Dual-lens Opus review of 7e0c1303 (reports committed under
docs/research/). The law, gate, and vertical application are CONFIRMED
at instruction-byte level against the PDB-paired acclient.exe (the BN
text FPU-elides this whole area); the fix round addresses the findings:
- Blast MUST-FIX 1: real schema migration instead of a hand-edited dev
file. SettingsStore v2->v3: a pre-v3 display.fieldOfView was the
applied vertical FOV in degrees; v3 means retail's m_fGameFOV.
LoadDisplay migrates on read - the untouched old default 60 maps to
the retail default 90; a deliberate other value preserves its visible
16:9 framing (x (16/9 - 0.1)), clamped to the registered [10,160];
the next save stamps v3 and migration never reruns. The dev
settings.json hand-edit was reverted so the migration owns it.
- Blast MUST-FIX 2 / mechanism M2: the Field of View now applies LIVE on
Save (retail: Render::GRPCallback_OnRenderPreferenceChanged @0x0054d999
-> SmartBox::SetDefaultFov). RuntimeSettingsTargets gains the camera
graph and applies through ApplyDisplayWindowState - the update-phase
seam, deliberately NOT the render-phase preview path (the review's
WATCH-3 cull-vs-raster landmine).
- Mechanism M1 -> register row AD-90: retail's divisor aspect runs
through the Render.AspectRatio preference (ComputeAspectForViewport
@0x0054f150, (w/h) x pref x 0.75) - exactly raw w/h at the registered
default, which is what acdream assumes; retail's NaN-through-the-gate
quirk (M3) is folded into the same row as deliberately not reproduced.
- Docs: RetailFieldOfView now cites the decisive vertical proof
(D3DXMatrixPerspectiveFovLH fovy slot @0x0059ab71), the unconditional
SmartBox::RenderNormalMode site, and M4's exact horizontal numbers
(89.0/83.9/80.6 deg); the Config FOV row comment updated to LIVE.
- Blast WATCH 4 disposition: the 15 replay-harness PI/3 constants stay -
they are CAPTURE-TIME camera parameters for recorded fixtures, not
production framing; changing them would invalidate the replays.
Tests: +6 SettingsStore migration facts, +1 live-apply fact.
App suite 4,962/3 skips; UI.Abstractions 922.

Retail's world-camera FOV is not a constant: the applied vertical FOV is
m_fGameFOV / (viewportAspect - 0.1), recomputed on every aspect or
game-FOV change (CreatureMode smartbox sites 0x00452b2f/0x00453b14),
gated by Render::SetFOVRad's open (0, pi) acceptance (0x0054b2d0 -
rejected results keep the previous FOV). m_fGameFOV defaults to pi/2 =
90 degrees (0x00454649) and is what the Field of View option sets in
degrees (0x00451e6a; registered range [10,160] default 90 -
gmClient::InitUIPreferences @0x004035b0). Net effect: the horizontal
view stays ~85-90 degrees across aspect ratios; wide screens trim the
vertical slice instead of ballooning the sides.
acdream hardcoded FovY = pi/3 = 60 degrees on all four world cameras,
aspect-independent, and the Config slider wrote raw vertical-FOV
degrees. New: RetailFieldOfView (the law + gate, decomp-cited),
CameraController.GameFovRadians + SetGameFov + one ApplyProjection
chokepoint recomputing every camera on SetAspect/SetGameFov/
EnterChaseMode/RestoreState; ApplyFieldOfView now feeds the law;
DisplaySettings.Default.FieldOfView 60 -> 90 (the retail registered
default; the stored number changed MEANING with this commit).
The same seam closes a second latent bug the 2026-08-13 "squished" gate
report exposed: SetAspect only ever updated Orbit/Fly - the CHASE
cameras (the ones the player looks through) kept their creation-time
aspect across every mid-session resize, drawing the world at the old
shape stretched onto the new viewport.
The paperdoll camera stays outside the law by design (retail portrait
mode is UseSharpMode, not smartbox - DollCamera's own doc).
Tests: RetailFieldOfViewTests (golden law values at 4:3/16:9/21:9, the
constant-horizontal property, the rejection gate, controller propagation
incl. chase attach/restore + rejected-law aspect-still-propagates);
DisplaySettingsTests + RuntimeSettingsControllerTests updated to the new
semantics. App suite 4,953/3 skips; UI.Abstractions 916/0. AD-89 retired
in this commit; user settings.json migrated 60->90 by hand (stale
pre-port default).
