The mobile receipt scanner now runs Tesseract.js in-browser by default — on-device, free, and image bytes never leave the device. AI providers (OpenAI / Claude) become a per-port opt-in for higher accuracy on hard-to-read receipts. - Lazy-load Tesseract WASM in src/lib/ocr/tesseract-client.ts (5 MB bundle dynamic-imports on first scan, not in main chunk) - Heuristic parser src/lib/ocr/parse-receipt-text.ts extracts vendor, date, amount, currency, and line items from raw OCR text - New port-scoped aiEnabled flag on OcrConfig (defaults false). Resolved flag never inherits from the global row — each port admin opts in independently - Scan endpoint short-circuits to manual-mode when aiEnabled=false so the AI provider is never invoked unless the admin has flipped the switch - Scan UI runs Tesseract first, then asks the server whether AI is enabled — uses the AI result only when its confidence beats Tesseract; network failures degrade gracefully to the local parse - Admin OCR-settings form gains the per-port aiEnabled checkbox Tests: 756/756 vitest (was 747) — +7 parser unit tests, +2 aiEnabled config tests.
