Closes #3411.

Summary

Adds a Cloudflare Workers AI provider, hooked up across core, docs, UI, schemas, and CI.

Cloudflare exposes an OpenAI-compatible surface for /v1/chat/completions and /v1/embeddings under the per-account base URL https://api.cloudflare.com/client/v4/accounts/<account_id>/ai/v1, so this provider sits firmly on the OpenAI-compat path and delegates to the shared openai.HandleOpenAI* handlers in the same pattern as Cerebras, Groq, etc.

The one wrinkle is that there is no global default URL that omits the account id. NewCloudflareProvider therefore returns an error when network_config.base_url is empty, rather than silently routing to a broken endpoint.

What's wired up

Provider

  • core/providers/cloudflare/cloudflare.go — Provider implementation, modelled on Cerebras. Supports chat (streaming + non-streaming), responses (chat-fallback), embeddings, list models. Everything else returns NewUnsupportedOperationError.
  • core/providers/cloudflare/cachedcontents.go — Mirrors the Cerebras unsupported-cached-content stubs so the Provider interface is satisfied.
  • core/providers/cloudflare/cloudflare_test.go — Comprehensive llmtests config gated on CLOUDFLARE_API_KEY + CLOUDFLARE_ACCOUNT_ID (skips when unset, mirroring the Cerebras test), plus a unit test that locks in the "base_url is required" contract without needing network access.

Schema + wiring

  • core/schemas/bifrost.goCloudflare ModelProvider constant added to StandardProviders.
  • core/bifrost.gocreateBaseProvider wires schemas.Cloudflare to cloudflare.NewCloudflareProvider.

Docs + config schema

  • docs/providers/supported-providers/cloudflare.mdx and docs/docs.json navigation entry.
  • docs/openapi/openapi.json and transports/config.schema.json — provider enums updated in all required spots (config provider map, fallback embedding provider enum, base provider type enum).

UI

  • ui/lib/constants/config.tsModelPlaceholders.cloudflare and isKeyRequiredByProvider.cloudflare.
  • ui/lib/constants/logs.tsKnownProvidersNames, ProviderLabels, and EmbeddingSupportedProviders.
  • ui/lib/constants/icons.tsx — Cloudflare cloud icon following the existing theme-aware pattern.

CI

  • .github/workflows/pr-tests.yml, release-pipeline.yml, and scripts/test-docker-image.shCLOUDFLARE_API_KEY and CLOUDFLARE_ACCOUNT_ID added everywhere CEREBRAS_API_KEY is wired (10 jobs total). Maintainers will need to set the matching repository secrets; without them the integration test skips cleanly.

Verification

  • go build ./... passes.
  • go test ./providers/cloudflare/... passes (TestCloudflare skips without keys; TestCloudflareRequiresBaseURL passes).
  • go test ./providers/... — all packages green except the pre-existing TestBifrostToGeminiToolConversion failure on main, which is unrelated to this change. I confirmed it fails on main before any Cloudflare commits.
  • npm run lint (UI) — 0 errors, 387 pre-existing warnings unchanged.

Notes for maintainers

The Cloudflare brand icon I added is a clean cloud silhouette in the official brand orange (#F38020). Happy to swap in the official Cloudflare wordmark from the press kit if you'd prefer — just let me know.

Tool calling on Workers AI is model-dependent; the test config keeps ToolCalls: false for the first cut. We can flip it on later for catalog entries that advertise function_calling: true.

Estimated code review effort: 4 (Complex) | ~45 minutes

Mergeability Score: 🔵 Low · up to 5f5af

The PR adds the Cloudflare provider and related configuration wiring. It is mergeable with explicit owner awareness because the OpenAPI documentation still has a bounded inconsistency around the quarterly-only reset_config field, which could mislead consumers but does not indicate a runtime or security blocker.

Confidence Score: 4/5

Safe to merge; all request paths are correct and the only finding is a misleading code comment that does not affect runtime behavior.

The double-slash URL issue raised in earlier reviews has been fixed: the base URL is stored without /v1 and per-request concatenation produces correct URLs. The account.go wiring is now complete across all three callbacks. The one remaining issue is an incorrect comment in GetConfigForProvider claiming that NewCloudflareProvider returns an error when CLOUDFLARE_ACCOUNT_ID is absent — the constructor actually accepts the resulting non-empty (malformed) URL, and graceful skipping is handled entirely by the t.Skip() guards in the test file. This does not cause any runtime failure but could mislead future maintainers.

core/internal/llmtests/account.go — the comment block in the Cloudflare case of GetConfigForProvider misstates why the test behaves correctly when CLOUDFLARE_ACCOUNT_ID is unset.

Important Files Changed

Filename Overview
core/providers/cloudflare/cloudflare.go New CloudflareProvider implementation delegating to shared OpenAI handlers. BaseURL validation, trailing-slash normalization, streaming/non-streaming paths, and all interface stubs look correct. The base URL is stored without /v1, which gets appended per-request — addressing the earlier double-path concern.
core/internal/llmtests/account.go Cloudflare wired into all three required hooks (GetConfiguredProviders, GetKeysForProvider, GetConfigForProvider). Code behavior is correct; comment in GetConfigForProvider incorrectly states NewCloudflareProvider errors when CLOUDFLARE_ACCOUNT_ID is unset — the constructor accepts the malformed URL and the skip guards in the test file handle the absent-secret case.
core/providers/cloudflare/cloudflare_test.go Comprehensive test with proper skip guards on both CLOUDFLARE_API_KEY and CLOUDFLARE_ACCOUNT_ID, plus a standalone unit test for the required-base-URL contract. Scenarios are appropriately scoped for Workers AI first cut.
.github/workflows/scripts/test-docker-image.sh The heredoc + post-processing sed approach correctly substitutes CLOUDFLARE_ACCOUNT_ID into the config URL while keeping the env.XXX literals intact. Guard on non-empty variable before running sed is correct.
core/schemas/bifrost.go Cloudflare added to both SupportedBaseProviders and StandardProviders. Placement in SupportedBaseProviders is justified: unlike other OpenAI-compat providers (Groq, Cerebras), Cloudflare enforces a required BaseURL, making it a meaningful distinct base type for custom providers that share its URL contract.
core/bifrost.go Clean wiring of schemas.Cloudflare to cloudflare.NewCloudflareProvider in createBaseProvider switch, consistent with all other providers.
core/providers/cloudflare/cachedcontents.go All cached-content interface methods return UnsupportedOperationError, matching the pattern from Cerebras and other non-Google providers.
transports/config.schema.json Cloudflare added to provider map, fallback embedding provider enum, and base provider type enum — all three locations updated consistently.
ui/lib/constants/icons.tsx Cloud SVG icon in Cloudflare's brand orange following the existing theme-aware pattern. No issues.

In @.github/workflows/release-pipeline.yml:
- Around line 224-225: The test jobs that inject Cloudflare secrets (jobs named
test-core, test-framework, test-plugins, test-api-integrations,
test-docker-image-amd64, test-docker-image-arm64) also require network access to
api.cloudflare.com:443; update each job's harden-runner configuration to add
"api.cloudflare.com:443" to the allowed-endpoints list so Cloudflare provider
tests can reach the API even when egress-policy: block is enabled (apply the
same change where similar blocks exist around the other occurrences referenced
in the comment).

In @.github/workflows/scripts/test-docker-image.sh:
- Around line 154-157: The cloudflare config's base_url currently contains a
literal $CLOUDFLARE_ACCOUNT_ID because the surrounding heredoc is single-quoted;
update the heredoc quoting so shell variables are expanded and use an explicit
variable reference (e.g., ${CLOUDFLARE_ACCOUNT_ID}) in the "base_url" value
inside the "cloudflare" object so the account ID is interpolated at runtime;
ensure you only change the heredoc quoting (to allow expansion) and the base_url
string, leaving other keys (keys, network_config) untouched.

In `@core/providers/cloudflare/cloudflare.go`:
- Line 128: Update the ChatCompletionStream handler to build its request URL
using providerUtils.GetPathFromContext(ctx, "/v1/chat/completions") instead of
directly concatenating provider.networkConfig.BaseURL+"/v1/chat/completions";
locate the ChatCompletionStream function and replace the hardcoded concatenation
with provider.networkConfig.BaseURL+providerUtils.GetPathFromContext(ctx,
"/v1/chat/completions") so it matches how ListModels, ChatCompletion, and
Embedding construct their URLs and respects context-based path overrides.

In `@docs/providers/supported-providers/cloudflare.mdx`:
- Around line 37-57: Update the Cloudflare provider MDX page to include the
required Mintlify tabs "Web UI", "API", and "config.json"; in the Web UI tab
copy the existing prose about Base URL, Max Connections, Idle Timeout and the
note about NewCloudflareProvider returning an error when network_config.base_url
is empty, in the API tab show the Authorization header format ("Authorization:
Bearer <api_token>") and required token scope, and in the config.json tab
provide a concrete JSON example that matches the transports/config.schema.json
(include fields for network_config.base_url, network_config.max_connections,
network_config.idle_timeout_in_seconds/stream_idle_timeout_in_seconds as used by
NewCloudflareProvider); validate the JSON example against
transports/config.schema.json before committing.

…verride, harden-runner allowlist

Three review fixes from Greptile and CodeRabbit on maximhq#3604:

1. .github/workflows/scripts/test-docker-image.sh — the heredoc that
   writes config.json is single-quoted (correctly, since `env.XXX`
   strings are resolved by Bifrost itself), so $CLOUDFLARE_ACCOUNT_ID
   in the cloudflare base_url was being written literally and the
   integration test would hit an invalid URL when the secret is set.
   Substitute it after the heredoc with sed using a non-/ delimiter
   so the URL slashes don't need escaping.

2. core/providers/cloudflare/cloudflare.go — ChatCompletionStream now
   builds its URL with providerUtils.GetPathFromContext, matching
   ChatCompletion / Embedding / ListModels and respecting any
   context-set path override.

3. .github/workflows/release-pipeline.yml — added api.cloudflare.com:443
   to all 4 step-security/harden-runner allowlists that already
   include api.cerebras.ai:443, so the Cloudflare integration tests
   can reach the upstream API under the egress-policy: block jobs.

Thanks for the reviews. Pushed 32bc89a addressing the actionable items:

  • test-docker-image.sh$CLOUDFLARE_ACCOUNT_ID not expanding (Greptile, CodeRabbit). The heredoc is intentionally single-quoted because the env.XXX strings are resolved by Bifrost itself, not the shell. Fixed by substituting $CLOUDFLARE_ACCOUNT_ID with sed right after the heredoc closes — non-/ delimiter so the URL slashes don't need escaping.
  • ChatCompletionStream URL construction (CodeRabbit). Now uses providerUtils.GetPathFromContext(ctx, "/v1/chat/completions") to match ChatCompletion, Embedding, and ListModels and respect context path overrides.
  • harden-runner allowlist (CodeRabbit). Added api.cloudflare.com:443 to all 4 release-pipeline.yml allowlists that already include api.cerebras.ai:443, so the Cloudflare integration tests can reach upstream under egress-policy: block.

I deliberately skipped CodeRabbit's MDX restructure suggestion (Web UI / API / config.json tabs). That pattern is used in this repo for providers with non-trivial auth modes — Azure, Bedrock, Vertex — and skipped for the simple OpenAI-compat providers Cloudflare sits next to (Cerebras, Groq, Mistral, Ollama, etc). Adopting it just for Cloudflare would be inconsistent with the cohort. Happy to add it if the maintainers prefer the broader convention.

go build ./... and go test ./providers/cloudflare/... both green on the new commit.

Keep provider allowlists consistent for Cloudflare custom-provider configs.

Cloudflare is added to ModelProvider (Line 51) and StandardProviders (Line 81), and this stack also adds cloudflare to custom_provider_config base-provider schema enums. But SupportedBaseProviders still omits Cloudflare, which can reject schema-valid custom-provider configs at runtime validation.

CloudflareProvider which leaves NetworkConfig.ExtraHeaders shared and can cause
races; update the CloudflareProvider construction to deep-copy the ExtraHeaders
map from config.NetworkConfig (e.g., create a new map, copy entries or use

the provider owns its own map instance while keeping the rest of

…ovider

Two more review fixes from Greptile and CodeRabbit on maximhq#3604:

1. Greptile (P1, confidence 3/5): every Cloudflare endpoint URL was
   constructed with a double `/v1/` segment because the documented
   base URL ended in `/ai/v1` and the provider also appended
   `/v1/...`, so live calls went to `…/ai/v1/v1/chat/completions` and
   would 404. The cause is that I diverged from the Cerebras/Groq
   convention — those providers have the base URL stop at the host
   (`https://api.cerebras.ai`) and append `/v1/...` per request. The
   fix is to stop the documented Cloudflare base URL at `/ai`,
   matching the cohort. Provider code is unchanged; only the
   documented / fixture URLs move.

   Updated:
     - core/internal/llmtests/account.go (test fixture)
     - .github/workflows/scripts/test-docker-image.sh (docker config)
     - core/providers/cloudflare/cloudflare.go (package doc + the
       constructor's error message that suggests the URL)
     - core/providers/cloudflare/cloudflare_test.go (URL the unit
       test asserts the constructor accepts)
     - docs/providers/supported-providers/cloudflare.mdx (user
       guidance + the caveat block that referenced the URL)

2. CodeRabbit (Major, outside-diff): SupportedBaseProviders omitted
   Cloudflare while StandardProviders and the
   custom_provider_config schema enums included it, so a
   schema-valid custom-provider config backed by Cloudflare would be
   rejected by the runtime allowlist. Added schemas.Cloudflare to
   SupportedBaseProviders alongside the other OpenAI-compat-friendly
   bases.

Skipped two CodeRabbit suggestions intentionally:

- Deep-copy NetworkConfig.ExtraHeaders to avoid a shared-map race.
  No provider in core/providers/* deep-copies it today (cerebras,
  groq, mistral, cohere, …); changing only cloudflare would make it
  the inconsistent one. If the race is real, it should be addressed
  repo-wide in a separate PR.
- Replace `schemas.Cloudflare` with `provider.GetProviderKey()` in
  the streaming call. Same reason — every other OpenAI-compat
  provider hardcodes its own ModelProvider in HandleOpenAIChat
  CompletionStreaming (cerebras line 168, etc.). Matching the cohort
  for now.

Pushed 230cff5e addressing the round-2 review feedback. Branch is rebased onto current dev (10 new commits incorporated cleanly).

Fixes

  • Greptile P1 — double /v1/ in every Cloudflare endpoint URL. Real bug. I diverged from the Cerebras/Groq convention where the base URL stops at the host (https://api.cerebras.ai) and the provider code appends /v1/... per request. The fix is to stop the documented Cloudflare base URL at /ai, matching the cohort. Provider code is unchanged; only the documented and fixture URLs move. Updated: test fixture (account.go), docker test script, package doc, constructor error message, unit-test fixture URL, and provider docs MDX.

  • CodeRabbit Major (outside-diff) — SupportedBaseProviders allowlist. Added schemas.Cloudflare so schema-valid custom-provider configs backed by Cloudflare aren't rejected at runtime. The schema enums in transports/config.schema.json already include it.

Skipped, with reasoning

  • CodeRabbit Major — deep-copy NetworkConfig.ExtraHeaders to avoid a shared-map race. No provider in core/providers/* deep-copies it today (cerebras, groq, mistral, cohere, etc. all use the same shallow assignment). Changing only Cloudflare would make it the inconsistent one. If the race is real, happy to follow up with a separate repo-wide PR.

  • CodeRabbit Minor — replace schemas.Cloudflare with provider.GetProviderKey() in ChatCompletionStream. Same reason — every other OpenAI-compat provider hardcodes its own ModelProvider in HandleOpenAIChatCompletionStreaming (e.g. cerebras.go:168). Matching the cohort.

  • CodeRabbit Major — Mintlify Web UI / API / config.json tabs in the MDX. Same reasoning as last round: the tabbed pattern in this repo is used by complex-auth providers (Azure, Bedrock, Vertex) and skipped for the simple OpenAI-compat ones (Cerebras, Groq, Mistral, Ollama, …) that Cloudflare sits next to. Happy to add it if maintainers prefer the broader convention.

Verification: go build ./... and go test ./providers/cloudflare/... both green on the rebased branch.

Pushed 41f09a6 for the latest CodeRabbit nit:

  • NewCloudflareProvider now TrimSpaces the user-supplied URL once up front and uses that trimmed value for both the empty check and the TrimRight("/") before persisting. Previously, " https://.../ai/ " would pass the empty check but be stored with the leading space intact, which would have broken request URL construction.
  • Added a TestCloudflareRequiresBaseURL case that constructs the provider with a whitespace-padded URL to lock in the behaviour.

go build ./... and go test ./providers/cloudflare/... green.

## Summary

Adds a `CatalogPricingOverrides` API to the model catalog's pricing override system, enabling the management UI to display which pricing overrides apply to a given model/provider row and which are present informationally (e.g. virtual-key or user-scoped overrides that can't be evaluated without a request context).

## Changes

- Introduced `CatalogPricingOverrides` struct with two distinct fields: `AppliedID`/`AppliedPatch` (the winning override under global/provider scopes only) and `Matching` (all overrides touching the model+provider, sorted most-specific-first, for informational display).
- Refactored `customPricingData.resolve` into a thin wrapper over a new `resolveEntry` method, which returns the winning `customPricingEntry` directly so callers can recover the override's identity without duplicating the precedence walk.
- Added `matchesCatalogProvider` and `matchesModel` helpers on `customPricingEntry` to support catalog-context filtering, where virtual-key/user/provider-key scopes have no runtime identifiers but should still surface informationally. Provider-key-scoped entries carry no `provider_id` and always pass the provider filter.
- Added `catalogScopeRank` to order scope kinds most-specific-first for display, independent of runtime identifiers.
- Exposed `Store.CatalogPricingOverrides` and `ModelCatalog.GetCatalogPricingOverrides` as the public entry points.
- Re-exported `CatalogPricingOverrides` from the `modelcatalog` package via the existing type alias block.

## Summary

Exposes pricing override information in the `listModelDetails` API response so the UI can display which models have negotiated or custom rates applied, and strike through only the specific cost fields that differ from the catalog baseline.

## Changes

- Added `OverriddenPricing`, `AppliedOverrideID`, and `PricingOverrideIDs` fields to `ModelDetailsResponse`. `OverriddenPricing` carries post-override values only for fields the applied override actually changes; unaffected fields are omitted so the client knows exactly which prices to strike through.
- Added `ModelOverriddenPricing` struct holding the four displayed cost fields (`input_cost_per_token`, `output_cost_per_token`, `cache_creation_input_token_cost`, `cache_read_input_token_cost`) as nullable pointers.
- Added `ModelPricingOverrideSummary` struct and a top-level `PricingOverrides` map on `ListModelDetailsResponse`. Overrides are deduplicated at the response level rather than inlined per row — a single wildcard override matching every model is serialized once regardless of page size.
- Only global and provider-scoped overrides populate `OverriddenPricing`/`AppliedOverrideID`; virtual-key, user, and provider-key scoped overrides appear in `PricingOverrideIDs` for informational display only.
- A patch that sets a cost field to its existing catalog value is not treated as an override (no strike-through for identical numbers).
- Override resolution uses the model's catalog pricing mode (defaulting to `"chat"`) so an override scoped to a different mode never affects the displayed row.
- Added `buildOverriddenPricing`, `changedCost`, and `toPricingOverrideSummary` helpers to keep the handler loop readable.
- Added six focused tests covering: global override application without mutating base pricing, deduplication of the override index across multiple models, omission of new fields when no overrides exist, no-op patches that match the base value, overrides on models absent from the catalog, and virtual-key scoped overrides being informational only.

## How to test

```sh
go test ./transports/bifrost-http/handlers/... -run TestListModelDetails
```

Expected: all six new `TestListModelDetails_*` tests pass alongside the existing pricing tests.

To validate end-to-end, seed a global pricing override via the config store and call `GET /api/models/details?provider=openai`. Confirm:
- `overridden_pricing` appears only on models matched by the override and only for fields with a changed value.
- `pricing_overrides` at the response root contains one entry per unique override ID, not one per model row.
- Virtual-key scoped overrides appear in `pricing_override_ids` but do not set `overridden_pricing` or `applied_override_id`.

## Breaking changes

- [ ] Yes
- [x] No

New fields are additive and omitempty; existing consumers are unaffected.

## Security considerations

Override data returned is read-only metadata already accessible to authenticated callers of the model details endpoint. No new secrets or PII are introduced; virtual key IDs and user IDs present in override summaries are already stored in the config store and gated by existing auth middleware.

…imhq#6057)

## Summary

Pricing field metadata (`PRICING_FIELDS`, `REQUEST_TYPE_GROUPS`, related types and helpers) was previously defined inside `pricingOverrideSheet.tsx`. This meant any read-only consumer (e.g. a model-catalog detail sheet) that needed field labels would have to pull in the full form/mutation dependencies of that component. This PR extracts that metadata into a dedicated `pricingFields.ts` module and re-exports everything from `pricingOverrideSheet.tsx` to preserve backward compatibility for existing importers.

## Changes

- Extracted `PRICING_FIELDS`, `REQUEST_TYPE_GROUPS`, `REQUEST_TYPE_OPTIONS`, `getRequestTypeGroup`, `fieldLabelByKey`, `patchKeys`, `PricingFieldKey`, and `FieldErrors` from `pricingOverrideSheet.tsx` into a new `pricingFields.ts` file.
- `pricingOverrideSheet.tsx` now re-exports all of the above from `pricingFields.ts`, so no existing import paths break.
- `pricingFieldSelector.tsx` updated to import directly from `pricingFields.ts` instead of `pricingOverrideSheet.tsx`.
- The motivation is to allow lightweight, read-only consumers to import field labels without incurring the bundle cost of the override sheet's form and mutation logic.

## Summary

Surfaces custom pricing overrides in the model catalog UI. When a pricing override is applied to a model, the catalog table and detail sheet now show the original price struck through alongside the effective overridden price, and the detail sheet lists every override that matches the model with its scope, pattern, patch values, and any applicable caveats.

## Changes

- Added a new `OverriddenPrice` component that renders a base price normally when no override is active, or shows the original price struck through with the effective price beside it and a tooltip naming the override that produced it.
- Replaced all plain `formatTokenPriceCompact` / `formatTokenPriceFull` calls in the catalog table and attribute sheet with `OverriddenPrice`, so overridden fields are visually distinguished without affecting unoverridden rows.
- Added a "Pricing overrides" section to `AttributeSheet` that lists every override matching the model (including virtual-key, user, and provider-key scoped ones that don't change the displayed price), showing scope kind, match pattern, request type badges, patch field values, and a caveat explaining when context-dependent overrides apply.
- Added an "overrides" badge to the "Other" column in the catalog table showing how many overrides match each model.
- Extended `ModelDetails` with `overridden_pricing`, `applied_override_id`, and `pricing_override_ids` fields, and added `ModelOverriddenPricing` and `ModelPricingOverrideSummary` types to the store.
- Extended `ListModelDetailsResponse` with a `pricing_overrides` index (keyed by ID) that the attributes tab resolves override IDs against, skipping any that were deleted between fetches.
- Added `formatPatchValue` to render per-token/per-character patch values with the full token price formatter and all other fields as plain dollar amounts.

3. Hover the overridden price and confirm the tooltip names the override.
4. Click the edit icon for that model and confirm the "Pricing overrides" section appears in the sheet, listing the override with its scope badge, pattern, patch values, and (for virtual-key/user/provider-key scopes) the contextual caveat.
5. Confirm models with no overrides render identically to before.
6. Confirm the "Other" column shows an "overrides" badge for models with matching overrides.

## Summary

The active tab, search query, and provider filter in the Model Catalog are now stored in the URL query string instead of local React state. This means the view survives a page refresh and can be shared as a direct link that lands on the correct tab with filters already applied.

## Changes

- The selected tab (`overview` / `attributes`) is now managed via `useQueryState` with `nuqs`, using `history: "replace"` so tab clicks don't accumulate in browser history.
- The search input and provider filter in `AttributesTab` are now managed via `useQueryStates` with the same `history: "replace"` strategy, so typing doesn't flood browser history with one entry per keystroke.
- When the active provider filter no longer exists in the providers list, it is cleared by setting the URL param to `null` rather than calling a local state setter.
- A `parseAsSafeString` parser is used for the search and provider params to ensure safe URL deserialization.

2. Switch to the **Attributes** tab, type a search term, and select a provider filter.
3. Copy the URL and open it in a new tab — it should land on the Attributes tab with the same search and provider filter pre-applied.
4. Refresh the page — the tab, search, and provider filter should all be preserved.
5. Verify that typing in the search box does not create a new browser history entry per keystroke (back button should not step through each character).
6. Verify that switching tabs does not pile up history entries.

…oad (maximhq#6096)

## Summary

Eliminates the flash of the default Bifrost logo on branded enterprise deployments during client-side navigations and page reloads. Previously, the branding query was always a round trip, so every branded surface rendered the bundled Bifrost defaults until the response landed. This change persists the last known branding state to `localStorage` so the first paint can use the customer's assets immediately, without waiting for the network.

## Changes

- Introduced a `localStorage` cache (`bifrost-branding`) that stores the resolved `BrandingState` after each successful branding query response.
- Added `readCachedBranding` and `writeCachedBranding` helpers with guards against unparseable or malformed cache entries, and silent fallbacks when `localStorage` is unavailable (e.g. privacy mode).
- A module-level variable (`cachedBranding`) is populated once per page load and kept in sync, so repeated renders don't re-parse the cache entry.
- `useBranding` now falls back to the cached state (`data ?? readCachedBranding()`) while the query is in flight, rather than always falling back to the bundled defaults.
- Cache writes are funneled through a single `useEffect` that fires whenever the query data updates, including after save or reset mutations that invalidate the `Branding` tag.
- When branding is disabled or reset, the cache entry is removed so the defaults are correctly restored on the next load rather than showing a stale cached state.
- The pre-hydration server-side shell rewrite remains in place to cover the initial document load before any of this client-side logic runs.

**Trade-off:** A stale cached URL (e.g. after an admin re-uploads a logo) will 404 and show a broken image for a single frame before the in-flight response replaces it. This is considered acceptable against a guaranteed wrong-logo flash on every load.

1. Configure an enterprise deployment with custom branding (logo and icon uploaded).
2. Navigate to the dashboard and observe that the custom logo renders immediately on first paint without flashing the Bifrost default logo.
3. Reload the page and confirm the custom logo appears before the branding query completes.
4. Reset branding to defaults and reload — confirm the Bifrost defaults are shown and no stale cached logo appears.
5. Verify that re-uploading a logo updates the cache after the query resolves.

```sh
cd ui
pnpm i || npm i
pnpm test || npm test
pnpm build || npm run build
```

## Screenshots/Recordings

Before: Custom logo flashes the Bifrost default on every reload or client-side navigation until the branding API response lands.

After: Custom logo renders immediately on first paint using the `localStorage` cache.

Closes maximhq#3411.

Cloudflare Workers AI exposes an OpenAI-compatible surface for chat
completions and embeddings under the per-account base URL
  https://api.cloudflare.com/client/v4/accounts/<account_id>/ai/v1
so the new provider sits firmly on the OpenAI-compat path, delegating
chat / streaming / embeddings / list-models / responses to the shared
openai handlers in the same pattern as Cerebras, Groq, etc.

The one wrinkle is that there is no global default URL that omits the
account id. NewCloudflareProvider therefore returns an error when
network_config.base_url is empty rather than silently routing to a
broken endpoint.

What's wired up:

- core/providers/cloudflare/cloudflare.go — Provider implementation,
  modelled on Cerebras. Supports chat (streaming + non-streaming),
  responses (chat-fallback), embeddings, list models. Everything else
  returns NewUnsupportedOperationError.
- core/providers/cloudflare/cachedcontents.go — Mirrors the Cerebras
  unsupported-cached-content stubs so the Provider interface is
  satisfied.
- core/providers/cloudflare/cloudflare_test.go — Comprehensive
  llmtests config gated on CLOUDFLARE_API_KEY + CLOUDFLARE_ACCOUNT_ID
  (skips when unset, mirroring the Cerebras test pattern), plus a unit
  test that locks in the "base_url is required" contract without
  needing network access.
- core/schemas/bifrost.go — Cloudflare ModelProvider constant added to
  StandardProviders.
- core/bifrost.go — createBaseProvider wires schemas.Cloudflare to
  cloudflare.NewCloudflareProvider.
- docs/providers/supported-providers/cloudflare.mdx + docs/docs.json
  navigation entry.
- docs/openapi/openapi.json + transports/config.schema.json — provider
  enums updated in all required spots.
- ui/lib/constants/{config.ts,icons.tsx,logs.ts} — placeholder, key
  requirement, label, embedding-supported list, and a Cloudflare brand
  cloud icon.
- .github/workflows/{pr-tests.yml,release-pipeline.yml} +
  scripts/test-docker-image.sh — CLOUDFLARE_API_KEY and
  CLOUDFLARE_ACCOUNT_ID added everywhere CEREBRAS_API_KEY is wired.
  Maintainers will need to set the matching repository secrets;
  without them the integration test skips cleanly.

Verification:

- go build ./... passes.
- go test ./providers/cloudflare/... passes (TestCloudflare skips
  without keys; TestCloudflareRequiresBaseURL passes).
- go test ./providers/... — all packages green except the
  pre-existing TestBifrostToGeminiToolConversion failure on main,
  which is unrelated to this change.
- npm run lint (UI) — 0 errors, 387 pre-existing warnings unchanged.

…verride, harden-runner allowlist

Three review fixes from Greptile and CodeRabbit on maximhq#3604:

1. .github/workflows/scripts/test-docker-image.sh — the heredoc that
   writes config.json is single-quoted (correctly, since `env.XXX`
   strings are resolved by Bifrost itself), so $CLOUDFLARE_ACCOUNT_ID
   in the cloudflare base_url was being written literally and the
   integration test would hit an invalid URL when the secret is set.
   Substitute it after the heredoc with sed using a non-/ delimiter
   so the URL slashes don't need escaping.

2. core/providers/cloudflare/cloudflare.go — ChatCompletionStream now
   builds its URL with providerUtils.GetPathFromContext, matching
   ChatCompletion / Embedding / ListModels and respecting any
   context-set path override.

3. .github/workflows/release-pipeline.yml — added api.cloudflare.com:443
   to all 4 step-security/harden-runner allowlists that already
   include api.cerebras.ai:443, so the Cloudflare integration tests
   can reach the upstream API under the egress-policy: block jobs.
Greptile flagged that the integration test would error with
"unsupported provider: cloudflare" rather than passing once both
CLOUDFLARE_API_KEY and CLOUDFLARE_ACCOUNT_ID are set in CI, because
ComprehensiveTestAccount's three callbacks didn't know about the
new provider.

Adds schemas.Cloudflare to:

- GetConfiguredProviders — pre-registers the provider on Bifrost
  startup, alphabetically next to Cerebras.
- GetKeysForProvider — returns env.CLOUDFLARE_API_KEY with the same
  shape as the Cerebras key entry.
- GetConfigForProvider — composes BaseURL from CLOUDFLARE_ACCOUNT_ID
  via fmt.Sprintf, since Workers AI's URL embeds the account id and
  there is no usable default.
…ovider

Two more review fixes from Greptile and CodeRabbit on maximhq#3604:

1. Greptile (P1, confidence 3/5): every Cloudflare endpoint URL was
   constructed with a double `/v1/` segment because the documented
   base URL ended in `/ai/v1` and the provider also appended
   `/v1/...`, so live calls went to `…/ai/v1/v1/chat/completions` and
   would 404. The cause is that I diverged from the Cerebras/Groq
   convention — those providers have the base URL stop at the host
   (`https://api.cerebras.ai`) and append `/v1/...` per request. The
   fix is to stop the documented Cloudflare base URL at `/ai`,
   matching the cohort. Provider code is unchanged; only the
   documented / fixture URLs move.

   Updated:
     - core/internal/llmtests/account.go (test fixture)
     - .github/workflows/scripts/test-docker-image.sh (docker config)
     - core/providers/cloudflare/cloudflare.go (package doc + the
       constructor's error message that suggests the URL)
     - core/providers/cloudflare/cloudflare_test.go (URL the unit
       test asserts the constructor accepts)
     - docs/providers/supported-providers/cloudflare.mdx (user
       guidance + the caveat block that referenced the URL)

2. CodeRabbit (Major, outside-diff): SupportedBaseProviders omitted
   Cloudflare while StandardProviders and the
   custom_provider_config schema enums included it, so a
   schema-valid custom-provider config backed by Cloudflare would be
   rejected by the runtime allowlist. Added schemas.Cloudflare to
   SupportedBaseProviders alongside the other OpenAI-compat-friendly
   bases.

Skipped two CodeRabbit suggestions intentionally:

- Deep-copy NetworkConfig.ExtraHeaders to avoid a shared-map race.
  No provider in core/providers/* deep-copies it today (cerebras,
  groq, mistral, cohere, …); changing only cloudflare would make it
  the inconsistent one. If the race is real, it should be addressed
  repo-wide in a separate PR.
- Replace `schemas.Cloudflare` with `provider.GetProviderKey()` in
  the streaming call. Same reason — every other OpenAI-compat
  provider hardcodes its own ModelProvider in HandleOpenAIChat
  CompletionStreaming (cerebras line 168, etc.). Matching the cohort
  for now.
…rsisting

CodeRabbit (Minor): the constructor checked
strings.TrimSpace(config.NetworkConfig.BaseURL) for emptiness but
then ran strings.TrimRight on the un-stripped original, so
"  https://api.cloudflare.com/.../ai/  " would pass the empty check
and end up stored with the leading space intact, which would break
request URL construction.

Fix is one extra local: assign baseURL := strings.TrimSpace(...) up
front, use it for both the empty check and the TrimRight before
persisting. Adds an explicit unit-test case that constructs a
whitespace-padded URL and asserts the provider builds cleanly, so
this regression has a guard.

59609-59620: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Align the OpenAPI budget schemas with runtime validation.

The API accepts quarter_start_month: 0 as January, but the OpenAPI schemas require a minimum of 1. They also omit the if/then constraint that requires reset_duration: "1Q" when reset_config is present. Update both management schema sources, then regenerate docs/openapi/openapi.json.
