- Replace LLMError { module, method, reason } wrapper with a flat tagged
union: BadRequest, Authentication, PermissionDenied, NotFound, RateLimit,
QuotaExceeded, ContentPolicy, ContextOverflow, ServerError, APIError,
ConnectionError, TimeoutError, MalformedResponse, NoRoute.
- Delete the provider-error LLMEvent: streams carry output only and every
failure exits through the typed error channel.
- Add one shared classifyApiFailure classifier used by the HTTP executor,
protocol stream errors, and the AI SDK adapter so all routes classify
identically (including OpenAI in-stream rate_limit_exceeded and
internal_error codes).
- Enforce a terminal contract in LLMClient.stream for every route: EOF
without finish and output after finish fail as MalformedResponse.
- Classify AI SDK failures properly in core/aisdk.ts instead of collapsing
to UnknownProvider; preserve status, headers, body, and retry-after.
- Simplify the session runner: drop held-back overflow events, key overflow
recovery off LLM.ContextOverflow, retry RateLimit | ServerError |
ConnectionError | TimeoutError.
- Map new tags in toSessionError (provider.context-overflow,
provider.timeout, provider.not-found).
