LIVE_AUDIT_2026-08-05.md records the audit behind the previous commit: the
evidence for each fix, the tool invocations that produced it, and — deliberately
— the three conclusions I got wrong before the data corrected them, since each
was a plausible-sounding guess:
* "66 same-named wash lights stay lit" — that 66 is the mob_a000 crowd, not
lights. live10149 has 4 duplicated light names, 10 objects.
* "the light handlers need name -> List support first" — every one of song
1177's 28 BlinkLight group names maps to exactly one GameObject; the groups
address containers and GetComponentsInChildren already covered the children.
* "plane_000 should look lighter than the other two" — _EnvRate 0.75 vs 1.00
cannot be distinguished once the term saturates to white, so that comparison
could never have decided anything either way.
Also records which song exercises which fix, since only 1177 is downloaded
locally and it carries no bgColor2 / spotlight3d / transform data.
Stage floor blow-out (plane_000 / stage_object_001 / specular_002): four
mechanisms now ruled out rather than one cause found. Not lighting — live10149
has 10102 GameObjects and zero Light components, and the Live code never touches
Light at all. Not a missing reflection texture — StageEnvMapDiag reports 0 of 3
null. Not the unwritten _ColorPower — BgColor1's power field has a median of
1.000 on all three groups, which retroactively supports reverting that write.
Not the env reflection term — F9 zeroes _EnvRate on all three renderers, and the
log confirms it fired nine times with no visible change. Also corrects a sampling
error of mine: frame 0 is near-black, but across all 257 keys the floor's median
luminance is 0.548 and 81% of keys exceed 0.3, so it is meant to be bright for
most of the song. Next binary test is forcing _MulColor0 to black.
StageEnvMapDiag logs the env-map bindings once at stage init and attaches an
opt-in F9 toggle that flips _EnvRate between its authored value and 0 through a
property block. Diagnostic only; inert unless the key is pressed.
LIVE_DEV_MAP.md now separates "implemented" from "checked". Ten rows drop to
"OK?" because nobody has verified them — this session found four tracks that
were marked done and had never once produced output, so an unchecked mark is
not evidence of health. GlobalFog drops to partial: its data is height fog
(isDistance=0, isHeight=1) but the handler enables Unity distance fog, and
RenderSettings has no height fog. The claim that BlinkLight and Spotlight3d
drive child Light components was wrong and is corrected.
