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/session.py runs a recording session from script.json: it starts
ft-camd and a tracking ft-hands as transient units only if they aren't
running, records each section as one take (ft-hands --record-only at
10 sets/s, a new sets-N.bin after each pause), drives ft-handpanel, and
writes session.json, calibration.json (identifying fields removed),
prompts.jsonl and take.json. Feedback comes from the live hands file and,
in the controller sections, from the panel's device poll. It also runs
from the command line (--dry-run, --speed, --ring, --no-start).
hands/rec/script.json: 11 sections, about 9 minutes without the object
and controller sections.
