# Conformance fixtures

Captured retail golden data for the P0 conformance tests.

- `find-cell-list-threshold.log` — retail `find_cell_list` picks at the Holtburg "Agent of
  Arcanum" doorway (the `0031↔0170↔0171` building), in the
  `[fcl] seed=0x.. px=.. py=.. pz=.. picked=0x..` format read by `RetailTrace.ParseFindCellList`.
  **Captured ALIGNED** by `tools/cdb/find-cell-list-capture-aligned.cdb`: each row's position is
  the COMMITTED position read from the `set_frame` call that follows `change_cell`, so cell and
  position are from the same instant.

  History (2026-06-03): the first capture (`tools/cdb/find-cell-list-capture.cdb`) read position
  from `m_position` AT the `change_cell` breakpoint — but `SetPositionInternal` calls `change_cell`
  (`acclient_2013_pseudo_c.txt:283456`) BEFORE `set_frame` writes `m_position` (`:283458`), so each
  row paired THIS frame's new cell with the PREVIOUS frame's position (a one-frame skew,
  `picked[i] == geom(position[i+1])`). That skew made the conformance read 0/11 and was
  briefly misdiagnosed as a "membership lags retail" bug. The aligned golden removes the skew;
  acdream's center-only `point_in_cell` pick matches retail 9/9 on the indoor crossings with **no
  code change** — acdream's membership already IS retail's true per-frame behaviour. See
  `docs/research/2026-06-03-p1-membership-swept-advance-handoff.md`.

Fixtures are read from this SOURCE directory (via `ConformanceDats.FixturesDir`), not copied to
the build output — matching the existing `Fixtures/issue98/**` pattern.
