Core features: - Class 1 T.30 protocol: full send/receive implementation - HDLC: DLE-stuffing, FCS strip, USR5637 bit-reversal handling - T.4 MH encoder/decoder (1728px A4 standard) - Document pipeline: PDF (Ghostscript), PNG, TIFF input - Width clamping: US Letter 1734px → 1728px fax standard - Cover page: CJK rasterization (TW/CN/JP/EN), TIFF + HTML output - OCR verification: Tesseract 5 with eng+chi_tra, CJK space-tolerant - API server (axum): health, send, jobs, cover, retry, cancel - Background worker: auto-poll queue, speed fallback, retry policy - Modem detection, pool management Real-world test results (2026-07-23): - V90 → 25153038: 4 pages, V.17 12000 bps, 2:33 ✅ - USR5637 → 25153038: 4 pages, V.17 12000 bps, 2:26 ✅ - Both faxes confirmed received on remote machine Tested: loopback (100% pixel match), multi-page, all input formats, cover pages, OCR verify, API endpoints, worker processing. 13 unit tests pass, 0 new clippy warnings.
