…verride Add infrastructure to route LLM calls through alternative providers (e.g., Cloudflare AI Gateway) without changing the model registry. A deployment-level `LLM_PROVIDER_OVERRIDE` env var replaces the provider prefix before passing model config to OpenCode. For example, setting `LLM_PROVIDER_OVERRIDE=cloudflare` routes `anthropic/claude-sonnet-4-6` as `cloudflare/claude-sonnet-4-6` — OpenCode handles the rest natively. Changes: - shared: add PROVIDER_METADATA, ProviderId type, detectUpstreamProvider() - modal-infra: remove hard ANTHROPIC_API_KEY requirement from llm_secrets - modal-infra: 3-line provider override in sandbox entrypoint - modal-infra: refactor bridge reasoning to detect upstream provider for gateway providers (cloudflare proxying to anthropic/openai) - terraform: add llm_provider_override, cloudflare_ai_gateway_* variables and conditionally inject into Modal secrets - tests: 14 new tests covering provider override, upstream detection, and gateway reasoning options (all 899 existing tests still pass) https://claude.ai/code/session_01SfZd4jtoYjZUBXJyMNRNQ9
…Gateway Verified against OpenCode docs (https://opencode.ai/docs/providers/): - Provider ID is "cloudflare-ai-gateway" (not "cloudflare") - Env vars are CLOUDFLARE_API_TOKEN, CLOUDFLARE_ACCOUNT_ID, CLOUDFLARE_GATEWAY_ID (not CLOUDFLARE_AI_GATEWAY_*) - OpenCode config needs a "provider" section to register the gateway provider with its available models Also adds a test for non-gateway provider overrides. https://claude.ai/code/session_01SfZd4jtoYjZUBXJyMNRNQ9
