feat(provider): route Veryfront Cloud models by wire surface - #4536
Conversation
…from the resolution logic Move the seven catalog tables out of model-catalog.ts into a data-only module, model-catalog.data.ts. model-catalog.ts imports them and keeps every function and every export unchanged: same names, types, values, and model order. A data module with no logic can be produced by a generator later without touching the package's synchronous public API. A test asserts the data module exports no function values, so logic cannot move back into it. Refs veryfront/veryfront-issue-inbox#1562
The chat model entries were frozen only as a side effect of model-catalog.ts loading and mapping over them, so importing the data module on its own returned mutable entries. Freeze every entry where it is declared, and pin it with a test that imports only the data module.
…ection The catalog data module is a table of same-shaped records, which CPD reports as the file duplicating itself (16% on new code). A test already fails if the module exports a function, so the exclusion cannot hide duplicated logic. The file stays in sonar.sources, so bugs and smells remain visible.
…g model Capture, for every model in the catalog and for every accepted vendor alias, the gateway base URL, the telemetry system attribute, the tool profile, the wire route the request is sent to, and the provider attribute on the built model. The table is a golden record taken before the routing refactor that follows, so any change to an emitted URL or attribute shows up as a diff in this file. Refs veryfront/veryfront-issue-inbox#1571
The gateway path, the request builder and the error envelope were each chosen from a closed list of provider names, so a provider the package does not list was unreachable until the package was edited and released. Route on the wire surface a provider declares in the catalog data instead. The data now carries, per provider, the surface its gateway endpoint speaks and whether it implements that surface natively; the gateway path is composed from the surface's API version, and the model builder, the OpenAI-compatible error classification and the OpenAI request builder all branch on the surface. A provider on the OpenAI surface that the catalog does not list resolves to a path of the same shape and uses the OpenAI-compatible transport with no code change. The emitted URLs, wire routes and telemetry attributes of every listed model are unchanged, which the routing golden test pins. Public types widen and keep their names: VeryfrontCloudProviderId and ProviderKind accept any provider string while the listed ones still autocomplete. Unknown providers, models and capability keys degrade rather than throw. The one deliberate failure is a surface this package builds no request for, which raises a typed error naming that surface.

Automated review — score: 78/100Solid, well-tested refactor that replaces name-based provider switches with data-driven wire-surface routing; a couple of design points worth a second look before merge. Strengths
Concerns
Not blocking, but I'd want the first concern (default OpenAI-compatible classification for unknown providers) either confirmed as intentional with a comment/test, or tightened so an unlisted, non-OpenAI-compatible provider doesn't silently get OpenAI-shaped error parsing. Generated by Claude Code |

Replace ReadonlyMap-typed Map instances with frozen arrays of entries. ReadonlyMap only enforces immutability at the TypeScript type level; a caller that casts the Map can call set/delete/clear and corrupt process- wide routing tables. Exporting frozen plain-data arrays removes the mutable Map entirely from the public data surface. model-catalog.ts builds private Maps from the frozen arrays for O(1) lookups. Export names are unchanged; types of VERYFRONT_CLOUD_PROVIDER_ALIASES and VERYFRONT_CLOUD_MODEL_TRANSPORT_CAPABILITIES change from ReadonlyMap to ReadonlyArray of frozen tuples. Extend model-catalog.data.frozen.test.ts: remove the Map special case (no Maps remain), add two tests that assert push/index-assign throw TypeError at runtime on both arrays.

The routing golden record read environment state and replaced the shared fetch, which puts a colocated unit test outside the semantic unit boundary and fails the audit. Split it: gateway-routing.test.ts keeps only pure resolution (the per-model routing table, the alias base URLs, the degradation of an unlisted provider, and the typed error for a surface with no request builder), and the two cases that need bootstrap state and a mocked transport move to provider.test.ts, which already carries that disposition. Every assertion is kept, so the audit inventory does not grow. Also state the assumption behind error-envelope classification: a provider the catalog does not list resolves to the default wire surface and is read on the OpenAI envelope, which classification only applies to fields it actually finds. Two cases pin it, one for an unlisted provider and one for the surfaces that differ. KnownVeryfrontCloudProviderId stays out of the public barrel; its doc comment now says why.

Accepting a vendor the package does not list only helped where model IDs were parsed by the new resolver. Three paths still consulted the fixed alias table, so a vendor that resolved in isolation failed in real flows. - `getVeryfrontCloudProviderFromModelId` now parses the same provider segments the gateway routes, so hosted and delegated runs, which install it as their provider resolver, no longer fail before the run starts. It still rejects an ID with no usable provider segment. - Gateway model-ID normalization prefixes any routable provider segment, so context compaction reaches the gateway instead of the global provider registry. The unsupported-model exception is unchanged. - The OpenAI-compatible model pins `chat-completions` on every construction path. Left unset, a reasoning-style model ID or a hosted tool selected the Responses runtime, which a vendor that speaks only the chat surface does not serve. Native behaviour is untouched. Every model ID that routed before routes the same way; the golden routing record is unchanged and the public export names are unchanged.

Review round: closed the gap between "a vendor the package does not list resolves" and "it actually runs". Pushed as 9d31eda, on top of a866015. Three code paths still consulted the fixed alias table:
One behaviour change beyond the unlisted case: listed non-native vendors on that surface were on the adaptive runtime, so a hosted tool switched them to the Responses surface as well. They now get the same clear failure instead. Each finding has an end-to-end test that I verified fails against the pre-fix sources: the prepared hosted execution options resolving an unlisted vendor, compaction normalising an unlisted vendor model ID, and two provider tests for the transport (a reasoning-style ID and a hosted-tools case). The golden routing record is unchanged and every name exported from Verification: |

Review follow-up on the vendor routing change. - `veryfront-cloud` is now a reserved provider ID. A doubly prefixed model ID resolved to a provider named after the prefix and produced a gateway path pointing back at the gateway; it throws again. The early return for a singly prefixed ID is unchanged. - A hosted tool on a vendor that speaks only the chat completions surface now fails with a message naming that vendor and its surface, instead of one that reads as a limit of the OpenAI runtime. The OpenAI provider takes the reason from its config and keeps its own message when no caller supplies one. - The two public prefix helpers document their contract: call them only once this backend is chosen, because they prefix any well-formed vendor segment. A typo in a well-formed segment fails at the gateway rather than locally, which is recorded as a known limitation. Verified what the pinned transport replaced: a hosted-tool request on a listed chat-surface vendor previously went to the responses endpoint on that vendor's own gateway path, which that surface does not serve, so the pin turns a remote failure into a clear local one. Tests cover the listed vendors and an unlisted one.

…ds with a function tool
The recorded call context dropped reasoning for any provider on the OpenAI
wire surface whose model ID matched an OpenAI model that suppresses reasoning
alongside function tools. That capability is recorded for OpenAI's own
models; another provider on the same surface builds its request without it,
so the context recorded { enabled: false } while the request still carried
reasoning_effort. The suppression now applies to OpenAI's models only.

New tables only:model-catalog.data.tsstays data with no logic, and every entry stays frozen where it is declared.shared.tsis gone. The gateway path is composed from the shared prefix, the provider ID and the API version of its surface.provider-http.ts, and the OpenAI request builder inmodel-call-context-request.tsall branch on the surface. No provider name is left in any of those three routing decisions.VeryfrontCloudProviderIdandProviderKindwiden toKnown | (string & Record<never, never>): listed providers still autocomplete, any other provider string is accepted.Why
A provider could only be reached when this package already knew its name, in a type union, a path map, a
switchand several string checks. All of those encode the same fact: which wire format the provider speaks. That fact now lives in the data once, so a provider on an already supported wire format works without a package release.How verified
