…filter inaccessible sidebar items (#3295) This PR improves RBAC granularity in the sidebar by introducing dedicated resource types for `APIKeys`, `Inference`, and `Metrics`, and fixes sidebar visibility logic so that items and groups are hidden when the user lacks access rather than relying on broader, less specific permissions. - Added three new `RbacResource` enum values: `APIKeys`, `Inference`, and `Metrics` to the fallback RBAC context. - The API Keys sidebar item now gates access via the new `hasAPIKeyAccess` (`RbacResource.APIKeys`) check instead of the generic `hasSettingsAccess`. - The MCP Logs sidebar item now correctly gates access via `hasMCPGatewayAccess` instead of the unrelated `hasLogsAccess`. - Introduced an `accessibleItems` memoized computation that filters out sidebar items and entire groups whose sub-items are all inaccessible, ensuring users never see empty navigation sections. Previously, access filtering only happened during search. - Removed unused imports (`PanelLeft`, `PanelRight`, `cn`). - [ ] Bug fix - [x] Feature - [x] Refactor - [ ] Documentation - [ ] Chore/CI - [ ] Core (Go) - [ ] Transports (HTTP) - [ ] Providers/Integrations - [ ] Plugins - [x] UI (React) - [ ] Docs 1.

…elete access (#3314) The delete button in log tables was always rendered (just disabled) for users without delete access. This PR hides the actions column entirely when the user lacks delete permissions, and fixes the RBAC resource check for MCP logs to use the correct `MCPGateway` resource instead of `Logs`. - The actions column in both the workspace logs and MCP logs tables is now conditionally included in the column definitions only when `hasDeleteAccess` is `true`, rather than always rendering a disabled button. - The delete button styling was updated to use more visible destructive colors (`text-destructive/60 border-destructive/60`) instead of the previous muted secondary foreground styles. - The RBAC resource used to gate delete access on the MCP logs page was corrected from `RbacResource.Logs` to `RbacResource.MCPGateway`. - [x] Bug fix - [ ] Feature - [ ] Refactor - [ ] Documentation - [ ] Chore/CI - [ ] Core (Go) - [ ] Transports (HTTP) - [ ] Providers/Integrations - [ ] Plugins - [x] UI (React) - [ ] Docs 1.

…SQL helper to prevent malformed JSON from aborting list queries (#3407) ## Summary The `/api/logs` list query was aborting entirely when a single row contained malformed JSON in `input_history` or `responses_input_history`. The previous inline guard only checked the first character before casting to `jsonb`, so rows that appeared array-shaped but contained malformed JSON (unterminated structures, trailing commas, unpaired UTF-16 surrogates, `\u0000` escapes, etc.) would trigger a `22P02`/`22P05` error and kill the entire response. This PR fixes that by introducing a PL/pgSQL helper function (`bifrost_safe_jsonb`) that wraps the cast in an `EXCEPTION` block and falls back to returning the raw text on any parse failure. ## Changes - Added a new migration `migrationAddSafeJsonbFunction` that installs the `bifrost_safe_jsonb(text)` PL/pgSQL function on Postgres. The function validates the input, attempts the `jsonb` cast inside an `EXCEPTION` block, and returns the last array element on success or the raw text on any failure. - Replaced the multi-condition inline `CASE` guards in `listSelectColumns` for Postgres with calls to `bifrost_safe_jsonb`, simplifying the SQL and correctly handling all malformed-JSON edge cases that the previous character-check approach missed. - For SQLite, added `json_valid()`, `json_type()`, and `json_array_length()` guards to the `CASE` expressions to prevent extraction attempts on invalid or empty arrays. - Added `safe_jsonb_test.go` covering both the SQLite and Postgres dialect branches of `listSelectColumns`, as well as direct invocation of `bifrost_safe_jsonb` across all relevant edge cases (malformed structures, surrogate pairs, `\u0000` escapes, non-array values, SQL `NULL`). ## Type of change - [x] Bug fix - [ ] Feature - [ ] Refactor - [ ] Documentation - [ ] Chore/CI ## Affected areas - [x] Core (Go) - [ ] Transports (HTTP) - [ ] Providers/Integrations - [ ] Plugins - [ ] UI (React) - [ ] Docs ## How to test ```sh cd framework && docker compose up -d postgres go test ./framework/logstore/ -run 'MalformedInputHistory|BifrostSafeJsonb' -count=1 -v ``` Insert a row into the logs table with a malformed JSON value in `input_history` (e.g., `[{"key": "val"` — unterminated) and verify that a call to the list endpoint returns successfully without a 500 error, with the malformed row's `input_history` returned as raw text rather than aborting the query. ## Test Coverage ### `TestSearchLogs_MalformedInputHistory_{SQLite,Postgres}` — end-to-end list query | # | Case | Column | Payload shape | Pre-fix behavior | Path exercised | | --- | --- | --- | --- | --- | --- | | 1 | `unterminated_object_in_array` | `input_history` | `[{"role":"user","content":"hi"` | 22P02 aborts query | EXCEPTION fallback | | 2 | `garbage_after_bracket` | `input_history` | `[abc, not json]` | 22P02 aborts query | EXCEPTION fallback | | 3 | `trailing_comma` | `input_history` | `[{"role":"user","content":"hi"},]` | 22P02 aborts query | EXCEPTION fallback | | 4 | `unclosed_array_only` | `input_history` | `[` | 22P02 aborts query | EXCEPTION fallback | | 5 | `open_bracket_then_brace_unclosed` | `input_history` | `[{` | 22P02 aborts query | EXCEPTION fallback | | 6 | `nan_value_not_valid_json` | `input_history` | `[NaN]` | 22P02 aborts query | EXCEPTION fallback | | 7 | `infinity_value_not_valid_json` | `input_history` | `[Infinity]` | 22P02 aborts query | EXCEPTION fallback | | 8 | `unpaired_high_surrogate` | `input_history` | `[{"...":"bad \uD800 surrogate"}]` | 22P05 aborts query | EXCEPTION fallback | | 9 | `unpaired_low_surrogate` | `input_history` | `[{"...":"bad \uDC00 low"}]` | 22P05 aborts query | EXCEPTION fallback | | 10 | `bad_surrogate_pair_high_then_ascii` | `input_history` | `[{"c":"\uD800A"}]` | 22P05 aborts query | EXCEPTION fallback | | 11 | `u0000_escape_inside_string` | `input_history` | `[{"...":"null byte � here"}]` | 22P05 aborts query | EXCEPTION fallback | | 12 | `literal_backslash_u0000_valid_jsonb` | `input_history` | `[{"...":"... \\u0000 literal"}]` | OK (degraded to raw by old guard) | Fast path, last-element extraction | | 13 | `single_element_array` | `input_history` | `[{"role":"user","content":"only one"}]` | OK | Fast path | | 14 | `array_of_primitives` | `input_history` | `[1,2,3]` | OK | Fast path | | 15 | `array_with_null_last_element` | `input_history` | `[{...}, null]` | OK | Fast path | | 16 | `deeply_nested_valid` | `input_history` | `[{"role":"user","content":{"nested":{"deep":{"value":42}}}}]` | OK | Fast path | | 17 | `unicode_emoji_content` | `input_history` | `[{"...":"hello 🎉 world ✨"}]` | OK | Fast path | | 18 | `large_valid_array` | `input_history` | 1001-element array | OK | Fast path at scale | | 19 | `leading_whitespace_then_array` | `input_history` | ` [\t{...}]` | OK | `btrim` + fast path | | 20 | `top_level_object_not_array` | `input_history` | `{"not":"an array"}` | OK | Non-array fall-through | | 21 | `null_literal` | `input_history` | `null` | OK | Non-array fall-through | | 22 | `whitespace_only` | `input_history` | `" \t "` | OK | Empty-after-btrim fall-through | | 23 | `realtime_turn_malformed_passthrough` | `input_history` (object_type=`realtime.turn`) | `[{"role":"user"` | OK (outer CASE bypassed safe fn) | Realtime-turn bypass branch | | 24 | `malformed_responses_input_history` | `responses_input_history` | `[{"role":"user"` | 22P02 aborts query | Mirror column, EXCEPTION fallback | | 25 | `valid_responses_input_history` | `responses_input_history` | `[{...},{...}]` | OK | Mirror column, fast path | ## Breaking changes - [ ] Yes - [x] No ## Related issues [https://github.com/maximhq/bifrost/issues/3255](https://github.com/maximhq/bifrost/issues/3255#issuecomment-4427506449) ## Security considerations None.

…3412) ## Summary Adds support for server-configured required request headers in the prompt playground. When the server specifies `required_headers` in its client config, users can now provide values for those headers directly in the settings panel, and they are forwarded with every chat completion request. ## Changes - Added `customHeaders` state and `requiredHeaders` derived from the core config's `client_config.required_headers` to the `PromptContext`, keeping header keys in sync with the server config while preserving user-entered values. - Exposed a "Required Headers" section in the settings panel that renders an input field for each required header name when any are configured. - Extended `ExecutionConfig` in the executor to accept `customHeaders`, which are merged into the fetch request headers (skipping any entries with empty names or values). - Passed `customHeaders` through both `handleSubmit` and `handleSubmitToolResult` execution paths and included it in their respective `useCallback` dependency arrays. ## 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 1.

… bar click suppression (#3431) Adds a log volume histogram chart to the MCP Logs page, matching the existing chart behavior on the main Logs page. Also fixes a bug where clicking a bar immediately after a drag-select would overwrite the dragged time range with a single-bucket zoom. - Added `useGetMCPHistogramQuery` to the MCP Logs page to fetch histogram data with optional polling, and rendered the `LogsVolumeChart` component in the MCP Logs view. - Added `handleTimeRangeChange`, `handleResetZoom`, and `isZoomed` logic to the MCP Logs page, mirroring the behavior already present on the main Logs page. - Fixed `isZoomed` on the main Logs page to return `false` when a named `period` (e.g. `"1h"`) is active, so resetting zoom correctly clears the zoomed state. - When resetting zoom, `period: "1h"` and `polling: true` are now explicitly set in URL state to ensure the page returns to a live-polling relative range. - Fixed a race condition in `LogsVolumeChart` where Recharts fires a Bar `onClick` event immediately after a drag-select `mouseUp`, which was overwriting the dragged range with a single-bucket zoom. A `suppressNextBarClickRef` ref is set during drag completion and cleared on the next bar click to suppress the spurious event. - [x] Bug fix - [x] Feature - [x] UI (React) 1.

## Summary
This PR refactors the semantic cache plugin to simplify its internal state management, improves cache lookup correctness, and adds a new `cache_hit_types` filter to the logs API and UI. The direct cache lookup path is now a single deterministic point-fetch by a UUIDv5 `directCacheID` (replacing the previous dual-path of chunk lookup + legacy metadata scan), and several context keys are consolidated. The UI gains a "Local Caching" filter sidebar section and cache hit type badges in the log detail view.
## Changes
- **Semantic cache plugin refactor:**
- Replaced the dual direct-search path (`performDirectChunkLookup` + `performLegacyDirectSearch`) with a single `performDirectSearch` that does an O(1) `GetChunk` by deterministic `directCacheID` (UUIDv5 derived from provider, model, cacheKey, requestHash, paramsHash).
- `generateDirectCacheID` now returns an error instead of silently falling back to a string concatenation, making failures explicit.
- `request_hash` is no longer stored as a top-level metadata field; it is encoded into the `directCacheID` instead.
- Reduced context keys from ~10 to 4 (`directCacheIDKey`, `paramsHashKey`, `embeddingsKey`, `embeddingsInputTokensKey`), removing stale keys like `requestIDKey`, `requestHashKey`, `isCacheHitKey`, and `cacheHitTypeKey`.
- `shouldSkipCaching` is extracted into its own method; cache-hit detection now reads `CacheDebug.CacheHit` from the response rather than a context flag.
- `buildUnifiedMetadata` no longer accepts `requestHash` as a parameter.
- `addSingleResponse` renamed to `addNonStreamingResponse`.
- `StreamAccumulator` fields `HasError`, `FinalTimestamp`, and `FinishReason` on `StreamChunk` are removed; error streams are handled by early return in `PostLLMHook`.
- Streaming replay goroutine now guards every send with `ctx.Done()` to prevent goroutine leaks on dropped consumers.
- A background `runStreamCleanupLoop` goroutine (started by `Init`, stopped by `Cleanup` via `stopCh`) replaces the one-shot cleanup call, periodically reaping stale stream accumulators.
- `buildResponseFromResult` now accepts `threshold`, `similarity`, and `inputTokens` as pointers, and `attachCacheDebug` is extracted as a shared helper for both streaming and non-streaming paths.
- `isExpiredEntry` is extracted as a standalone function.
- `chunkSortKey` replaces the large inline sort comparator in `processAccumulatedStream`.
- Tools, stop sequences, modalities, include lists, and other order-insensitive set fields are now hashed with `hashSortedSet` / `sortedStringSet` to prevent MCP's randomized map iteration from perturbing the request hash.
- `extractAttachmentsForCaching` is extracted so attachment URLs are included in the cache key metadata rather than the embedding text.
- `extractTextForEmbedding` no longer returns a `paramsHash`; callers compute it once via `buildRequestMetadataForCaching` + `hashMap`.
- `generateEmbedding` moved from `utils.go` to `search.go`.
- `generateRequestHash` now accepts prebuilt metadata to avoid recomputing it.
- `removeField` no longer mutates the input slice's backing array.
- Added `PronunciationDictionaryLocators`, `TimestampGranularities`, `Include`, `AdditionalFormats`, and `InputImages` to their respective parameter metadata extractors.
- Public context key names changed from `semantic_cache_*` to `semantic_cache-*` (underscore → hyphen separator after the plugin prefix).
- `SelectFields` no longer includes `request_hash`.
- `VectorStoreProperties` no longer includes a `request_hash` entry.
- `CacheByModel` and `CacheByProvider` default-value log messages added.
- **Log filtering — `cache_hit_types`:**
- Added `CacheHitTypes []string` to `SearchFilters` in `framework/logstore/tables.go`.
- `applyFilters` in `rdb.go` applies a JSON path filter on `cache_debug` for both SQLite (`json_extract`) and PostgreSQL (`substring` regex) dialects, restricted to the allowlist `["direct", "semantic"]`.
- `canUseMatViewFilters` excludes queries with `CacheHitTypes` set from the materialized-view fast path.
- HTTP handlers (`getLogs`, `getLogsStats`, `parseHistogramFilters`) parse a `cache_hit_types` comma-separated query parameter.
- **UI:**
- Added a "Local Caching" filter section to `LogsFilterSidebar` with checkboxes for "Direct cache" and "Semantic cache".
- `cache_hit_types` is added to URL state, filter state, and the `buildFilterParams` API helper.
- Log detail view shows "Direct Cache" (indigo) and "Semantic Cache" (rose) badges based on `cache_debug.hit_type`.
- Plugins form now filters the provider dropdown to embedding-capable providers only (`EmbeddingSupportedProviders` for built-ins; `custom_provider_config.allowed_requests.embedding` for custom providers), shows an error message when no embedding provider is configured, and disables the toggle accordingly.
- Embedding model input replaced with `ModelMultiselect` (single-select mode) scoped to the selected provider.
- Provider dropdown clears the embedding model when the provider changes.
- Provider icons rendered in the provider dropdown.
- `EmbeddingSupportedProviders` constant added to `ui/lib/constants/logs.ts`.
- **Misc:**
- HTTP request logging in `CorsMiddleware` and an auth debug log are commented out.
- `transports/bifrost-http/v1.5.x` added to `.gitignore`.
- Minor formatting fixes in `core/schemas/bifrost.go` and `framework/modelcatalog/sync.go`.
- Missing newline at end of `sync.go` added.

- Configure the semantic cache plugin with a direct and/or semantic cache type and verify that cache hits are recorded with the correct `hit_type` in `cache_debug`.
- Query `/logs?cache_hit_types=direct` and `/logs?cache_hit_types=semantic` and confirm only matching entries are returned.
- In the UI, open the logs filter sidebar and verify the "Local Caching" section appears with "Direct cache" and "Semantic cache" checkboxes that correctly filter the log list.
- Open a log detail for a cache hit and confirm the appropriate badge ("Direct Cache" or "Semantic Cache") is displayed.
- In the plugins form, verify that only embedding-capable providers appear in the provider dropdown and that the embedding model field uses the model multiselect.
## Breaking changes
- [x] Yes
The public semantic cache context key names have changed from `semantic_cache_*` to `semantic_cache-*`. Any caller setting `CacheKey`, `CacheTTLKey`, `CacheThresholdKey`, `CacheTypeKey`, or `CacheNoStoreKey` via the old string values will no longer be recognized by the plugin. Update all call sites to use the exported constants from the plugin package rather than raw string literals.
`request_hash` is no longer stored as a top-level metadata field in the vector store. Existing cache entries written by prior versions will not be found by the new direct-search path (they will be treated as misses and re-populated).
`ClearCacheForRequestID` is documented as currently broken for entries written by the new direct-search path; callers should not rely on it until the TODO is resolved.
## Related issues
N/A
## Security considerations
The `CacheHitTypes` filter allowlists values to `"direct"` and `"semantic"` before interpolating them into SQL, preventing arbitrary input from reaching the JSON path expression.

## Summary Replaces the separate `PluginsForm` component with a fully self-contained `CachingView` that introduces a first-class **Direct / Direct + Semantic** mode toggle for the local cache plugin. Previously, the UI only exposed provider-backed semantic cache settings and had no concept of direct-only (hash-based) caching as a distinct, supported mode. This rewrite makes direct-only mode the default and gates semantic configuration behind an explicit mode selection. ## Changes - Deleted `pluginsForm.tsx` and consolidated all local cache configuration logic directly into `cachingView.tsx`. - Introduced a `CacheMode` type (`"direct"` | `"semantic"`) with a tab-based picker. Direct-only mode requires no embedding provider; semantic mode adds vector similarity on top and requires a provider, model, and dimension. - The enable/disable toggle now immediately calls `updatePlugin` or `createPlugin` (for first-time setup) rather than deferring the enabled-state change to the Save button, decoupling the plugin lifecycle from config edits. - Added `inferMode` to derive the active mode from a saved config, `isEmptyConfig` to detect zero-value configs from the API, `buildPayload` to strip semantic-only fields when persisting a direct-only config, and `validateForSave` for inline validation surfaced before the user clicks Save. - Structural change warnings (provider/model/dimension drift vs. server state) are now shown only when the user has actually modified those fields, rather than permanently in semantic mode. - Removed the Zod `cacheConfigSchema` validation path in favor of the new `validateForSave` function. - Removed the effect that auto-seeded a default provider/model/dimension on first load, since direct-only mode no longer requires those fields. - Per-request override documentation expanded to include `x-bf-cache-key` and `x-bf-cache-no-store` with clearer descriptions. ## Type of change - [ ] Bug fix - [ ] Feature - [x] 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 || npm i pnpm build || npm run build ``` 1. Navigate to the Workspace → Config → Caching view. 2. Verify the page loads with **Direct only** selected by default and no provider/model/dimension fields visible. 3. Switch to **Direct + Semantic** and confirm provider, model, and dimension fields appear with inline validation. 4. Toggle caching on without a vector store configured and confirm the toggle is disabled. 5. Save a direct-only config and confirm the plugin is created/updated with `dimension: 1` and no provider fields. 6. Save a semantic config with a valid provider, model, and dimension and confirm the full payload is persisted. 7. Reload the page and confirm the saved mode and config are correctly hydrated. ## Screenshots/Recordings Before/after screenshots recommended showing the mode tab picker, the conditional semantic fields, and the structural change warning banner. ## Breaking changes - [x] Yes - [ ] No The `PluginsForm` component is removed.

…and plugin reloads (#3423) ## Summary The `CacheHandler` previously captured a reference to the `semantic_cache` plugin at boot time. This caused two bugs: (1) if the plugin was not present in `config.json` at startup, cache-clear routes were never registered, resulting in HTTP 405 for the entire process lifetime; (2) if the plugin was loaded or reloaded via `/api/plugins` after boot, the handler held a stale (or nil) pointer and would silently misbehave. Additionally, `GET /api/plugins/:name` was returning the raw plugin config without runtime status, causing the UI to see an empty status when refetching a single plugin. ## Changes - `CacheHandler` now accepts a `CacheClearerResolver` function instead of a concrete plugin pointer. The resolver is called on every cache-clear request, so plugin lifecycle changes via `/api/plugins` are always honored. - `CacheClearer` and `CacheClearerResolver` are exported so server wiring can supply the resolver without importing the plugin's concrete type. - Cache routes are registered unconditionally at startup. When no plugin is loaded, requests return HTTP 400 with a descriptive message instead of HTTP 405. - The server wiring in `RegisterAPIRoutes` uses a closure over `lib.FindPluginAs` to resolve the plugin per request, replacing the boot-time capture. - `getPlugin` now returns the same response shape as list/create/update (with runtime status merged in), fixing the empty status seen by `useGetPluginQuery` in the UI. - Tests cover the new "plugin not loaded" path for both `clearCache` and `clearCacheByKey`, and existing tests are updated to use the resolver-based constructor. ## Type of change - [x] Bug fix - [ ] Feature - [ ] Refactor - [ ] Documentation - [ ] Chore/CI ## Affected areas - [ ] Core (Go) - [x] Transports (HTTP) - [ ] Providers/Integrations - [x] Plugins - [ ] UI (React) - [ ] Docs ## How to test ```sh go test ./transports/bifrost-http/handlers/... go test ./transports/bifrost-http/... ``` 1. Start the server **without** `semantic_cache` in `config.json`. Issue `DELETE /api/cache/clear/{cacheId}` — expect HTTP 400 with `"semantic_cache plugin is not loaded"` (previously HTTP 405). 2. Load the `semantic_cache` plugin via `POST /api/plugins`. Repeat the request — expect the cache-clear to succeed. 3. Reload or remove the plugin via `PUT`/`DELETE /api/plugins`. Verify the handler reflects the new state on the next request without a server restart. 4. Issue `GET /api/plugins/{name}` for a loaded plugin and confirm the response includes runtime status fields, matching the shape returned by the list endpoint. ## Breaking changes - [x] Yes - [ ] No `NewCacheHandler` now accepts a `CacheClearerResolver` function instead of a `schemas.LLMPlugin`. Any caller constructing a `CacheHandler` directly must be updated to pass a resolver. ## Related issues ## Security considerations None.

…rch paths in semantic cache (#3424) ## Summary Fixes several correctness issues in the semantic cache plugin's `PostLLMHook` and related helpers: cache telemetry (`cache_debug`) was previously invisible to callers using `no-store`, cache-hit replay detection was fragile, non-positive per-request TTL overrides could silently kill cache writes, and requests with a `cache_type` header narrowed to a path the plugin cannot serve would still produce orphan cache entries. ## Changes - **Early exit for unsupported search paths in `PreLLMHook`**: When `resolveCacheTypes` resolves to a path the plugin cannot actually serve (e.g. `x-bf-cache-type=semantic` against a direct-only plugin, or an unknown header value), the hook now clears cache state and returns early instead of proceeding to generate an embedding or write an orphan entry under a random request UUID that no future read can match. - **Separated cache-hit replay handling from write-skip logic**: The `shouldSkipCaching` method (which conflated cache-hit detection with write-skip conditions) is replaced by `shouldSkipCacheWrite`. Cache-hit replay is now handled as a dedicated early return in `PostLLMHook` before any telemetry stamping, while `shouldSkipCacheWrite` gates only the write decision after telemetry is already stamped. This ensures `cache_debug` is always populated for callers using `no-store` or large-payload modes. - **Telemetry stamped before write decision**: `stampCacheDebugForMiss` is now called before `shouldSkipCacheWrite` is consulted, so observability is not conditional on whether the entry is ultimately written. - **Non-positive TTL overrides fall back to plugin default**: `resolveTTL` now treats a zero or negative per-request TTL override as "use default" rather than applying it, which would have set `expires_at=now` and silently discarded the cache write. - **Cleaned up stale comments**: Removed an outdated ordering constraint comment in `PostLLMHook` that no longer applies after the restructuring. - **Tests updated**: Test cases for `shouldSkipCaching` are renamed and updated to reflect the new `shouldSkipCacheWrite` contract. The cache-hit replay test case is removed from this suite (it is now an early return in `PostLLMHook`, not a condition inside the helper). A new default-is-false test is added. ## Type of change - [x] Bug fix - [ ] Feature - [x] Refactor - [ ] Documentation - [ ] Chore/CI ## Affected areas - [ ] Core (Go) - [ ] Transports (HTTP) - [ ] Providers/Integrations - [x] Plugins - [ ] UI (React) - [ ] Docs ## How to test ```sh go test ./plugins/semanticcache/... ``` Validate the following scenarios: - A request with `x-bf-cache-type=semantic` against a plugin configured with `Provider=""` or `Dimension=1` should log a warning and skip caching entirely — no orphan entry should appear in the store. - A request with `Cache-Control: no-store` should still produce a populated `cache_debug` field in the response with `cache_hit=false`. - A per-request TTL override of `0s` should fall back to the plugin's configured default TTL and not silently discard the cache write. ## Breaking changes - [x] No ## Security considerations None. ## 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 Adds a standalone end-to-end test suite for the `semantic_cache` plugin under `tests/semanticcache`. The suite validates the full caching lifecycle against a live Bifrost instance — plugin creation/teardown, cache miss/hit assertions, cross-provider behavior, streaming, and log cross-checking — without provisioning any infrastructure itself. ## Changes - **`e2e_test.go`** — `TestMain` entry point: loads config, initializes the report directory, checks Bifrost reachability, enforces plugin-absent precondition (with `RUN_FORCE=1` auto-delete), runs all phases, and performs best-effort teardown on exit. - **`preconditions_test.go`** — Phase 0 checks: Bifrost reachable, OpenAI configured, optional providers (Gemini, Anthropic) present with warnings if absent. - **`http_test.go`** — HTTP helpers for all request types: chat completions (streaming and non-streaming), text completions, embeddings, image generation, and the Responses API. Each helper dumps full request/response bodies to the report directory for forensics. - **`plugin_test.go`** — Plugin lifecycle helpers (`pluginCreate`, `pluginUpdate`, `pluginDelete`, `pluginGet`) mirroring the exact wire format the UI sends to `/api/plugins`. - **`assert_test.go`** — Assertion helpers (`assertMiss`, `assertHit`, `assertNoCacheDebug`, `assertSameCacheID`, `assertDifferentCacheID`) plus a configurable async write-settle wait (`SC_WRITE_SETTLE_MS`) to account for the plugin's async PostLLMHook store write. - **`cache_test.go`** — Cache management helpers (`clearByCacheID`, `clearByCacheKey`) wrapping the `/api/cache/clear/*` endpoints. - **`logs_crosscheck_test.go`** — Cross-checks the persisted log row's `cache_debug` against the in-flight response stamp, with polling to handle Bifrost's async logging pipeline and float epsilon tolerance for JSON encoder differences. - **`fixtures_test.go`** — Hand-curated paraphrase pairs for Phase 2 semantic cases, designed to land well above (canonical→paraphrase) or well below (canonical→unrelated) the default 0.8 similarity threshold. - **`log_test.go`** — Structured per-run logging to `reports/<UTC-timestamp>/run.log` with optional `TRAIL_SESSION_ID` stamping for trail integration. - **`go.mod`** — Standalone module (`github.com/maximhq/bifrost/tests/semanticcache`), consistent with the `tests/governance` pattern, excluded from the repo's `go.work`. - **`README.md`** — Documents prerequisites, env vars, run commands, trail integration, and report output format. - **`.gitignore`** — Excludes `reports/` and `*.log` from version control. Notable design decisions: the suite is intentionally verify-only (no infrastructure provisioning), uses a dedicated vector store namespace (`BifrostSemanticCachePluginE2E`) to isolate test data, and writes full wire-level request/response artifacts per step to support post-mortem debugging without re-running. ## Type of change - [ ] Bug fix - [ ] Feature - [ ] Refactor - [ ] Documentation - [x] Chore/CI ## Affected areas - [ ] Core (Go) - [ ] Transports (HTTP) - [ ] Providers/Integrations - [x] Plugins - [ ] UI (React) - [ ] Docs ## How to test Requires a running Bifrost instance with Weaviate configured, OpenAI (required), and optionally Gemini and Anthropic providers. ```sh cd tests/semanticcache # All phases GOWORK=off go test -v ./... # Single phase GOWORK=off go test -v -run TestPhase1_DirectOnly ./... # Auto-delete any pre-existing plugin row before run RUN_FORCE=1 GOWORK=off go test -v ./... # Keep plugin after run for post-mortem inspection RUN_KEEP_PLUGIN=1 GOWORK=off go test -v ./... ``` Environment variables: | Variable | Default | Purpose | |---|---|---| | `BIFROST_URL` | `http://localhost:8080` | Bifrost base URL | | `SC_CHAT_MODEL_OPENAI` | `openai/gpt-4o-mini` | OpenAI chat model | | `SC_CHAT_MODEL_OPENAI_ALT` | `openai/gpt-4o` | Alternate OpenAI model for cache-by-model cases | | `SC_EMBED_MODEL_OPENAI` | `text-embedding-3-small` | Embedding model for Phase 2 | | `SC_CHAT_MODEL_GEMINI` | `gemini/gemini-2.5-flash` | Gemini chat model | | `SC_CHAT_MODEL_ANTHROPIC` | `anthropic/claude-haiku-4-5` | Anthropic chat model | | `SC_NAMESPACE` | `BifrostSemanticCachePluginE2E` | Vector store namespace | | `SC_WRITE_SETTLE_MS` | `500` | Async write settle wait in ms | | `RUN_FORCE` | unset | `1` to delete pre-existing plugin before run | | `RUN_KEEP_PLUGIN` | unset | `1` to skip teardown on exit | | `TRAIL_SESSION_ID` | unset | Stamped onto every log line for trail integration | ## Screenshots/Recordings N/A ## Breaking changes - [x] No ## Related issues N/A ## Security considerations No secrets are stored in the test suite.

## Summary Adds a comprehensive end-to-end test suite (`TestDirect`) for the semantic cache plugin operating in direct-only mode. The suite covers 55 test cases (plan §1.1–1.55) validating cache hit/miss behavior, key isolation, TTL handling, config flag mutations, normalization, streaming, multi-endpoint support, parameter hashing, tool definitions, and cache management operations. ## Changes - Introduces `tests/semanticcache/direct_test.go` with `TestDirect`, covering: - **Basic hit/miss and key isolation** (1.1, 1.2, 1.3, 1.4) - **`cache_by_model` and `cache_by_provider` flag behavior** (1.5–1.8), including serial config-mutation cases that restore baseline via `t.Cleanup` - **`exclude_system_prompt` flag** (1.9, 1.10) - **Conversation threshold boundary conditions** (1.11, 1.12) - **TTL expiry, per-request TTL override, invalid TTL fallback, and zero/negative TTL fallback** (1.13, 1.14, 1.15, 1.54) - **`no-store` header semantics**, including case-sensitivity and explicit `false` value (1.16, 1.17, 1.45, 1.46) - **`cache-type` header behavior** in direct-only mode, including the `semantic` header bug case (1.18, 1.19) - **Streaming SSE**: hit/miss, chunk replay order, and non-final chunk cache_debug absence (1.24, 1.25, 1.47) - **Multi-endpoint coverage**: text completions, responses API, embeddings, and image generation (1.20–1.23) - **Input normalization**: case folding, whitespace trimming, Unicode, and large prompts (1.26–1.29) - **Image attachment hashing**: same URL hits, different URL misses (1.30, 1.31) - **Edge cases**: nil content messages, empty messages array, unknown cache ID deletion (1.42, 1.43, 1.40) - **Parameter hash isolation**: temperature, top_p, seed, max_tokens, top_logprobs, tools (order-independent and name-change), prompt_cache_key, service_tier, store flag (1.32–1.37, 1.48–1.52) - **Cache management**: clear by cache ID, clear by key (1.38, 1.39) - **Plugin status round-trip** via GET (1.44) - **`/api/logs` cross-check**: verifies persisted `cache_debug` matches in-flight response stamp (1.55) - **`responses` API `previous_response_id` isolation** (1.53) - **Threshold header no-op in direct-only mode** (1.41) - Adds helper functions: `simpleChat`, `chatWithSystem`, `chatWithImage`, `restoreDirectBaseline`, `assertHitAndReturnCacheDebug` - Establishes a parallelism contract: cases that mutate plugin config run serially (no `t.Parallel()`); all others run concurrently with unique cache keys to prevent collisions ## Type of change - [ ] Bug fix - [ ] Feature - [ ] Refactor - [ ] Documentation - [x] Chore/CI ## Affected areas - [ ] Core (Go) - [ ] Transports (HTTP) - [ ] Providers/Integrations - [x] Plugins - [ ] UI (React) - [ ] Docs ## How to test ```sh # Run the full direct-mode suite go test ./tests/semanticcache/... -run TestDirect -v -timeout 300s # Skip the expensive image generation case SC_SKIP_IMAGE_GEN=1 go test ./tests/semanticcache/... -run TestDirect -v -timeout 300s ``` Required environment variables (same as the broader semantic cache e2e suite): - `OPENAI_MODEL` — primary OpenAI-compatible model (e.g. `openai/gpt-4o-mini`) - `OPENAI_MODEL_ALT` — secondary model for cross-model isolation cases - `OPENAI_EMBED` — embedding model name (e.g. `text-embedding-3-small`) - `ANTHRO_MODEL` — (optional) Anthropic model; cases 1.7 and 1.8 skip if unset - `SC_SKIP_IMAGE_GEN=1` — (optional) skip case 1.23 to avoid DALL-E costs ## Screenshots/Recordings N/A — test-only change. ## Breaking changes - [x] No ## Related issues ## Security considerations No new auth, secrets, or PII surface.

## Summary Adds a comprehensive integration test suite for the semantic cache mode (Phase 2), covering the full lifecycle of semantic similarity-based cache hits and misses using Weaviate as the vector store and OpenAI's `text-embedding-3-small` as the embedding model. This suite validates that the semantic cache behaves correctly across a wide range of real-world scenarios, complementing the existing direct-mode (Phase 1) tests. ## Changes - Added `TestParaphraseFixtures` to pre-flight all paraphrase pairs against the live embedding model, asserting cosine similarity thresholds before any semantic cache cases run. This prevents flaky downstream failures caused by borderline fixture pairs. - Added `TestSemantic` containing 44 sub-cases (2.1–2.44) covering: - Semantic hit on paraphrase, miss on unrelated content - Per-request threshold overrides (relax, tighten, clamp above/below valid range) - `x-bf-cache-type` header forcing direct-only or semantic-only lookup paths - Cache key and model/provider isolation in semantic mode - `cache_by_model=false` and `cache_by_provider=false` cross-model/cross-provider hits - Streaming replay of semantic hits, including tool call preservation - TTL expiry, per-request TTL, TTL=0 fallback, and `no-store` header semantics - Namespace isolation and dimension-change silent miss behavior - Embedding endpoint bypass (semantic search skipped for `/v1/embeddings`) - Image generation and Responses API semantic hits - Text completion semantic hits - Gemini provider with OpenAI embedding provider - `params_hash` isolation (temperature, service tier, store flag, prompt cache key, previous response ID) - `exclude_system_prompt` flag effect on semantic matching - Conversation message threshold skipping semantic search - Attachment URL changes causing misses - `cache_debug` field presence and correctness on hits and misses, including log endpoint cross-check - Streaming chunk-level `cache_debug` placement (final chunk only) - Serial (non-parallel) cases that mutate plugin config restore baseline via `t.Cleanup` to avoid test pollution. - A dedicated Weaviate namespace (`cfg.Namespace + "Semantic"`) is used to avoid dimension conflicts with the Phase 1 direct-mode namespace. ## Type of change - [ ] Bug fix - [ ] Feature - [ ] Refactor - [ ] Documentation - [x] Chore/CI ## Affected areas - [ ] Core (Go) - [ ] Transports (HTTP) - [ ] Providers/Integrations - [x] Plugins - [ ] UI (React) - [ ] Docs ## How to test ```sh # Run fixture pre-flight (requires OpenAI embedding access) go test ./tests/semanticcache/... -run TestParaphraseFixtures -v # Run full semantic suite go test ./tests/semanticcache/... -run TestSemantic -v -timeout 10m # Skip fixture verification if embedding access is unavailable SC_SKIP_FIXTURE_VERIFY=1 go test ./tests/semanticcache/... -run TestSemantic -v -timeout 10m # Skip image generation cases if DALL-E is unavailable SC_SKIP_IMAGE_GEN=1 go test ./tests/semanticcache/... -run TestSemantic -v -timeout 10m ``` Required environment/config: - `cfg.OpenAIEmbed` — embedding model name (e.g. `text-embedding-3-small`) - `cfg.OpenAIModel` / `cfg.OpenAIModelAlt` — chat models for isolation tests - `cfg.AnthroModel` — optional; skipped if empty (case 2.13) - `cfg.GeminiModel` — optional; skipped if empty (case 2.28) - `cfg.Namespace` — base Weaviate namespace; suite appends `Semantic` suffix - `SC_SKIP_FIXTURE_VERIFY=1` — skip embedding pre-flight - `SC_SKIP_IMAGE_GEN=1` — skip DALL-E case ## Screenshots/Recordings N/A ## Breaking changes - [x] No ## Related issues N/A ## Security considerations No new auth, secrets, or PII handling introduced.

## Summary
Adds an end-to-end lifecycle test for the semantic cache plugin, covering the full disable → re-enable → delete → recreate flow and asserting that namespace data persists across each state transition.
## Changes
- Introduces `TestLifecycle` in `tests/semanticcache/lifecycle_test.go`, which runs 10 serial subtests (3.1–3.10) exercising the plugin's lifecycle state machine:
- **3.1** – Disabling the plugin via PUT sets `enabled=false` and `status=disabled`
- **3.2** – Requests while disabled bypass the cache pipeline entirely (no `cache_debug` header)
- **3.3 / 3.4** – Cache-clear endpoints (`/api/cache/clear/{id}` and `/api/cache/clear-by-key/{k}`) return HTTP 400 when the plugin is not loaded
- **3.5** – Re-enabling via PUT restores `enabled=true` and `status=active`
- **3.6** – Entries written before disable are still queryable after re-enable
- **3.7** – DELETE removes both the DB row and the in-memory plugin instance
- **3.8** – Requests after delete bypass the cache pipeline (no `cache_debug` header)
- **3.9** – Recreating the plugin with the same config succeeds and surfaces `status=active`
- **3.10** – Entries written before delete are still queryable after recreate, validating the namespace-persistence contract introduced by the removal of `CleanUpOnShutdown`
- Tests are intentionally serial (no `t.Parallel()`) because each subtest mutates globally shared plugin lifecycle state
- A `t.Cleanup` handler performs best-effort key clearing regardless of which lifecycle state the plugin is left in at teardown

## Summary Improves the Qdrant vector store integration by raising the gRPC receive message size limit to 64 MB (configurable), and adds dimension mismatch detection on `CreateNamespace` for Qdrant and Redis to surface clear errors when an existing collection/index has a different vector dimension than what the config expects. ## Changes - Added a `max_recv_msg_size_mb` field to `QdrantConfig` (default: 64 MB) that sets the gRPC `MaxCallRecvMsgSize` dial option. The previous 4 MB gRPC default caused silent failures when caching large payloads such as base64-encoded image generation responses. - Added dimension validation in `QdrantStore.CreateNamespace`: if the collection already exists and its vector dimension differs from the requested dimension, an actionable error is returned instead of silently proceeding. - Added the same dimension validation in `RedisStore.CreateNamespace` using `FT.INFO` attribute metadata. - Added a `Configuration Reference` table to the Qdrant integration docs covering all supported fields, their types, defaults, and descriptions. - Added `max_recv_msg_size_mb` to the JSON config schema with a minimum of 1 and a default of 64. - Promoted `google.golang.org/grpc` from an indirect to a direct dependency in `go.mod` since it is now explicitly used in `qdrant.go`. ## Type of change - [ ] Bug fix - [x] Feature - [ ] Refactor - [ ] Documentation - [ ] Chore/CI ## Affected areas - [x] Core (Go) - [x] Transports (HTTP) - [ ] Providers/Integrations - [ ] Plugins - [ ] UI (React) - [x] Docs ## How to test ```sh # Run framework tests cd framework go test ./vectorstore/... # Verify Qdrant with a large payload (e.g. base64 image response) # Configure a Qdrant vector store with max_recv_msg_size_mb unset (defaults to 64) # and cache an image generation response — confirm no gRPC message size error. # Verify dimension mismatch error # Point Bifrost at an existing Qdrant collection or Redis index with dimension N, # set vector_store_namespace to that collection and configure dimension M (M ≠ N). # Expected: startup fails with a clear error message indicating the mismatch and # instructing the user to rename the namespace or drop the collection manually. ``` New config field for Qdrant: | Field | Type | Default | Description | |---|---|---|---| | `max_recv_msg_size_mb` | integer | `64` | gRPC max receive message size in MB.

## Summary `RunSingleMigration` previously always used `migrator.DefaultOptions`, making it impossible for callers to supply custom migrator options. This PR adds an optional `*migrator.Options` parameter so downstream consumers (e.g. bifrost-enterprise, plugins) can pass their own options when needed, while all existing internal callers pass `nil` to retain the default behavior. ## Changes - Added an `options *migrator.Options` parameter to `RunSingleMigration`; when `nil` is passed, `migrator.DefaultOptions` is used as before - Updated all internal call sites to pass `nil`, preserving existing behavior ## Type of change - [ ] Bug fix - [ ] Feature - [x] Refactor - [ ] Documentation - [ ] Chore/CI ## Affected areas - [x] Core (Go) - [ ] Transports (HTTP) - [ ] Providers/Integrations - [x] Plugins - [ ] UI (React) - [ ] Docs ## How to test ```sh go test ./framework/configstore/... ``` Verify that all existing migrations continue to run successfully with `nil` options, and that a custom `*migrator.Options` value is correctly applied when provided. ## Breaking changes - [x] Yes - [ ] No `RunSingleMigration` is a public function.

## Summary This PR cuts the `v1.5.11` / `v1.3.11` release across core, framework, and all plugins, and introduces a new Claude skill (`release-checklist`) for pre-release migration safety auditing. ## Changes - **`release-checklist` skill** — Adds `.claude/skills/release-checklist/SKILL.md`, a read-only pre-release audit tool that scans Go-defined database migrations changed in a release for high-scale deadlock/lock-contention risks and boot-time-blocking operations. It produces a structured `PASS`/`WARN`/`FAIL` report with a concrete remediation plan per finding. The skill is designed to grow via an extensible Checks Registry. - **Version bumps** — `core` → `1.5.11`, `framework` → `1.3.11`, `transports` → `1.5.3`, `plugins/governance` → `1.5.11`, `plugins/logging` → `1.5.11`, `plugins/semanticcache` → `1.5.11`, `plugins/otel` → `1.2.11`, `plugins/maxim` → `1.6.11`, `plugins/prompts` → `1.0.11`, and remaining plugins bumped accordingly. - **Changelogs populated** — All per-package changelogs updated with the full set of features and fixes shipping in this release. Key highlights in this release: - Temporary access tokens for scoped, time-limited API access - MCP per-user OAuth flow refactor - Bedrock Mantle inference engine support - Azure Realtime provider with enriched session tracking - Direct access control (DAC) and virtual key rotation - Cluster-aware log metadata and per-node usage aggregation - Feature flag framework - Config-hash-based file value override of DB on restart - Semantic cache plugin rewrite - Numerous streaming stability, Bedrock, Anthropic, and Gemini fixes - AWS SDK and dependency security updates ## Type of change - [ ] Bug fix - [ ] Feature - [ ] Refactor - [ ] Documentation - [x] Chore/CI ## Affected areas - [x] Core (Go) - [x] Transports (HTTP) - [x] Providers/Integrations - [x] Plugins - [x] UI (React) - [ ] Docs ## How to test ```sh # Verify version files reflect the new release cat core/version # expect 1.5.11 cat framework/version # expect 1.3.11 cat transports/version # expect 1.5.3 # Core/Transports go test ./... ``` To exercise the new `release-checklist` skill, invoke it via Claude with: ``` /release-checklist origin/dev...HEAD ``` Expected output: a structured report with `PASS`/`WARN`/`FAIL` per check and a Remediation Plan table for any findings. ## Screenshots/Recordings N/A ## Breaking changes - [ ] Yes - [x] No ## Related issues #3603, #3565, #3489, #3334, #3335, #3435, #3554, #3590, #3444, #3198, #3581, #3610, #3599, #3567, #3382, #3461 and others listed in the changelogs. ## Security considerations - AWS SDK and dependency security updates are included (#3461). - `FullyRedacted()` for proxy passwords and `MarshalForStorage()` for `ProxyConfig` prevent partial secret leakage in API responses (#3445). - The `release-checklist` skill is strictly read-only and never modifies files. ## Checklist - [x] I read `docs/contributing/README.md` and followed the guidelines - [x] I added/updated tests where appropriate - [x] I updated documentation where needed - [x] I verified builds succeed (Go and UI) - [ ] I verified the CI pipeline passes locally if applicable
## Summary This PR addresses several reliability issues in LLM integration tests and fixes an incorrect role assignment for Gemini function/tool responses. It also resolves a stream cancellation race condition and updates stale test configuration values. ## Changes - **Gemini role fix**: Corrected the role assigned to pending function/tool response parts from `"model"` to `"user"` in both the chat completions (`utils.go`) and responses (`responses.go`) Gemini converters. Gemini requires function responses to be sent under the `"user"` role, not `"model"`. - **Token limit increases**: Raised `MaxCompletionTokens` and `MaxOutputTokens` across streaming, tool calling, and end-to-end tests to prevent responses from being truncated before completion, which was causing intermittent test failures. - **OpenRouter timeout increase**: Increased the default request timeout for OpenRouter from 120s to 300s to account for its variability as a proxy service. - **Stream cancellation guard**: Added a check for `BifrostContextKeyConnectionClosed` before attempting to close the body stream on context cancellation, preventing a nil-dereference in fasthttp's connection cleaner when the connection is already closed. - **OpenAI audio model update**: Updated the `ChatAudioModel` in the OpenAI test config from `gpt-4o-mini-audio-preview` to `gpt-audio-mini`. - **HuggingFace image tests disabled**: Disabled image generation and image edit test scenarios for HuggingFace as they are not currently supported. ## Type of change - [x] Bug fix - [ ] Feature - [ ] Refactor - [ ] Documentation - [ ] Chore/CI ## Affected areas - [x] Core (Go) - [ ] Transports (HTTP) - [x] Providers/Integrations - [ ] Plugins - [ ] UI (React) - [ ] Docs ## How to test ```sh go test ./core/providers/gemini/... go test ./core/providers/openai/... go test ./core/providers/huggingface/... go test ./core/internal/llmtests/... go test ./core/providers/utils/... ``` Run the end-to-end and streaming tests against OpenRouter and Gemini providers and verify that tool call conversations complete without truncation errors and that stream cancellation no longer causes nil-dereference panics. ## Breaking changes - [ ] Yes - [x] No ## Related issues ## Security considerations None. ## 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 Fixes two distinct issues: (1) Gemini 2.5 and earlier models reject requests that combine function-calling tools with `responseMimeType: "application/json"` (structured output / JSON mode). This PR drops the `responseMimeType` field for those models when tools are present, while still forwarding `responseJsonSchema` so schema-constrained output continues to work. Gemini 3.x supports the combination and is left unchanged. (2) Malformed JSON request bodies now return HTTP 400 with `Connection: close`, preventing the server from leaving keep-alive sockets open after a parse failure. ## Changes - In `convertParamsToGenerationConfig`, clear `ResponseMIMEType` when tools are present and the model is older than Gemini 3.x, matching the Gemini API's documented constraint. - Extracted a `parseJSONRequestBody` helper that wraps `sonic.Unmarshal` with a descriptive error including the body length. - Both the custom `RequestParser` path and the default JSON parsing path now call `ctx.SetConnectionClose()` and return HTTP 400 (via `newBifrostErrorWithCode`) on parse failure, rather than leaving the status code unset and the connection open. - Added `TestStructuredOutputWithToolsConflict` covering four scenarios: Gemini 2.5 with tools + `json_object`, Gemini 2.5 with tools + `json_schema`, Gemini 3.x with tools + `json_schema`, and Gemini 2.5 with `json_schema` but no tools. - Added router-level tests verifying that parse failures set 400 and `Connection: close`, that valid keep-alive requests reuse the socket, and that a malformed request closes the socket and makes subsequent reads fail. ## Type of change - [x] Bug fix - [ ] Feature - [ ] Refactor - [ ] Documentation - [ ] Chore/CI ## Affected areas - [x] Core (Go) - [x] Transports (HTTP) - [x] Providers/Integrations - [ ] Plugins - [ ] UI (React) - [ ] Docs ## How to test ```sh go test ./core/providers/gemini/... -run TestStructuredOutputWithToolsConflict -v go test ./transports/bifrost-http/integrations/... -run "TestCreateHandler_|TestOpenAIChatStructuredOutput" -v go test ./... ``` Expected: all new and existing tests pass. Specifically: - `Gemini2.5_ToolsWithJSONObject_DropsResponseMimeType` and `Gemini2.5_ToolsWithJSONSchema_DropsResponseMimeType` assert `ResponseMIMEType` is empty. - `Gemini3_ToolsWithJSONSchema_KeepsResponseFormat` asserts `ResponseMIMEType` is `"application/json"`. - `TestCreateHandler_ParseFailureClosesKeepAliveSocket/malformed_request_closes_the_socket` asserts `resp.Close == true` and that a subsequent read on the same connection returns an error. ## Breaking changes - [ ] Yes - [x] No ## Related issues ## Security considerations None beyond the connection-close fix, which prevents a client from potentially reusing a connection that was left in an ambiguous state after a bad request. ## 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
