📄 Description

ELI-5

A response header tells you which of your settings the Router had to drop when it translated your request for a different provider. Three comments in the code still described an older version of the contract: they said the spec's own declaration of that header was a bug that someone had filed against the server, and they said the header only ever shows up when you explicitly ask for another provider. The spec sync in #166 settled both points the other way — the header really is one JSON-encoded string on purpose, and an automatic retry can produce it too, even on a call that asked for nothing special. This rewrites those three comments to say what is now true. No code changes.

What changed

Comments only. git diff touches src/sdk/models.ts, src/sdk/models.test.ts and CHANGELOG.md; every changed line in the two source files is inside a comment (verified mechanically — filtering the diff's +/- lines for anything that is not //, *, /** or */ returns nothing).

parseDroppedParams TSDoc. Deleted the claim that the spec's prose and its declared schema disagree, that the declared schema is the wrong half, and that a spec defect is filed against the server's openapi.yml and would be reverted by the next sync. spec/router-openapi.yaml's RouterDroppedParamsHeader now declares type: string and its description says, in its own words, to "decode it with a JSON parser rather than splitting it on commas, because it is a single string on the wire… and each entry is a sentence carrying commas of its own". The comment now says that, keeps the example entry (moderation (fal applies its own, non-configurable safety filtering)) as the reason, and keeps the existing fallback rationale verbatim in spirit: keep a non-JSON value as ONE entry rather than guessing at delimiters, because a single entry a human can read beats two confident fragments.
RunJsonResult.droppedParams TSDoc. It named modelProvider as the only producer. The synced spec names two, both under the default strict_mode=false: an explicit model_provider translation and an automatic fallback_provider retry — which is on by default and independent of model_provider — so a call that never set modelProvider can still come back with a non-null value. The comment now says so, adds that a fallback retry's list describes THAT retry's translation rather than the primary attempt's, points at servingProvider for which provider it refers to, and spells out the null cases.
RunJsonResult.droppedParams TSDoc, review round 2 (d559e05). Three cursor-review findings on that same block, all settled by the vendored spec. (a) strictMode: true was listed unqualified as a null case; StrictMode at spec/router-openapi.yaml:888-895 says it is "only meaningful together with model_provider", and RouterDroppedParamsHeader names the automatic fallback_provider retry as an independent producer, so strictMode: true suppresses the modelProvider translation only and is not on its own a guarantee of null — the comment now says that and points at fallbackProvider for the case that is. (b) "each entry names the field and why" was unconditional, but parseDroppedParams keeps a header that is not a JSON array of strings as ONE entry holding the raw wire value, so that is now the normal case rather than a guarantee. (c) null for "translation ran and dropped nothing" holds only because the server omits the header there — a present-but-empty "[]" parses to an empty array, as models.test.ts:1746 and :1753 already assert — so callers are told to check !== null rather than truthiness. Still comments only.
First parseDroppedParams test comment. Rewritten to the same framing. The it(...) title and every expect are unchanged.
CHANGELOG. One ### Fixed bullet under [Unreleased]. The repo does log doc-comment changes (0.1.5 "TSDoc for the public API members that had none", 0.1.4 "…and doc comments updated to the new host") and src/ ships in the published package, so these comments are user-visible on hover.

RunBinaryResult.droppedParams already reads "As {@link RunJsonResult.droppedParams}" and is untouched, as is the DROPPED_PARAMS_HEADER constant's one-line comment, parseDroppedParams's body, every test assertion, and spec/.

Verification against what the spec actually says

The primary artifact here is the vendored spec as of #166 (commit 4491e4b; main has since moved past it without touching spec/router-openapi.yaml), and I read it directly rather than from the ticket's summary: spec/router-openapi.yaml:927-932 declares RouterDroppedParamsHeader with schema: {type: string}, example: '["moderation (fal applies its own, non-configurable safety filtering)"]', and a description that covers both producers ("whether the caller asked for that translation with model_provider (strict_mode=false, the default) or an automatic fallback_provider retry ran it") and the fallback-retry attribution ("On a fallback retry it names what that retry's own translation… dropped, never the primary attempt's"). Every substantive claim in the new comments is traceable to that block or to RouterFallbackProviderHeader at :938-943.

Negative-claim falsification (the capability-denial trigger) does not fire on this diff: it adds no "not supported"/"unavailable" string, no throw or deny path, and flips no test to assert a dead-end. The change is strictly the opposite direction — it documents a case (droppedParams non-null with no modelProvider) the old comment wrongly ruled out.

Provenance

Authored by: agent-work loop
Verified:
- Head d3a2dc8 (merge of main at 8096086, no conflicts; the earlier CHANGELOG.md ### Fixed conflict was resolved by keeping both bullets).
- pnpm test: 691 passed, 5 skipped, 0 failed (28 files passed, 1 skipped).
- pnpm lint, pnpm format:check, pnpm typecheck and pnpm build: clean.
- pnpm check:spec-drift: generated code is in sync, and the Router route matches the spec.
- node scripts/sync-python-surface.mjs reports parity/python-surface.json is stale relative to Comfy-Org/comfy-python-sdk@refs/heads/main. main fails the same way (CI run 37967760042 at 8096086), so the problem is in the base, not this branch. The open fix is #201, and the check is not required.
Deviations: none against the original plan. d559e05 was added on top in response to review feedback. It gets no CHANGELOG bullet of its own, because the existing [Unreleased] bullet already covers the comment it refines.

Residual

Not fixed here, and worth its own look:

src/sdk/modelRequests.ts:893-899 carries a related claim that this sync may have weakened. The comment above the queued-collect result says the two alt-provider disclosure headers "are expected to be absent on this route — the queued /requests path takes no model_provider parameter, so a queued run cannot address an alternate provider and has nothing to disclose". Post-#166 the second producer of those headers is an automatic fallback_provider retry that is independent of model_provider, so "takes no model_provider" no longer establishes "has nothing to disclose" on its own. I did not change it: the four MODEL_REQUEST* operations are not declared in spec/router-openapi.yaml at all (held upstream, and the one-way sync strips a held operation — see AGENTS.md section 2), so there is nothing in the vendored contract that says whether fallback applies to the queued route, and guessing in a comment is how this ticket's defect got written in the first place. The code is unaffected either way — it reads the headers unconditionally and returns whatever is there. Resolving it needs a statement from the Router side about queued-route fallback.
Unexercised artifact: the producer. The ticket cites router_run.go's writeRouterResult in the cloud repo as the side that json.Marshals the list. That repo is not in this sandbox and is outside this PR's repo, so I could not read it. I substituted the vendored spec, which is the contract this SDK is actually checked against, and the parser's behavior is unchanged regardless — nothing in this diff depends on the Go source being what the ticket says it is.
Unexercised artifact: the originating investigation. The comment thread that motivated this arrived as a summary; I could not open the underlying investigation to check for anything it recorded and the summary omitted. No part of this diff rests on it — every claim is re-derived from the vendored spec in this repo.
Rebase note. #157 (X-Comfy-Credits-Used) has landed and is merged in here; src/sdk/models.ts auto-merged. #164 (replayed) and #152 (Idempotency-Key on errors) are still open, and each adds an adjacent RunJsonResult field rather than touching these comment blocks.
The red sdk-parity check is pre-existing and does not come from this branch. Earlier it failed with an ExtractionError on RouterRunResult. That was fixed by #167, which is merged in here. It now fails because the Python surface snapshot is stale, and main fails identically (run 37967760042 at 8096086). This is the case AGENTS.md section 6 describes as "usually not about your branch", and #201 is the open snapshot refresh.

Summary by CodeRabbit

Documentation
- Clarified that dropped-parameter details are provided as a JSON-encoded array in a single response header, and how values are handled when the header does not match that format.
- Explained that dropped parameters can result from explicit provider translation or automatic fallback retries. For fallback results, the field reflects the retry’s translation and may be null or an empty array depending on whether any parameters were dropped.
- Updated descriptions of queued routes to clarify which provider options they omit. Parsing and header handling are unchanged.
