- Cache files now live in recordings/analyses/<filename>.analysis.json
(mirroring the relative path for files in subdirectories) rather than
alongside each audio file.
- _api_delete now removes the corresponding cache file after deleting audio.
- prune_orphan_analyses() runs at startup and removes any .analysis.json
whose audio file no longer exists (handles files deleted outside the UI).

After the first analysis of a WAV/FLAC file, the result is written to
<filename>.analysis.json next to the audio. Subsequent requests with the
same threshold and min_gap parameters return the cached result immediately
without re-reading the audio data. The cache is invalidated automatically
if either parameter changes. Written via temp-then-replace for thread safety.

- Recordings table now groups files by day with collapsible headings
showing file count, total duration, and size; most recent day expands
by default, older days start collapsed
- Day highlights button runs loudness analysis across all WAV/FLAC files
in a day and renders a combined SVG activity timeline (blue = file
extents, orange = loud sections) with time labels
- Grace period control (default 2 s, max 300 s) merges loud sections
separated by less than this gap; exposed in the controls bar, via
--min-gap CLI flag, and as a per-request min_gap param on /api/analyze
- Delete re-renders via applyFilters so day headings stay consistent
Adds a DELETE /api/files/<name> endpoint that refuses to remove files
currently being recorded (409). The UI shows a red '✕ Delete' button per
row (disabled while REC), confirms before proceeding, and removes both
the data row and the hidden player row from the DOM on success without
a full page reload. README updated accordingly.
hw:0,0 is an exclusive ALSA device — darkice holding it caused arecord
to fail silently (stderr was /dev/null), leaving all recordings at 0 bytes
with no errors in the log.
asound.conf: defines a dsnoop virtual device 'shared_mic' that opens
hw:0,0 once and lets multiple processes capture simultaneously.
docker-compose.yml: mount asound.conf into the container as
/etc/asound.conf; add ipc: host so the container shares the host IPC
namespace (dsnoop uses System V shared memory which does not cross the
container IPC boundary without this).
config.example.ini: document the dsnoop setup and shared-device pattern.
README, CLAUDE.md: document the full setup procedure.
- Remove stale instruction to set output_directory = /recordings in Docker
- Document that docker compose down + up --build is required when updating
- Fix output_directory and log_file table descriptions
- Expand Web UI section: inline playback, FLAC waveform, live REC badge, WCAG
- Fix Docker notes: log_file path and log_file in Docker guidance
- Add rule to CLAUDE.md: always update and commit README.md with code changes
