- Check if store has keyPath before calling put()
- If keyPath exists (in-line keys), only pass value: store.put(value)
- If no keyPath (out-of-line keys), pass both: store.put(value, key)
- Apply fix to both set() and transaction.set()
- Fixes DataError when saving sessions with keyPath: 'id'
- Create base Store class with private backend and protected getBackend()
- Add SettingsStore, ProviderKeysStore, SessionsStore
- Each store defines its own schema via getConfig()
- AppStorage now takes stores + backend in constructor
- Remove SessionsRepository (logic moved to SessionsStore)
- Update all consumers to use store API (storage.settings.get/set, storage.providerKeys.get/set)
- Update example app to follow new pattern: create stores, gather configs, create backend, wire
- Benefits: stores own their schema, no circular deps, cleaner separation
- Replace fragmented storage backends with single IndexedDBStorageBackend
- Create multi-store StorageBackend interface (storeName parameter)
- Remove old backends: IndexedDBBackend, LocalStorageBackend, SessionIndexedDBBackend, WebExtensionStorageBackend
- Remove old repositories: ProviderKeysRepository, SessionRepository, SettingsRepository
- Simplify AppStorage to directly expose storage methods (getSetting/setSetting, getProviderKey/setProviderKey)
- Create SessionsRepository for session-specific operations
- Update all consumers to use new simplified API
- Update example app to use new storage architecture
- Benefits: 10GB+ quota (vs 10MB chrome.storage), single database, consistent API
- Update renderHeader and renderCollapsibleHeader in renderer-registry.ts to accept `text: string | TemplateResult`
- Remove duplicated renderCollapsibleHeaderWithPill helper in artifacts-tool-renderer.ts
- Update all artifact renderer calls to use renderHeaderWithPill() inline
- Remove all separate pill rendering below headers
This allows artifact pills to be rendered inline with header text without code duplication.
- Create ArtifactPill component (similar to SkillPill)
- Renders filename as clickable pill with FileCode2 icon
- Clicking pill opens artifacts panel and selects that artifact
- Update ArtifactsToolRenderer to accept artifactsPanel reference
- Pass artifactsPanel from ChatPanel to renderer on initialization
- Display artifact pill below header for all commands
- Pill only clickable when artifactsPanel reference is available
- All actions except DELETE now use collapsible headers
- CREATE/UPDATE/REWRITE/GET/LOGS: code/output collapsed by default
- DELETE: keeps simple non-collapsible header
- Fix isStreaming parameter usage for proper spinner state
- Add smooth 300ms animation on expand/collapse
- Full header is clickable to toggle collapse state
- Add renderCollapsibleHeader() to renderer-registry
- Places chevron on right, spinner on left
- Toggles between ChevronRight (collapsed) and ChevronDown (expanded)
- Uses max-h-0/max-h-[2000px] with transition-all for smooth animation
- Dynamically adds/removes mt-3 to avoid margin when collapsed
- Update javascript-repl renderer to use collapsible sections
- Code and console output hidden by default
- Only file attachments remain visible
- 300ms smooth animation on expand/collapse
- Export renderCollapsibleHeader from web-ui index
- Extract ArtifactsToolRenderer from ArtifactsPanel into standalone renderer
- Fix ChatPanel to register ArtifactsToolRenderer instead of panel

- Export both names for backward compatibility
- Fix tsc --preserveWatchOutput in web-ui dev script to prevent console clearing
This fixes the "browser is not defined" error in Chrome extensions.
- Move mini-lit from dependencies to peerDependencies

- Fixes "Could not establish connection" errors when sidepanel URL updates
- Remove unused currentTabUrl/currentTabIndex tracking variables
ChatPanel layout fixes:
- Fix windowWidth initialization (was 0 due to too-early evaluation)
- Set windowWidth in connectedCallback after DOM connection
- Add requestAnimationFrame to ensure width is measured after layout
- Add debug logging for troubleshooting layout issues
- Now properly respects BREAKPOINT (800px) for mobile vs desktop layout
- Remove complex agent busy state tracking
- Remove checkAndInsertNavMessage helper and onBeforeSend logic
- Directly insert navigation messages when tab URL changes (chrome.tabs.onUpdated)
- Also insert when user switches to a different tab (chrome.tabs.onActivated)
- Much simpler: every URL change = navigation message, no conditions
- Fixes issue where browser_javascript navigation wasn't detected
- Track agent busy state: isStreaming OR pendingToolCalls.size > 0
- When agent transitions from busy to idle, check for URL changes
- Extract checkAndInsertNavMessage() helper function
- Call helper from both onBeforeSend (user submit) and agent state subscription (post-tool)
- Fixes issue where browser_javascript tool navigates page but no nav message inserted
- Navigation messages now appear after tools that change window.location.href
- Remove automatic navigation message insertion from tab change listeners
- Tab listeners now only track current tab state (currentTabUrl, currentTabIndex)
- Navigation messages are only inserted via onBeforeSend callback when user submits
- Prevents spam of navigation messages when user is just browsing without interacting with agent
- Add fallback favicon using Google's favicon service (s2/favicons API)
- If both tab.favIconUrl and Google service fail, gracefully hide broken image
- Enhance navigation message styling for better visibility:
- Use accent colors (bg-accent/50 with border-accent) instead of muted secondary
- Increase padding (px-3 py-2) and add vertical margin (my-2)
- Add shadow-sm for subtle depth
- Make title font-medium for better contrast
- Use border-2 instead of border for more prominence

- Comment out PersistentStorageDialog in both web-ui example and browser extension (TODO: fix)
- Add Known Bugs section to both README.md files documenting PersistentStorageDialog issue
- Clean up navigation tracking variable names in browser extension
- Add ?new=true query param to prevent auto-loading latest session
- Style navigation message as clickable badge with background
- Add cursor-pointer, truncate, and max-width for proper text overflow
- Click navigation message to open page in new tab
- Show URL on hover
- Add onBeforeSend callback to ChatPanel and AgentInterface

- Create NavigationMessage custom message type
- Add browserMessageTransformer that converts nav messages to <system> tags

Major architectural improvements:
- Renamed AgentSession → Agent (state/ → agent/)
- Removed id field from AgentState
- Fixed transport abstraction to pass messages directly instead of using callbacks
- Eliminated circular dependencies in transport creation
Transport changes:

- Persistent storage permission dialog
- Browser extension now auto-loads last session
UI improvements:

- Added "Drop files here" i18n strings
- Changed "Continue Without Saving" → "Continue Anyway"
Web example:

- Rename showThinking → showThinkingSelector in AgentInterface and ChatPanel for consistency
- Remove showDebugToggle property from AgentInterface (unused)
- Clean up browser-javascript tool output message (remove CSP note)
Storage Architecture:
- New pluggable storage system with backends (LocalStorage, ChromeStorage, IndexedDB)
- SettingsRepository for app settings (proxy config, etc.)
- ProviderKeysRepository for API key management
- AppStorage with global accessors (getAppStorage, setAppStorage, initAppStorage)
Transport Refactoring:
- Renamed DirectTransport → ProviderTransport (calls LLM providers with optional CORS proxy)
- Renamed ProxyTransport → AppTransport (uses app server with user auth)
- Updated TransportMode: "direct" → "provider", "proxy" → "app"
CORS Proxy Integration:
- ProviderTransport checks proxy.enabled/proxy.url from storage
- When enabled, modifies model baseUrl to route through proxy: {proxyUrl}/?url={originalBaseUrl}
- ProviderKeyInput test function also honors proxy settings
- Settings dialog with Proxy tab (Switch toggle, URL input, explanatory description)
Anthropic Prompt Caching:
- System prompt cached with cache_control markers (both OAuth and regular API keys)
- Last user message cached to cache conversation history
- Saves 90% on input tokens for cached content (10x cost reduction)
Settings Dialog Improvements:
- Configurable tab system with SettingsTab base class
- ApiKeysTab and ProxyTab as custom elements
- Switch toggle for proxy enable (instead of Checkbox)
- Explanatory paragraphs for each tab
