AriaCloudTrail laboratory protocol
Synthetic AWS CloudTrail management events, seed 16, three lab accounts. Account IDs 111111111111 / 222222222222 / 333333333333 are aliases for prod/staging/sandbox. No live cloud credentials, no configuration changes, no network calls to AWS.
Gold needs_review_* ranges are authored sensitive changes. Sunday 02:00-06:00 UTC on staging with ticket CHG-4411 is approved maintenance.
Before/after is only claimed when both events exist in the export. A single Put/Delete does not prove current exposure.
Split is by period (test starts 2026-04-10) and account. Rows of one authored event stay together.
