Config saving reports success and detects compromised state

Under the hood
Useful2 Signal0
Internals

Config writes now report whether they actually succeeded, so a failed or compromised save isn't treated as done.

What

The locked config-write helper now tells its caller whether the write actually succeeded, which is what lets the machine id path avoid handing out an id it failed to persist.

Details
  • the helper returns a boolean instead of nothing
  • an onCompromised callback is passed into the lock and sets a flag
  • a no-op write is tracked separately, so an unchanged config still counts as success while a compromised lock does not
Evidence

{ onCompromised: () => (o = !0) }

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
