With icarus-cloud merged, main is the one branch. Deploy Web now runs on
pushes to main (and refuses any other ref), CI no longer watches
icarus-cloud, and the contract gate records its merge base with
origin/main, so it keeps working once icarus-cloud is gone.

The release doc says so, and the typed-wrapper ADR no longer reads as
if clearing an outbox were acceptable: cloud has had real users since
2026-09-27.
