Stability checkpoint — UI 1.0.51 (CI hygiene wave : 2 fixes confirmed, 2 partial) Captures !120 + !121 + !122 + !123 (UI CI cleanup waves) : ✅ CONFIRMED FIXED on main #2478522873 (this commit) : - grype:scan : /grype absolute path → SUCCESS, shield removed - dockle : svc tarball pattern → SUCCESS, shield removed 🟡 PARTIAL PROGRESS (allow_failure shielded, still fail) : - sonarcloud : heap 4096→8192 + retry runner_system. Still flakes with WebSocket connection closed abnormally. Next escalation : -Dsonar.javascript.workerCount=2 OR scanner image upgrade. - e2e:kind : 4-stage pivot (--wait → pg_isready loop → init-sonar.sql strip). postgres now boots OK (was crashing on init-sonar dir bind-mount). NEW issue surfaced : Spring Boot Flyway 'Connection attempt failed' despite pg_isready green — Docker network connect to compose bridge probably failing silently. Next : add explicit network-connect verification + getent hosts db. Net : 2/4 UI CI debt items fully closed (was 0/4 this morning). 2 remaining items have known root causes documented for next wave.
