homing.manual runs two homes. With manual_home_x and _y unset, $H plays no byte and declares X0 Y0 (the checks it had). With 5 and 3, $H declares the head at minus them and jogs it to X0 Y0 before it answers: the sender is told the declared position, the kernel plays the move, Grbl and forgectrl read X0 Y0, and a jog behind the origin draws error:15. The test restores homing_mode and both offsets as found, and returns the head by what the machine read, so a move cut short still comes home. The change stays inside the test's own function. manual_home_test.py: case 7 is the offset's new meaning (declared at minus the offset, the move dark under a modal M3, the port's home, the clamps); a new case cancels the move with a jog cancel and expects it to stop short with $H saying where; case 8 reads the declared position from the sender's message. The bench README says so. Proof: manual_home_test.py ALL PASS against the driver change (ten cases), and its cancel case fails against a build with the driver's cancel hook left out. On the bench reference, fx14 with the driver change and this suite file in place of the image's, homing.manual PASS in campaign c-20260926000059-e731: with no offset no byte and X0 Y0; with 5 and 3 the sender was told X-5.002 Y-3.000, the kernel played 1067 and 640 steps, Grbl and forgectrl read X0 Y0, error:15 behind the origin; settings restored and the baseline clean. The forgetest unit tests pass. Acceptance: homing.manual is the test; its covers are unchanged (the driver's src/**, forgectrl's status and main.c).
