AzuTear c7138b541d feat(native): C# input/capture sidecar replacing the PowerShell helper
Implements ADR-008. native/input-helper is a self-contained .NET 9 console exe
speaking the identical JSON-over-stdin/stdout protocol as the old PowerShell
helper (ping/cursor/runtime/focus/click/scroll/bounds/capture), so the
InputHelperService interface is unchanged.

- Win32 interop compiled once (native exe), not per call.
- PerMonitorV2 DPI via manifest so click/capture coordinates stay correct on
  mixed-DPI multi-monitor setups.
- capture returns base64 PNG bytes inline (imageBase64) instead of writing a
  temp file per frame; the client handles both base64 and the PowerShell path.
- InputHelperClient prefers the exe and falls back to the embedded PowerShell
  helper when the exe is absent, so the app still runs without the .NET build.
- main.ts resolves the exe (INPUT_HELPER_EXE env -> packaged resources/input-helper
  -> native/input-helper/bin/publish). electron-builder ships it via extraResources.
- npm run helper:build; README documents the build + fallback.

Verified end-to-end through the compiled client: sidecar spawns, runtime info
and a base64 primary-screen capture return correctly. Build stays green.

Genshin Artifact Assistant

Local Windows-first Electron app for scanning Genshin Impact artifacts, triaging them, and suggesting simple character builds without depending on Inventory Kamera or Genshin Optimizer as the main workflow.

Current MVP

  • Electron + React + TypeScript app shell.
  • Dark purple fintech/glassmorphism UI direction.
  • Genshin capture source discovery.
  • Smart Capture that focuses Genshin, hides the app, captures the primary screen, and restores the app.
  • Artifact detail-panel crop detection with focused OCR regions.
  • OCR parser for artifact name, slot, main stat, substats, set, equipped character, confidence, and review notes.
  • Demo triage and build suggestion views.
  • Read-only overlay preview shell.

Documentation

This project uses the engineering template from https://git.noveria.net/bao/template adapted to this app:

Run

npm install
npm run dev

Use the Electron app window for scanner work. The browser preview does not expose the local capture bridge.

Input/Capture helper (C# sidecar)

Input automation and screen capture run through a compiled C# sidecar (native/input-helper, see ADR-008). Build it once:

npm run helper:build   # requires the .NET SDK; produces a self-contained exe

The app auto-detects the exe (INPUT_HELPER_EXE env override → packaged resources/input-helpernative/input-helper/bin/publish). If the exe is not present it falls back to the embedded PowerShell helper, so the app still runs without the .NET build - just slower and with the old per-frame temp-file capture.

Automatischer Scan: als Administrator starten

Genshin läuft erhöht (Administrator). Windows (UIPI) verwirft dann alle simulierten Maus-Eingaben aus einer nicht-erhöhten App - SendInput meldet dabei trotzdem Erfolg. Für den automatischen Scan muss die App deshalb ebenfalls erhöht laufen:

  • npm run dev:admin (oder Doppelklick auf dev-admin.cmd) - öffnet aus einem normalen Terminal heraus einen UAC-Prompt und startet danach npm run dev in einem neuen Administrator-Fenster.
  • Alternativ: Terminal per Rechtsklick "Als Administrator ausführen" öffnen und darin normal npm run dev starten.

Der UAC-Prompt lässt sich nicht dauerhaft abschalten; das ist Windows-Design. Die gepackte App fordert Admin-Rechte über requestedExecutionLevel: requireAdministrator selbst an. Die App zeigt im Scanner-Header und in der Scanner-Diagnose nur an, ob sie gerade erhöht läuft - sie startet sich nicht selbst neu.

Validate

npm run lint
npm test
npm run build

Safety Boundaries

  • No memory reads.
  • No hooks or process injection.
  • No game file modification.
  • No automatic delete, enhance, feeding, or resource-spending actions.
  • In-game lock/marking is a future opt-in module and remains disabled in this MVP.
