-# Host APP Rebuild
-
-## Goal
-
-Keep the APP layer suitable for teaching from simple to complex.
-
-Teaching order:
-
-1. one button
-2. one keyboard page
-3. two pages
-4. one main window
-5. one shared theme
-
-## Completed Nodes
-
-### Node 1: theme helpers
-
-Files:
-
-- `KeyBorad/KeyBorad/APP/AppTheme.h`
-- `KeyBorad/KeyBorad/APP/AppTheme.cpp`
-
-Design notes:
-
-- centralize colors and style strings
-- keep styling readable
-- avoid mixing style text inside every widget
-
-### Node 2: key button
-
-Files:
-
-- `KeyBorad/KeyBorad/APP/AppKeyButton.h`
-- `KeyBorad/KeyBorad/APP/AppKeyButton.cpp`
-
-Design notes:
-
-- teach one custom button first
-- keep state changes explicit
-- let one widget own its own text and style refresh
-
-### Node 3: keyboard page
-
-Files:
-
-- `KeyBorad/KeyBorad/APP/AppKeyboardPage.h`
-- `KeyBorad/KeyBorad/APP/AppKeyboardPage.cpp`
-
-Design notes:
-
-- grow from one button to a full keypad
-- keep layout data local and explicit
-
-### Node 4: settings page
-
-Files:
-
-- `KeyBorad/KeyBorad/APP/AppSettingsPage.h`
-- `KeyBorad/KeyBorad/APP/AppSettingsPage.cpp`
-
-Design notes:
-
-- use a second page early
-- give transport status and action feedback one simple home
-
-### Node 5: main window integration
-
-Files updated in this step:
-
-- `KeyBorad/KeyBorad/APP/AppMainWindow.h`
-- `KeyBorad/KeyBorad/APP/AppMainWindow.cpp`
-- `KeyBorad/KeyBorad/main.cpp`
-
-Implemented behavior:
-
-- create the two-page window
-- own one `Lgc_Core`
-- start handshake on launch
-- poll the logic layer with a timer
-- refresh settings page texts from logic state
-
-### Node 6: Qt property typing fix
-
-Files updated in this step:
-
-- `KeyBorad/KeyBorad/APP/AppKeyboardPage.cpp`
-- `KeyBorad/KeyBorad/APP/AppSettingsPage.cpp`
-
-Design notes:
-
-- keep widget property values explicit under MSVC + Qt
-- avoid relying on implicit conversion from string literal to `QVariant`
-
-Implemented behavior:
-
-- replace raw `"title"` / `"body"` property values with `QStringLiteral(...)`

-# Host COM Rebuild
-
-## Goal
-
-Keep the protocol layer small and explicit.
-
-The COM layer should:
-
-- define packet-facing helpers
-- own frame parsing and packet building
-- avoid transport concerns
-- avoid UI and session concerns
-
-## Completed Nodes
-
-### Node 1: legacy protocol baseline
-
-Files already present before this step:
-
-- `KeyBorad/KeyBorad/COM/Com_Cdc.h`
-- `KeyBorad/KeyBorad/COM/Com_CdcEncode.h`
-- `KeyBorad/KeyBorad/COM/Com_CdcEncode.cpp`
-- `KeyBorad/KeyBorad/COM/Com_CdcDecode.h`
-- `KeyBorad/KeyBorad/COM/Com_CdcDecode.cpp`
-
-Design notes:
-
-- these files preserve the old packet format
-- they already encode and decode complete CDC frames
-- they also contain per-packet payload helpers
-
-### Node 2: unified protocol entry
-
-Files added in this step:
-
-- `KeyBorad/KeyBorad/COM/Com_ProtoCodec.h`
-- `KeyBorad/KeyBorad/COM/Com_ProtoCodec.cpp`
-
-Design notes:
-
-- provides a thin and readable entry point for higher layers
-- keeps `DRI` from depending on packet parsing
-- keeps `LGC` from depending on low-level byte layout details
-- starts from the smallest useful handshake path
-
-Implemented behavior:
-
-- build `HelloReq` frame
-- validate whether a parsed packet is `HelloRsp`
-- decode `HelloRsp`
-- forward frame parsing and stream extraction to the existing low-level codec
-
-## Next COM nodes
-
-- bitmap encode/decode helper
-- ack/error helper
-- time sync and theme helper
-- replace direct `Com_Cdc*` calls in higher layers with `Com_ProtoCodec*`

-# Host LGC Rebuild
-
-## Goal
-
-Keep the logic layer small, readable, and teachable.
-
-The logic layer should:
-
-- own connection state
-- own handshake state
-- call DRI for bytes
-- call COM for frame and packet parsing
-- expose a small interface to APP
-
-The logic layer should not:
-
-- parse serial bytes by itself
-- enumerate devices directly
-- own widget code
-
-## Completed Nodes
-
-### Node 1: function executor shell
-
-Files:
-
-- `KeyBorad/KeyBorad/LOGIC/Lgc_FunctionExecutor.h`
-- `KeyBorad/KeyBorad/LOGIC/Lgc_FunctionExecutor.cpp`
-
-Design notes:
-
-- keep function execution out of session code
-- reserve one place for OS-specific actions
-- keep the initial implementation small
-
-### Node 2: state model
-
-Files updated in this step:
-
-- `KeyBorad/KeyBorad/LOGIC/Lgc_State.h`
-
-Design notes:
-
-- state is plain data
-- connection text and last action text live here
-- handshake result fields live here
-
-### Node 3: session handshake path
-
-Files completed in this step:
-
-- `KeyBorad/KeyBorad/LOGIC/Lgc_Session.h`
-- `KeyBorad/KeyBorad/LOGIC/Lgc_Session.cpp`
-
-Implemented behavior:
-
-- try CDC handshake
-- send `HelloReq`
-- wait for `HelloRsp`
-- store the active transport
-- keep a stream buffer for CDC bytes
-- return the next parsed packet to upper layers
-
-### Node 4: core facade
-
-Files completed in this step:
-
-- `KeyBorad/KeyBorad/LOGIC/Lgc_Core.h`
-- `KeyBorad/KeyBorad/LOGIC/Lgc_Core.cpp`
-
-Implemented behavior:
-
-- give APP one small entry point
-- start CDC handshake through session
-- expose `Start / Poll / Close / GetState`
-- refresh state from `HelloRsp`
-- update a simple action text when packets arrive
