# RedFlag Project Backlog System

This directory contains the structured backlog for the RedFlag project. Each task is documented as a standalone markdown file with detailed implementation requirements, test plans, and verification steps.

## 📁 Directory Structure

```

├── README.md              # This file - System overview and usage guide
├── INDEX.md               # Master index of all backlog items

```

## 🎯 Priority System

### Priority Levels
- **P0 - Critical:** Production blockers, security issues, data loss risks
- **P1 - Major:** High impact bugs, major feature gaps
- **P2 - Moderate:** Important improvements, medium-impact bugs
- **P3 - Minor:** Small enhancements, low-impact bugs
- **P4 - Enhancement:** Nice-to-have features, optimizations
- **P5 - Future:** Research items, long-term considerations

### Priority Rules
- **P0 = Must fix before next production deployment**
- **P1 = Should fix in current sprint**
- **P2 = Fix if time permits**
- **P3+ = Backlog for future consideration**

## 📋 Task Lifecycle

### 1. Task Creation
- Tasks are created when issues are identified during development, testing, or user feedback
- Each task gets a unique ID: `P{priority}-{sequence}_{descriptive-title}.md`
- Tasks must include all required sections (see Task Template below)

### 2. Task States
```mermaid
stateDiagram-v2
    [*] --> TODO
    TODO --> IN_PROGRESS
    IN_PROGRESS --> IN_REVIEW
    IN_REVIEW --> DONE
    IN_PROGRESS --> BLOCKED
    BLOCKED --> IN_PROGRESS
    TODO --> WONT_DO
    IN_REVIEW --> TODO
```

### 3. State Transitions
- **TODO → IN_PROGRESS:** Developer starts working on task
- **IN_PROGRESS → IN_REVIEW:** Implementation complete, ready for review
- **IN_REVIEW → DONE:** Approved and merged
- **IN_PROGRESS → BLOCKED:** External blocker encountered
- **BLOCKED → IN_PROGRESS:** Blocker resolved
- **IN_REVIEW → TODO:** Review fails, needs more work
- **TODO → WONT_DO:** Task no longer relevant

### 4. Completion Criteria
A task is considered **DONE** when:
- ✅ All "Definition of Done" items checked
- ✅ All test plan steps executed successfully
- ✅ Code review completed and approved
- ✅ Changes merged to target branch
- ✅ Task file updated with completion notes

## 📝 Task File Template

Each backlog item must follow this structure:

```markdown
# P{priority}-{sequence}: {Brief Title}

**Priority:** P{X} ({Critical|Major|Moderate|Minor|Enhancement|Future})
**Source Reference:** {Where issue was identified}
**Date Identified:** {YYYY-MM-DD}
**Status:** {TODO|IN_PROGRESS|IN_REVIEW|DONE|BLOCKED|WONT_DO}

## Problem Description
{Clear description of what's wrong}

## Reproduction Steps
{Step-by-step instructions to reproduce the issue}

## Root Cause Analysis
{Technical explanation of why the issue occurs}

## Proposed Solution
{Detailed implementation approach with code examples}

## Definition of Done
{Checklist of completion criteria}

## Test Plan
{Comprehensive testing strategy}

## Files to Modify
{List of files that need changes}

## Impact
{Explanation of why this matters}

## Verification Commands
{Commands to verify the fix works}
```

## 🚀 How to Work with Backlog

### For Developers

#### Starting a Task
1. **Choose a task** from `INDEX.md` based on priority and dependencies
2. **Check status** - ensure task is in TODO state
3. **Update task file** - change status to IN_PROGRESS, assign yourself
4. **Implement solution** - follow the proposed solution or improve it
5. **Run test plan** - execute all test steps
6. **Update task file** - add implementation notes, change status to IN_REVIEW
7. **Create pull request** - reference the task ID in PR description

#### Task Example Workflow
```bash
# Example: Working on P0-001
cd docs/3_BACKLOG/

# Update status in P0-001_Rate-Limit-First-Request-Bug.md
# Change "Status: TODO" to "Status: IN_PROGRESS"
# Add: "Assigned to: @yourusername"

# Implement the fix in codebase
# ...

# Run verification commands from task file
curl -I -X POST http://localhost:8080/api/v1/agents/register \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"hostname":"test"}'

# Update task file with results
# Change status to IN_PROGRESS or DONE
```

### For Project Managers

#### Sprint Planning
1. **Review INDEX.md** for current priorities and dependencies
2. **Select tasks** based on team capacity and business needs
3. **Check dependencies** - ensure prerequisite tasks are complete
4. **Assign tasks** to developers based on expertise
5. **Set sprint goals** - focus on completing P0 tasks first

#### Progress Tracking
- Check `INDEX.md` for overall backlog status
- Monitor task files for individual progress updates
- Review dependency map for sequence planning
- Use impact assessment for priority decisions

### For QA Engineers

#### Test Planning
1. **Review task files** for detailed test plans
2. **Create test cases** based on reproduction steps
3. **Execute verification commands** from task files
4. **Report results** back to task files
5. **Sign off tasks** when all criteria met

#### Test Execution Example
```bash
# From P0-001 test plan
# Test 1: Verify first request succeeds
curl -s -w "\nStatus: %{http_code}, Remaining: %{x-ratelimit-remaining}\n" \
  -X POST http://localhost:8080/api/v1/agents/register \
  -H "Authorization: Bearer $TOKEN" \
  -d '{"hostname":"test","os_type":"linux","os_version":"test","os_architecture":"x86_64","agent_version":"0.1.17"}'

# Expected: Status: 200/201, Remaining: 4
# Document results in task file
```

## 🔄 Maintenance

### Weekly Reviews

- **Wednesday:** Check for new issues to add
- **Friday:** Update INDEX.md with completion status

### Monthly Reviews
- **New task identification** from recent issues
- **Priority reassessment** based on business needs
- **Dependency updates** as codebase evolves

## 📊 Metrics and Reporting

### Key Metrics
- **Cycle Time:** Time from TODO to DONE
- **Lead Time:** Time from creation to completion
- **Throughput:** Tasks completed per sprint
- **Blocker Rate:** Percentage of tasks getting blocked

### Reports
- **Sprint Summary:** Completed tasks, velocity, blockers
- **Burndown Chart:** Remaining work over time
- **Quality Metrics:** Bug recurrence, test coverage
- **Team Performance:** Individual and team velocity

## 🎯 Current Priorities

Based on the latest INDEX.md analysis:

### Immediate Focus (This Sprint)
1. **P0-004:** Database Constraint Violation (enables audit trails)
2. **P0-001:** Rate Limit First Request Bug (unblocks new installs)
3. **P0-003:** Agent No Retry Logic (critical for reliability)
4. **P0-002:** Session Loop Bug (fixes user experience)

### Next Sprint
5. **P1-001:** Agent Install ID Parsing (enables upgrades)
6. **P1-002:** Agent Timeout Handling (reduces false errors)

## 🤝 Contributing

### Adding New Tasks
1. **Identify issue** during development, testing, or user feedback
2. **Create task file** using the template
3. **Determine priority** based on impact assessment
4. **Update INDEX.md** with new task information
5. **Notify team** of new backlog items

### Improving the Process
- **Suggest template improvements** for better task documentation
- **Propose priority refinements** for better decision-making
- **Share best practices** for task management and execution
- **Report tooling needs** for better backlog tracking
