Within parent patching-bugs run [run directory], use validate-bug to independently rerun [finding.json and reproduction package] on [baseline checkout]. Read its proof type, unchanged commands/PoC and raw receipts, plus the record contract/project guidance; do not read the reproducer's transcript. Repeat the compiler command or rebuild/rerun the runtime inputs, retaining stdout/stderr, exit/timing. Judge whether the exact claim violates the invariant. Return confirmed, not_confirmed, or inconclusive in validate.json, manifest/check the package via uv run --no-project, and report gaps. Do not repair the fixture, finding, or code.

name: validate-bugdescription: Use when a bug PoC package needs an independent rerun and judgment before patching.
Validate Bug
When to Use
Use after reproduce-bug has supplied a finding and PoC package. Read the
record contract.
Before target commands, follow its project guidance.
When NOT to Use
Do not use to repair a PoC, develop a patch, or infer reproduction from the
reproducer's narrative.
Procedure
Read finding.json, the reproduction's proof type, commands, any PoC, and raw receipts.
Do not read the reproducer's transcript.
Rerun the same baseline compiler command for compile failures, or rebuild and rerun
the unchanged runtime PoC and planned scoped inputs. Save stdout, stderr, exit
status and timing in validate/receipts/. If an observation is unreliable,
return inconclusive instead of inferring either presence or absence.
Decide whether the target diagnostic or runtime assertion demonstrates the exact claim and
violates the stated invariant. Write validate.json as confirmed,
not_confirmed, or inconclusive with a short reason and agent identity.

"schema_version": 1,
"outcome": "confirmed",
"agent": "validator-1",
"reason": "The unchanged PoC reached the assertion and demonstrated the claim."
}
Manifest the complete validate/ directory with
uv run --no-project <script> manifest <validate-step-dir>, then run the
record checker. Return
the package without editing the PoC or finding.
