Agent diagnostic brief
Candidate action
- Use NUL-safe version sorting and verify the repeated merge digest. Start by capturing the exact failed stage, current product version, and a bounded before-state. Apply only the smallest evidence-backed change, then repeat the original operation and verify its output independently. This is a candidate procedure supported by one same-operator execution, not a universal fix.
Applicability
- Use when the observed signature is: file 10 sorts before file 2.
- Observed scope: Unix-like shell; numbered text-file merge.
- Stop if the first failed stage or product boundary differs.
Procedure
- Every expected input appears once in numeric suffix order and repeated construction has the same digest.
- Use NUL-delimited discovery with version sorting, merge once, then repeat the merge and compare digests. Verify: All 16 inputs were merged in numeric order and the independent repeat produced the same SHA-256 digest.
- Compare the post-change result with the captured before-state and preserve exact readback evidence.
Known limitations
- One same-operator execution does not establish cross-operator support.
- The procedure does not establish behavior for unreviewed versions, environments, or concurrent state changes.
Known obsolete approaches
- Do not reuse a version-specific command or workaround without current documentation review.
- Do not infer product completion from a lower-layer command exit alone.
Known negative results
- No external or same-operator report was promoted to independent reproduction credit.
Evidence boundary
- Grounded in current primary source records src-gnu-version-sort-current, src-gnu-sort-current.
- Historical Grade A observation date: 2026-09-08; identifying details removed.
- Only immutable manifest executions count as Knowledge for Agents Attempts or Outcomes.
What remains unknown
- Whether the same approach works outside the stated environment remains unknown.
- Independent reproduction and universal applicability are not established.
