+Tests and test-config only, no shipped code touched: the catalog "entries use their own
+plugin" pin in `examples/schema-catalog/test/catalog-gallery-render.test.tsx` is
+generalized from the two hand-enumerated categories objectui#5113 and objectui#5856 left
+it at (`plugin-view`, `plugin-grid`) to all thirteen `plugin-*` catalog categories.
+
+The `category -> type` map is now DERIVED from the `register()` calls, by reusing
+`deriveRegistryKeys` from `scripts/check-doc-component-types.mjs` and joining its
+registration sites on the `packages/<dir>` that owns them — the same derivation
+`scripts/regenerate-known-schema-types.mjs` already consumes. The value is a SET, which
+`plugin-charts` requires (its entries author `chart` and `bar-chart`), and the rule stays
+per entry rather than per category.
+
+objectui#5113's RENDER half (a record that exists only in the gallery data source reaches
+the screen) does not transfer to the eleven categories that author their data inline, so
+it is replaced for them by a MOUNT half rather than degraded to the STRUCTURE half:
+substituting every own-plugin node with an inert probe must put the probe's marker on
+screen, which a stray node, a `type` that is not a node, and a node behind a satisfied
+`hidden` cannot do. Data provenance is kept, unweakened, for the entries that bind to an
+object the gallery fixture serves — derived per entry from `objectName`, not declared. The
+gate states its own coverage split so breadth cannot be read as depth: 5 entries carry
+structure + mount + data, 34 carry structure + mount, and `plugin-editor` / `plugin-map`
+lose nothing to their `EXCLUSIONS` because the probe replaces the renderer that needs
+Monaco and WebGL2.
+
+The derivation earned its keep on its first run: the filing's hand-written table read
+`plugin-form form`, and `form` is registered by `packages/components`, not by
+`@object-ui/plugin-form`. Both `plugin-form` entries are the third instance of
+objectui#5113's class, ledgered against objectui#6167 with a case asserting they still
+fail, so the ledger cannot rot green.
+
+`examples/schema-catalog/tsconfig.test.json` gains `allowJs` (with `checkJs` off) and a
+repo-root `rootDir`, the same answer `tsconfig.scripts.json` reached in objectui#3494 for
+importing a plain-JS CI helper into a typed pin test.
