Stdlib-only identity (SequenceIdentity: id = recording_id = filename) and layer-major path layout with overridable roots; exoego:v2 entity-path and video_time timeline constants as code; atomic tmp -> os.replace rrd publication (exists = done, --force); local_verify transport with typed stubs for the HOCap-era fetchers. Unit-tested without data.

First step of the dataforge work plan (design report in packages/dataforge/docs): the stdlib-only contracts, unit-tested without data.
SequenceIdentity(borrowed from simplecv's exoegosequence_identity.py): one value derivessequence_key,recording_id, and — per the "id = filename = key = segment" rule — the rrd filename stem.data/dataforge/rrd/<layer>/<recording_id>.rrd, raw treedata/raw/<dataset>/…; roots overridable viaDATAFORGE_OUTPUT_ROOT/DATAFORGE_RAW_ROOT(defaults package-local; batch runs point them at the NAS).video_timetimeline,/world/rig_NN/cam_MM/pinhole/video, the (until now reserved)/world/rig_NN/imu_MM/{gyro,accel},property:capture:*keys.os.replacerrd publication (pattern from arkitscenes-download),should_skip(exists = done,--force).local_verify(robocap's download is verify-only) plus typedNotImplementedErrorstubs forhf_fetch/http_fetch/gdrive_fetch(land with HOCap).All dev gates green:
pixi run -e dataforge-dev {tests,lint,typecheck,deadcode}(22 tests).Next PR in the stack: the robocap end-to-end slice (convert one segment: 6-cam video + Kalibr fisheye62 calib + dev0 IMU from the SQLite
.db, register + view).
