What

Killing an MCP task aborts the drive controller and issues a cancel alongside the main abort, clears the parked state, and waits for the pending write to finish before deleting the helper session and project directory metadata. Less chance of leftover state after a kill.

Details
  • Runs unconditionally for MCP task entries.

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