Change

Canonical public API field drill — work in progress, not ready to merge.

Goal

Complete endpoint-by-endpoint external-client proof for the selected 29 canonical
public operations. Obsolete route removal belongs to the task agent; hidden and
unfinished lifecycle APIs are excluded. Keep this work in the same PR.

Intent And Planning Context

Existing combined change record
owns scope, criteria and review routing. The human authorized the two reproduced
NUL request-validation repairs in this same PR, followed by continued drilling.

What Changed

  • Preserve the optional review/revision policy and exact successor/hash probes.
  • Require exact unauthenticated health JSON.
  • Compare all stable self-profile fields after accepted/rejected updates; validate
    admission timestamps without incorrectly requiring them to remain unchanged.
  • Probe context selectors, exact contributor actions, revoked access and a stored
    foreign project.
  • Strengthen actor administration response fields, lifecycle receipts, replay,
    UTF-8 reason bounds and unchanged target state after rejected inputs.
  • Preserve two newly reproduced product defects as failing cases and repair handoffs.
  • Repair both NUL boundaries in their existing public validators, preserving
    authorization and project-ID lookup. Slugs are not project-ID aliases.
  • Deepen identity-link lifecycle input and full-state readback probes.
  • Compare the complete 73-permission catalogue and five-role scope/permission
    matrix against frozen client expectations shared by both drill entry points.
  • Compare complete administrative grant provenance and timestamps before and
    after issue/revoke replay, retaining independent stored-state snapshots.

Evidence

  • Clean 54f73438: real Uvicorn/Flow-verifier/PostgreSQL drill completed 377 cases,
    173 successful and 204 expected denials, no failures.
  • Separate fresh-database probe at the same head: embedded NUL in each of the two
    self-profile editable fields returned 503, expected 422. Four successful
    controls/readbacks confirmed unchanged business fields. Both databases/roles
    were cleaned up. Private reports remain under /tmp/workstream-field-drill.l3LIo4/;
    API-DRILL-007
    records portable inputs and repair criteria.
  • Clean 4e8e8020: the expanded live run completed all 417 current probes:
    196 success, 218 expected denials, and three failures (the two profile fields
    plus a NUL authorization-context project selector). Database/role cleanup passed.
    Suspended self GET correctly passes; suspended PATCH and deactivated GET/PATCH
    are denied. The preceding 321cb0b6 run aborted on our incorrect suspended-GET
    expectation; it is not passing evidence.
  • Current d0fa2f9c only strengthens the selector expectation to require
    error.retryable: false and adds a discriminating helper test. All 33 helper
    tests and Ruff pass. The 417 live probes retain their actual 4e8e8020 target.
  • Markdown links, Commitrail, stale wording and stale authorization documentation
    checks passed locally. The last check fixes the previous hosted wording failure.
  • Clean repair 1bf08b9c: all 417 live probes pass (196 success, 221 expected
    denials), including all three previously failing inputs; database cleanup passed.
  • A separate targeted live probe caught an incorrect new test assumption that
    project context supports slug aliases. The current test/docs preserve ID-only
    lookup and expected slug 404; no lookup behavior was added.
  • 43675025: 78/78 targeted live probes pass (35 success, 43 expected
    denials), including repaired mixed-field input, ID-only selectors/concealment
    and full identity-link lifecycle/replay readbacks. Isolated cleanup passed.
    Product repair code and other full-run probes are unchanged from 1bf08b9c.
  • 394c8f82: 65/65 targeted actor probes pass (44 success, 21 expected
    denials), with monotonic suspended self-read timestamps and exact administrative
    readback. Both CodeRabbit comments are fixed and resolved. The settings test
    restores its temporary identity environment before clearing the cache.
  • Current 60ab7447: all 35 helper tests pass. The independent catalogue drill
    passes 9/9 cases with database cleanup. The expanded twenty-actor drill passes
    444/444 checks (338 successes, 106 expected denials), including ten owner-guard
    probes, with no incomplete groups and complete database cleanup. This count
    includes HTTP, CLI and local evidence checks, not 444 HTTP requests.
    Focused review and all hosted checks pass, including seven backend lanes and
    final aggregate/protected coverage. No product code changed in this extension.
  • Local pytest regression execution was blocked before assertions by the existing
    schema-fingerprint fixture on PostgreSQL 17. CI uses PostgreSQL 16; no guard was
    bypassed and that fixture error is not counted as a passing test.

Product Behavior

  • Product changes are limited to NUL rejection in self-profile fields and the
    context query. No migrations, authorization rules, CI configuration or coverage
    thresholds changed.
  • No provider calls, product SQL writes, hidden route activation or guard bypass.

Impact-Routed Reviewer Results

Focused security/QA/test-delta/docs review passed at exact 43675025 for the
NUL repairs and resumed identity-link group. QA-CANON-001, QA-NUL-002 and
QA-LINK-001 are closed. The reviewer independently rejected a timestamp-only
replay mutation and retained exact passing controls. All 33 helper tests pass.
Live evidence is mapped to its two actual targets above; this does not certify
the unfinished 29-operation checklist.
The affected CodeRabbit corrections also passed focused replay at 394c8f82,
including the exact 65-case actor artifact. Reviewers have completed.
The catalogue/grant extension passes security, QA/test-delta and documentation
review at 60ab7447, including independent ordering/timestamp falsification
probes and inspection of both exact-head live artifacts. No findings remain
in this bounded extension. It does not certify the full 29-operation checklist.
Reviews of 743f5406 remain historical for affected changed behavior.

External Review

CodeRabbit substantively reviewed 43675025 and raised two minor findings;
both are corrected at 394c8f82, replied to and resolved. Its newest check is
rate limited, not a new substantive review. All hosted checks for 394c8f82
passed, including seven backend lanes and aggregate/protected coverage. Hosted
merge target 33b68cf6 has parents c69ff853 and 394c8f82; downloaded project
lane evidence confirms all three named NUL regressions completed successfully.
This closes the PostgreSQL execution gap from the local PG17 fixture error.
All latest hosted checks also pass at 60ab7447; no new CodeRabbit threads
were posted and the two existing threads remain resolved. The rate-limited
status is not presented as a substantive review of this extension.

Remaining Risks

API-DRILL-007 and API-DRILL-008 are repaired and their live probes pass. The complete
29-operation checklist is not finished. A passing aggregate or an operation with
one successful case is not full field certification. Do not merge this work as
a completed MCP handoff.

Human Merge Ownership

Human approval and merge remain required after the work and review are complete.

Merge Risk: 🔵 Low · up to 43675

The change adds NUL-input rejection and expands public API contract checks. The remaining risk is limited to test isolation and incomplete detection of timestamp regressions in the suspended self-read scenario.

Explanation

Docstring coverage is 40.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 35 functions across 5 files. (4 skipped: 4 unsupported.)

Full details: Description check

Explanation

The description provides substantial context, evidence, product behavior, review status, risks, and merge ownership. However, it omits several template sections and required details, including Why It Changed, Design Chosen, Alternatives Rejected, Scope Control with allowed files, Acceptance Criteria Proof, Test Delta, CI And Gate Integrity, Follow-Up Work, and Human Review Focus. It also does not use the required reviewer-results table.

Resolution

Add the missing template headings and complete each section. List the allowed files and any files outside scope, document the design and rejected alternatives, map acceptance criteria to evidence, list added/modified tests, record CI and gate-integrity checks, add follow-up work and human review focus, and provide the required impact-routed reviewer-results table with reviewer, result, findings, and proof boundaries.

- Line 851: Update the checks around the suspended self-read to capture the
pre-read updated_at and last_seen_at values from current, then require both the
self-read result and subsequent admin baseline to be at least those captured
values, rather than only validating against timestamp_value. Preserve the
existing checks structure while enforcing monotonic timestamp advancement.

In `@backend/tests/test_api_drill_repairs.py`:
- Line 93: Update the teardown around get_settings.cache_clear() so the
environment is restored first and the settings cache is cleared afterward.
Ensure cached authorization settings from the test do not persist into later
tests, using the existing get_settings symbol.
