+feat(metadata-protocol,runtime,service-automation,spec)!: the metadata protocol refuses every organization-scoped write, and an uninstall is environment-wide (ADR-0131 D6/D12)
+
+Clause-②: yes (narrowing)
+
+<!-- adr-0087: registered metadata-write-organization-scope-refused, package-uninstall-environment-wide -->
+
+**BREAKING, in both directions.** It narrows: an organization-scoped metadata write is refused, and request keys retire. It widens one refusal: a package uninstall naming neither `organizationId` nor `allTenants`, refused before with `400 TENANT_SCOPE_REQUIRED`, is now accepted and runs environment-wide. Graded `minor` on the v18 prerelease line: Changesets is in pre mode with the tag `next`, and the fixed group is already majored by the line's opening marker, so this ships in an `18.0.0-next.N`.
+
+ADR-0131 D6 retires the per-organization overlay axis. The `/meta` doors already carry no organization; now the metadata protocol itself refuses an organization-scoped write from every door, and the per-organization write path behind it is deleted.
+
+**What changes.**
+
+- Every protocol write that names an organization is refused with `403 NOT_OVERRIDABLE`, before anything is read or written, for every metadata type and every tenancy posture. This covers `saveMetaItem` (draft and publish), `publishMetaItem`, `deleteMetaItem`, `rollbackMetaItem`, `revertCommit`, `rollbackToPackageCommit`, `publishPackageDrafts`, `discardPackageDrafts`, `revertStoredPackage`, `duplicatePackage` and `reassignOrphanedMetadata`. The message's first sentence names the tenancy posture in force. The five types that declared `allowOrgOverride` (`view`, `dashboard`, `report`, `translation`, `email_template`) and the `OS_METADATA_WRITABLE` hatch no longer open an organization scope.
+- The audit ledger (`sys_metadata_audit`) and the commit ledger (`sys_metadata_commit`) record `organization_id` NULL.
+- The `/packages` doors of the runtime dispatcher thread no organization into any verb: publish-drafts, discard-drafts, the commit list, commit revert, rollback, revert, adopt-orphans, duplicate, delete, and the package manifest read.
+- `deletePackage` retires its `organizationId` and `allTenants` request keys and both `400 TENANT_SCOPE_REQUIRED` refusals. The dispatcher's `DELETE /api/v1/packages/:id` no longer refuses an operator with no active organization. An uninstall removes every row bound to the package in this environment. Who may uninstall is the door's operator gate, as before.
+- A seed published with a package no longer takes the publisher's active organization: a seed dataset names the organization it populates (ADR-0131 D9).
+
+**What moves for consumers.**
+
+| From | To |
+|:--|:--|
+| `organizationId` on a `SaveMetaItem` / `PublishMetaItem` / `DeleteMetaItem` request (`@objectstack/spec`) | drop it: the write lands environment-wide. The key is stripped at a spec parse (the schemas are not strict) and refused at the protocol: a request still naming one answers `403 NOT_OVERRIDABLE` |
+| `organizationId` on any other protocol write verb's request | drop it, same refusal |
+| `deletePackage({ packageId, organizationId })` or `deletePackage({ packageId, allTenants: true })` | `deletePackage({ packageId })`; either retired key answers `400 INVALID_REQUEST` and removes nothing |
+| `DeletePackageRequest.organizationId` / `.allTenants` (`@objectstack/metadata-protocol`) | gone from the type |
+| `UninstallCleanup`'s `organizationId` argument | gone; a cleanup receives `{ packageId, actor? }` |
+| `TENANT_SCOPE_REQUIRED` in the error-code ledger | retired; no producer emits it |
+| `findPlatformScheduleOrgGaps`' `organizationId` input | gone: every write is platform-level |
+| a `seed` draft whose records carry no `organization_id`, relying on the publisher's active organization under `group` | set `organization_id` on each record (ADR-0131 D12, item 12); under `group` a seed record that names no organization is refused at load, and under `single` the loader still derives the Default Organization |
+
+**What a deployment observes.**
+
+- Rows stored organization-scoped before this release are not touched by any write. `POST /meta/_migrate-stored` reports each one as `skipped` and names the promotion ceremony (ADR-0131 C7); the stored-flow credential move reports such a flow as not moved (`NOT_OVERRIDABLE`) and logs that its credential is still in cleartext in that row — rotate it. A legacy organization-scoped draft is no longer promoted, discarded or reverted by a package verb, a commit recorded in a legacy organization layer is refused by `revertCommit`, and `duplicatePackage` and adopt-orphans copy or adopt the environment's rows only.
+- An uninstall removes the package's legacy organization-scoped rows with it, as the declared cross-tenant uninstall did.
+
+**What does not change.** The protocol's reads still accept an organization and still serve legacy organization rows; that narrowing is a later stage. The anonymous form doors' read of the Default Organization's layer is unchanged.

By default every object schema served by `/meta` and `/metadata` is projected onto the fields the **calling user** may read, so a field they cannot read does not appear at all — not its name, label, type, picklist options, formula, `visibleWhen` predicate, `defaultValue`, or the `requiredPermissions` capability guarding it. Set to `1` to serve the full schema to every authenticated caller, as releases before this one did. This changes **disclosure only**: the data plane still masks values and refuses forbidden writes either way, and the console reads field affordances from `/auth/me/permissions`, so toggling it never changes UI correctness. The REST layer also honours a per-server `metadata.maskObjectFields: false`; this variable is the deployment-wide knob and covers the runtime `/metadata` dispatcher, which has no REST config to read. |

It **never opens an item a managed package ships**: managed content is sealed ([ADR-0131](https://github.com/objectstack-ai/objectstack/blob/main/docs/adr/0131-total-organization-ownership-no-null-organization-id.md) D6), so an overlay or a removal of a shipped flow, object, field, permission set, position or any other type without an environment overlay is refused with `403 NOT_OVERRIDABLE` whether the hatch is set or not.
