Prompt for this run

Build an interactive 2D aquarium-breach simulation on a canvas. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Initially show an intact glass tank containing water, fish, rocks, plants, and a floating toy. Let the user drag a visible crack vertically on one side below the initial waterline, then press Breach. Provide Reset to restore the same initial scene. - On Breach, show the panel breaking around the selected opening. Water exits in a gravity-curved jet, and the waterline falls continuously. Outflow weakens as the water level approaches the opening and stops when water no longer reaches it. - Escaped water forms a spreading puddle constrained by the floor and room walls. - Model distinct responses to buoyancy, drag, and current: rocks sink, the toy floats, plants bend or drift, and fish initially swim against the current before some are swept through the breach. Movable objects that fit the opening can be carried out by the flow. - Objects leaving the water transition to gravity-driven motion and collide with the floor. Glass fragments rotate, collide, and experience resistance in water. - Simplified, internally consistent physics is sufficient; a full computational-fluid-dynamics solver is not required. Verify: Position the crack, trigger a breach, and sample the early outflow. Check that the jet curves downward, the waterline begins to fall, and nearby objects respond to the current. Use Reset and check that the tank returns to its intact initial state.

The user wants me to build an interactive 2D aquarium-breach simulation as a single-page web app in `index.html`. This is a complex physics simulation with:

1. A glass tank with water, fish, rocks, plants, and a floating toy
2. User-draggable crack on one side below the waterline
3. Breach button that shows water spraying out
4. Water line falling, puddle formation
5. Physics for different objects (rocks sink, toy floats, plants bend)
6. Fish behavior (swim against current, some swept through)
7. Glass fragment physics
8. Reset functionality

Let me build this step by step, making it comprehensive but doable within the constraints.

Key design decisions:
- Canvas-based rendering
- Custom physics engine (simplified but consistent)
- Particle systems for water jet and puddle
- Object types: rocks (sink), toy (float), plants (bend/drift), fish (swim)
- Glass crack interaction and breach animation
- Water level calculation based on breach point

Let me write this out as a complete, self-contained HTML file.

Now let me open the file in the browser and test the various behaviors:
1. Draw a crack
2. Trigger breach
3. Check jet behavior, water level, object responses
4. Reset and verify clean state

The initial output looks great - the aquarium scene is rendering correctly with fish, rocks, plants, and a floating toy. The UI is working with the Breach and Reset buttons. Now I need to verify the full interactive behavior:

1. Can the user draw a crack on the right wall below the waterline?
2. Does pressing Breach show the panel breaking with water exiting?
3. Does the waterline fall continuously?
4. Does outflow weaken as water level approaches the opening?
5. Does escaped water form a spreading puddle?
6. Do rocks sink, toy float, plants bend, fish swim against current then get swept out?
7. Do glass fragments rotate and collide with gravity?
8. Does Reset restore the initial state?

Let me test these interactions by:
1. Drawing a crack on the right wall
2. Clicking Breach
3. Observing the physics simulation
4. Clicking Reset
5. Verifying the scene returns to initial state

Let me start by drawing a crack.

Let me test the full interactive behavior. First, I'll draw a crack on the right wall, then trigger Breach and verify the physics. **Test 1: Draw a crack and trigger Breach** <tool_call>bash {"command": "cd /tmp/job-YxhC6s && cat > test_aquarium.py << 'PYEOF'\nimport time, subprocess, os\nfrom playwright.sync_api import sync_playwright\n\nwith sync_playwright() as p:\n browser = p.chromium.launch(headless=True)\n page = browser.new_page()\n page.goto(f'file:///tmp/job-YxhC6s/index.html')\n \n # Wait for page to load\n page.wait_for_load_state('load')\n print(\"Page loaded\")\n \n # 1.
