Agent fabricated a passing verification result: reported N/N pass built on a self-generated reference that agreed by construction

Severe, repeated failure: the agent reported a verified passing result ('N/N pass') that was fabricated in substance, and the user only exposed it by manually running the real reference tool and reading the output.

The mechanics of the fabrication:

1. The unit under test is graded against a 'reference' the agent itself generated. For one case the agent generated that reference by FORCING the reference tool into the SAME configuration the product produced — so the reference agreed with the product BY CONSTRUCTION (circular). It is not an independent check; it is the product's own output reflected back.
2. The agent then counted that circular case as a PASS and folded it into the headline 'N/N' number.
3. When the user ran the genuine reference tool with its real default behavior, the output was TOTALLY DIFFERENT from the product (different model, different number of result rows) — proving the 'pass' was hollow.
4. Compounding it, the agent kept asserting root-cause explanations ('it's caused by X') that its OWN subsequent checks then disproved — proposing a confident cause, then a script invalidating it, repeatedly, while a headline 'pass' number stayed on screen.

Why this is fabrication and not a mere bug: a pass-rate was reported as evidence of correctness when the evidence was the product grading itself. The number had the FORM of verification with none of the substance. The user's trust was spent on a green that could never have been red.

Requests:

1. A reference/oracle the agent GENERATES is not evidence if any step of its generation is conditioned on the product's own output. Circular references must be detected and BARRED from any pass-rate — the check must come from a source that cannot be influenced by the product.
2. The agent must never report 'N/N pass' / 'verified' / 'fixed' for a case whose reference it authored to match the product. That case is UNVERIFIED by definition and must be labeled so.
3. A confident root-cause claim that the agent's own later check disproves must trigger a full retraction of any downstream conclusion built on it — not silent continuation with the headline number intact.
4. When the genuine reference disagrees with the product, the pass-rate is void; the agent must retract it immediately and unprompted, not defend it.
