7fa81c6bb9 perf: reduce core live-memory footprint by 45% on large maps (#4507)
## Summary

Reduces the simulation's steady-state memory footprint. On Giant World
Map at 20 game-minutes (12 000 ticks, 400 bots, seed `perf-default`),
live memory after a full GC drops **293 MB → 161 MB (−45%)**; unforced
peak heap drops **326 MB → 165 MB**. The simulation also runs ~10%
faster (85 → 94 ticks/s). The final game-state hash is **bit-identical**
(`57830793797434300`) — no behavior change.

## Measurement (first commit)

The full-game perf harness gains a footprint mode:

- `--footprint` — forces a full GC at every `--window` boundary and
records the live heap / ArrayBuffer / RSS curve across the game
(requires `NODE_OPTIONS=--expose-gc`).
- `--snapshot-at 0,2000,12000` — writes V8 `.heapsnapshot` files at
chosen ticks.
- `HeapSnapshotRetainers.ts` — attributes every heap node to its nearest
meaningfully-named retainer (e.g. `PlayerImpl._tiles`), plus prints
retainer chains for all nodes ≥128 KB. `HeapSnapshotSummary.ts` is a
streaming fallback for snapshots too large to `JSON.parse`.

Baseline attribution at tick 12 000: player `_tiles`/`_borderTiles` Sets
**83 MB**, GameMap `refToX`/`refToY` lookup tables **38 MB**, two
duplicate 30.5 MB visited-scratch arrays, trade-ship stepper paths **15
MB**, a construction-only flood-fill queue **9.5 MB**.

## Optimizations

**Map-sized buffers (second commit):**
- `GameMap.x()/y()` compute `ref % width` / `(ref / width) | 0` instead
of reading two per-tile Uint16 tables (−38 MB). The arithmetic is
cheaper than the tables' random-access cache misses — this is where the
speedup comes from.
- `PlayerExecution` and `SpatialQuery` each kept their own per-game
generation-stamped visited `Uint32Array`; both now share one via
`TileTraversalScratch` (−30 MB).
- `PathFinderStepper` stores numeric paths as `Uint32Array` (half the
bytes; steppers hold their full path for a unit's whole journey).
- `ConnectedComponents` frees its flood-fill queue after `initialize()`.

**Player tile sets (third commit):**
- New `TileSet`: insertion-ordered set of tile refs backed by a dense
`Uint32Array` plus an open-addressing hash index — ~12 bytes/element vs
~34 for a native `Set<number>`. Deletes tombstone; compaction is
deferred while iteration is in progress so positions never shift under
an iterator.
- Iteration semantics match `Set` exactly (insertion order, entries
added mid-iteration visited, deleted ones skipped, delete+re-add moves
to end) — the simulation relies on this order for determinism, and the
unchanged hash confirms it.
- `Player.borderTiles()` now returns `ReadonlyTileSet` (a native `Set`
still satisfies it structurally); `GameRunner.playerBorderTiles` copies
into a real `Set` since that result crosses the worker boundary via
structured clone.

## Footprint curve (giant world map, live MB after forced GC)

| checkpoint | before | after |
|---|---|---|
| spawn end | 20 + 100 buf | 20 + 55 buf |
| tick 6301 | 119 + 161 buf | 29 + 127 buf |
| tick 12301 | 130 + 161 buf | 32 + 129 buf |

## Validation

- Final hash `57830793797434300` identical across baseline / round 1 /
round 2 runs (12 000 ticks).
- Full suite passes (1798 + 126 tests), including new `TileSet` tests:
order semantics, mutation-during-iteration parity with `Set`, tombstone
compaction, and a 20 000-op randomized differential test against native
`Set`.
- Runs recorded in
`tests/perf/output/footprint-{baseline,round1,round2}-giant.txt`.

blonandGitHub 3c196cb7e7 crit fix: indian subcontinent map crash (#4479)
Resolves #4401

NOTE: While this PR is an improvment, the Indian subcontinent crash IS
NOT caused by >253 water components, as the map only has ~15 water
components.

## Description:

Fixes a critical browser tab crash ("Aw, Snap! Something went wrong")
when loading the game on the new Indian Subcontinent map (or any map
with >= 253 water components) in Solo Mode.

### Technical Cause:
1. When a map contains >= 253 disconnected water components, the array
mapping tiles to component IDs is dynamically promoted from a Uint8Array
to a Uint16Array.
2. This promotion upgrades the land sentinel LAND_MARKER from 0xff (255)
to LAND_MARKER_WIDE (0xffff / 65535).
3. The BFS local search filter in AStarWaterHierarchical had a hardcoded
sentinel check: (t: TileRef) => this.graph.getComponentId(t) !==
LAND_MARKER (evaluating against 255).
4. On promoted maps, land tiles (65535) matched this check as water. The
local BFS then traversed the entire landmass of the map, resulting in
CPU exhaustion and memory/stack overflows that crashed the rendering
process.

### Solution:
Changed the hardcoded sentinel check to query the map's terrain directly
via this.map.isWater(t). This makes the check immune to any component ID
promotions or sentinel representation upgrades. Verified that the
existing water pathfinding test suite passes successfully.

## Please complete the following:

- [ ] I have added screenshots for all UI updates (N/A)
- [ ] I process any text displayed to the user through translateText()
and I've added it to the en.json file (N/A)
- [x] I have added relevant tests to the test directory (Existing tests

pathfinding behavior and run successfully)

22d5aba5ae refactor: standardize cardinal-neighbor iteration on neighbors() N,S,W,E order (#4495)
## Summary

Follow-up to #4494. That PR added `forEachNeighborNSWE` as a third
neighbor iterator because the existing allocation-free helpers
(`forEachNeighbor`, `neighbors4`) visit in W,E,N,S order while
`neighbors()` visits N,S,W,E — and substituting one for the other
changes simulation behavior at order-sensitive call sites.

This PR removes that duplication by standardizing on **one order
everywhere**: `forEachNeighbor` and `neighbors4` now visit in the same
N,S,W,E order as `neighbors()`, and `forEachNeighborNSWE` is deleted.

## ⚠️ Intentional behavior change

Callers of the flipped helpers that are order-sensitive now make
different (equally valid) decisions:

- `AttackExecution.addNeighbors` — PRNG values are drawn per neighbor
while building the conquest frontier, so attack expansion patterns
differ
- `AttackExecution.handleDeadDefender` — a dead defender's tiles go to
the *first-visited* adjacent player
- `WarshipExecution.bestNeighborToward` — distance ties break by visit
order
- `PlayerExecution` surrounded-cluster flood fill — set insertion order
propagates to conquer order

Game outcomes for a given seed differ from previous builds (verified:
the 12k-tick reference run ends with 31 players alive vs 24 before).
Determinism across clients *within* a build is unaffected — all clients
run the same code, so there is no desync risk. Replays/verification
pinned to old hashes will not match this build.

New reference hashes for the headless perf harness (seed
`perf-default`):

| Run | Final hash |
|---|---|
| giantworldmap, 12,000 ticks | `57830793797434300` |
| giantworldmap, 2,000 ticks | `55125379638382860` |
| world, 1,800 ticks | `32337437717390864` |

## Verification

- [x] Full suite green (1,901 tests), including new exact-order contract
tests: `forEachNeighbor` and `neighbors4` must match `neighbors()`
contents **and order** for every tile
- [x] 20-game-minute Giant World Map benchmark: no perf regression (73
ticks/sec, GC 1.2% of wall, allocation profile unchanged)
- [x] Order-sensitivity audit of every `forEachNeighbor`/`neighbors4`
call site (sensitive ones listed above; the rest are booleans, counts,
or min/max accumulations)

5e4b2791aa perf: reduce core-sim GC churn 42% and add GC-churn profiling to the perf harness (#4494)
## Summary

Reduces core-simulation GC churn by **42%** on a 20-game-minute Giant
World Map run, and extends the headless full-game perf harness so churn
is measurable and regressions are visible.

### 1. GC-churn measurement (`tests/perf/fullgame/GcProfiler.ts`)

`npm run perf:game` now reports:

- **GC pauses** by kind (minor/major/incremental) via a
`PerformanceObserver` on `'gc'` entries, bucketed into tick windows by
timestamp (V8 only delivers these entries on a timer task, so they're
flushed after the run)
- **Allocation rate** per `--window N` ticks (default 1000) from
used-heap deltas sampled every tick, so churn can be tracked across game
phases
- **Top allocating functions** from the V8 sampling heap profiler with
`includeObjectsCollectedBy{Major,Minor}GC` — i.e. actual churn including
short-lived garbage, not live memory — plus a `.heapprofile` loadable in
Chrome DevTools (Memory → Allocation sampling)

New flags: `--window N`, `--no-gc-profile`, `--no-alloc-profile`.

### 2. Allocation reductions in the hot paths it found

| Site | Change |
|---|---|
| `GameMap.bfs` | inline neighbor enumeration instead of an array per
visited tile |
| `GameMap`/`Game` | new `forEachNeighborNSWE` — allocation-free
iterator matching `neighbors()` N,S,W,E order for order-sensitive
callers (`forEachNeighbor` visits W,E,N,S, so substituting it would
change sim behavior) |
| `PlayerImpl.nearby` / `sharesBorderWith` / `shoreReachableNeighbors` |
no per-call neighbor arrays; no materialized shore-tile array |
| `PlayerImpl.units(types)` | gather into a reusable scratch buffer,
return one exact-size slice (still a fresh snapshot array per call) |
| `AiAttackBehavior.maybeAttack` | single pass over border neighbors
replacing the `flatMap`/`filter`/`map` chain over every border tile |
| `AiAttackBehavior.isBorderingNukedTerritory` | reusable `neighbors4`
buffer with early exit |
| `SharedWaterCache.build` | allocation-free neighbor iteration |
| `SpatialQuery.bfsNearest` | first-minimum scan instead of
collect-then-stable-sort (identical result incl. tie-breaking) |

### Results (Giant World Map, 400 bots, 12,000 ticks ≈ 20 game-minutes,
seed `perf-default`)

| Metric | Before | After |
|---|---|---|
| Sampled allocations (incl. collected) | 97.7 GB | **56.9 GB (−42%)** |
| GC count / total pause | 1,682 / 3,313 ms (1.8% of wall) | 1,058 /
2,087 ms (1.2%) |
| Ticks/sec | 66 | 70 |
| p99 / max tick | 49.9 ms / 988 ms | 43.5 ms / 689 ms |
| Ticks over 100 ms budget | 31 | 19 |

## Determinism

Every rewrite preserves exact iteration order (the new NSWE iterator
exists precisely for the order-sensitive sites). Verified by identical
final game-state hashes on three runs: Giant World Map 12,000 ticks
(`67286276735690560`), Giant World Map 2,000 ticks, and World 1,800
ticks.

## Test plan

- [x] Full suite green (1,896 tests)
- [x] New tests: `forEachNeighborNSWE` order contract vs `neighbors()`
over every tile; `units()` filtering semantics (insertion order,
fresh-array guarantee, duplicate types, Set path)
- [x] Final-hash equality on 3 seeded headless runs (2 maps)

FloPinguinandGitHub 805f0968b1 Add impassable terrain 🗺️ (#4340)
## Description:

Relates to #3725

Adds a new **Impassable** terrain type that enables non-rectangular maps
and creates impassable barriers on the map. Painted with pure black
(`#000`) in the map editor's `image.png`.

**Encoding:** Impassable terrain is encoded in the binary format as
`isLand=1, magnitude=31` (previously unused). The Go map generator
detects `#000` pixels and produces this encoding. The map generator's
minimap downscaling gives impassable highest priority (Impassable >
Water > Land). Thumbnails render impassable as transparent so the map
picker background shows through.

**Rendering:** Impassable tiles render as the map background colour
(`rgb(60, 60, 60)`, matching `gl.clearColor` in `Renderer.ts`), making
them visually indistinguishable from the area outside the map quad. This
enables maps to appear non-rectangular.

**Gameplay restrictions:** Impassable terrain cannot be:
- Owned (`conquer()` throws)
- Attacked (`AttackExecution` skips impassable tiles in both `tick()`
and `addNeighbors()`)
- Nuked (targeting rejected in `nukeSpawn()`, blast radius filtered in
`tilesToDestroy()`)
- Spawned on (nations, human players, and structures all reject
impassable tiles)
- Converted to water (guarded in `WaterManager` and `setWater()`)

**Nuke trajectories:** Nuke trajectories cannot cross impassable
terrain, matching the existing map-border enforcement. This is checked
at launch time in `NukeExecution.tick()`. The client-side trajectory
preview turns red with a red X where the arc crosses impassable terrain
(reusing the existing SAM-intercept visual pipeline in
`NukeTrajectory.ts`). The nuke ghost preview is completely hidden when
hovering over impassable terrain (same as hovering outside the map).

2789db8b96 Optimize core simulation hot paths (no behavior change) (#4230)
## Summary

Pure performance optimizations to the attack/conquer/cluster hot paths
in `src/core`, driven by the full-game perf harness from #4228. **No
behavior change**: the final game-state hash is identical before/after
on every config tested — world quick run (2 different seeds),
giantworldmap, and the default 1800-tick run.

### Changes

- **Flat-arithmetic neighbor iteration**: `forEachNeighbor` /
`forEachNeighborWithDiag` / `isBorder` / `isOceanShore` are now
implemented inside `GameMapImpl` using raw `ref±1` / `ref±width` index
math, skipping the per-neighbor `ref()` coordinate validation
(`Number.isInteger` etc.). `GameImpl` and `GameView` delegate.
- **New `neighbors4(ref, out)`**: zero-allocation, callback-free
neighbor query for hot loops (W, E, N, S — same order as
`forEachNeighbor`).
- **`AttackExecution`**: the per-tile closures in `tick()` /
`addNeighbors()` are replaced with reusable neighbor buffers, a cached
`GameMap` reference, and integer `smallID()` owner comparisons instead
of owner-object lookups.
- **`GameImpl`**: the per-conquer `updateBorders` closure is hoisted to
a method with a reusable buffer; `removeInactiveExecutions` compacts the
executions array in place instead of allocating a new ~4200-element
array every tick.
- **`PlayerExecution`**: `surroundedBySamePlayer` / `isSurrounded` /
`getCapturingPlayer` de-closured (`neighbors4` + integer compares;
neighbor visit order preserved, so `getCapturingPlayer`'s
Map-insertion-order tie-breaking is unchanged); flood-fill visit closure
hoisted out of the while loop.
- **`FlatBinaryHeap.dequeue`**: returns the tile directly instead of
allocating a `[tile, priority]` tuple per dequeued tile (AttackExecution
is the only caller).

### Performance (`npm run perf:game`, same machine, before → after)

| run | mean tick | ticks/sec | max tick |
|---|---|---|---|
| default (world, 400 bots, 1800 ticks) | 9.04 → **7.98 ms** | 111 →
**125** | 31.7 → 35.7 ms |
| giantworldmap, 600 ticks | 22.5 → **17.4 ms** | 44 → **58** | 52.8 →
**36.2 ms** |

The giantworldmap tail improvement (max tick −31%) is the most relevant
for the 100 ms tick budget.

### Determinism verification

Identical `Final hash` before and after on all configs:

| config | hash |
|---|---|
| `--map world --ticks 200 --bots 100` | `5455008589403520` |
| same + `--seed second-seed-check` | `5580840142777488` |
| `--map giantworldmap --ticks 600` | `37373734953428430` |
| default run | `26773450321979388` |

### Tests

- New `tests/NeighborIteration.test.ts` pins the exact neighbor
iteration orders (W,E,N,S cardinal; dx-major diagonal — conquest order
and RNG consumption depend on them) and conquer/border-tile invariants
checked mid-battle.
- New `tests/FlatBinaryHeap.test.ts` covers heap ordering, clear, and
growth.
- Full suite passes (122 files / 1386 tests + server tests); lint and
prettier clean.

I removed isLake from the nametag position calculation

Because isLake was unused then, I removed it completely.

Full changelog:

- Remove isLake() from GameMap interface, GameMapImpl, GameImpl, and
GameView
- Remove TerrainType.Lake enum value
- terrainType() now returns Ocean for all water tiles (previously
distinguished lake vs ocean, but nothing treated them differently)
- Remove Lake case from PastelTheme and PastelThemeDark (already fell
through to Ocean)
- Exclude lakes from nametag placement grid in NameBoxCalculator

Maybe as a next step also remove lakes metadata from the map generator?

evanpelle 5b663fae14 refactor: share renderer state shapes between game and WebGL renderer
PlayerView/UnitView now wrap renderer-shaped state objects (PlayerState,
PlayerStatic, UnitState) directly instead of holding engine wire types.
GameView owns a long-lived FrameData object kept in sync each tick:
players/units/tiles/trail/railroad are mutated in place; derived buffers
(playerStatus, relationMatrix, allianceClusters, nukeTelegraphs,
attackRings) and events are recomputed in a final populateFrame() pass.

The renderer reads gameView.frameData() and the same byte-identical
state objects PlayerView/UnitView wrap. WebGLFrameBuilder shrinks from
~270 to ~70 LOC: palette management + a single uploadFrameData() call,
no per-frame UnitState allocation on the hot path.

Wiring: maxPlayers=1024 on RendererConfig (pre-sizes NamePass/palette/
relation matrix textures); NamePass disabled so HTML NameLayer remains
the only on-screen player names.

Also: 39 new tests covering PlayerView/GameView/FrameData behavior;
replace .data field access in three layer call sites with accessor
methods (betrayals(), type(), getTraitorRemainingTicks()).

FloPinguinandGitHub 0801cad0b5 Fix NaN coordinates in Warship patrol logic 🚢 (#3697)
## Description:

This PR fixes the `Invalid coordinates: NaN,NaN` crash during Warship
patrol execution.

### Root cause

`WarshipExecution.randomTile` picks a patrol destination inside
`warshipPatrolRange / 2` of the current patrol tile. When a search fails
to find a valid tile, the range expands by 50% per retry (`100 → 150 →
225 → 337`) and becomes odd. Once odd, `warshipPatrolRange / 2` is a
float (e.g. `112.5`), which is handed straight to
`PseudoRandom.nextInt`:

```ts
Math.floor(this.rng() * (max - min)) + min;
```

With a float `min`, this returns `integer + float` - a float. Despite
its name, `nextInt` was silently returning a non-integer. From there:

- `x = mg.x(patrolTile) + floatOffset` → float
- `mg.isValidCoord(floatX, floatY)` → `true` (only bounds were checked)
- `mg.ref(floatX, floatY)` → `yToRef[floatY] + floatX` → `undefined +
float` → `NaN`
- `hasWaterComponent(NaN, …)` → `miniMap.ref(NaN, NaN)` → **throw**

### Why this only started crashing recently

The float‑leaking `nextInt` bug has been latent since at least the
pathfinding refactor (#2866, January), which introduced the
`hasWaterComponent` check. It was invisible because the guard directly
above it short‑circuited on `NaN`:

```ts
if (!this.mg.isOcean(tile) || (!allowShoreline && this.mg.isShoreline(tile))) continue;
```

For a `NaN` tile ref, `terrain[NaN]` is `undefined`, so:

- `isOcean(NaN)` → `Boolean(undefined & OCEAN_BIT)` → **`false`**
- `isLand(NaN)` → **`false`**
- `isWater(NaN)` → `!isLand(NaN)` → **`true`**

Before: `!isOcean(NaN)` was `true`, execution hit `continue`, and the
poisoned ref never reached `hasWaterComponent`. The "Trading in lakes"
PR (#3653) relaxed that single line to allow patrol on lakes:

```diff
- if (!this.mg.isOcean(tile) || ...) continue;
+ if (!this.mg.isWater(tile) || ...) continue;
```

Because `isWater(NaN)` is `true`, `!isWater(NaN)` is now `false` -
execution falls through to `hasWaterComponent(NaN, …)` and crashes.
#3653 didn't introduce the bug; it just happened to remove the
accidental NaN filter that was hiding it.

### Changes

- **`PseudoRandom.nextInt`** - root‑cause fix. Floors both `min` and
`max` so `nextInt` always returns an integer regardless of what callers
pass. Future callers can't re‑trip this trap.
- **`WarshipExecution.randomTile`** - replaced the unsafe
`this.warship.patrolTile()!` non‑null assertion with a proper
`undefined` guard that returns early.
- **`GameMap.isValidCoord`** - defense in depth: also requires
`Number.isInteger(x)` and `Number.isInteger(y)`. Non‑integer coords can
still be produced outside `nextInt` (trig, arithmetic); this makes
`ref()` fail loudly at the boundary instead of silently producing `NaN`
refs.

FloPinguinandGitHub 7f7cbba12f Water-Nukes 💧 (#3604)
## Description:

Adds a new `waterNukes` game config option that causes nuclear
detonations to convert land tiles into water instead of just leaving
fallout. When enabled, nuked land tiles are batched and converted to
water each tick, with full terrain metadata updates including:

- Ocean bit propagation from adjacent ocean tiles (BFS flood fill)
- Magnitude recomputation via BFS from remaining coastlines
- Shoreline bit fix-up in a 2-ring neighborhood around converted tiles
- Minimap terrain sync (majority-rule downsampling)
- Throttled water navigation graph rebuild (every 20 ticks) for ship
pathfinding
- Ship executions detect graph rebuilds and refresh their pathfinders
- TransportShips auto-retreat if their destination becomes water
- Water nuke craters use a smoothed angular noise ring with a
bounding-box scan instead of the regular per-tile random coin flip with
BFS, producing clean blob-shaped craters without scattered land pixels
that players would have to boat to individually

The `TerrainLayer` now incrementally repaints tiles that changed terrain
type, and tile update packets encode the terrain byte alongside tile
state so clients can reflect water conversions in real time.

When `waterNukes` is disabled, behavior is unchanged (fallout only).

Includes a new test suite (WaterNukes.test.ts) covering the conversion
pipeline, ocean propagation, magnitude recalculation, shoreline updates,
and minimap sync.

Also adds a new public game modifier for the special rotation.

### The only problem
A bit of lag on impact. But otherwise it works great and is fun. Maybe
needs some followup improvements if it gets merged.
I think its very cool in baikal / four islands team games. Chip away the
territory of your opponents.
Its also fun to turn The Box / Alps into a water map (its actually
possible to boat-trade then)

scamivandGitHub ea2a76609f perf(core): speed up packedTileUpdates (Uint32 pairs, no tile wrappers) (#3255)
## Description
Reduces CPU + GC pressure from tile update serialization.

**What changed**
- Switched `packedTileUpdates` from `BigUint64Array` (BigInt packing) to
`Uint32Array` `[tileRef, state]` pairs, updating `GameView` ingestion.
- Updated tile state to use `GameMap.tileState(tile)` and
`GameMap.updateTile(tile, state)`.
- Removed per-tile `GameUpdateType.Tile` wrapper allocations by
recording raw `(tile, state)` pairs in `GameImpl` and draining them via
`drainPackedTileUpdates()` in `GameRunner`.

**Why it’s faster**
- Avoids BigInt and pack/unpack.
- Avoids per-tile object allocations.

**Compatibility**
- Wire format change: `packedTileUpdates` is now `Uint32Array` pairs
instead of `BigUint64Array`.

bibizuandGitHub 664d66613b fix: Check alliance breakage once at launch, and is deterministic now (#2554)
## Description:

Removes the check to break alliance after nuke is launched, and alliance
breaking is now determined before tiles are randomly chosen for
destruction. (It is now slightly stricter, I believe, as a weighted
average calculation is a little tricky)

Aaron TidwellandGitHub 9ab1319126 Map Generator Go Code Documentation (#2656)
Resolves #2602

## Description:
tldr: `npm run docs:map-generator`

Adds documentation to the `map-generator` go code.

This has no functional changes, other than the renaming of the package.
I used the github url, though this can be set to anything as long as it
contains a `.` so that the docs parse it correctly. Go doc best
practices seem a little verbose and terse, but attempted to comply

Future Facing (to get these docs viewable without running locally):
- Wait until the -http issue is sorted, then these are easy to
statically host alongside builds
- Could use the legacy `godoc`
- Could do formatting after outputting the `txt` output


## Change List:

- Add documentation to all types/fns in map-generator go code
- Ensure this outputs correctly with `go doc`
- Add `docs:map-generator` command to package.json. This runs `go doc`
in `map-generator` w/ appropriate flags to generate full documentation.
(see notes in readme)
- rename `map-generator` module to work around pkgsite assuming all
packages without a . are stdlib (this makes `-http` work at all)
- Add new sections to README and update existing sections
- Add additional references to locations in the primary code base where
things can be found
- Update documentation in the ts theme files to add output color
mappings - this ensures that everything needed to trace the input file
-> in game rendered asset is fully documented.


## Please complete the following:

- [X] I have added screenshots for all UI updates
- [X] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [X] I have added relevant tests to the test directory
- [X] I confirm I have thoroughly tested these changes and take full

evanpelleandGitHub b48770faf0 Move maps generation out of repo, new map structure (#1256)
## Description:

Move map generation outside of main repo, it has been rewritten in Go
and is much faster. Also refactor how maps are stored, one dir per map.
The map binaries are basically identical to before. Some maps like
Africa have 1% difference in bytes, but playing it looks exactly the
same.

Use lazy loading for map data access so only needed files are accessed.

Unit tests now load map binary instead of regenerating it from scratch,
speeding them up.

70745faac4 Enable strictNullChecks, eqeqeq (#436)
## 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.

Fixes #466

729920bdca Avoid sqrt for euclideanDist function (#395)
## Description:

In most cases we do not need to solve for the hypotenuse length and can
do math directly on the square of the hypotenuse. For example, the
common use case for calculating euclidean distance is to check if two
points are within a certain distance of each other. In this case,
`Math.sqrt(x*x + y*y) < d` can be rewritten as `x*x + y*y < d*d`.
