+## Missing source files
+
+WildDet3D and hyperism packaging skips referenced source files that return
+ENOENT. Missing metadata excludes that catalog row; missing RGB/depth excludes
+the whole WDS block (including lookahead). Frame positions and surviving sample
+keys are never renumbered. Corrupt metadata, invalid/empty assets and permission
+errors remain fatal. Other sources retain strict packaging by default; the
+catalog option `skip_missing_files` can explicitly override this policy.
+
+Each run records `production/<dataset>/missing_sources.json` and an append-only
+JSONL under `missing_sources/`. Completed audit logs and summaries are published
+under `filtering/<dataset>/` with manifest provenance and remote hash checks.
+Counts denote skipped blocks/metadata rows, not necessarily unique frames.
+This records unavailability, not proof that a quality filter removed a file.
+For hyperism the unavailable test partition is omitted, never relabeled train.
+An entirely missing source fails instead of publishing an empty completion.
+
+Use the matching SpatialEncoder checkout for native training: its loader skips
+missing referenced source files, replenishes from valid clips, and bounds
+consecutive skips. Set `SPATIAL_MISSING_SOURCE_LOG_DIR` for per-worker JSONL
+audits or `skip_missing_files=False` for strict loading. WDS uses embedded
+assets and does not need the original paths; broken WDS asset bindings still
+raise errors. Existing checkpoint keys/fingerprints are always validated.
