W5 Managed Provider Canary Main Trigger

Purpose: Dispatch the reviewed W5 IAM-private synthetic provider canary from trusted main against this exact merged source.

Scope: Evidence trigger only. No application, Android, backend, workflow or infrastructure implementation change.

The trusted main trigger must dispatch the reviewed W5 managed canary, preserve synthetic-only data and private IAM, remove temporary Invoker grants, and must not activate real participants, public cutover, real payment movement or formal Phase 12 production release.
