cadence census checklist: night-17 queue closed out -- five rows moved to DONE with bench numbers (sway inherited 4.5x, gyro timescale-only impulse verdict, footstep ramp90 restored, doppler -20% operand TV with T3 perceptual flag, registry map pattern); new rows: child-entity worldLinearVelocity=0 self-sound doppler (pre-existing, needs a binary-behavior ruling) + the five-clock BTSimClock consolidation note. decomp-reference env-gate table gains BT_GYRO_SPRING_HZ / BT_GYRO_KICK / BT_AUD_SMOOTH_HZ / BT_AUD_DOPPLER_HZ / BT_AUD_DOPPLER_LOG.

+DONE (each a per-instance 28Hz accumulator/hold, heat.cpp #119 pattern, env-override to
+bracket, receipts armed):
+- velocity ring default-28Hz (mech4.cpp, HIGH, the #173 fix -- myomer heat inherits);
+  heatLoad already pod-clocked (#119, the reference pattern).
+- instability/sway operand: VERIFIED inherited from the ring fix (no code change) -- same-
+  build A/B via BT_MYO_RING_HZ=0: cruise unstablePct median 0.490 -> 0.109 (4.5x), |a| p90
+  48 -> 14.5.  [T2]
+- gyro eye/body spring-damper integrators (gyro.cpp, was MED): stepped on a 28Hz
+  accumulator, integrator bodies byte-untouched; impulse bench (BT_GYRO_KICK one-shot)
+  BEFORE/AFTER: overshoot 23%->7%, period 1.43->2.4s, settle equal (per-SECOND damping is
+  cadence-invariant); shape verdict = timescale-only.  BT_GYRO_SPRING_HZ.  [T2]
+- footstep AudioControlSmoother intake (AUDCMP.cpp, was LOW): only the Add clocked; the
+  poll path measured at ~141-147/s (worse than assumed -- the wall window was 0.2s, not
+  0.5s); ramp90 0.55->1.23s (the authored ~1.07s window restored); N untouched.
+  BT_AUD_SMOOTH_HZ.  [T2]
+- doppler operand (AUDLOC.cpp, was LOW): relative WORLD velocity sample-and-held at 28Hz,
+  consumer-side only, head-frame geometry live; operand total-variation -20%, stride std
+  preserved.  BT_AUD_DOPPLER_HZ + [doppler] receipt (BT_AUD_DOPPLER_LOG).  [T2 mechanism /
+  T3 PERCEPTUAL -- solo-rig cents jitter moved only -11% (near-field geometry dominates at
+  d~1); the nearby-walking-mech warble claim still needs an ear A/B or a 2-node rig.]
+- ring dt-accumulator registry productionized: 16-slot static -> heat.cpp map pattern
+  (17th-mech silent revert now impossible); smoke identical within run noise.  [T2]
+
+REMAINING for the BTSimClock migration (one shared 28Hz tick source; tick-native sites
+subscribe; dt-native physics -- Mover/missile ODE -- stays on real dt):
 - LOW published localVelocity 0.25s exponential smoothing (mech4.cpp:5578-5613): re-base to
   the binary's own 15-sample@28Hz filter once the shared clock exists.
+- NEW (night-17, receipt-exposed, pre-existing, UNTOUCHED): doppler sources linked to CHILD
+  entities of a moving mech read relative v = full ground speed (child worldLinearVelocity
+  = 0) -> dopplerCents ~ -200 on self-sounds at d~1 (the [doppler] receipt shows it
+  directly).  Not a cadence bug -- a producer-frame question; determine whether the
+  binary's located-audio path behaved the same (the pod cab may simply have masked it)
+  before touching anything.  [T3]
 - DEFERRED dead-reckon divergence (@_DAT_004be050) -- only matters if the Missile entity
   revives.  ANNOTATE-ONLY: Simulate telemetry FilteredScalars (dormant).
-- Productionize the ring's 16-slot dt-accumulator registry (mech4.cpp) to the heat.cpp map
-  pattern (degrades gracefully to per-frame push on overflow today; fine for one mission's
-  mech count, sloppy long-term).
+- Consolidation: five per-site clocks now duplicate the same accumulator idiom (heat, ring,
+  gyro, smoother intake, doppler hold) -- fold onto the one BTSimClock when it lands, one
+  site per commit, using the existing env-overrides as the bracketing levers.
