hands/rec/validate.py (standard library; Linux and Windows, Python 3.12+)
checks an export before upload and when it's received: SHA256SUMS, an
allow-list of files, the manifest's schema and keys, the consent version,
a uuid4 contributor, no identifying fields in calibration.json or
device.json, every sets.bin.zst decompressed to its end as a stream with
each FHSET01 header checked against the manifest, jsonl lines, the total
size. It decompresses with compression.zstd, zstandard or the zstd
program. validate.py DIR [--json].
hands/rec/hub.py uploads an export with huggingface_hub, as a pull
request to contributions/<contributor>/<session>: validate first, refuse
a repeat of the same export, check the login (whoami) and access
(auth_check), upload_folder(create_pr=True) with the manifest summary as
the description, then record the PR under "uploads" in session.json.
Errors are explained (terms not accepted, not found, 401/403, network).
--dry-run makes no network calls. FT_HANDREC_DATASET overrides
HF_DATASET (DeeJanuz/frametop-hands); while the texts are drafts a real
upload needs FT_HANDREC_ALLOW_UPLOAD=1.
The Upload page shows the login with "Check again" and how to run
hf auth login in a terminal (the token never enters the window), then
Upload with a phase, progress and Cancel (hub.py as a child process), the
PR link, and a warning for an export uploaded before. The manual
command stays as the fallback. ft-handrec --hub-dry-run.
session.py also saves device.json: cv.cad_from_cal and head from
/persist/device_config.json, the labeller's shape, nothing identifying;
export copies it. Session ids with a -N suffix are accepted everywhere.
hands/rec/rehearse.sh runs it all without the headset: ft-ringplay plays
30 s of a capture into a ring, session.py records a short test script
with ft-handpanel --no-vr and a tracker, then export, validate and a
dry-run upload (--repo ID uploads for real). It runs in one frame-job
scope, deletes its data and stops its processes, also on Ctrl+C.
hands/rec/tests/test_validate.py covers good and broken exports and hub.py
without the network. The dev container gains python3-huggingface-hub.

hands/rec/ft_handrec.py + main.qml (Kirigami, dev container; host launcher
hands/rec/ft-handrec): consent (CONSENT.md, asked again when its version
changes; profile.json with a random contributor id), the before-you-start
checklist with the lighting and free-space checks, the session controls
(Space pauses, Esc stops), review with a frame-set viewer that deletes
ranges, takes and sessions, export with progress and cancel (warns while
the headset is worn), and the upload page (UPLOAD.md, the
huggingface-cli command; HF_DATASET is a placeholder). --dry-run runs
sessions without processes, for testing.
hands/rec/takes.py (standard library): indexes sets.bin and sets-N.bin
without reading pixels, reads one set's cameras, keeps deleted ranges in
take.json, and exports: deleted sets left out, zstd -10 -T2 at nice 19,
manifest.json and SHA256SUMS, nothing left behind on cancel.
CONSENT.md and UPLOAD.md are drafts pending a legal review; the window
says contributions aren't open yet. The dev container gains zstd.
