feat(platform-objects): sys_organization's data door admits update, column-gated by the ADR-0092 D2 whitelist (#16687)

* feat(platform-objects): admit update on sys_organization's data door, column-gated by the ADR-0092 D2 whitelist (#15873)

Ruling (a), decision batch #64, 2026-09-07 — the data door admits `update`
and the identity write guard's per-object whitelist does the column gating.
`enable.apiMethods` becomes ['get', 'list', 'update'] with the
`userActions.edit` affordance the registry reconciler requires; better-auth's
own columns (name / slug / logo / metadata) are readonly per ADR-0092 D4 and
stay refused/stripped by the guard. create / delete still 405; no bulk
(recorded in SINGLE_RECORD_WRITE_ONLY).

Pins: declaration (platform-objects), column gate + D4 partition derived from
the shipped whitelist (plugin-auth), and the real door with the 405 → 403
transition (dogfood).

* test(dogfood): mint the door test's organization through better-auth under the walled posture

The plain showcase boot holds no sys_organization row (system-context read
returns []; the admin session has activeOrganizationId null), and
organization/create is denied without an organization wall (#5261) — so the
fixture boots multiTenant: 'posture-only' and creates the org the way the
Setup app does.

* test(dogfood),spec,changeset: name the two derived surfaces the update grant moves (#15873 contract-review patch round)

Review FAIL was on the accept-set statement, not the code: granting `update`
also derives the update-mode import door (API_METHOD_DERIVATION: import =
any of create/update) and flips /auth/me/permissions for sys_organization
(allowEdit true, apiOperations gains update and import). Both named in the
changeset; pinned on the real door in the dogfood file (import: 200, timezone
lands, name stripped; better-auth-only row refused per row; insert mode 405
naming create; /me/permissions allowEdit true with update+import and a
sibling better-auth table as the clamp control); the SINGLE_RECORD_WRITE_ONLY
sentence now says what is true (bulk not granted; the derived import door
is, column-clamped per row).

+`sys_organization` admits generic `update` on the data door, column-gated by the ADR-0092 D2 identity write guard (#15873 — maintainer ruling 2026-09-07, decision batch #64, option (a), verbatim 「同意」).
+
+The organization table carries four platform-owned columns better-auth never reads or writes — `require_mfa` (ADR-0069 D3), `parent_organization_id` and `sort_order` (ADR-0105 D6), `timezone` (#14238). plugin-auth declares them generically editable (`MANAGED_EXTENSION_EDITABLE_FIELDS.sys_organization`, the guard's per-object update whitelist), while the object's `enable.apiMethods: ['get', 'list']` answered every `PATCH /api/v1/data/sys_organization/:id` with 405 `OBJECT_API_METHOD_NOT_ALLOWED` before the engine — and the guard — was reached. Declared editable, reachable from no product surface: the columns could be set only by a system-context caller. The ruling answers the card's question — yes, an administrator sets these columns through the product — and refuses the alternative of declaring them system-writable only.
+
+What widens (Clause ②) — three published surfaces move, all column-clamped by the same guard:
+
+1. The data door's accept set. `enable.apiMethods` becomes `['get', 'list', 'update']`, and `userActions: { edit: true }` declares the affordance ADR-0103 D3's `reconcileManagedApiMethods` requires before it lets a `managedBy` object keep a write verb at registration (without it the verb is stripped with a warning and the door keeps answering 405 — the second silent gate #7727 measured on `sys_api_key`). `PATCH /api/v1/data/sys_organization/:id` is admitted; `create` / `delete` still answer 405; `bulk` (`/batch`, the `*Many` routes) is not granted (recorded in `SINGLE_RECORD_WRITE_ONLY`).
+2. The derived `import` door. `API_METHOD_DERIVATION` (`@objectstack/spec` `api-derivation.ts`) derives `import` from `any: ['create', 'update']`, so granting `update` admits `POST /api/v1/data/sys_organization/import` (and the async `/import/jobs` route) in `writeMode: 'update'` — one request updates N rows, each row clamped per row by the ADR-0092 D2 guard under the caller's context (a row carrying only better-auth columns is refused `PERMISSION_DENIED`; `treatAsHistorical` does not elevate). Insert-mode and upsert-mode import stay 405 (the conjunct named is `create`). The door's own 405 envelope advertises the derived set in `allowed`.
+3. `/auth/me/permissions`. For a principal the permission layer already admits (the seeded platform admin's `admin_full_access` wildcard), `sys_organization.allowEdit` goes `false → true` (`clampManagedObjectWrites` reads `userActions.edit` for the `better-auth` bucket) and `apiOperations` gains `update` and `import` (`annotateEffectiveApiOperations`) — the payload the console renders its edit affordance from. `organization_admin` / `member_default` stay hard-denied on every better-auth table by `managed-object-write-denies.ts`, unchanged.
+
+What does not widen: the column set. The guard clamps every user-context update on this table to the whitelist. A PATCH of a better-auth column sent alone (`name`, `slug`, `logo`, `metadata`) is now refused by the guard's own verdict — 403 `PERMISSION_DENIED` — instead of the method gate's 405; sent beside a whitelisted column it is stripped and the whitelisted column lands. better-auth's own columns keep changing through better-auth's `organization/update` (the `update_organization` row action, unchanged). Per ADR-0092 D4's form-rendering constraint the four better-auth columns are now `readonly: true` on the object, so a standard edit form offers exactly what the guard admits; the engine's static-readonly strip exempts system-context writers, so better-auth's adapter is unaffected.
+
+Not breaking: no key, export or accepted value is removed; every request that succeeded before succeeds unchanged, and the 405 → 403 change applies only to requests that were refused before and are refused still.

+ * #15873 — `sys_organization`'s data door admits `update`, and nothing else on
+ * the declaration moved (maintainer ruling 2026-09-07, decision batch #64,
+ * option (a), verbatim 「同意」).
+ *
+ * The card: four platform-owned columns (`require_mfa`,
+ * `parent_organization_id`, `sort_order`, `timezone`) were declared generically
+ * editable in plugin-auth's `MANAGED_EXTENSION_EDITABLE_FIELDS` — the ADR-0092
+ * D2 identity write guard's per-object update whitelist — while this object's
+ * `enable.apiMethods: ['get', 'list']` answered 405 to every PATCH before the
+ * engine, and the guard, were ever reached. Declared editable, reachable from
+ * nowhere. The ruling widens the METHOD gate and leaves the COLUMN gate to the
+ * whitelist that already exists for exactly this.
+ *
+ * This file pins the DECLARATION, from source. Three things about it are each
+ * a way the widening could silently fail to be what was ruled:
+ *
+ *  1. the verb set is `update` and only `update` — `create` / `delete` stay
+ *     405 (organizations are minted and destroyed through better-auth's own
+ *     endpoints), and `bulk` is not granted (the ruling widened one verb; the
+ *     single-record-only choice is recorded in `SINGLE_RECORD_WRITE_ONLY`,
+ *     `@objectstack/spec`'s `api-methods-batch-conformance.test.ts`);
+ *  2. the verb SURVIVES registration. A `managedBy` object runs through
+ *     `reconcileManagedApiMethods` (objectql registry, ADR-0092 / ADR-0103 D3),
+ *     which strips any write verb the resolved affordances do not grant and
+ *     only warns — so `update` in `apiMethods` with no `userActions.edit` is a
+ *     declaration that serves 405 anyway (the second silent gate #7727 measured
+ *     on `sys_api_key`). The predicate the registry calls is asked here
+ *     directly, with a positive control proving it can still refuse;
+ *  3. better-auth's own door for its own columns is untouched: the row actions
+ *     still target `organization/update` with `name` / `slug` / `logo`.
+ *
+ * The RUNTIME half — that the real door answers 200 for a whitelisted column
+ * and 403 `PERMISSION_DENIED` (not 405, not 200) for a better-auth column — is
+ * `organization-update-door.dogfood.test.ts` in `packages/qa/dogfood`; the
+ * form-facing D4 partition (whitelisted columns writable, everything else
+ * `readonly`) is `sys-organization-update-door.test.ts` in plugin-auth, which
+ * derives it from the shipped whitelist rather than re-spelling it.
