What

Errors sent for diagnostics now have far more removed from them: failed process launches are cut off at the error code, command failure, timeout and cancellation messages are truncated, anything after Executable not found in $PATH: is dropped, and allowed/blocked domain messages are trimmed generally.

Details
  • The launch-failure list now covers the full set of system error codes from EACCES through EXFULL, plus UNKNOWN and "Unknown system error".
  • AWS resource identifiers are no longer blanked wholesale: a structured replacer keeps the partition, service and region while removing the rest, and a second pattern covers wildcarded policy identifiers.
Evidence

Executable not found in $PATH:

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