The Chapel HPC engine, Zig FFI layer, Idris2 ABI proofs, and all subsystems are implemented. The only remaining blocker is multi-locale testing on an HPC cluster.
-
✓ Julia extraction engine (now legacy)
-
✓ OCaml Scheme transformer
-
✓ Ada terminal UI
-
✓ RSR-compliant repository structure
-
✓ Chapel distributed processing (Config, ManifestLoader, FaultHandler, ProgressReporter, ShardedOutput, ResultAggregator, Checkpoint)
-
✓ Zig FFI layer with multi-format parser dispatch (PDF, Image, Audio, Video, EPUB, GeoSpatial)
-
✓ Idris2 ABI proofs (Types, Layout, Foreign)
-
✓ Generated C header (51 functions)
-
✓ Integration tests
-
✓ 20 processing stages with Cap’n Proto binary output
-
✓ NDJSON enriched manifests (eliminates 170M stat() calls)
-
✓ Two-level caching: L1 LMDB per-locale + L2 Dragonfly cross-locale
-
✓ Conduit preprocessing pipeline (magic-byte detection, SHA-256, validation)
-
✓ I/O prefetcher (io_uring + posix_fadvise fallback)
-
✓ Hardware crypto acceleration (SHA-NI, AVX2, AVX-512, AES-NI, ARM SHA2)
-
✓ Checkpoint and resume
-
✓ GPU OCR coprocessor (PaddleOCR/Tesseract CUDA/CPU via dlopen)
-
✓ ML inference engine (ONNX Runtime: NER, Whisper, ImageClassify, Layout, Handwriting)
-
✓ Handle attachment pattern (ML + GPU OCR wired into parse path)
-
✓ 40+ Zig integration tests covering all subsystem APIs
-
✓ Containerfile (Wolfi runtime) and Slurm job script
-
✓ Full Idris2 ABI coverage (14 types, 5 struct proofs, 51 FFI declarations)
-
✓ Checkpoint protocol compliance (all 6 SCM files populated)
-
✓ Author/copyright/license cleanup across all files
