The second real session took 16 minutes, half of it 36 still poses. Labels
come from the auto-labeller, so what matters is variety, not clean holds.
A sweep step shows a strip of pose pictures and lights one every 4 s while
the hands move slowly near and far; each cue is a prompt event with
"cue": true. The core session is now 15 steps, about 5 minutes recorded.
The pose groups, the one-hand sweeps' groups and the cue order are shuffled
per session, seeded from its id and saved in session.json. A quick round
(--quick, or the checklist's choice) is about 2 minutes for extra lighting.
Touch the dot has 6 dots, the push sections two heights.

After the headset wakes, XRService sometimes fails to load the colour module's
VCINT FPGA image; then only the two side cameras run, without the IR light,
and the tracker finds no hands. hands/camcheck.py reads XRService's log, the
video nodes it holds and ft-camd's ring, and says ok, degraded or unknown.
The recorder won't start while degraded (--ignore-cameras overrides it), offers
a confirmed SteamVR restart, and stops the first hand-size step when the
tracker sees no hand at all. ft-camwatch (unit file only, not enabled) follows
the log, notifies, and with CAMWATCH_AUTO_RESTART=1 restarts SteamVR when the
headset isn't worn and nothing else uses VR.

The headset's right-side click button (KEY_SELECT on gpio-keys, read without
a grab) now works the session: Next while a step waits, pause during a hold,
resume while paused. With no mouse connected the hints lead with it.
The push sections say plainly to push straight out from the headset and pull
back, with a side-view picture of the head, the headset and the arrow, and
the bar's ends read "At your chest" and "Arm out". The bar labels are sent
as one field, so labels with spaces no longer split.

The first real session moved on every 5 s with text only, too fast to follow.
Each step now waits for Next (Space or the window's button), counts down 3-2-1
while recording, then holds. P pauses, R redoes a step, S skips a section;
"Advance by itself" (--auto) keeps the old timed flow. Nothing records while
a step waits: each step is its own recording part.
The panel and the window show a picture of each pose (hands/rec/poses,
generated by make_poses.py from a parametric hand, MIT) and a diagram of where
to hold the hands and how far out. prompts.jsonl gains ready, wait and redo
events; session.json gains mode.

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.
