ykcheungab 73592f085f Browse a long recording from disk instead of loading it into memory
What
- record/index.py: RecordingIndex streams forces.csv once and keeps only the
  small things — one time, one validity flag, one frame id per row plus a byte
  offset every 4096 rows (~6.5 MB per 500k rows). row_range() bisects the times,
  read_rows() seeks to the nearest checkpoint and scans forward, and overview()
  folds every row into its bucket during the same pass to build a per-axis
  min/max envelope.
- read_rows(max_points, unit) decimates **while streaming**: each bucket keeps
  the extreme row of every axis in the requested unit, so a long interval never
  has to exist in memory in full and a shear spike survives a flat normal channel.
- RecordingReader: info() decimates above max_rows (default 200k) and marks
  itself decimated, with total_rows and a duration taken from the frame index
  rather than from the view; window()/window_all()/overview()/statistics() read
  the interval being asked about. list/window semantics unchanged for small
  recordings.
- force/source.py: StoreCurveSource (live memory) and RecordingCurveSource (disk
  interval + cached envelope) implement one interface — extent, window,
  envelope, statistics, duration_s — so ForcePlotsPanel asks a *source* instead
  of knowing where the data lives.
- force_plots: reads through the source (window, envelope, statistics, extent),
  which also replaces its last direct store accesses.
- playback_dialog: draws the whole-session view through window_all() in the unit
  being shown (bounded by CHART_MAX_POINTS), and says so when the view is
  decimated ("显示 N / 共 M 行") instead of letting the operator count points.
- experiment._run: a failure that lands while the files are opening can no longer
  be overwritten by the writer's own transition to "recording" (found by a flaky
  test; the state check now covers STATE_FAILED).

Why
The store releases old blocks above ~4.6 h and the replay loaded every CSV row
into Python lists before drawing anything, so neither the live browser nor the
replay could show an earlier interval of a long recording. The index makes the
disk the data source and memory a cache of what is on screen.

Verification
- shared/tests/test_history_source.py (new, 8 cases) over a 12 000-row recording:
  the index reports its rows and reads a bounded interval; a large recording is
  marked decimated with its true duration and total rows; a small one is not; an
  interval read sees the exact rows including a single peak; a decimated window
  keeps the peak; the envelope fits the whole session in ≤200 points, keeps the
  spike and is cached; the disk and memory sources agree on extent, values and
  statistics; the whole session can be read without holding it all. Shared
  suites: 146 tests, 0 failures (three consecutive runs).
- apps/studio/tools/ui_check.py: the replay section now checks the index row
  count, that an interval read spans only the interval, the envelope size and
  total_rows. 324 checks, 0 failures.
- apps/studio/tests/test_ui_smoke.py: 43 tests, 36 pass; the 7 failures are the
  unchanged sandbox/harness artifacts.
- D:/orisys_ws/_review_phase12/reproduce.py: all ten lines unchanged;
  compileall, locale and prefs parity clean.
- apps/studio/docs/record-channel.md §8 documents the index, the reader API and
  the unified source, and lists what is still hardware work.

Not in this change
- Maximum RSS / backlog / loss measurements at real resolution on the target ARM
  board (needs the hardware), and range CSV export.

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.
