## 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).

src="https://github.com/user-attachments/assets/7ca6c9ef-b2b4-47ea-bed2-249a84c8f5ed"
/>
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.

## Description:
As far as I can remember, in v28 the spawn immunity applied to both
humans and nations.
With the configurable spawn immunity (added for v29) the spawn immunity
no longer applies to nations... Because its called PVP immunity now.
So right now it's possible to spawnkill nations. This is a big problem
for the 5M gold modifier games... And you can "cheat" in singleplayer.
This PR changes two things:
- Nations always have 5 seconds spawn immunity now, no matter whats
configured for the PVP immunity
- Nations attack TerraNullius earlier (Otherwise the easy nations would
sometimes do their first attack after the 5 seconds are over, spawnkills
would still be possible)

#2716 introduced nuke cancellation logic on alliance acceptance via
`AllianceRequestReplyExecution`. The radial menu action, though, calls
`AllianceRequestExecution` instead, which accepts the alliance if a
request has already been made by the other player.
This PR moves the nuke cancellation logic to `GameImpl`, hooking into
the `acceptAllianceRequest` method, therefore accounting for every
alliance acceptance, regardless of the specific action that brought to
that.

## Description:
When a train station is removed, the clusters are recomputed. However
the cluster recomputation code has not been changed from the original
rail network implementation, which was a tree.
The deletion code made assumptions that are not true anymore since we
introduced loops in the network. As a result the cluster recomputation
was very inefficient, although the data was correct.
Changes:
- Fix clusters computation when a structure is deleted
- Structures are frequently deleted in bulk: atom/hydro/MIRV.
Re-computing the clusters when a single structure is deleted would be
inefficient because the recomputed cluster would probably need to be
recomputed again in the same tick.
Instead, when a structure is deleted, flag the cluster as "dirty", and
recompute all the dirty clusters once per tick only.
Previous performances (hydro over a dense area):

## Description:
- Remove alliances on death: after death, alliances would stay active
including countdown timers and (when dead player kept spectating) icons.
Now remove them when player becomes inActive.
- Moved code to private method within PlayerExecution + added comments
in NationExecution and BotExecution for more clarity as to where
removals are performed from at death
- Remove renewal request from Events Display when Alliance doesn't exist
anymore (after death or otherwise).
- Also cleanup this.alliancesCheckedAt when alliance doesn't exist
anymore. Before, old/broken alliance id's would accumulate in it during
a game.
- Removed now-redundant isAlive check in EventsDisplay. Both the
alliances array as the isAlive are updated in the same tick from
PlayerUpdates so now alliance is removed from alliances array on player
death, the other.isAlive() check is no longer needed. Of course we could
keep it in just to be very safe, so just let me know when you're
doubtful about this.
- Attack.test.ts: fix failing test. Player B dies because of the attack,
meaning the alliance now gets removed. Prevent this by gving both a
different, adjecent, starting tile. And to be more clear about what is
needed for the test to pass, add isAlive check for both of them after
the attacks.

## Description:
**3 problems:**
* Nation difficulty steps in `DefaultConfig` don't look good (max
troops: 0.5 → 1 → 1.125 → 1.25).
* We previously reduced the difficulty of easy nations for singleplayer,
but now they are too easy for public FFAs.
* In Discord we discussed HvN difficulty and concluded that a 50% human
win rate (my previous target) is too low; nations should be easier.
This PR addresses all of them:
* Difficulty steps in `DefaultConfig` are now cleaner (max troops: 0.5 →
0.75 → 1 → 1.25).
* Nation difficulty in public-game FFAs is restored to *medium* (0.75
max troops - still weaker than humans, but not too weak).
* HvN difficulty (medium) is now easier.
Regarding singleplayer:
These rebalances make nation difficulties more beginner-friendly, while
experts still have their challenge at *Impossible*.

## Description:
### New stuff
- Nations can upgrade structures now. They do it if they have too many
structures compared to their territory size
- They prefer to upgrade stuff thats protected by SAMs (based on
difficulty)
- Updated the build order, it also depends a bit on the difficulty now
(easy nations build less SAMs)
- Nations can handle extreme amounts of gold now. 500M starting gold? no
problem. Previously they only built cities
- They stop saving up for MIRV if they can afford it (in some old Enzo
"impossible difficulty experiment" videos you could see nations with
like 300M gold...)
- The save-up-target changes when bombs / hydros / MIRVs are disabled
- Added many checks for disabled units. For example: Don't build SAMs
when missile silos are disabled, focus on factories when ports are
disabled
- Updated the `structureSpawnTileValue` method, SAM-placement depends a
bit on the difficulty now
### Refactor
- Moved all structure related nation code into
`NationStructureBehavior.ts`
- Split up the good old `structureSpawnTileValue` method to make it more
readable
- Cleaned up NationExecution a bit

## Description:

The `RailroadLayer` simply displays tiles as instructed by the core
worker. While it's practical for the layer to only care about the tiles,
it also means it has no understanding of railroads as entities (their
paths, connections, or identities).
It also means that the core worker is responsible for rendering tasks
such as tile orientation and construction animation, which is not
expected.
To support ID-based events and better separation of concerns, the
rendering layer needs to be aware of complete railroads. With this
change, the core worker can send the tiles once and subsequently
reference railroads only by ID for all other events.
#### Changes:
- `RailroadLayer` now stores full railroad data instead of only
individual tiles
- `RailroadLayer` is responsible for animating newly built railroads
- Add a new `RailroadSnapUpdate` sent when a new structure is built over
an existing railroad. This event is used by `RailroadLayer` to keep
railroad ID in sync.
- When hovering over a railroad, the render worker is querying the core
worker about overlapping railroads.
Alternatively, RailroadLayer could compute overlaps itself now that it
has full railroad knowledge, but this logic would need to be duplicated
and kept in sync across workers. Keeping a single source of truth in the
core worker is preferred.
#### Edgecases:
- When a structure snaps over a railroad, the original railroad is split
into two new railroads. If the construction animation is still in
progress, instead of resuming the animation at the correct point on the
new railroads, all remaining tiles are rendered immediately
- Previously, `RailroadUpdate` handled both construction and
destruction. This no longer works with `RailroadSnapUpdate`, as event
ordering is now pretty important and IDs may be lost before they are
consumed.
To address this, RailroadUpdate is split in two:
`RailroadConstructionUpdate` and `RailroadDestructionUpdate`.

## Summary
Refactor `generateTeamColors()` to use LCH (Lightness-Chroma-Hue) color
space instead of HSL for perceptually uniform team color variations.
## Changes
- **`Colors.ts`**: Rewrite `generateTeamColors()` to use LCH color space
- Golden angle hue distribution clamped to ±12° to preserve team
identity
- Chroma oscillates ±10% around the base to add variety without washing
out
- Lightness alternates ±18 around the base to keep teammates
recognizable
## Why LCH?
LCH is a perceptually uniform color space, meaning equal numeric
differences correspond to equal perceived differences. This produces
team color variations that look more consistent and distinguishable
compared to HSL-based generation.

## Description:
Like Atom and H-bombs, MIRV warheads should still land after the
launching player died. PlayerExecution already makes sure to skip nukes
when deleting a dead player's units. But MIRVexecution separate()
creates NukeExecutions which check canBuild, which returns false for a
dead player.
Fix: Skip alive and cost check for MIRV warheads. canBuild is only
applicable when creating the MIRV itself, not at the seperation stage
mid-flight. There's no cost involved either.
Note: this bug has been there since MIRVs were added to the game. But
the bug wasn't noticed often in all that time. Still the fix may have
some impact on gameplay.

The change focuses on `Cluster` trade destination lookup and how
`TrainStationExecution` picks a destination.
## What changed
### 1) Maintain a “trade-capable” station subset per cluster
`src/core/game/TrainStation.ts`
- `Cluster` now maintains:
- `stations`: all stations in the cluster (unchanged)
- `tradeStations`: maintained subset of stations that can act as trade
endpoints (`City` or `Port`)
- `tradeStations` is kept in sync in:
- `addStation()`
- `removeStation()`
- `clear()`
Impact:
- Trade queries no longer scan every station in the cluster; they only
scan `tradeStations`.
### 2) Add cheap eligibility helpers
`src/core/game/TrainStation.ts`
- `hasAnyTradeDestination(player)`:
- Fast early-exit check: returns as soon as it finds any eligible trade
destination.
- `randomTradeDestination(player, random)`:
- Picks a random eligible trade destination directly without
materializing an intermediate `Set`.
### 3) Use reservoir sampling for single-pass random choice
`src/core/game/TrainStation.ts`
`Cluster.randomTradeDestination()` uses reservoir sampling:
- Iterates `tradeStations` once.
- Maintains a running count of eligible stations (`eligibleSeen`).
- Replaces the selected station with probability `1/eligibleSeen`.
Properties:
- Uniform selection among eligible stations.
- One pass instead of “count then pick by index” (two pass).
- Allocation-free.
- Returns `null` when no eligible destination exists.
### 4) Update train spawning to avoid temporary sets
`src/core/execution/TrainStationExecution.ts`
- Previously: `spawnTrain()` called `cluster.availableForTrade()` and
then `random.randFromSet(...)`.
- This built a new `Set` on the hot path.
- Now:
- Early-exit via `cluster.hasAnyTradeDestination(owner)`.
- Destination via `cluster.randomTradeDestination(owner, random)`.
Net effect:
- Less per-tick work and no per-spawn temporary `Set` allocations.
## Why this helps
Train spawning happens frequently and can become a hot path in large
games / large rail clusters.
Avoiding repeated allocations and reducing work inside `tick()` helps
keep frame/update time predictable.
## notes
- Trade rules are unchanged (`tradeAvailable(player)` still gates
eligibility).
- Destination selection remains random-uniform over eligible
`City`/`Port` stations that satisfy `tradeAvailable(player)`.
- `TrainStationExecution` now avoids calling `spawnTrain()` entirely
when `spawnTrains` is falsy (it was already guarded inside).

## Description:
This PR reduces server/client tick CPU spent on territory cluster
maintenance by:
- Cutting redundant work in `PlayerExecution.removeClusters()`
(largest-cluster bounding box reuse, fewer allocations in
`isSurrounded()` and `removeCluster()`).
- Making `calculateBoundingBox()` allocation-free per tile by switching
from `gm.cell(tile)` to `gm.x(tile)`/`gm.y(tile)` (it now only allocates
the two result `Cell`s, instead of 1 per tile).
## Commits
- `51de0a1b` core: reduce PlayerExecution cluster overhead
- `6d9d85c5` core: avoid Cell allocations in PlayerExecution
isSurrounded
- `346f6a8c` core(util): speed up calculateBoundingBox by avoiding Cell
allocations
## Notes
- This PR is intended to be behavior-preserving; changes are limited to
hot-path micro-optimizations.
- Follow-up opportunity: `calculateClusters`/flood-fill is now the top
hotspot; further wins likely come from reducing traversal work or
caching.

## Description
Optimize border-tile maintenance in `GameImpl` to reduce per-conquest
overhead.
Border tiles are updated whenever ownership changes; this PR trims
allocations and avoids unnecessary iteration in the hot path.
## Changes
- `src/core/game/GameImpl.ts`
- `updateBorders(tile)` no longer allocates an array of tiles; it
updates the changed tile and its 4-neighbors directly via
`forEachNeighbor`.
- `calcIsBorder(tile)` no longer calls `neighbors(tile)` / loops an
array; it checks the four cardinal neighbors via `x/y` bounds and
`ownerID`.
## Affected Functions
- `GameImpl.updateBorders(tile: TileRef)`
- `GameImpl.calcIsBorder(tile: TileRef): boolean`
- Call sites impacted by behavior/perf:
- `GameImpl.conquer(owner, tile)`
- `GameImpl.relinquish(tile)`

Maybe for v29.
In the 5M starting gold modifier games you can conquer a inactive player
(spawned but didn't do anything) and get their 5M gold.
Huge unfair advantage.
I think that even without the starting gold modifier you should not get
the gold of inactive players because its unfair.
I identify inactive players (spawned but didn't do anything) by checking
the attack stats.
I added a translation for the displayMessage "Conquered {name}, received
{gold} gold". Why was that not translated?
I added a new message "Conquered {name} (Inactive player, received no
gold)".

## Description:
Currently only the master process sends public lobby updates to clients.
This is not scalable since it could overload the master process.
In this PR, the master uses IPC to send public lobby info to all
workers. Then clients connect to a random worker to get public lobby
updates via websocket. This way clients never connect directly to the
master websocket.
The flow looks like this:
Every 100ms:
1. Master schedules a public game on a random worker if new games are
needed
2. Master broadcasts public lobby info to all workers (all public games
& num clients connected to each game)
3. Each worker responds to that update with the number of clients
connected to its own public games
4. Master then updates its public lobby state so it knows how many
clients are connected to each public game

Currently, when you send an alliance request to another player and it
gets rejected, but the same player sends you an alliance request back
during your alliance request cooldown, you cannot accept it via the
radial menu, you need to do that via the notification on the bottom

This is not consistent with when you receive an alliance request outside
of the cooldown.
This PR checks for incoming alliance request for the same player before
checking the outgoing request cooldown, therefore allowing you to accept
incoming alliance requests via the radial menu button even during
cooldown.

## Description:
Players wrongly assume that building a structure over an existing
railroad will connect it properly. What actually happens is that the
structure will connect on the network with its own railroad, even if the
new railroads are overlapping over the existing network.
To address this issue, this PR splits the overlapping railroad into two
segments when a structure is built over it, and inserts the structure as
a new node in the rail graph. It does not alter the rail network
visually because the same railroad tiles are used for the new segments.
Railroad tiles are not stored directly in the map, they exist only as
edges in the rail graph, so looking for nearby rails would be terribly
inefficient. To address that, this PR introduces a new `RailSpatialGrid`
class which indexes rails on a 4×4 grid, allowing fast spatial queries.
Alternative considered: removing overlapping rails and rebuilding them
from the new structure. It would visually modify the rail network, which
may be unexpected for the player.
It's still missing a visual indicator so the player knows that the
structures has been connected properly.
