$$ find-cell-list-capture.cdb  —  P0 conformance retail golden capture
$$ ----------------------------------------------------------------------------
$$ Captures retail's ACCEPTED membership decision at the cottage doorway so we
$$ can pin acdream's CellTransit.FindCellList against it (P0 Task 6, the P1 gate).
$$
$$ Emits one line per accepted cell change in the golden format the parser reads
$$ (tests/AcDream.Core.Tests/Conformance/RetailTrace.cs):
$$     [fcl] seed=0xHHHHHHHH px=0x<hex> py=0x<hex> pz=0x<hex> picked=0xHHHHHHHH
$$ where seed = the cell the player was in (old), picked = the cell committed (new),
$$ and px/py/pz = the player world origin (raw IEEE-754 hex; decode offline with
$$ tools/cdb/decode_retail_hex.py, then write decimals into the golden fixture).
$$
$$ Target: CPhysicsObj::change_cell @ 0x00513390 (pc:281192) — commit-on-diff.
$$ It fires ONLY on an accepted cell transition, so the doorway crossing yields a
$$ short, clean sequence (e.g. 0031 -> 0170 -> 0171), not a per-tick flood.
$$
$$ thiscall: this (CPhysicsObj*) = @ecx ; arg new_cell (CObjCell*) = poi(@esp+4)
$$
$$ OFFSETS BELOW ARE PLACEHOLDERS — VERIFY LIVE (see README). At the first break:
$$     dt acclient!CPhysicsObj @ecx        $$ find m_position (Frame/Position) + cell
$$     dt acclient!CObjCell poi(@esp+4)    $$ find cell_id offset
$$     dt acclient!Position <m_position>   $$ find origin (x,y,z) float offsets
$$ then edit CELLID_OFF / CELLPTR_OFF / POS_OFF and re-run.
