* feat: add OpenAI format provider support Add bidirectional format conversion for OpenAI Chat Completions API, enabling fallback providers like OpenRouter, Together AI, and any OpenAI-compatible endpoint. Changes: - Add format field to ProviderConfig (anthropic|openai) - Implement request/response conversion with tool_use support - Add streaming SSE conversion via TransformStream - Update admin UI with format selector - Add 37 comprehensive tests (259 total passing) - Validate format field at API boundary Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com> * test: improve format-converter coverage to 99%+ Add tests for edge cases: non-string/non-array content, invalid JSON in stream, interleaved text+tool_calls, flush with remaining buffer, and usage in regular chunks. * chore: add Codecov configuration with relaxed thresholds Allow coverage to decrease by up to 5% and set patch target to 70% to prevent CI failures on minor coverage fluctuations. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat: test multiple Claude models in testConnection with mapping suggestions Refactor testProvider to test 4 models (Sonnet, Opus 4, Opus 4.6, Haiku) in parallel instead of a single hardcoded model. Shows per-model results in the admin UI and suggests adding model mappings when models fail without one configured. Also adds claude-opus-4-6-20250415 to CLAUDE_MODELS. * feat: add provider disable/enable toggle in admin panel Show Anthropic primary API as fixed first entry with toggle switch. Replace reorder arrow buttons with enable/disable toggles on all providers. Disabled providers are skipped during request routing. * test: add tests for provider disable/enable skipping behavior Verify disabled Anthropic primary and fallback providers are skipped during request routing, and that 502 is returned when all are disabled. --------- Co-authored-by: Claude Haiku 4.5 <noreply@anthropic.com>
…error messages, and logging format. Adjust provider configurations and enhance circuit breaker functionality. Remove DEBUG variable from wrangler configuration.
* feat: new fallback algo * docs: update documentation for circuit breaker implementation - Update CLAUDE.md with circuit breaker architecture details - Expand README.md with setup instructions - Add comprehensive testing guide - Update environment variables documentation - Add contribution guidelines - Expand runbook with troubleshooting steps Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
* feat: add structured logging and observability Implements comprehensive observability with structured JSON logging: - Add structured logger utility with JSON format output - Generate unique Request ID for end-to-end tracing - Return Request ID in response headers (X-Request-ID) - Support client-provided Request ID via header - Replace all console.log with structured events - Track latency for all provider attempts - Add 11 event types: request.*, provider.*, circuit_breaker.*, safety_valve.*, auth.*, config.* All logs include: - timestamp (ISO 8601) - level (debug/info/warn/error) - event type - requestId - structured data (provider, model, status, latency, error) Benefits: - Full request tracing via Request ID - Easy querying in Cloudflare Dashboard - Ready for Logpush to Grafana/Datadog/Sentry - Automatic tracing integration (already enabled in wrangler.jsonc) Documentation: - Added docs/observability.md with usage guide - Updated CLAUDE.md with observability section Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * fix: correct Headers type for x-request-id response header Convert Record<string, string> from cleanHeaders to Headers object before calling .set() method. * chore: update * feat: log reproducible curl command on request failure When all providers fail, emit a `request.debug_curl` log entry containing a copy-paste ready curl command that reproduces the original request to the proxy. Accessible via `npm run tail` for local debugging. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Sonnet 4.5 <noreply@anthropic.com>
Replace the health check endpoint at / with a 302 redirect to /admin, preparing for login page support on the admin panel. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add loginPage export to admin.ts that renders a standalone login form. The page validates the admin token against /admin/config, stores it in localStorage for session persistence, and redirects to the admin panel on success. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Switch admin panel fetch calls from passing token as query parameter to using Authorization: Bearer header. This is more secure as tokens in query params can leak via server logs and referrer headers. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat(rectifier): add type definitions for rectifier system * feat(rectifier): implement Anthropic API rectifier system Add automatic rectifier that detects and fixes Anthropic API request compatibility issues with third-party providers. Includes thinking signature rectification (removes thinking blocks, redacted_thinking blocks, and signature fields) and thinking budget rectification (adjusts budget_tokens and max_tokens to valid ranges). Each rectifier retries once per request to prevent infinite loops. Configurable via admin API endpoints with KV persistence.
