NayaFlow / NayaCore / flow-bg-server

Stock host stack (macOS, app v1.25.1), three processes:

Process	Binary	Role
NayaFlow	Electron app (/Applications/NayaFlow.app)	renderer UI + main
flow-bg-server	Go helper (Contents/flow/flow-bg-server -port 56486)	HTTP bridge: renderer ↔ NayaCore
NayaCore	Qt service (Contents/core/NayaCore.app/…/MacOS/NayaCore, v6.11.0)	owns USB CDC + BLE, SQLite, ZMQ REP on 127.0.0.1:56500

CI paths leaked in the binary: /Users/runner/work/NayaCore/NayaCore/… (GitHub Actions macOS runner). Full serial-side source map (embedded paths) spans Naya_SerialPort/{Naya_SerialWorker, …, Naya_DeviceManager{,_Operation,_Enqueue,_FWUpdate,_ModuleFwUpdate, _Pairing,_ClearAllData,_ClearBLEDevices,_TestSPIFlash}, MCUBootWorker/{,_CreateLeft{,_Modules},_CreateRight}, ProtocolCDCWorker/{…, Message_Worker/{Integration_Worker, Process_Worker/{…, System, BLE, Firmware, Flash, LED, META, Module, Remap, SysPower}}}}}.

What stock flashing actually does

Remap flash = per-key 30/1004 writes (+ 30/100e for colors), each verified by a full readback: READ-ALL → WRITE → READ-ALL. Stock ritual chain (static): _remapWriteLayerList → _remapReadLayerData (30/1003) → _remapWriteLayerData (30/1004) → _remapWriteModuleConfigList (30/100A) → _remapReadModuleData (30/100B) → _remapWriteModuleData (30/100C) → READ color (30/100D) → WRITE color (30/100E).

Single-key color flash = lone 30/100e on the LEFT port only; the right port gets polls only, forever (NayaFlow's path to right-half colors stays unobserved).

Dead / host-only features (no wire path)

• Settings UI for scan-mode / LED-max / LED-override-mode: ZERO ED frames on flash (only fe/100a timeouts + reads).
• Per-layer LED animations: registry {SOLID, SWIRL, BREATHE, SPECTRUM} + icons exist, animation_id NULL in DB, no renderer→backend calls.
• Macros: device store answers but is always empty; zero macro lines in NayaCore logs — NayaFlow never syncs them.
• Naya-type palette actions (MAC_OS/WINDOWS_OS/…): zero tap: hits — the device gets DISABLE/plain-HID for those slots.
• “Factory Reset” string in the UI = app-settings reset (language/ theme group), not a device wipe. There is no device-factory-reset button in stock UI.

Extracting the renderer

app.asar unpacks with a tiny header formula (jsize=u32@12, json@16, base=align4(16+jsize), offsets relative to base) or npx --yes @electron/asar extract. Interesting trees: dist/main/index.js, dist/renderer/assets/, assets/icons/action/ (860 keycap glyphs — reused for the open web client's icon set).
