Chunk

WS-QUAL-002-PLAN — repository-wide behavior ownership catalogue planning.

Goal

Define durable reviewed test ownership and a safe, changed-line-aware path for any future mutation reactivation without restoring the retired callable-wide 05M workflow.

Intent And Planning Context

AUTH and other contributors should not pause implementation to rediscover owning tests. PR #289 retired the blocking mutation workflow after callable-wide selection mutated unchanged executable lines. This PR records the replacement architecture and bounded chunk contracts; it implements no runtime behavior.

What Changed

  • Added intent, discovery, plan, risks, decisions, status, and eight bounded chunk contracts.
  • Defined canonical .ci/behavior-ownership/partition.v1.json custody and exact population boundaries.
  • Defined protected-base ownership, stable behavior identities, validated remaps, structural-only records, and exact test-run evidence.
  • Kept context discovery local/manual with no added workflow.
  • Reserved mutation reactivation for a separately approved final chunk using exact changed executable spans.
  • Closed all nine CodeRabbit contract findings.

Design Chosen

A durable catalogue is separate from transient PR selection. Existing ownership comes from protected base; PR-head data is additive for new or validated remapped behavior. Population chunks consume one digest-bound partition and cannot edit parent or sibling contracts. Future mutation input must contain exact changed spans, never callable names alone.

Scope

Only .agent-loop/initiatives/WS-QUAL-002-behavior-ownership-catalogue/** changes. No backend application code, migration, workflow, coverage threshold, product lifecycle, authorization behavior, payment, or reputation behavior changes.

Evidence

  • git diff --check — passed.
  • python3 scripts/check_markdown_links.py — passed.
  • python3 scripts/check_stale_workstream_wording.py — passed.
  • python3 scripts/check_stale_authorization_docs.py — passed.
  • Architecture review — PASS.
  • QA review — PASS.
  • CI-integrity review — PASS.
  • Documentation review — PASS.
  • Reuse/dedup review — PASS.

Acceptance Proof

  • Canonical versioned partition path, schema identity, digest, and protected-base custody are explicit.
  • Chunk allowed paths cannot modify parent or sibling contracts.
  • Candidate evidence rejects stale, partial, skipped, deselected, or digest-invalid runs.
  • Real filesystem, S3/MinIO, PostgreSQL, archive, adapter, and outbox boundaries require real evidence where applicable.
  • Structural-only records and remaps have machine-testable fail-closed rules.
  • Final mutation input consumes exact changed executable spans and rejects unchanged sibling lines.
  • Retired workflow, selectors, and historical claim authority remain blocked from active configuration.

Test Delta

Planning Markdown only. No product test was removed, skipped, deselected, or weakened. The contracts require new validator and negative tests during their respective implementation chunks.

Reviewer Results

Architecture, QA, CI integrity, documentation, reuse/deduplication, senior engineering, security, and product/operations reviews passed or passed with documented low implementation cautions. CodeRabbit findings were incorporated and revalidated.

CI Integrity

No active workflow changed. Backend lanes, coverage floors, lint, Agent Gates, branch protection, CodeRabbit, and human merge remain unchanged. Chunk 02 explicitly forbids workflow changes. Chunk 05 requires one stable always-emitted check, no workflow path filters, and internal not_applicable preflight before dependency installation.

Risks

False ownership, stale partitions, narrowed protected evidence, duplicate effective owners, and callable-wide regression all fail closed. Mutation remains inactive until a separate human-approved reactivation chunk passes exact-head hosted evidence.

Follow-Up

After this plan merges and the human approves implementation, begin only WS-QUAL-002-01. Do not start later chunks automatically.

Human Review Focus

Review partition custody, remap single-owner resolution, structural-only schema rules, narrowed chunk scopes, and changed-span mutation input.

Human Merge Ownership

Summary by CodeRabbit

  • Documentation
    • Added planning, discovery, decision, risk, and status records for the behavior ownership catalogue initiative.
    • Defined seven implementation chunks covering catalogue foundations, evidence gathering, ownership reviews, completeness checks, and future mutation enforcement.
    • Documented scope, validation requirements, review responsibilities, protected boundaries, partitioning, and stop conditions.
    • Clarified that implementation and mutation reactivation have not started and require human approval.
    • Recorded rollout prerequisites, fail-closed safeguards, and concurrency guidelines for future work.

In
@.agent-loop/initiatives/WS-QUAL-002-behavior-ownership-catalogue/chunks/WS-QUAL-002-01-catalogue-foundation.md:
- Around line 57-60: The catalogue foundation must define and protect one
canonical, versioned machine-readable partition artifact, including its path,
schema version, and custody rules. Update the acceptance criteria and related
`WS-QUAL-002-03A` through `WS-QUAL-002-03D` work so every branch consumes that
immutable artifact, while validation rejects missing, relocated, branch-local,
or modified copies.
- Around line 31-41: Restrict each chunk’s Allowed files section so chunks
cannot modify parent or sibling contracts: in
.agent-loop/initiatives/WS-QUAL-002-behavior-ownership-catalogue/chunks/WS-QUAL-002-01-catalogue-foundation.md
(lines 31-41), permit only foundation outputs plus explicitly approved
status/evidence files; apply the corresponding context-evidence restrictions in
WS-QUAL-002-02-context-evidence.md (lines 17-25), and limit
WS-QUAL-002-03A-auth-ownership.md (lines 17-21),
WS-QUAL-002-03B-artifact-ownership.md (lines 17-21), and
WS-QUAL-002-03C-lifecycle-ownership.md (lines 17-21) to their respective
ownership outputs and approved status/evidence files.

In
@.agent-loop/initiatives/WS-QUAL-002-behavior-ownership-catalogue/chunks/WS-QUAL-002-02-context-evidence.md:
- Around line 31-37: Update the artifact whitelist acceptance criterion to
preserve exact test-run custody: include lane identity, collection and
completion status, skip/deselect status, and an artifact digest or immutable
manifest reference, matching the contract in
WS-CI-001-02B-exact-custody-semantic-test-lanes.md. Keep the prohibition on
secrets and sensitive runtime data, and ensure stale, partial, skipped, or
overwritten coverage cannot be treated as valid candidate evidence.

In
@.agent-loop/initiatives/WS-QUAL-002-behavior-ownership-catalogue/chunks/WS-QUAL-002-03B-artifact-ownership.md:
- Around line 30-34: Update the acceptance criteria in
.agent-loop/initiatives/WS-QUAL-002-behavior-ownership-catalogue/chunks/WS-QUAL-002-03B-artifact-ownership.md
lines 30-34 to require applicable filesystem, S3/MinIO, archive, and
external-adapter boundary evidence, not mocked-only tests. Update the acceptance
criteria in
.agent-loop/initiatives/WS-QUAL-002-behavior-ownership-catalogue/chunks/WS-QUAL-002-03C-lifecycle-ownership.md
lines 30-34 to require applicable database and outbox evidence for transaction,
idempotency, revision, and concurrency behavior.

In
@.agent-loop/initiatives/WS-QUAL-002-behavior-ownership-catalogue/chunks/WS-QUAL-002-03D-shared-ownership.md:
- Around line 31-34: Define a machine-readable structural_only status and
required reason in the ownership record contract used by _read_claim; reject
callable and test fields for that status while preserving callable/test
requirements for executable records. Update --run-owned-tests and the validator
to exclude structural_only records, and add a completeness test covering the
no-executable-callable case documented in DISCOVERY.md.
- Around line 20-25: Update the validator’s partition-loading logic for the
shared ownership targets defined by WS-QUAL-002-01 to read only from the
protected base or an approved foundation commit, never the population PR’s
working tree. Detect changes to that machine-readable partition in population
PRs and fail closed before validation, preserving the fixed no-overlap scope.

In
@.agent-loop/initiatives/WS-QUAL-002-behavior-ownership-catalogue/chunks/WS-QUAL-002-05-mutation-reactivation.md:
- Around line 35-38: Extend the selection contract around changed_callables() in
backend/scripts/mutation_policy.py to include each changed executable line or
span alongside its containing callable. Update the mutation runner to consume
these changed-line spans when constructing its final mutation input, rather than
selecting whole callables. Revise the negative test to inspect and reject the
runner’s final mutation input when unchanged executable sibling lines are
included.

In @.agent-loop/initiatives/WS-QUAL-002-behavior-ownership-catalogue/PLAN.md:
- Around line 61-70: Update the rollout-boundary plan to require a blocking
pre-reactivation check that scans workflows, scripts, and configuration for
references to the retired callable-wide workflow and its selectors, rejecting
any matches. Keep 05M retired until this validation passes alongside the
existing hosted-evidence requirements.
- Around line 37-40: Update the behavior-ownership plan to define remap
resolution before protected-base selection: specify stable callable identity,
how a PR-head remap supersedes the old protected-base record without narrowing
ownership, and validation that produces exactly one effective owner for every
changed line. Preserve additive PR-head semantics and the exact Git delta as the
changed-callable source.
