• deps: update dependency @typesafe-ai/sdk to v0.7.0 (#208) (dfaa3f8)

Dependencies

These are the lowest versions the 1.1.0 packages require. If your project references one of them at a lower version, raise it, or the restore fails with NU1605:

• Minos.NET:
  • ZeroAlloc.Resilience 3.3.4, from 3.3.3;
  • ZeroAlloc.Results 1.4.2, from 1.4.1;
  • ZeroAlloc.Validation 2.3.2, from 2.3.1.
• Minos.NET.SystemOne:
  • ZeroAlloc.Rest 3.3.3, from 3.3.2;
  • ZeroAlloc.Rest.SystemTextJson 3.3.3, from 3.3.2;
  • ZeroAlloc.Results 1.4.2, from 1.4.1.

The @typesafe-ai/sdk update under Bug Fixes only touches the benchmark harness; no package changed.

⚠ BREAKING CHANGES

• core: DecisionClientMetadata.Endpoint now includes the path, so cache keys change and a distributed cache starts cold.
• core: [Criteria] is now [Criterion].
• core: The built-set EvaluateAsync overloads return QuestionSetAnswers.
• core: Named arguments Definition: and State: become definition: and state:.
• core: Use TryGetString instead.
• core: QuestionAnswer.Value is now Probability for a Noul and Expected for a Score.
• core: Choice, Score, KeyedChoice and KeyedScore can no longer be constructed directly; test through a fake IDecisionClient.
• core: DecisionResponse.Provider is now UpstreamProvider.
• core: DecisionUsage.InputTokens and OutputTokens are int?, and Usage is set when any count or the cost is reported.
• core: DecisionCapabilities.Images and ModelListing, and their configuration keys, are now SupportsImages and SupportsModelListing.
• systemone: SystemOneClient, SystemOneClientOptions, SystemOneClientServiceBuilder and AddSystemOneClient are now SystemOneDecisionClient, SystemOneDecisionClientOptions, SystemOneDecisionClientServiceBuilder and AddSystemOneDecisionClient.
• systemone: SystemOneDefaults.ApiKeyEnvironmentVariable and BaseAddressEnvironmentVariable are now TypeSafeApiKeyEnvironmentVariable and TypeSafeBaseAddressEnvironmentVariable.
• systemone: SystemOneResponse.Provider is now UpstreamProvider; the wire name is unchanged.
• systemone: Callers built against ListModelsAsync recompile.
• systemone: A malformed raw SystemOneRequest throws ArgumentException before sending, and one with no Model sends the client's configured model instead of jev-latest.
• caching: Remove using Minos.Caching and using Minos.RateLimiting.
• caching: Expiration and LocalCacheExpiration above 365 days throw ArgumentOutOfRangeException.
• caching: A call on a disposed caching or rate-limiting stage throws ObjectDisposedException.
• openai: Registered OpenAI and System One clients wait on the container's TimeProvider when one is registered.

Features

• caching: DecisionCacheOptions.UseDistributedCache turns the distributed level off (91cc456)
• core: add GetRequiredService to DecisionClientExtensions (91cc456)

• systemone: accept a raw usage object with one token count missing (91cc456)
• systemone: validate a raw request and send the client's model when it names none (91cc456)
