WS-ARCH-001-CP04B: implement hidden policy publication lifecycle - #352
Merged
Conversation
📝 WalkthroughWalkthroughThe PR adds hidden contribution-policy publish and retire operations. It introduces typed authorization contracts, deterministic publication graphs, immutable transition custody, PostgreSQL enforcement, service orchestration, migration updates, integration tests, and CP04B planning documentation. ChangesContribution policy publication
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk:🟡 Moderate · up to The PR introduces hidden policy publication and retirement lifecycle behavior, but merge readiness is moderate because authorization parity and denial/isolation safeguards are not fully proven by the current tests, while custody constraint naming and recovery validation ordering leave bounded schema/runtime risks that should be fixed or explicitly accepted before merge.

- Around line 73-78: Rewrite the truncated CONTRIBUTIONS adapter sentence so it
clearly states that the adapter constructs the existing AUTH public facts using
the same values required by public AUTH ContributionPolicyPublishFacts or
ContributionPolicyRetireFacts, without importing AUTH models, repositories,
services, or private helpers.
In `@backend/app/modules/contributions/models.py`:
- Around line 361-409: The CheckConstraint names in
ContributionPolicyTransitionCustody do not match migration 0007; update the
request_digest and event_type constraints to use the migration’s physical names
ck_contribution_policy_custody_digest and
ck_contribution_policy_custody_event_type.
In `@backend/app/modules/contributions/service.py`:
- Around line 77-84: Validate required projects and bindings before recovering
existing operations in publish and retire, or reject missing ports during
initialization, so recovered events cannot bypass port guards; add replay tests
covering this behavior. Because ContributionPolicyPublicationService captures
the repository at construction, keep its repository synchronized whenever
service._repository is replaced in tests.
In `@backend/tests/contributions/test_policy_publication_auth_parity.py`:
- Around line 32-42: Fix both AUTH parity assertions in
backend/tests/contributions/test_policy_publication_auth_parity.py: lines 32-42
must derive the expected digest from the seeded draft graph via
publication_graph_facts, then compare it with the digest built from
service-produced facts; lines 82-91 must derive the expected digest from the
seeded request identities, then compare it with the service-produced facts
digest. Ensure expected and actual use independently sourced facts rather than
the same auth_facts object.
In `@backend/tests/contributions/test_policy_publication_authorization.py`:
- Around line 299-305: Strengthen
test_closed_publication_authority_cannot_be_reused by asserting the recorded
prepared objects are distinct and that each is closed exactly once, rather than
checking membership in the list slice after a single publish. Use the existing
fixture.authorization.closed records to verify the observable non-reuse
behavior.
In `@backend/tests/contributions/test_policy_publication_concurrency.py`:
- Around line 59-80: Update _start_paused_publication and _finish_publication to
clean up reliably on setup or publication-task failure: cancel and await the
task when authorization.entered times out or setup raises, and ensure
_finish_publication always releases the authorization, exits the transaction,
and closes the session even when await task raises. Preserve the original task
exception while retrieving cancellation exceptions safely.
In `@backend/tests/contributions/test_policy_publish.py`:
- Around line 184-189: The test named test_caller_supplied_graph_mismatch_denies
does not exercise a denial path; rename it to reflect that it verifies
ContributionPolicyPublishRequest cannot carry caller graph facts, and update the
related chunk contract test map to reference the new name.

Outcome
Implements WS-ARCH-001-CP04B hidden ContributionPolicy publication and retirement behavior at exact head
fb38524662f32f63e1489fc47a9cd7b1fa5f8957over current main5c4a471eba764306432424e310fc733b62724960.Hosted verification
shared_foundations_a.0007's canonical ORM-aligned constraint names.Internal exact-head review
The full production change received architecture, security, product/operations, QA, test-delta, CI-integrity, senior-engineering, reuse/dedup, and documentation review. The final rollback-proof correction was replayed only through its affected tracks: security, QA, test-delta, CI-integrity, and documentation. Those tracks PASS on exact head
fb385246; unchanged architecture/product/reuse conclusions remain applicable because the corrective delta changed only test evidence and its review note. No unresolved Critical, High, or Medium finding remains.The strengthened QA probe proves the rollback test fails when publication failure is moved before PostgreSQL staging, while the normal transaction test passes and verifies custody, lifecycle state, and staged AUTH evidence are all rolled back.
External review
CodeRabbit produced seven substantive findings earlier in the PR. Each was independently replayed, fixed where valid, tested, and resolved. All review threads are resolved. Its final check was manual-review-skipped, so it is recorded as not fresh and is not represented as substantive approval.
CI integrity and uncertainty
No workflow, package script, coverage threshold, test selection, skip policy, or failure propagation was weakened. Hosted PostgreSQL artifacts provide execution custody for database and concurrency proof; the final merge-ref tree is identical to the exact reviewed head. Human approval remains the only unavailable authority.
Human review focus
Please focus on server-owned graph truth, owner-port validation before recovery, lock order through authorization consumption, close-before-product-effect ordering, publication/retirement custody, immutable PostgreSQL history, recovery authorization, and confirmation that no action or route was activated.
Only an authorized human may approve and merge this PR.
