> Phase: {current phase number/name}

## Task Context

{What you're working on and why}

## Key Findings

{Critical discoveries and insights - be specific with file paths and line numbers}

## Files Analyzed

| File              | Purpose     | Status   |
| ----------------- | ----------- | -------- |
| path/file.cs:line | description | ✅/🔄/⏳ |

## Progress

- [x] Completed items
- [ ] In-progress items
- [ ] Remaining items

## Important Context

{Information that must be preserved - decisions, assumptions, rationale}

## Next Steps

1. {Immediate next action}
2. {Following action}

## Recovery Instructions

{Exact steps to resume: which file to read, which line to continue from}
