Wist 0.1.0-alpha.3 stability

UniversalToolchain.Wist 0.1.0-alpha.3 is suitable for controlled evaluation and prototypes. It is not a stable 1.0 contract.

Reviewed first-contact surface

• WistEngine;
• the exact nine-preset catalog;
• Validate, Evaluate, Compile<TDelegate> and TryCompile<TDelegate>;
• stable CLR numeric arguments/results across isolated runtime contexts;
• structured diagnostics, typed metadata and optimization reports;
• exact public API baseline and classified deltas.

Hardening guarantees added in alpha.3

• disposed engines release collectible runtime contexts, including one-shot evaluation paths;
• implementation-owned RealNumberImpl values do not escape through object results;
• CLR numeric parameters are adapted for NumbersModule-backed presets;
• trusted CLR interop converts through explicit user-defined numeric bridges on CIL and interpreter backends;
• canonical tests enforce exact TRX counts, outcomes and per-entry timeouts;
• packaged assemblies are byte-bound to compiler outputs and presets/manifests to reviewed SHA-256 values;
• semantic preset, assembly-identity, API-delta and test-contract mutants are rejected;
• the Wist LanguagePack contains package README metadata.

Not promised

• OS/process sandboxing;
• compatibility with every future alpha;
• universal near-C# performance;
• stable generic language-authoring APIs through the Wist facade.
