- Router was stopping propagation after first handler returned true
- This prevented consumers from seeing messages that providers handled
- executionConsumer never received execution-complete because ConsoleRuntimeProvider handled it first
- Now all providers and consumers receive all messages
- Fixes javascript_repl never completing
- ConsoleRuntimeProvider was handling execution-complete and returning true
- This stopped message propagation before executionConsumer could handle it
- ExecutionConsumer never got execution-complete, so promise never resolved
- Now ConsoleRuntimeProvider responds but returns false to allow propagation
- Fixes javascript_repl never completing (30s timeout)
- window.complete() was fire-and-forget, causing execution-complete to arrive before console messages
- This caused sandbox to unregister before console message responses arrived
- Made complete() async and await sendRuntimeMessage()
- SandboxedIframe wrapper now awaits window.complete()
- Ensures all messages are processed before cleanup/unregister
- Fixes 30-second timeout on javascript_repl
- ConsoleRuntimeProvider.handleMessage() was not calling respond()
- This caused sendRuntimeMessage() to hang waiting for response (30s timeout)
- Now properly acknowledges console, execution-complete, and execution-error messages
- Fixes javascript_repl hanging on simple console.log() calls
- Remove fallback timeout from ConsoleRuntimeProvider (was causing 2s delays)
- Add completion callback support to SandboxedIframe REPL wrapper
- Call completion callbacks before window.complete() in both success/error paths
- Both browser-javascript and javascript-repl now use identical completion pattern
- Ensures console logs are batched and sent before execution completes
Major refactoring to unify runtime providers across sandbox and user script contexts:
1. Runtime Bridge & Router
- Add RuntimeMessageBridge for unified messaging abstraction
- Rename SandboxMessageRouter → RuntimeMessageRouter
- Router now handles both iframe and user script messages
- Guard for non-extension environments
2. Provider Refactoring
- ArtifactsRuntimeProvider: Add offline mode with snapshot fallback
- AttachmentsRuntimeProvider: Remove returnDownloadableFile (moved to dedicated provider)
- ConsoleRuntimeProvider: Add message collection, remove lifecycle logic
- FileDownloadRuntimeProvider: New provider for file downloads
3. HTML Escaping Fix
- Escape </script> in JSON.stringify output to prevent premature tag closure
- Applies when injecting provider data into <script> tags
- JavaScript engine automatically unescapes, no runtime changes needed
4. Function Renaming
- listFiles → listAttachments
- readTextFile → readTextAttachment
- readBinaryFile → readBinaryAttachment
- returnFile → returnDownloadableFile
5. Updated Exports
- Export new RuntimeMessageBridge and RuntimeMessageRouter
- Export FileDownloadRuntimeProvider
- Update all cross-references
This sets the foundation for reusing providers in browser-javascript tool.
- 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

- 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

- 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

- 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

- Update to use globalThis.browser || globalThis.chrome for Firefox/Chrome compatibility
- 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.

- 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
