Multi-stage image built from the `web` extra only, so it carries no Qt: the
whole web path (webapp, web_session, metrics_json, and the shared analysis
modules) imports no Qt, pyqtgraph or matplotlib canvas. The build stage has the
compiler scipy/numba need; the runtime layer installs the built wheel, so the
same image works from a checkout or a release tarball.
Compose declares no audio volume on purpose. The app keeps no audio, so there is
nothing to persist: `read_only` plus a /tmp tmpfs means request spools are
memory-backed and never reach a disk. Publishing is loopback-only because the
tool has no authentication, and BLAS thread pools are pinned because analysis is
CPU-bound.
Fix three packaging bugs the build surfaced, each of which broke the image:
- `pip install --extra web` is not valid for a source tree; uv wants `.[web]`
and failed with "Requesting extras requires a pylock.toml".
- The wheel shipped no static assets at all. `package-data` keys match
*packages*, and the app modules are top-level `py-modules`, so the `"*"` key
matched nothing - verified by inspecting the built wheel: 14 .py files, zero
HTML/JS/CSS. An installed `ujm-web` would have 404'd every asset. `static/` is
now declared a package (hence its packaging-shim `__init__.py`) so the assets
install next to the modules, which is where `webapp.py` looks for them.
- The Dockerfile's curated COPY list omitted modules that `py-modules` requires,
failing the build with "file <module>.py not found". It copies the checkout,
filtered by .dockerignore.
Move PyQt5/pyqtgraph into a `desktop` extra so the web install is genuinely
Qt-free. Verified: `find` for Qt in a web-only venv now returns nothing, and the
desktop path still resolves and imports.
Add scripts/make_fixtures.py so the smoke suite has no network or ffmpeg
dependency (the tagged MP3 is optional and its assertions skip when absent), and
make the suite tolerate that. Verified against the *installed package* running
the container's own command line, from a directory with no source tree:
61/61 passing.
Also correct README claims that had gone stale: BPM (removed), the matplotlib
canvas (replaced by pyqtgraph), and font_control_widget.py (deleted).
Reuses the analysis backend unchanged. metrics.py already split compute()
from build_spec(), and plotspec.PlotSpec is backend-agnostic, so the web UI
reimplements only the renderer: uPlot for curves/bands, a canvas for the
spectrogram heatmap. No PyQt5, pyqtgraph or matplotlib on the web path.
Uploaded audio is never persisted on the host. The browser copies each file
into Origin Private File System (sandboxed browser storage) and streams the
bytes to the server per request; the server spools each body to a temp file,
decodes, computes, and unlinks it in a finally before responding. There is no
upload directory, no cache of audio, and no session state keyed on a path:
file_id is the SHA-256 of the audio, so re-sending a master for another metric
reuses the first decode. Verified: a spool is observable mid-request and gone
after the response.
Being precise: the bytes do have to reach the server, since librosa decodes
from a path and the analysis is CPU-bound numpy/scipy. The claim is that
running this does not accumulate masters on the host, not that audio is never
on the machine mid-request.
New:
metrics_json.py PlotSpec/metric data -> JSON (the renderer seam)
web_session.py headless analysis session, content-addressed tracks
webapp.py FastAPI routes, raw-body analysis, ujm-web entry point
static/ browser front end + test suite
scripts/webapi_smoke.py 61 end-to-end assertions against a running server
Also fixes a bug the direct-uvicorn dev loop had hidden: the CLI advertises
logger_setup's WARN level but passed it straight to uvicorn, which only knows
'warning' -- `ujm-web --log-level WARN` died with KeyError: 'warn'.
Removes an earlier /api/collect debug route that served every source module
over HTTP.
pyproject: 'web' extra (fastapi, uvicorn, python-multipart), package-data for
static/, Apache-2.0 licence.
- SpectrogramMetric: log-frequency STFT power heatmap over time, magma
colormap, -80 dB floor. Adaptive hop caps time bins at ~4000 so long
tracks stay responsive on redraw; N_FFT=4096 keeps low-freq resolution.
- master_core: load audio at native sample rate (librosa.load sr=None)
instead of librosa's 22050 Hz default, so the full band up to the
file's own nyquist (~22 kHz at 44.1 kHz) is analysed. ~2x heavier on
44.1/48 kHz files, by design.
- metrics: shared _show_axis_extents helper forces each axis's exact
min/max onto the tick list with compact labels (_fmt_tick), so the
true range is always readable -- notably the spectrogram's 22 kHz top,
which otherwise sits unlabelled between log-scale decade ticks. Applied
to all metric renders.
- Docs: README + CLAUDE updated for the new metric, native-rate loading,
and axis-readability behaviour.

Introduce a Metric ABC (compute on worker thread, render on GUI thread)
with a METRICS registry, and refactor the analysis pipeline around it.
RMS power (ported), raw waveform, and BS.1770 LUFS (via pyloudnorm) ship
as the initial three; new metrics drop in by appending to METRICS.
- metrics.py: Metric ABC + RMSPowerMetric, WaveformMetric (locked to
+/-1.1 y-range for float headroom), LUFSMetric (short-term 3 s window
+ integrated value, with streaming-target reference line).
- plot_control_widget.py: metric selector dropdown + Refresh Plot button
(moved out of FontControlWidget).
- analysis_results_manager.py: AnalysisResult caches the AudioFile and a
per-metric data dict; new MetricComputeWorker runs metric switches off
the GUI thread via metricComputeStarted/metricReady/metricComputeError
signals, so LUFS on a 12-minute track no longer stalls the UI.
- main.py: all redraw paths funnel through one _render_or_request helper;
stale-result guards keep slow computes from overwriting fresh selections.
- plotting_engine.py removed (metadata text moved onto AnalysisResult;
figure construction lives in each Metric).
