Highlights

  • Refreshes the vendored Arasan snapshot to upstream d507b7cc583c1f0a4d02a794384b6fce2947e1a1 (v26.0-18-gd507b7cc), including the upstream fix for issue #71.
  • Updates the bundled network to arasanv8-20260906.nnue while preserving the existing embedded stream-input adjustment, package-owned global initialization, Fathom revision, and 4 MiB engine-thread stack.
  • Enables libc++ debug hardening and adds a depth-8 regression that reproduces the former invalid std::clamp bounds path.

Compatibility

  • Public package API remains source-compatible with v1.2.0.
  • This remains a source-only Swift package release for Apple arm64 platforms; no binary artifacts are attached.

Validation

  • Scripts/validate.sh
  • Debug and Release builds
  • 56 normal tests and 56 Thread Sanitizer tests
  • Depth-8 regression coverage for upstream issue #71
  • 36-position Lichess tactical regression suite at depth 8
  • CLI smoke, constrained-stack startup, invalid-input checks, and five-search soak
  • iOS 27 simulator and generic-device Release builds
  • API compatibility against v1.2.0
  • Clean committed-source archive and license validation

The optional external Syzygy asset test was not rerun because the tablebase integration and Fathom revision are unchanged.
