Add the ability to reset a project to its initial state with two options:
- Quick Reset: Clears features.db, assistant.db, and settings files while
preserving app spec and prompts
- Full Reset: Deletes everything including prompts directory, triggering
the setup wizard for project reconfiguration
Backend changes:
- Add POST /{name}/reset endpoint to projects router with full_reset query param
- Validate agent lock file to prevent reset while agent is running (409 Conflict)
- Dispose database engines before deleting files to release Windows file locks
- Add engine caching to api/database.py for better connection management
- Add dispose_engine() functions to both database modules
- Delete WAL mode journal files (*.db-wal, *.db-shm) during reset
Frontend changes:
- Add ResetProjectModal component with toggle between Quick/Full reset modes
- Add ProjectSetupRequired component shown when has_spec is false
- Add resetProject API function and useResetProject React Query hook
- Integrate reset button in header (disabled when agent running)
- Add 'R' keyboard shortcut to open reset modal
- Show ProjectSetupRequired when project needs setup after full reset
This implements the feature from PR #4 directly on master to avoid merge
conflicts.

- Create shared `isSubmitEnter()` utility in `ui/src/lib/keyboard.ts`
for IME-aware Enter key handling across all input components
- Extract magic number 48 to named constant `COLLAPSED_DEBUG_PANEL_CLEARANCE`
with explanatory comment (40px panel header + 8px margin)
- Update 5 components to use the new utility:
- AssistantChat.tsx
- ExpandProjectChat.tsx
- SpecCreationChat.tsx
- FolderBrowser.tsx
- TerminalTabs.tsx
This follows up on PR #121 which added IME composition checks. The
refactoring centralizes the logic for easier maintenance and documents
the padding value that prevents Kanban cards from being cut off when
the debug panel is collapsed.

Change CSS import from bare module specifier to url() syntax to fix
Vite/Tailwind CSS resolution issues on some systems.
- Changed `@import "tw-animate-css"` to `@import url("tw-animate-css")`
- The url() wrapper ensures proper package resolution across platforms
- Fixes "Can't resolve 'tw-animate-css'" build error
The bare import syntax failed because Vite's CSS processing didn't
properly resolve the package exports. Using url() bypasses this issue
while still correctly resolving the npm package from node_modules.

(AssistantPanel slide animation, DebugLogViewer resize handle)
- Add browser validation to get_playwright_browser() with warning for
invalid values (matches get_playwright_headless() behavior)
- Remove phantom SQLite documentation from CUSTOM_UPDATES.md that
described features not present in PR #93
- Update checklist and revert instructions to match actual changes

- Check for 'not found' message (server response) in addition to '404'
- Only clear stored conversation ID on actual 404 errors
- Prevent unnecessary retries for deleted conversations
- Don't clear conversation on transient network errors
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
When a stored conversation ID no longer exists (e.g., database was reset
or conversation was deleted), the UI would repeatedly try to fetch it,
causing endless 404 errors in the console.
This fix:
- Stops retrying on 404 errors (conversation doesn't exist)
- Automatically clears the stored conversation ID from localStorage
when a 404 is received, allowing the user to start fresh

Create custom-theme.css for theme overrides that won't conflict
with upstream updates. The file loads after globals.css, so its
CSS variables take precedence.
This approach ensures:
- Zero merge conflicts on git pull (new file, not in upstream)
- Theme persists across upstream updates
- Easy to modify without touching upstream code

Previously, agents that completed their work would remain visible in the
Mission Control UI until a manual page refresh. This occurred because
the AgentTracker._handle_agent_complete method silently dropped completion
messages when an agent wasn't tracked (e.g., due to missed start messages
from WebSocket connection issues).
Backend changes:
- Modified _handle_agent_complete in server/websocket.py to always emit
completion messages, even for untracked agents
- Synthetic completions use agentIndex=-1 and agentName='Unknown' as
sentinel values to indicate untracked agents
Frontend changes:
- Updated useWebSocket.ts to handle synthetic completions by removing
agents by featureId when agentIndex is -1
- Added 30-minute stale agent cleanup as defense-in-depth for users who
leave the UI open for extended periods
- Updated TypeScript types to allow 'Unknown' as valid agent name
Component updates:
- AgentAvatar.tsx: Added UNKNOWN_COLORS and UnknownSVG fallback for
rendering unknown agents with a neutral gray question mark icon
- CelebrationOverlay.tsx, DependencyGraph.tsx: Updated interfaces to
accept 'Unknown' agent names

Add real-time visibility into the parallel orchestrator's decisions
and state in the Mission Control UI. The orchestrator now has its
own avatar ("Maestro") and displays capacity/queue information.
Backend changes (server/websocket.py):
- Add OrchestratorTracker class that parses orchestrator stdout
- Define regex patterns for key orchestrator events (spawn, complete, capacity)
- Track coding/testing agent counts, ready queue, blocked features
- Emit orchestrator_update WebSocket messages
- Reset tracker state when agent stops or crashes
Frontend changes:
- Add OrchestratorState, OrchestratorStatus, OrchestratorEvent types
- Add WSOrchestratorUpdateMessage to WSMessage union
- Handle orchestrator_update in useWebSocket hook
- Create OrchestratorAvatar component (Maestro - robot conductor)
- Create OrchestratorStatusCard with capacity badges and event ticker
- Update AgentMissionControl to show orchestrator above agent cards
- Add conducting/baton-tap CSS animations for Maestro
The orchestrator status card shows:
- Maestro avatar with state-based animations
- Current orchestrator state and message
- Coding agents, testing agents, ready queue badges
- Blocked features count (when > 0)
- Collapsible recent events list

Major refactoring of the parallel orchestrator to run regression testing
agents independently from coding agents. This improves system reliability
and provides better control over testing behavior.
Key changes:
Database & MCP Layer:
- Add testing_in_progress and last_tested_at columns to Feature model
- Add feature_claim_for_testing() for atomic test claim with retry
- Add feature_release_testing() to release claims after testing
- Refactor claim functions to iterative loops (no recursion)
- Add OperationalError retry handling for transient DB errors
- Reduce MAX_CLAIM_RETRIES from 10 to 5
Orchestrator:
- Decouple testing agent lifecycle from coding agents
- Add _maintain_testing_agents() for continuous testing maintenance
- Fix TOCTOU race in _spawn_testing_agent() - hold lock during spawn
- Add _cleanup_stale_testing_locks() with 30-min timeout
- Fix log ordering - start_session() before stale flag cleanup
- Add stale testing_in_progress cleanup on startup
Dead Code Removal:
- Remove count_testing_in_concurrency from entire stack (12+ files)
- Remove ineffective with_for_update() from features router
API & UI:
- Pass testing_agent_ratio via CLI to orchestrator
- Update testing prompt template to use new claim/release tools
- Rename UI label to "Regression Agents" with clearer description
- Add process_utils.py for cross-platform process tree management
Testing agents now:
- Run continuously as long as passing features exist
- Can re-test features multiple times to catch regressions
- Are controlled by fixed count (0-3) via testing_agent_ratio setting
- Have atomic claiming to prevent concurrent testing of same feature

Changes:
- Revert incorrect import from claude_code_sdk to claude_agent_sdk in agent.py
(PR #50 introduced an undocumented change to a deprecated package)
- Clear activeAgents and recentActivity in useWebSocket when agent stops
to prevent stale UI state
The claude_code_sdk package is deprecated (last updated Sep 2025) while
claude_agent_sdk is the active, maintained package. The import change in
PR #50 was undocumented and would have caused ImportError since only
claude-agent-sdk is specified in requirements.txt.

Performance improvements:
- Fix N+1 query in get_conversations() using COUNT subquery instead of
len(c.messages) which triggered lazy loading for each conversation
- Add SQLAlchemy engine caching to avoid creating new database connections
on every request
- Add React.memo to ChatMessage component to prevent unnecessary re-renders
during message streaming
- Move BOLD_REGEX to module scope to avoid recreating on each render
Code quality improvements:
- Remove 10+ console.log debug statements from AssistantChat.tsx and
AssistantPanel.tsx that were left from development
- Add user feedback for delete errors in ConversationHistory - dialog now
stays open and shows error message instead of silently failing
- Update ConfirmDialog to accept ReactNode for message prop to support
rich error content
These changes address issues identified in the code review of PR #74
(conversation history feature).

- Update ScheduleModal to correctly adjust days_of_week when crossing
day boundaries during UTC conversion (fixes schedules running on
wrong days for users in extreme timezones like UTC+9)
Backend Fixes:
- Add MAX_SCHEDULES_PER_PROJECT (50) limit to prevent resource exhaustion
- Wire up crash recovery callback in scheduler_service._start_agent()
- Convert schedules.py endpoints to use context manager for DB sessions

Security fixes to restore defense-in-depth after merging PR #78:
**client.py:**
- Revert permission mode from "bypassPermissions" to "acceptEdits"
- Remove redundant web_tools_auto_approve_hook from PreToolUse hooks
- Remove unused import of web_tools_auto_approve_hook
**security.py:**
- Remove web_tools_auto_approve_hook function (was redundant and
returned {} for ALL tools, not just WebFetch/WebSearch)
**server/services/spec_chat_session.py:**
- Restore allowed_tools restriction: [Read, Write, Edit, Glob,
WebFetch, WebSearch]
- Revert permission mode from "bypassPermissions" to "acceptEdits"
- Keeps setting_sources=["project", "user"] for global skills access
**ui/src/components/AgentAvatar.tsx:**
- Remove unused getMascotName export to fix React Fast Refresh warning
- File now only exports AgentAvatar component as expected
The bypassPermissions mode combined with unrestricted tool access in
spec_chat_session.py created a security gap where Bash commands could
execute without validation (sandbox disabled, no bash_security_hook).

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Memoize onNodeClick callback in App.tsx to prevent unnecessary re-renders
- Add useRef pattern in DependencyGraph to store callback without triggering
useMemo recalculation when callback identity changes
- Add hash-based change detection to only update ReactFlow state when
actual graph data changes (node status, edges), not on every parent render
- Add GraphErrorBoundary class component to catch ReactFlow rendering errors
and provide a "Reload Graph" recovery button instead of blank screen
- Wrap DependencyGraph with error boundary and resetKey for graceful recovery
The root cause was frequent WebSocket updates during active agent sessions
causing parent re-renders, which created new inline callback functions,
triggering useMemo/useEffect chains that corrupted ReactFlow's internal state
over time (approximately 1 minute of continuous updates).
