Seeds run only when `system_menu` exists, fail when a fixed ID is occupied by a different permission, and deliberately assign no role.

+- Category draft create/revise, activate, and archive commands manage only current-tenant `TENANT_OWNED` rows. Subject ownership is server-validated against active PUBLIC or same-tenant Subjects; student category discovery requires `publication_status='ACTIVE'` and `is_active=true`.
+- Practice Blueprint draft create/revise, activate, and archive commands support only bounded `NODE` and `COLLECTION` modes. Exactly one target is selected by the request, while `entry_id`, effective node, tenant/scope, eligible/total counts, and lifecycle are server-controlled.
+- NODE blueprints require an existing ACTIVE visible current-tenant Content Node and count current-tenant Published Questions on that node. COLLECTION blueprints require an ACTIVE current-tenant Manual Question Collection and derive counts from its maintained membership count.
+- Both aggregates use `DRAFT → ACTIVE → ARCHIVED`, one monotonic `authoring_version` CAS, immutable ACTIVE content, terminal ARCHIVED state, transactional actor/version/status audit, append-only audit tables, and fail-before-mapper `JAVA_READ` authority checks.
+- Separate Category and Practice Blueprint author/publish/archive permissions are conditionally seeded by V4120 without assigning any role. PUBLIC/platform-curator writes remain unavailable.
+- Student blueprint lookup uses one availability query across the blueprint, Content Node, Content Entry, and optional Collection so draft, archived, or route-unavailable blueprints fail closed.
+- `V4120__add_category_and_practice_blueprint_authoring.sql` is the only new migration version and was executed by focused real-PostgreSQL tests.
+
+## Remaining exclusions after EDU-010
+
+EDU-010 intentionally does not deliver PUBLIC/platform-curator authoring, Content Entry authoring, Question Bank authoring, dynamic/filter blueprints, mixed or descendant-node blueprint selection, type/difficulty-specific authoring semantics, paid/private entitlement enforcement, Retire/restore transitions, per-member score/required flags, legacy asset/import workflows, or administrative list/detail/delete endpoints. Category remains a separately discoverable catalog aggregate and is not a Question relationship; Question classification continues through Placement.

 - `mvn -pl yudao-module-education clean test` with the five `EDU_TEST_POSTGRES_*` variables pointed at the local Docker PostgreSQL: **502 tests passed**, including 20 Flyway migration tests and nine lifecycle/placement PostgreSQL integration tests. V4090 was actually executed in disposable PostgreSQL schemas.
 - The lifecycle integration tests prove concurrent double-publish has one success and one lifecycle conflict with exactly one publish audit, cross-tenant and PUBLIC management fail closed, and `draft → publish → archive` matches student visibility.
