hunt-regressions

Review a specific code change and trace its callers to identify behavior that may have broken. Record suspected regressions, reachable triggers, evidence needs, and coverage gaps so a separate reproduction step can investigate them.

Discover candidates

When to Use

Input: sealed preparation, frozen S0/S1, change context and registry assignment. On retry, include this assignment's prior candidate-ID mapping. The caller supplies these, including for independent use. Follow project guidance before target work.

When NOT to Use

Proving a known candidate; use reproduction. Discovery cannot confirm findings.

Hunt

  1. Read the standard and file contract. Verify preparation; read frozen change messages, PR discussion and security documentation for intent and supported use.
  2. Review the entire diff; trace changed behavior through callers to real interfaces. Use frozen sources and supplied context, not later fixes, advisories or other reviews.
  3. Record each lead's changed code, previously supported behavior, reachable trigger, proposed new defect, false-positive checks and required proof. Retain supplied leads suggesting old bugs or incomplete fixes for adjudication. Leave PoC construction to reproduction.
  4. Reserve each lead's ID through registry.py candidate using its stable hypothesis key and assigned agent handle. Reuse the key on retry. Write candidate files and hunt.json with IDs, file mappings, coverage and limitations. An empty list is valid. If blocked, record partial coverage and uninspected areas. Seal the package.

Report Back

Keep detailed evidence in the sealed package. Return only:

  • Status: complete or blocked, matching the record.
  • Record: sealed hunt.json path, or why none was produced.
  • Result: candidate count and material coverage gaps.
  • Blocker: missing prerequisite or required caller action, if blocked.

Rationalizations to Reject

  • “A helper fails on invented input”: show a supported interface that reaches it.
