+The second one had been invisible since the beginning: `judgeHref()` skipped every href carrying a

  * unscanned. Same one-row price, same caveat — measure the surface first, pay
  * its backlog separately, then add the row.
  *
+ * ## Why this file changed again (objectui#3603)
+ *
+ * A second scheme-bearing shape that is decidable here, and the exact mirror of
+ * the self-repo blob URLs above: **this site's own absolute URLs**.
+ *
+ * `judgeHref()` skipped every href carrying a scheme (`EXTERNAL_HREF_RE`), with
+ * `SELF_REPO_BLOB_RE` as the single exception. So
+ * `https://www.objectui.org/docs/guide/plugins` — a route on the very site this
+ * repo publishes, whose whole route table is already enumerated above to serve
+ * the `/docs/...` and `/...` branches — was never resolved, while the identical
+ * route written `/docs/guide/plugins` was checked strictly. The origin is the
+ * only difference between the two, and it is the one part of a URL this script
+ * can be certain about.
+ *
+ * **Not a package-README special case, and deliberately not written as one.**
+ * The blind spot lives in `judgeHref()`, so it was never confined to any
+ * surface: `content/docs` carries 6 site-absolute URLs of its own and the root
+ * `README.md` 5, and all 11 were unchecked until now. Stripping the origin and
+ * handing the rest to `routeExists()` fixes the class everywhere at once, which
+ * is also why it needs no new rule and no new scan root.
+ *
+ * Both host spellings are live in this tree (`www.objectui.org` and bare
+ * `objectui.org`), so both are accepted; every other origin stays external and
+ * remains lychee's problem. Because what survives the strip is an ordinary
+ * absolute site path, it inherits BOTH branches of `routeExists()` unchanged —
+ * `/docs` strictness included. `https://www.objectui.org/docs/guide/plugins.md`
+ * is rejected for precisely the reason `/docs/guide/plugins.md` is.
+ *
+ * Measured before landing: 11 site-absolute URLs across today's surfaces, zero
+ * dead. The #3572 shape again — the check arrives green, its backlog already
+ * paid.
+ *
+ * ### Measured and NOT bought: the package READMEs (objectui#3622)
+ *
+ * objectui#3603 asked for a second half: growing the scan surface by the 38
+ * package READMEs, which is where the 9 dead links that prompted it lived.
+ * Those 9 are fixed by hand in the same PR. The scan row is **not** added, and
+ * the reason is this file's own rule from #3572 — measure the surface, pay its
+ * backlog separately, then add the row.
+ *
+ * (Note for whoever writes that row: a glob naming each package README cannot
+ * be spelled inside this block comment, because the star-slash in it closes the
+ * comment. Say it in prose here, or move the note outside.)
+ *
+ * The surface was measured, and its backlog is not the 9. With the resolution
+ * above in place, a `disk`-rule row covering those 38 files
+ * reports **11 more** dead links in five packages that card never touched:
+ * `/api/core`, `/api/react`, `/api/components` (no such routes — the class
+ * #3490 swept), `/docs/core`, `/docs/fields`, `/docs/layout` (real directories
+ * with no index page, so no route), `/docs/types` and `/examples` (neither
+ * exists), plus two disk paths that are simply absent
+ * (`../../docs/SHADCN_SYNC.md`, `./LICENSE`).
+ *
+ * Three of those deserve naming, because objectui#3603's own verification
+ * script scored them GREEN: it accepted a bare DIRECTORY as a fumadocs
+ * candidate. This gate does not, and is right not to — `routeCandidates()` has
+ * no such spelling, and the pinned test "rejects a relative link to a directory
+ * that has no index page" is that decision. `content/docs/core/` really has no
+ * index page, so `/docs/core` really does 404. The class is 20 links, not 9.
+ *
  * ## Code spans are stripped before scanning
