What probably matters to youSection of the release
What
Permission code no longer hardcodes a single circuit-breaker name when deciding what cannot be bypassed, and cross-machine isolation denials now survive the bypass path.
Details
A table marks each circuit breaker as bypassImmune / classifierRouted: dangerousRemoval, backgroundOperator, suspiciousWindowsPath, isolatePeerMachines. Previously only dangerousRemoval was checked directly.
The isolatePeerMachines file-transfer denial now stamps circuitBreaker: "isolatePeerMachines" on its decision reason, which makes it bypass-immune in the multi-cd ask path.
The isolatePeerMachines setting still has to be enabled for that breaker to fire at all.
