- NvsAudioProfileStore used the key "audio_profile_json" (18 chars),
exceeding NVS's 15-char key-name limit. Every nvs_set_str call failed
silently with ESP_ERR_NVS_KEY_TOO_LONG (0x1109): applyProfile() always
updated live DSP audio correctly, so the bug was invisible except as
"store_failed" in the HTTP response and settings never surviving a
reboot. Renamed to "audio_profile" (13 chars); confirmed live, EQ/mixer
changes now persist across a reset.
- The hand-rolled JSON extractJsonString()/extractJsonBool() helpers
(duplicated per-file: TunerJson, DspParamJson, StationListJson,
WebRadioJson, WifiProvisionJson, AudioProfileJson, plus inline mac/name/
save parsing in BluetoothJson) matched only the exact literal
`"key":"value"` / `"key":true`, with no tolerance for a space after the
colon. Standard JSON encoders (e.g. Swift's JSONEncoder in its default,
non-compact mode) emit `"key": "value"`, which silently failed to parse
as invalid_json/missing_field. Numeric fields were already fine
(strtoul/strtof skip leading whitespace per the C standard); fixed only
the string/bool extractors to skip whitespace after the colon before
matching the value.

- Add docs/si4684-rf-investigation-report.md: full record of the FM/DAB no-lock
investigation (crystal, front-end matching, ANTCAP sweep, continuity, leading
EP solder-defect hypothesis, PCBWay report sent) plus the separate audio
profile NVS bug found and partially fixed this session.
- Fix sigma_i2c_write() (SigmaStudioFW.c): no retry on I2C failure meant a single
transient NACK anywhere in a long safeload burst (EQ apply = ~55 sequential
transactions) aborted the whole sequence. Added a 3-attempt retry.
- Add granular failure logging (AudioService::applyProfileToDsp/persistProfile,
Adau1701Driver::applyMixer/applyEq, NvsAudioProfileStore::saveProfile error
codes) to isolate the remaining NVS-side audio profile save failure.
- Si4684Driver::tuneFm gains an optional ANTCAP argument (default 0 = unchanged
auto-tune behavior) used during this session's front-end matching sweep.

Streaming (main feature this session):
- New WebRadioConfig/WebRadioJson core types, ISecureStore-backed persistence
- New webradio::WebRadioService (thread-safe live config) + GET/POST /api/streaming
- web_radio_stream task now runtime-toggleable (no reboot), no hardcoded URL
- Content-Type diagnostic: warns clearly when a URL is a webpage, not an audio stream
Boot cleanup:
- Removed boot-time auto FM/DAB tune, auto-beep, and the (now-concluded) Si4684
crystal IBIAS/CTUN empirical sweep from main.cpp — tuning/beep are on-demand
via the existing REST API only
Web UI:
- Modernized styling (cards, gradients, toggle switches, light/dark theme)
- New Stream tab wired to /api/streaming
Fixes found via real idf.py build (not just clangd):
- Restored wrongly-removed si4684/Si4684Tuner.hpp include in main.cpp
- Fixed MP3Decode() argument types in web_radio_stream.cpp (unsigned char**/int*)
Quality-gate fixes:
- Host-test stub headers (esp_log.h, freertos/*) so TunerService.cpp's
scanForStation logging/pacing compiles for station_service_test /
integration_service_test instead of running stale binaries
- Added WifiScanner and WebRadioService manual sections; filled in missing
Doxygen docs on BluetoothService, i2s_sdata_probe, test_firmware, Bt1035At
- Ignore clangd's .cache/ index directory
Also includes prior uncommitted work carried in the tree: Wi-Fi/Bluetooth
device scan REST API and UI (WifiScanner, BT scan), SigmaStudio TCP bridge,
and the current ADAU1701 SigmaStudio DSP program export.
