This commit overhauls the dashboard styling to achieve a 'retro terminal' look matching the Gruvbox color palette. Changes include switching the global font to JetBrains Mono/Fira Code, removing rounded corners on all major elements (cards, buttons, inputs, modals, badges), and replacing modern soft shadows with sharp, hard-offset block shadows.
This commit adds a proper flexbox layout to the '.card-actions' CSS class. Previously, action buttons (like Export and Refresh on the Analytics page) were bunching up because they lacked a flex container with appropriate gap and wrapping rules. It also updates the '.card-header' to wrap gracefully on smaller screens.
This commit corrects the CSS for the login form's floating labels. Previously, the label floated too high and had a solid background that contrasted poorly with the input box. The label now floats exactly on the border line and uses a linear-gradient to seamlessly blend the card background into the input background, fixing the 'misframed' appearance.
This commit enhances the Model Registry UI by adding dropdown filters for Provider, Modality (Text/Image/Audio), and Capabilities (Tool Calling/Reasoning) alongside the existing text search. The filtering logic has been refactored to be non-destructive and apply instantly on the client side.
This commit modifies the /api/models endpoint so that when fetching 'used models' for the Cost Management view, it accurately pairs each model with the exact provider it was routed through (by querying SELECT DISTINCT provider, model FROM llm_requests). Previously, it relied on the global registry's mapping, which could falsely attribute usage to unconfigured or alternate providers.
This commit adds 'unsafe-inline' to the script-src CSP directive. The frontend dashboard heavily relies on inline event handlers (e.g., onclick=...) dynamically generated via template literals in its vanilla JavaScript architecture. Without this directive, modern browsers block these handlers, rendering interactive elements like the Config button completely inert.
This commit updates the Content Security Policy to allow scripts, styles, and fonts from cdn.jsdelivr.net, cdnjs.cloudflare.com, fonts.googleapis.com, and fonts.gstatic.com. This resolves the 'luxon is not defined' error and fixes the broken charts by allowing Chart.js, Luxon, FontAwesome, and Google Fonts to load properly in the dashboard.
This commit resolves the 'Failed to load statistics' issue where dashboard panels appeared empty. The dashboard makes 10+ concurrent API requests on load, which was instantly triggering the global rate limit's burst threshold (default 10). Internal dashboard endpoints are now exempt from this strict LLM-traffic rate limiting since they are already secured by admin authentication.
This commit updates the frontend API client to intercept authentication errors (like a stale session after a server restart) and immediately clear the local storage and show the login screen. It also adds an onsubmit handler to the login form in index.html to prevent the browser from defaulting to a GET request that puts credentials in the URL if JavaScript fails to initialize or encounters an error.
This commit adds the missing auth::require_admin check to all analytics, system info, and configuration list endpoints. It also improves error logging in the usage summary handler to aid in troubleshooting 'Failed to load statistics' errors.
Updated OpenAI Responses API to use a structured input format (array of objects) for better compatibility. Added a proactive error probe to chat_responses_stream to capture and log API error bodies on failure.
This commit adds support for the OpenAI Responses API in both streaming and non-streaming modes. It also implements proactive routing for gpt-5 and codex models and cleans up unused 'session' variable warnings across the dashboard source files.
This commit introduces:
- AES-256-GCM encryption for LLM provider API keys in the database.
- HMAC-SHA256 signed session tokens with activity-based refresh logic.
- Standardized frontend XSS protection using a global escapeHtml utility.
- Hardened security headers and request body size limits.
- Improved database integrity with foreign key enforcement and atomic transactions.
- Integration tests for the full encrypted key storage and proxy usage lifecycle.
This commit fixes the Gemini API 'Invalid value at thought_signature' error by ensuring synthetic 'call_' IDs are not passed into the TYPE_BYTES field. It also adds a pre-pass to correctly resolve function names from tool call IDs for tool responses.
- Ensure ALL assistant messages in history have reasoning_content and string content.
- Use a single space as a professional minimal placeholder for missing reasoning.
- Log full offending request bodies at ERROR level for detailed debugging.
- Fix DeepSeek R1 (reasoner) 400 errors by ensuring assistant messages with
tool_calls in history always have non-null 'content' and 'reasoning_content'.
- Implement deterministic tool call ID truncation (max 40 chars) for OpenAI
compatibility (fixes errors when history contains long Gemini signatures).
- Automatic transition from 'max_tokens' to 'max_completion_tokens' for newer
OpenAI models (o1, o3, gpt-5-nano).
- Added 'reasoning' and 'thought' aliases to reasoning_content for robust
deserialization from various clients.
Newer OpenAI models (o1, o3, gpt-5) have deprecated 'max_tokens' in favor of
'max_completion_tokens'. The provider now automatically maps this parameter
to ensure compatibility and avoid 400 errors.
OpenAI has a strict 40-character limit for tool call IDs. Long IDs (like
Gemini's 56-char thought signatures) are now deterministically truncated
to 40 characters when sending history back to OpenAI-compatible providers.
- Move DeepSeek R1 reasoning_content and content:"" fixes to DeepSeekProvider only.
- Restore OpenAI-standard null content for tool calls in helpers.rs.
- Fixes 400 Bad Request for gpt-5-nano and other strict OpenAI models.
- Ensure assistant tool calls always have content: "" instead of null.
- Add debug-level logging of the full request body when DeepSeek returns 400.
- Improved R1 placeholder injection to include content sanitation.
- Added aliases 'reasoning' and 'thought' to reasoning_content field for better client compatibility.
- Implemented automatic 'Thinking...' placeholder injection for deepseek-reasoner history messages that contain tool_calls but lack reasoning_content.
- Restored strict parameter sanitation for deepseek-reasoner.
- Introduce AuthInfo struct for shared auth state.
- Populate AuthInfo in rate_limit_middleware and store in request extensions.
- Update AuthenticatedClient extractor to use pre-resolved AuthInfo.
- Simplify chat_completions by removing redundant DB lookups.
Gemini often sends tool calls in one chunk and then 'STOP' in a final chunk.
If we pass the raw 'stop' at the end, clients stop and ignore the previously
received tool calls. We now track if any tools were seen and override the
final 'stop' to 'tool_calls'.
Gemini often reports 'STOP' even when tool calls are generated. To remain
OpenAI-compatible and ensure clients execute tools and continue, we must
report 'tool_calls' as the finish_reason when tools are present.
- Remove from as it is rejected by the API inside .
- Ensure is always a JSON object (google.protobuf.Struct), wrapping non-object tool results in .
- Update extraction logic to only look for in sibling fields.
- Ensure is preserved in conversation history for Gemini 3 models.
- Support multiple naming conventions (snake_case and camelCase).
- Implement stable tool call ID tracking during streaming using a stateful map.
- Improve extraction from both Gemini parts and function calls.
- Fix incorrect tool call indices during streaming.
- The native Gemini REST API requires camelCase 'thoughtSignature' as a sibling to functionCall.
- Explicitly rename the field to match this requirement, resolving the 'missing thought_signature' 400 error.
- Only restore thought_signature if the tool call ID doesn't start with 'call_'.
- This ensures proxy-generated UUIDs are never sent back to Gemini as signatures, which was causing base64 decoding failures.
- Extract thought_signature from the Part level during response parsing.
- Provide thought_signature as a sibling to functionCall during request assembly.
- This fully resolves the 'Unknown name thoughtSignature at function_call' error.
- Update get_base_url to only perform replacement if the base_url specifically ends with /v1.
- This prevents malformed URLs like /v1betabeta when the base_url was already configured as v1beta.
- Switch Gemini 3 models to v1beta for both streaming and non-streaming (better reasoning support).
- Increase max_output_tokens cap to 65536 for reasoning-heavy models.
- Elevate API URL and chunk tracing to INFO level for easier production debugging.
