+**BREAKING** accept-set narrowing, shipped as `minor` under the repo's launch-window convention for breaking changes (ADR-0131 D3, D9).
+
+- **The exemption is withdrawn.** When a seed load names no organization (`config.organizationId`), the loader stamps the install's sole organization on every row of an object that carries an `organization_id` column. Seeds of `sys_`, `cloud_` and `ai_` objects used to be exempt as "intentionally global" and landed NULL. There are no platform-global seeds left, so they now carry the organization too: a seeded `sys_business_unit` is the organization's own business unit.
+- **No owner, no row.** When the load names no organization and the install holds none, or holds several, a row of an object that carries an `organization_id` column is refused, counted in the result's errors and named in the message. Nothing of it is written. Before this change those rows were written NULL. A row that sets its own `organization_id` still loads.
+- **No column, no stamp.** A row of an object with no organization column (`tenancy: { enabled: false }`, or a platform object whose injected column was dropped) is written without one, whether the organization was named by the load or derived. Before this change such a row was stamped anyway, and the engine refused it as an unknown field, so the row was lost.
+- **Unchanged.** A load that names its organization (the per-organization replay under a walled posture) stamps it on every row that carries the column, as before. A composition that registers no organization object at all keeps loading its seeds unstamped. Rows written before this change keep their bytes; attributing that residue is ADR-0131 C7's.
+
+**The remedy.** Under the `single` posture the Default Organization exists before seeds load, so a boot seed always has its owner. A load that is refused names the organization it needs: pass it as `config.organizationId` (the organization the seed populates on a walled deployment), or set `organization_id` on the record.

+- **Before.** Under the `single` posture, in a composition that registers the organization object, a system-context insert on a tenant-scoped object with no organization anywhere landed with `organization_id` NULL when the install held no organization yet. That was the normal state of a first boot: the organization arrived with the first sign-up.
+- **Now.** The Default Organization is a boot invariant under `single` (ADR-0131 D3): `@objectstack/plugin-auth` creates it before the application seeds load and before the server accepts a request. An install that registers the organization object and holds none of it therefore has no owner to derive, and the insert is refused with `ERR_SYSTEM_WRITE_ORGANIZATION_REQUIRED` (status 500, `reason: 'no-organization'`). The message names the missing organization. Nothing is written.
+- **Unchanged.** Exactly one organization is derived and stamped. Several organizations, or a walled posture, are refused as before. A write that carries an organization, on the execution context or on the record, is never refused. Objects with no organization column, objects declaring `tenancy: { enabled: false }`, and federated objects are outside the rule. The platform-namespace objects the tenancy inventory has not admitted keep their per-object exclusion; ADR-0131 C8 retires it. A composition that registers no organization object at all (a lean embedding) still lands the write unstamped.
+
+**The remedy.** On a `single` deployment, the refusal means the Default Organization is missing: restart, and the auth plugin recreates it at boot, or carry the organization on the write (`{ context: { isSystem: true, tenantId } }`, or `organization_id` on the record). A TypeScript caller of `resolveSystemWriteOrganization` passes whether its composition registers the organization object.

+**BREAKING** boot and accept-set narrowing, shipped as `minor` under the repo's launch-window convention for breaking changes (ADR-0131 D3).
+
+- **A boot invariant.** Under the `single` posture (the posture in force, so a degraded walled request counts), the auth plugin's `start()` finds or creates the Default Organization (`slug: 'default'`), with or without a platform admin. Every application plugin starts after it. Before this change the organization was created on `kernel:ready` only once a platform admin existed, so on a fresh deployment it arrived with the first sign-up, after the seeds had loaded with no owner.
+- **A failure stops the boot.** If the organization cannot be created, or the store cannot be read, `start()` throws and the deployment does not boot. Before, the bootstrap logged a warning and the deployment served anyway. An install holding several organizations and none with `slug: 'default'` gets no new organization; the boot logs it and continues.
+- **`autoDefaultOrganization: false` no longer means "no organization".** It now turns off only the platform admin's owner bind. A host that set it to keep an organization-less `single` deployment gets the Default Organization anyway: under `single` no row is organization-less.
+- **Every user belongs to it from the first boot.** Because the organization exists before anyone signs up, the membership reconciler binds every new user (under the `auto` membership policy) to it as `member` the moment they are created, so every session carries it as the active organization. Before, a user created before the first admin carried none. The one-time membership backfill likewise has its target at the first `kernel:ready`.
+- **The first admin is the owner.** That includes the first admin, whom the reconciler binds as `member` before the owner bind learns they are the platform admin. While the one-time owner bind is undecided and the Default Organization has no owner, the bootstrap promotes that `member` row to `owner` in place and records the decision as `promoted`. A decided bind, an existing owner, or a membership elsewhere is never touched.
+- **The in-memory driver answers `503` until C8.** `@objectstack/driver-memory` refuses tenant-scoped reads, and every session now carries the Default Organization, so under `single` its signed-in reads answer `503` until ADR-0131 C8 (#15212, D8) gives `single` no read predicate. The platform admin met the same refusal before this change, once the Default Organization existed. A SQL driver (`connection: { filename: ':memory:' }` for an in-process store) serves the deployment meanwhile.
+
+**The remedy.** If the boot stops on the Default Organization, make the `sys_organization` insert land: check the datasource's write permission and connectivity, and whether a legacy unique index on `slug` refuses `default`. A host relying on `autoDefaultOrganization: false` for an organization-less `single` deployment has no such deployment any more; run a walled posture if organizations are meant to be absent until created.

+
+- **What `bootStack` boots now.** Under `single`, `@objectstack/plugin-auth` creates the Default Organization before the seeds load, so every boot has one, and `bootStack` no longer turns off the platform admin's owner bind. The harness admin is the Default Organization's `owner`, every user a fixture signs up is its `member`, and their sessions carry it as the active organization. This is the shape `objectstack dev` and `objectstack serve` boot. Before, `bootStack` pinned `autoDefaultOrganization: false` and booted a `single` stack with no organization at all, a shape no deployment runs after this release.
+- **`orgContext` asserts, it no longer switches.** `orgContext: true` keeps its refusal: the boot fails when the harness admin holds no membership, and it still refuses to compose with `multiTenant`. The bind itself happens on every boot.
+- **Unchanged.** `multiTenant` boots a walled posture as before, and the open default-organization bootstrap still abstains under it.
+
+**The remedy.** A fixture that needs a principal outside the organization's `org_member` domain removes that user's membership (an administrator's act a real deployment performs) instead of booting without an organization. A fixture that minted its own `slug: 'default'` organization reads the one the boot created. A fixture that ran on `databaseDriver: 'memory'` and signs a user in meets the memory driver's tenant-scope refusal (`503`) until ADR-0131 C8; run that leg on the SQL in-memory driver.
