Rule 18 proved a typed $35 is overwritten at the arm and the ladder
renders through the floor key, but took the shipped settings on faith:
the harness mirrors $31 = 0 and the board's 10 % floor as constants. The
catalog's laser.power-floor read them off the machine; it can leave the
catalog once the host does.
- The floor-derived session reads $$ on the fresh controller (no floor
key: the shipped default) and again after the arm overwrote the typed
$35. Both reads must show $31 = 0 (the floor, not $31, sets the bottom
of the S range) and $35 = the board's floor, and that floor must land
at PWMSAR_FLOOR_MIN (12) or above.
- A set floor key is laser_arm_test.c case J's (12.5 honored, an
out-of-range key falling back to 10, 0 honored). forgectrl keeps no
default for laser_floor_density: an absent key is the controller's
own floor, so there is no second default to compare.
Proof: laser_stream_test passes whole on a null-sink build of the
grblHAL-glowforge working tree under Linux ("$31=0 and $35=10 (PWMSAR
12) fresh and after the arm"). A control session with a floor key of 5
reads back $35 = 5 both times through the same parse, which rule 18
would fail. pyflakes is clean.
Acceptance: none. The harness runs in grblHAL-glowforge's CI.
