feat(scope): unattributed and all org targets

Adds a first-class org target vocabulary shared by every rule kind: a
specific organization, unattributed (objects whose org is NULL), or all.
A role can now be granted the unassigned pile without a global rule.

- rules.scope gains 'unattributed' and 'all'
- user_rules.org_id accepts NULL to target unattributed objects
- org_in_scope partitions the classes: 'unattributed' matches only a NULL
  target, tree scopes never match one
- has_permission(user, activity, view) capability probe for UI gating
- current_org_filter() parses morbac.org_ids once into org UUIDs plus the
  unattributed-bucket flag (a JSON null element requests it)
- rls_check split by arity so NULL never carries two meanings:
  rls_check(activity, view) for tables with no org column,
  rls_check(activity, view, row_org_id[, row_user_id]) where a NULL
  row_org_id means the record is unattributed
- detect_rule_conflicts is scope-aware, so rules targeting different
  object sets no longer collide

+without granting anything org-wide:
+
+```sql
+INSERT INTO morbac.rules (org_id, role_id, activity, view, context_id, modality, scope)
+SELECT o.id, r.id, 'read', 'documents', c.id, 'permission', 'unattributed'

+JOIN morbac.contexts c ON c.name = 'always'
+WHERE o.name = 'Acme Corp';
+```
+
+Choose which records a query returns:
+
+```sql
+SET morbac.org_ids = '[null]';              -- unattributed only (attribution queue)
+SET morbac.org_ids = '["<org-uuid>", null]';-- that org plus unattributed
+SET morbac.org_id  = '<org-uuid>';          -- that org only
+-- nothing set                              -- everything authorized, unattributed included

 **`get_org_scope(org_id, scope, max_depth?)`** is the underlying helper — it returns `(org_id, depth)` rows and can be used directly when you need to iterate over an org set. An optional `p_max_depth` limits traversal depth.
 
+### Unattributed (no-org) Objects
+
+An object whose `org_id` is `NULL` is **unattributed**: it belongs to no organization, typically because it is awaiting attribution. This is the only meaning `NULL` carries in the org dimension — it never means "any org" and never means "all orgs".
+
+#### The org target vocabulary
+
+Every rule kind selects its target the same way. There are exactly three targets:
+
+| Target | Role-based (`morbac.rules`) | User-level (roleless) |
+|---|---|---|
+| A specific organization | `scope` = `'self'`, `'subtree'`, … | `user_rules` with an `org_id` |
+| Unattributed objects | `scope` = `'unattributed'` | `user_rules` with `org_id = NULL` |
+| All orgs (unattributed included) | `scope` = `'all'` | `global_rules` |
+
+The two object classes are **partitioned**: an `'unattributed'` rule can never reach an object that has an org, and the tree scopes (`'self'`, `'subtree'`, …) can never reach an unattributed object. Only `'all'` and `global_rules` deliberately span both.
+
+#### Granting a role access to unattributed objects
+
+The declaring org is the policy authority; the role must be held **in that org**. Grant, revoke, and delegate the role exactly as usual — access to the unattributed pool follows.
+
+```sql
+INSERT INTO morbac.rules (org_id, role_id, activity, view, context_id, modality, scope)
+SELECT o.id, r.id, 'read', 'documents', c.id, 'permission', 'unattributed'
+FROM morbac.orgs o
+JOIN morbac.roles r ON r.org_id = o.id AND r.name = 'triage'
+JOIN morbac.contexts c ON c.name = 'always'
+WHERE o.name = 'Acme Corp';
+```
+
+Several organizations may each declare their own policy over the same unattributed pool — that is ordinary Multi-OrBAC: independent authorities over a shared object space.
+
+Prohibitions, priorities, contexts, temporal validity, role hierarchy, delegation, derived roles, negative assignments and SoD all apply unchanged:
+
+```sql
+-- block the same role during an embargo, outranking the permission
+INSERT INTO morbac.rules (org_id, role_id, activity, view, context_id, modality, scope, priority)
+SELECT o.id, r.id, 'read', 'documents', c.id, 'prohibition', 'unattributed', 10
+FROM morbac.orgs o
+JOIN morbac.roles r ON r.org_id = o.id AND r.name = 'triage'
+JOIN morbac.contexts c ON c.name = 'embargo'
+WHERE o.name = 'Acme Corp';
+```
+
+Granting a single user access without a role uses `user_rules` with no org:
+
+```sql
+INSERT INTO morbac.user_rules (user_id, org_id, activity, view, context_id, modality)
+SELECT '…user…'::uuid, NULL, 'read', 'documents', c.id, 'permission'
+FROM morbac.contexts c WHERE c.name = 'always';
+```
+
+#### Checking authorization
+
+`is_allowed(user, org, activity, view)` takes a specific org, or `NULL` for an unattributed object:
+
+```sql
+SELECT morbac.is_allowed(user_id, NULL, 'read', 'documents');  -- unattributed object
+```
+
+Unattributed decisions are **never cached** (the cache is keyed by a non-null org), so they always reflect current policy.
+
+#### Selecting which records to return
+
+`rls_check` has two forms, distinguished by arity so that a `NULL` never carries two meanings:
+
+```sql
+morbac.rls_check(activity, view)                              -- table has no org column
+morbac.rls_check(activity, view, row_org_id [, row_user_id])  -- row-scoped by org
+```
+
+In the row-scoped form, `row_org_id` is the record's org and a `NULL` value means the record is unattributed. The 2-argument form carries no org dimension and evaluates against the session org context.
+
+Which records come back is chosen with the session variables. A JSON `null` element in `morbac.org_ids` names the unattributed bucket:
+
+| Session | Returns |
+|---|---|
+| *(nothing set)* | all authorized records — every org **and** unattributed |
+| `morbac.org_id = '<uuid>'` | that org only — unattributed excluded |
+| `morbac.org_ids = '["<uuid>"]'` | those orgs only — unattributed excluded |
+| `morbac.org_ids = '[null]'` | **unattributed only** (the attribution queue) |
+| `morbac.org_ids = '["<uuid>", null]'` | that org **plus** unattributed |
+
+```sql
+-- the attribution queue: only records awaiting an org
+SET morbac.org_ids = '[null]';
+SELECT * FROM app.documents;
+```
+
+`morbac.current_org_filter()` is the underlying parser; it reads `morbac.org_ids` once and returns the real org UUIDs plus whether the unattributed bucket was requested.
+
+#### Capability probe for UI gating
+
+To decide whether to show a feature at all — rather than authorize a specific object — use:
+
+```sql
+SELECT morbac.has_permission(user_id, 'read', 'documents');
+```
+
+It returns TRUE when the user is allowed in **any** context: any org they are a member of, the unattributed bucket, or via global rules. Prohibitions are honored per context. It is not a substitute for object-level `is_allowed()`; a pure cross-org grant into a non-member org is not counted.
