$$ A7 Fix D (#140) — wall-torch vs portal light OWNERSHIP + the actual LIGHTINFO
$$ values that feed the EnvCell wall bake. 2026-06-18.
$$
$$ Decomp already settled the render path (workflow wf_f660eb88):
$$   STATIC lights -> CPU per-vertex bake (SetStaticLightingVertexColors ->
$$     calc_point_light), DOUBLE-clamped (per-light min(scale*color,color) +
$$     per-vertex [0,1]) -> walls stay DIM even at intensity=100.
$$   DYNAMIC lights -> D3D hardware FF (minimize_envcell_lighting).
$$ Render::insert_light copies intensity VERBATIM to BOTH paths, so the only
$$ open empirical question is: which light carries intensity=100, and what do
$$ the actual wall-torch LIGHTINFOs look like (intensity/falloff/color)?
$$
$$ CLASSIFICATION via config_hardware_light's d3dLightIndex (arg1 @ [esp+4]):
$$   add_dynamic_light base index = 1   -> dynamic idx in [1..10]  (viewer light / teleport PORTAL)
$$   add_static_light  base index = 11  -> static  idx in [11..70] (WALL TORCHES, baked)
$$
$$ config_hardware_light(d3dIndex, _D3DLIGHT9* out, ulong cellID, LIGHTINFO* info):
$$   d3dIndex = dwo(@esp+4) ; LIGHTINFO* = poi(@esp+0x10)   (PROVEN last session)
$$ add_static_light / add_dynamic_light(LIGHTINFO* info, cellID, Frame* offset):
$$   LIGHTINFO* = poi(@esp+4)
$$ `dt acclient!LIGHTINFO <ptr> type intensity falloff color` resolves the
$$   float fields symbolically (PDB types) -> readable values, no hex reinterp.
$$
$$ USAGE: with retail in-world standing in/near the Holtburg meeting hall by a
$$ wall torch, WALK around the hall (and past the teleport portal if present)
$$ for ~15 s so static torch sets re-register. Auto-detaches (qd) after 600
$$ total hits, leaving retail running.
