+
+fix(cli): `os validate` refuses a `views:` container whose own `name` disagrees with the object it binds to, the stack the server refuses at boot (#20331)
+
+Clause-②: yes
+
+A view container is registered under the object it binds to. When its own `name`
+is set to something else, for example `{ name: 'order_line', object: 'my_app_order_line', list: { … } }`,
+the server refuses the whole stack at boot. `os validate` used to pass that stack
+at exit 0, so the first sign of the mistake was a server that would not start.
+
+`os validate` now runs the same check the server runs at boot and prints the same
+message. The text form and `--json` both exit `1`. The `--json` failure payload lists
+one `errors` entry per refused container, with `path` (for example `views[0]`, or
+`packages[1].manifest.views[0]` in a multi-package stack), `code: 'VALIDATION_ERROR'`,
+`httpStatus: 400` and `message`. Every other exit, and the success payload, are
+unchanged.
+
+**Fix:** remove the container's `name`, or set it to the object name the message names.
+
+**New in `@objectstack/objectql` (the widening):** two new exports on the package's
+root entry, `viewContainerNameRefusal(container, sourceLabel, ownerId)` and its
+return type `ViewContainerNameRefusal`. The function returns the refusal the boot
+registrar throws, or `undefined`. It returns `undefined` for a container whose
+derived object key is empty, because the boot registrar skips that entry with a
+warning and never refuses it. The boot registrar now calls this function. What it
+refuses, its message and its `VALIDATION_ERROR` / `400` envelope are unchanged.
+
+Not changed: `os build` does not run this check, so it still writes an artifact
+carrying such a container, and the server refuses that artifact when it loads it.

+/**
+ * `os validate`'s author-time half of the boot registrar's divergent
+ * view-container `name` refusal (#20331).
+ *
+ * ## The defect
+ *
+ * A `views:` container whose own `name` disagrees with the object key it binds
+ * to — `{ name: 'order_line', object: 'my_app_order_line', list: {…} }` — is
+ * refused at boot by `ObjectQL.registerMetadataCollections` (#7378 row 1).
+ * `os validate` had no counterpart, so it exited 0 on that stack and
+ * `os serve` then refused it. `os validate` is the author-time judge of what
+ * the runtime will accept (NORTH-STAR road step ①), and a green validate
+ * followed by a boot refusal is the silent-validator shape.
+ *
+ * ## One judge, not a second rule
+ *
+ * {@link viewContainerNameRefusal} is `@objectstack/objectql`'s, the SAME
+ * function the boot registrar throws the answer of. ⛔ Not an `@objectstack/lint`
+ * rule and not a re-spelling of the check here: a twin agrees with the
+ * runtime only until one of the two is edited, which is the drift this card
+ * exists to close. What this module owns is the WALK — which `views:` entries
+ * boot judges, and under which package id — and nothing about the verdict.
+ *
+ * ## The walk is the boot path's
+ *
+ * `AppPlugin` hands the manifest service `{ ...stack.manifest, ...stack }`;
+ * `resolveArtifactPackageOrder` returns that payload itself when it carries no
+ * `packages` key and each `packages[i].manifest` body otherwise (ADR-0130 D4);
+ * `ObjectQL.registerApp(body)` then runs `registerMetadataCollections(body,
+ * body.id || body.name, 'manifest')`. So:
+ *
+ *   - no `packages[]` → the top-level `views`, owned by the manifest's id;
+ *   - `packages[]`    → each body's own `views`, owned by that package's id,
+ *     and ⛔ NOT the top level, which the load path does not register from.
+ *
+ * The package id is read through the owners that already exist for it: the
+ * runtime's `artifactPackageId` (`@objectstack/core` — "every seam that has to
+ * name a package reads the id through THIS function") for the one-package
+ * payload, and this package's `artifactPackages` for `packages[]`, the reader
+ * both `os build` and `os validate` already walk with.
+ *
+ * ⚠️ Bound, stated rather than hidden: a nested `plugins[]` entry's `views` is
+ * registered by boot too (label `nested plugin`), and is NOT walked here. The
+ * stack schema types `plugins` as `unknown[]` — in an authored config they are
+ * runtime plugin instances, not metadata bundles — so this door has no parsed
+ * shape to walk there.
+ *
+ * Reads the PARSED stack — what `defineStack()` hands the boot wrap, and what
+ * `os build` serializes.
