Self-reported green

An agent's claim that verification passed, offered in place of evidence. Re-run it. Require per-command exit codes with zero skipped checks, and remember that piped output is not evidence: a pipeline reports the last command's status, so any command followed by <code>tail</code> reads green whenever <code>tail</code> does. This is a bug most teams have shipped at least once, usually in CI, usually for months.
