koel_core 1.1.1

AG-UI protocol kernel for Dart — events, errors, pipeline, reducer, JSON Patch.

1.1.1

• FIX (packaging): republish with the generated sources (*.freezed.dart, *.g.dart) included in the archive. .gitignore excluded them from the 1.1.0 upload (dart pub publish honors .gitignore when no .pubignore exists), so every part directive pointed at a missing file and the package was uncompilable for hosted consumers. Generated files are now committed to git and gated by publish-dry + the codegen-drift CI lane. No API changes — ChatSession.regenerate() / ChatSession.updateState() ship unchanged from 1.1.0.

1.1.0

• NEW: ChatSession.regenerate() — regenerates the answer to the last user turn with CopilotKit reloadMessages parity: truncates the committed transcript back to (and including) the last user message (original id preserved for server-side dedupe-by-id history merges), clears in-flight transients (pendingMessage, pendingToolCalls — setMessages replace-the-transcript semantics), and re-runs the agent without appending a new user message, so the old answer is replaced, not duplicated. No-op when the transcript has no user turn. Like send(), it does not guard against an in-flight run — callers gate on their own streaming state.
• NEW: ChatSession.updateState(Map<String, dynamic> patch) — shallow-merges a patch into the shared agent ChatState.state mid-session and re-emits, so the next run carries it in RunAgentInput.state without recreating the session. Mirrors CopilotKit agent.setState({ ...agent.state, ...patch }).
• INTERNAL: the run machinery shared by send() and regenerate() is extracted into a private _run(); send() behavior is unchanged.

1.0.0

First stable release. The koel foundation (koel_core + koel_http + koel_lints) ships lock-step at 1.0.0, conformant to the AG-UI protocol release/2026-05-26 (commit d74e2dfc1e11bebdff419c2cbd347c811555411d).

• Protocol kernel (koel_core): the closed 28-type sealed AgUiEvent registry with the UnknownAgUiEvent forward-compat fallback, the sealed KoelError hierarchy, vendored RFC 6902 JSON Patch, the four-stage event pipeline (decode → verify → reduce → dispatch), the ChatState reducer, the interceptor chain, SessionStorage, and the KoelClient / ChatSession API.
• HTTP transport (koel_http): the framework-free SSE parser, HttpAgent native transport with cancellation propagation, chunk synthesis, connection-lifecycle hooks, and the interceptor suite (retry, auth, logging, event-trace, Sentry, PII redaction).
• Lint profile (koel_lints): the koel analysis ruleset built on the first-party analysis_server_plugin.
• Conformance: the AgUiEvent_equal structural-equality rule (byte-equal Uint8List) is finalized and pinned in koel_core/CONFORMANCE.md; the SC-1..SC-5 release gates (conformance, coverage, analyze, API stability, no vestigial code) are green.
