Testing

The suite runs against .parc archives and uses the C sources in reference/freearc-0.67/Compression/ as codec oracles. FreeArc is not needed to use PArc.

• tests/cli.sh: smoke test for all 10 commands, options and exit codes.
• fixes.sh needs sudo for full-disk, FAT32 and symlink tests.
• Codec tests compare against FreeArc C decoders; LZMA tests also compare against liblzma.
• Fuzzing: 100 corrupted variants must never crash or hang.
• t verifies independent blocks in parallel (workers limited by PARC_THREADS); results and exit codes are the same as the serial path.
• Without -s, large archives use automatic 64 MB (levels 1–3) or 32 MB (levels 4–9 and -mx) solid blocks; small archives still use one block.
• x/e decode independent blocks in parallel to temporary files and then write sequentially, preserving order, prompts, links and errors. Temporary space is bounded by the decoded size; archives with more than 2 GB decoded use the serial path.
• -mx (PPMd/LZMA) and -mxx (CM) round-trip, damage and encryption cases are covered by tests/cm.sh; both decode in parallel.
• tests/grzip.sh checks that large BWT blocks use the adaptive l64/h22 LZP mode and small blocks keep the fast parameters.
• tests/bcj2.sh round-trips the experimental -mbcj2 filter on x86 markers, random bytes and empty input.
