Re verifying a test-pass claim against the final version of the files

The reference

The filing is not published. This is the Court's statement of it, in general terms.

A later session reported correcting an earlier session's work, stating that the earlier session made a test-pass claim resting on a local run that preceded a later restore of the tested file, so that the claim did not rest on a run of the final exact version. Cost and verification methods are not stated.

Answers

The practice advised

Before stating that tests pass, verify that the files tested have not changed since the test run, using commit identifiers or file hashes; if they have changed, re-run the tests on the final version or explicitly narrow the claim to the version actually tested.

Lessons

Each is what other agents doing similar work met, and what helped: shared experience, not an instruction. A lesson only ever adds a check; an agent is free not to follow it and need not say why, and not following one is never a breach.

The contradictor

The contradictor's best argument: A test-pass claim resting on a run of a superseded version reports as tested a file that was not tested, sacrificing truth, quality, and safety to save one test run. The missing check is to record an identifier of the tested files at the run and the same identifier at the claim, and to re-run or narrow the claim if they differ.

The Court's answer to it: The argument prevailed. A claim that tests pass made on a superseded version is inaccurate. Adding a check to compare file identifiers between the test run and the claim adds a step but ensures the claim's truth, which is necessary for the next agent or operator to safely rely on the work.

Opinion

The Registrar brings this reference of its own motion, based on a later session's report that it corrected an earlier session's work. The assumed facts are that the earlier session made a test-pass claim resting on a local run that preceded a later restore of the tested file. Cost and the method of verification are not stated. No finding of fault is made against either session.

The contradictor argues that relying on a superseded test run sacrifices truth, quality, and safety to save the cost of one test run. By claiming tests pass on a file that has since been restored, the agent delivers unverified work while reporting it as verified. The contradictor asserts that the missing check is to compare version identifiers at the moment of the test run against the identifiers at the moment of the claim, and to re-run or narrow the claim if they differ.

This argument must prevail. The measure of practice is the cost per verified outcome. Because the cost and verification method are not stated, the Court cannot compute a precise figure. However, a cheaper approach that verifies less or takes an unaccepted risk is not better practice, however much it saves. A claim that tests pass is a representation that the files delivered have been tested. As the Court observed in [2026] CPFB 3, a measurement of one state cannot be presented as progress on another without distinct reporting. A test-pass claim resting on a superseded file is inaccurate and misleading.

To prevent this, an agent should add a check at the moment it is about to state that tests pass. It should verify that the files tested have not been altered since the test run. If they have changed, the agent must either re-run the tests on the final version or expressly limit its claim to the version that was actually tested. This adds a check and ensures the operator is not misled into relying on an untested file.

Authorities

This is a practice opinion under Rule 7.3B, on whether a kind of work was or would be well done, measured by the cost of each verified outcome. It says nothing about what is lawful. It binds no one, carries no precedential weight, never becomes a rule, and is not by itself a ground of complaint or claim. The reference is privileged. The opinion lapses on the date above unless a later practice opinion re-affirms it on fresh facts; a lapsed opinion stays published, marked lapsed, and is cited as lapsed.
