 Nine regression scenarios pass. Original helper fails8/9 with exit1; empty-origin control passes. Ten deliberately broken variants exit1 and were restored: overwrite existing rules; reverse rules; omit dedup; repeat PUT; include covered origins; reject absent policy; swallow read errors; empty-origins IO; ignore non-origin permissions (kills scenario5); remove SDK GetBucketCors export. Every scenario fails under at least one variant. Final focused runner passes3/3 files (13 scenarios total:9 CORS,3 cache-control,1 empty upload).
 
 `npm ci --offline --ignore-scripts`: exit0,441 installed packages in4s from local cache. Initial lint exit127 absent stylelint; after install lint exit2 sandbox EPERM read-only git subprocess. Unchanged lint with sandbox permission exits0,11 checks. `npm run build`: exit0 incl dist artifact verification. No dependency file changes. Normal full-suite/landing slot reserved after client; awaiting explicit grant. Cloud IAM permissions, actual provider response serialization, concurrent read-modify-write races, browser/live playback remain unverified. Read-modify-write has no provider CAS guarantee and concurrent writers can still race.
