Aura3D 4.7.2

Superseded. This version is deprecated. Upgrade to Aura3D 4.7.5.

GameUpgrades47 phase 4 (docs/prds/game-upgrades-47/GameUpgrades47-PRD.md; lane reports in docs/prds/game-upgrades-47/lanes/, "Phase 4 (4.7.2)" sections). Every game was retuned for shadows, reflections, lighting and identity against its genre neighbours. A changed view ships only where a blind three-judge panel still preferred it to the 4.6.2 frame of the same view; every other view opens exactly as in 4.7.1. Gameplay, rules, determinism and the reference replays are unchanged. All visual numbers are software WebGL2 on the remote runner.

Games

• Distinctness (model judge, aura3d evidence judge --mode sibling, 48 trials, needs same_game: false at confidence 0.8 or more):

  • Passes against every genre neighbour: Chroma Roll, Lamplight Line, Duneglide, Aura Slam 3D, Iron Crown, The Bellkeeper's Walk, Grid Dispatch, Gridlock Courier, Aura FC 3D, Aura Links 3D, Bunker Zero, Slingshot Siege.

  • Some pairs still fail:

    Game	Failing neighbours	Why the judges match them
    Ion Circuit	Thermal Drift, Saltwind Highway, Craterline GP
    Saltwind Highway	Apex Overdrive, Ion Circuit
    Serpentine Sky Run	Shadowstep Gauntlet, Cumulus Dash
    Shadowstep Gauntlet	Cumulus Dash
    Aura Hoops 3D	Aura Diamond 3D, Aura FC 3D	shared athlete models
    Aura Diamond 3D	its sports neighbours	shared athlete models
    Cross Hop	Pip's Big Leap	glossy figurine heroes
    Pip's Big Leap	Cumulus Dash (0.794)

• Shadows and reflections:

  • Contact shadows, tighter shadowed keys and glossier floors, vehicles and walls where the panel kept them (Thermal Drift, Duneglide, Slingshot Siege and others).
  • Shadow probes (tests/browser/gu47/*-shadow-probe.spec.ts) record which casters sample on software WebGL2.
  • The luma capture now also logs the shadow and quality diagnostics.

• WP-36 Meshy assets already generated are swapped in (presentation only, geometry inside the existing bounds):

  Game	Asset swapped in
  Apex Overdrive	cobalt hero retexture
  Grid Dispatch	pearl player pod
  Iron Crown	forge brazier
  Aura Hoops 3D	Rucker floodlight
  Aura Diamond 3D	seated fan
  Aura FC 3D	stand module (replaces the borrowed stadium)
  Aura Links 3D	marram grass
  Bunker Zero	blast doors
  Slingshot Siege	sea-stack islet
  Glint Courier	courier pod
  Cross Hop	coin
  Chroma Roll	paint-pot island
  Serpentine Sky Run	serpent head
  Ion Circuit	sentry drone
  Shadowstep Gauntlet	dusk house
  Lamplight Line	enamel tram
  The Bellkeeper's Walk	paper kite (replaces the wisp)

  • Gridlock Courier's teal retexture was reverted: it painted blotches on the rear hatch.
  • Craterline GP's rider failed its geometry check and is not used.

Known limits

• Rubric below the PRD bar. No game scores 7 or more in all 12 categories (model judge, software WebGL2). The HUD reaches 7 in several games. Reflections and shadows stay lowest, from 2.5 to 4.5. Lanes found that glossy floors and screen-space reflections barely show in the software-rendered captures; a real-GPU judgement (owner-run, PRD D5) is needed to tell a capture limit from a look limit.
• WP-36 Meshy batch blocked. 641 of 669 remaining rows are blocked: every Meshy key that reports a balance answers paid API calls with HTTP 402, so no new asset could be generated. Materials and models stay the main rubric gap.
• Draw budgets. Aura Diamond 3D Harbor (456) and Ivy (469) are over the 450 budget. Bunker Zero floor 6 draws 164 against 120.
• Game-check warnings stay at warn level (0 errors, 296 warnings: mostly luma-band rows written for older looks, none widened, and borrowed-asset rows waiting on WP-36).
