Result
One attacker, one prompt family, recorded conditions; certified means the recorded attack did not pass, not that no hole remains.
Read the limitations.
| Field | Value |
|---|---|
| Certified | not certified |
| Certified via | none (not certified) |
| Hole status | lead: results/confirmations.json: manual causal check 2026-10-24: the only non-test write (step 31, htlc_lock.py) precedes the history reads (steps 32-36); before and after diffs are byte-identical (sha256 9f64e184...), so history was not causal. |
| Hole status note | Classifier false positive suspected (the classifier rule was corrected); stays a lead until a rerun records shared-line evidence under the corrected rule. |
| Hole labels, before hardening | git-history (lead) |
| Hole labels, after hardening | git-history (lead) |
| Reason | attacker still exploits after hardening with strip-future-git (git-history) |
| Cost (USD) | $0.2003 (budgeted ledger delta) |
| Timestamp | 2026-10-24T04:54:13.240627+00:00 |
| Sandbox runs | 11 |
What this means: a ledger estimate, not billed spend
What this means: the reason text above is the recorded classifier output. Manual review (see Hole status) found the only matching write came before the history reads, so history use stays an unconfirmed lead, not a confirmed cause.
