## Remaining publication slice
## Publication-slice constraints (resolved)
Do not add a local-only admin write path while `SCALAR_READ` remains the default authoritative provider: a successful PostgreSQL write would not be visible to students. The next bounded slice is a `JAVA_READ`-only tenant question `draft → publish → archive → student read` path that fails closed in unsupported provider modes.
Do not add a local-only admin write path while `SCALAR_READ` remains the default authoritative provider: a successful PostgreSQL write would not be visible to students. The implemented bounded slice is a `JAVA_READ`-only tenant question `draft → publish → archive → student read` path that fails closed in unsupported provider modes.
Before its Flyway/application implementation, resolve and document:
The slice resolves the prerequisite decisions as follows:
1. the exact `DRAFT/PUBLISHED/ARCHIVED/RETIRED` state machine and mapping of V4020 `HIDDEN/INACTIVE` rows;
2. immutable question-version and transactional publication-audit ownership;
3. whether ancestor entry/node/collection/archive state makes a question unavailable to fresh student reads;
4. the explicit tenant-admin versus platform-curator permission/data-scope matrix.
1. the command surface is `DRAFTPUBLISHEDARCHIVED`; `RETIRED` remains undefined, and V4020 `HIDDEN/INACTIVE` rows map to `ARCHIVED`;
2. Education owns immutable question versions and transactional lifecycle audit;
3. a question's state controls direct visibility while entry/node/collection availability gates only route-specific discovery;
4. tenant admin action permissions are separate, tenant-wide, and tenant-bound; platform-curator/PUBLIC writes fail closed in this slice.
## Delivery progress — JAVA_READ tenant-question lifecycle slice (2026-07-30)
Delivered:
- Explicit Admin APIs and independent RBAC permissions for tenant question author, publish, and archive operations. Requests cannot choose tenant, scope, lifecycle, or actor identity:
- `POST /admin-api/education/questions/drafts``education:question:author`;
- `PUT /admin-api/education/questions/{id}/publish``education:question:publish`;
- `PUT /admin-api/education/questions/{id}/archive``education:question:archive`.
- Provider-authority guard: authoring is accepted only for `JAVA_READ`; `SCALAR_READ` fails before any Mapper access.
- V4080 changes native defaults to `DRAFT/false`, normalizes legacy visibility states, fails closed on unsafe historical published content, constrains the single direction `DRAFT → PUBLISHED → ARCHIVED`, creates immutable Question Content Versions, and creates append-only lifecycle audit facts.
- V4080 adds the Question Version → Question reference as the twentieth guarded catalog edge. In addition to the generic scope rule, a version's tenant and scope must exactly equal its question's ownership; the version table is the twelfth catalog table protected against ownership mutation.
- When the adopted platform schema contains `system_menu`, V4080 conditionally seeds the Education capability plus author/publish/archive permissions. A fixed ID already occupied by a different permission aborts migration, and no role assignment is seeded.
- Publication and archive use tenant/scope/expected-state CAS updates and append audit facts in the same transaction. Audit failure rolls back the state change.
- PostgreSQL integration-test coverage exercises the student read-after-write seam: draft is invisible, published content is returned only through the existing Safe Question projection, and archived content is invisible while stored snapshots remain independent.
- Direct question visibility is controlled by the question lifecycle. Container availability is a route-level discovery gate; classification, collection, and platform-curator write paths remain outside this bounded slice.
Permission and data-scope matrix is recorded in `07-decisions.md`. The three lifecycle endpoints manage tenant-wide shared catalog assets within the current framework tenant; department/self DataPermission does not grant additional row access, PUBLIC authoring fails closed, and the V4080 seed intentionally grants no role.
The listed acceptance criteria are satisfied for the native catalog graph and tenant-question lifecycle slice. EDU-010 remains in progress because its tenant-admin outcome also includes classification, collection, blueprint, retire, and platform-curator workflows that are not part of this bounded slice.
## Verification evidence (2026-07-30)
- `mvn -pl yudao-module-education test` with the five `EDU_TEST_POSTGRES_*` variables pointed at the local Docker PostgreSQL: **485 tests passed**, including 18 Flyway migration tests and five lifecycle PostgreSQL integration tests. V4080 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.
- The real Spring Method Security contract tests prove each of author/publish/archive requires its own permission and rejected calls do not reach the lifecycle service.
- `mvn -pl yudao-server -am -DskipTests clean compile`: **22 reactor modules passed**.
- `git diff --check`: passed.
- `target/classes/db/migration/education/V4080__add_question_publication_lifecycle.sql`: present after the module build.
