ART-07A1: define exact reviewer packet membership

[Abiorh001]

Change

ART-07A1 — Exact reviewer packet membership contract

Goal

Define the artifact membership needed for normalized reviewer packet storage and correct the prerequisites for shared acceptance.

Intent And Planning Context

Bounded change record owns intent, allowed files, design, acceptance criteria and risks.

The approved order is ART-07A1 types → REV-03B packet storage → complete REV-04A Review storage → shared REV-04B FinalAcceptance → CON/shared fence → shared acceptance operation. Automated acceptance can still be the first complete runtime path.

What Changed

One strict, frozen ART metadata contract and a type-only async port identify the exact Submission ZIP and ordered original guide documents. Exact Submission, aggregate checker result, locked guide/snapshot and activated setup run/generation are required. Current navigation reflects the corrected sequence.

Why It Changed

Shared acceptance references Review records that do not exist yet. Normalized packet storage needs exact ART member identities first. Skipping these prerequisites would require incomplete source records or parallel acceptance implementations.

Design Chosen

Separate member types preserve the existing Submission and guide binding owners. Reuse canonical roles and the PROJECTS public media-type scalar. Reject private extras, coercion in Python values, mismatched echoed scope, duplicate identities and unordered documents. JSON round-trip remains supported.

Alternatives Rejected

No incomplete Review table, automated-only acceptance variant, opaque binding set, compatibility alias, provider access or speculative output-file member.

Scope Control

Allowed Files Changed

The record lists the exact ART API, focused tests, additive ownership/lane inventories and current documentation paths.

Files Outside Stated Scope

None.

Product Behavior

• No Workstream product behavior changed.

No resolver, database table, byte capability, route, AUTH activation or acceptance operation is added.

Result Summary

197 focused tests passed; lint, boundaries, ownership, links, stale wording and Commitrail passed. Production/test bytes are unchanged by the final documentation-only push. Full hosted verification passed on d82eb9f8: 8,073/8,073 tests completed across all nine lanes, zero skips/deselections. Backend run 36929780928 passed. Independent artifact audit verified tested merge-tree equality with the PR head, exact inventory conservation, evidence/coverage digests and database/S3 cleanup.

Acceptance Criteria Proof

• Exact field inventories and private-extra probes protect the metadata boundary.
• Every echoed scope substitution is concealed; removing its guard fails the tests.
• Required member counts, independent uniqueness and canonical order are tested; guard-removal probes fail.
• Native Python UUIDs/tuples are enforced; old coercion and outer-strictness-removal probes fail at the intended assertions, with valid controls.
• Existing owner and lane inventories are retained; adjacent unauthorized additions/missing test modules are rejected.
• Current roadmap and navigation distinguish delivered types from future resolver/storage/authority.

Test Delta

Tests Added

25 packet-contract cases and one exact additive ownership regression. Pure shape and transport proof only.

Tests Modified

Existing lane catalogue proof explicitly includes the new module. Existing test assertions are retained.

Tests Removed Or Skipped

None.

Impact-Routed Reviewer Results

Code reviewed at e3b00d050d2e6b76d102623af4fba59869acaf51, 2026-10-01. Final d82eb9f8 changes only one AUTH overview sentence; production, tests and inventories are byte-identical. Affected docs/product review replayed on that final head. These summaries mirror internal session evidence, not an authorization source.

Reviewer	Result	Findings	Proof boundary and uncertainty
Architecture / reuse	PASS AFTER FIXES	Strict UUID finding closed	Exact owners/public seam; no runtime resolver or cycle
Security	PASS	None	Privacy and all scope substitutions; no stored-ownership claim
QA / test delta	PASS AFTER FIXES	Outer strict-container proof closed	Exact-head isolated mutation probes fail after valid controls
Docs / product operations	PASS AFTER FIXES	Sequence consistency and external wording fixed	Final-head navigation and both acceptance branches agree
CI integrity	PASS WITH LOW RISKS	None	Final-head tested tree, 8,073-node completeness, digests and cleanup verified; shared A took 1103.415s under unchanged 1200s cap

External Review

CodeRabbit substantively reviewed e3b00d05. Its sole code-review finding was an AUTH-003 next-boundary wording omission, fixed in d82eb9f8 and independently re-reviewed internally. No unresolved GitHub review threads. Latest-push CodeRabbit status is not fresh: rate-limited. Its substantive review of e3b00d05 and the internally verified documentation correction are distinguished here. The description-format advisory is addressed here; docstring percentage is advisory and does not establish a product defect or repository gate.

CI And Gate Integrity

• No workflow, lint/test/docstring gate or package-script weakening.
• No new GitHub Action or checkout change.
• No runner, timeout, service, skip, coverage gate or lane-count change.
• Tests protect failure boundaries; coverage remains diagnostic.

Remaining Risks

Valid shape and echoed-request equality do not prove canonical stored ownership or complete membership. The future resolver and normalized persistence need real database isolation and lineage proof. No current bytes or authority are granted by these values. Hosted runtime still misses the advisory timing target; no timeout or gate was relaxed.

Follow-Up Work

REV-03B normalized packet persistence, followed by complete REV-04A Review storage. No next chunk is started by this PR.

Human Review Focus

Inspect exact setup-generation scope, distinct binding owners and corrected storage prerequisites. No local spreadsheet exports are present.

📝 Walkthrough

Walkthrough

The change adds a strict, metadata-only review-packet membership contract and exposes its types through the artifacts API. It adds contract and ownership tests, and updates planning documents to place packet persistence and Review storage before shared FinalAcceptance storage.

Membership contract and validation backend/app/modules/artifacts/api/review_packet.py, backend/app/modules/artifacts/api/__init__.py, backend/tests/artifacts/test_review_packet_contract.py, .commitrail/initiatives/WS-ART-001/WS-ART-001-07A1.md, docs/architecture_data_model.md, docs/spec_artifact_storage_service.md, docs/spec_review_lifecycle.md	Adds frozen, strict models for request scope and required Submission and guide members. Adds a type-only async membership protocol, exports the new types, and tests validation, ordering, uniqueness, and request matching. The contract does not add a resolver or byte-access capability.
Ownership and test-lane registration .ci/behavior-ownership/partition.v1.json, backend/scripts/behavior_ownership.py, backend/scripts/test_lane_catalogue.py, backend/tests/test_behavior_ownership.py, backend/tests/test_ci_lane_catalogue.py	Assigns the new API path to the artifacts group and adds its contract test to the shared test catalogue. Adds tests for both registrations.
Storage and activation sequencing .commitrail/INDEX.md, .commitrail/initiatives/..., README.md, docs/engineering/authorization_activation_custody.md, docs/roadmap_status.md	Updates initiative and roadmap records to place REV-03B packet persistence and complete REV-04A Review storage before shared REV-04B FinalAcceptance storage and later composition or activation work.

List packet and Review storage in the next boundary.

The durable index defines REV-03B packet storage and REV-04A Review storage as the next steps before the shared foundations. This overview’s next-boundary sentence starts at those foundations, so it can direct implementation past the required storage steps.

Suggested fix

-- Next usable boundary: continue canonical boundary recovery through the shared
-  REV/CON/fence foundations and later ARCH-04E1B/04E2/04E3 routing sequence.
+- Next usable boundary: continue canonical boundary recovery through REV-03B
+  packet and REV-04A Review storage, then the shared REV/CON/fence foundations
+  and later ARCH-04E1B/04E2/04E3 routing sequence.
