A gated setup flow lets users choose an @muse.ai address for their agent, but the client inspection cannot show whether Meta will enable it at Connect.

RUNTIMEWIRE INVESTIGATION — Original analysis
Original reporting by RuntimeWire, based on reverse engineering.
Why it matters
An @muse.ai mailbox would let people address a Muse agent directly. The Mac client shows the intended flow, while live availability and the controls on incoming mail remain untested.
Reporting record
Finding
A static inspection of Muse 2.2 found a flag-gated client flow for creating an agent-owned @muse.ai mailbox, but did not establish that the service is live.
How we verified
Methods: reverse engineering.
The supplied Muse-2.2.dmg (SHA-256: 3db5892d1a2eed700554083edfa0c09daf1c8872ffd919c8117725a3722eec49) contains a Mail feature flag, CreateMailboxSection, @muse.ai address suffix, and mailbox and message requests in Muse.app/Contents/Resources/hatch/index.html.
RuntimeWire statically inspected the user-supplied Mac installer, checked its Info.plist for the version and build, and examined the packaged client code for the mailbox setup flow and requests. It did not test an authenticated account or live server.
Tested versions: Muse 2.2, build 1074644564 (production channel; statically inspected).

Company response
The company was not contacted before publication.

A static inspection of a Muse 2.2 installer supplied for review found a gated address-creation flow and a mailbox with Received and Sent views. It did not establish that the service is live or that Meta plans to announce it at Connect.…
