Sandboxed commands are tagged with an attribution id

Sandboxed commands now carry an id into the sandbox config so activity traces back to its command.

What

Commands run in the sandbox now pass an identifier through to the sandbox wrapper, where it appears as a command id in the macOS and Linux sandbox configuration, so sandbox activity can be traced back to the command that caused it.

Details
  • A new sandbox attribution id option is threaded through the bash and PowerShell exec path into both sandbox wrapper entry points.
  • The macOS sandbox log watcher was reworked to decode its command marker through a caller-supplied resolver, defaulting to identity, instead of a pre-built ignore map.

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