Patch Changes

• 22013aa: Split the overloaded managedBy: 'system' bucket into engine-owned vs. admin-writable, and enforce engine-owned writes (ADR-0103, #3220). The system bucket conflated two incompatible write policies: rows a platform service owns end to end (never user-written), and platform-defined schema whose rows are legitimately admin/user-writable. It carried the same all-false affordance row as better-auth/append-only but, unlike better-auth, had no engine enforcement — a wildcard admin could raw-write these rows through the generic data API (ADR-0049 gap).

  Rather than add a new managedBy enum value (which would fall through to fully-editable platform defaults on already-deployed Console clients), the write policy is now the resolved affordance (resolveCrudAffordances = bucket default + userActions), and engine-owned is defined as a system/append-only object that grants no write:

  • Writable set declares userActions — the RBAC link tables (sys_user_position, sys_user_permission_set, sys_position_permission_set), sys_user_preference, sys_approval_delegation, and the messaging config grids (sys_notification_preference / …_subscription / …_template) now declare userActions: { create, edit, delete: true }. The affordance is a declaration only — the DelegatedAdminGate / RLS / permission sets remain the authz.
  • Engine-owned objects locked to reads — apiMethods: ['get','list'] added where absent (jobs, notifications, approval request/approver/token/action, sys_record_share, sys_automation_run, mail/settings/secret audit, the messaging delivery pipeline). sys_secret is explicitly read-locked (an empty apiMethods array fails open).
  • sys_import_job stays engine-owned: the REST import route now writes its job rows isSystem-elevated (attribution preserved via the explicit created_by stamp) and the object is locked to ['get','list'].
  • New engine write guard (assertEngineOwnedWriteAllowed, plugin-security) fail-closed rejects user-context generic writes to engine-owned system/append-only objects, keyed off the resolved affordance; isSystem and context-less engine/service writes bypass by construction. Wired into the security middleware alongside the other data-layer gates.
  • reconcileManagedApiMethods (objectql registry) now runs for every managed bucket, not just better-auth: any advertised write verb an object's resolved affordances forbid is stripped at registration with a warning (the drift backstop, ADR-0049).
  • /me/permissions clamp (plugin-hono-server) now clamps system/append-only as well as better-auth, so the client hint reflects permission ∩ guard.

  Potentially breaking: a downstream/third-party system object that advertised generic write verbs relying on today's fail-open behaviour will have those verbs stripped (with a warning) and user-context generic writes to it rejected. Declare userActions opening the verbs the object legitimately takes from a user context. better-auth keeps plugin-auth's identity write guard unchanged; the row-level managed_by provenance vocabulary (ADR-0066) is a different axis and is untouched.

• 62a2117: Split the overloaded managedBy: 'system' bucket with an explicit engine-owned value (ADR-0103 addendum, #3343). ADR-0103 deferred the enum split ("revisitable later as a rename") because a new managedBy value would fall through to the fully-editable platform default on deployed Console clients. Both reasons against it are now retired — the server-side write guard / apiMethods reconciliation / /me/permissions clamp make that fallthrough cosmetic (the write is rejected regardless of what the client renders), and objectui#2712 closed the UI union — so v16 lands it, additively.

  • New enum value engine-owned with the same all-locked default affordance row as system (create/import/edit/delete: false, exportCsv: true). It joins ENGINE_OWNED_BUCKETS (the engine write guard) and GUARDED_WRITE_BUCKETS (the /me/permissions clamp); the guard, reconcileManagedApiMethods, and the clamp mechanisms are unchanged — engine-owned is an explicit member of the set they already covered by resolved affordance.
  • 20 objects relabelled system → engine-owned — the ones the engine owns end to end and that declared no write-opening userActions (the metadata store, jobs, approval runtime rows, sharing rows, sys_automation_run, the messaging delivery/receipt pipeline, sys_secret, settings). One-line, behaviour-identical per object.
  • 8 admin/user-writable objects keep managedBy: 'system' (the RBAC link tables, sys_user_preference, sys_approval_delegation, the messaging config grids) — system now reads as "engine-managed schema, writable via userActions".

  Behaviour-, enforcement- and wire-identical: resolved affordances, the guard verdict, the 405 apiMethods reconciliation, and the permissions clamp are the same before and after — this is a self-documenting relabel, not a policy change. No data migration (managedBy is schema metadata) and no code branches on the 'system' literal. Retiring the overloaded system entirely (moving the 8 writable objects to a dedicated bucket) is a breaking rename deferred to v17.
