Reviews: audit run 2 record — QuantEcon/meta, resumability validated - #56
Merged
Conversation
Second run in the #16 validation program, and the first to test the claim the program exists to check: an interrupted run resuming across a lost session. It resumed at the predicted item with no re-walk, no skip and no duplicates. Two claims move from asserted to measured. Read-only is verified by a before/after fingerprint of all 317 issues rather than asserted. The open-count scaling conclusion gains a second data point. The principal method finding is invisible in the bundle and came from observing the run externally: the closed pass is not incrementally checkpointed — one write for 179 items against 15+ for 138 open — so SKILL.md's "loses one item rather than the phase" does not hold there. That is run 1's defect 2 in a new form, the 0.2.0 fix having addressed the format and not the granularity. Two candidate findings were investigated and discarded; both are recorded with their reasons, so the report shows its own false positive rate. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Pull request overview
Adds the second validation-run record for /qe:audit-issues (run 2) against QuantEcon/meta dated 2026-08-25, capturing measured evidence for resumability across a killed session plus additional operational observations from external sampling.
Changes:
- Add a new run record documenting snapshot provenance, measured runtime/cost, interruption/resume behavior, and read-only verification.
- Record a key method finding: the closed-pass portion is not incrementally checkpointed (plus follow-up recommendations).

…ding Copilot's review of #56 caught two things. Quoted guarantees pointed at a bare "SKILL.md" with no repo, path or version, so they would stop resolving the moment the skill changed — the same class of defect run 1 was faulted for, one level up. All six references now point at the tag whose tree this run actually executed. And "the working tree was unchanged" sat next to a git status showing ?? .audit/, which reads as a contradiction. It now says no tracked file changed, with the untracked output directory named as expected. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The record for run 2 of the
/qe:audit-issuesvalidation program, againstQuantEcon/metaon 2026-08-25. Repo-level file only, so no plugin version bump is due.The headline: resumability held. The run was deliberately interrupted at 68 of 138 open issues, the session was killed, and a fresh session resumed at
#261— the exact item predicted and recorded before the resume happened. No re-walking of completed work, no skipping the item it died on, no duplicate entries, and the pre-kill bytes were identical afterwards. That is the claim the whole program exists to falsify, unfalsified at last; run 1 never attempted it.Two claims move from asserted to measured. Read-only is now verified by a before/after fingerprint of all 317 issues (state,
updated_at, comment count, labels) diffing to nothing, rather than asserted as run 1 did. And the "what scales is the open-issue count" conclusion gains a second data point: 2.5× the open issues, ~2.4× the elapsed time.The principal method finding is invisible in the finished bundle. A second session observed the run from outside, sampling
findings.mdevery 15–20 seconds. That showed the closed pass is not incrementally checkpointed — one write covering 179 items, against 15+ writes for the 138 open ones — so SKILL.md's guarantee that "an interrupted run loses one item rather than the phase" does not hold on the closed side. This is run 1's defect 2 in a new form:audit0.2.0 fixed the format by adding the## Closedheading and the two-partition resume rule, and left the granularity untouched. There is a second-order problem too, sincedeliverables.mdpermits grouped entries while the resume rule addresses by issue number, so the two conventions do not compose.Two candidate findings were investigated and discarded, and are recorded with their reasoning rather than quietly dropped — an out-of-order-write hazard that rested on inferring an algorithm from a status message, and a batching claim that dissolved into a bounded measurement once sampled. A validation report that lists only confirmed findings hides its own false positive rate, and the discipline that killed them is the same one run 1's severity-1 defect failed.
Six follow-ups are proposed in §8 for filing as their own issues, per the plan convention. §9 lists what only you can answer: whether the tiering matches how the repo is actually planned, whether the 19 drafted closing comments are ones you would send, and where the bundle should live given it contains AWS and access-token findings.
