (151 tests)
  • pnpm test:coverage (95.05% statements, 91.83% branches)
  • pnpm typecheck
  • pnpm lint
  • actionlint .github/workflows/live-ghost-content-smoke.yml
  • package dry run contains no smoke source or tests

Closes #218

Added a privacy-bounded structural census runner and manual-only upstream workflow for `main.ghost.is`. The runner validates the target, transport, Content API pagination, extractor invariants, and canonical aggregate signatures while sanitizing every report; deterministic tests cover the workflow trust boundary and offline failure paths.

Walkthrough

This change adds a typed live Ghost content smoke test for posts and pages. It validates API responses, pagination, HTML structure, extractor invariants, deterministic signatures, and optional baseline drift. It adds a CLI, package script, coverage and TypeScript configuration, and a manual-only GitHub Actions workflow. Vitest tests cover successful runs, failures, sanitization, drift, and workflow restrictions.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to be8e5

The new smoke report can mark a run successful while content signatures are missing or counts have changed, masking structural drift. The PR is not merge-ready until the status classification and regression coverage are corrected.

171-171: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Sort the counts numerically.

Array.prototype.sort without a comparator sorts by string value. [1, 2] passes today. A future fixture that produces counts such as 2 and 10 would sort to [10, 2] and fail for the wrong reason. Pass a numeric comparator, or use expect.arrayContaining.

♻️ Proposed comparator
-        expect(report.signatures.map(signature => signature.count).sort()).toEqual([1, 2]);
+        expect(report.signatures.map(signature => signature.count).sort((a, b) => a - b)).toEqual([

Add a case for an empty collection.

The pagination cases all use pages: 2. No case covers the real Ghost empty-collection response, where meta.pagination.pages is 0 and total is 0. That shape currently fails isPositiveInteger(pages) in readPagination. Add the case, so the intended behavior for a site with no published pages is pinned by a test.

Consider covering smoke/cli.mts as well.

The coverage include list adds live-ghost-content-smoke.mts but omits smoke/cli.mts. cli.mts holds the transport, the URL construction, the environment wiring, and the exit-code handling. None of that is exercised by the two new test files. Add it to include once tests exist, so the transport contract stays verified.

512-529: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low value

Consider making the determinism double-parse optional.

observeHtml calls normalizeStructure twice, and validateExtractionFragments parses the same HTML a third time. Each item therefore incurs three parse5 parses. On a large census this triples the dominant cost. The determinism check is valuable, so consider running it on a sample of items rather than every item.

Keep the extractor and census allowlists separate.

Use EXTRACTOR_SOURCE_TAGS for allowedSourceTags, and keep SELECTED_TAGS for selectedCounts. Keep allowedHeadingRanks aligned with HeadingRank to prevent stale validation when extractor domains change.

Bound live reads with a 30-second abort timeout and configure the smoke job for
15 minutes. In the workflow test helpers topLevelBlock and stepContaining, parse
YAML before policy assertions, using local structure checks while treating
referenced reusable or composite actions as a separate coverage boundary.

Bound live requests and the manual workflow so an upstream stall cannot occupy a runner indefinitely. Preserve the original smoke classification when job-summary reporting also fails, and tighten the workflow action allowlist.

638-639: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Classify every baseline difference as structural drift.

Line 639 checks only drift.added. A missing baseline signature or a changed signature count returns ok even though the report contains drift. Return structural-drift unless all three drift lists are empty. Add regression cases for missing signatures and changed counts.

-    const category = drift.added.length === 0 ? 'ok' : 'structural-drift';

Restricted structural signatures to reviewed Ghost class tokens so authored kg-prefixed values cannot affect the census. Added deterministic subprocess coverage for the real CLI adapter and documented the maintainer-only workflow command.
