A fetch wrapper (raw-http-logging.ts) that captures byte-faithful .http request/response pairs for wire-level debugging of provider rejections, unlike the AI SDK-structured JsonRequestLogger view. Opt-in and dynamic: active while the configured raw-http/ directory exists (late binding, checked per chat call — mkdir mid-session to enable), or always-on via PA_RAW_HTTP_LOG_DIR. Credential-bearing header values are redacted; bodies are always byte-for-byte. All logging errors are swallowed so capture can never break a request. Wired into every AI SDK-backed model client (OpenAI, Anthropic, DeepSeek, Gemini, Vertex, Ollama, OpenRouter, Posit AI, Snowflake, Bedrock), composing with existing custom-fetch wrappers.
Look up node:fs lazily via process.getBuiltinModule instead of static node: imports so the module can be bundled into the Positron webview frontend (which shares chunks with the model clients). Outside Node, logging is simply disabled.

Adds a fetch wrapper (
raw-http-logging.ts) that captures byte-faithful.httprequest/response pairs for wire-level debugging of provider rejections — the AI SDK-structuredJsonRequestLoggerview in the monorepo shows the SDK's interpretation of a call, not the actual bytes on the wire, which is exactly what you need when a provider returns a 400 you can't explain.Behavior
raw-http/directory exists — late binding, checked per chat call, so you canmkdirmid-session to enable capture without a restart.PA_RAW_HTTP_LOG_DIRturns it on unconditionally.node:fsis looked up lazily viaprocess.getBuiltinModulerather than a staticnode:import, so the module can be bundled into the Positron webview frontend (which shares chunks with the model clients). Outside Node, logging simply disables itself.Wired into every AI SDK-backed model client — OpenAI, Anthropic, DeepSeek, Gemini, Vertex, Ollama, OpenRouter, Posit AI, Snowflake, Bedrock — composing with each client's existing custom-fetch wrappers rather than replacing them.
Consumer
Needed by posit-dev/assistant#2015, which pins this branch and adds the per-deployment
raw-http/log directories plus therawHttpLogging.mdmemory-bank doc. That PR can't merge until this one does.🤖 Generated with Claude Code
