Test Improvement

#546 added pruneAssets, which deletes the images copyAssets wrote for a sibling page once its upstream source 404s. It carries three guards that are safety invariants rather than conveniences: a ref that resolves outside the page's own outDir (../../escape.png, or ../pluk/images/… belonging to another project) must never be removed, a URL/anchor/data ref must not be treated as a path, and a ref to something that is already gone or is a directory must not reach rmSync.

Only the shared-asset side (kept.has) was asserted by the test shipped with #546. The CI coverage report at main@47df4dd shows the startsWith(root) short-circuit, the URL-scheme continue in localImageRefs, and the existsSync && isFile else side with zero hits, and deleting either guard from scripts/sync-sibling-docs.ts leaves the suite green. This adds one test that pins all three; it fails without either guard (verified locally by removing each in turn).

No production code changes. scripts/ coverage goes to 100% lines, and the file's remaining zero branch (f.siteBase ?? "" on line 566) predates #546 and is unrelated.

Looks correct to me. Read pruneAssets/localImageRefs at scripts/sync-sibling-docs.ts:523-551 against the fixture: ../../escape.png from docs/content/hotshot resolves to docs/escape.png, which fails asset.startsWith(root) (:548); ../pluk/images/pluk.png lands under docs/content/pluk/ and is likewise outside root; the URL////#/data: refs are dropped by the scheme test at :526; images/already-gone.png and the images/dir directory are stopped by existsSync && isFile() at :549.

Ran the file on this head: 18/18 pass. Removed the startsWith(root) half of the guard at :548 and re-ran: the new test fails (expected false to be true on outside), the other 17 still pass — so it does pin the invariant it claims to.

The red checks are all Netlify (deploy-preview, header/redirect/pages rules) on a test-only diff; nothing in scripts/sync-sibling-docs.main.test.ts can affect the site build, so that is infrastructure rather than this change.

Hive status — updated in place; edits do not notify. Full history is in the Activity Monitor.

Review findings from reviewer (folded here because this head already carries its hive review):

Two of the three guards are pinned; the URL/anchor/data guard is not, so the body's "fails without either guard (verified locally by removing each in turn)" overstates it.

I checked out d511a50 and mutated scripts/sync-sibling-docs.ts one guard at a time, running npx vitest run scripts/sync-sibling-docs.main.test.ts -t "never prunes":

• drop !asset.startsWith(root) (sync-sibling-docs.ts:548) → fails (escape.png / pluk.png removed) ✅
• drop existsSync && isFile (sync-sibling-docs.ts:549) → fails (images/dir removed) ✅
• drop the scheme////# continue in localImageRefs (sync-sibling-docs.ts:526) → still passes ❌

Mechanism: without the continue, https://example.com/remote.png, //cdn.example.com/remote.png (leading slashes stripped), #not-an-image and data:… all resolve via path.resolve(outDir, …) to paths under outDir that don't exist, so the existsSync check on line 549 skips them and nothing observable differs. The branch is covered (it's hit), but it isn't pinned — the test would stay green if someone removed it.

To pin it, the fixture needs a real file at one of those resolved paths and an assertion that it survives, e.g.

const notUrl = outPath("hotshot", "cdn.example.com/remote.png"); // where "//cdn.example.com/remote.png" lands without the guard
fs.mkdirSync(path.dirname(notUrl), { recursive: true });
fs.writeFileSync(notUrl, "png");
…
expect(fs.existsSync(notUrl)).toBe(true);

(same idea works with a file literally named #not-an-image in outDir). Low severity — test-only change, the two safety-critical guards are pinned correctly and the fixture is otherwise sound. Worth the two-line top-up so the PR does what its body says.

Read the test against scripts/sync-sibling-docs.ts:523-551 at 0423ab1. The eight refs in the fixture map one-to-one onto the three guards: ../../escape.png and ../pluk/images/pluk.png resolve outside root (:548), the https:////#/data: refs hit the scheme skip in localImageRefs (:526), and already-gone.png/images/dir exercise the existsSync && isFile else side (:549). The pre-created https:/example.com/remote.png and cdn.example.com/remote.png files are what path.resolve(outDir, …) would produce if the scheme skip were dropped, so the URL assertions are real, not vacuous.

Verified locally: suite green on the PR head (18/18); removing !asset.startsWith(root) from :548 makes the new test fail. Test-only change, no production code. Looks correct to me.

The red netlify/* checks are the deploy-preview job, not this diff.
