Iperbit-HTC3 Iperbit HTC3-LR v1.1 introduces a deterministic streaming entropy codec implemented in C and designed for low-RAM environments. This release provides a reference decoder capable of reconstructing canonical Huffman tables from a packed container format and performing fully deterministic streaming decode without dynamic memory allocation. Key properties: Deterministic decode (identical input → identical output) Streaming operation with minimal memory footprint Structural integrity validation (all versions) Optional CRC32 enforcement (container version ≥ 2) Explicit failure semantics on malformed input The container format includes canonical tables, raw length metadata, and compressed payload. Version 1 performs structural validation only, while version 2 enforces CRC32 integrity verification. Reference performance (GCC -O3, Windows x64, MinGW64): ~32 MB/s decode throughput ~49.8% compression ratio (payload/raw) on UTF-8 JSON dataset This implementation is intended for embedded, edge, and constrained systems where predictable memory usage and deterministic behavior are required.
