New core::IDsp::writeRawParam(address, value) safeloads any named
Parameter RAM cell in the compiled SigmaStudio program (74 cells: mixer/
Beep1/PEQ coefficients/limiter thresholds/etc — the same set SigmaStudio's
own Remote Connection, components/net/SigmaStudioTcpServer, already has
full access to). Value is a plain SigmaStudio floating coefficient,
converted to ADAU 8.23 fixpoint via the existing core::floatToFixpoint823.
Adau1701ParamTable.hpp holds the name->address table extracted from
Firmware/ADAU1701-Firmware/DigiRadio_IC_1_PARAM.h; core::DspParamJson
handles the wire format without core/ depending on the adau1701 driver
(net/SetupWebServer.cpp bridges the two, consistent with how other
JSON DTOs are supplied their data by the net layer).
GET /api/dsp/params lists every cell (name + address) for discovery.
PUT /api/dsp/param {"name":...,"value":...} writes one. Deliberately no
domain validation, matching the trust level already implied by the
existing SigmaStudio TCP bridge being reachable on the same network.
HTTP routes were registered in the SetupWebServer.cpp change committed
alongside the FM band scan feature (3a10ed7).

Claude-Session: https://claude.ai/code/session_0178rASQ6ZETPMUamvpoR2KR
- 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.

Expose POST /api/audio/stereo-enhance and bass-enhance with 0–100 levels,
persist enhancements in AudioProfile, and document the virtual EQ mapping in
the manual and SigmaStudio chapter.

Safeload mixer/EQ/master on the ADAU1701, persist AudioProfile in NVS,
expose /api/audio routes and web UI controls, with host tests and manual sync.
