# Genshin Artifact Assistant
Local Windows-first Electron app for scanning Genshin Impact artifacts, triaging them, and suggesting simple character builds without depending on external scanner or optimizer tools as the main workflow.
## Current MVP
- Electron + React + TypeScript app shell with a C# sidecar for fast read-only scan input/capture.
- Artifact-first scanner scope. Weapons, materials, and character details are intentionally not active scanner features yet.
- Smart Capture for the currently visible artifact detail view with focused OCR crops, parser confidence, and review notes.
- Visible-inventory auto-scan baseline with read-only tile selection, detail verification, OCR, parse, store/review, scroll, and summary.
- Native IK-style artifact capture path that writes card crops and run artifacts for post-capture processing.
- Packaged full-owned-inventory acceptance at 2,211 Artifacts over 70 pages,
followed by current-package reprocessing at 136 Review (6.15%), 0 errors,
and 0 store writes.
- Vendored Inventory Kamera `inventorylists` under `data/ik-inventorylists` as artifact reference data.
- Scan result rail plus Inventory view for native results, stored artifacts, crop previews, IK/GOOD match state, explicit promotion, single-result review/edit/approve, and Artifact-only pipeline state.
- Deterministic roll-efficiency evaluation with reason codes and no fake build-fit claim.
- Score-free, versioned Build-Fit V1 evidence contract plus deterministic
five-slot/Set/aggregate/conflict verification, a four-profile sourced corpus
(Furina, Neuvillette, Raiden Hyperbloom, Nahida Deepwood), explicit source
expiry, and a separate read-only evidence-coverage ranker. The Builds view
shows at most three explainable native-scan suggestions; it never treats
Roll-Efficiency, OCR confidence, character ownership, team, weapon, or
rotation as a guessed fit score.
- Detail-only Worst/Middle/Best upgrade projection for under-leveled, unambiguously identified 5-star Artifacts with four known legal substats.
- Offline replay gate for existing native scan results and an unpacked-package resource/ASAR verifier.
- GOOD import/export, review samples, OCR eval, diagnostics, local artifact store, demo triage/build views, and read-only overlay preview shell.

## Run
```powershell
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:
```powershell
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-helper``native/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
```powershell
npm run lint
npm test
npm run build
npm run scan:native:replay
npm run package:offline-check
npm run acceptance:offline
```
`scan:native:replay` only reads existing `scan-results.json`; it does not start
Genshin or send input. `package:offline-check` builds and verifies the unpacked
Windows app without launching it.
`acceptance:offline` is the full non-live gate: cleanup/helper safety tests,
TypeScript, all unit/eval tests, saved 20/50/100 validation, a fresh packaged
build, package verification, dependency audits, and `git diff --check`.
## 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.
