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.
