Lib and plugins import Node.js modules such as events and buffer, which
the build swaps for browser packages. Vite resolves an aliased import
from the importing package, and pnpm only lets a package see its own
dependencies, so the polyfills had to be dependencies of lib.
Resolve them from web_ui with a small resolver plugin instead, also
used by the dependency optimizer. Hosts no longer install the browser
packages, and plugins get the same polyfills webpack gave them.

Replace ESLint, typescript-eslint, eslint-plugin-node and the flat
config helpers with vite-plus, which runs Oxlint for vp lint. The rules
are carried over from eslint.config.mjs by @oxlint/migrate into the lint
section of the root vite.config.ts. The formatting rules ESLint
deprecated run as @stylistic rules through Oxlint's JS plugin support,
and disable comments naming them are updated to the @stylistic names.
@stylistic understands TypeScript syntax that the core rules skipped,
so the autofix adds missing semicolons and spaces in type literals and
aliases. Leading | and & in multiline types stay where they were.
Oxlint's node/no-sync also reports identifiers ending in Sync that are
not calls. The test helper techSync is renamed and the two other names
are ignored.

Replace webpack and Module Federation with Vite 8. The controller build
emits one entry per shared module (lib, web_ui, typebox, antd, react,
react-dom, react-router) and lists them in manifest.json. The controller
turns that into an import map in index.html, and plugins are built as
ES modules that import the shared modules by name and are loaded with
import().
The shared Vite setup lives in @clusterio/web_ui/vite.mjs. Plugins use
clusterioPlugin(), which exposes index, package.json and web/index under
the same keys the webpack template used. The --dev and --dev-plugin
flags now run the Vite dev server in middleware mode with hot module
replacement.
Browser polyfills move from web_ui to lib, which is the code that needs
them, and lib sets the process and Buffer globals itself.

* Keep error classes across links
Error responses now carry the registered name of the thrown error's
class, and the requester rejects with an instance of that class instead
of a generic RequestError. Error classes are registered like message
classes, and plugins list their own in `errors`.
RequestError is replaced by a hierarchy following the HTTP status codes:
ClientError (ValidationError, ForbiddenError, NotFoundError,
TimeoutError, ConflictError) and ServerError (InternalServerError).
PermissionError is PermissionDeniedError and the config errors
InvalidValue, InvalidField and InvalidAccess gain an Error suffix.
Link logs only errors whose class is not registered. These arrive on the
other side as InternalServerError with the original message and stack,
so an error forwarded through the controller is logged once, where it
was thrown.

* Add UnavailableError and keep the PermissionError name
Host not connected, host shutting down and instance not running are
now UnavailableError (503) instead of ConflictError. The request error
migration notes move to a new 2.1 guide, since this ships in 2.1.

Add a LogEntry type for log entries sent over links and returned by
log queries. It names the fields every entry has (level, message,
timestamp) and leaves the rest as unknown.
The console now prefixes each line with the entry's time in the
browser's local time zone, which makes it possible to tell when an
error happened after the fact.

Notes in the web UI now render through ReactMarkdown. A mention like
@instance/778528005 or @user/cooldude2606 turns into a link to that
resource's page, labelled with its name if the client has it and the id
otherwise. The stored note keeps the mention as written. Line breaks
are kept as hard breaks so existing plain text notes look the same.

FactorioServer.fromOptions finds the Factorio install and generates the
RCON password before constructing, so _version and _dataDir are never
null and setTargetVersion and init are gone. checkForUpdates is now a
module function called before fromOptions.
Instance.fromConfig resolves the version, downloads Factorio if needed
and builds the server, then constructs the instance with it. It runs
before the instance is connected, so the starting and stopped statuses
and the version requests go through the host link. FactorioVersionsRequest
and LatestReleasesRequest now accept host as a source, and the host
tracks starting instances so a second start during a download is
rejected. Plugin loading stays a separate loadPlugins step after the
instance is connected.

Controller.fromConfig and Host.fromConfig now take the config, then the

Controller.bootstrap and Host.bootstrap returned constructor arguments
that the caller had to spread into new Controller/Host, and
DatastoreProvider.bootstrap did the same for datastores. They are
replaced by Controller.fromConfig, Host.fromConfig and
KeyValueDatastore/SubscribableDatastore.fromProvider, which load the
data and return the finished instance.

Fall back to copying on any link error except EEXIST, since filesystems
without hard links report it with several codes (EISDIR on exFAT under
Windows, ENOSYS on some FUSE mounts). Rename now goes through the same
move so it also gets the fallback and the rollback. Only report a
missing source save on transfer when the source is actually missing.

Instance dir and save names are tried without a retry cap, as on master
and in downloadFile, so an 11th instance named "New Instance" still gets
a folder.
Moves fall back to an exclusive copy when hard links are unavailable
(EXDEV, EPERM, ENOTSUP), and remove the new target if the source can't
be unlinked, so a failed move leaves no duplicate.
Local transfers keep appending .zip to the target name, as
findUnusedName did.
The copy auto-rename test now checks that the existing target save is
left untouched.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The name it returns may already be taken by a concurrently running process
by the time the caller uses it. Callers now try the name and retry with a
-2, -3, ... suffix on EEXIST instead.
Save transfers previously renamed with fs.rename, which silently overwrites
a save that appears at the target, and copied without COPYFILE_EXCL. Moves
now use link + unlink like save rename does, and copies pass COPYFILE_EXCL,
so both fail with EEXIST rather than overwrite.
Supersedes #880.

Factorio 2.1.18 removed PollutionSettings::max_pollution_to_restore_trees,
but readPollution still read it for every version, so every map setting
after it was read 9 bytes late: enemy_attack_pollution_consumption_modifier
came out as garbage, the enemy_evolution factors shifted by one field and
enemy_expansion.enabled and both expansion distances came out null.
Read the field only for strings older than 2.1.18. Add modified_v2_1_17
and modified_v2_1_18 fixtures generated with headless 2.1.17 and 2.1.18
from the modified 2.1 settings (base game only), unit tests asserting
their full decoded output, and use the 2.1.18 string for the
load-scenario integration test on 2.1.18 and later.

Node 26.12.1 (CVE-2026-105481) makes the http agent check a kept-alive
socket for pending data before reusing it. The queued request now sees
the server's EOF, opens a new connection to the closed server and gets
ECONNREFUSED instead of ECONNRESET. Either way the request is dropped.

The download a join forces after dropping a copy that took the body found the
player already a spectator, so it kept the spectator's place and restored the
character there. It now takes the surface, position and vehicle the dropped
copy kept.

The leave handler skipped the upload for any active download, including a
prefetched copy no join had confirmed, which has replaced nothing here. Newer
local data, such as after a failed upload whose retry the join cleared, was then
never uploaded. Only a real download skips it now; a copy whose join took the
body still uploads nothing through sync_in_progress.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A copy confirmed at an earlier join has replaced the body with a spectator.
If a later join drops it (another controller run) while the generations match,
the join kept the local state: a spectator with no body, uploaded on the next
leave. Download instead. A newer copy replacing a held one keeps where the
body stood, so the replacement still counts as having taken it.

An admin import or delete bumps the stored data's epoch and can start the
generations over, so a copy held from before it must not apply. The prefetch
carries the epoch like the token, and a held copy is used only when it matches
the acquire reply's.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
An instance with older data can upload the generation a save already holds, and a prefetch of it then overwrote that
save's newer state. A join now drops a prefetched copy unless the ordinary download check says the data is needed.

Chunks of an earlier controller run's copy still in flight could land in a newer run's copy of the same generation. Every chunk now carries the token, and the scenario ignores a chunk whose token differs from its record's.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
If the controller crashes after sending generation N but before saving it, the destination keeps that prefetch while the controller restarts at N-1, and another instance can then upload different data as generation N. The controller now picks a random token per run, sends it with every prefetch and acquire reply, and the scenario applies a held copy only when its generation and token both match, and lets a new run's copy replace one with another token.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A prefetched copy is sent without the save's list of cleared recipes, so
its delta had only add, and a recipe cleared on the destination but not
in the stored list stayed cleared where a download would give it its
notification back. Without a current list the instance now sends the
whole stored list marked full, and the save gives the recipes it has
cleared that aren't in it their notification back, as a download's
remove does.

player_sync.prefetch_inventory holds a copy sent ahead in active_downloads
and finished_downloads, for a player who is offline or doesn't exist on
the destination, with the components its first chunk names. Chunk 1
refuses a player who is online, a download in progress, a stream of the
same or a newer generation and a finished copy of a newer one; a finished
copy of the same generation is replaced. At the acquire reply a copy is
used only when the reply is acquired with its generation and its
components are the ones the scenario syncs now. The player is then
switched to spectator as a download does and the copy is applied, at once
or at its last chunk. Otherwise the copy is dropped and the join
continues as before.

A plugin that moves a player calls remote.call("player_sync",
"set_destination", player_name, instance_id) before connect_to_server.
It only records the destination. Every leave clears it, and a leave
that uploads with reason switching_servers adds it to the upload as
destination_instance_id. The README describes it for plugin authors.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The instance passes destination_instance_id from a leave upload on as
destinationInstanceId, and sends a PrefetchEvent's data to
player_sync.prefetch_inventory in RCON chunks, using the download's
chunk loop. As for a download, the data is stripped by the instance's
own player_sync.sync_* options and the components go with the first
chunk. A non-empty reply means the save refused or ignored the copy and
stops the transfer.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
An upload can carry destinationInstanceId. Once the upload is stored,
the controller sends the stored data, the upload merged with its copy,
in a PrefetchEvent to that instance, if it is another running instance
with player_sync enabled. No lock is taken or released. A failed send is
logged and doesn't fail the upload.

A QueueEvent arriving in the same socket read as a QueueSyncRequest reply is

The drawer actions move to its header as Export, Import and a trash
icon for Delete. Import and Delete are disabled while an instance
holds the player, since the stored data is out of date until it
uploads. The drawer also shows color and cheat mode.
Inventory tables get title case names, pagination at 10 rows, item
search, sorting and quality icons. The player list shows force with
a filter instead of generation, and the database stats use
Descriptions without the largest entry.

Imports no longer accept the cutscene controller, which needs waypoints
to restore. Logistic filters and the basic item stack fields now have the
types and limits Factorio enforces, and the inventory summary skips
malformed items and counts repeated exported items once instead of
expanding them.
Lua's JSON loses precision past 2^50, so a generation there could no
longer be counted up and uploads were discarded. Imports now start over
from generation 1 when the stored or imported generation is at that limit.
Instances holding a copy from another epoch take the stored generation
instead of keeping their own higher one when there is no data to download.

research_queue_api is compat.version_ge("2.0.56"), named like player_sync's version checks, so it doesn't read as a
