Closes: #6432
An attachment a translator could not represent was dropped without a word, and
a turn whose only content was that attachment went upstream as an empty
messages, parts, or input array. The model then answered as if nothing was
attached, or the upstream rejected a request that never named the attachment.
A base64 document now reaches OpenAI as a file part. A file the target cannot
receive, such as container_upload, an OpenAI file_id, or input_audio sent to
Claude, is reported by name so the route answers 400 instead of forwarding an
empty turn. Text beside it still travels.
One rule, ErrIfNothingLeft, decides when to refuse, and RegisterCheckedRequest
carries the refusal on the request envelope. Every executor that translates
checks it before calling upstream. The exported converters keep their []byte
signature, so no caller or sibling test had to change.
- Reject speech-only models (such as `grok-tts` and `grok-voice-tts-1.0`) on non-speech entry protocols to prevent invalid chat upstream routing
- Mark upstream 404 errors for xAI speech as request-scoped unless indicating model unavailability, preventing unnecessary credential rotation and model cooldowns
- Align xAI speech payload finalizer protocol with `openai` for consistent payload override rules
- Buffer and publish observed upstream usage when apply patch transformation or translation encounters an error in Meta and xAI executors
- Add stream usage buffer helpers to report failure metrics with captured upstream token usage
Closes: #6427
- Update cloaking check to retain caller system instructions at the top level when a conversation begins with multiple consecutive user messages followed by assistant turns
Closes: #6426
- Update terminal user run check in Claude cloaking logic so conversations ending with a single user turn keep caller system instructions at the top level instead of relocating them into mid-conversation messages
Closes: #6423
- Detect terminal stream chunks and avoid recording client cancellations as execution failures once completion events have been delivered
Closes: #6421
- Pre-allocate `oauthToolAliases` in Claude and Kimi executor constructors so request copies created via `ForAPIKey` reuse the same store
- Replace struct-level mutex with package-level mutex for lazy store allocation to prevent copying mutexes by value
Closes: #6401
- Retain unknown-format `encrypted_content` during reasoning signature sanitization when compatibility mode is enabled
- Continue stripping empty signatures and known foreign provider signatures in compat mode
Closes: #6399
- Record reasoning effort from finalized upstream payload after cache helper processing across execution, streaming, compaction, and image requests
Closes: #6388
- Track pending completion state in OpenAI-to-Responses translator when item output is complete and a finish reason is received
- Synthesize terminal `[DONE]` event on clean EOF when response completion is pending instead of failing the stream
Closes: #6381
- Honor `prompt_cache_options.mode = "explicit"` to suppress automatic `cache_control` insertion while preserving client-defined cache breakpoints
- Strip `prompt_cache_options` from request payloads before forwarding upstream and during token counting
Closes: #6380
Replace Codex-specific response model APIs with shared model observation and remove redundant substitution warning throttling. Consolidate repeated Antigravity context-hash rejection messages into a single request-level log while preserving rejection details across index rebuilds.
- Track terminal chunks including finish reasons, stop messages, and completion events during streaming
- Commit replay settlements and publish observed usage instead of reporting stream failure when the client disconnects after a terminal chunk
Closes: #6376
- Buffer and assemble multi-line or split JSON chunks until a valid JSON payload is formed
- Intercept upstream backend error objects during streaming and surface them as terminal errors with appropriate status codes
Closes: #6357
- Track terminal connection errors on websocket session when upstream read loops fail or receive unexpected binary payloads
- Return recorded terminal errors immediately during session activation to prevent callers from blocking indefinitely after upstream disconnects
- Reset terminal error state when configuring new connections
Closes: #6354
- Add bounded in-memory store to retain Claude OAuth tool alias mappings keyed by message ID
- Restore alias mappings for thread continuation requests omitting tool declarations, returning a request-scoped not found error when state is missing
- Record tool aliases on execution and streaming response completion
Closes: #6346
- Add `claudeMidConversationSystemMessagesAtEnd` to detect consecutive user messages ending the message array
- Append forwarded system blocks to top-level `system` payload instead of inserting mid-conversation message turns when trailing user turns are present
Closes: #6336
- Add `FlushResponse` to prefer error-aware flushing and unwrap wrapped response writers
- Bypass Gin's void `Flush` while maintaining header accounting via `WriteHeaderNow` to keep transport errors observable
Closes: #6332
- Add `PayloadFinalizer` to apply configuration rules at the final serialization barrier
- Support decoding, modifying, and re-encoding Devin protobuf business fields
- Add multipart form-data payload normalization to JSON for media payload rules
Closes: #5067
- Allow early content streaming for OpenAI formats while preserving ordering behind queued tools
- Defer thought step termination and accumulate signature fragments for OpenAI Responses format
- Flush deferred reasoning step stops when closing open stream steps
Closes: #6306
- Add ASCII pre-filter to skip expensive gjson traversals for title helper and 1h TTL checks
- Check raw bytes for target keywords before initiating full JSON walks
- Fall back to full inspection when printable ASCII Unicode escapes are detected
Closes: #6291
- Pin local date to continuity context on the first request of a session
- Reuse pinned session date during cloaked date injection across execute and stream flows
- Prevent midnight calendar date flips from invalidating conversation prompt cache prefixes
Closes: #6282
Accept historical v8 config paths and request bodies while saving the
latest canonical layout. Preserve comments on scalar updates and keep v0
saves from migrating legacy-only files unnecessarily.
Move shared Codex, Claude, and xAI provider options under upstream so
they apply consistently to OAuth and API-key credentials. Migrate
historical OAuth paths, preserve OAuth-only header scope, and expose the
new upstream management API path.
- Fall back to top-level token usage when Codex response usage contains only service tier metadata
- Propagate parsed service tier while retaining top-level token counts
- Avoid early return during stream usage observation for chunks with zero token counts
Closes: #6261
- Allow connection count slack for concurrent wave dials to prevent flakiness under load
- Assert strictly against unpooled worst case instead of fragile lower bounds on connection count
Closes: #6259
- Track cumulative usage snapshots from `usageMetadata` and `cpaUsageMetadata` across stream chunks
- Defer terminal response event emission until usage frames arrive or the stream ends
- Map `MAX_TOKENS` finish reason to `response.incomplete` status and incomplete output item states
