+- **"Too fast to be a walk"** — both levers pulled: `Character_Default.asset` **MoveSpeed 6 → 4.2** (near the run clip's natural pace; enemy chase default is 3.5 so kiting margin tightens 2.5→0.7 u/s — deliberate, heavier game; revisit if it frustrates) AND a **two-ring gait tree**: the Locomotion FreeformDirectional2D now holds idle center + a **WALK ring @0.35** (= walk natural 1.46 / MoveSpeed) + a **RUN ring @1.0** (17 children). MoveX/MoveZ magnitude = speed fraction, so the underwater accel ramps walk→run automatically — "walk first, run when held". Verified live: MoveZ 0.50→1.00 over the ramp. **The walk-phase duration = the `Move sharp` overlay knob** (lower sharpness = longer walk-in).
+- **StrideScale recalibrated** to the walk→run **blended natural** (`StrideScaleValue`: lerp 1.46→2.6 by ring position; clamp 0.6–2.2) — now a fine correction (live: 1.09→1.37) instead of the old 2.75× crank. `FeelConfig.RunNaturalSpeed` = 2.6 measured.
+- **The shoulder lamp CASTS**: a warm-gold STEADY spot (`~ShoulderLamp`, client-only) mounted at the kit lamp's clavicle offset, riding the **body yaw** (bolted to the suit — sweeps with the body, not the cursor), down-tilted 26° so the hotspot pools ~3m ahead. Intensity 8 / range 12 (`FeelConfig.ShoulderLamp*`; 3 got lost in the murk ambient; 14° tilt landed ~6m out — too diffuse). Verified: a clear warm pool on the seabed ahead of the diver.
+- Play validated: gait ramp live-sampled, lamp beam screenshot (`lamp_beam_final.png`), 411/411 green. NOTE: a mid-Play recompile left a ghost play session with zero ECS worlds — stop+replay cleanly rather than trusting a play-restart after script changes.

 ## Next session
 
 Operator eyes-on feel pass with the live knobs (turn rates, sharpness, footstep values), then pick from the gap list (recommend 1+3 first). Post-impl review findings (wf_9a8d6162-e72) to triage if any confirmed.
