Gemini API returns 400 error when tools have enum constraints on integer/number types:
"enum: only allowed for STRING type"
This fix removes enum constraints for integer and number types in JSON schemas
before sending to Gemini API, while keeping enum for string types.
Fixes tools like mcp__pointer__get-pointed-element that use integer enums
for cssLevel and textDetail parameters.

Adds intelligent cache control preservation for Claude Code clients:
- New cacheControlPolicy.ts module with detection logic:
- isClaudeCodeClient(): Detects Claude Code via User-Agent
- providerSupportsCaching(): Checks provider (claude, anthropic, zai, qwen)
- isDeterministicStrategy(): Identifies priority/cost-optimized strategies
- shouldPreserveCacheControl(): Main policy decision
- Cache control is preserved when:
1. Client is Claude Code (detected via User-Agent)
2. Provider supports prompt caching
3. Request routing is deterministic:
- Single model requests (always)
- Combo with priority or cost-optimized strategy only
- Updated translator to accept preserveCacheControl option
- Updated chatCore and chat handler to propagate combo strategy
- Added comprehensive unit tests (24 tests)
Non-deterministic combo strategies (weighted, round-robin, random, etc.)
continue to use OmniRoute's managed caching strategy.

HTTP 400 "invalid argument" was triggered when OmniRoute translated tool calls
to Gemini format, because thoughtSignature was injected onto every functionCall
part unconditionally. Affects two code paths:
1. openai-to-gemini.ts — OpenAI tool_calls → Gemini functionCall
2. claude-to-gemini.ts — Claude tool_use blocks → Gemini functionCall
thoughtSignature is only valid on thinking/reasoning parts (those with
thought: true or thoughtSignature as their primary field). When present on a
functionCall part, the Gemini API returns HTTP 400 'invalid argument'.
The thinking parts that legitimately carry thoughtSignature (emitted when a
message has reasoning_content / thinking blocks) are untouched.
Regression tests (T43) cover:
- single tool call: no thoughtSignature on functionCall part (openai path)
- multiple tool calls: none carry thoughtSignature (openai path)
- thinking regression guard: thoughtSignature still on thought parts
- claude-to-gemini path: tool_use blocks produce clean functionCall parts
Fixes#724
HTTP 400 "invalid argument" was triggered when OmniRoute translated OpenAI
tool_calls to Gemini format, because thoughtSignature was injected onto every
functionCall part unconditionally.
thoughtSignature is only valid on thinking/reasoning parts (those with
thought: true). The Gemini API rejects any request where a functionCall
part carries a thoughtSignature field, returning HTTP 400.
Fix: remove the thoughtSignature field from functionCall parts. The thinking
parts that legitimately require thoughtSignature (emitted when a message has
reasoning_content) are unchanged.
Adds regression test (T43) with three cases:
- single tool call: no thoughtSignature on functionCall part
- multiple tool calls: none carry thoughtSignature
- thinking part regression guard: thoughtSignature still present on thought parts
Fixes#725
- introduce open-sse/translator/helpers/schemaCoercion.ts to coerce
numeric JSON Schema fields encoded as strings
- wire coerceToolSchemas and sanitizeToolDescriptions into translator
pipeline; ensure tool descriptions are sanitized
- inject empty reasoning content for tool calls when target is OpenAI
format
- update qwen base URL to DashScope-compatible endpoint
- extend antigravity static catalog with Gemini 3.1 pro preview models and
update Gemini model specs with preview aliases
- implement call log max cap caching with TTL; expose invalidateCallLogsMaxCache
and invalidate on settings PATCH
- add tests: call-log-cap.test.mjs and tool-request-sanitization.test.mjs;
extend tests for Windsurf integration and gemini previews
- update CLI runtime and tools to include Windsurf as a guide-only tool
- add maxCallLogs to validation schemas (settings and updateSettings)
- add Czech README (README.cs.md) to repository
In OpenAI Chat Completions streaming format, the tool call id and type
should only appear on the first chunk (tool declaration). Subsequent
argument delta chunks should only include index and function.arguments.
Including id on every delta chunk caused openai-to-claude.ts to emit
a new content_block_start for each chunk, breaking Claude Code ACP
sessions with malformed Claude-format streams.
Fixes#682

- OpenAI-to-Claude translator now maps reasoning_effort (low/medium/high/max)
to Claude's thinking.budget_tokens. Fixes clients like OpenCode sending
reasoning_effort via @ai-sdk/openai-compatible losing thinking configuration.
- Ensures max_tokens > budget_tokens for all thinking configs.
- Token health check now proactively refreshes tokens within 5 min of expiry,
regardless of the configured health check interval — addresses Qwen OAuth
token refresh failures between scheduled checks.
- Handle reasoning_details[] array (StepFun/OpenRouter format) in sanitizer and translator
- Handle 'reasoning' field alias → reasoning_content in streaming and non-streaming paths
- Cross-map input_tokens/output_tokens ↔ prompt_tokens/completion_tokens in filterUsageForFormat
- Fix extractUsage to accept input_tokens/output_tokens as alternative field names
- All 936 tests pass
- fix(translator): pass toolNameMap to translateNonStreamingResponse so Claude
OAuth proxy_ prefix is correctly stripped from tool_use block names in
non-streaming responses (was only stripped in streaming path)
- fix(validation): add LongCat specialty validator that probes /chat/completions
directly, bypassing the /v1/models endpoint that LongCat does not expose (#592)

- Reword comments that contained the token any; replace any types with typed shapes
- stream.ts: passthrough tool-call flag via local boolean (state is null in passthrough)
- Document T11 in zws_docs/ZWS_README_V8.md

- Fix Claude passthrough via OpenAI round-trip normalization
- Add detectFormatFromEndpoint() for endpoint-aware format detection
- Support raw code#state in OAuth modal for Claude Code remote auth
- Expose cloudConfigured/cloudUrl/machineId in settings API
- Switch docker-compose.prod.yml target to runner-cli
- Add 3 new tests for round-trip and detectFormat
PR: #562
T01 (P1): requested_model column in call_logs
- Migration 009_requested_model.sql: ALTER TABLE call_logs ADD COLUMN requested_model
- callLogs.ts: INSERT + SELECT updated to include requestedModel field
T02 (P1): Strip empty text blocks from nested tool_result.content
- New stripEmptyTextBlocks() recursive helper in openai-to-claude.ts
- Applied on tool_result content before forwarding to Anthropic
- Prevents 400 'text content blocks must be non-empty' errors
T03 (P1): Parse x-codex-5h-*/x-codex-7d-* headers for precise quota reset
- parseCodexQuotaHeaders() in codex.ts extracts usage/limit/resetAt
- getCodexResetTime() returns furthest-out reset timestamp for safe unblocking
T04 (P1): X-Session-Id header for external sticky routing
- extractExternalSessionId() in sessionManager.ts reads x-session-id,
x-omniroute-session, session-id headers with 'ext:' prefix to avoid collisions
T06 (P2): account_deactivated permanent expired status on 401
- ACCOUNT_DEACTIVATED_SIGNALS constant + isAccountDeactivated() in accountFallback.ts
- Returns 1-year cooldown (effectively permanent) to prevent retrying dead accounts
T07 (P2): X-Forwarded-For IP validation
- New src/lib/ipUtils.ts with extractClientIp() and getClientIpFromRequest()
- Skips 'unknown'/non-IP entries in X-Forwarded-For chain
T10 (P2): credits_exhausted distinct account status
- CREDITS_EXHAUSTED_SIGNALS + isCreditsExhausted() in accountFallback.ts
- Returns 1h cooldown with creditsExhausted flag, distinct from rate_limit 429
T11 (P1): max reasoning_effort -> budget_tokens: 131072
- EFFORT_BUDGETS and THINKING_LEVEL_MAP updated with max: 131072, xhigh: 131072
- Reverse mapping now returns 'max' for full-budget responses
- Unit test updated to expect 'max' (was 'high')
T12 (P3): Model pricing updates
- MiniMax M2.7 / MiniMax-M2.7 / minimax-m2.7-highspeed pricing added
T15 (P1): Array content normalization for system/tool messages
- normalizeContentToString() helper exported from openai-to-claude.ts
- System messages with array content now correctly collapsed to string
fix(translator): preserve prompt_cache_key when translating Responses API requests
(#517) — prompt_cache_key is an account-affinity signal used by Codex for
prompt cache routing. Deleting it from the translated request prevented full
cache effectiveness. Removed delete from openai-responses.ts and
responsesApiHelper.ts cleanup blocks.
fix(combo): escape \n in tagContent so injected JSON string is valid (#515)
— omniModel tag content used template literal newlines (U+000A) which produce
unescaped newline chars inside a JSON string value. Replaced with literal \n
escape sequences for valid JSON injection in streaming SSE content chunks.
- Replace 'any other path' with 'all other paths' in translator comment to avoid false match by the \bany\b regex in check-t11-any-budget
- Scope e2e error locator to dialog and use .first() to prevent Playwright strict-mode violations from broad page-level selectors
- Fix fallback logic: treat dialog-still-open as validation success signal
Made-with: Cursor
- Add preserveDeveloperRole option and model compat override
- Normalize developer→system in roleNormalizer when not preserving
- Translator runs normalizeRoles for Responses API with option
- UI: ModelCompatPopover with do not preserve developer toggle
- Add ZWS_README_V2 documenting cause and fix

Includes version bump — v2.6.9 — committed ATOMICALLY with all changes:
fixes:
- fix(ci/t11): Remove 'any' from comments in openai-responses.ts + chatCore.ts
(\bany\b regex counted comment text as explicit any violations)
- fix(chatCore/#409): Normalize unsupported content part types before forwarding
Cursor sends {type:'file'} for .md attachments; Copilot/OpenAI providers reject
with 'type has to be either image_url or text'. Now: file/document→text block,
unknown types dropped with debug log. Fixes claude-* models via github-copilot.
workflow:
- chore(generate-release): ATOMIC COMMIT RULE — npm version patch MUST run before
feature commits so the release tag always points to a commit with full changes
