ArasanEmbedded 1.2.0

Highlights

• Refreshes the vendored Arasan snapshot to upstream 95e90f5cc2507564f99eaef420795809c0ee4781 (v26.0-4-g95e90f5c), covering the Arasan 26.0 release metadata and documentation plus four subsequent search updates.
• Preserves the embedded stream-input adjustment and the package-owned initArasanEmbeddedGlobals() entry path; upstream initialization, cleanup, the required 4 MiB engine-thread stack, Fathom, and the bundled NNUE remain unchanged.
• Advances the package API-compatibility baseline to the prior v1.1.0 release.

Compatibility

• Public package API remains source-compatible with v1.1.0.
• This remains a source-only Swift package release for Apple arm64 platforms; no binary artifacts are attached.
• SwiftChessDemo consumed the exact release checkout through a disposable local package override. Arasan-vs-Arasan completed six live plies in both the iPhone simulator and an attached iPad Pro M4.

Validation

• Scripts/validate.sh
• Debug and Release builds
• 55 normal tests and 55 Thread Sanitizer tests
• CLI smoke, constrained-stack startup, invalid-input checks, and five-search soak
• iOS simulator and generic-device builds
• API compatibility against v1.1.0
• Clean committed-source archive and license validation
• SwiftChessDemo Arasan integration tests: 2 passed
• SwiftChessDemo six-ply Arasan-vs-Arasan UI regression: simulator and physical iPad passed
