A dead proxy session costs a new session, not three retries
A residential pool sometimes hands out a session that reaches nothing, and it stays dead for every attempt on that token. Mosaic mints a different session instead of retrying the same one, and writes the working one back.

Dead-session rotation, step by step
Notice the dead session
The check before launch finds that the minted session answers but reaches nothing.
Mint another
Instead of retrying the same token, Mosaic mints a fresh session from the provider and checks that one.
Keep what works
The working session is written back to the profile, so the next launch does not start by failing on a dead one again.
The smaller things it does
Only what Mosaic minted
A session id you set by hand is refused with a reason rather than moved, because a pinned session is usually pinned for a reason.
Measured, not assumed
On one pool a dead session stayed dead for every attempt on that token while fresh ones answered, which is why retrying is the wrong cure.
