- The interim cue tables and their opt-outs are gone; the native runtime is the only audio path. Old
settings/audio.json files still load ("interim" / "native" ignored). Missing native data logs an error
instead of falling back.
- Water splash from retail's mechanism (SFXObj_OffBoard start / update): Skate_Collisions 1187 / 1197 once
per water stay, 1198 when the board is in water.
- The random interim riding bed is removed; riding collision and cloth sounds compared with the recomp
(doc 11). Native output otherwise byte-identical (13 scenarios + 5 sessions).
- Published tools under tools/ (one folder per tool with a README; the recomp ones labelled for use with the
research hooks), doc 14 and PR plan bucket L.
- Docs: doc 11 (retirement, bail density measured against the recomp, collision posts), doc 13 (usage guide).

"""Prove a changed stream loader returns exactly what a reference copy returns.

|
|
|
Usage (repo root):
|
|
py -3.13 tools/setup-equivalence/compare_streams.py <reference skate3_streams.py> [District ...] [--work DIR]
|
|
Get a reference with: git show <commit>:tools/vendor/university/tools/vanilla_map_extraction/tools/skate3_streams.py > .local/ref.py
|
|
Needs <work>/<District>/raw (default work .local/collision) from tools/collision-inspect/map_collision.py
|
|
or scan_surfaceless.py.
|
|
|
|
For every district and stream (Pres, Sim, Tex): load with the reference module and the current one, and
|
|
compare every asset's record, source path, source offset, stored size and decoded bytes. Also times both.
|
|
Exit 1 on the first difference.
