Automated sync of the public Comfy Router spec,
projected from the canonical contract (internal notes stripped).
Source: cloud@2d55d96.

It lands at spec/router-openapi.yaml and is a contract of its
own — it is never merged into another vendored spec in this repo.

This is the single rolling sync pull request for spec/router-openapi.yaml. It lives
on chore/sync-router-spec, and every later change to the upstream contract
force-updates this same branch and refreshes this description with the
new source commit — so there is only ever one open sync PR for this
spec, and its diff is always the current one.

The error-type class commit described above is the one commit that
belongs here. Once a commit of yours is on this branch, the next sync
refuses to force-update it and fails, naming this pull request, so
land this pull request promptly. Push any other follow-up work to a
branch of your own.

No Router operations are currently unserved (as of cloud@2d55d96).

This note auto-refreshes while this PR is open: a change to comfy-api's
exclude list rewrites this section in place, and a change to the
PUBLISHED Router surface opens its own sync PR carrying the set as of
ITS commit. Once this PR is merged the note is a permanent snapshot —
for the current state, check services/comfy-api/drip/codegen.yaml in
Comfy-Org/cloud directly.

No code generation for this spec yet. Nothing in this repo
generates code from spec/router-openapi.yaml, so this sync has no low layer to
regenerate and the workflow that opened this pull request could not
prepare one for you.

That is not the same as nothing to do. This repo keeps a hand-written
surface coupled to this contract — its error-type class table — with
a drift check of its own, so a sync that adds an error bucket still
needs a commit here before this pull request goes green. When code
generation does land for this spec, its command is configured
upstream, in the same sync workflow that opened this PR, and this
section becomes the automatic one.

Commit that class to this branch and land this pull request once it
is green. The class cannot land separately: the drift check also
fails on a class the vendored spec does not declare yet. Your commit
is safe here — the next sync will not overwrite it; it fails instead,
naming this pull request — but every later sync for this spec stays
paused until this pull request is merged (which deletes the branch,
so the following sync starts fresh), or closed and its branch
deleted.

Summary by CodeRabbit

  • New Features

    • Added a distinct queue_backlog_full error for when too many requests are waiting in the queue, separate from synchronous concurrency limits.
    • Documented that queued submissions for models that return results directly as bytes are unavailable; use synchronous runs instead.
    • Expanded Router API documentation for queue responses, retry timing, refusal details, provider selection, metering, and request validation.
  • Documentation

    • Clarified idempotency conflicts, fallback restrictions, and replayed-header behavior.

📝 Walkthrough

Walkthrough

The OpenAPI specification documents synchronous and queued run parameters, provider selection, refusal responses, and response headers. The SDK adds the QueueBacklogFull exception and updates queue-error guidance and contract tests.

Changes

Router API and SDK contract

Layer / File(s) Summary
Run request selection
spec/router-openapi.yaml
Synchronous and queued run descriptions document provider selection, strict mode, conditioned operations, and unknown-field handling. The queued-result response documents the provider-selection contract.
Run and queue error responses
spec/router-openapi.yaml
Response mappings and error schemas document queue-specific refusals, capacity failures, validation cases, idempotency-related refusal cases, and upstream rejection details.
Response headers and replay
spec/router-openapi.yaml
The specification adds capacity, refusal-subject, and upstream-detail headers. It expands dropped-parameter and fallback-header replay documentation.
SDK queue errors and contract tests
src/comfy_sdk/router_exceptions.py, src/comfy_sdk/models.py, tests/test_exception_modules.py, tests/test_router_exceptions.py, tests/test_router_spec_contract.py, README.md, CHANGELOG.md
The SDK adds and exports QueueBacklogFull, and documents queued not_enabled and backlog errors. Tests cover error mapping and the declared credits-header lift.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 4339d

The SDK change adds a typed queue-capacity refusal without changing request dispatch, authorization or retry policy. No introduced security weakness is demonstrated. However, server enforcement of the documented credential, validation and queue-isolation guarantees could not be verified here.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The inspected SDK change affects consumers interpreting Router refusals, not a new request target or credential-bearing operation. Registering the response-side exception exposes a new typed identity but grants no additional dispatch authority.

Trust Boundaries and Controls

  • observed — Queue submission and result collection declare bearer or API-key authentication. The expanded credential contract says incompatible queued credentials are refused and that authorization-related refusals also apply on the synchronous route; it does not describe a general authorization bypass through resubmission.
  • observed — The provider-selection contract states that an alternate-provider request conflicting with a resolved bring-your-own-key credential is refused before dispatch and charging. Native-schema validation is explicitly skipped for strict alternate-provider input. Neither declaration establishes the effectiveness of upstream authorization or provider-specific validation.

Resilience and Maintainability Implications

  • observed — Retry policy remains separate from exception identity: a 429 needs a usable Retry-After to trigger automatic retry, while a 403 remains terminal. This preserves the existing failure-containment gate despite the new queue-specific subtype.
  • observed — The inspected handle lifecycle leaves server state authoritative: handles address requests by model and request ID, collection supports terminal outcomes, and cancellation is best-effort rather than a completion guarantee. This PR does not change those implementation paths; server-side ownership, concurrency and cleanup guarantees remain unverified.

The spec sync needs its coupled SDK error surface and contract guards reconciled before approval.

Comment thread spec/router-openapi.yaml
- value: request_not_found
tier: transport
meaning: The `request_id` names no request of the caller's under this model. It is the second of the two conditions the queued reads' `404` covers; the first is the `{provider}/{model}` ID resolving to no partner model, which is `model_not_found` and carries fuzzy model suggestions. It also covers the right-id / wrong-model URL the path shape refuses, and it is deliberately indistinguishable from a request in another workspace, so a probe with a guessed id learns nothing. A request that has merely aged out of its retention window is `410`, not this.
- value: queue_backlog_full

[P2] Reconcile the new queue_backlog_full bucket with the SDK error surface. This sync adds a nineteenth Router bucket, but the error registry still has eighteen entries and no QueueBacklogFull class. A queue-capacity refusal therefore falls back to generic RouterError instead of the typed exception promised by the synced contract, and the contract CI tests fail. Add and export the class, register its wire value, and reconcile the contract guards in the same change.
