# Tasks

## 1. Simulation core

- [ ] 1.1 Implement Conway tick using a second grid buffer and swap, verifying a known pattern (blinker) oscillates.
- [ ] 1.2 Add tick timing in the frame loop with adjustable interval, verifying ticks occur at configured rate.

## 2. Controls

- [ ] 2.1 Wire pause/step/speed actions to simulation state, verifying pause stops ticks and step advances one generation.
- [ ] 2.2 Add default key bindings for p/n/+/- and verify config tests pass.

## 3. Editing

- [ ] 3.1 Implement paused-only cell editing on left/right click, verifying clicks change cell state only when paused.
- [ ] 3.2 Implement drag painting while paused, verifying drag sets/clears cells.

## 4. Verification

- [ ] 4.1 Build and run ctest, verifying all tests pass.
- [ ] 4.2 Manual run: verify pause, step, speed, editing, and Esc.
