The Responses to Chat Completions bridge mapped both the instructions field and role developer items to system messages. Codex always sends both, and also injects developer notices mid-conversation when switching models, so the forwarded request contained consecutive leading system messages and mid-conversation system messages. Strict Qwen-family upstreams reject this with HTTP 400 "System message must be at the beginning."
Leading system/developer messages are now merged into a single leading system message, and later system/developer messages are downgraded to user so the content is preserved without violating upstream role ordering.
Real Ollama Cloud 429s are driven by ollama.com usage windows, not by
response headers that OpenAI/Anthropic/CN rate-limit parsing understands.
Handle them separately: apply a never-shortening temporary cooldown first,
then schedule an async probe that learns the true usage-window reset point
with a controlled, coalesced per-api_key refresh.
- ratelimit_service: route real Ollama Cloud usage accounts to a dedicated
429 path before the CN-provider branch.
- ollama_cloud_usage: add a background probe coordinator (started in Start,
waited by Stop) that fans out model-429 probes to one controlled refresh
per api_key group, reusing the recent group snapshot for coalesced members.
- repository/account_repo: add SetRateLimitedIfUnchanged, a write-back CAS
counterpart to ClearRateLimitIfObserved, so an async reset never overwrites
a newer 429, an admin clear, a re-armed generation, or a key/state change
observed by another writer between read and write.
- wire: inject OllamaCloudUsageService into RateLimitService.
Tests: unit tests for service and repository pass; targeted race tests pass;
build and vet clean; git diff --check clean. The CAS integration test compiles
but is not run (no Docker available).
- Fix test assertion target location for whereItems prefixItems
- Support const keyword normalization to enum and infer scalar type
- Infer scalar type for enum-only schema to prevent object reason injection
- Recursively clean properties and items after anyOf/oneOf merge
- Ensure empty prefixItems is safely deleted
- Handle JSON Schema Draft 2020-12 prefixItems (tuple arrays) by converting to a best-match items schema
- Ensure array schema always defines a valid items schema to prevent Gemini 400 'missing field: items.items' error
- Fix recursive traversal when a schema defines both properties and items
- Add comprehensive unit test cases for tuple and array schemas
Fixes#7061
monitorProviders and probeCapableProviders were missing
MonitorProviderMiniMax even though the constant, adapter, ent schema and
error message all already included minimax, so provider=minimax was
rejected by validateProvider.
Return the updated account alongside partial refresh warnings so the admin UI can keep its state current and tell operators when project ID retrieval must retry.
