## 0.1.0

* One interface (`LlmClient`) over Anthropic's Messages API, OpenAI's chat completions
  (with each known host's fields, and the local servers') and OpenAI's Responses API,
  streamed over plain HTTP; failures by kind; `FakeLlmClient` for tests; the recording
  tool; `LlmEndpoint.onThisMachine`.
feat(llm): halkyon_llm, language models' APIs streamed over plain HTTP (ADR 0021, step 2) A pure Dart package, no SDKs, one interface (LlmClient) over Anthropic's Messages API, OpenAI's chat completions, in each known host's dialect and the local servers' (D45), and OpenAI's Responses API, stateless (D46). A model's turn keeps what its provider wants back with the tools' results: Anthropic's thinking blocks, the Responses API's reasoning items and message phase, Gemini's thought signatures. Failures come by kind, the provider's words cut and without keys. Tested on replies written from the providers' documentation, replayed in pieces of 1, 7 and 4,096 bytes; tool/record_llm.dart records real ones with a key of one's own, which the tests then run on too (D36). FakeLlmClient for the code that uses it. BSD-3-Clause, as halkyon_oidc.

docs: the assistant answering in Learn, as step 3 built it Learn's AGENTS.md describes the field with the assistants answering in it (ADR 0021, step 3): who answers, the scope, the conversation sheet and its lookups, images, private studysets' warnings, kept conversations and the tasks; and the testing trap of awaiting a finished subscription's cancel. The shared packages' READMEs name providerTermsOf and onThisMachine. Learn's README no longer says there is no end-to-end encryption, which private studysets changed (ADR 0019).
