# NEXT11 V6.33 R9 — ATG dual-plant rise + rear-foot step-through

## Base / package policy
Apply this single consolidated delta on top of the locked V6.32 fullroot:
`NEXT11_V6_32_DYNAMIC_WARMUP_18_OF_18_BUGFIXES_LOCKED_FULL_ROOT_LIBRARY_READY.zip`

This package physically carries the cumulative V6.33 R2→R9 chain. Separate R2/R3/R4/R5/R6/R7/R8 packages are not required.

## User-approved R9 ATG authority
R9 supersedes the R7/R8 ATG rise mechanics while preserving the R8 camera authority.

ATG sequence is now:
1. lead/front foot steps forward and plants,
2. descend into lunge,
3. from bottom through the complete rise BOTH feet remain planted,
4. brief upright split-stance hold,
5. only then the rear foot releases and steps forward,
6. front foot remains the station/authority through the rear-foot step-through.

Resolved authority:
`assets/nexprod/resolved/atg-split-squat-lunges-v633-r9-dual-plant-rear-step.resolved.json`

The persistent-player asset map was explicitly updated to R9. This is important: earlier testing showed that the persistent player has its own resolved-asset map and can otherwise continue loading an older ATG asset even when the travel profile points at a newer authority.

## Camera authority preserved from R8
- `cameraLeadResolvedRootXZ = false` for ATG.
- Camera X is fixed relative to the runway lane.
- Camera Y and look-at Y stay fixed.
- Camera Z follows only continuous outer world/runway travel.
- Internal ATG resolved-root motion does not drive the camera.

## QA
### Simple motion QA (no passplayer/UI)
- `qa/V6_33_R9_ATG_DUAL_PLANT_REAR_STEP_SIMPLE_QA_REFRAMED.mp4`
- `qa/V6_33_R9_ATG_DUAL_PLANT_REAR_STEP_SIDE_KEYPOSES_REFRAMED.jpg`
- `qa/V6_33_R9_DUAL_PLANT_SIMPLE_AUDIT.json`

Resolved-space first-repetition audit during rise:
- front-foot drift: ~0.00007 mm
- rear-foot drift: ~0.00003 mm
- front foot remains planted through rear-foot step-through

### Real Chromium passplayer QA
Route: `preview.html?workout=dynamic-warmup#pass`, exercise 7/18.

- `qa/V6_33_R9_ATG_REAL_PASSPLAYER_QA_REALTIME.mp4`
- `qa/V6_33_R9_ATG_REAL_PASSPLAYER_CONTACT_SHEET_CHRONO.jpg`
- `qa/V6_33_R9_RUNTIME_CONTINUOUS_AUDIT_V2.json`

User reviewed the real passplayer QA and approved packaging (`"Tror det funkar ta och paketera"`).

## Preserved cumulative fixes
- R2 lunge/transition work
- R3 reverse-lunge rear-foot authority / Hurdle entry work
- R4 Hurdle structural-head authority
- R5 fixed vertical camera authority
- R6 consolidation
- R7/R8 ATG presentation/camera work where still applicable
- R8 camera world authority
- R9 ATG dual-plant rise + rear-foot step-through

## Status
Packaged consolidated checkpoint; user visually accepted R9 ATG for packaging. This is not promoted to a new locked fullroot milestone.
