`api.cdnjs.com` fronts the cdnjs library catalog, no key.

## Probe 1 — direct library lookup
`GET https://api.cdnjs.com/libraries/font-awesome` → 200, `{"name":"font-awesome","latest":"https://cdnjs.cloudflare.com/ajax/libs/font-awesome/7.3.1/css/all.min.css","sri":"sha512-...","version":"7.3.1",
"filename":"css/all.min.css","homepage":...,"license":...,"repository":{...}}` — the `latest` field is a
ready-to-use full URL, `sri` the matching Subresource Integrity hash for it, both in one call.

## Probe 2 — unknown library
`GET /libraries/this-lib-zzz-notreal9000` → **404**, `{"error":true,"status":404,"message":"Library not
found"}`, `x-release` header carries a git commit SHA of the catalog build serving the answer.

## Probe 3 — `?search=` can return results unrelated to the query for a library that is not on cdnjs
`GET /libraries?search=lucide` (lucide-icons, the icon package probed elsewhere in this batch, is not a
cdnjs-hosted library — confirmed by probe 4) → **200**, `{"results":[{"name":"paradeiser", "description":
"Paradeiser is an easy to use menu for mobile views"},{"name":"beepjs","description":"Makes browser
beep."}],"total":2,"available":2}` — two hits, repeated identically across three separate calls, neither
one's name, description, or (visible) keywords contains "lucide" or anything obviously related to icons or
design. A caller using this search to answer "does cdnjs carry X" gets a non-empty, confident-looking
result for a library that isn't there, rather than an empty list.

## Probe 4 — confirms probe 3: a direct lookup for the same name is a clean 404
`GET /libraries/lucide` → 404 (same shape as probe 2) — so the library genuinely isn't on cdnjs; the
`search=lucide` hits in probe 3 are not a partial/fuzzy match surfacing a differently-named real package,
they are simply wrong for this query. `?search=lucide-static` (the exact npm/CDN package name used
elsewhere in this batch) correctly returns `{"results":[],"total":0,"available":0}` — so the odd behavior
is query-specific, not a universal search bug.

How observed: 2026-10-05, 06:08-06:09 UTC, curl 8, repeated 3x for reproducibility.
