+- On the owner's request: t12 (exotic ores) and t31 (choosing claims) merged into t13, now
+  "Distinct worlds: generation options, planet presets, exotic ores and a choice of claims";
+  t24 (water fixes) merged into t21, now "Code health: refactor, speed up and test the physics".
+  t2 and t14 rewritten with subtasks. t12, t24 and t31 archived (`tasks/archive/`), not deleted.

+Water never seems to run out in certain conditions when its running off the edge. maybe it actually does but it takes a while and i just didnt notice. Please do a full test suite of water physics and make sure it asks as it should in all conditions.

 ## Context
 
-- add more world generation options in new world creation and some presetsa Presets like different planet environments and all. Trees, water, dirt, all that could look different too.
+- Every world is generated the same way today, and a new claim is just another random world the same size as the last. Make worlds and claims feel distinct: options when generating a world, planet presets that change how a world looks and what is in it, exotic late-game ores that only some worlds have, and a choice of claims to open, each with its own size, character and price. (Merged from t12 exotic ores and t31 choosing claims.)
+
+## Subtasks
+
+- [ ] Generation options in the new-world dialog: how much ore, caves, water and mountains, and how deep the world goes
+- [ ] Planet presets that change the look and the climate: different trees, water, dirt and rock colours, for example a frozen world, a desert world and a volcanic world
+- [ ] Exotic, sci-fi ores and materials for the late game, found only on some planets or very deep, each with a use
+- [ ] Opening a new claim offers a few claims to choose from (for example three), each showing its size, preset, notable ores, down payment and debt
+- [ ] Claim prices match their size and riches

 ## Context
 
-- lets talk about upgrades to the res drill. currently we have a bit mold. but that doesnt really make sense for the res drill. lets redesign the whole upgrades functionality anyway.
+- The Resonance drill is upgraded today by casting drill bits in a Bit mold, which doesn't make sense for a drill that shatters rock with pulses. Redesign how upgrades work as a whole. Earlier ideas from the design notes: an amplifier, a tuning fork and harmonics for the drill, a Grav pick tool and mining charges.
+
+## Subtasks
+
+- [ ] Decide what the drill's upgrades are (power, reach, width, tuning, harder rock) and how each is earned or built, replacing the Bit mold
+- [ ] Decide whether other upgrades (the bag/tank, Flask, thermal lens) follow the same system
+- [ ] Old saves keep the upgrades they already have

+title: Code health: refactor, speed up and test the physics
+---
+
+## Context
+
+- The code has grown fast. Clean it up and make it faster without changing how the game plays, and give the physics a full test pass, starting with water: water running off the edge of the world never seems to run out (it may only be slow; find out, and fix it if it really doesn't). (Merged from t24 water fixes.)
+
+## Subtasks
+
+- [ ] Remove duplicated code and split the largest modules into smaller files
+- [ ] Profile the simulation and rendering on a Huge world and speed up the slowest parts
+- [ ] A full test pass over water physics in every situation (pools, flows, falls off the world edge, pumps and pipes, freezing and boiling); fix what is wrong
+- [ ] The same kind of pass over sand, molten metal and gases where tests are thin
+- [ ] Fix issues found along the way, and test every piece of gameplay the changes touch

 ## Context
 
-- lets think about how best to design the factory products. basics are normal smelting ore, refining, etc. but the actual export products could be like real construction materials. materials that a real construction site might need.
+- Decide what the factory ultimately makes for sale. Smelting ore, grinding rock and casting bars are the basics; the products worth exporting should be real construction materials, the things an actual building site orders. Some exist already (stone blocks, planks, bricks, glass bricks, metal bars); this is about designing the full set and how each is made.
+
+## Subtasks
+
+- [ ] List candidate products a building site buys (for example steel beams, rebar, pipe, wire, glass panes, cement and concrete, roof tiles) and pick the ones that fit the game
+- [ ] For each, decide its recipe from materials in the game and which machine or mold makes it
+- [ ] Builders' orders and prices for them, so making finished products pays better than selling raw bars
