Revision history for Cavil::Matcher

1.00   2026-07-22
        - Initial release: the next-generation license pattern matcher for Cavil.
        - Segmented, incrementally-updatable index: adding or removing a pattern no longer
          rebuilds the whole compiled cache (base + append-only delta segments + tombstones).
        - Versioned, CRC-checksummed, fully-validated on-disk segment format (no unchecked
          reinterpret_cast); corrupt or hostile segments are rejected, never mis-read.
        - Segments are memory-mapped read-only and queried in place, so index workers on a host
          share one physical copy instead of each materialising its own.
        - Pure-Perl manifest / segment lifecycle (Cavil::Matcher::Index, ::Manifest); a small,
          frozen C++ core (tokenizer, scan, SpookyV2 hashing) kept bit-for-bit compatible with
          Spooky::Patterns::XS, so no database migration is needed to switch engines.
        - Hardened against arbitrary input (binaries, malformed samples): never crashes.
        - 100% statement/branch/condition coverage of the Perl surface; developer-only
          differential tests against the previous engine in xt/.
