# Low-speed turn-intent curvature hold. Approaching a turn with the blinker on, the
# model's time-based plan collapses as the car slows to a stop: desiredCurvature decays
# to zero, the controller actively unwinds the wheel at the intersection, and on
# pull-away it re-winds too late — the car goes wide (pauseturn rlog 2026-07-13).
# The hold ratchets up on the blinker-matching model command below the release speed
# and floors the command magnitude afterwards. Below the hard speed the floor is firm;
# between hard and release speed it decays toward the model's sustained demand, so a
# transient model dip barely sags it while a genuine end-of-turn unwind or an aborted
# turn still drains it in a few seconds. Retention deliberately does NOT depend on the
# blinker (the stalk auto-cancels during the stop in the log), on latActive (lateral
# goes inactive at standstill on torque cars; the wheel parks on rack friction), or on
# steeringPressed (the driver's instinctive grip during the unwind is what let the
# collapse through, and the driver physically overpowers a torque command regardless).

# floor mid-turn and visibly unwound the wheel 50 deg before the action woke; rights
# wake at ~2.2 m/s and never showed it). Hold authority above creep speed is bounded
# by the opposite-command release and the decay band, not by this ceiling.
CURVATURE_HOLD_RELEASE_SPEED = 10.0 * CV.MPH_TO_MS
# Pre-wind stays a low-speed device: the plan-geometry source only feeds the ratchet
# below this speed; above it only the model's own action can raise the hold, and only
# at a limited rate so a single-frame action spike (left1 rlog 21.9s: -0.157 for one
# model frame) can't get captured and floored for seconds.

# The model's time-domain action.desiredCurvature is blind below ~2.5 m/s (0.3 s ahead
# at creep speed is centimeters of road), but the plan's spatial geometry already shows
# the turn at standstill: turn3/turn4 rlogs 2026-07-14 read plan curvature 0.13-0.16
# while the action output sat at 0.005, and the plan value matched the demand the
# action produced once rolling. Feeding it into the turn-hold ratchet lets the wheel
# pre-wind toward the real turn before the car moves. Scaled and capped conservatively:
# a too-high floor turns in tighter than the path (mild at creep lat accel), while a
# too-low one just reduces the head start. The plan flickers straight for ~1-2 s right
# at the standstill->motion transition; the ratchet holds through it by design.
