fix: enhance execution phase handling in ProjectStore

- Added logic to correct stale execution phases when a task reaches a terminal status (human_review, done, pr_created) but the persisted executionPhase is outdated. - Improved the determination of execution progress to ensure accurate representation of task status, particularly for tasks that have transitioned from running to completed states. These changes improve the reliability of task status updates and enhance user experience by ensuring accurate visual feedback on task execution phases.

-# PR Review System Robustness
-
-## What This Is
-
-Improvements to Auto Claude's PR review system to make it trustworthy enough to replace human review. The system uses specialist agents (security, logic, quality, codebase-fit) with a finding-validator that re-investigates findings before presenting them. This milestone fixes gaps that cause false positives and missed context.
-
-## Core Value
-
-**When the system flags something, it's a real issue.** Trustworthy PR reviews that are faster, more thorough, and more accurate than human review.
-
-## Requirements
-
-### Validated
-
- ✓ Multi-agent PR review architecture — existing
- ✓ Specialist agents (security, logic, quality, codebase-fit) — existing
- ✓ Finding-validator for follow-up reviews — existing
- ✓ Dismissal tracking with reasons — existing
- ✓ CI status enforcement — existing
- ✓ Context gathering (diff, comments, related files) — existing
-
-### Active
-
- [ ] **REQ-001**: Finding-validator runs on initial reviews (not just follow-ups)
- [ ] **REQ-002**: Fix line 1288 bug — include ai_reviews in follow-up context
- [ ] **REQ-003**: Fetch formal PR reviews from `/pulls/{pr}/reviews` API
- [ ] **REQ-004**: Add Read/Grep/Glob tool instructions to all specialist prompts
- [ ] **REQ-005**: Expand JS/TS import analysis (path aliases, CommonJS, re-exports)
- [ ] **REQ-006**: Add Python import analysis (currently skipped)
- [ ] **REQ-007**: Increase related files limit from 20 to 50 with prioritization
- [ ] **REQ-008**: Add reverse dependency analysis (what imports changed files)
-
-### Out of Scope
-
- Real-time review streaming — complexity, not needed for accuracy goal
- Review caching/memoization — premature optimization
- Custom specialist agents — current four dimensions sufficient
-
-## Context
-
-**Problem**: False positives in PR reviews erode trust. Users have to second-guess every finding, defeating the purpose of automated review.
-
-**Root cause**: Finding-validator (which catches false positives) only runs during follow-up reviews. Initial reviews present unvalidated findings. Additionally, context gathering has bugs and gaps that cause the AI to make claims without complete information.
-
-**Existing system**:
- `apps/backend/runners/github/` — PR review orchestration
- `apps/backend/runners/github/services/parallel_orchestrator_reviewer.py` — initial review
- `apps/backend/runners/github/services/parallel_followup_reviewer.py` — follow-up review (has finding-validator)
- `apps/backend/runners/github/context_gatherer.py` — gathers PR context
- `apps/backend/prompts/github/pr_*.md` — specialist agent prompts
-
-**Reference**: Full PRD at `docs/PR_REVIEW_SYSTEM_IMPROVEMENTS.md`
-
-## Constraints
-
- **Existing architecture**: Work within current multi-agent PR review structure
- **Backward compatibility**: Don't break existing review workflows
- **Performance**: Validation step should not significantly slow reviews (run in parallel where possible)
-
-## Key Decisions
-
-| Decision | Rationale | Outcome |
-|----------|-----------|---------|

-# Architecture
-
-**Analysis Date:** 2026-01-19
-
-## Pattern Overview
-
-**Overall:** Multi-Agent Orchestration with Electron Desktop UI
-
-**Key Characteristics:**
- Dual-app architecture: Python backend (CLI + agents) + Electron frontend (desktop UI)
- Agent-based autonomous coding via Claude Agent SDK
- Git worktree isolation for safe parallel development
- Phase-based pipeline execution for spec creation and implementation
- Event-driven IPC communication between frontend and backend
-
-## Layers
-
-**Frontend (Electron Main Process):**
- Purpose: Desktop application shell, native OS integration, IPC coordination
- Location: `apps/frontend/src/main/`
- Contains: Window management, IPC handlers, service managers (terminal, python env, CLI tools)
- Depends on: Backend Python CLI, Claude Code CLI
- Used by: Renderer process via IPC
-
-**Frontend (Renderer Process):**
- Purpose: React-based user interface
- Location: `apps/frontend/src/renderer/`
- Contains: Components, Zustand stores, hooks, contexts
- Depends on: Main process via preload IPC bridge
- Used by: End users
-
-**Backend Core:**
- Purpose: Authentication, SDK client factory, security, workspace management
- Location: `apps/backend/core/`
- Contains: `client.py` (SDK factory), `auth.py`, `worktree.py`, `workspace.py`, security hooks
- Depends on: Claude Agent SDK, project analyzer
- Used by: Agents, CLI commands, runners
-
-**Backend Agents:**
- Purpose: AI agent implementations for autonomous coding
- Location: `apps/backend/agents/`
- Contains: Coder, planner, memory manager, session management
- Depends on: Core client, prompts, phase config
- Used by: CLI commands, QA loop
-
-**Backend QA:**
- Purpose: Quality assurance validation loop
- Location: `apps/backend/qa/`
- Contains: QA reviewer, QA fixer, criteria validation, issue tracking
- Depends on: Agents, core client
- Used by: CLI commands after build completion
-
-**Backend Spec:**
- Purpose: Spec creation pipeline with complexity-based phases
- Location: `apps/backend/spec/`
- Contains: Pipeline orchestrator, complexity assessment, validation
- Depends on: Core client, agents
- Used by: CLI spec commands, frontend task creation
-
-**Backend Security:**
- Purpose: Command validation, allowlist management, secrets scanning
- Location: `apps/backend/security/`
- Contains: Validators, hooks, command parser, secrets scanner
- Depends on: Project analyzer
- Used by: Core client via pre-tool-use hooks
-
-**Backend CLI:**
- Purpose: Command-line interface and argument routing
- Location: `apps/backend/cli/`
- Contains: Main entry, build/spec/workspace/QA commands
- Depends on: All backend modules
- Used by: Entry point (`run.py`), frontend terminal
-
-## Data Flow
-
-**Spec Creation Flow:**
-1. User creates task via frontend or CLI (`--task "description"`)
-2. `SpecOrchestrator` (`spec/pipeline/orchestrator.py`) initializes
-3. Complexity assessment determines phase count (3-8 phases)
-4. `AgentRunner` executes phases: Discovery -> Requirements -> [Research] -> Context -> Spec -> Plan -> Validate
-5. Each phase uses Claude Agent SDK session with phase-specific prompts
-6. Output: `spec.md`, `requirements.json`, `context.json`, `implementation_plan.json`
-
-**Implementation Flow:**
-1. CLI starts with `python run.py --spec 001`
-2. `run_autonomous_agent()` in `agents/coder.py` orchestrates
-3. Planner agent creates subtask-based `implementation_plan.json`
-4. Coder agent implements subtasks in iteration loop
-5. Each subtask runs as Claude Agent SDK session
-6. On completion, QA validation loop runs (`qa/loop.py`)
-7. QA reviewer validates -> QA fixer fixes issues -> loop until approved
-
-**Frontend-Backend IPC Flow:**
-1. Renderer component dispatches action (e.g., start task)
-2. Zustand store calls `window.api.invoke('ipc-channel', args)`
-3. Preload script bridges to main process
-4. IPC handler in `ipc-handlers/` processes request
-5. Handler spawns Python subprocess or manages terminal
-6. Events streamed back via IPC to update stores
-
-**State Management:**
- Frontend: Zustand stores per domain (`task-store`, `project-store`, `settings-store`, etc.)
- Backend: File-based state (`implementation_plan.json`, `qa_report.md`)
- Session recovery: `RecoveryManager` tracks agent sessions for resumption
-
-## Key Abstractions
-
-**ClaudeSDKClient:**
- Purpose: Configured Claude Agent SDK client with security hooks
- Examples: `apps/backend/core/client.py:create_client()`
- Pattern: Factory function with multi-layered security (sandbox, permissions, hooks)
-
-**SpecOrchestrator:**
- Purpose: Coordinates spec creation pipeline phases
- Examples: `apps/backend/spec/pipeline/orchestrator.py`
- Pattern: Orchestrator with dynamic phase selection based on complexity
-
-**WorktreeManager:**
- Purpose: Git worktree isolation for safe parallel builds
- Examples: `apps/backend/core/worktree.py`
- Pattern: Each spec gets isolated worktree branch (`auto-claude/{spec-name}`)
-
-**SecurityProfile:**
- Purpose: Dynamic command allowlist based on project analysis
- Examples: `apps/backend/project_analyzer.py`, `apps/backend/security/`
- Pattern: Base + stack-specific + custom commands cached in `.auto-claude-security.json`
-
-**IPC Handlers:**
- Purpose: Bridge between Electron renderer and backend services
- Examples: `apps/frontend/src/main/ipc-handlers/`
- Pattern: Domain-specific handler modules registered via `ipc-setup.ts`
-
-## Entry Points
-
-**Backend CLI:**
- Location: `apps/backend/run.py`
- Triggers: Terminal, frontend subprocess spawn, direct invocation
- Responsibilities: Argument parsing, command routing to `cli/` modules
-
-**Electron Main:**
- Location: `apps/frontend/src/main/index.ts`
- Triggers: Application launch
- Responsibilities: Window creation, IPC setup, service initialization
-
-**Renderer Entry:**
- Location: `apps/frontend/src/renderer/main.tsx`
- Triggers: Window load
- Responsibilities: React app mount, store initialization
-
-**Spec Pipeline:**
- Location: `apps/backend/spec/pipeline/orchestrator.py:SpecOrchestrator`
- Triggers: CLI `--task`, frontend task creation
- Responsibilities: Dynamic phase execution for spec creation
-
-**Agent Loop:**
- Location: `apps/backend/agents/coder.py:run_autonomous_agent()`
- Triggers: CLI `--spec 001`, frontend build start
- Responsibilities: Subtask iteration, session management, recovery
-
-## Error Handling
-
-**Strategy:** Multi-level error handling with recovery support
-
-**Patterns:**
- Agent sessions: `RecoveryManager` tracks state for resumption after interruption
- Security validation: Pre-tool-use hooks reject dangerous commands before execution
- QA loop: Escalation to human review after max iterations (`MAX_QA_ITERATIONS`)
- Git operations: Retry with exponential backoff for network errors
- Frontend: Error boundaries with toast notifications
-
-## Cross-Cutting Concerns
-
-**Logging:**
- Backend: Python `logging` module with task-specific loggers (`task_logger/`)
- Frontend: Electron app logger (`app-logger.ts`), Sentry integration
-
-**Validation:**
- Command security: `security/` validators with dynamic allowlists
- Spec validation: `spec/validate_pkg/` for implementation plan schema
- Tool input: `security/tool_input_validator.py` for Claude tool arguments
-
-**Authentication:**
- OAuth flow: `core/auth.py` manages Claude OAuth tokens
- Token storage: Keychain (macOS), Credential Manager (Windows), encrypted file (Linux)
- Token validation: Pre-SDK-call validation to prevent encrypted token errors
-
-**Internationalization:**
- Frontend: `react-i18next` with namespace-organized JSON files
- Location: `apps/frontend/src/shared/i18n/locales/{en,fr}/`

-# Codebase Concerns
-
-**Analysis Date:** 2026-01-19
-
-## Tech Debt
-
-**Large File Complexity:**
- Issue: Several core files exceed 1000+ lines, indicating potential need for further modularization
- Files:
-  - `apps/backend/core/workspace.py` (2096 lines) - Already refactored but remains large
-  - `apps/backend/runners/github/orchestrator.py` (1607 lines)
-  - `apps/backend/core/worktree.py` (1404 lines)
-  - `apps/backend/runners/github/context_gatherer.py` (1292 lines)
-  - `apps/frontend/src/main/ipc-handlers/task/worktree-handlers.ts` (3149 lines)
-  - `apps/frontend/src/main/ipc-handlers/github/pr-handlers.ts` (2874 lines)
- Impact: Difficult to navigate, test, and maintain; increases risk of merge conflicts
- Fix approach: Continue modular extraction pattern (workspace.py partially done); extract sub-modules for GitHub orchestrator
-
-**Deprecated Modules Still in Codebase:**
- Issue: Deprecated code remains active and produces warnings
- Files:
-  - `apps/backend/runners/github/confidence.py` - Marked deprecated, uses DeprecationWarning
-  - `apps/frontend/src/main/terminal/terminal-manager.ts` - Contains deprecated sync methods
-  - `apps/frontend/src/main/terminal/session-handler.ts` - persistAllSessions deprecated
- Impact: Technical confusion, potential runtime warnings, maintenance burden
- Fix approach: Remove deprecated modules or complete migration to evidence-based validation
-
-**Global State / Module-Level Caches:**
- Issue: Multiple modules use global variables and module-level caches that are not thread-safe
- Files:
-  - `apps/backend/security/profile.py` (5 global variables for caching)
-  - `apps/backend/core/client.py` (_PROJECT_INDEX_CACHE, _CLAUDE_CLI_CACHE)
-  - `apps/backend/core/io_utils.py` (_pipe_broken global)
-  - `apps/backend/core/sentry.py` (_sentry_initialized, _sentry_enabled)
-  - `apps/backend/task_logger/utils.py` (_current_logger global)
- Impact: Potential race conditions in multi-threaded scenarios; difficult to test in isolation
- Fix approach: Convert to class-based singletons with proper locking; use thread-local storage where appropriate
-
-**Incomplete TODO Implementation:**
- Issue: Critical features have TODO placeholders
- Files:
-  - `apps/backend/core/workspace.py:1578` - `_record_merge_completion` not implemented
-  - `apps/backend/merge/conflict_analysis.py:272-283` - Advanced implicit conflict detection not implemented
-  - `apps/frontend/src/renderer/stores/settings-store.ts:214` - i18n keys not implemented
-  - `apps/frontend/src/renderer/components/ideation/EnvConfigModal.tsx:1` - Props interface not defined
- Impact: Missing functionality, potential runtime issues
- Fix approach: Implement or remove features; document if intentionally deferred
-
-**Empty Exception Handlers:**
- Issue: Many `pass` statements in exception handlers swallow errors silently
- Files: 237+ instances of `pass` after exception handling across backend
- Locations include:
-  - `apps/backend/core/worktree.py:448`
-  - `apps/backend/services/orchestrator.py:384, 396, 411, 423`
-  - `apps/backend/cli/workspace_commands.py:339-359` (multiple)
-  - `apps/backend/runners/github/memory_integration.py` (multiple)
- Impact: Silent failures make debugging difficult; errors may propagate unexpectedly
- Fix approach: Add logging to catch blocks; re-raise critical exceptions; document intentional suppressions
-
-## Known Bugs
-
-**Status Flip-Flop Bug (Task Store):**
- Symptoms: Task status may incorrectly change between terminal states
- Files: `apps/frontend/src/renderer/stores/task-store.ts:278, 282, 324, 346`
- Trigger: Phase transitions in updateTaskFromPlan
- Workaround: Multiple FIX comments added inline; logic guards terminal phases
-
-**BulkPRDialog Error Detection:**
- Symptoms: String-based error detection is fragile
- Files: `apps/frontend/src/renderer/components/BulkPRDialog.tsx:32`
- Trigger: API error messages changing format
- Workaround: None - TODO comment acknowledges the issue
-
-## Security Considerations
-
-**Shell=True Usage:**
- Risk: Command injection if inputs not properly sanitized
- Files:
-  - `apps/backend/core/git_executable.py:134` - Windows 'where' command
-  - `apps/backend/core/gh_executable.py:61` - Windows 'where' command
- Current mitigation: Limited to Windows platform detection, not user-controlled input
- Recommendations: Document why shell=True is required; ensure no user input reaches these calls
-
-**Subprocess Execution Spread Across Codebase:**
- Risk: Inconsistent security validation; command injection if not properly controlled
- Files: 50+ files with subprocess.run/Popen calls
- Current mitigation: Security hooks in `apps/backend/security/hooks.py`; allowlist in project_analyzer
- Recommendations: Consolidate subprocess calls through centralized wrappers; audit all subprocess calls
-
-**Environment Variable Handling:**
- Risk: Sensitive data exposure through env vars
- Files: 100+ os.environ references across backend
- Current mitigation: Token validation in `apps/backend/core/auth.py`; encrypted token detection
- Recommendations: Audit all env var usage; ensure secrets are not logged; use secure storage APIs
-
-**Token Decryption Not Implemented:**
- Risk: Encrypted tokens fail silently, requiring manual workarounds
- Files: `apps/backend/core/auth.py:103-228`
- Current mitigation: Clear error messages directing users to alternatives
- Recommendations: Implement cross-platform token decryption or improve error UX
-
-## Performance Bottlenecks
-
-**Blocking Sleep Calls:**
- Problem: time.sleep() calls block threads
- Files:
-  - `apps/backend/core/workspace/models.py:129, 218`
-  - `apps/backend/core/worktree.py:95, 106`
-  - `apps/backend/services/orchestrator.py:451`
-  - `apps/backend/runners/github/file_lock.py:172`
-  - `apps/backend/runners/gitlab/glab_client.py:168`
- Cause: Synchronous retry logic with exponential backoff
- Improvement path: Convert to async operations where possible; use asyncio.sleep for async code
-
-**Project Index Cache TTL:**
- Problem: 5-minute TTL may cause stale data or unnecessary reloads
- Files: `apps/backend/core/client.py:43` (_CACHE_TTL_SECONDS = 300)
- Cause: Fixed TTL doesn't adapt to project activity
- Improvement path: Implement file-watcher invalidation; make TTL configurable
-
-**Security Profile Cache:**
- Problem: Module-level cache with no size limits
- Files: `apps/backend/security/profile.py:23-27`
- Cause: Global state without eviction policy
- Improvement path: Add LRU eviction; consider bounded cache
-
-## Fragile Areas
-
-**Merge System:**
- Files:
-  - `apps/backend/core/workspace.py` (complex merge orchestration)
-  - `apps/backend/merge/` directory (conflict detection, resolution)
- Why fragile: Complex state machine for parallel merges; many edge cases in git operations
- Safe modification: Always test with multiple concurrent specs; use DEBUG=true for verbose logging
- Test coverage: Tests exist but may not cover all race conditions
-
-**GitHub Integration:**
- Files:
-  - `apps/backend/runners/github/orchestrator.py`
-  - `apps/backend/runners/github/rate_limiter.py`
-  - `apps/backend/runners/github/gh_client.py`
- Why fragile: External API dependencies; rate limiting complexity; async/await patterns
- Safe modification: Mock external calls in tests; test rate limit scenarios explicitly
- Test coverage: Good coverage in `tests/test_github_*.py`
-
-**Terminal Integration (Frontend):**
- Files:
-  - `apps/frontend/src/renderer/stores/terminal-store.ts`
-  - `apps/frontend/src/main/terminal/claude-integration-handler.ts`
- Why fragile: Complex state management; IPC communication; PTY lifecycle
- Safe modification: Test terminal creation/destruction cycles; watch for memory leaks
- Test coverage: Tests exist in `__tests__/` directories
-
-**Auth/Token Handling:**
- Files: `apps/backend/core/auth.py` (898 lines)
- Why fragile: Platform-specific code paths; external dependency on Claude CLI; keyring integration
- Safe modification: Test on all platforms; verify OAuth flow end-to-end
- Test coverage: `tests/test_auth.py` exists
-
-## Scaling Limits
-
-**Concurrent Agent Sessions:**
- Current capacity: Limited by Claude SDK rate limits and system resources
- Limit: No explicit session pooling or queuing
- Scaling path: Implement session pool; add retry queues for rate limits
-
-**Graphiti Memory Database:**
- Current capacity: LadybugDB (embedded Kuzu) - single-process access
- Limit: No concurrent write support across multiple processes
- Scaling path: Consider distributed graph database for multi-user scenarios
-
-## Dependencies at Risk
-
-**Deprecated Python Packages:**
- Risk: `secretstorage` on Linux has complex DBus dependencies
- Impact: Installation failures on minimal Linux systems
- Migration plan: Document fallback to .env storage; improve error messages
-
-**Platform-Specific Code:**
- Risk: Windows/macOS/Linux code paths diverge
- Impact: Platform-specific bugs (documented in CLAUDE.md)
- Migration plan: Centralized platform abstraction in `apps/backend/core/platform/`
-
-## Missing Critical Features
-
-**Implicit Conflict Detection:**
- Problem: Function rename + usage conflicts not detected
- Blocks: Accurate parallel merge conflict resolution
- Files: `apps/backend/merge/conflict_analysis.py:272-283`
-
-**_record_merge_completion:**
- Problem: Merge completion not recorded for timeline tracking
- Blocks: Full merge history audit trail
- Files: `apps/backend/core/workspace.py:1578`
-
-## Test Coverage Gaps
-
-**Async Code Testing:**
- What's not tested: Many async functions have limited coverage
- Files: 70+ files with async functions, 92+ with await statements
- Risk: Race conditions in async code may go unnoticed
- Priority: High - async bugs are hard to reproduce
-
-**Platform-Specific Paths:**
- What's not tested: Windows-specific code paths on Linux CI
- Files: Platform detection in `apps/backend/core/platform/__init__.py`
- Risk: Windows-only bugs not caught until user reports
- Priority: Medium - CI now runs on all platforms per CLAUDE.md
-
-**Global State Reset:**
- What's not tested: Cache invalidation edge cases
- Files: All files with module-level caches
- Risk: State leakage between tests
- Priority: Medium - add cache reset fixtures
-
-**Exception Handler Behavior:**
- What's not tested: Error paths through empty except blocks
- Files: 237+ `pass` statements in exception handlers
- Risk: Silent failures in production
- Priority: High - add tests that trigger exception paths

-# Coding Conventions
-
-**Analysis Date:** 2026-01-19
-
-## Naming Patterns
-
-**Files:**
- Python: `snake_case.py` (e.g., `project_analyzer.py`, `qa_report.py`)
- TypeScript: `kebab-case.ts` or `PascalCase.tsx` for React components
- Test files: `test_*.py` (Python), `*.test.ts` (TypeScript)
- Config files: lowercase with extension (e.g., `ruff.toml`, `tsconfig.json`)
-
-**Functions:**
- Python: `snake_case` (e.g., `validate_command()`, `get_security_profile()`)
- TypeScript: `camelCase` (e.g., `detectRateLimit()`, `parsePhaseEvent()`)
-
-**Variables:**
- Python: `snake_case` for locals, `UPPER_SNAKE_CASE` for constants
- TypeScript: `camelCase` for locals, `UPPER_SNAKE_CASE` for constants
-
-**Classes/Types:**
- Python: `PascalCase` (e.g., `SecurityProfile`, `ClaudeSDKClient`)
- TypeScript: `PascalCase` for types/interfaces (e.g., `ExecutionParserContext`)
-
-**Constants:**
- Module-level: `UPPER_SNAKE_CASE` (e.g., `DEFAULT_UTILITY_MODEL`, `SAFE_COMMANDS`)
- Private cache variables: `_UPPER_SNAKE_CASE` (e.g., `_PROJECT_INDEX_CACHE`)
-
-## Code Style
-
-**Formatting - Python (Backend):**
- Tool: Ruff (v0.14.10 via pre-commit)
- Quote style: Double quotes
- Indent style: Spaces (4 spaces per PEP 8)
- Line endings: Auto
- Key rules enabled:
-  - `E`, `W` (pycodestyle)
-  - `F` (Pyflakes)
-  - `I` (isort)
-  - `B` (flake8-bugbear)
-  - `C4` (flake8-comprehensions)
-  - `UP` (pyupgrade)
-
-**Formatting - TypeScript (Frontend):**
- Tool: Biome (v2.3.11)
- Commands:
-  ```bash
-  cd apps/frontend && npx biome check --write .  # Lint + format
-  ```
- TypeScript compiler: `tsc --noEmit` for type checking
- Strict mode enabled in `tsconfig.json`
-
-**Linting:**
- Python: Ruff handles both linting and formatting
- TypeScript: Biome handles both (replaced ESLint for 15-25x faster performance)
-
-## Import Organization
-
-**Python Order (enforced by isort via Ruff):**
-1. Standard library imports (`import os`, `import json`)
-2. Third-party imports (`from claude_agent_sdk import ...`)
-3. Local imports (`from core.client import create_client`)
-
-**TypeScript Order:**
-1. React/external library imports
-2. Local component imports
-3. Type imports
-
-**Path Aliases (TypeScript):**
-```typescript
-// tsconfig.json paths
-"@/*": ["src/renderer/*"]
-"@shared/*": ["src/shared/*"]
-"@preload/*": ["src/preload/*"]
-"@features/*": ["src/renderer/features/*"]
-"@components/*": ["src/renderer/shared/components/*"]
-"@hooks/*": ["src/renderer/shared/hooks/*"]
-"@lib/*": ["src/renderer/shared/lib/*"]
-```
-
-## Error Handling
-
-**Python Patterns:**
-```python
-# Try-except with specific exceptions
-try:
-    result = subprocess.run(cmd, capture_output=True, timeout=5)
-except (subprocess.TimeoutExpired, FileNotFoundError, OSError) as e:
-    logger.debug(f"Operation failed: {e}")
-    return None
-
-# Validation with early return
-def validate_something(value: str) -> tuple[bool, str]:
-    if not value:
-        return False, "Value is required"
-    if invalid_condition:
-        return False, "Value is invalid because..."
-    return True, ""
-```
-
-**TypeScript Patterns:**
-```typescript
-// Result object pattern for detection functions
-interface DetectionResult {
-  isDetected: boolean;
-  message?: string;
-  details?: Record<string, unknown>;
-}
-
-function detectSomething(input: string): DetectionResult {
-  if (!input) {
-    return { isDetected: false };
-  }
-  // Detection logic...
-  return { isDetected: true, message: "Detected condition X" };
-}
-```
-
-## Logging
-
-**Python Framework:** Standard library `logging`
-
-**Patterns:**
-```python
-import logging
-
-logger = logging.getLogger(__name__)
-
-# Debug for verbose/diagnostic info
-logger.debug(f"Cache HIT for {key}")
-
-# Info for significant operations
-logger.info(f"Found Claude CLI: {path} (v{version})")
-
-# Warning for recoverable issues
-logger.warning(f"Invalid configuration: {value}, using default")
-
-# Error with context
-logger.error(f"Failed to process {file}: {error}")
-```
-
-**TypeScript Logging:** Console-based in development, suppressed in tests.
-
-## Comments
-
-**When to Comment:**
- Public functions: Always document with docstrings/JSDoc
- Complex algorithms: Explain the "why" not the "what"
- Security-related code: Explain security implications
- Workarounds: Reference issue numbers
-
-**Python Docstrings:**
-```python
-def create_client(
-    project_dir: Path,
-    spec_dir: Path,
-    model: str,
-    agent_type: str = "coder",
-) -> ClaudeSDKClient:
-    """
-    Create a Claude Agent SDK client with multi-layered security.
-
-    Uses AGENT_CONFIGS for phase-aware tool and MCP server configuration.
-
-    Args:
-        project_dir: Root directory for the project (working directory)
-        spec_dir: Directory containing the spec (for settings file)
-        model: Claude model to use
-        agent_type: Agent type identifier from AGENT_CONFIGS
-
-    Returns:
-        Configured ClaudeSDKClient
-
-    Raises:
-        ValueError: If agent_type is not found in AGENT_CONFIGS
-    """
-```
-
-**TypeScript JSDoc:**
-```typescript
-/**
- * Detect rate limit from CLI output.
- *
- * @param output - Raw CLI output string
- * @returns Detection result with isRateLimited flag and optional resetTime
- */
-function detectRateLimit(output: string): RateLimitResult {
-  // ...
-}
-```
-
-## Function Design
-
-**Size:** Keep functions focused on a single responsibility. Functions over 50 lines should be considered for splitting.
-
-**Parameters:**
- Python: Use type hints for all parameters
- TypeScript: Use explicit types, avoid `any`
- Default values for optional parameters
- Keyword arguments for functions with 3+ parameters
-
-**Return Values:**
- Python: Use tuple for multiple returns `-> tuple[bool, str]`
- TypeScript: Use result objects for complex returns
- Always annotate return types
-
-## Module Design
-
-**Python Exports:**
- Use `__all__` in `__init__.py` to control public API
- Prefix internal functions/classes with underscore
-
-**TypeScript Barrel Files:**
-```typescript
-// index.ts barrel export pattern
-export { ExecutionPhaseParser } from './execution-phase-parser';
-export { IdeationPhaseParser } from './ideation-phase-parser';
-export type { ExecutionParserContext } from './types';
-```
-
-## Security Conventions
-
-**Validation First:**
-```python
-# Always validate input before processing
-def _validate_custom_mcp_server(server: dict) -> bool:
-    """Validate a custom MCP server configuration for security."""
-    if not isinstance(server, dict):
-        return False
-
-    # Required fields
-    required_fields = {"id", "name", "type"}
-    if not all(field in server for field in required_fields):
-        return False
-
-    # Blocklist dangerous commands
-    DANGEROUS_COMMANDS = {"bash", "sh", "cmd", "powershell"}
-    if command in DANGEROUS_COMMANDS:
-        logger.warning(f"Rejected dangerous command: {command}")
-        return False
-
-    return True
-```
-
-**Sensitive Commands:** Always use allowlist approach, never blocklist alone.
-
-## Internationalization (Frontend)
-
-**Always use i18n for user-facing text:**
-```tsx
-import { useTranslation } from 'react-i18next';
-
-const { t } = useTranslation(['navigation', 'common']);
-
-// Correct
-<span>{t('navigation:items.githubPRs')}</span>
-
-// Wrong - hardcoded string
-<span>GitHub PRs</span>
-```
-
-**Translation file structure:**
- `apps/frontend/src/shared/i18n/locales/en/*.json`
- `apps/frontend/src/shared/i18n/locales/fr/*.json`
-
-## Platform-Specific Code
-

-## Test Structure
-
-**Python - pytest Pattern:**
-```python
-#!/usr/bin/env python3
-"""
-Tests for Security System
-=========================
-
-Tests the security.py module functionality including:
- Command extraction and parsing
- Command allowlist validation
-"""
-
-import pytest
-from security import validate_command, extract_commands
-
-
-class TestCommandExtraction:
-    """Tests for command extraction from shell strings."""
-
-    def test_simple_command(self):
-        """Extracts single command correctly."""
-        commands = extract_commands("ls -la")
-        assert commands == ["ls"]

-            allowed, reason = validate_command(cmd, temp_dir)
-            assert allowed is True, f"{cmd} should be allowed"
-```
-
-**TypeScript - Vitest Pattern:**
-```typescript
-/**
- * Phase Parsers Tests
- * ====================
- * Unit tests for the specialized phase parsers.
- */
-
-import { describe, it, expect, vi, beforeEach, afterEach } from 'vitest';
-import { ExecutionPhaseParser } from '../agent/parsers';
-
-describe('ExecutionPhaseParser', () => {
-  const parser = new ExecutionPhaseParser();
-
-  const makeContext = (currentPhase: string): ExecutionParserContext => ({
-    currentPhase,
-    isTerminal: currentPhase === 'complete'
-  });

-      const result = parser.parse(log, makeContext('complete'));
-
-      expect(result).toBeNull();
-    });
-  });
-});
-```
-
-## Mocking
-
-**Python - pytest fixtures and unittest.mock:**
-```python
-from unittest.mock import MagicMock, patch
-
-@pytest.fixture
-def mock_task_logger():
-    """Mock TaskLogger for testing PhaseExecutor."""
-    logger = MagicMock()
-    logger.log = MagicMock()
-    logger.start_phase = MagicMock()
-    logger.end_phase = MagicMock()
-    return logger
-
-# Using patch decorator
-@patch('core.client.find_claude_cli')
-def test_client_creation(mock_find_cli):
-    mock_find_cli.return_value = '/usr/local/bin/claude'
-    # Test code...
-
-# Using monkeypatch fixture
-def test_with_env_var(monkeypatch):
-    monkeypatch.setenv("CLAUDE_CLI_PATH", "/custom/path")
-    # Test code...
-```
-
-**TypeScript - Vitest vi.mock:**
-```typescript
-// Mock at module level (hoisted)
-vi.mock('../claude-profile-manager', () => ({
-  getClaudeProfileManager: vi.fn(() => ({
-    getActiveProfile: vi.fn(() => ({
-      id: 'test-profile-id',
-      name: 'Test Profile'
-    })),
-    recordRateLimitEvent: vi.fn()
-  }))
-}));
-
-describe('Rate Limit Detector', () => {
-  beforeEach(() => {
-    vi.resetModules();
-  });
-
-  afterEach(() => {
-    vi.clearAllMocks();
-  });
-
-  it('should detect rate limit', async () => {
-    const { detectRateLimit } = await import('../rate-limit-detector');
-    const result = detectRateLimit('Limit reached · resets Dec 17');
-    expect(result.isRateLimited).toBe(true);
-  });
-});
-```
-
-**What to Mock:**
- External APIs (Claude SDK, GitHub API)
- File system operations in unit tests
- Network requests
- System time (for time-sensitive tests)
- Heavy dependencies (databases, MCP servers)
-
-**What NOT to Mock:**
- Pure functions under test
- Simple data transformations
- Validation logic
-
-## Fixtures and Factories
-
-**Python Fixtures (conftest.py):**
-```python
-@pytest.fixture
-def temp_dir() -> Generator[Path, None, None]:
-    """Create a temporary directory that's cleaned up after the test."""
-    temp_path = Path(tempfile.mkdtemp())
-    yield temp_path
-    shutil.rmtree(temp_path, ignore_errors=True)
-
-@pytest.fixture
-def temp_git_repo(temp_dir: Path) -> Generator[Path, None, None]:
-    """Create a temporary git repository with initial commit."""
-    # Clear git environment variables to isolate from parent repo
-    orig_env = {}
-    git_vars_to_clear = ["GIT_DIR", "GIT_WORK_TREE", "GIT_INDEX_FILE"]
-    for key in git_vars_to_clear:
-        orig_env[key] = os.environ.get(key)
-        if key in os.environ:
-            del os.environ[key]
-
-    try:
-        subprocess.run(["git", "init"], cwd=temp_dir, capture_output=True)
-        subprocess.run(["git", "config", "user.email", "test@example.com"], cwd=temp_dir)
-        # ...
-        yield temp_dir
-    finally:
-        # Restore environment
-        for key, value in orig_env.items():
-            if value is None:
-                os.environ.pop(key, None)
-            else:
-                os.environ[key] = value
-
-@pytest.fixture
-def python_project(temp_git_repo: Path) -> Path:
-    """Create a sample Python project structure."""
-    (temp_git_repo / "pyproject.toml").write_text(toml_content)
-    (temp_git_repo / "app" / "__init__.py").write_text("# App module\n")
-    return temp_git_repo
-```
-
-**TypeScript Setup (setup.ts):**
-```typescript
-import { vi, beforeEach, afterEach } from 'vitest';
-
-// Mock localStorage for tests
-const localStorageMock = (() => {
-  let store: Record<string, string> = {};
-  return {
-    getItem: vi.fn((key: string) => store[key] || null),
-    setItem: vi.fn((key: string, value: string) => { store[key] = value; }),
-    clear: vi.fn(() => { store = {}; })
-  };
-})();
-
-Object.defineProperty(global, 'localStorage', { value: localStorageMock });
-
-// Mock window.electronAPI for renderer tests
-if (typeof window !== 'undefined') {
-  (window as any).electronAPI = {
-    getTasks: vi.fn(),
-    createTask: vi.fn(),
-    getSettings: vi.fn(),
-    // ...
-  };
-}
-
-beforeEach(() => {
-  localStorageMock.clear();
-});
-
-afterEach(() => {
-  vi.clearAllMocks();
-  vi.resetModules();
-});
-```
-
-**Sample Data (test_fixtures.py):**
-```python
-SAMPLE_REACT_COMPONENT = '''import React from 'react';
-import { useState } from 'react';
-
-function App() {
-  const [count, setCount] = useState(0);
-  return <div><h1>Hello World</h1></div>;
-}
-export default App;
-'''
-
-SAMPLE_PYTHON_MODULE = '''"""Sample Python module."""
-import os
-from pathlib import Path
-
-def hello():
-    """Say hello."""
-    print("Hello")
-'''
-```
-
-## Coverage
-
-**Requirements:** No enforced minimum threshold, but aim for meaningful coverage
-
-**View Coverage:**
-```bash
-# Backend
-apps/backend/.venv/bin/pytest tests/ --cov=apps/backend --cov-report=html
-
-# Frontend
-cd apps/frontend && npm run test:coverage
-```
-
-**Coverage Output:**
- Backend: `.coverage` file, HTML report in `htmlcov/`
- Frontend: `coverage/` directory with JSON, text, and HTML reports
-
-## Test Types
-
-**Unit Tests:**
- Test individual functions/classes in isolation
- Mock external dependencies
- Fast execution (sub-second)
- Location: `tests/test_*.py`, `src/**/*.test.ts`
-
-**Integration Tests:**
- Test interactions between components
- May use real file system, git repos
- Slower execution
- Markers: `@pytest.mark.integration` (Python)
- Location: `tests/` (Python), `src/__tests__/integration/` (TypeScript)
-
-**E2E Tests (Frontend):**
- Framework: Playwright (configured but limited use)
- Config: `apps/frontend/e2e/playwright.config.ts`
- Run: `npm run test:e2e`
-
-## Common Patterns
-
-**Async Testing (Python):**
-```python
-import pytest
-
-@pytest.mark.asyncio
-async def test_async_function():
-    result = await some_async_operation()
-    assert result is not None
-
-# pytest.ini enables asyncio_mode = auto
-# No need to manually mark simple async tests
-```
-
-**Async Testing (TypeScript):**
-```typescript
-it('should handle async operation', async () => {
-  const { detectRateLimit } = await import('../rate-limit-detector');
-  const result = detectRateLimit('some output');
-  expect(result.isRateLimited).toBe(false);
-});
-```
-
-**Error Testing (Python):**
-```python
-def test_blocked_dangerous_command(self, temp_dir):
-    """Dangerous commands not in allowlist are blocked."""
-    allowed, reason = validate_command("rm -rf /", temp_dir)
-    assert allowed is False
-    assert "not allowed for safety" in reason
-
-def test_raises_on_invalid_input():
-    """Should raise ValueError on invalid input."""
-    with pytest.raises(ValueError, match="Invalid configuration"):
-        process_config(None)
-```
-
-**Error Testing (TypeScript):**
-```typescript
-it('should return false for empty output', async () => {
-  const { detectRateLimit } = await import('../rate-limit-detector');
-  const result = detectRateLimit('');
-  expect(result.isRateLimited).toBe(false);
-});
-
-it('should handle malformed input gracefully', () => {
-  expect(() => parser.parse(null as any)).not.toThrow();
-});
-```
-
-**Parameterized Tests (Python):**
-```python
-@pytest.mark.parametrize("cmd,expected", [
-    ("ls -la", ["ls"]),
-    ("cat file | grep pattern", ["cat", "grep"]),
-    ("", []),
-])
-def test_extract_commands(cmd, expected):
-    assert extract_commands(cmd) == expected
-```
-
-**Parameterized Tests (TypeScript):**
-```typescript
-const testCases = [
-  'rate limit exceeded',
-  'usage limit reached',
-  'too many requests'
-];
-
-for (const output of testCases) {
-  const result = detectRateLimit(output);
-  expect(result.isRateLimited).toBe(true);
-}
-```
-
-## Pre-commit Testing
-
-**Configuration:** `.pre-commit-config.yaml`
-
-Tests run automatically on commit:
- Python: `pytest -m "not slow and not integration"` (fast tests only)
- TypeScript: Biome lint + TypeScript type check
-
-Skipped tests in pre-commit:
- `test_graphiti.py` (external dependencies)
- `test_worktree.py` (git-sensitive)
- `test_workspace.py` (Windows path issues)
-
-## Test Markers (Python)
-
-```python
-@pytest.mark.slow       # Long-running tests
-@pytest.mark.integration  # Integration tests
-@pytest.mark.asyncio    # Async tests (auto-applied via config)
-```
-
-**Run specific markers:**
-```bash
-# Skip slow tests
-pytest tests/ -m "not slow"
-
-# Run only integration tests
-pytest tests/ -m "integration"
-```

 # CLAUDE.md

-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+This file provides guidance to Claude Code when working with this repository.

-## Project Overview
+Auto Claude is an autonomous multi-agent coding framework that plans, builds, and validates software for you. It's a monorepo with a Python backend (CLI + agent logic) and an Electron/React frontend (desktop UI).

-Auto Claude is a multi-agent autonomous coding framework that builds software through coordinated AI agent sessions. It uses the Claude Agent SDK to run agents in isolated workspaces with security controls.
+> **Deep-dive reference:** [ARCHITECTURE.md](shared_docs/ARCHITECTURE.md) | **Frontend contributing:** [apps/frontend/CONTRIBUTING.md](apps/frontend/CONTRIBUTING.md)

-**CRITICAL: All AI interactions use the Claude Agent SDK (`claude-agent-sdk` package), NOT the Anthropic API directly.**
+## Product Overview
+
+Auto Claude is a desktop application (+ CLI) where users describe a goal and AI agents autonomously handle planning, implementation, and QA validation. All work happens in isolated git worktrees so the main branch stays safe.
+
+**Core workflow:** User creates a task → Spec creation pipeline assesses complexity and writes a specification → Planner agent breaks it into subtasks → Coder agent implements (can spawn parallel subagents) → QA reviewer validates → QA fixer resolves issues → User reviews and merges.
+
+**Main features:**
+
+- **Autonomous Tasks** — Multi-agent pipeline (planner, coder, QA) that builds features end-to-end
+- **Kanban Board** — Visual task management from planning through completion
+- **Agent Terminals** — Up to 12 parallel AI-powered terminals with task context injection
+- **Insights** — AI chat interface for exploring and understanding your codebase
+- **Roadmap** — AI-assisted feature planning with strategic roadmap generation
+- **Ideation** — Discover improvements, performance issues, and security vulnerabilities
+- **GitHub/GitLab Integration** — Import issues, AI-powered investigation, PR/MR review and creation
+- **Changelog** — Generate release notes from completed tasks
+- **Memory System** — Graphiti-based knowledge graph retains insights across sessions
+- **Isolated Workspaces** — Git worktree isolation for every build; AI-powered semantic merge
+- **Flexible Authentication** — Use a Claude Code subscription (OAuth) or API profiles with any Anthropic-compatible endpoint (e.g., Anthropic API, z.ai for GLM models)
+- **Multi-Account Swapping** — Register multiple Claude accounts; when one hits a rate limit, Auto Claude automatically switches to an available account
+- **Cross-Platform** — Native desktop app for Windows, macOS, and Linux with auto-updates
+
+## Critical Rules
+
+**Claude Agent SDK only** — All AI interactions use `claude-agent-sdk`. NEVER use `anthropic.Anthropic()` directly. Always use `create_client()` from `core.client`.
+
+**i18n required** — All frontend user-facing text MUST use `react-i18next` translation keys. Never hardcode strings in JSX/TSX. Add keys to both `en/*.json` and `fr/*.json`.
+
+**Platform abstraction** — Never use `process.platform` directly. Import from `apps/frontend/src/main/platform/` or `apps/backend/core/platform/`. CI tests all three platforms.
+
+**No time estimates** — Never provide duration predictions. Use priority-based ordering instead.
+
+**PR target** — Always target the `develop` branch for PRs to AndyMik90/Auto-Claude, NOT `main`.
+
+## Memory (claude-mem)
+
+This project uses claude-mem for persistent memory across sessions. MCP search tools are available — use them proactively:
+
+- **Before modifying code** — Search for past work on the same files/features: `search(query="<file or feature>")`. Check if there are known bugs, decisions, or patterns to follow.
+- **When debugging** — Search for prior encounters with the same error or symptom: `search(query="<error message>", type="bugfix")`.
+- **When making architectural decisions** — Check for past decisions: `search(query="<topic>", type="decision")`.
+- **When resuming work** — Use `timeline(anchor=<recent_id>)` to understand where things left off.
+
+Follow the 3-layer workflow: `search` (cheap index) → `timeline` (context) → `get_observations` (full details only for relevant IDs). Never fetch full details without filtering first.

-**When working with AI/LLM code:**
- Look in `apps/backend/core/client.py` for the Claude SDK client setup
- Reference `apps/backend/agents/` for working agent implementations
- Check `apps/backend/spec_agents/` for spec creation agent examples
- NEVER use `anthropic.Anthropic()` directly - always use `create_client()` from `core.client`
-
-**Frontend (Electron Desktop App):**
- Built with Electron, React, TypeScript
- AI agents can perform E2E testing using the Electron MCP server
- When bug fixing or implementing features, use the Electron MCP server for automated testing
- See "End-to-End Testing" section below for details

-## Architecture
+## Backend Development

-### Core Pipeline
+### Claude Agent SDK Usage

-**Spec Creation (spec_runner.py)** - Dynamic 3-8 phase pipeline based on task complexity:
- SIMPLE (3 phases): Discovery → Quick Spec → Validate
- STANDARD (6-7 phases): Discovery → Requirements → [Research] → Context → Spec → Plan → Validate
- COMPLEX (8 phases): Full pipeline with Research and Self-Critique phases
+Client: `apps/backend/core/client.py` — `create_client()` returns a configured `ClaudeSDKClient` with security hooks, tool permissions, and MCP server integration.

-**Implementation (run.py → agent.py)** - Multi-session build:
-1. Planner Agent creates subtask-based implementation plan
-2. Coder Agent implements subtasks (can spawn subagents for parallel work)
-3. QA Reviewer validates acceptance criteria (can perform E2E testing via Electron MCP for frontend changes)
-4. QA Fixer resolves issues in a loop (with E2E testing to verify fixes)
+Model and thinking level are user-configurable (via the Electron UI settings or CLI override). Use `phase_config.py` helpers to resolve the correct values:

-### Key Components (apps/backend/)
+```python
+from core.client import create_client
+from phase_config import get_phase_model, get_phase_thinking_budget

-**Core Infrastructure:**
- **core/client.py** - Claude Agent SDK client factory with security hooks and tool permissions
- **core/security.py** - Dynamic command allowlisting based on detected project stack
- **core/auth.py** - OAuth token management for Claude SDK authentication
- **agents/** - Agent implementations (planner, coder, qa_reviewer, qa_fixer)
- **spec_agents/** - Spec creation agents (gatherer, researcher, writer, critic)
+# Resolve model/thinking from user settings (Electron UI or CLI override)
+phase_model = get_phase_model(spec_dir, "coding", cli_model=None)
+phase_thinking = get_phase_thinking_budget(spec_dir, "coding", cli_thinking=None)

-**Memory & Context:**
- **integrations/graphiti/** - Graphiti memory system (mandatory)
-  - `queries_pkg/graphiti.py` - Main GraphitiMemory class
-  - `queries_pkg/client.py` - LadybugDB client wrapper
-  - `queries_pkg/queries.py` - Graph query operations
-  - `queries_pkg/search.py` - Semantic search logic
-  - `queries_pkg/schema.py` - Graph schema definitions
- **graphiti_config.py** - Configuration and validation for Graphiti integration
- **graphiti_providers.py** - Multi-provider factory (OpenAI, Anthropic, Azure, Ollama, Google AI)
- **agents/memory_manager.py** - Session memory orchestration
+client = create_client(
+    project_dir=project_dir,
+    spec_dir=spec_dir,
+    model=phase_model,
+    agent_type="coder",          # planner | coder | qa_reviewer | qa_fixer
+    max_thinking_tokens=phase_thinking,
+)

-**Workspace & Security:**
- **cli/worktree.py** - Git worktree isolation for safe feature development
- **context/project_analyzer.py** - Project stack detection for dynamic tooling
- **auto_claude_tools.py** - Custom MCP tools integration
+# Run agent session (uses context manager + run_agent_session helper)
+async with client:
+    status, response = await run_agent_session(client, prompt, spec_dir)
+```

-**Integrations:**
- **linear_updater.py** - Optional Linear integration for progress tracking
- **runners/github/** - GitHub Issues & PRs automation
- **Electron MCP** - E2E testing integration for QA agents (Chrome DevTools Protocol)
-  - Enabled with `ELECTRON_MCP_ENABLED=true` in `.env`
-  - Allows QA agents to interact with running Electron app
-  - See "End-to-End Testing" section for details

 ### Spec Directory Structure

-Each spec in `.auto-claude/specs/XXX-name/` contains:
- `spec.md` - Feature specification
- `requirements.json` - Structured user requirements
- `context.json` - Discovered codebase context
- `implementation_plan.json` - Subtask-based plan with status tracking
- `qa_report.md` - QA validation results
- `QA_FIX_REQUEST.md` - Issues to fix (when rejected)
+Each spec in `.auto-claude/specs/XXX-name/` contains: `spec.md`, `requirements.json`, `context.json`, `implementation_plan.json`, `qa_report.md`, `QA_FIX_REQUEST.md`

-### Branching & Worktree Strategy
+### Memory System (Graphiti)

-Auto Claude uses git worktrees for isolated builds. All branches stay LOCAL until user explicitly pushes:
+Graph-based semantic memory in `integrations/graphiti/`. Configured through the Electron app's onboarding/settings UI (CLI users can alternatively set `GRAPHITI_ENABLED=true` in `.env`). See [ARCHITECTURE.md](shared_docs/ARCHITECTURE.md#memory-system) for details.

-```
-main (user's branch)
-└── auto-claude/{spec-name}  ← spec branch (isolated worktree)
-```
+## Frontend Development

-**Key principles:**
- ONE branch per spec (`auto-claude/{spec-name}`)
- Parallel work uses subagents (agent decides when to spawn)
- NO automatic pushes to GitHub - user controls when to push
- User reviews in spec worktree (`.worktrees/{spec-name}/`)
- Final merge: spec branch → main (after user approval)
+### Tech Stack

-**Workflow:**
-1. Build runs in isolated worktree on spec branch
-2. Agent implements subtasks (can spawn subagents for parallel work)
-3. User tests feature in `.worktrees/{spec-name}/`
-4. User runs `--merge` to add to their project
-5. User pushes to remote when ready

-### Contributing to Upstream
+### Path Aliases (tsconfig.json)

-**CRITICAL: When submitting PRs to AndyMik90/Auto-Claude, always target the `develop` branch, NOT `main`.**
+| Alias | Maps to |
+|-------|---------|
+| `@/*` | `src/renderer/*` |
+| `@shared/*` | `src/shared/*` |
+| `@preload/*` | `src/preload/*` |
+| `@features/*` | `src/renderer/features/*` |
+| `@components/*` | `src/renderer/shared/components/*` |
+| `@hooks/*` | `src/renderer/shared/hooks/*` |
+| `@lib/*` | `src/renderer/shared/lib/*` |

-**Correct workflow for contributions:**
-1. Fetch upstream: `git fetch upstream`
-2. Create feature branch from upstream/develop: `git checkout -b fix/my-fix upstream/develop`
-3. Make changes and commit with sign-off: `git commit -s -m "fix: description"`
-4. Push to your fork: `git push origin fix/my-fix`
-5. Create PR targeting `develop`: `gh pr create --repo AndyMik90/Auto-Claude --base develop`
+### State Management (Zustand)

-**Verify before PR:**
-```bash
-# Ensure only your commits are included
-git log --oneline upstream/develop..HEAD
-```
+All state lives in `src/renderer/stores/`. Key stores:

-### Security Model
+- `project-store.ts` — Active project, project list
+- `task-store.ts` — Tasks/specs management
+- `terminal-store.ts` — Terminal sessions and state
+- `settings-store.ts` — User preferences
+- `github/issues-store.ts`, `github/pr-review-store.ts` — GitHub integration
+- `insights-store.ts`, `roadmap-store.ts`, `kanban-settings-store.ts`

-Three-layer defense:
-1. **OS Sandbox** - Bash command isolation
-2. **Filesystem Permissions** - Operations restricted to project directory
-3. **Command Allowlist** - Dynamic allowlist from project analysis (security.py + project_analyzer.py)
+Main process also has stores: `src/main/project-store.ts`, `src/main/terminal-session-store.ts`

-Security profile cached in `.auto-claude-security.json`.
+### Styling

-### Claude Agent SDK Integration
+- **Tailwind CSS v4** with `@tailwindcss/postcss` plugin
+- **7 color themes** (Default, Dusk, Lime, Ocean, Retro, Neo + more) defined in `src/shared/constants/themes.ts`
+- Each theme has light/dark mode variants via CSS custom properties
+- Utility: `clsx` + `tailwind-merge` via `cn()` helper
+- Component variants: `class-variance-authority` (CVA)

-**CRITICAL: Auto Claude uses the Claude Agent SDK for ALL AI interactions. Never use the Anthropic API directly.**
+### IPC Communication

-**Client Location:** `apps/backend/core/client.py`
+Main ↔ Renderer communication via Electron IPC:
+- **Handlers:** `src/main/ipc-handlers/` — organized by domain (github, gitlab, ideation, context, etc.)
+- **Preload:** `src/preload/` — exposes safe APIs to renderer
+- Pattern: renderer calls via `window.electronAPI.*`, main handles in IPC handler modules

-The `create_client()` function creates a configured `ClaudeSDKClient` instance with:
- Multi-layered security (sandbox, permissions, security hooks)
- Agent-specific tool permissions (planner, coder, qa_reviewer, qa_fixer)
- Dynamic MCP server integration based on project capabilities
- Extended thinking token budget control
+### Agent Management (`src/main/agent/`)

-**Example usage in agents:**
-```python
-from core.client import create_client
+The frontend manages agent lifecycle end-to-end:
+- **`agent-queue.ts`** — Queue routing, prioritization, spec number locking
+- **`agent-process.ts`** — Spawns and manages agent subprocess communication
+- **`agent-state.ts`** — Tracks running agent state and status
+- **`agent-events.ts`** — Agent lifecycle events and state transitions

-# Create SDK client (NOT raw Anthropic API client)
-client = create_client(
-    project_dir=project_dir,
-    spec_dir=spec_dir,
-    model="claude-sonnet-4-5-20250929",
-    agent_type="coder",
-    max_thinking_tokens=None  # or 5000/10000/16000
-)
+### Claude Profile System (`src/main/claude-profile/`)

-# Run agent session
-response = client.create_agent_session(
-    name="coder-agent-session",
-    starting_message="Implement the authentication feature"
-)
-```
+Multi-profile credential management for switching between Claude accounts:
+- **`credential-utils.ts`** — OS credential storage (Keychain/Windows Credential Manager)
+- **`token-refresh.ts`** — OAuth token lifecycle and automatic refresh
+- **`usage-monitor.ts`** — API usage tracking and rate limiting per profile
+- **`profile-scorer.ts`** — Scores profiles by usage and availability

-**Why use the SDK:**
- Pre-configured security (sandbox, allowlists, hooks)
- Automatic MCP server integration (Context7, Linear, Graphiti, Electron, Puppeteer)
- Tool permissions based on agent role
- Session management and recovery
- Unified API across all agent types
+### Terminal System (`src/main/terminal/`)

-**Where to find working examples:**
- `apps/backend/agents/planner.py` - Planner agent
- `apps/backend/agents/coder.py` - Coder agent
- `apps/backend/agents/qa_reviewer.py` - QA reviewer
- `apps/backend/agents/qa_fixer.py` - QA fixer
- `apps/backend/spec_agents/` - Spec creation agents
+Full PTY-based terminal integration:
+- **`pty-daemon.ts`** / **`pty-manager.ts`** — Background PTY process management
+- **`terminal-lifecycle.ts`** — Session creation, cleanup, event handling
+- **`claude-integration-handler.ts`** — Claude SDK integration within terminals
+- Renderer: xterm.js 6 with WebGL, fit, web-links, serialize addons. Store: `terminal-store.ts`

-### Memory System
+## Code Quality

-**Graphiti Memory (Mandatory)** - `integrations/graphiti/`
+### Frontend
+- **Linting:** Biome (`npm run lint` / `npm run lint:fix`)
+- **Type checking:** `npm run typecheck` (strict mode)
+- **Pre-commit:** Husky + lint-staged runs Biome on staged `.ts/.tsx/.js/.jsx/.json`
+- **Testing:** Vitest + React Testing Library + jsdom

-Auto Claude uses Graphiti as its primary memory system with embedded LadybugDB (no Docker required):
+### Backend
+- **Linting:** Ruff
+- **Testing:** pytest (`apps/backend/.venv/bin/pytest tests/ -v`)

- **Graph database with semantic search** - Knowledge graph for cross-session context
- **Session insights** - Patterns, gotchas, discoveries automatically extracted
- **Multi-provider support:**
-  - LLM: OpenAI, Anthropic, Azure OpenAI, Ollama, Google AI (Gemini)
-  - Embedders: OpenAI, Voyage AI, Azure OpenAI, Ollama, Google AI
- **Modular architecture:** (`integrations/graphiti/queries_pkg/`)
-  - `graphiti.py` - Main GraphitiMemory class
-  - `client.py` - LadybugDB client wrapper
-  - `queries.py` - Graph query operations
-  - `search.py` - Semantic search logic
-  - `schema.py` - Graph schema definitions
+## i18n Guidelines

-**Configuration:**
- Set provider credentials in `apps/backend/.env` (see `.env.example`)
- Required env vars: `GRAPHITI_ENABLED=true`, `ANTHROPIC_API_KEY` or other provider keys
- Memory data stored in `.auto-claude/specs/XXX/graphiti/`
+All frontend UI text uses `react-i18next`. Translation files: `apps/frontend/src/shared/i18n/locales/{en,fr}/*.json`

-**Usage in agents:**
-```python
-from integrations.graphiti.memory import get_graphiti_memory
+**Namespaces:** `common`, `navigation`, `settings`, `dialogs`, `tasks`, `errors`, `onboarding`, `welcome`

-memory = get_graphiti_memory(spec_dir, project_dir)
-context = memory.get_context_for_session("Implementing feature X")
-memory.add_session_insight("Pattern: use React hooks for state")
-```
-
-## Development Guidelines
-
-### No Time Estimates
-
-**CRITICAL: Never provide time estimates or predictions for how long tasks will take.**
-
-AI-assisted development dramatically changes implementation timelines, making traditional estimates misleading. Avoid:
- Week/day/hour estimates (e.g., "Week 1: Foundation", "This will take 2-3 days")
- Phrases like "quick fix", "simple change", "this should be fast"
- Roadmaps with time-based phases
-
-Instead:
- Focus on **what** needs to be done, not **when**
- Break work into actionable steps without duration predictions
- Use priority-based ordering (High Impact, Low Effort) rather than time-based phases
- Let users judge timing for themselves based on their context
-
-```
-// ❌ WRONG - Time-based roadmap
-Week 1: Foundation
-Week 2: Prevention over Detection
-Week 3: Calibration
-
-// ✅ CORRECT - Priority-based ordering
-Phase 1: Foundation (High Impact, Low Effort)
-Phase 2: Prevention over Detection
-Phase 3: Calibration
-```
-
-### Frontend Internationalization (i18n)
-
-**CRITICAL: Always use i18n translation keys for all user-facing text in the frontend.**
-
-The frontend uses `react-i18next` for internationalization. All labels, buttons, messages, and user-facing text MUST use translation keys.
-
-**Translation file locations:**
- `apps/frontend/src/shared/i18n/locales/en/*.json` - English translations
- `apps/frontend/src/shared/i18n/locales/fr/*.json` - French translations
-
-**Translation namespaces:**
- `common.json` - Shared labels, buttons, common terms
- `navigation.json` - Sidebar navigation items, sections
- `settings.json` - Settings page content
- `dialogs.json` - Dialog boxes and modals
- `tasks.json` - Task/spec related content
- `errors.json` - Error messages (structured error information with substitution support)
- `onboarding.json` - Onboarding wizard content
- `welcome.json` - Welcome screen content
-
-**Usage pattern:**
 ```tsx
 import { useTranslation } from 'react-i18next';
-
-// In component
 const { t } = useTranslation(['navigation', 'common']);

-// Use translation keys, NOT hardcoded strings
-<span>{t('navigation:items.githubPRs')}</span>  // ✅ CORRECT
-<span>GitHub PRs</span>                          // ❌ WRONG
+<span>{t('navigation:items.githubPRs')}</span>     // CORRECT
+<span>GitHub PRs</span>                             // WRONG
+
+// With interpolation:
+<span>{t('errors:task.parseError', { error })}</span>
 ```

-**Error messages with substitution:**
+When adding new UI text: add keys to ALL language files, use `namespace:section.key` format.

-```tsx
-// For error messages with dynamic content, use interpolation
-const { t } = useTranslation(['errors']);
+## Cross-Platform

-// errors.json: { "task": { "parseError": "Failed to parse: {{error}}" } }
-<span>{t('errors:task.parseError', { error: errorMessage })}</span>
-```
+Supports Windows, macOS, Linux. CI tests all three.

-**When adding new UI text:**
-1. Add the translation key to ALL language files (at minimum: `en/*.json` and `fr/*.json`)
-2. Use `namespace:section.key` format (e.g., `navigation:items.githubPRs`)
-3. Never use hardcoded strings in JSX/TSX files
-
-### Cross-Platform Development
-
-**CRITICAL: This project supports Windows, macOS, and Linux. Platform-specific bugs are the #1 source of breakage.**
-
-#### The Problem
-
-When developers on macOS fix something using Mac-specific assumptions, it breaks on Windows. When Windows developers fix something, it breaks on macOS. This happens because:
-
-1. **CI only tested on Linux** - Platform-specific bugs weren't caught until after merge
-2. **Scattered platform checks** - `process.platform === 'win32'` checks were spread across 50+ files
-3. **Hardcoded paths** - Direct paths like `C:\Program Files` or `/opt/homebrew/bin` throughout code
-
-#### The Solution
-
-**1. Centralized Platform Abstraction**
-
-All platform-specific code now lives in dedicated modules:
-
- **Frontend:** `apps/frontend/src/main/platform/`
- **Backend:** `apps/backend/core/platform/`
-
-**Import from these modules instead of checking `process.platform` directly:**
-
-```typescript
-// ❌ WRONG - Direct platform check
-if (process.platform === 'win32') {
-  // Windows logic
-}
-
-// ✅ CORRECT - Use abstraction
-import { isWindows, getPathDelimiter } from './platform';
-
-if (isWindows()) {
-  // Windows logic
-}
-```
-
-**2. Multi-Platform CI**
-
-CI now tests on **all three platforms** (Windows, macOS, Linux). A PR cannot merge unless all platforms pass:
-
-```yaml
-# .github/workflows/ci.yml
-strategy:
-  matrix:
-    os: [ubuntu-latest, windows-latest, macos-latest]
-```
-
-**3. Platform Module API**
-
-The platform module provides:
+**Platform modules:** `apps/frontend/src/main/platform/` and `apps/backend/core/platform/`

 | Function | Purpose |
 |----------|---------|
 | `isWindows()` / `isMacOS()` / `isLinux()` | OS detection |
-| `getPathDelimiter()` | Get `;` (Windows) or `:` (Unix) |
-| `getExecutableExtension()` | Get `.exe` (Windows) or `` (Unix) |
-| `findExecutable(name)` | Find executables across platforms |
-| `getBinaryDirectories()` | Get platform-specific bin paths |
-| `requiresShell(command)` | Check if .cmd/.bat needs shell on Windows |
+| `getPathDelimiter()` | `;` (Win) or `:` (Unix) |
+| `findExecutable(name)` | Cross-platform executable lookup |
+| `requiresShell(command)` | `.cmd/.bat` shell detection (Win) |

-**4. Path Handling Best Practices**
+Never hardcode paths. Use `findExecutable()` and `joinPaths()`. See [ARCHITECTURE.md](shared_docs/ARCHITECTURE.md#cross-platform-development) for extended guide.

-```typescript
-// ❌ WRONG - Hardcoded Windows path
-const claudePath = 'C:\\Program Files\\Claude\\claude.exe';
+## E2E Testing (Electron MCP)

-// ❌ WRONG - Hardcoded macOS path
-const brewPath = '/opt/homebrew/bin/python3';
+QA agents can interact with the running Electron app via Chrome DevTools Protocol:

-// ❌ WRONG - Manual path joining
-const fullPath = dir + '/subdir/file.txt';
+1. Start app: `npm run dev:debug` (debug mode for AI self-validation via Electron MCP)
+2. Set `ELECTRON_MCP_ENABLED=true` in `apps/backend/.env`
+3. Run QA: `python run.py --spec 001 --qa`

-// ✅ CORRECT - Use platform abstraction
-import { findExecutable, joinPaths } from './platform';
-
-const claudePath = await findExecutable('claude');
-const fullPath = joinPaths(dir, 'subdir', 'file.txt');
-```
-
-**5. Testing Platform-Specific Code**
-
-```typescript
-// Mock process.platform for testing
-import { isWindows } from './platform';
-
-// In tests, use jest.mock or similar
-jest.mock('./platform', () => ({
-  isWindows: () => true  // Simulate Windows
-}));
-```
-
-**6. When You Need Platform-Specific Code**
-
-If you must write platform-specific code:
-
-1. **Add it to the platform module** - Not scattered in your feature code
-2. **Write tests for all platforms** - Mock `process.platform` to test each case
-3. **Use feature detection** - Check for file/path existence, not just OS name
-4. **Document why** - Explain the platform difference in comments
-
-**7. Submitting Platform-Specific Fixes**
-
-When fixing a platform-specific bug:
-
-1. Ensure your fix doesn't break other platforms
-2. Test locally if you have access to other OSs
-3. Rely on CI to catch issues you can't test
-4. Consider adding a test that mocks other platforms
-
-**Example: Adding a New Tool Detection**
-
-```typescript
-// ✅ CORRECT - Add to platform/paths.ts
-export function getMyToolPaths(): string[] {
-  if (isWindows()) {
-    return [
-      joinPaths('C:', 'Program Files', 'MyTool', 'tool.exe'),
-      // ... more Windows paths
-    ];
-  }
-  return [
-    joinPaths('/usr', 'local', 'bin', 'mytool'),
-    // ... more Unix paths
-  ];
-}
-
-// ✅ CORRECT - Use in your code
-import { findExecutable, getMyToolPaths } from './platform';
-
-const toolPath = await findExecutable('mytool', getMyToolPaths());
-```
-
-### End-to-End Testing (Electron App)
-
-**IMPORTANT: When bug fixing or implementing new features in the frontend, AI agents can perform automated E2E testing using the Electron MCP server.**
-
-The Electron MCP server allows QA agents to interact with the running Electron app via Chrome DevTools Protocol:
-
-**Setup:**
-1. Start the Electron app with remote debugging enabled:
-   ```bash
-   npm run dev  # Already configured with --remote-debugging-port=9222
-   ```
-
-2. Enable Electron MCP in `apps/backend/.env`:
-   ```bash
-   ELECTRON_MCP_ENABLED=true
-   ELECTRON_DEBUG_PORT=9222  # Default port
-   ```
-
-**Available Testing Capabilities:**
-
-QA agents (`qa_reviewer` and `qa_fixer`) automatically get access to Electron MCP tools:
-
-1. **Window Management**
-   - `mcp__electron__get_electron_window_info` - Get info about running windows
-   - `mcp__electron__take_screenshot` - Capture screenshots for visual verification
-
-2. **UI Interaction**
-   - `mcp__electron__send_command_to_electron` with commands:
-     - `click_by_text` - Click buttons/links by visible text
-     - `click_by_selector` - Click elements by CSS selector
-     - `fill_input` - Fill form fields by placeholder or selector
-     - `select_option` - Select dropdown options
-     - `send_keyboard_shortcut` - Send keyboard shortcuts (Enter, Ctrl+N, etc.)
-     - `navigate_to_hash` - Navigate to hash routes (#settings, #create, etc.)
-
-3. **Page Inspection**
-   - `get_page_structure` - Get organized overview of page elements
-   - `debug_elements` - Get debugging info about buttons and forms
-   - `verify_form_state` - Check form state and validation
-   - `eval` - Execute custom JavaScript code
-
-4. **Logging**
-   - `mcp__electron__read_electron_logs` - Read console logs for debugging
-
-**Example E2E Test Flow:**
-
-```python
-# 1. Agent takes screenshot to see current state
-agent: "Take a screenshot to see the current UI"
-# Uses: mcp__electron__take_screenshot
-
-# 2. Agent inspects page structure
-agent: "Get page structure to find available buttons"
-# Uses: mcp__electron__send_command_to_electron (command: "get_page_structure")
-
-# 3. Agent clicks a button to navigate
-agent: "Click the 'Create New Spec' button"
-# Uses: mcp__electron__send_command_to_electron (command: "click_by_text", args: {text: "Create New Spec"})
-
-# 4. Agent fills out a form
-agent: "Fill the task description field"
-# Uses: mcp__electron__send_command_to_electron (command: "fill_input", args: {placeholder: "Describe your task", value: "Add login feature"})
-
-# 5. Agent submits and verifies
-agent: "Click Submit and verify success"
-# Uses: click_by_text → take_screenshot → verify result
-```
-
-**When to Use E2E Testing:**
-
- **Bug Fixes**: Reproduce the bug, apply fix, verify it's resolved
- **New Features**: Implement feature, test the UI flow end-to-end
- **UI Changes**: Verify visual changes and interactions work correctly
- **Form Validation**: Test form submission, validation, error handling
-
-**Configuration in `core/client.py`:**
-
-The client automatically enables Electron MCP tools for QA agents when:
- Project is detected as Electron (`is_electron` capability)
- `ELECTRON_MCP_ENABLED=true` is set
- Agent type is `qa_reviewer` or `qa_fixer`
-
-**Note:** Screenshots are automatically compressed (1280x720, quality 60, JPEG) to stay under Claude SDK's 1MB JSON message buffer limit.
+Tools: `take_screenshot`, `click_by_text`, `fill_input`, `get_page_structure`, `send_keyboard_shortcut`, `eval`. See [ARCHITECTURE.md](shared_docs/ARCHITECTURE.md#end-to-end-testing) for full capabilities.

 The project consists of two main components:

 1. **Python Backend** (`apps/backend/`) - The core autonomous coding framework
-2. **Electron Frontend** (`apps/frontend/`) - Optional desktop UI
+2. **Electron Frontend** (`apps/frontend/`) - Desktop UI

-### Python Backend
-
-The recommended way is to use `npm run install:backend` (or `npm run install:all` from the root), which automatically installs both runtime and test dependencies. You can also set up manually:
+From the repository root, two commands handle everything:

 ```bash
-# Navigate to the backend directory
-cd apps/backend
+# Install all dependencies (Python backend + Electron frontend)
+npm run install:all

-# Create virtual environment
-# Windows:
-py -3.12 -m venv .venv
-.venv\Scripts\activate
-
-# macOS/Linux:
-python3.12 -m venv .venv
-source .venv/bin/activate
-
-# Install dependencies
-pip install -r requirements.txt
-
-# Install test dependencies
-pip install -r ../../tests/requirements-test.txt
-
-# Set up environment
-cp .env.example .env
-# Edit .env and add your CLAUDE_CODE_OAUTH_TOKEN (get it via: claude setup-token)
-```
-
-### Electron Frontend
-
-```bash
-# Navigate to the frontend directory
-cd apps/frontend
-
-# Install dependencies
-npm install
-
-# Start development server
+# Start development mode (hot reload)
 npm run dev
-
-# Build for production
-npm run build
-
-# Package for distribution
-npm run package
 ```

-## Running from Source
-
-If you want to run Auto Claude from source (for development or testing unreleased features), follow these steps:
-
-### Step 1: Clone and Set Up
+`npm run install:all` automatically:
+- Detects Python 3.12+ on your system
+- Creates a virtual environment (`apps/backend/.venv`)
+- Installs backend runtime and test dependencies
+- Copies `.env.example` to `.env` (if not already present)
+- Installs frontend npm dependencies

+After install, configure your credentials in `apps/backend/.env`:
 ```bash
-git clone https://github.com/AndyMik90/Auto-Claude.git
-cd Auto-Claude/apps/backend
+# Get your Claude Code OAuth token
+claude setup-token

-# Using uv (recommended)
-uv venv && uv pip install -r requirements.txt
-
-# Or using standard Python
-python3 -m venv .venv
-source .venv/bin/activate  # On Windows: .venv\Scripts\activate
-pip install -r requirements.txt
-
-# Set up environment
-cd apps/backend
-cp .env.example .env
-# Edit .env and add your CLAUDE_CODE_OAUTH_TOKEN (get it via: claude setup-token)
+# Then edit apps/backend/.env with your token and any other provider keys
 ```

-### Step 2: Run the Desktop UI
+### Other Useful Commands

 ```bash
-cd ../frontend
-
-# Install dependencies
-npm install
-
-# Development mode (hot reload)
-npm run dev
-
-# Or production build
-npm run build && npm run start
+npm start              # Build and run production
+npm run build          # Build frontend for production
+npm run package        # Package for distribution
+npm run test:backend   # Run Python tests
 ```

-# Token Encryption Investigation
-
-## Issue Summary
-
-Auto-Claude users are experiencing API 401 errors ("Invalid bearer token") because the Python backend is passing encrypted tokens (with `enc:` prefix) directly to the Claude Agent SDK without decryption. Standalone Claude Code terminals work correctly because they decrypt these tokens before use.
-
-**Key insight from user thehaffk:** "python cant unencrypt claude token and it launches session with CLAUDE_CODE_OAUTH_TOKEN=enc:djEwtxMGISt3tQ..."
-
-## Token Storage Format
-
-### Encrypted Token Format
-
-Claude Code CLI stores OAuth tokens in an encrypted format with the prefix `enc:`:
-
-```text
-enc:djEwtxMGISt3tQ...
-```
-
-This format is used when tokens are stored in:
- **macOS**: Keychain (service: "Claude Code-credentials")
- **Linux**: Secret Service API (DBus, via secretstorage library)
- **Windows**: Credential Manager / .credentials.json files
-
-### Decrypted Token Format
-
-Valid Claude OAuth tokens have the format:
-```text
-sk-ant-oat01-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
-```
-
-## Current Token Flow (BROKEN)
-
-1. **Token Storage**: Claude Code CLI stores encrypted token with `enc:` prefix in system keychain
-2. **Token Retrieval**: `apps/backend/core/auth.py::get_auth_token()` retrieves token from:
-   - Environment variable `CLAUDE_CODE_OAUTH_TOKEN`
-   - OR system keychain via `get_token_from_keychain()`
-3. **❌ NO DECRYPTION**: Token is returned as-is with `enc:` prefix intact
-4. **SDK Initialization**: Encrypted token passed to Claude Agent SDK
-5. **API Call Fails**: SDK sends encrypted token to API → 401 error
-
-### Proof of Broken Flow
-
-Test in `apps/backend`:
-```python
-import os
-os.environ['CLAUDE_CODE_OAUTH_TOKEN'] = 'enc:test123'
-
-from core.auth import get_auth_token
-token = get_auth_token()
-print(f"Token: {token}")  # Output: "enc:test123"
-print(f"Encrypted: {token.startswith('enc:')}")  # Output: True
-```
-
-## How Standalone Claude Code CLI Handles Tokens
-
-### Current Understanding
-
-1. **Token Detection**: CLI checks if token starts with `enc:` prefix
-2. **Decryption**: If encrypted, CLI decrypts using platform-specific keyring access
-3. **Authentication**: Decrypted `sk-ant-oat01-` token is used for API calls
-
-### Missing Documentation
-
-Web search for "Claude Code CLI encrypted token enc: prefix decryption" found:
- Token storage formats (JSON with accessToken, refreshToken, expiresAt)
- Security issues (tokens exposed in debug logs before v2.1.0)
- Keychain access patterns for macOS/Linux/Windows
-
-**❌ NOT FOUND**: Specific documentation on how Claude Code CLI decrypts `enc:` tokens
-
-Sources:

-
-## Decryption Approach Options
-
-### Option 1: Claude Agent SDK Built-in Decryption
-
-**Status**: NEEDS VERIFICATION
-
-The Claude Agent SDK (`claude-agent-sdk>=0.1.19`) may handle decryption internally if:
- Token is passed to SDK still encrypted
- SDK detects `enc:` prefix
- SDK has access to system keyring for decryption
-
-**Action Required**: Check if SDK has decryption capabilities by examining:
- SDK source code or documentation
- Whether SDK expects encrypted vs decrypted tokens
- If SDK requires specific environment variables for decryption
-
-### Option 2: Python Backend Decryption (Recommended)
-
-**Approach**: Implement decryption in `apps/backend/core/auth.py` before passing to SDK
-
-**Implementation Pattern**:
-```python
-def get_auth_token() -> str | None:
-    """Get authentication token (decrypted if necessary)."""
-    token = _retrieve_token_from_sources()  # From env or keychain
-
-    if token and token.startswith("enc:"):
-        # Decrypt the token
-        token = decrypt_token(token)
-
-    return token
-
-def decrypt_token(encrypted_token: str) -> str:
-    """
-    Decrypt Claude Code encrypted token.
-
-    Args:
-        encrypted_token: Token with 'enc:' prefix
-
-    Returns:
-        Decrypted token in format 'sk-ant-oat01-...'
-    """
-    # Remove 'enc:' prefix
-    encrypted_data = encrypted_token[4:]
-
-    # TODO: Implement decryption logic
-    # Questions to answer:
-    # 1. What encryption algorithm does Claude Code use?
-    # 2. Where is the decryption key stored?
-    # 3. Is the decryption key platform-specific (per-user)?
-    # 4. Can we reuse Claude Code's decryption mechanism?
-
-    raise NotImplementedError("Token decryption not yet implemented")
-```
-
-### Option 3: Call Claude Code CLI for Decryption
-
-**Approach**: Use the Claude Code CLI binary to decrypt tokens
-
-```python
-def decrypt_token(encrypted_token: str) -> str:
-    """Decrypt token by invoking Claude Code CLI."""
-    # Find claude binary
-    claude_path = shutil.which("claude") or "~/.local/bin/claude"
-
-    # Use CLI command to get decrypted token
-    # (if such a command exists - needs research)
-    result = subprocess.run(
-        [claude_path, "auth", "decrypt", encrypted_token],
-        capture_output=True,
-        text=True
-    )
-
-    return result.stdout.strip()
-```
-
-**Issues**:
- Requires Claude Code CLI to be installed
- No documented CLI command for token decryption
- Adds external dependency
-
-## Required Investigation Steps
-
-### 1. Verify SDK Decryption Capabilities
-
-**Task**: Check if `claude-agent-sdk` handles `enc:` tokens automatically
-
-**Method**:
-```bash
-# In environment with SDK installed
-python3 << 'EOF'
-import os
-os.environ['CLAUDE_CODE_OAUTH_TOKEN'] = 'enc:...'  # Real encrypted token
-
-from claude_agent_sdk import Client
-# Try creating client - does it decrypt internally?
-client = Client()
-# Check if authentication works
-EOF
-```
-
-### 2. Reverse Engineer Claude Code CLI Decryption
-
-**Task**: Understand how Claude CLI decrypts tokens
-
-**Method**:
- Examine Claude CLI binary (if possible)
- Trace system calls when CLI runs (strace on Linux, dtruss on macOS)
- Check if CLI accesses specific keychain entries for decryption keys
- Look for encryption/decryption libraries used by CLI
-
-### 3. Find Decryption Key Storage
-
-**Task**: Locate where decryption keys are stored
-
-**Hypothesis**: Decryption key stored in:
- macOS: Keychain (separate entry from encrypted token)
- Linux: Secret Service API
- Windows: Credential Manager
-
-**Verification**:
-```bash
-# macOS: List all keychain entries
-security find-generic-password -a "$(whoami)" | grep -i claude
-
-# Linux: Use secretstorage to list all items
-python3 -c "import secretstorage; ..."
-```
-
-## Recommended Decryption Approach for Python Backend
-
-Based on investigation so far, the recommended approach is:
-
-1. **Detect encrypted tokens**: Check for `enc:` prefix in `get_auth_token()`
-2. **Decrypt before use**: Implement `decrypt_token()` function
-3. **Platform-specific decryption**: Use appropriate keyring library:
-   - macOS: Use `subprocess` with `/usr/bin/security` to access decryption key
-   - Linux: Use `secretstorage` library to access Secret Service API
-   - Windows: Access Credential Manager or credentials.json
-4. **Backward compatibility**: Support both encrypted and plaintext tokens
-5. **Error handling**: Provide clear error messages if decryption fails
-
-## Complete Token Flow Trace (Frontend → Backend)
-
-### 1. Token Retrieval (Frontend)
-
-**File**: `apps/frontend/src/main/services/profile-service.ts`
-
-The frontend retrieves the OAuth token from the system keychain but **does not decrypt it**. When no API profile is active (OAuth mode), the frontend returns an empty environment object, which means it relies on:
- The token already being in the environment as `CLAUDE_CODE_OAUTH_TOKEN`
- OR the Python backend retrieving it from the keychain
-
-**Key Code**:
-```typescript
-// Line 223: Returns empty object in OAuth mode, allowing
-// CLAUDE_CODE_OAUTH_TOKEN to be used from system keychain
-```
-
-### 2. Environment Variable Passing (Frontend → PTY)
-
-**File**: `apps/frontend/src/main/terminal/pty-manager.ts`
-
-The PTY manager spawns the terminal shell with environment variables, including `CLAUDE_CODE_OAUTH_TOKEN`:
-
-**Key Code** (Lines 149-152):
-```typescript
-// Remove ANTHROPIC_API_KEY to ensure Claude Code uses OAuth tokens
-// (CLAUDE_CODE_OAUTH_TOKEN from profileEnv) instead of API keys
-const { DEBUG: _DEBUG, ANTHROPIC_API_KEY: _ANTHROPIC_API_KEY, ...cleanEnv } = process.env;
-```
-
-**Important**: The frontend passes through whatever token value exists in the environment - it does NOT check for `enc:` prefix or decrypt it.
-
-### 3. Token Retrieval (Backend)
-
-**File**: `apps/backend/core/auth.py`
-
-#### 3.1. get_auth_token()
-
-This function retrieves the token from multiple sources:
-
-```python
-def get_auth_token() -> str | None:
-    # First check environment variables
-    for var in AUTH_TOKEN_ENV_VARS:  # CLAUDE_CODE_OAUTH_TOKEN, ANTHROPIC_AUTH_TOKEN
-        token = os.environ.get(var)
-        if token:
-            return token  # ❌ Returns immediately without checking for enc: prefix
-
-    # Fallback to system credential store
-    return get_token_from_keychain()  # ❌ Also returns without decryption
-```
-
-**Issue**: Returns token as-is with `enc:` prefix intact.
-
-#### 3.2. require_auth_token()
-
-This function calls `get_auth_token()` and raises an error if no token is found:
-
-```python
-def require_auth_token() -> str:
-    token = get_auth_token()  # ❌ Gets encrypted token
-    if not token:
-        raise ValueError("No OAuth token found...")
-    return token  # ❌ Returns encrypted token
-```
-
-**Issue**: No decryption step between retrieval and return.
-
-#### 3.3. ensure_claude_code_oauth_token()
-
-This function ensures the environment variable is set:
-
-```python
-def ensure_claude_code_oauth_token() -> None:
-    if os.environ.get("CLAUDE_CODE_OAUTH_TOKEN"):
-        return
-
-    token = get_auth_token()  # ❌ Gets encrypted token
-    if token:
-        os.environ["CLAUDE_CODE_OAUTH_TOKEN"] = token  # ❌ Sets encrypted token
-```
-
-**Issue**: Propagates encrypted token to environment variable.
-
-### 4. Token Usage in SDK Client Creation (Backend)
-
-#### 4.1. Full Client Creation
-
-**File**: `apps/backend/core/client.py` (see `create_client()` function)
-
-```python
-def create_client(...):
-    oauth_token = require_auth_token()  # ❌ Gets encrypted token
-    # Ensure SDK can access it via its expected env var
-    os.environ["CLAUDE_CODE_OAUTH_TOKEN"] = oauth_token  # ❌ Sets encrypted token
-```
-
-**Issue**: Encrypted token is passed to the Claude Agent SDK, which expects a decrypted `sk-ant-oat01-` token.
-
-#### 4.2. Simple Client Creation
-
-**File**: `apps/backend/core/simple_client.py` (see `create_simple_client()` function)
-
-```python
-def create_simple_client(...):
-    # Get authentication
-    oauth_token = require_auth_token()  # ❌ Gets encrypted token
-    import os
-    os.environ["CLAUDE_CODE_OAUTH_TOKEN"] = oauth_token  # ❌ Sets encrypted token
-```
-
-**Issue**: Same problem - encrypted token passed to SDK.
-
-#### 4.3. Other Usages
-
-**Files**:
- `apps/backend/core/workspace.py` (Line 1966) - AI merge operations
- `apps/backend/runners/insights_runner.py` - Insights analysis
- `apps/backend/runners/github/batch_issues.py` - GitHub batch operations
- `apps/backend/integrations/linear/updater.py` - Linear integration
- `apps/backend/commit_message.py` - Commit message generation
- `apps/backend/analysis/insight_extractor.py` - Code insights
- `apps/backend/merge/ai_resolver/claude_client.py` - Merge resolution
-
-**All follow the same pattern**: Call `ensure_claude_code_oauth_token()` → encrypted token in environment → SDK receives encrypted token → API 401 error.
-
-### 5. Where Decryption Should Be Inserted
-
-Based on the flow analysis, decryption should be added at **the earliest point of token retrieval** to avoid duplicating decryption logic:
-
-**RECOMMENDED INSERTION POINT**: `apps/backend/core/auth.py::get_auth_token()`
-
-```python
-def get_auth_token() -> str | None:
-    # First check environment variables
-    for var in AUTH_TOKEN_ENV_VARS:
-        token = os.environ.get(var)
-        if token:
-            # ✅ INSERT DECRYPTION HERE
-            if token.startswith("enc:"):
-                token = decrypt_token(token)
-            return token
-
-    # Fallback to system credential store
-    token = get_token_from_keychain()
-    # ✅ ALSO DECRYPT KEYCHAIN TOKENS
-    if token and token.startswith("enc:"):
-        token = decrypt_token(token)
-    return token
-```
-
-**Benefits of this approach**:
-1. Single location for decryption logic
-2. All downstream functions automatically get decrypted tokens
-3. Backward compatible (plaintext tokens pass through unchanged)
-4. Consistent behavior across all token sources (env vars and keychain)
-
-**Alternative insertion points** (NOT recommended):
- `require_auth_token()` - Would need similar logic in `get_auth_token()` for non-required usage
- `create_client()` - Would need duplication in `create_simple_client()` and all other clients
- `ensure_claude_code_oauth_token()` - Would miss direct `get_auth_token()` calls
-
-## Next Steps
-
-1. ✅ Document current token flow and identify issue (THIS FILE - COMPLETED)
-2. ✅ Trace token flow from frontend to backend (THIS FILE - COMPLETED)
-3. ✅ Identify where decryption should be inserted (THIS FILE - COMPLETED)
-4. ⏳ Verify if Claude Agent SDK handles decryption internally
-5. ⏳ Reverse engineer or document Claude Code CLI decryption mechanism
-6. ⏳ Implement `decrypt_token()` function in `apps/backend/core/auth.py`
-7. ⏳ Add encryption detection and auto-decryption to `get_auth_token()`
-8. ⏳ Test with real encrypted tokens on macOS and Linux
-9. ⏳ Add comprehensive error handling for decryption failures
-
-## Open Questions
-
-1. **What encryption algorithm does Claude Code use for `enc:` tokens?**
-   - Possible: AES-256, ChaCha20, or similar
-   - Key derivation method?
-
-2. **Where is the decryption key stored?**
-   - Same keychain entry as encrypted token?
-   - Separate keychain entry?
-   - Derived from system/user credentials?
-
-3. **Does Claude Agent SDK expect encrypted or decrypted tokens?**
-   - If it expects decrypted: we must decrypt before passing
-   - If it handles encryption: we may be missing SDK configuration
-
-4. **Is there a Claude Code CLI command to decrypt tokens?**
-   - `claude auth decrypt <token>`?
-   - `claude auth get-token`?
-   - No documented command found in research
-
-5. **Can we reuse Claude Code's decryption mechanism?**
-   - Import decryption functions from CLI?
-   - Call CLI as subprocess?
-   - Implement decryption ourselves?

+
+IMPORTANT: Be accurate and honest about what has and hasn't been verified.
+
+**Check these based on context (you can infer from the diff/spec):**
+- Base Branch targeting — check based on target_branch value
+- Type of Change (bug fix, feature, docs, refactor, test) — infer from diff and spec
+- Area (Frontend, Backend, Fullstack) — infer from changed file paths
+- Feature Toggle "N/A" — if the feature appears complete and not behind a flag
+- Breaking Changes "No" — if changes appear backward compatible
+
+**Leave UNCHECKED (these require human verification you cannot perform):**
+- "I've tested my changes locally" — you have not tested anything
+- "All CI checks pass" — CI has not run yet
+- "Windows/macOS/Linux tested" — requires manual testing on each platform
+- "All existing tests pass" — CI has not run yet
+- "New features include test coverage" — unless test files are clearly visible in the diff
+- "Bug fixes include regression tests" — unless test files are clearly visible in the diff
+
+**For platform/code quality checkboxes:**
+- "Used centralized platform/ module" — leave unchecked unless you can verify from the diff
+- "No hardcoded paths" — leave unchecked unless you can verify from the diff
+- "PR is small and focused (< 400 lines)" — check only if diff stats show < 400 lines changed
+
+**For the "I've synced with develop branch" checkbox:**
+- Leave unchecked — you cannot verify the sync status

+
+If your environment shows **"Isolation Mode: WORKTREE"**, you are working in an **isolated git worktree**.
+This is a complete copy of the project created for safe, isolated development.
+
+### Critical Rules for Worktree Mode:
+
+1. **NEVER navigate to the parent project path** shown in "FORBIDDEN PATH"

+   - The parent project is OFF LIMITS

+
+3. **Git commits in the wrong location = disaster**
+   - Commits made after escaping go to the WRONG branch
+   - This defeats the entire isolation system
+
+### Why You Might Be Tempted to Escape:
+
+You may see absolute paths like `/e/projects/myapp/prod/src/file.ts` in:
+- `spec.md` (file references)
+- `context.json` (discovered files)
+- Error messages
+
+**DO NOT** `cd` to these paths. Instead, convert them to relative paths:
+- `/e/projects/myapp/prod/src/file.ts` → `./prod/src/file.ts`

+# PR Review System Quality Control Prompt
+
+You are a senior software architect tasked with quality-controlling an AI-powered PR review system. Your goal is to analyze the system holistically, identify gaps between intent and implementation, and provide actionable feedback.
+
+## System Overview
+
+This is a **parallel orchestrator PR review system** that:
+1. An orchestrator AI analyzes a PR and delegates to specialist agents
+2. Specialist agents (security, quality, logic, codebase-fit) perform deep reviews
+3. A finding-validator agent validates all findings against actual code
+4. The orchestrator synthesizes results into a final verdict
+
+**Key Design Principles (from vision document):**
+- Evidence-based validation (NOT confidence-based)
+- Pattern-triggered mandatory exploration (6 semantic triggers)
+- Understand intent BEFORE looking for issues
+- The diff is the question, not the answer
+
+---
+
+## FILES TO EXAMINE
+
+### Vision & Architecture
+- `docs/PR_REVIEW_99_TRUST.md` - The vision document defining 99% trust goal
+
+### Orchestrator Prompts

+
+## ANALYSIS TASKS
+
+### 1. Vision Alignment Check
+Compare the implementation against `PR_REVIEW_99_TRUST.md`:
+
+- [ ] **Evidence-based validation**: Is the system truly evidence-based or does it still use confidence scores anywhere?
+- [ ] **6 Mandatory Triggers**: Are all 6 semantic triggers properly defined and enforced?
+  1. Output contract changed
+  2. Input contract changed
+  3. Behavioral contract changed
+  4. Side effect contract changed
+  5. Failure contract changed
+  6. Null/undefined contract changed
+- [ ] **Phase 0 (Understand Intent)**: Is it mandatory? Is it enforced before delegation?
+- [ ] **Phase 1 (Trigger Detection)**: Is it mandatory? Does it output explicit trigger analysis?
+- [ ] **Bounded Exploration**: Is exploration limited to depth 1 (direct callers only)?
+
+### 2. Prompt Quality Analysis
+For each agent prompt, check:
+
+- [ ] Does it explain WHAT to look for?
+- [ ] Does it explain HOW to verify findings?
+- [ ] Does it require evidence (code snippets, line numbers)?
+- [ ] Does it define when to STOP exploring?
+- [ ] Does it distinguish between "in scope" and "out of scope"?
+- [ ] Does it handle the "no issues found" case properly?
+
+### 3. Schema Enforcement
+Check `pydantic_models.py`:
+
+- [ ] Is `VerificationEvidence` required (not optional) on all finding types?
+- [ ] Does `VerificationEvidence` require:
+  - `code_examined` (actual code, not description)
+  - `line_range_examined` (specific lines)
+  - `verification_method` (how it was verified)
+- [ ] Are there any finding types that bypass evidence requirements?
+
+### 4. Information Flow
+Trace how information flows:
+
+- [ ] PR Context → Orchestrator: What context is provided?
+- [ ] Orchestrator → Specialists: Are triggers passed? Are known callers passed?
+- [ ] Specialists → Validator: Are all findings validated?
+- [ ] Validator → Final Output: Are false positives properly dismissed?
+
+### 5. False Positive Prevention
+Check mechanisms to prevent false positives:
+
+- [ ] Do specialists verify issues exist before reporting?
+- [ ] Does the validator re-read the actual code?
+- [ ] Are "missing X" claims (missing error handling, etc.) verified?
+- [ ] Are dismissed findings tracked for transparency?
+
+### 6. Log Analysis (ATTACH LOGS BELOW)
+When reviewing logs, check:
+
+- [ ] Did the orchestrator output PR UNDERSTANDING before delegating?
+- [ ] Did the orchestrator output TRIGGER DETECTION before delegating?
+- [ ] Were triggers passed to specialists in delegation prompts?
+- [ ] Did specialists actually explore when triggers were present?
+- [ ] Were findings validated with real code evidence?
+- [ ] Were any false positives caught by the validator?
+
+---
+
+## SPECIFIC QUESTIONS TO ANSWER
+
+1. **Trigger System Effectiveness**: Did the trigger detection system correctly identify semantic contract changes? Were there any missed triggers or false triggers?
+
+2. **Exploration Quality**: When exploration was mandated by a trigger, did specialists explore effectively? Did they stop at the right time?
+
+3. **Evidence Quality**: Are the `code_examined` fields in findings actual code snippets or just descriptions? Are line numbers accurate?
+
+4. **False Positive Rate**: How many findings were dismissed as false positives? What caused them?
+
+5. **Missing Issues**: Based on your understanding of the PR, were there any issues that SHOULD have been caught but weren't?
+
+6. **Prompt Gaps**: Are there any scenarios not covered by the current prompts?
+
+7. **Schema Gaps**: Are there any ways findings could bypass evidence requirements?

+- Prioritize issues that cause **false positives** (annoying) over false negatives (missed issues)
+- Consider **language-agnostic** design - the system should work for any codebase
+- Think about **edge cases**: empty PRs, huge PRs, refactor-only PRs, CSS-only PRs
+- The goal is **99% trust** - developers should trust the review enough to act on it immediately

 Ensure new code integrates well with the existing codebase. Check for consistency with project conventions, reuse of existing utilities, and architectural alignment. Focus ONLY on codebase fit - not security, logic correctness, or general quality.

+## Phase 1: Understand the PR Intent (BEFORE Looking for Issues)
+
+**MANDATORY** - Before searching for issues, understand what this PR is trying to accomplish.
+
+1. **Read the provided context**
+   - PR description: What does the author say this does?
+   - Changed files: What areas of code are affected?
+   - Commits: How did the PR evolve?
+
+2. **Identify the change type**
+   - Bug fix: Correcting broken behavior
+   - New feature: Adding new capability
+   - Refactor: Restructuring without behavior change
+   - Performance: Optimizing existing code
+   - Cleanup: Removing dead code or improving organization
+
+3. **State your understanding** (include in your analysis)
+   ```
+   PR INTENT: This PR [verb] [what] by [how].
+   RISK AREAS: [what could go wrong specific to this change type]
+   ```
+
+**Only AFTER completing Phase 1, proceed to looking for issues.**
+
+Why this matters: Understanding intent prevents flagging intentional design decisions as bugs.
+
+## TRIGGER-DRIVEN EXPLORATION (CHECK YOUR DELEGATION PROMPT)
+
+**FIRST**: Check if your delegation prompt contains a `TRIGGER:` instruction.
+
+- **If TRIGGER is present** → Exploration is **MANDATORY**, even if the diff looks correct
+- **If no TRIGGER** → Use your judgment to explore or not
+
+### How to Explore (Bounded)
+
+1. **Read the trigger** - What pattern did the orchestrator identify?
+2. **Form the specific question** - "Do similar functions elsewhere follow the same pattern?" (not "what's in the codebase?")
+3. **Use Grep** to find similar patterns, usages, or implementations
+4. **Use Read** to examine 3-5 relevant files
+5. **Answer the question** - Yes (report issue) or No (move on)
+6. **Stop** - Do not explore beyond the immediate question
+
+### Codebase-Fit-Specific Trigger Questions
+
+| Trigger | Codebase Fit Question to Answer |
+|---------|--------------------------------|
+| **Output contract changed** | Do other similar functions return the same type/structure? |
+| **Input contract changed** | Is this parameter change consistent with similar functions? |
+| **New pattern introduced** | Does this pattern already exist elsewhere that should be reused? |
+| **Naming changed** | Is the new naming consistent with project conventions? |
+| **Architecture changed** | Does this architectural change align with existing patterns? |
+
+### Example Exploration
+
+```
+TRIGGER: New pattern introduced (custom date formatter)
+QUESTION: Does a date formatting utility already exist?
+
+1. Grep for "formatDate\|dateFormat\|toDateString" → found utils/date.ts
+2. Read utils/date.ts → exports formatDate(date, format) with same functionality
+3. STOP - Found existing utility
+
+FINDINGS:
+- src/components/Report.tsx:45 - Implements custom date formatting
+  Existing utility: utils/date.ts exports formatDate() with same functionality
+  Suggestion: Use existing formatDate() instead of duplicating logic
+```
+
+### When NO Trigger is Given
+
+If the orchestrator doesn't specify a trigger, use your judgment:
+- Focus on pattern consistency in the changed code
+- Search for existing utilities that could be reused
+- Don't explore "just to be thorough"

+## Valid Outputs
+
+Finding issues is NOT the goal. Accurate review is the goal.
+
+### Valid: No Significant Issues Found
+If the code is well-implemented, say so:
+```json
+{
+  "findings": [],
+  "summary": "Reviewed [files]. No codebase_fit issues found. The implementation correctly [positive observation about the code]."
+}
+```
+
+### Valid: Only Low-Severity Suggestions
+Minor improvements that don't block merge:
+```json
+{
+  "findings": [
+    {"severity": "low", "title": "Consider extracting magic number to constant", ...}
+  ],
+  "summary": "Code is sound. One minor suggestion for readability."
+}
+```
+
+### INVALID: Forced Issues
+Do NOT report issues just to have something to say:
+- Theoretical edge cases without evidence they're reachable
+- Style preferences not backed by project conventions
+- "Could be improved" without concrete problem
+- Pre-existing issues not introduced by this PR
+
+**Reporting nothing is better than reporting noise.** False positives erode trust faster than false negatives.

 4. **PROVIDE** concrete code evidence - the actual code that proves or disproves the issue
 5. **RETURN** validation status with evidence (binary decision based on what the code shows)

+## Batch Processing (Multiple Findings)
+
+You may receive multiple findings to validate at once. When processing batches:
+
+1. **Group by file** - Read each file once, validate all findings in that file together
+2. **Process systematically** - Validate each finding in order, don't skip any
+3. **Return all results** - Your response must include a validation result for EVERY finding received
+4. **Optimize reads** - If 3 findings are in the same file, read it once with enough context for all

+**Expected output:** 3 separate validation results, one for each finding ID.
+
+## Hypothesis-Validation Structure (MANDATORY)
+
+For EACH finding you investigate, use this structured approach. This prevents rubber-stamping findings as valid without actually verifying them.
+
+### Step 1: State the Hypothesis
+
+Before reading any code, clearly state what you're testing:
+
+```
+HYPOTHESIS: The finding claims "{title}" at {file}:{line}
+
+This hypothesis is TRUE if:
+1. The code at {line} contains the specific pattern described
+2. No mitigation exists in surrounding context (+/- 20 lines)
+3. The issue is actually reachable/exploitable in this codebase
+
+This hypothesis is FALSE if:
+1. The code at {line} is different than described
+2. Mitigation exists (validation, sanitization, framework protection)
+3. The code is unreachable or purely theoretical
+```
+
+### Step 2: Gather Evidence
+
+Read the actual code. Copy-paste it into `code_evidence`.
+
+```
+FILE: {file}
+LINES: {line-20} to {line+20}
+ACTUAL CODE:
+[paste the code here - this is your proof]
+```
+
+### Step 3: Test Each Condition
+
+For each condition in your hypothesis:
+
+```
+CONDITION 1: Code contains {specific pattern from finding}
+EVIDENCE: [specific line from code_evidence that proves/disproves]
+RESULT: TRUE / FALSE / INCONCLUSIVE
+
+CONDITION 2: No mitigation in surrounding context
+EVIDENCE: [what you found or didn't find in ±20 lines]
+RESULT: TRUE / FALSE / INCONCLUSIVE
+
+CONDITION 3: Issue is reachable/exploitable
+EVIDENCE: [how input reaches this code, or why it doesn't]
+RESULT: TRUE / FALSE / INCONCLUSIVE
+```
+
+### Step 4: Conclude Based on Evidence
+
+Apply these rules strictly:
+
+| Conditions | Conclusion |
+|------------|------------|
+| ALL conditions TRUE | `confirmed_valid` |
+| ANY condition FALSE | `dismissed_false_positive` |
+| ANY condition INCONCLUSIVE, none FALSE | `needs_human_review` |

+Testing conditions:
+CONDITION 1: User input in SQL string
+EVIDENCE: Line 45 uses f-string interpolation: f"SELECT * FROM users WHERE id = {user_id}"

+CONDITION 2: No sanitization
+EVIDENCE: No validation between request.args["id"] (line 43) and query construction (line 45)
+RESULT: TRUE

+CONDITION 3: Input reachable
+EVIDENCE: Comment says "user_id comes from request.args", confirmed by caller on line 12

+CONCLUSION: confirmed_valid (all conditions TRUE)
+CODE_EVIDENCE: "query = f\"SELECT * FROM users WHERE id = {user_id}\""

+### Duplication Findings ("code is duplicated 3 times")
+
+**Before confirming a duplication finding, you MUST:**
+
+1. **Verify the duplicated code exists** - Read all locations mentioned
+2. **Check for existing helpers** - Use Grep to search for:

+   - Wait, no - if helper exists and they're NOT using it → `confirmed_valid` (finding is correct)
+   - If no helper exists → `confirmed_valid` (suggest creating one)
+
+**Example:**

+**Before confirming, verify the existing X actually fits the use case:**

+### How to Explore (Bounded)
+
+1. **Read the trigger** - What pattern did the orchestrator identify?
+2. **Form the specific question** - "Do callers handle the new return type?" (not "what do callers do?")
+3. **Use Grep** to find call sites of the changed function/method
+4. **Use Read** to examine 3-5 callers
+5. **Answer the question** - Yes (report issue) or No (move on)
+6. **Stop** - Do not explore callers of callers (depth > 1)
+
+### Trigger-Specific Questions
+
+| Trigger | What to Check in Callers |
+|---------|-------------------------|
+| **Output contract changed** | Do callers assume the old return type/structure? |
+| **Input contract changed** | Do callers pass the old arguments/defaults? |
+| **Behavioral contract changed** | Does code after the call assume old ordering/timing? |
+| **Side effect removed** | Did callers depend on the removed effect? |
+| **Failure contract changed** | Can callers handle the new failure mode? |
+| **Null contract changed** | Do callers have explicit null checks or tri-state logic? |
+
+### Example Exploration
+
+```
+TRIGGER: Output contract changed (array → single object)
+QUESTION: Do callers use array methods?
+
+1. Grep for "getUserSettings(" → found 8 call sites

+3. Read profile.tsx:23 → uses result.email directly → OK
+4. Read settings.tsx:67 → uses .map() on result → ISSUE

 **Your evidence must prove the issue exists - not just that you suspect it.**

+## Evidence Requirements (MANDATORY)
+
+Every finding you report MUST include a `verification` object with ALL of these fields:
+
+### Required Fields
+
+**code_examined** (string, min 1 character)
+The **exact code snippet** you examined. Copy-paste directly from the file:
+```
+CORRECT: "cursor.execute(f'SELECT * FROM users WHERE id={user_id}')"
+WRONG:   "SQL query that uses string interpolation"
+```

+CORRECT: [45, 47]
+WRONG:   [1, 100]  // Too broad - you didn't examine all 100 lines
+```
+
+**verification_method** (one of these exact values)
+How you verified the issue:
+- `"direct_code_inspection"` - Found the issue directly in the code at the location
+- `"cross_file_trace"` - Traced through imports/calls to confirm the issue
+- `"test_verification"` - Verified through examination of test code
+- `"dependency_analysis"` - Verified through analyzing dependencies
+
+### Conditional Fields
+
+**is_impact_finding** (boolean, default false)
+Set to `true` ONLY if this finding is about impact on OTHER files (not the changed file):
+```
+TRUE:  "This change in utils.ts breaks the caller in auth.ts"
+FALSE: "This code in utils.ts has a bug" (issue is in the changed file)
+```
+
+**checked_for_handling_elsewhere** (boolean, default false)
+For ANY "missing X" claim (missing null check, missing bounds check, missing edge case handling):
+- Set `true` ONLY if you used Grep/Read tools to verify X is not handled elsewhere
+- Set `false` if you didn't search other files
+- **When true, include the search in your description:**
+  - "Searched `Grep('if.*null|!= null|\?\?', 'src/utils/')` - no null check found"
+  - "Checked callers via `Grep('processArray\(', '**/*.ts')` - none validate input"

+```
+TRUE:  "Searched for null checks in this file and callers - none found"
+FALSE: "This function should check for null" (didn't verify it's missing)
+```
+
+**If you cannot provide real evidence, you do not have a verified finding - do not report it.**
+
+**Search Before Claiming Absence:** Never claim a check is "missing" without searching for it first. Validation may exist in callers, guards, or type system constraints.
+
+## Valid Outputs
+
+Finding issues is NOT the goal. Accurate review is the goal.
+
+### Valid: No Significant Issues Found
+If the code is well-implemented, say so:
+```json
+{
+  "findings": [],
+  "summary": "Reviewed [files]. No logic issues found. The implementation correctly [positive observation about the code]."

+Do NOT report issues just to have something to say:
+- Theoretical edge cases without evidence they're reachable
+- Style preferences not backed by project conventions
+- "Could be improved" without concrete problem
+- Pre-existing issues not introduced by this PR

+
 ## Your Workflow

-### Phase 1: Analysis
+### Phase 0: Understand the PR Holistically (BEFORE Delegation)
+
+**MANDATORY** - Before invoking ANY specialist agent, you MUST understand what this PR is trying to accomplish.
+
+1. **Check for Merge Conflicts FIRST** - If `has_merge_conflicts` is `true` in the PR context:
+   - Add a CRITICAL finding immediately
+   - Include in your PR UNDERSTANDING output: "⚠️ MERGE CONFLICTS: PR cannot be merged until resolved"
+   - Still proceed with review (conflicts don't skip the review)
+
+2. **Read the PR Description** - What is the stated goal?
+3. **Review the Commit Timeline** - How did the PR evolve? Were issues fixed in later commits?
+4. **Examine Related Files** - What tests, imports, and dependents are affected?
+5. **Identify the PR Intent** - Bug fix? Feature? Refactor? Breaking change?
+
+**Create a mental model:**
+- "This PR [adds/fixes/refactors] X by [changing] Y, which is [used by/depends on] Z"
+- Identify what COULD go wrong based on the change type
+
+**Output your synthesis before delegating:**
+```
+PR UNDERSTANDING:
+- Intent: [one sentence describing what this PR does]
+- Critical changes: [2-3 most important files and what changed]
+- Risk areas: [security, logic, breaking changes, etc.]
+- Files to verify: [related files that might be impacted]
+```
+
+**Only AFTER completing Phase 0, proceed to Phase 1 (Trigger Detection).**
+
+## What the Diff Is For
+
+**The diff is the question, not the answer.**
+
+The code changes show what the author is asking you to review. Before delegating to specialists:
+
+### Answer These Questions
+1. **What is this diff trying to accomplish?**
+   - Read the PR description
+   - Look at the file names and change patterns
+   - Understand the author's intent
+
+2. **What could go wrong with this approach?**
+   - Security: Does it handle user input? Auth? Secrets?
+   - Logic: Are there edge cases? State changes? Async issues?
+   - Quality: Is it maintainable? Does it follow patterns?
+   - Fit: Does it reinvent existing utilities?
+
+3. **What should specialists verify?**
+   - Specific concerns, not generic "check for bugs"
+   - Files to examine beyond the changed files
+   - Questions the diff raises but doesn't answer
+
+### Delegate with Context
+
+When invoking specialists, include:
+- Your synthesis of what the PR does
+- Specific concerns to investigate
+- Related files they should examine
+
+**Never delegate blind.** "Review this code" without context leads to noise. "This PR adds user auth - verify password hashing and session management" leads to signal.
+
+## MANDATORY EXPLORATION TRIGGERS (Language-Agnostic)
+
+**CRITICAL**: Certain change patterns ALWAYS require checking callers/dependents, even if the diff looks correct. The issue may only be visible in how OTHER code uses the changed code.
+
+When you identify these patterns in the diff, instruct specialists to explore direct callers:
+
+### 1. OUTPUT CONTRACT CHANGED
+**Detect:** Function/method returns different value, type, or structure than before
+- Return type changed (array → single item, nullable → non-null, wrapped → unwrapped)
+- Return value semantics changed (empty array vs null, false vs undefined)
+- Structure changed (object shape different, fields added/removed)
+
+**Instruct specialists:** "Check how callers USE the return value. Look for operations that assume the old structure."
+
+**Stop when:** Checked 3-5 direct callers OR found a confirmed issue
+
+### 2. INPUT CONTRACT CHANGED
+**Detect:** Parameters added, removed, reordered, or defaults changed
+- New required parameters
+- Default parameter values changed
+- Parameter types changed
+
+**Instruct specialists:** "Find callers that don't pass [parameter] - they rely on the old default. Check callers passing arguments in the old order."
+
+**Stop when:** Identified implicit callers (those not passing the changed parameter)
+
+### 3. BEHAVIORAL CONTRACT CHANGED
+**Detect:** Same inputs/outputs but different internal behavior
+- Operations reordered (sequential → parallel, different order)
+- Timing changed (sync → async, immediate → deferred)
+- Performance characteristics changed (O(1) → O(n), single query → N+1)
+
+**Instruct specialists:** "Check if code AFTER the call assumes the old behavior (ordering, timing, completion)."
+
+**Stop when:** Verified 3-5 call sites for ordering dependencies
+
+### 4. SIDE EFFECT CONTRACT CHANGED
+**Detect:** Observable effects added or removed
+- No longer writes to cache/database/file
+- No longer emits events/notifications
+- No longer cleans up related resources (sessions, connections)
+
+**Instruct specialists:** "Check if callers depended on the removed effect. Verify replacement mechanism actually exists."
+
+**Stop when:** Confirmed callers don't depend on removed effect OR found dependency
+
+### 5. FAILURE CONTRACT CHANGED
+**Detect:** How the function handles errors changed
+- Now throws/returns error where it didn't before (permissive → strict)
+- Now succeeds silently where it used to fail (strict → permissive)
+- Different error type/code returned
+- Return value changes on failure (e.g., `return true` → `return false`, `return null` → `throw Error`)
+
+**Examples:**
+- `validateEmail()` used to return `true` on service error (permissive), now returns `false` (strict)
+- `processPayment()` used to throw on failure, now returns `{success: false, error: ...}` (different failure mode)
+- `fetchUser()` used to return `null` for not-found, now throws `NotFoundError` (exception vs return value)
+
+**Instruct specialists:** "Check if callers can handle the new failure mode. Look for missing error handling in critical paths. Verify callers don't assume the old success/failure behavior."
+
+**Stop when:** Verified caller resilience OR found unhandled failure case
+
+### 6. NULL/UNDEFINED CONTRACT CHANGED
+**Detect:** Null handling changed
+- Now returns null where it returned a value before
+- Now returns a value where it returned null before
+- Null checks added or removed
+
+**Instruct specialists:** "Find callers with explicit null checks (`=== null`, `!= null`). Check for tri-state logic (true/false/null as different states)."
+
+**Stop when:** Checked callers for null-dependent logic
+
+### Phase 1: Detect Semantic Change Patterns (MANDATORY)
+
+**MANDATORY** - After understanding the PR, you MUST analyze the diff for semantic contract changes before delegating to ANY specialist.
+
+**For EACH changed function, method, or component in the diff, check:**
+
+1. Does it return something different? → **OUTPUT CONTRACT CHANGED**
+2. Do its parameters/defaults change? → **INPUT CONTRACT CHANGED**
+3. Does it behave differently internally? → **BEHAVIORAL CONTRACT CHANGED**
+4. Were side effects added or removed? → **SIDE EFFECT CONTRACT CHANGED**
+5. Does it handle errors differently? → **FAILURE CONTRACT CHANGED**
+6. Did null/undefined handling change? → **NULL CONTRACT CHANGED**
+
+**Output your analysis explicitly:**
+```
+TRIGGER DETECTION:
+- getUserSettings(): OUTPUT CONTRACT CHANGED (returns object instead of array)
+- processOrder(): BEHAVIORAL CONTRACT CHANGED (sequential → parallel execution)
+- validateInput(): NO TRIGGERS (internal logic change only, same contract)
+```
+
+**If NO triggers apply:**
+```
+TRIGGER DETECTION: No semantic contract changes detected.
+Changes are internal-only (logic, style, CSS, refactor without API changes).
+```
+
+**This phase is MANDATORY. Do not skip it even for "simple" PRs.**
+
+## ENFORCEMENT: Required Output Before Delegation
+
+**You CANNOT invoke the Task tool until you have output BOTH Phase 0 and Phase 1.**
+
+Your response MUST include these sections BEFORE any Task tool invocation:
+
+```
+PR UNDERSTANDING:
+- Intent: [one sentence describing what this PR does]
+- Critical changes: [2-3 most important files and what changed]
+- Risk areas: [security, logic, breaking changes, etc.]
+- Files to verify: [related files that might be impacted]
+
+TRIGGER DETECTION:
+- [function1](): [TRIGGER_TYPE] (description) OR NO TRIGGERS
+- [function2](): [TRIGGER_TYPE] (description) OR NO TRIGGERS
+...
+```
+
+**Why this is enforced:** Without understanding intent, specialists receive context-free code and produce false positives. Without trigger detection, contract-breaking changes slip through because "the diff looks fine."
+
+**Only AFTER outputting both sections, proceed to Phase 2 (Analysis).**
+
+### Trigger Detection Examples
+
+**Function signature change:**
+```
+TRIGGER DETECTION:
+- getUser(id): INPUT CONTRACT CHANGED (added optional `options` param with default)
+- getUser(id): OUTPUT CONTRACT CHANGED (returns User instead of User[])
+```
+
+**Error handling change:**
+```
+TRIGGER DETECTION:
+- validateEmail(): FAILURE CONTRACT CHANGED (now returns false on service error instead of true)
+```
+
+**Refactor with no contract change:**
+```
+TRIGGER DETECTION: No semantic contract changes detected.
+extractHelper() is a new internal function, no existing callers.
+processData() internal logic changed but input/output contract is identical.
+```
+
+### How Triggers Flow to Specialists (MANDATORY)
+
+**CRITICAL: When triggers ARE detected, you MUST include them in delegation prompts.**
+
+This is NOT optional. Every Task invocation MUST follow this checklist:
+
+**Pre-Delegation Checklist (verify before EACH Task call):**
+```
+□ Does the prompt include PR intent summary?
+□ Does the prompt include specific concerns to verify?
+□ If triggers were detected → Does the prompt include "TRIGGER: [TYPE] - [description]"?
+□ If triggers were detected → Does the prompt include "Stop when: [condition]"?
+□ Are known callers/dependents included (if available in PR context)?
+```
+
+**Required Format When Triggers Exist:**
+```
+Task(
+  subagent_type="logic-reviewer",
+  prompt="This PR changes getUserSettings() to return a single object instead of an array.
+
+          TRIGGER: OUTPUT CONTRACT CHANGED - returns object instead of array
+          EXPLORATION REQUIRED: Check 3-5 direct callers for array method usage (.map, .filter, .find, .forEach).

+
+          Known callers: [list from PR context if available]",
+  description="Logic review - output contract change"
+)
+```
+
+**If you detect triggers in Phase 1 but don't pass them to specialists, the review is INCOMPLETE.**
+
+### Exploration Boundaries
+
+❌ Explore because "I want to be thorough"
+❌ Check callers of callers (depth > 1) unless a confirmed issue needs tracing
+❌ Keep exploring after the trigger-specific question is answered
+❌ Skip exploration because "the diff looks fine" - triggers override this

-**Why this matters:** Specialist agents sometimes flag issues that don't exist in the actual code. The validator reads the code with fresh eyes to catch these false positives before they're reported.
+5. **Every finding in the final output MUST have:**
+   - `validation_status`: One of "confirmed_valid" or "needs_human_review"
+   - `validation_evidence`: The actual code snippet examined during validation
+   - `validation_explanation`: Why the finding was confirmed or flagged
+
+**If any finding is missing validation_status in the final output, the review is INVALID.**
+
+**Why this matters:** Specialist agents sometimes flag issues that don't exist in the actual code. The validator reads the code with fresh eyes to catch these false positives before they're reported. This applies to ALL severity levels — a LOW false positive wastes developer time just like a HIGH one.

 **Example workflow:**
 ```
-Specialist finds 3 issues → finding-validator validates each →
-Result: 2 confirmed, 1 dismissed → Verdict based on 2 issues
+Specialist finds 3 issues (1 MEDIUM, 2 LOW) → finding-validator validates ALL 3 →
+Result: 2 confirmed, 1 dismissed → Verdict based on 2 validated issues
 ```

-## Confidence Tiers
+**Example validation invocation:**
+```
+Task(
+  subagent_type="finding-validator",
+  prompt="Validate this finding: 'SQL injection in user lookup at src/auth/login.ts:45'. Read the actual code at that location and determine if the issue exists. Return confirmed_valid, dismissed_false_positive, or needs_human_review.",
+  description="Validate SQL injection finding"
+)
+```

-After validation, findings are routed based on confidence scores:
+## Evidence-Based Validation (NOT Confidence-Based)

-| Tier | Score Range | Treatment |
-|------|-------------|-----------|
-| HIGH | >= 0.8 | Included as reported, affects verdict |
-| MEDIUM | 0.5 - 0.8 | Included with "[Potential]" prefix, affects verdict |
-| LOW | < 0.5 | Logged for monitoring, excluded from output |
+**CRITICAL: This system does NOT use confidence scores to filter findings.**

-**Guidelines for assigning confidence:**
- 0.9+ : Direct evidence in code, multiple indicators, clear violation
- 0.8-0.9 : Strong evidence, clear pattern, high certainty
- 0.6-0.8 : Likely issue but some uncertainty, may need context
- 0.4-0.6 : Possible issue, limited evidence, context-dependent
- < 0.4 : Speculation, no direct evidence, likely false positive
+All findings are validated against actual code. The validator determines what's real:
+
+| Validation Status | Meaning | Treatment |
+|-------------------|---------|-----------|
+| `confirmed_valid` | Evidence proves issue EXISTS | Include in findings |
+| `dismissed_false_positive` | Evidence proves issue does NOT exist | Move to `dismissed_findings` |
+| `needs_human_review` | Evidence is ambiguous | Include with flag for human |
+
+**Why evidence-based, not confidence-based:**
+- A "90% confidence" finding can be WRONG (false positive)
+- A "70% confidence" finding can be RIGHT (real issue)
+- Only actual code examination determines validity
+- Confidence scores are subjective; evidence is objective
+
+**What the validator checks:**
+1. Does the problematic code actually exist at the stated location?
+2. Is there mitigation elsewhere that the specialist missed?
+3. Does the finding accurately describe what the code does?
+4. Is this a real issue or a misunderstanding of intent?

 **Example:**
- SQL injection with `userId` in query string: 0.95 (direct evidence)
- Missing null check where input could be null: 0.75 (likely but depends on callers)
- "This might cause issues" without specifics: 0.3 (speculation, will be dropped)
+```
+Specialist claims: "SQL injection at line 45"
+Validator reads line 45, finds: parameterized query with $1 placeholder
+Result: dismissed_false_positive - "Code uses parameterized queries, not string concat"
+```

 ## Multi-Agent Agreement

 When multiple specialist agents flag the same issue (same file + line + category), this is strong signal:

-### Confidence Boost
- If 2+ agents agree: confidence boosted by +0.15 (max 0.95)
- cross_validated field set to true
- source_agents lists all agents that flagged the issue
+### Cross-Validation Signal
+- If 2+ agents independently find the same issue → stronger evidence
+- Set `cross_validated: true` on the merged finding
+- Populate `source_agents` with all agents that flagged it
+- This doesn't skip validation - validator still checks the code

 ### Why This Matters
- Independent verification increases certainty
+- Independent verification from different perspectives
 - False positives rarely get flagged by multiple specialized agents
- Multi-agent agreement often indicates real issues
+- Helps prioritize which findings to fix first

 ### Example
 ```
-security-reviewer finds: XSS vulnerability at line 45 (confidence: 0.75)
-quality-reviewer finds: Unsafe string interpolation at line 45 (confidence: 0.70)
+security-reviewer finds: XSS vulnerability at line 45
+quality-reviewer finds: Unsafe string interpolation at line 45

-Result: Single finding with confidence 0.90 (0.75 + 0.15 boost)
+Result: Single finding merged
        source_agents: ["security-reviewer", "quality-reviewer"]
        cross_validated: true
+        → Still sent to validator for evidence-based confirmation
 ```

 ### Agent Agreement Tracking
 The `agent_agreement` field in structured output tracks:
- `agreed_findings`: Finding IDs where 2+ agents agreed
- `conflicting_findings`: Finding IDs where agents disagreed (reserved for future)
- `resolution_notes`: How conflicts were resolved (reserved for future)
+- `agreed_findings`: Finding IDs where 2+ agents agreed (stronger evidence)
+- `conflicting_findings`: Finding IDs where agents disagreed
+- `resolution_notes`: How conflicts were resolved

 **Note:** Agent agreement data is logged for monitoring. The cross-validation results
 are reflected in each finding's source_agents, cross_validated, and confidence fields.

+
+- **If TRIGGER is present** → Exploration is **MANDATORY**, even if the diff looks correct
+- **If no TRIGGER** → Use your judgment to explore or not
+
+### How to Explore (Bounded)
+
+1. **Read the trigger** - What pattern did the orchestrator identify?
+2. **Form the specific question** - "Do callers handle error cases from this function?" (not "what do callers do?")
+3. **Use Grep** to find call sites of the changed function/method
+4. **Use Read** to examine 3-5 callers
+5. **Answer the question** - Yes (report issue) or No (move on)
+6. **Stop** - Do not explore callers of callers (depth > 1)
+
+### Quality-Specific Trigger Questions
+
+| Trigger | Quality Question to Answer |
+|---------|---------------------------|
+| **Output contract changed** | Do callers have proper type handling for the new return type? |
+| **Behavioral contract changed** | Does the timing change cause callers to have race conditions or stale data? |
+| **Side effect removed** | Do callers now need to handle what the function used to do automatically? |
+| **Failure contract changed** | Do callers have proper error handling for the new failure mode? |
+| **Performance changed** | Do callers operate at scale where the performance change compounds? |
+
+### Example Exploration
+
+```
+TRIGGER: Behavioral contract changed (sequential → parallel operations)
+QUESTION: Do callers depend on the old sequential ordering?
+
+1. Grep for "processOrder(" → found 6 call sites
+2. Read checkout.ts:89 → reads database immediately after call → ISSUE (race condition)
+3. Read batch-job.ts:34 → awaits and then processes result → OK
+4. Read api/orders.ts:56 → sends confirmation after call → ISSUE (email before DB write)
+5. STOP - Found 2 quality issues

+- checkout.ts:89 - Race condition: reads from DB before parallel write completes
+- api/orders.ts:56 - Email sent before order is persisted (ordering dependency broken)

+# PR Template Filler Agent
+
+## Your Role
+
+You are an expert developer filling out a GitHub Pull Request template. You receive the repository's PR template along with comprehensive context about the changes — git diff summary, spec overview, commit history, and branch information. Your job is to produce a complete, accurate PR body that matches the template structure exactly, with every section filled intelligently and every relevant checkbox checked.
+
+## Input Context
+
+You will receive:
+
+1. **PR Template** — The repository's `.github/PULL_REQUEST_TEMPLATE.md` content
+2. **Git Diff Summary** — A summary of all code changes (files changed, insertions, deletions)
+3. **Spec Overview** — The specification document describing the feature/fix being implemented
+4. **Commit History** — The list of commits included in this PR
+5. **Branch Context** — Source branch name, target branch name
+
+## Methodology
+
+### Step 1: Understand the Changes
+
+Before filling anything:
+
+1. **Read the spec overview** to understand the purpose and scope of the work
+2. **Analyze the diff summary** to identify what files changed and what kind of changes were made
+3. **Review the commit history** to understand the progression of work
+4. **Note the branch names** to infer the PR target and type of change
+
+### Step 2: Fill Every Section
+
+For each section in the template:
+
+1. **Identify the section type** — Is it a description field, a checkbox list, a free-text area, or a conditional section?
+2. **Select the appropriate content** based on the change context
+3. **Be specific and accurate** — Reference actual files, components, and behaviors from the diff
+4. **Never leave a section empty** — If a section is not applicable, explicitly state "N/A" or "Not applicable"
+
+### Step 3: Check Appropriate Checkboxes
+
+For checkbox lists (`- [ ]` items):
+
+1. **Check boxes that apply** by changing `- [ ]` to `- [x]`
+2. **Leave unchecked** boxes that don't apply
+3. **Base decisions on evidence** from the diff and spec, not assumptions
+4. **When uncertain**, leave unchecked rather than incorrectly checking
+
+### Step 4: Validate Output
+
+Before returning:
+
+1. **Verify markdown structure** matches the template exactly (same headings, same order)
+2. **Ensure no template placeholders remain** (no `<!-- comments -->` left unfilled where content is expected)
+3. **Check that descriptions are concise** but informative (2-3 sentences for summaries)
+4. **Confirm all checkboxes reflect reality** based on the provided context
+
+## Section-Specific Guidelines
+
+### Description Sections
+
+- Write 2-3 clear sentences explaining what the PR does and why
+- Reference the spec or task if available
+- Focus on the "what" and "why", not implementation details
+
+### Type of Change
+
+- Determine from the spec and diff whether this is a bug fix, feature, refactor, docs, or test change
+- Check exactly one type unless the PR genuinely spans multiple types
+- Use the spec's `workflow_type` field as a strong signal
+
+### Area / Service
+
+- Analyze which directories were modified in the diff
+- `frontend` = changes in `apps/frontend/`
+- `backend` = changes in `apps/backend/`
+- `fullstack` = changes in both
+
+### Related Issues
+
+- Extract issue numbers from branch names (e.g., `feature/123-description` → `#123`)
+- Extract from spec metadata if available
+- Use `Closes #N` format for issues that will be closed by this PR
+
+### Checklists
+
+- **Testing checklists**: Check items that the commit history and diff evidence support
+- **Platform checklists**: Check platforms that CI covers; note if manual testing is needed
+- **Code quality checklists**: Check if the diff shows adherence to the principles mentioned
+
+### AI Disclosure
+
+- Always check the AI disclosure box — this PR is generated by Auto Claude
+- Set tool to "Auto Claude (Claude Agent SDK)"
+- Set testing level based on whether QA was run (check spec context for QA status)
+- Always check "I understand what this PR does" — the AI agent analyzed the changes
+
+### Screenshots
+
+- If the diff includes UI changes (frontend components, styles), note that screenshots should be added
+- If no UI changes, write "N/A - No UI changes" or remove the section if the template allows
+
+### Breaking Changes
+
+- Analyze the diff for API changes, removed exports, changed interfaces, or modified database schemas
+- If no breaking changes are evident, mark as "No"
+- If breaking changes exist, describe what breaks and suggest migration steps
+
+### Feature Toggle
+
+- Check the spec for mentions of feature flags, localStorage flags, or environment variables
+- If the feature is complete and ready, check "N/A - Feature is complete and ready for all users"
+
+## Output Format
+
+Return **only** the filled PR template as valid markdown. Do not include any preamble, explanation, or wrapper — just the completed template content ready to be used as a GitHub PR body.
+
+## Quality Standards
+
+1. **Accuracy over completeness** — It's better to leave a checkbox unchecked than to incorrectly check it
+2. **Evidence-based** — Every filled section should be traceable to the provided context
+3. **Professional tone** — Write as a senior developer would in a real PR
+4. **Concise but informative** — Don't pad sections with filler text
+5. **Valid markdown** — The output must render correctly on GitHub
+
+## Anti-Patterns to Avoid
+
+### DO NOT:
+
+- **Invent information** not present in the provided context
+- **Leave template placeholders** like `<!-- What does this PR do? -->` without replacing them with actual content
+- **Check every checkbox** — only check those supported by evidence
+- **Write vague descriptions** like "This PR makes some changes" — be specific
+- **Add sections** not present in the original template
+- **Remove sections** from the original template — fill or mark as N/A
+- **Hallucinate file names** or components not mentioned in the diff
+- **Guess issue numbers** — only reference issues you can confirm from the branch name or spec
+
+---
+
+Remember: Your output becomes the PR body on GitHub. It should be professional, accurate, and immediately useful for reviewers. Every section should help a reviewer understand what changed, why it changed, and what to look for during review.

+## 🚨 CRITICAL: WORKTREE ISOLATION 🚨
+
+**You may be in an ISOLATED GIT WORKTREE environment.**
+
+Check the "YOUR ENVIRONMENT" section at the top of this prompt. If you see an
+**"ISOLATED WORKTREE - CRITICAL"** section, you are in a worktree.
+
+### What is a Worktree?
+
+A worktree is a **complete copy of the project** isolated from the main project.
+This allows safe development without affecting the main branch.
+
+### Worktree Rules (CRITICAL)
+
+**If you are in a worktree, the environment section will show:**
+
+* **YOUR LOCATION:** The path to your isolated worktree
+* **FORBIDDEN PATH:** The parent project path you must NEVER `cd` to
+
+**CRITICAL RULES:**
+* **NEVER** `cd` to the forbidden parent path
+* **NEVER** use `cd ../..` to escape the worktree
+* **STAY** within your working directory at all times
+* **ALL** file operations use paths relative to your current location
+
+### Why This Matters
+
+Escaping the worktree causes:
+* ❌ Git commits going to the wrong branch
+* ❌ Files created/modified in the wrong location
+* ❌ Breaking worktree isolation guarantees
+* ❌ Losing the safety of isolated development
+
+### How to Stay Safe
+
+**Before ANY `cd` command:**
+
+```bash
+# 1. Check where you are
+pwd
+
+# 2. Verify the target is within your worktree
+# If pwd shows: /path/to/.auto-claude/worktrees/tasks/spec-name/
+# Then: cd ./apps/backend  ✅ SAFE
+# But:  cd /path/to/parent/project  ❌ FORBIDDEN - ESCAPES ISOLATION
+
+# 3. When in doubt, don't use cd at all
+# Use relative paths from your current directory instead
+git add ./apps/backend/file.py  # Works from anywhere in worktree
+```
+
+### The Golden Rule in Worktrees
+
+**If you're in a worktree, pretend the parent project doesn't exist.**
+
+Everything you need is in your worktree, accessible via relative paths.

+
+**Status:** ✅ **COMPLETED**
+**Date:** 2026-01-18
+**Commit:** 84681ae6
+
+---
+
+## What Was Verified
+
+### 1. Build Verification ✅
+- **TypeScript Compilation:** PASSED (no errors in terminal-font settings files)
+- **Production Build:** SUCCESS
+  - Main process bundle: 2,432.02 kB
+  - Preload bundle: 72.25 kB
+  - Renderer bundle: 5,289.67 kB
+- **Bundle Summary:** All assets compiled successfully with no errors
+
+### 2. Integration Points Verified ✅
+
+#### Settings Button (TerminalGrid.tsx)
+```tsx
+// Lines 428-434
+<Button onClick={() => {
+  window.dispatchEvent(new CustomEvent('open-app-settings', { detail: 'terminal-fonts' }));
+}}>
+  <Settings className="h-3 w-3" />
+  Settings
+</Button>
+```
+✅ Positioned left of "Invoke Claude All" button
+✅ Dispatches custom event with 'terminal-fonts' detail
+
+#### Event Listener (App.tsx)
+```tsx
+// Lines 273-286
+useEffect(() => {
+  window.addEventListener('open-app-settings', handleOpenAppSettings);
+  return () => window.removeEventListener('open-app-settings', handleOpenAppSettings);
+}, [handleOpenAppSettings]);
+```
+✅ Listens for 'open-app-settings' events
+✅ Navigates to /settings?section=terminal-fonts
+
+#### Navigation Integration (AppSettings.tsx)
+```tsx
+// Lines 72-92
+export type AppSection = '...' | 'terminal-fonts';
+
+const appNavItemsConfig = [
+  // ...
+  { id: 'terminal-fonts', icon: Terminal }
+];
+
+// Line 208
+case 'terminal-fonts':
+  return <TerminalFontSettings />;
+```
+✅ 'terminal-fonts' in AppSection type
+✅ Navigation item with Terminal icon
+✅ Switch case renders TerminalFontSettings component
+
+#### Translation Keys
+```json
+// en/settings.json & fr/settings.json
+"terminal-fonts": {
+  "title": "Terminal Fonts",
+  "description": "Customize terminal font appearance..."
+}
+```
+✅ Complete English translations
+✅ Complete French translations
+✅ All UI text uses i18n keys
+
+#### Store Subscription (useXterm.ts)
+```tsx
+// Lines 298-336
+useEffect(() => {
+  const updateTerminalOptions = () => {
+    const settings = useTerminalFontSettingsStore.getState();
+    terminal.options.fontFamily = settings.fontFamily.join(', ');
+    // ... all other options
+    terminal.refresh(0, terminal.rows - 1);
+  };
+  const unsubscribe = useTerminalFontSettingsStore.subscribe(updateTerminalOptions);
+  return unsubscribe;
+}, [terminal]);
+```
+✅ Reactive subscription to settings store
+✅ Updates all xterm.js options dynamically
+✅ Cleans up on unmount

+# XState Task State Machine Migration - Summary
+
+**Issue:** #1338
+**PR:** #1575
+**Date:** 2026-01-28
+**Branch:** fix/1524-xstate-clean
+
+## Overview
+
+Migrated task status management from scattered decision logic across multiple handler files to a centralized XState v5 state machine. This eliminates race conditions, inconsistent status updates, and makes the task lifecycle formally defined and testable.
+
+## Critical Dependencies & Blockers
+
+### 1. Windows Credential Manager Fix (Required for Testing)
+**PR:** #1569 - fix(windows): fix Windows Credential Manager authentication
+**Issue:** #1525
+
+This PR includes changes that depend on the Windows authentication fix. We could not complete end-to-end testing without this fix in place. If a different solution is implemented for #1525, we can remove these changes and resubmit.
+
+### 2. spec_runner.py Project Detection Fix
+**Issue:** #1570 - spec_runner.py incorrectly detects auto-claude project as source directory
+
+We encountered and fixed this bug during development as it was blocking our test workflow. The fix is included in this PR.
+
+## Implementation Phases
+
+| Phase | Description | Status |
+|-------|-------------|--------|
+| Phase 1 | Create XState machine definition (task-machine.ts) | ✅ Complete |
+| Phase 2 | Create TaskStateManager singleton wrapper | ✅ Complete |
+| Phase 3 | Integrate into agent-events-handlers.ts | ⏸️ Partially done |
+| Phase 4 | Remove legacy TaskStateMachine class | ❌ Not started |
+
+### Why We Stopped at Phase 2
+
+The original scope was to introduce XState as the new state management approach. Full integration (Phase 3-4) requires:
+
+- Extensive refactoring of agent-events-handlers.ts to remove all legacy decision logic
+- Removing the old TaskStateMachine class entirely
+- Migration of all status persistence to go through XState
+
+We delivered Phases 1-2 to establish the foundation. The current state has both systems running in parallel with XState as primary:
+
+- **XState is primary:** When TaskStateManager returns a valid state transition, that decision is used
+- **Legacy as fallback:** The old TaskStateMachine logic only applies when XState doesn't produce a decision
+- **Safe rollback:** If XState causes issues, the legacy system is still present and can take over
+
+This dual-system approach allows:
+- Validation that XState produces correct state transitions in production
+- Safe rollback if issues arise
+- Incremental adoption path for Phase 3-4
+
+## What Changed
+
+### Before (Old Architecture)
+- Status decisions scattered across agent-events-handlers.ts, execution-handlers.ts, worktree-handlers.ts
+- `validateStatusTransition()` function with complex conditional logic
+- TaskStateMachine class that was essentially an event emitter wrapper
+- Multiple places persisting status to implementation_plan.json
+- Race conditions possible when multiple handlers tried to update status
+
+### After (New Architecture)
+- **Single source of truth:** TaskStateManager (XState-based singleton)
+- **Formal state machine:** taskMachine with explicit states and transitions
+- **Centralized persistence:** Status written to JSON from one place
+- **Testable:** Unit tests verify all state transitions
+- **Observable:** XState actors can be inspected/visualized
+
+## State Machine States
+
+```
+backlog → planning → coding → qa_review → qa_fixing → human_review → done
+                  ↘ plan_review ↗              ↓
+                                             error
+```
+
+| State | Maps to Legacy Status | reviewReason |
+|-------|----------------------|--------------|
+| backlog | backlog | - |
+| planning | in_progress | - |
+| coding | in_progress | - |
+| plan_review | human_review | plan_review |
+| qa_review | ai_review | - |
+| qa_fixing | ai_review | - |
+| human_review | human_review | completed or stopped |
+| creating_pr | human_review | completed |
+| pr_created | pr_created | - |
+| error | human_review | errors |
+| done | done | - |
+
+## Key Files
+
+| File | Purpose |
+|------|---------|
+| `apps/frontend/src/shared/state-machines/task-machine.ts` | XState machine definition |
+| `apps/frontend/src/main/task-state-manager.ts` | Singleton service wrapping XState actors |
+| `apps/frontend/src/shared/state-machines/__tests__/task-machine.test.ts` | State machine unit tests (35 tests) |
+| `apps/frontend/src/main/__tests__/task-state-manager.test.ts` | Manager service unit tests (20 tests) |
+| `apps/frontend/src/main/ipc-handlers/agent-events-handlers.ts` | Refactored to call TaskStateManager |
+
+## Events
+
+The state machine responds to these events:
+
+| Event | Triggered By |
+|-------|-------------|
+| PLANNING_STARTED | Execution progress phase=planning |
+| PLANNING_COMPLETE | Execution progress moving past planning |
+| PLAN_APPROVED | User clicks "Proceed to Coding" from plan_review |
+| CODING_STARTED | Execution progress phase=coding |
+| QA_STARTED | Execution progress phase=qa_review |
+| QA_PASSED | Execution progress phase=complete |
+| QA_FAILED | Execution progress phase=qa_fixing |
+| PROCESS_EXITED | Agent process exit event |
+| USER_STOPPED | User clicks stop |
+| USER_RESUMED | User resumes task |
+| MARK_DONE | User marks task as done |
+| CREATE_PR | User initiates PR creation |
+| PR_CREATED | PR successfully created |
+
+## Rollback Plan
+
+If issues arise post-merge:
+
+1. **Quick rollback:** `git revert <merge-commit>`
+2. **Restore point:** Commit 3e5f004a has old code intact
+3. **Legacy persistence still works:** implementation_plan.json continues to store status
+
+## Testing
+
+| Test Suite | Result |
+|------------|--------|
+| Frontend unit tests | ✅ 2579 passed |
+| TypeScript strict mode | ✅ Pass |
+| Biome lint | ✅ Pass |
+| XState machine tests | ✅ 35 passed |
+| TaskStateManager tests | ✅ 20 passed |
+| Python backend tests | ✅ Pass |
+
+## Session Fixes (2026-01-28)
+
+### Fixed Issues
+
+1. **Badge showing "Needs Review" instead of "Complete"** - Added `effectiveReviewReason` logic in TaskCard.tsx that sets 'completed' when phase === 'complete'
+
+2. **Task showing "Incomplete" badge for plan_review** - Added 'plan_review' to exclusion list in `isIncompleteHumanReview`
+
+3. **Missing "Proceed to Coding" button** - Restored in WorkspaceMessages.tsx for plan_review flow
+
+4. **Wrong XState event for plan_review → coding** - Fixed to send PLAN_APPROVED instead of PLANNING_STARTED when starting from plan_review state
+
+5. **Stuck detection logic** - Reverted useTaskDetail.ts to simpler logic from working branch (only skip 'planning' phase, 2s timeout)
+
+## Outstanding Items (Requires PM Input)
+
+### 1. Future: Subtask XState Migration
+- **Issue:** `subtask.status` is checked directly in UI code
+- **Recommendation:** Should be managed by state machine for consistency
+- **Status:** Out of scope for current PR, document for future work
+
+## Future Improvements
+
+- Add @stately-ai/inspect for runtime devtools
+- **Subtask state management** - Track individual subtask states within the machine using XState parallel states
+- Add more granular QA states (qa_round_1, qa_round_2, etc.)
+- Complete Phase 3-4: Full integration and removal of legacy TaskStateMachine class
