- add shared `EnsureResponsesUsageDetails` helper to patch `usage` objects with:
- `output_tokens_details.reasoning_tokens = 0`
- `input_tokens_details.cached_tokens = 0`
- for both plain JSON and SSE `data:` frames, including multi-line frames
- apply the helper to OpenAI Response format outputs in non-stream and stream paths across executors/plugins so translated payloads consistently include required usage details
- update websocket/completion payload builders to emit default `usage` detail fields for prewarm/finish responses
Closes: #4985
- Propagate pending terminal errors when image/response data streams close, emitting `error`/`failed` SSE events (or HTTP error responses when no stream started) instead of dropping them.
- Sanitize and normalize streamed terminal errors before writing, and reuse normalized errors for cancellation.
- Improve SSE parsing/frame handling for multiline and cross-chunk payloads, prioritize payload/event-level failures, and avoid mutating emitted frame buffers by cloning chunks before queueing.
Closes: #4904
- Added a plugin refresh-compat executor wrapper that forwards normal OpenAI-compat execution paths while routing `Refresh` to plugin `AuthProvider`/Home refresh logic.
- Updated refresh lookup to use the effective executor key from auth metadata so namespaced compatibility providers can resolve their refresh executors correctly.
- Changed OpenAI-compat registration to wrap built-in executors with the plugin-refresh wrapper when a matching plugin auth provider exists, while preserving bare executors otherwise.
- Made `OpenAICompatExecutor.Refresh` fail fast for OAuth-style credentials (with refresh tokens) instead of silently returning unchanged auth.
Closes: #4719
- Add `is-compat` support to OpenAI compatibility model config, capabilities, hashing, and example config.
- Propagate `IsCompat` through API-key model resolution and switch OpenAI-compat executor translation to compatibility-aware routing.
- Keep Claude assistant thinking content in compatibility mode while keeping default behavior unchanged when `is-compat` is disabled.
Closes: #4776
- Track terminal `[DONE]` state in translator and ignore all subsequent SSE payloads
- Stop OpenAI-compatible stream processing once `[DONE]` is received, only emit synthetic done when missing
- Add tests covering translator and executor behavior to prevent post-DONE trailing chunks from being forwarded
Closes: #4783
- Add OpenAI-compat executor-time normalization for `tool` message content, converting non-string tool results to plain text and replacing image parts with a clear unsupported marker for models configured with text-only `input-modalities`.

- Update config example to document `[text]` `input-modalities` for upstreams that reject multimodal tool-result content.

All streaming executors use bare channel sends (out <- chunk) inside goroutines
that process upstream SSE responses. When the downstream consumer disconnects
(client timeout, network drop, etc.), these sends block indefinitely, causing
the goroutine and all associated resources (HTTP response body, scanner buffers,
translation state) to leak permanently.
Over time, leaked goroutines accumulate monotonically, leading to RSS growth
from ~30MB to 3.7GB+ and eventual OOM kills on resource-constrained VPS hosts.
Fix: Replace all bare 'out <- ...' sends with:
select {
case out <- ...:
case <-ctx.Done():
return
}
This ensures goroutines terminate promptly when the request context is canceled,
allowing GC to reclaim all associated resources.
Affected executors (9 files, 36+ send sites):
- antigravity_executor.go (5 sites)
- gemini_cli_executor.go (6 sites)
- gemini_vertex_executor.go (6 sites)
- aistudio_executor.go (4 sites)
- gemini_executor.go (3 sites)

Closes: #3060#3059#2977
- Replaced all instances of `bytes.Clone` with direct references to enhance efficiency.
- Simplified payload handling across executors and translators by eliminating unnecessary data duplication.
Update ApplyThinking signature to accept fromFormat and toFormat parameters
instead of a single provider string. This enables:
- Proper level-to-budget conversion when source is level-based (openai/codex)
and target is budget-based (gemini/claude)
- Strict budget range validation when source and target formats match
- Level clamping to nearest supported level for cross-format requests
- Format alias resolution in SDK translator registry for codex/openai-response
Also adds ErrBudgetOutOfRange error code and improves iflow config extraction
to fall back to openai format when iflow-specific config is not present.
Refactored `applyPayloadConfig` to `applyPayloadConfigWithRoot`, adding support for default rule validation against the original payload when available. Updated all executors to use `applyPayloadConfigWithRoot` and incorporate an optional original request payload for translations.
Expose thinking/effort normalization helpers from the executor package
so conversion tests use production code and stay aligned with runtime
validation behavior.
When using OpenAI-compatible providers with model aliases (e.g., glm-4.6-zai -> glm-4.6),
the alias resolution was correctly applied but then immediately overwritten by
ResolveOriginalModel, causing 'Unknown Model' errors from upstream APIs.
This fix skips the ResolveOriginalModel override when a model alias has already
been resolved, ensuring the correct model name is sent to the upstream provider.
