+fix(lint)!: a view container whose `object` names no object is refused by `os validate`, `os build` and `os lint` (`object-reference-unknown`), and the refusal names the namespace-prefixed object when that is the one the stack declares (#20216)
+
+Clause-②: no (narrowing)
+
+**BREAKING** — an accept-set narrowing on one authored key, shipped as `minor` under the
+launch-window convention (`check-changeset-no-major` refuses `major` until GA; breaking-ness
+is carried by this banner and the ADR-0087 disposition below, not by the level).
+
+**What changed.** `ViewSchema.object` is how a stack-level `views: [...]` container says
+which object its views belong to, and it is the key the runtime indexes views by
+(`getViewsByObject()` / `GET /meta/view?object=`). The schema declares it `z.string()`, and
+nothing resolved it: `defineStack`'s cross-reference check reads a container's
+`list.data` / `form.data` bindings, never the container's own key. So a container bound to a
+name no object carries passed: `os validate` printed "Validation passed" and exited 0,
+saying nothing about the view, and `os build` / `os lint` run the same rule table. At
+runtime none of its views was found for any object. The common case is not a typo but a
+missing namespace prefix — `object: 'order_line'` in a project whose object is
+`my_app_order_line` — which is exactly what `os generate view` wrote in every namespaced
+project until its template learned the prefix.
+
+The key now joins `validateObjectReferences` and rides the ladder every other object-name
+site on that rule uses, resolved against the same set as a field's relationship target:
+
+1. the stack's own objects, or an object an entry of the artifact's `packages[]` provides → ok;
+2. a known platform object (`PLATFORM_PROVIDED_OBJECT_NAMES`) → ok;
+3. unresolved and not platform-prefixed → **`error`** `object-reference-unknown` at
+   `views[N].object`, so `os validate` / `os build` / `os lint` exit 1;
+4. unresolved, platform-prefixed, registered by nothing → the existing
+   `object-reference-unregistered-platform` advisory.
+
+The refusal lists the objects the stack does declare, and when the bound name is exactly a
+declared object minus the stack's `manifest.namespace` prefix, the hint names that prefixed
+object outright. Not judged, on purpose: a container that carries no `object` (its binding
+then falls back to `list.data.object` / `form.data.object` / its `name`, a different
+reference), and a container authored at runtime (this rule does not run on a `view` write at
+the runtime publish gate; that door is unchanged).
+
+## The accept set, before and after
+
+This is a behaviour table, not a rewrite: the FROM column is what the door did, the TO
+column is what it does now.
+
+| where | FROM | TO |
+|:--|:--|:--|
+| `os validate`, `os build`, `os lint` on a view container bound to a name no object carries | exit 0, no finding | exit 1, `object-reference-unknown` at `views[N].object` |
+| the same, on a platform-prefixed name nothing registers | exit 0, no finding | the `object-reference-unregistered-platform` advisory, exit unchanged |
+| a runtime `view` write | unchanged | unchanged |
+
+Nothing an author writes changes spelling, and no key or value is retired. A container that
+is refused was already dead at runtime; the finding's own hint says which object to bind it
+to.
+
+<!-- adr-0087: not-required (no-migration-prescription) Nothing authorable moves: `packages/spec` is untouched, `ViewSchema.object` keeps its key, its type and its legality, and no stored metadata representation changes shape, so `objectstack migrate meta` has nothing to rewrite and the ledger has no row to gain. What narrows is the set of VALUES the author-time rule accepts for a reference that must resolve to a declared object, and which declared object an author meant is a fact about their stack, never something a mechanical conversion can derive; the refusal carries its own correction. The other categories are closed on facts: `@objectstack/lint` publishes (not `unpublished`); no ADR-0087 id covers it (not `registered` / `already-registered`); and the change is rule behaviour, not a TypeScript declaration (not `runtime-interface-only` / `type-surface-only`). -->
