ykcheungab 817f830565 record the full experiment: video, CSV and metadata
Phase 1 of the review asked for one directory per experiment, a force CSV,
video of the pre-processing image, and metadata that ties them together. The
record channel from the previous change already kept the whole session; this
adds the on-disk format.

What
- Add record/experiment.py: ExperimentRecorder writes one directory per
  session containing session.json, forces.csv, frames.csv, events.csv,
  raw_NNNN.mp4 (segmented) and an optional lossless PNG sequence.
- forces.csv uses the reviewed column order
  (session_id, frame_id, t_rel_s, FN_raw, FX_raw, FY_raw, FN_N, FX_N, FY_N,
  valid, calibration_id) and leaves a cell empty when a value is unavailable:
  an uncalibrated newton value or a failed readout is never written as 0.
- frames.csv is the frame-index mapping: frame_id, t_rel_s, acquisition wall
  clock, segment, segment_frame, in_video. forces.csv and frames.csv share the
  packet frame_id and the same t_rel_s origin, so video and data can be
  aligned after dropped or segmented frames.
- session.json carries format version, session id, start/end time in UTC,
  device and config (with a sha256 of the config file), app/shared/SDK
  versions, calibration reference, axis convention, filter parameters, video
  codec and the lossy-MP4 caveat, plus the event log and end-of-run statistics.
  It is written once at start so a crash still leaves identifiable metadata.
- Add a record control to the toolbar: mode (video+data / data only) and a
  start/stop toggle that stays enabled while recording.
- Log zeroing, calibration application and session end as timestamped events.

Why
- The recorder is fed from the worker sink list on the acquisition thread and
  only appends to a bounded queue, so disk I/O can never stall acquisition.
- On_packet copies the raw frame instead of holding a reference: the packet
  frame may alias a buffer the SDK reuses between frames.
- A queue overflow is counted and alarmed (rate limited), and a write or encode
  failure is counted, reported and after 5 consecutive errors stops the
  recording with failed=true rather than silently losing data.

Verification
- shared/tests/test_experiment_recorder.py: 12 cases covering the directory
  layout, the CSV contract, frame-id/time-base agreement, segment rolling,
  data-only and lossless modes, queue overflow accounting, encoder failure,
  metadata fields, crash-before-stop, and that on_packet never blocks.
- tools/ui_check.py gains an "experiment record" section (169 checks, 0
  failures overall), driving a recording through the UI and asserting the
  layout, the empty-cell rule and the event sequence.
- apps/studio/tests/test_ui_smoke.py mirrors those invariants.
- docs/record-channel.md documents the format and the remaining phase-2 work.

Not in this change: CSV export of a selected time range, full-session curve
browsing, calibration diagnostics (outlier exclusion, fit residuals) and
PyOpenGL 3D.

orisys-app

Desktop applications that consume the Orisys SDK.

App Status
apps/studio Scaffold shell (theme / locale / prefs / logging)
apps/internal Stub for future calibration & automated testing

Layout

  • shared/ — common paths, prefs, theme, i18n, logging
  • apps/studio/config/ — locales, default prefs, editable sensors/ copies
  • apps/studio/outputs/ — generated logs and calibration exports (gitignored)
  • build/ — Windows PyInstaller packaging (build/studio/build.ps1)

Run (studio shell)

cd D:\repo\orisys-app
python -m pip install -e .\shared -e .\apps\studio
python .\apps\studio\run.py

Or without install:

$env:PYTHONPATH = "D:\repo\orisys-app\shared\src;D:\repo\orisys-app\apps\studio\src"
python D:\repo\orisys-app\apps\studio\run.py

Local orisys SDK

orisys_app_shared.force imports orisys.calibration at module scope, so the studio app cannot start against an SDK build that predates that module (the published 0.5.2 wheel does not include it). When working from a repo checkout, install the SDK from source instead of from an index:

python -m pip install .\..\orisys-sdk          # same checkout that built this app

If a pip build is blocked by the environment, the equivalent manual install is to copy orisys-sdk/src/orisys/**/*.py over site-packages/orisys/ and delete the stale __init__.cp310-win_amd64.pyd (an extension module shadows the package __init__.py, which hides sibling modules such as calibration.py).

Verifying UI changes

Both tools render the real main window with the offscreen Qt platform — no display, camera or sensor hardware required:

python .\apps\studio\tools\ui_check.py                      # layout/theme assertions
python .\apps\studio\tools\ui_snapshot.py --theme light --demo `
    --sensor finger --panels cal,3d --size 1600x900 --out shot.png

ui_check.py needs only the runtime dependencies. The pytest suite in shared/tests and apps/studio/tests covers the same ground plus locale and preference-schema parity:

pip install pytest
python -m pytest

On Windows the offscreen platform finds no fonts unless QT_QPA_FONTDIR points at C:\Windows\Fonts; both tools set it automatically.

ui_check.py also runs the palette rules (WCAG contrast, colour separation, ramp monotonicity) that guard the brand tokens; see apps/studio/docs/ui-palette.md for the colour system, its relationship to the UI design spec, and every deliberate deviation from it.

ui_check.py includes a record channel section as well; see apps/studio/docs/record-channel.md for why recording and calibration sampling no longer hang off the UI refresh timer, and for the data-reliability fixes that came with it.

Branding

Window / EXE icon: shared/resources/branding/logo.png
Top bar / About: shared/resources/branding/logo_topbar.png

Dark mode is the default. Logos currently sit on a black tile; a transparent (or light) variant may be needed for polished light mode later.

Versioning

  • Studio app version (orisys_studio.__version__) — shown in Help → About and used for releases.
  • Shared package version (orisys_app_shared.__version__) — internal library version.
  • Shared API (orisys_app_shared.API_VERSION) — compatibility tag. Studio declares REQUIRES_SHARED_API; startup logs a warning on mismatch.

Deferred

Run/Stop pipeline, arrow/force plots, units, calibration capture, Open3D finger mesh, sync-from-wheel for config/sensors, PyInstaller packaging, and the internal app.
