Capture writes a PNG and a `fparkan-legacy-camera-v1` JSON file; boundary-trace mode writes a log and captures no pixels. `selector0_words` remains the local camera matrix at `camera+0x20`; the capture also records `effective_world_matrix_words` from `camera+0x60` with `effective_world_matrix_space: "world"` and a `parented_camera` marker. Both local and world matrices are sampled at the World3D render entry and reread at the projection-building boundary; only a same-thread, byte-compared snapshot paired with perspective values can produce usable renderer input. A passive `iron3d.dll` callsite probe records a path only when the active call arguments and path string are verified. It also samples `Terrain+0x421DC` after verifying the GOG module hash and the `EBP - [ESI+0x144]`, remainder by `[ESI+0x150]` instruction bytes. `atmosphere_seconds` is emitted only if the sampled `EDX` phase matches that arithmetic, the raw clock matches `World3D+0x32A38`, and sample, camera, and projection share the same render thread and generation. Otherwise it is `null`. This phase does not establish a general simulation-time, weather, or RNG value. +`geometry_projection` records the renderer's perspective values at the first indexed geometry draw (`Terrain+0x1D110`) using that world's camera matrix and renderer. It is emitted only when thread, generation, renderer, viewport, far plane and FOV match the later World3D boundary. The near plane may differ: the observed world draw uses `0.5`, while the restored camera boundary contains `5`. FParkan prefers this verified object when replaying the capture. The top-level projection fields remain the camera-boundary tuple used for selected-camera preflight. Older captures without this object still load, with `render_coverage captured_projection_unverified=1`; nearby surfaces in those replays can be clipped incorrectly. Capture a fresh frame to verify them. + The JSON keeps the `fparkan-legacy-camera-v1` schema and adds `native_fog_status`, diagnostic counts, and `native_fog`. The latter is an optional passive CPU-side snapshot of the effective sink flags/RGB/range plus the paired calls to the `Terrain+0x2F230` consumer. The flags byte is raw and not a decoded fog mode. Each draw record preserves the distance argument, raw bypass dword and effective low byte, source color, output pointers, and return address. Geometry at `EBP` is included only for the verified `Terrain+0x18A6A` caller with the expected geometry vtable and slot+0x14 target; other callers have `distance_geometry: null`. The fog object is `null` unless the samples match the same render thread, camera, generation, and projection matrix and agree on sink settings. `native_fog_status` is `paired`, `conflict`, `unpaired`, or `incomplete`; `native_fog_status_reason` explains an unpaired, conflicting, or incomplete result. The counts include processed, overflow, paired, rejected, other-thread, and matrix-mismatch calls. At most 512 calls are processed per camera generation; reaching the limit stops sampling and reports an incomplete result. These fields are additive: camera-input validation continues to accept older JSON without them. This probe observes CPU consumer state; it does not set fog or change GPU state. The capture helper expects an isolated copy at `target\shadow-probe\Parkan - Iron Strategy`; the original GOG installation stays untouched.
