## Description:
Bug (before): In multi-nuke scenarios (e.g., 6 incoming nukes), SAMs,
when stacked, could behave like they only engage one nuke at a time,
letting other nukes slip through and wipe the SAM stack. This was most
noticeable when nukes entered from certain angles/entry sides (from what
I’ve noticed, it happens more often in the 2 o’clock to 6 o’clock
direction).

/>
What was fixed:
1- Removed permanent "unreachable" caching: When a nuke was out of SAM
range on first evaluation, it was cached as null (permanently
unreachable) and never re-evaluated. Since nukes move each tick, they
could later enter interception range but would be ignored. The fix
removes this permanent cache, so nukes are re-evaluated every tick.
2 - Moved targetedBySAM filter into the targeting system: The
targetedBySAM() check was at the launch decision, if the
highest-priority nuke was already claimed by another SAM, the launcher
skipped firing entirely instead of falling back to the next best target.
The fix moves the filter inside getSingleTarget() so claimed nukes are
excluded before ranking.
3 - Cleared targetedBySAM flag on SAM missile abort: When a SAM missile
aborted (for example target became allied), the targetedBySAM flag was
never cleared. This permanently prevented all other SAMs from targeting
that nuke. The fix calls setTargetedBySAM(false) on abort so the nuke
becomes available for re-targeting.
**Videos:**
I uploaded a before/after clip showing SAM performance intercepting 6
nukes, before the fix, nukes could break through, but after the fix,
SAMs consistently intercept as expected.

## Pathfinding Refactor pt. 2
<img width="1536" height="1024" alt="image"

This is a follow-up to a previous PR introducing pathfinding changes.
This time, it introduces a complete refactor of `pathfinding` directory
and breakdown into composable pieces.
### Unified PathFinder interface
`PathFinder<T>` and `SteppingPathFinder<T>` are introduced to unify
**all** pathfinding across the application. First one exposes complete
path, while stepping variant allows the callee to iterate over the path
by calling `.next`. All pathfinders share this one common interface,
which makes them easy to use in any scenario -
`PathFinding.Water(game).search(from, to)`.
`SteppingPathFinder<T>` extends `PathFinder<T>` with an ability to
iterate over the path. It handles caching, storing current index and
invalidation. This allows the units to not care about the inner workings
of the pathfinder and just call `pf.next(current, target)` and receive
instructions on what to do next.
### Common entry point
All pathfinders are now exposed from common `PathFinding` entrypoint:
- `PathFinding.Water`
- `PathFinding.Rail`
- `PathFinding.Stations`
- `PathFinding.Rail`
Additional entry point is introduced for pathfinders which need to work
both in the worker, but also on the frontend, which lacks `Game`
interface. Currently only `UniversalPathFinding.Parabola` is available.
### Spatial Query
New module has been introduced close to `pathfinding` - `SpatialQuery`.
It aims to resolve any questions game may have about finding tiles
meeting criteria. Currently `SpatialQuery.closestShore(player, target)`
and `SpatialQuery.closestShoreByWater(player, target)` are available -
they help answering questions about naval invasion: "What is the best
landing location from user's click?" and "Which our tile should be used
to launch the transport ship?". Under the hood they use very similar
mechanics to pathfinding, so it felt right to put them close by.
### Modular architecture
Pathfinders now support transformers: `MiniMapTransformer`,
`ShoreCoercingTransformer`, `ComponentCheckTransformer`,
`SmoothingTransformer`. Transformers functions like a middleware in the
pathfinding chain. They wrap around the pathfinder and provide
additional functionality. This allows the pathfinder to focus on
actually finding the path instead of doing unrelated things.
Example chain for simple (A*) water pathfinding:
```ts
static WaterSimple(game: Game): SteppingPathFinder<TileRef> {
const miniMap = game.miniMap();
const pf = new AStarWater(miniMap);
return PathFinderBuilder.create(pf)
.wrap((pf) => new ShoreCoercingTransformer(pf, miniMap))
.wrap((pf) => new MiniMapTransformer(pf, game.map(), miniMap))
.buildWithStepper(tileStepperConfig(game));
}
```
The Pathfinder - here `AStarWater` - does not care about the conversion
between minimap and main map tiles. It also does not care if the source
or destination is a land tile. The transformers take care of that. The
pathfinder gets a set of valid coordinates and produces the path -
that's it.
Modular approach makes working on a particular set of utilities much
easier - for example map upscaling is handled consistently across all
pathfinders. Additionally, the pathfinders are not tied to the
particular map resolution used. Pass them a different map and they will
work the same.
### Algorithms
Algorithms used are neatly organized inside
`src/core/pathfinding/algorithms`. They are prefixed with the algorithm
name and suffixed with the use case. File without suffix exposes generic
version ready to traverse any graph with adapters. Specialized versions
either use an adapter or inline logic when performance is critical -
using adapters leads to 20-30% performance loss.
The directory includes `A*` and `BFS` but also other useful utils, such
as `AbstractGraph` used to generate... an abstract graph on top of the
tile map and `ConnectedComponents` helping to identify whether two tiles
are connected by a path without actually computing the path.
### Playground
The playground have been updated with new algorithms, including tweaked
very greedy `A*`.

src="https://github.com/user-attachments/assets/1f833651-0024-4299-bf86-882f5368358c"
/>
### Tests
Yeah, there are some, a little too many if I say so myself. But there
are no useless tests. I had to ensure refactored code works somehow
reliably. This PR comes with trust me bro guarantee, but I would
appreciate someone confirming **naval invasions, nukes (esp. MIRV) and
warships**.

## Description:
Current SAM behavior is to shoot a missile as soon as a nuke is in
range.
Players can exploit it by overshooting behind the SAM, so the SAM
missile will take way longer to reach the nuke, usually too late to
prevent its explosion.
This PR introduces a "smart" targeting system that allows SAM to
calculate an optimal interception tile along the nuke's trajectory. They
can also preshot before the nuke becomes vulnerable, as long as the
interception tile will be within the vulnerable window.
This change makes SAM range enforcement much more strict.
Changes:
- Nukes now precompute their full trajectory on creation and update
their current position index every tick.
- SAMs use this trajectory data and their own missile speed to calculate
the ideal interception tile.
- SAM missiles now aim directly at that interception point rather than
chasing the nuke.
Small changes on the fly:
- `BezierCurve` now uses a provided increment so the curve LUT is the
optimal size
- Increased nuke opacity when untargetable: 0.4 → 0.5
- Slightly extended nuke vulnerability range to SAMs: 120 → 150
===
Preshot an incoming nuke still in the unfocusable state. Notice how the
nuke is destroyed as soon as becomes focusable:

## Description:
Improve type safety and runtime correctness by:
1. Enabling TypeScript's
[strictNullChecks](https://www.typescriptlang.org/tsconfig/#strictNullChecks)
compiler option.
2. Replacing all loose equality operators (`==` and `!=`) with strict
equality operators (`===` and `!==`).
3. Cleaning up of type declarations, null handling logic, and equality
expressions throughout the project.
Currently, the code allows implicit assumptions that `null` and
`undefined` are interchangeable, and relies on type-coercing equality
checks that can introduce subtle bugs. These practices make it difficult
to reason about when values may be absent and hinder the effectiveness
of static analysis.
Migrating to strict null checks and enforcing strict equality
comparisons will clarify intent, reduce bugs, and make the codebase
safer and easier to maintain.

when an building is taken over by another player the execution for it
doesnt change its owner this makes it so when a sam is captured it tries
to intercept your own nukes and doesnt intercept the ones by the
previous player
this change makes executions of buildings automaticly switch their owner
More costly (start at 1.5M), increase cost cap (4.5M), biggest timeout
(5s->10s), much lower chance to stop hydrogen (70%->10%), triple
construction time (10s->30s) otherwise it's trivial to build a SAM right
before a nuke hits
