ComfyUI custom-node package that fetches node descriptors from an
RNP/1 (Remote Node Protocol v1) server and exposes them as native V3
nodes inside ComfyUI.
Includes:
- Manifest + capability handshake, ETag-conditional object_info fetch
- Sync execute_remote and async _run_async_polling flows via
comfy_api_nodes.util.client.poll_op_raw
- Image / mask / audio / video envelope encode + decode
- Presigned upload helper for >8 MiB inputs
- Tier 3:
* TASK_LOST detection + idempotent resume — survives an RNP server
restart mid-task
* SERVER_BUSY / MAINTENANCE 503 envelopes treated as rate limits
with Retry-After honoring and friendly per-second progress text
* Out-of-band url_fetch for URI-only output envelopes per the
descriptor's remote.url_fetch policy
* Per-poll auth refresh so long-running tasks pick up rotated tokens
Pairs with Comfy-Org/comfy-rnp-server (private) as the reference
server implementation.
