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.

**Planning file inspection** I need to focus on building and inspecting the files. It's important to ensure everything is in order before moving forward. I might have to check for any inconsistencies or issues in the files. This part can be tedious, but it's essential to make sure everything aligns correctly. Having a solid foundation is the key to success, so I’ll take the time to thoroughly go through them!

**Designing canvas controls** I'm working on creating better top HTML controls for a panel overlay, using CSS for the body. The canvas will show a room with a tank centered on a floor, scaling the canvas at 1200x800 while being responsive. I’ll place the buttons in an absolute position at the top overlay. I need to draw a wall background and manage the water dynamics in the tank, ensuring elements like fish, rocks, and plants have realistic movement and interactions.**Understanding dynamics in the tank** I'm considering how rocks behave in the tank. They sink due to gravity but can initially settle at the bottom. Currents might push them occasionally. Toys can float, moving along the x-axis with enough variation. Fish initially swim to the left to counteract the current, which flows to the right, but some might get caught in the current. It’s essential to think through these dynamics to create a realistic underwater environment!**Analysing water dynamics** I'm considering how water volume affects tank level. The amount of puddle relates to water loss, and it spreads out. The width of the puddle is proportional to the lost fraction up to 280, alongside its height. I'm imagining the floor blob restricted by the walls at x=1150, and the puddle spreads right and left from under the jet, spanning x from 840 onward. For crack positioning, I can drag the mouse along a zigzag in the wall at x=840, between specific heights.**Evaluating tank wall damage** I’m noticing an opening around a crack in the tank wall, with some missing segments and shards. There's a crack line that seems to be right before a breach, and I can see a handle glowing. There's a dragging indicator and some instructions related to it. I’ll need to address the breach button overlay at the top and make a reset as well. It looks like I’ll also have to prepare one HTML for this.

**Calculating water depth** I need to determine the water depth over an opening based on the difference between the opening height and the water height. It should be positive until the surface is above the hole. There’s a vertical radius of about ±34 around the opening, and I still need to consider that if the surface goes up to the top of the opening. I can define this head as the difference between crack height and the water height adjusted with the radius.

**Evaluating fish response** I'm noticing the early outflow creates a clear curved arc. Some fish respond by getting near the breach, which is interesting! The waterline looks to be around y190, possibly a few seconds after the frame since the tool captured it. I might need to sample the motion after some time. It looks like I'll need to use a motion tool to analyze this further. It's a bit of a puzzle, but I'm on it!

**Analyzing buoyancy and movement** I’m considering that while buoyancy may not apply, plants seem to bend instead. I notice how fish are pushed by currents, yet they often escape in random directions. It seems like toy rides will only open once the waterline drops and makes contact, which is a good observation. I need to focus on fixing the rendering for those that have escaped and verify everything with an initial reset after clicking it. That's my first step!

**Checking reset process** I need to check the reset function. I should click the reset button and take a screenshot, probably capturing the current state of the waterline. My click coordinates are x168 and y55, so I'll make sure I'm hitting the right spot. It's important to verify that everything resets correctly, so I’ll keep a close eye on the details!

**Evaluating object behavior** I'm looking at how escaped objects are behaving when they collide with the floor. I need to ensure their body positions are updated correctly in the frame. I think I have already checked for escaped fish while considering their movements. I also want to perform an additional check after a click and at 0.5 seconds with drag at a specific point. It might help to fix the shard drag issue and add currents for fish, making them swim against the current initially.

**Checking syntax and testing** I need to make sure I check for any syntax issues by reloading and triggering a sample. We previously only tested small changes, but now it’s time to reload everything and assess with a new setup. I want to reset the initialization automatically, then click through the breach and take a screenshot or motion capture. It's important to capture this for proper documentation. Let's make sure everything is in order!

**Analyzing mouse movement adjustments** I’m looking at a potential bug related to the mouse movement. It seems like there's a crack at the y-coordinate of 385 and an initial waterline at y190. I might need to create some motion around there. Earlier, I had some movement, but the modifications are only rendering the escaped fish with velocity. I think doing a single motion for 500ms could be okay, and then I can reset it afterward.

**Evaluating water levels** I’m assessing the waterline, which continues to fall from 190 to 330, with an outflow at 32%. The fish are being swept through and are now visibly moving out while I notice gravity affecting the floor. There’s a toy near a hole, but it's still by the wall as the surface drops. It feels like a good point to reset everything back to the initial scene, as required.

Implemented the self-contained simulation in **`index.html`**. I checked the initial tank, dragged the crack, triggered a breach, and observed a downward-curving jet, falling waterline, spreading puddle, and fish swept out and falling under gravity. Reset restored the intact scene. The browser console showed no application errors. Not fully verified: the full run until outflow stops, every fragment/object collision case, and small-screen touch behavior.
