📝 WalkthroughSummary by CodeRabbit
WalkthroughDeepSeek V4 Flash and Pro Anthropic-compatible requests preserve reasoning and model fidelity. Requests reject unsupported content before provider egress. Unary and streaming responses validate usage metadata and return fallback-enabled fidelity errors when validation fails. ChangesDeepSeek V4 Anthropic compatibility
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The PR changes DeepSeek V4 request and response handling, but a changed line still uses a deprecated field that can fail the repository’s lint gate. Merge should wait for that lint issue to be corrected or explicitly accepted; no separate runtime, security, or availability risk is evidenced. Sequence Diagram(s)sequenceDiagram

Both decoders drop the underlying
err. The emitteddeepseek_usage_fidelitymessage then states only that decoding failed. An operator cannot tell whether the payload was truncated, was not JSON, or had a type mismatch.
fmt.Errorfwith no verb also triggers a lint warning in some configurations, because the call has no formatting directive.♻️ Proposed fix to preserve the decode cause

The comment at lines 586-588 in
core/providers/anthropic/chat.gostates that legacythinkingis never synthesized, "including when a neutral max_tokens value coexists". Thechatsub-test sets bothEffortandMaxTokens, so it does not isolate the max-tokens-only input. A request withMaxTokensset andEffortnil takes the same branch and must produce neitherthinkingnoroutput_config.effort.Add that case so the branch claim is covered directly.

@coderabbitai The refreshed docstring metric is now 64.58% (31 of 48), but every newly introduced top-level function has an adjacent identifier-prefixed Go doc comment. The arithmetic indicates that comments in package anthropic were counted while comments in package deepseek_test were not. Please independently audit the current base-to-head diff and list the exact changed function declarations that lack a recognized docstring. Do not trigger another review. |

The current base-to-head audit documents every changed top-level Go function, and CodeRabbit independently confirmed that its missing-declaration list is empty. The residual 68.75% is a false negative for documented functions in the external deepseek_test package. |

… to `incomplete` status with `content_filter` incomplete details (maximhq#6103) ## Summary When Bedrock returns a `content_filtered` or `guardrail_intervened` stop reason, the response was previously passed through without setting `Status` or `IncompleteDetails`, making it indistinguishable from a genuine empty completion. This PR ensures that content-filtered and guardrail-blocked turns are surfaced as `status: "incomplete"` with `incomplete_details.reason: "content_filter"` in both the non-streaming and streaming Responses API paths, as well as in the Chat-to-Responses conversion layer. ## Changes - Added a `bedrockStopReasonContentFilter` / `bedrockStopReasonGuardrailIntervened` constant pair in `utils.go` to avoid magic strings across the Bedrock provider. - In `ToBifrostResponsesResponse`, extended the stop-reason switch to handle `content_filter` and `guardrail_intervened` by setting `Status = "incomplete"` and `IncompleteDetails.Reason = "content_filter"`, matching the same pattern already used for `max_tokens` truncation. - In `FinalizeBedrockStream`, added the same case to the streaming finalization switch so the terminal SSE event is emitted as `response.incomplete` rather than `response.completed`. - In `responsesStatusFromChatFinishReason` (mux layer), added `content_filter` and `guardrail_intervened` as mapped reasons that resolve to `incomplete` + `content_filter`, so the fix applies uniformly when Chat responses are converted to Responses format. - Updated existing tests that previously treated `content_filter` as an unmapped/pass-through reason to use a genuinely unmapped reason (`some_unknown_reason` / `some_unmapped_reason`), and added new dedicated tests covering both the non-streaming and streaming content-filter paths. ## Type of change - [x] Bug fix ## Affected areas - [x] Core (Go) - [x] Providers/Integrations ## How to test ```sh go test ./core/providers/bedrock/... ./core/schemas/... ``` The new tests assert: - `ToBifrostResponsesResponse` with `content_filtered` or `guardrail_intervened` stop reasons produces `Status = "incomplete"` and `IncompleteDetails.Reason = "content_filter"`. - `FinalizeBedrockStream` with those stop reasons emits a `response.incomplete` terminal event with the same fields. - `ToBifrostResponsesResponse` (mux) with `content_filter` or `guardrail_intervened` finish reasons maps to `incomplete` + `content_filter`. - Genuinely unmapped stop reasons still leave `Status` unset. ## Breaking changes - [ ] Yes - [x] No ## Security considerations This change ensures content-filtered responses are never silently presented as successful empty completions, which reduces the risk of downstream agents treating a blocked turn as a valid empty output. ## Checklist - [ ] I read `docs/contributing/README.md` and followed the guidelines - [x] I added/updated tests where appropriate - [ ] I updated documentation where needed - [x] I verified builds succeed (Go and UI) - [ ] I verified the CI pipeline passes locally if applicable
## Summary Introduces a `BifrostContextKeySkipProviderCheck` context flag for requests that are evaluated by governance but never routed (e.g., `/inspect`). For these requests, the provider is whatever upstream the caller was already talking to rather than an operator-selected provider, so the virtual key's provider allowlist is meaningless. Without this flag, such requests would be incorrectly blocked by the VK provider gate, and then if that were bypassed, would fail again on a model allowlist that only exists inside a provider config the VK doesn't have. Also bumps `github.com/bytedance/sonic` from v1.15.1 to v1.15.2 across all modules. ## Changes - Added `BifrostContextKeySkipProviderCheck` context key (`bifrost-skip-provider-check`) to `core/schemas/bifrost.go` and registered it as a reserved key in `core/schemas/context.go`. - `EvaluateVirtualKeyRequest` in `plugins/governance/resolver.go` now accepts a `skipProviderCheck bool` parameter. When set, the provider allowlist gate is skipped. Additionally, if the VK has no provider config for the requested provider (meaning it also has no model allowlist for it), the model gate is skipped as well. A provider the VK does configure retains its model allowlist regardless of the flag. - `EvaluateGovernanceRequest` in `plugins/governance/main.go` reads the new context key and passes it through to `EvaluateVirtualKeyRequest`. - `github.com/bytedance/sonic` bumped to v1.15.2 across all modules. - `google.golang.org/x/crypto`, `x/net`, `x/sync`, `x/sys`, and `x/text` bumped to latest patch versions in test seed modules. - Node engine constraint removed from `ui/package.json`. ## Type of change - [ ] Bug fix - [x] Feature - [ ] Refactor - [ ] Documentation - [ ] Chore/CI ## Affected areas - [x] Core (Go) - [ ] Transports (HTTP) - [ ] Providers/Integrations - [x] Plugins - [ ] UI (React) - [ ] Docs ## How to test Two new tests cover the behavior directly: - `TestBudgetResolver_EvaluateRequest_SkipProviderCheckAllowsUnconfiguredProvider` — verifies that a VK with no config for the requested provider allows the request when the flag is set, and does not fall through to a model block. - `TestBudgetResolver_EvaluateRequest_SkipProviderCheckKeepsModelAllowlist` — verifies that a provider the VK does configure keeps its model allowlist enforced even when the flag is set. ```sh cd plugins/governance go test ./... -run TestBudgetResolver_EvaluateRequest_SkipProviderCheck ``` ## Breaking changes - [ ] Yes - [x] No The `EvaluateVirtualKeyRequest` signature gains a new `skipProviderCheck bool` parameter. All internal call sites have been updated. External callers implementing the interface directly will need to add the parameter. ## Security considerations The flag is intended exclusively for transport-set, read-only inspection paths where the provider is not an operator choice. It bypasses the VK provider and (for unconfigured providers) model allowlists only for those requests. VK existence, active status, expiry, rate limits, and budgets are unaffected. The flag is registered as a reserved context key so it cannot be set by arbitrary plugin or caller code without going through the transport layer. ## Checklist - [x] I read `docs/contributing/README.md` and followed the guidelines - [x] I added/updated tests where appropriate - [ ] I updated documentation where needed - [x] I verified builds succeed (Go and UI) - [x] I verified the CI pipeline passes locally if applicable
…aximhq#6075) * feat(runware): support async 3D generation via the /videos endpoint Runware exposes 3D model generation as a `3dInference` task on the same async submit-then-poll endpoint as video. The video request builder hardcoded `taskType: videoInference` and always injected 16:9 1080p width/height, so 3D tasks could not be driven through /videos. - Read an optional `taskType` from extra_params (default videoInference) so /videos can drive any Runware async task type. - Apply the width/height video defaults only for the videoInference task type; 3D uses `resolution` and rejects width/height. - Surface `outputs.files[].url` (the 3D artifact list) into the response as VideoOutput URLs, deriving content-type from the file extension (.glb -> model/gltf-binary, etc). Cost is left untracked ($0) for now; a provider-reported cost hook will follow. * feat(runware): add passthrough route for non-modeled task types Runware exposes a single task-based endpoint, so many capabilities (3D, upscaling, background removal, ...) have no first-class Bifrost surface. Implement the Passthrough method to forward raw task arrays to Runware's endpoint and return the untouched response, while Bifrost still injects the key, strips client auth, and logs the call. - Implement RunwareProvider.Passthrough + buildPassthroughURL. Runware's base URL already includes /v1, so a leading /v1 in the passthrough path is stripped to avoid duplication. - Add NewRunwarePassthroughRouter (/runware_passthrough) and register it in the integrations handler. - Add a router registration test. PassthroughStream stays unsupported (Runware polls rather than streams). Cost is left untracked ($0) for passthrough; a provider-reported cost hook reading data[].cost will follow. Verified live against a local gateway: imageInference, upscale (prunaai:p-image@upscale and runware:501@1), imageBackgroundRemoval, and 3dInference all forward correctly with key injection. * feat(runware): surface provider-reported cost across image, video/3D, and passthrough Runware returns an exact per-task `cost` (when the request sets includeCost). Surface it as the provider-reported cost so pricing uses it verbatim instead of a datasheet estimate — important for task types like 3D that have no datasheet rate. - Image generation: sum data[].cost into ImageUsage.Cost. - Video / 3D: add VideoUsage{Cost} to BifrostVideoGenerationResponse, populate it from the task result, and add a cost-engine branch that routes it through the provider-cost short-circuit. - Passthrough: add Cost to BifrostPassthroughUsage, map it in passthroughUsageToCostInput, and add ExtractRunwarePassthroughUsage reading data[].cost; wired into the Passthrough method. All paths are nil-guarded: when no cost is reported, behavior is unchanged (datasheet pricing, or $0 for raw passthrough). No other provider is affected — the new cost-engine branches only fire on the Runware-only fields. Verified live: image gen (usage.cost 0.0006) and text-to-3D via /videos (usage.cost 0.2, .glb returned) surface the reported cost end-to-end. * docs(runware): document 3D generation, passthrough route, and cost tracking Reflect the new Runware capabilities on the provider page: - 3D model generation via /videos (taskType=3dInference), incl. the image-to-3D limitation that routes users to passthrough. - The /runware_passthrough raw task-array route and async submit/poll. - Cost tracking: Runware's per-task cost (includeCost) is surfaced as the provider-reported cost and overrides datasheet pricing. * fix(runware): honor send_back_raw config in passthrough response The passthrough method ignored the provider's sendBackRawRequest / sendBackRawResponse settings. Expose the raw upstream request/response to callers via ExtraFields when those flags are enabled, matching the contract the provider's typed methods already follow (internal store_raw logging remains handled separately). Addresses CodeRabbit review. * fix(pricing): avoid mutating caller usage when attaching passthrough cost passthroughUsageToCostInput aliased the caller's su.LLMUsage into input.usage, then wrote Cost onto it in place — mutating the shared response usage on what is a pure-read cost path. Copy the usage value before assigning Cost. Adds a regression test asserting the source usage is unchanged. Addresses CodeRabbit review.

…and add customer/BU dimensions to seed manifest (maximhq#6137) ## Summary Callers with narrowed virtual key visibility (enterprise DAC-scoped principals) could bypass access controls by appending `?from_memory=true` to the list and detail virtual key endpoints. The in-memory governance snapshot carries no notion of the calling principal, so it returned every cached key regardless of entitlement. This PR gates the snapshot path behind a `virtualKeyViewScoper` check and falls through to the scoped config store for narrowed callers. A separate but related bug caused the DAC fixture manifest to under-predict visibility for shapes carrying only a customer or business unit dimension — the `computeVisibleTo` function was missing those two branches entirely. Because the negative shapes had hardcoded `VisibleTo` lists that happened to be correct, only the computed (tiggings) side disagreed with the server, surfacing as the team reader appearing to return 30 extra rows. ## Changes - **`governance.go`**: Introduced `virtualKeyViewScoper` interface and `mayServeVirtualKeysFromMemory` helper. Both `getVirtualKeys` and `getVirtualKey` now skip the snapshot and delegate to the scoped config store when the caller's view is narrowed. - **`governance_test.go`**: Added `newVKHandlerForFromMemory` factory with a `viewScoped` flag and a key present only in the snapshot, making snapshot vs. store reads distinguishable. Added tests covering the bypass fix for both the list and detail endpoints, and for the scoped caller preserving the `user_id` filter that the in-memory branch rejects. - **`seed.go`**: Added `customer_id` and `business_unit_id` branches to `computeVisibleTo`, mirroring the enterprise log scope predicate. Introduced `dacFixtureIDs` struct to replace positional string arguments, preventing silent dimension-pair swaps. Removed hardcoded `VisibleTo` lists from the three negative shapes and derived them through `computeVisibleTo` instead. - **`visibility_manifest_test.go`**: New test file pinning the manifest to the scope predicate — specifically that `only-business-unit` is visible to `team_reader_tiggings` but not `own_reader_tiggings` or `team_reader_outside`, that `legacy-unowned` stays admin-only, and that the 15-shape matrix is fully visible to the tiggings team reader. ## Type of change - [x] Bug fix - [ ] Feature - [ ] Refactor - [ ] Documentation - [ ] Chore/CI ## Affected areas - [ ] Core (Go) - [x] Transports (HTTP) - [ ] Providers/Integrations - [ ] Plugins - [ ] UI (React) - [ ] Docs ## How to test ```sh go test ./transports/bifrost-http/handlers/... ./tests/cmd/seed/... ``` The new governance tests assert that a scoped caller receives a 404 (detail) or an empty store-backed response (list) rather than the snapshot contents, and that an unscoped caller still reaches the snapshot. The seed tests assert the `only-business-unit` shape carries `team_reader_tiggings` in its `VisibleTo` list and that all 15 matrix shapes are visible to the tiggings team reader. ## Breaking changes - [x] No ## Security considerations The `from_memory=true` flag on the virtual key endpoints was exploitable by any caller whose config store is DAC-scoped: appending the flag returned the full unscoped in-memory snapshot, leaking keys belonging to other customers, teams, or users. The fix is fail-closed — stores that do not implement `virtualKeyViewScoper` (OSS) are unaffected and continue to use the snapshot as before. ## Checklist - [x] I added/updated tests where appropriate - [x] I verified builds succeed (Go and UI)

…creen (maximhq#6126) ## Summary Adds graceful version-skew handling so that when Bifrost is being rolled out, users see a clear "upgrading" UI instead of a broken page. Stale asset errors (failed dynamic imports, chunk load failures) are detected, classified, and surfaced through two purpose-built screens: a non-blocking banner for soft failures and a full-page upgrade screen for hard failures. An auto-reload mechanism polls `/api/version` for stability and reloads the page automatically, with a session-storage guard to prevent reload loops. ## Changes - **`versionSkew.ts`** — New utility module that classifies skew errors by matching known browser/bundler error patterns (`ChunkLoadError`, failed dynamic imports, etc.), maintains a reactive `SkewMode` store (`none | soft | hard`), installs global listeners for `vite:preloadError`, `unhandledrejection`, and asset element errors, and manages a session-storage reload budget (`MAX_AUTO_RELOADS = 2` within a 60-second window) to prevent infinite reload loops. - **`__updating.tsx`** — New `UpdatingBanner` (non-blocking overlay for soft skew) and `UpdatingScreen` (full-page replacement for hard skew) components. `UpdatingScreen` polls `/api/version` every 3 seconds, requires 3 consecutive matching responses before triggering an auto-reload, and times out after 90 seconds with a manual reload fallback. - **`__error.tsx`** — `ErrorComponent` now receives the error prop and redirects to `UpdatingScreen` when a skew error is detected, escalating to hard mode via `reportSkew("hard")`. - **`clientLayout.tsx`** — Adds a `ConfigUnreachable` component shown when the core config fetch fails, with a retry button wired to RTK Query's `refetch`. `FullPage` now receives `hasError`, `isRetrying`, and `onRetry` props to drive this state. - **`main.tsx`** — Introduces a `Root` component that subscribes to the skew store via `useSyncExternalStore`, renders `UpdatingScreen` on hard skew, overlays `UpdatingBanner` on soft skew, and clears the auto-reload guard after 30 seconds of healthy uptime. Sets `window.__bifrostBooted` to coordinate with the inline boot script. - **`index.html`** — Adds an inline script that renders a minimal native-HTML upgrading screen if assets fail to load before React boots, using the same session-storage reload guard logic to cap retries. - **`globals.css`** — Adds the `update-progress` keyframe animation used by the progress bar in `UpdatingScreen`, and fixes a nested media query indentation issue. - **`versionSkew.test.ts`** — Full test coverage for `isSkewError`, the skew store (subscribe/notify/escalation/downgrade prevention), and the auto-reload guard (budget exhaustion, window expiry, `clearAutoReloadGuard`, and `sessionStorage` unavailability). ## Type of change - [ ] Bug fix - [x] Feature - [ ] Refactor - [ ] Documentation - [ ] Chore/CI ## Affected areas - [ ] Core (Go) - [ ] Transports (HTTP) - [ ] Providers/Integrations - [ ] Plugins - [x] UI (React) - [ ] Docs ## How to test ```sh cd ui pnpm i pnpm test pnpm build ``` To manually verify: 1. Build the UI and serve it, then invalidate a JS asset URL (e.g., rename a chunk file) to trigger a `ChunkLoadError`. The upgrading banner or screen should appear. 2. Reload the page more than twice within 60 seconds while skew is active — the auto-reload should stop and display the manual reload fallback. 3. Simulate a failed `/api/core-config` response; the `ConfigUnreachable` card should appear with a working "Try again" button. ## Screenshots/Recordings - **Soft skew:** A fixed bottom banner reading "Bifrost is upgrading" with a manual reload button appears without disrupting the current view. - **Hard skew / boot failure:** A full-page card with an animated progress bar, status text, and "Reload now" button replaces the broken route. - **Config unreachable:** A card with a `WifiOff` icon and retry button is shown in the main content area. **Soft skew**  **Hard skew**  ## Breaking changes - [ ] Yes - [x] No ## Related issues ## Security considerations The auto-reload guard uses `sessionStorage`, which is scoped to the tab and origin. No auth tokens or PII are stored. The inline boot script in `index.html` is self-contained and does not make authenticated requests. ## Checklist - [x] I read `docs/contributing/README.md` and followed the guidelines - [x] I added/updated tests where appropriate - [ ] I updated documentation where needed - [x] I verified builds succeed (Go and UI) - [ ] I verified the CI pipeline passes locally if applicable

Summary
DeepSeek's official Anthropic-compatible API exposes two reviewed V4 model identities:
deepseek-v4-flashdeepseek-v4-proBoth use
output_config.effortfor active reasoning andthinking.type=disabledfor an explicitnone. DeepSeek also documents that unsupported model names may be mapped to V4 Flash, so Bifrost must verify the served model and complete usage metadata before accepting a response.A bounded Stage R validation of the exact Pro identity on 2026-08-14 also exposed a separate contract gap: an image-shaped request returned HTTP 200 from DeepSeek even though the Anthropic-compatible documentation marks image and document blocks unsupported. Because the provider accepted the request, an upstream-error-driven fallback never ran. This update therefore adds a local, exact-gated content boundary before conversion or provider egress.
After this guard merged downstream as the exact carried patch, a fresh separately authorized Stage R rerun against LaneTally merge
13335f904b2c3a4d69ae57ae52e69431159f53b7returnedGREEN — DEEPSEEK-V4-PRO-GREEN. Six real Pro requests re-proved exact identity, xhigh acceptance, conserving cache accounting, parallel tools, and tool-result continuation. The unsupported-content client facet made no DeepSeek request: the local guard intercepted it and terminal mock Qwen received the original request intact. Production was not contacted.

Affected areas
How to test
Red-before-green was captured at the shared builder boundary: before the guard, all four exact DeepSeek V4 Chat/Responses unary/streaming cases serialized the unsupported payload; after the guard, the same test returns the typed local 415.
Validated on Go 1.26.5:
All commands pass at
90dc72c50. Structural harness validation retains exactly four new requests. No paid full provider-harness sweep was run. The separately authorized downstream Stage R rerun described above was bounded to six real Pro requests; its unsupported-content facet was intercepted locally and made zero DeepSeek requests.Screenshots/Recordings
Not applicable.
Breaking changes
Only the exact official DeepSeek V4 Flash and V4 Pro Anthropic paths change. Invalid response metadata now fails safely, and unsupported image/document content now spills locally to an explicitly configured fallback instead of relying on provider rejection.

No existing issue found.
Security considerations
The response-fidelity decoder is deliberately metadata-only. The request guard reads content kinds only and never copies payload values into its error. Validation errors are sanitized; raw provider responses, request content, authentication material, and PII are not attached.
