2026-09-29 — Plan preparation and bounded source review

User request: review the supplied test audit against Coding-Standards and write an implementation plan. Implementation was not requested in this turn.

Source: PR head 8260489e8e3ad6b7e170bbf7bd411bac90758abd; actual hosted merge fa7c4f9d5edee0a94baf6fff0ed29452ffaff7db; equal tree c249e251efcf48ad13d4bfaf854cf496544bece7. Verified the retained source artifact's SHA-256 and inspected the current workflow and canonical standards.

Recovered the decoded job log: all 1,254 package tests report OK, with Engine alone taking 2,637.839s, review-evidence 4.501s, and the complete verifier passing 73/73 suites. Confirmed the successful run's 45m35s verification step, the failed earlier main run's 43m03s step, the audit's code findings, two fixture preparation policies, and 35 direct preparation call sites. Local diagnostic tests and collection probes are recorded with their environment limitations in the review.

Source changes: none. Remote mutations: none. This delivery adds only a proposed plan package in the working container, not in the repository or Library.

Current plan status: Planned. Acceptance: pending. Exactly one next slice: M0 — observable baseline and deterministic oracles. Independent review of the proposed implementation and hosted candidate performance remain future implementation acceptance, not claims made by this review.

No earlier plan was marked Accepted, and no performance savings were claimed for an unimplemented optimization.

2026-09-29 — Plan admitted; M0 started

The user selected this plan and requested implementation. Adopted the package on isolated branch implementation/test-ci-efficiency-m0, based on reviewed A1 head 8260489e8e3ad6b7e170bbf7bd411bac90758abd (tree c249e251efcf48ad13d4bfaf854cf496544bece7). The shared main worktree is at 149ba317e9397519bc181a048ecf76aef129a69c and contains unrelated uncommitted work. Those existing edits were left untouched; the plan package was added only under its previously clean docs/plans/ paths. The plan's reviewed source and accepted main are distinct. The A1-only digest assertions are present on this candidate and will be corrected there; no A1 semantics were transplanted to main.

The plan artifacts and link-only plan-index entry are applied. Source implementation awaits the requested Muse contributor: the available Passeur connection currently identifies /media/jeremy/OrangeCream/Linux Software/repos/owned/creative-media/Tuldok, so it cannot safely receive this repository's write assignment. No code was assigned to another model.

Plan status: In Progress; M0 source changes and acceptance evidence: pending. No tests or workflow runs were started by this admission step.

2026-09-29 — M0 candidate implementation and focused evidence

The implementation assignment above was superseded by the user's explicit direction to continue with GPT-6.1 Sol Low. Work remains isolated at /tmp/cs-test-ci-efficiency-m0, branch implementation/test-ci-efficiency-m0, based on 8260489e8e3ad6b7e170bbf7bd411bac90758abd (tree c249e251efcf48ad13d4bfaf854cf496544bece7). The main worktree remains at 149ba317e9397519bc181a048ecf76aef129a69c; its existing unrelated changes remain untouched.

M0 candidate changes preserve the engine job identity, exact source fetch/bundle, locked Python 3.12 install, pinned artifact action, all 13 unittest groups, their import contexts, and the complete verifier. The workflow now records source/runtime/lock/runner identity, per-test verbose duration output, command wall time/status, tee status, logs, JSON command reports and total verification timing; reports upload on success or failure. No test group or verifier invocation was removed.

The coverage-summary test now owns a private policy revision that requires one coverage attestation, asserts exact before/after summary counts, and checks persisted complete coverage and reviewed-no-change disposition values. Both changed-byte digest outputs are compared against an independently calculated SHA-256. unittest.main() is below OperationVariantTest, so direct invocation includes both variant tests. The generated suite-input refresh affected only the registered digests for docs/plans/README.md and tools/standards_engine/tests/test_coverage_publication.py; producer refresh and non-refresh verification passed 73 suites / 121 checks each before this final test-only assertion strengthening.

Focused evidence on CPython 3.12.9, dependency environment /tmp/cs-a1-profile-env:

Command Result
PYTHONPATH=.:tools/standards_engine/tests:tools/standards_verifier /tmp/cs-a1-profile-env/bin/python -m unittest tools.standards_engine.tests.test_workflow_presentation.SnapshotDetailTests -v 1 passed, 5.778s
PYTHONPATH=.:tools/standards_engine/tests:tools/standards_verifier /tmp/cs-a1-profile-env/bin/python -m unittest tools.standards_engine.tests.test_coverage_publication.EngineAuditPublicationTest -v 1 passed, 37.480s
PYTHONPATH=.:tools/standards_contracts/tests /tmp/cs-a1-profile-env/bin/python tools/standards_contracts/tests/test_compiler.py -v 9 passed, 12.175s, including both OperationVariantTest methods
PYTHONPATH=.:tools/standards_contracts/tests /tmp/cs-a1-profile-env/bin/python -m unittest discover -s tools/standards_contracts/tests -p test_compiler.py -v 9 passed, 11.774s

Controlled negative-oracle probes also passed without modifying source: injecting required_obligations=99 into the summary projection was rejected by the literal 99 != 6 assertion; injecting an incorrect SHA-256 result only for b"changed destination evidence\n" was rejected at failure.observed_digest == expected_observed_digest. These probes demonstrate that the strengthened assertions fail on the intended wrong values.

The workflow implementation worker also reported all three shell blocks pass bash -n, context-placement checks pass, and a 19-case timing harness preserves command/tee status and logs. This report is from the worker; the hosted workflow itself has not run for this candidate. Sol High's final read-only source review found no remaining P1/P2 findings. Both configured Muse/Passeur services report different repositories (Pumas-Library and Tuldok), so no Muse review was submitted against this source. git diff --check passes. The full 13-group suite was not rerun locally, and hosted timing/artifact evidence and maintainer disposition remain outstanding.

Plan status: In Progress. M0 source implementation is present on the isolated candidate; focused CI-A3 evidence is complete, while hosted CI-A1 evidence, full candidate verification, M0 acceptance and performance acceptance remain pending. Exactly one next slice: obtain hosted artifacts for this candidate and disposition the independent review. No commit, push, merge, remote mutation or Library upload was made.

2026-10-22 — retain the plan and reconcile candidate availability

The user authorized committing retained repository work. The earlier temporary checkout /tmp/cs-test-ci-efficiency-m0 is absent, and this repository has no implementation/test-ci-efficiency-m0 branch. The source and diagnostic records above remain historical evidence. Recover the exact candidate before obtaining hosted artifacts or making further implementation claims. This cleanup does not claim the missing candidate was integrated or the CI-efficiency objective accepted.
