concept.md is the full design document: the objective (Python re parity plus binary/ASCII/UTF-8 modes, gigabyte-scale input, single C file), the automata-theory argument for why unrestricted backreferences/lookaround are incompatible with strict single-pass constant memory, the resulting two-engine architecture, the exact Python-mirroring naming convention, and a full comparison against POSIX regex.h for C-background readers. regexx.c/regexx.h are the v1 implementation: parser, compiler to a Pike/backtracking-style bytecode, and a single recursive backtracking engine covering the pattern syntax and operations listed in README.md, validated against CPython's own re module output (tests/), clean under AddressSanitizer/UBSan, and stress-tested (50MB simple-quantifier match, graceful failure rather than a crash on complex repeats over large input, clean rejection of every intentionally unsupported construct). Also included: examples/rxgrep.c (a small grep-like program exercising all three data modes and the substitution API), the Makefile, the MIT LICENSE, and docs/API.md, an exhaustive reference for every type, flag, and function's exact return-value and memory-ownership convention, checked against the current source and against a real CPython interpreter rather than against memory.
