## Description:
I hope we can get this into v30?
The nation count is configurable now, just like the bot count.
Replaced the "Disable Nations" toggle with a nations slider (0–400) in
SinglePlayer and Host Lobby modals.

/>
Public games are staying exactly the same, this is just for singleplayer
and private lobby fun.
Youtubers could play HvN against 400 nations, for example.
Singleplayer enjoyers no longer have to play against 1 nation in HvN,
they can freely choose.
`GameConfig.disableNations: boolean` got replaced by `nations: number
(0-400, optional)`
`undefined` = map default,
`0` = disabled,
number = custom count
Nations slider defaults to the map's nation count, shows "(MAP DEFAULT)"
label when unchanged
Compact map toggle reduces nations to 25% when at default, restores when
toggled off (just like we already do with bots)
The nation count for HvN no longer automatically matches the human count
in singleplayer and private games, only in public games.
**What if there aren't enough nations configured for the map?**
We just use the HvN logic (Generate random nations)
### Warning
**This infra PR also needs to get merged:
https://github.com/openfrontio/infra/pull/263
Otherwise players can set 0 nations and get achievements.**

Reverts openfrontio/OpenFrontIO#3320
doesnt do what it says
The #3320 description claimed it “resolves a performance parsing
penalty” and fixes “non-square sprite” scaling/ghosting issues.
In reality, the code change was limited to:
* **clearRect**: switched from clearing a `clearsize x clearsize` square
(`clearsize = sprite.width + 1`) around `lastX/lastY` to clearing a
**(sprite.width+2) x (sprite.height+2)** rect around **rounded**
`clearX/clearY` (with an extra 1px pad via `-1/+2`).
* **drawImage**: changed a single call’s destination height from
`sprite.width` → `sprite.height`.
### Why revert
For unit rendering, sprites are square, so the drawImage change is a
no-op in practice, and the main effect was **clearing more pixels per
frame**. Any theoretical gain from rounding coordinates is speculative,
and is outweighed by the increased clear area/overdraw.
## Description:
Resolves#3285. As discussed on Discord.
However, in at least one instance "Tribes" feels a bit off: in Humans vs
Nations, team "Tribes" feels as human too while they are just bots.
This PR changes Bots to Tribes outwardly by
- Changing default EN translation.
- Changing (untranslated) alt text in PlayerPanel.
- To change "Team Bot" into "Team Tribes" too in PlayerInfoOverlay and
TeamStats (team leaderboard in-game), translate team names in there from
now on too.
- This way we also fix a bug where team names were not translated yet in
there. To add to that fix, also translate team names in LobbyPlayerView
in the same way. For this we re-use the existing
getTranslatedPlayerTeamLabel function from GameLeftSideBar by moving it
to Utils.
- No translation key was present yet for Humans and Nations teams, so
added those to now be used in PlayerInfoOverlay, LobbyPlayerView and
TeamStats for completeness.
- No internal code changes so nothing breaks.
**BEFORE (showing old team name Bot and also that team names weren't
translated yet in TeamStats)**


**AFTER** (translations in Dutch only shown as proof here, did not
include nl.json in the PR)

Begins work on #3207
## Description:
This PR is the first optimization slice for #3207: it removes O(n)
render lookups in `StructureIconsLayer` by replacing array-first render
state with a unit-id keyed map, and tightens hot-path execution to
reduce per-tick allocations.
### What changed
- Refactored render state from array-first to `rendersByUnitId:
Map<number, StructureRenderInfo>`.
- Replaced O(n) lookup/delete paths with O(1) `Map#get` / `Map#delete`.
- Replaced `seenUnits` object-identity tracking with `seenUnitIds:
Set<number>`.
- Removed `tick()` array/closure chain (`map(...).forEach(...)`) and
switched to index-based loop.
- Reduced ghost-path allocation pressure by reusing a layer-level `Set`
for connected ally IDs instead of allocating `filter` + `map` + `new
Set` per ghost query.
- Added dirty-flag caching for structure visibility focus
(`visibilityStateDirty`) so expensive visibility-state scans recompute
only when toggles change.
### Performance validation (before/after)
Benchmark added: `tests/perf/StructureIconsLayerLookupPerf.ts`
Command:
`npm run perf`
Observed result:
- `StructureIconsLayer BEFORE (array O(n) lookup/delete) x 0.33 ops/sec
±13.28%`
- `StructureIconsLayer AFTER (unit-id map O(1) lookup/delete) x 95.65
ops/sec ±2.46%`
- Fastest implementation: AFTER (unit-id map)
#### Profiler screenshots are too noisy to be useful for such a focused
change
### Verification
- `npx tsc --noEmit` ✅
- `npx eslint src/client/graphics/layers/StructureIconsLayer.ts
tests/perf/StructureIconsLayerLookupPerf.ts` ✅
- `npm run perf` ✅

Introduces Passage, an island filled thin map (like Amazon River but

really fun gameplay. I playtested with 3 friends a number of times and
it's great in pretty much all the modes. Naval gameplay on this map is
particularly fun since some islands in the center basically hold the
choke points on trade ships passing from one side to another, making
them hotly contested territory.

## Description:
This PR resolves a performance parsing penalty in the `UnitLayer`
rendering loop by fixing two issues with non-square sprites:
1. `drawImage` was incorrectly using `sprite.width` for both width and
height, causing aspect ratio squashing and forcing the browser to
perform a scaling operation on the image instead of hitting the canvas
fast-path. It now correctly uses `sprite.height` for the vertical
dimension.
2. `clearUnitsCells` was previously configured to only clear a square
grid (`clearsize`) based solely on width, meaning taller sprites would
leave visual artifact "ghosts" on the map. The clearing bounds have been
corrected to leverage discrete `sprite.width` and `sprite.height`.
Additionally, these values are wrapped in `Math.round()` prior to offset
calculation to prevent subpixel anti-aliasing CPU penalties during
`clearRect`.

## Description:
This PR consolidates ad hoc platform/environment/viewport detection into
a single shared utility. It is scoped to this refactor only, and serves
as groundwork for the mobile-focused feature work planned for the v31
milestone.
### What changed
- Introduced a shared `Platform` utility centralising:
- OS detection (with `userAgentData` + UA fallback)
- Electron environment detection
- Viewport breakpoint helpers (`isMobileWidth`, `isTabletWidth`,
`isDesktopWidth`)
- Replaced duplicated inline checks across client files with the shared
API.
- Normalised Mac detection to derive from the consolidated OS logic
rather than a separate regex.
### Why
- Multiple client files each independently ran `navigator.userAgent`
regexes or copy-pasted `isElectron` logic — this unifies all of that.
- Puts a stable, tested abstraction in place before v31 mobile work
lands, so mobile feature branches have a consistent surface to build
against.

## Description:
Adds two new public game modifiers for variety and improves compact map
eligibility for team games.
### New Modifiers
**Hard Nations (`isHardNations`)**
- We need this modifier for HvN, because medium nations are easier now
(will result in a much higher human winrate)
- In a discord discussion we concluded that HvN should generally be
easier (higher winrate than 50%, so players are less frustated)
- Thats why only 20% of HvN games have the hard nations modifier (for
now)
- For PvPvE enjoyers, the modifier is also active in FFA games => (Only
2.5% chance, and 1 ticket in `SPECIAL_MODIFIER_POOL`)
**25M Starting Gold (`startingGoldHigh`)**
- Some people in the main discord wanted this modifier, and it will
result in crazy games
- Rare special-only modifier (1 ticket in pool); mutually exclusive with
5M starting gold via `MUTUALLY_EXCLUSIVE_MODIFIERS`
- Disables nations (they lack PVP immunity, so 25M gold doesn't work
well with them)
- Excluded from HumansVsNations games (since it disables nations)
- Spawn immunity set to **2 minutes 30 seconds** (vs 30s for 5M gold),
so people can spend the gold and prepare
### Other Changes
- **Improved `supportsCompactMapForTeams`**: Replaced the hard `smallest
>= 50` land-tile cutoff with a per-team-config calculation that
simulates worst-case compact player count and checks every team gets at
least 2 players.
- **HvN spawn immunity**: Always 5 seconds in both regular and special
lobbies (to get rid of a confusing PVP immunity HeadsUpMessage in 5M
starting gold games)
- **Regular public lobby random spawn modifier probabilty**: Reduced
from 10% to 5% (Because of the new modifier, so there aren't too many
modifiers in non-special-lobbies, should only occur sometimes there)
- Rebalanced `SPECIAL_MODIFIER_POOL` a bit

## Description:
This PR fixes an exploit that allows the player to request alliances to
Nations, mostly in impossible mode, during spawn phase, with high
chances for it to be accepted due to troop count parity.
Nations now reject alliance requests during the spawn phase.
`GameImpl.executeNextTick()` initializes ALL pending `unInitExecs` in
one batch on the first post-spawn tick ( `numSpawnPhaseTurns() + 1` ).
So every alliance request submitted during spawn phase is guaranteed to
be created with `createdAt = numSpawnPhaseTurns() + 1` on the very first
post-spawn tick.
Therefore, we check for alliance requests created on the very first
post-spawn tick and reject those.

Optimally maps have letters A-J (just like in the Battleships board

2 letters so as to not have too many number columns. This feature
overall can be toggled via the settings menu.

## Description:
Removes the client-driven heartbeat loop and switches worker tick
execution to a worker-owned drain scheduler with batched game update
delivery.
## Why
The previous flow required the client to send a `heartbeat` every
animation frame just to keep the worker progressing turns. That had two
costs:
1. Simulation progress was coupled to browser frame cadence.
2. Catch-up periods produced many single `game_update` messages,
increasing message overhead and main-thread wakeups.
## What Changed
### 1) Remove heartbeat protocol
- Deleted `heartbeat` from `WorkerMessageType`.
- Removed `HeartbeatMessage` from `MainThreadMessage`.
- Removed `sendHeartbeat()` from `WorkerClient`.
- Removed the `requestAnimationFrame` keep-alive loop in
`ClientGameRunner`.
Files:
- `src/client/ClientGameRunner.ts`
- `src/core/worker/WorkerClient.ts`
- `src/core/worker/WorkerMessages.ts`
- `src/core/worker/Worker.worker.ts`
### 2) Add batched worker-to-client updates
- Added `game_update_batch` message type and `GameUpdateBatchMessage`.
- Worker now emits one batch message containing multiple tick updates.
- `WorkerClient` handles `game_update_batch` by replaying updates to the
existing callback in order.
Files:
- `src/core/worker/WorkerMessages.ts`
- `src/core/worker/WorkerClient.ts`
### 3) Move tick draining into worker
- Added a scheduler (`scheduleDrain`) and drain loop (`drain`) in
`Worker.worker.ts`.
- On each `turn` message, worker enqueues turn and schedules drain.
- Drain executes up to `MAX_TICKS_BEFORE_YIELD = 4` ticks per cycle,
then yields with `setTimeout(..., 0)`.
- Tick updates are collected into a batch and sent once with
transferables:
- `packedTileUpdates.buffer`
- `packedMotionPlans.buffer` (when present)
- If backlog remains, drain reschedules itself.
File:
- `src/core/worker/Worker.worker.ts`
## Behavioral Notes
- No server protocol changes.
- Ggame update callback contract remains the same (still receives one
`GameUpdateViewData` at a time in order).
- Ordering is preserved: `WorkerClient` iterates batch entries in
sequence.
- Error updates are still filtered from update delivery in the worker
batch path (same effective behavior as before for normal update flow).
## Expected Impact
- Fewer `postMessage` calls during backlog and burst turn delivery.
- Lower message overhead and fewer main-thread interrupts.
- Less dependence on UI frame timing for worker progress.
- Better catch-up stability due to explicit periodic yielding.
## Risk Areas
- Drain scheduling edge cases (re-entrancy / lost wake-ups).
- Mitigated with `drainScheduled`, `draining`, and `drainRequested`
flags.
- Larger per-message payloads due to batching.
- Bounded by `MAX_TICKS_BEFORE_YIELD`.
- Any assumptions in downstream code about receiving only `game_update`.
- Handled by adding `game_update_batch` support in `WorkerClient`.

## Description:
Reduce per-step `Unit` update traffic by shipping packed motion plans
and letting the client advance plan-driven units locally.
Changes:
- Add packed motion plan records (`packedMotionPlans?: Uint32Array`) to
game updates and transfer the buffer worker -> main.
- Introduce `src/core/game/MotionPlans.ts` (schema + pack/unpack) for
grid + train motion plans.
- Extend `Game` with `recordMotionPlan(...)` and
`drainPackedMotionPlans()`, and implement buffering/packing in
`GameImpl`.
- Treat units with motion plans as “plan-driven”: suppress per-tile
`Unit` updates on `move()` and advance positions client-side.
- Emit motion plans from executions:
- `TradeShipExecution`: record/update grid motion plans and `touch()`
when changing target after capture.
- `TransportShipExecution`: record initial plan and update it when

NOTE: Applies to current main / beta version. Needs to be included in
v30.
When a player clicked "Renew Alliance", the `AllianceExtensionUpdate`
broadcast caused both players' renewal prompts to be removed, even the
one who hadn't yet acted. This happened because
`onAllianceExtensionEvent` called `removeAllianceRenewalEvents`
unconditionally on every client.
This PR fixes the behavior by calling `removeAllianceRenewalEvents` only
for the player that executed the action.

New version of the #2789 PR that is cleaner after changes made to old
pathfinding logic.
Adds logic to troop transport retreat behaviour which retreats a
transport to the closest owned tile instead of the source. Now if no
shores are detected (you lost all your shoreline while the transport was
out) we handle the return case same as if the original source was no
longer your territory.

Preparation for nuke wars, for v30.
Next PR will be adding the nuke wars modifier for public games, but
Wonders https://github.com/openfrontio/OpenFrontIO/pull/3224 needs to be
merged first to avoid merge conflicts.
### 1. Disable boats setting
It's possible to disable `UnitType.TransportShip` now. Because they are
not needed in nuke wars and can even be annoying.

### 2. Team spawn zones for random spawn
Maps can have `teamGameSpawnAreas` in their json file now.
Spawn areas are currently active if
- a supported map is chosen (Baikal Nuke Wars or Four Islands)
- a supported team size is chosen (2 teams on Baikal Nuke Wars or 2/4
teams on Four Islands)
- random spawn is enabled

## Description:
updates the Performance Overlay to be more usable
(draggable/resizable/scrollable), adds tick-level metrics (TPS +
per-layer tick timings), and reduces overhead when the overlay is
hidden.
### UI/UX
- Overlay layout updated to a fixed, pixel-positioned panel (default
near top-left) with a dedicated drag handle.
- Overlay is touch-draggable (pointer events) and remains usable on
small viewports via internal scrolling.
- Overlay width is resizable with a right-edge handle; width is clamped
to viewport bounds.
- Render/tick layer breakdown sections are collapsible, with headers and
“last tick” summaries.
### New metrics
- Adds TPS reporting:
- Current TPS (ticks in the last 1s).
- Average TPS over the last ~60s, computed using elapsed time so it’s
accurate before a full 60s passes.
- Adds per-layer tick profiling (“Tick Layers”) alongside render
profiling (“Render Layers”).
- Adds “render-per-tick” metrics so render-layer costs can be understood
per simulation tick (frames + per-layer totals).
### Performance / overhead
- Avoids profiling overhead when the overlay is hidden:
- `GameRenderer` only calls `FrameProfiler.clear()/consume()` and
per-layer `start/end` when profiling is enabled.
- Tick-layer duration tracking is only collected when profiling is
enabled.
### Settings plumbing
- `UserSettings` now dispatches a `user-settings-changed` `CustomEvent`
on `set()` / `setFloat()`.
- The overlay listens for `settings.performanceOverlay` changes so
visibility stays in sync even when toggled outside the overlay.
## Implementation notes (by file)
- `src/client/graphics/layers/PerformanceOverlay.ts`
- Adds TPS tracking using a timestamp ring + moving heads (1s / 60s).
- Adds UI state for collapsibles, drag + resize pointer tracking, and
new breakdown models:
- Render layers: EMA avg/max + per-tick render aggregation.
- Tick layers: EMA avg/max + last-tick durations.
- Copy-to-clipboard snapshot now includes TPS, tick layers, and
render-per-tick last-tick details.
- `src/client/graphics/GameRenderer.ts`
- Gates render-layer profiling behind `FrameProfiler.isEnabled()`.
- Accumulates per-render-layer timings across frames and publishes them
once per tick via `updateRenderPerTickMetrics(...)`.
- Measures tick-layer durations (per layer `tick()` call) and publishes
them via `updateTickLayerMetrics(...)`.
- `src/core/game/UserSettings.ts`
- Adds `emitChange(key, value)` to dispatch `user-settings-changed` to
`globalThis` (best-effort).
- `resources/lang/en.json`
- Adds/updates `performance_overlay.*` strings for TPS and the new
render/tick layer sections.

## Description:
Please merge for v30 if possible.
Use .find instead of .filter for tradeShipSpawn since we're only looking
for the first (if any) port found at the given tile anyway.
Also just return targetTile instead of getting porr.tile() because
targetTile is tile we found the port on.
Also use no intermediate const, just return right away based on outcome
of units.find.
Found when working on PR #3220. But tradeShipSpawn is out of 3220's
scope since it won't be called by playerImpl buildableUnits() anymore,
it should and will be only ever used by TradeShipExecution via
playerImpl canBuild().

Can we maintain a one-minute game creation rate with three times as many

I don’t think so - we should allow more time for players to join.
It still shouldn’t bore players, since they can also join the special
mix lobby. That lobby includes both FFA and team games and fills more
quickly due to the higher frequency of compact-map matches (the Wonder
PR https://github.com/openfrontio/OpenFrontIO/pull/3224 needs to be
merged for that).

- **News notification dot (desktop + mobile)**: Added a red pinging dot
on the "News" nav entry that appears when a new version is released. The
current app version is saved to localStorage (`newsSeenVersion`) on
first visit. On subsequent visits, if the version has changed, the dot
appears. Clicking "News" dismisses it by updating the stored version.
- **Mobile Store**: Replaced the static "NEW" text badge on the Store
nav item with a red pinging dot (matching the desktop navbar style). The
dot is conditionally shown based on cosmetics hash changes tracked in
localStorage, and dismissed when the user clicks Store.
- **Help dot on mobile**: Added the yellow help dot (already present on
desktop) to the mobile navbar for consistency, shown for users with
fewer than 10 games played.

## Description:
Introduces a dedicated `factoryValue()` scoring function for AI factory
placement, replacing the generic `interiorStructureValue()` previously
shared with cities and missile silos.
Scoring criteria:
- High elevation and spacing from other factories (unchanged from
city/silo logic)
- Rail connectivity: bonus per distinct rail cluster reachable within
`trainStationMaxRange`, weighted by trade gold potential — allied
clusters score highest (1.0), team/neutral clusters score ~0.71, own
clusters ~0.29 (based on `config.tradeGold()` values). Based on
difficulty
- Cluster deduplication: connecting to the same cluster multiple times
does not inflate the score
- Embargoed and bot neighbors are excluded; all other non-embargoed
neighbors are included
The result is that the AI tends to place factories where they can bridge
separate rail networks or connect to high-value trade partners, rather
than deep in its own interior.
### EDIT
Added a dedicated `cityValue()` scoring function that takes into account
the connectivity score. This allows placement of cities in a
"factory-aware" way, while also enforcing spreading structures (we want
the network to grow, not a cluster of cities and factories all
together).

The master set lobby start times on creation, which caused an issue if
the previous lobby filled up and started before its timer ran out, the
next lobby would have its timer set too far back. For example, if lobby
time is 60 seconds, and the first lobby fills up after 10s, the
subsequent lobby would have its timer set for 110 seconds (60+50).
Instead we have the master set the lobby start time only when it is next

## Description:
Adds an additional API endpoint to the server for health, using the
master lobby service as the health metric. The master lobby service is
considered healthy if the lobby service has started (i.e. it had enough
ready workers to start), and the current amount of ready workers is more
than half of the desired number.
This means that we won't show as healthy until all the workers start,
and then we will continue to show as healthy even if a few workers
crash, as long as at least more than half are still running. Any less
than that, and the service becomes unhealthy.
This also is set to "no cache" in the nginx config. This is to ensure
that any checks of the server health show the true value, and cannot
show false/stale data served by nginx, cloudflare, or anything else.

### SAM Overwhelming (`NationNukeBehavior.ts`)
On Impossible difficulty, nations can now destroy enemy SAMs by
overwhelming them with coordinated atom bomb salvos. When no good nuke
target is found (all trajectories intercepted by SAMs), the nations
will:
- Identify the easiest enemy SAM to destroy (lowest level first)
- Calculate the total interception capacity of all covering SAMs and
send enough bombs to overwhelm them (+1 extra per 5 needed to account
for enemy building more SAMs during flight)
- Plan launches in NukeExecution's Manhattan-distance silo order,
tracking which silos have interceptable trajectories (wasted bombs)
- Use a sliding window over parabolic flight times to find the best
cluster of bombs that can arrive within half the SAM cooldown window
- Compute per-bomb wait ticks to synchronize arrivals from silos at
different distances
- Skip launching if a salvo is already in flight
- Upgrade the best SAM-protected silo when silo capacity is
insufficient; wait and save gold when only gold is lacking

### 2-Player Endgame Handling (`NationNukeBehavior.ts`)
- On Hard/Impossible with only 2 players remaining,
`findBestNukeTarget()` directly targets the other player (bypasses all
priority logic)
- `getPerceivedNukeCost()` returns actual cost (no MIRV saving
inflation) when only 2 players are left
### SAM Build Rate (`NationStructureBehavior.ts`)
- Reduced SAM perceived cost increase per owned from 1.0 to 0.5, so
nations build more SAMs
### Island Attack Variety (`AiAttackBehavior.ts`)
- `findNearestIslandEnemy()` now collects up to 2 reachable candidates
and has a 33% chance to pick the second-nearest, adding variety to boat
attack targeting

## 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`.
