* docs: add cross-domain troubleshooting to offline deployment guide
* make it simple
* Remove common issues section from offline deployment docs
Removed common issues section regarding cross-domain configuration and rebuilding after configuration changes.
* feat: add toggle to show unvalidated models in model selector
Add a toggle switch in the model configuration dialog to allow users to
display models that haven't been validated. This helps users who work with
model providers that have disabled their verification endpoints.
Changes:
- Add showUnvalidatedModels field to MultiModelConfig type
- Add setShowUnvalidatedModels method to useModelConfig hook
- Add Switch toggle in model-config-dialog footer
- Update model-selector to filter based on showUnvalidatedModels setting
- Add warning icon for unvalidated models in the selector
- Add i18n translations for en/zh/ja

* fix: wrap AlertTriangle in span for title attribute
The AlertTriangle icon from lucide-react doesn't support the title prop directly.
Wrapped it in a span element to properly display the tooltip.

- Use fixed port 61337 in production instead of random ports (10000-65535)
- localStorage is origin-specific, so random ports caused settings loss
- Add locale save/restore since language is URL-based
- Fixes#399
- Button now shows 'Test' by default instead of persisting 'Verified' state
- Verified status is still shown via green badge in provider header
- Updated OpenAI suggested models list with latest GPT-5.x series
- Add warning banner to settings window HTML
- Add CSS styling for deprecation notice (light/dark mode)
- Direct users to use AI Model Configuration button in chat panel
Fixes#374 - Models were confused by the `type` field name and sent
`operation` instead. This change:
- Renames DiagramOperation.type to DiagramOperation.operation across
all files (MCP server, web app, hooks, components, system prompts)
- Adds JSON examples in tool descriptions to show correct format
- Updates all test data to use the new field name
Affected files:
- lib/utils.ts
- app/api/chat/route.ts
- hooks/use-diagram-tool-handlers.ts
- components/chat-message-display.tsx
- lib/system-prompts.ts
- packages/mcp-server/src/diagram-operations.ts
- packages/mcp-server/src/index.ts
- scripts/test-diagram-operations.mjs
MCP server version bumped to 0.1.6
* fix: use full IP for userId to prevent quota collision
- Remove .slice(0, 8) from base64 encoded IP
- Each IP now has unique userId (no /16 collision)
- Affects: quota tracking, Langfuse tracing
* refactor: extract getUserIdFromRequest to shared utility
- Create lib/user-id.ts with shared function
- Fix misleading 'privacy' comment (base64 is not privacy)
- Remove duplicate code from chat and log-feedback routes
Switch from blocklist to whitelist approach - only export spans named
'chat' or starting with 'ai.' to filter out Next.js infrastructure noise
(HEAD, fetch, POST requests).
- Fixed bug where daily quota counts weren't resetting on new day
(if_not_exists only works for missing attributes, not day changes)
- Changed to two-phase approach: reset if new day, then increment
- Added QUOTA_TIMEZONE env var for local midnight reset (e.g., Asia/Tokyo)
- Added timezone validation with UTC fallback
- Move DEV_XML_PRESETS constants to new file
- Create DevXmlSimulator component with all simulator logic
- Add preset dropdown with 5 test cases including HTML escape test
- Set default interval to 1ms and chunk size to 10 chars
- Simplify chat-panel.tsx by removing ~130 lines of inline code
- Add HTML escaping (<, >) in convertToLegalXml for attribute values
- Update isMxCellXmlComplete to handle any LLM provider's wrapper tags
- Add wrapper tag stripping in wrapWithMxFile for DeepSeek/Anthropic tags
- Update autoFixXml to escape both < and > in attribute values
Fixes 'Malformed XML detected in final output' error when AI generates
diagrams with HTML content in value attributes like <b>Title</b>.
- Add CSS design system tokens (surfaces, borders, animations) to globals.css
- Update dialog.tsx with rounded-2xl, shadow-dialog, refined close button
- Enhance input.tsx with rounded-xl and refined focus states
- Refactor settings-dialog with SettingItem pattern and consistent control sizing
- Refactor model-config-dialog with ConfigSection/ConfigCard helpers
- Replace emerald-* classes with success design tokens
- Remove unused ValidationButton component and scrollState
- Parse JSON error response from server to get actual used/limit values
- Previously showed 0/0 due to race condition (config fetch vs error)
- AI SDK puts full response body in error.message for non-OK responses
- Updated all quota toasts (request, token, TPM) to use server values
Third-party OpenAI-compatible proxies typically don't support the
/responses endpoint. Use .chat() for custom baseURLs while keeping
Responses API for official OpenAI to preserve reasoning model support.
Fixes#377
- Add extractCompleteMxCells() to extract only complete mxCell elements from partial XML
- Remove useEffect cleanup that was killing debounce timeouts on every re-render
- Wrap XML in <root> tags for proper DOMParser validation
Previously, diagrams only rendered after ALL XML finished streaming because:
1. useEffect cleanup cleared the 150ms debounce timeout on every message change
2. DOMParser rejected partial XML like '<mxCell id="2" value="...' (incomplete)
Now each complete mxCell renders progressively as it finishes streaming.
- Add dynamo-quota-manager.ts for atomic quota checks using ConditionExpression
- Enforce daily request limit, daily token limit, and TPM limit
- Return 429 with quota details (type, used, limit) when exceeded
- Quota is opt-in: only enabled when DYNAMODB_QUOTA_TABLE env var is set
- Remove client-side quota enforcement (server is now source of truth)
- Simplify use-quota-manager.tsx to only display toasts
- Add @aws-sdk/client-dynamodb dependency
Previously, continuation mode (for truncated XML) had unlimited client-side
retries, relying only on server stepCountIs(5) limit. This could cause
excessive API calls (495 observed) when XML truncation kept occurring.
Added MAX_CONTINUATION_RETRY_COUNT=2 to limit continuation attempts:
- After 2 failed continuation attempts, shows error toast and stops
- Resets on successful completion or user-initiated message
- Also resets when quota limits are hit
In multi-step tool flows, messages array contains assistant messages
from previous steps. Using messages[messages.length - 1] would record
the assistant's response as trace input instead of the user's question.
- Use Responses API instead of Chat Completions API for OpenAI
(.chat() -> default call) to support reasoning events
- Add o4 to reasoning model detection
- Change default reasoningSummary from 'detailed' to 'auto'
(not all models support 'detailed')
- Update types to match AI SDK: 'auto' | 'detailed'
- Upgrade ai package from ^5.0.89 to ^6.0.1
- Upgrade @ai-sdk/* provider packages to latest v3/v4
- Update convertToModelMessages call to async (new API)
- Fix usage.cachedInputTokens to usage.inputTokenDetails?.cacheReadTokens
- Add ~40 new translation keys for model-config-dialog and model-selector
- Support English, Chinese, and Japanese translations
- Replace all hardcoded strings with dictionary lookups
