+The liveness ledger's `/meta` cache-flag, per-item switch, doc and book rows cite the code that reads their keys where it now lives
+
+Clause-②: no (only the rows' evidence paths and notes move and every status stays `live`: `MetadataEndpointsConfigSchema`, `DocSchema` and `BookSchema` accept exactly what they accepted before, and no state count moves)
+
+- `liveness/metadata_endpoints.json`: the `enableCache` row and the `if (metadata.endpoints.item !== false)` half of the `endpoints.item` row cited `packages/rest/src/rest-server.ts#registerMetadataEndpointsInner`. `@objectstack/rest` moved the per-item reads to `packages/rest/src/meta-item-read-routes.ts#registerMetaItemReadRoutes` with no behaviour change, so those references follow them. The `registerPerItemRoute` half of the `endpoints.item` row keeps its citation: that call still lives in the inner method's head.
+- `liveness/doc.json`: the `content` row's single-item branch, and the `_note`'s book-tree and single-item branches, cite the new module. The `doc` list branch keeps its citation.
+- `liveness/book.json`: the `_note` names the new module for the `book/:name/tree` branch.
+- The quoted code, the producers, the verdicts and the row notes are unchanged.

+The `/meta` per-item read routes live in their own module, with no route, handler or answer changed
+
+Clause-②: no (a move: the four routes per base, their place in the `/meta` registration order, every handler, every response and the anonymous-deny gate in front of them are unchanged, and the published declarations are byte-identical)
+
+- `RestServer#registerMetadataEndpointsInner` keeps its name, docblock, place and head. The statement that registers `GET {metaPath}/:type/:name/references`, `GET {metaPath}/:type/:name/layers`, `GET {metaPath}/book/:name/tree` and `GET {metaPath}/:type/:name` moved, re-indented, to `packages/rest/src/meta-item-read-routes.ts`, and the method calls it at its old position, inside the umbrella's guarded registration. The `metadata.endpoints.item` switch gates the same mounts.
+- Nothing to do for a consumer: no export of the package entry, no route, no configuration key and no response moved.
