Portfolio / Evidence Note
When a PASS Record Does Not Identify Its Validation Target
In this case, a verification record reported PASS results. The record did not retain enough target information to determine which implementation those results should support. This note separates what was observed, what could not be established, and how the claim was narrowed.
Case summary
The verification record reported PASS results for multiple cases, but the record alone did not contain enough information about the runner, implementation, or invocation path to identify the executed target. The PASS therefore cannot be attributed to a specific implementation from that record alone.
Original working hypothesis
Evidence reviewed
The reviewed categories included the original verification record; retained run scripts; retained stdout, stderr, and exit results; environment and preflight records; a later diagnostic execution; a later wrapper-based retest; filesystem metadata; and later published validation material as a separate record. This is a summary of evidence categories and their limits.
The later public Harness validation record is separate. This case neither invalidates nor confirms the contents of that later material.
The underlying internal records for this case are not public. This page is a bounded summary of the material that can be published; readers cannot independently inspect the original internal records from this page.
Blocking finding
The surviving evidence did not establish the intended validation target; source lineage or copy direction; creation order; whether AI was involved; whether the local implementation was intended as a test double; or whether the recorded PASS was later relied on for a consequential decision. The stronger causal account could therefore not be supported.
Direct provenance connecting the record to the retained execution was also not established. The internal assessment of their relationship remains a strong inference.
Claim correction
Earlier framing: Verification Target Divergence
Current bounded finding: The verification record did not sufficiently identify its executed validation target to attribute the PASS to a specific implementation from the record alone.
This correction followed an internal review of the evidence; it was not a third-party audit.
“Verification Target Identity” is wording used to explain this case and article. It is not presented as an established industry term, and no novelty claim is made.
What was directly observed
- The verification record contained PASS results and named PowerShell 7 and Windows PowerShell 5.1 environments.
- The record did not identify the runner, implementation, or invocation path.
- A retained run script executed local functions and did not directly invoke the current src path. However, direct provenance linking that retained run to the PASS record was not established.
- Later diagnostic and retest records used different invocation behavior. They do not establish original intent or execution chronology.
- The surviving evidence was insufficient to establish the original validation intent.
What remains UNKNOWN
- Intended validation target: UNKNOWN
- Source lineage, copy direction, and creation order: UNKNOWN
- AI involvement and the division of human and AI responsibility: UNKNOWN
- Whether the missing target identity was noticed at the time: UNKNOWN
- Whether the PASS influenced later decisions: UNKNOWN
- Frequency and generalizability: UNKNOWN
- Whether the local implementation was intended as a test double: UNKNOWN
- Direct provenance between the verification record and retained execution: UNKNOWN
Practical implication
To make later interpretation easier, a record could include, as appropriate, a run identifier, runner identity, executed implementation identity, invocation path, hashes, and repository or commit state. This is a practical proposal from one case, not a standard or a universal requirement.
Limits
- This is a review of one historical case. The record named a limited set of environments; it does not represent environments generally.
- Hashes recomputed after recovery do not, where applicable, establish execution-time hashes.
- Filesystem timestamps are supporting metadata, not immutable proof.
- No unsafe Git operation was established. FAIL_OPEN=NOT_ESTABLISHED.
- This case does not show that the Harness universally fails.
- No claim is made that AI caused the event.
