ewsdrd.lpr — a console daemon that runs TRadioController + TWebAdapter WITHOUT
TMainForm/LCL, proving the Phase-5 goal: web-only headless operation. THeadlessHost
wires the data-path callbacks to the controller, the web command handlers to the
adapter (lifecycle ones marshalled to the main thread via FCtrl.Invoke =
TThread.Synchronize), opens WDSP synchronously, autostarts the saved device, and
runs a CheckSynchronize + periodic PushState loop. SIGINT/SIGTERM → graceful
StopAndDisconnect (persist + Run=0).
To keep the controller graph truly LCL-free, PlatformUtils now guards its only
Forms dependency (Screen.PixelsPerInch in CurrentScreenDPI) behind {$IFNDEF
HEADLESS}; the GUI build is byte-identical (HEADLESS undefined). build-ewsdrd.sh
compiles the headless graph from source with -Mobjfpc (nested comments) -dHEADLESS
into a separate lib-headless/ output dir, untouching the GUI .ppu.
Verified: builds clean; runs headless, web server up (HTTP 401 = serving), no LCL;
SIGINT shuts down gracefully. Radio-connect + web round-trip need hardware to test.
