Root cause: Seed-data masks defaults. SC1 roundtrip probe used Time=09:00 — safe in both 12h and 24h formats. The 24h→12h conversion bug only fires for values ≥13:00. Morning seed value masked the defect entirely.
Proposed amendment (skills/tester-mindset-forms/SKILL.md):
Time-format boundary probe — When a form contains a time picker or dropdown, the roundtrip MUST exercise at least one value ≥ 13:00. Morning values (00:00–12:00) are safe in both formats and will not detect 24h→12h conversion bugs.
Root cause: Absence-of-feature blind spot. Restore charter probed upload safety (R3 MIME, R4 zip-slip) but never constructed the critical boundary artifact: a valid zip with a truncated SQL file that causes DROP TABLE to fire without the subsequent CREATE TABLE completing.
Proposed amendment (skills/tester-mindset-andlist-destructive/SKILL.md):
b5 — Import atomicity / partial-failure state — For any operation that issues destructive SQL (
DROP TABLE,DELETE FROM,TRUNCATE) as part of an import, probe the partial-failure boundary: craft a structurally valid but truncated input. Verify the system state after failure — original data intact (transaction-wrapped), or clear recovery path.
Both miss classes are first occurrences.
2 high-severity gaps, 4 low-severity gaps — one supplementary Tester dispatched, closing both high-severity gaps:
| Gap | Severity | Resolution |
|---|---|---|
| SC2 vs a5 contradiction: cron registers before or after Enable+Save? | HIGH | Supplementary tester confirmed: cron always registers on activation |
SC1 missing magellan_* prefix search (Pilot 18 miss class) |
HIGH | Supplementary tester found real bug: email key mismatch → P13 |
| Toggle-state-leak probe silently dropped | LOW | Noted, not re-dispatched |
| Uninstall path not probed | LOW | Noted, not re-dispatched |
| Export tab missing from mode-toggle surface tour | LOW | Noted |
| Coverage-note literal format non-compliance (paraphrased strings) | LOW | Amendment proposed for future runs |
- Issue 9 (OOM / unbounded SELECT) caught independently by two sessions (
backup-artifact-andlista7 +selective-export-artifact-clusterSE4), confirming the c2 scale-pattern rule fires across code surfaces. - Email key mismatch (Issue 3) found only because the supplementary Tester explicitly searched the
magellan_*prefix — the initial wave's SC1 probe only confirmedmb_*keys. This was the Pilot 18 miss class; meta-review caught the gap. - Recon S1 (backup creation broken) was environment-specific on the recon site;
backup-artifact-andliston a fresh instance proved backup creation works — demonstrating the value of per-charter site isolation. - Delete flow (0 problems) — nonce validation, path-traversal sanitization, and capability checks all passed empirically. Clean surface.
