Add Comfy-Usage-Source header to all CLI API requests - #932
robinjhuang wants to merge 5 commits into
Conversation
The header was only attached to the ComfyUI/cloud client, `comfy run`'s /prompt submit and `comfy generate`. Builder, deploy, registry, OAuth, jobs, transfer, cloud_http and the local liveness probes sent nothing, so that traffic was indistinguishable from other clients server-side. Define USAGE_SOURCE_HEADERS once in comfy_cli/http.py and attach it in the shared request_json / build_authed_request helpers (covering every builder and deploy call) plus each remaining direct call site to a Comfy-owned host. Third-party hosts (GitHub, PyPI, model hosts, pre-signed storage URLs, telemetry) are deliberately left without it.

Strip Comfy-Usage-Source on download redirects.
_stream_http_one adds Comfy-Usage-Source to the request. _DownloadRedirectHandler does not remove it because _AUTH_HEADERS_TO_STRIP lacks comfy-usage-source. The header can therefore reach the signed storage URL.

Prevent attribution-header forwarding across third-party redirects. Both request paths add Comfy-Usage-Source and use clients that follow redirects. A cross-host redirect can therefore send the header to a host outside the scope documented in comfy_cli/http.py.
