The instance works out the recipe notification delta against the cleared
list the player had when the download started, but the save applied it
after the download restored player.force. A player whose force changed
kept notifications they had cleared elsewhere, and recipes only the old
force had dropped out of the failed list and were lost on the next
upload.
The download record now keeps the cleared list it sent. The save rebuilds
the stored list from it and the delta, then merges that against the
force the player has once the data is applied, as it did before #997.
Nothing extra goes over RCON.

controller.hosts is now a HostManager wrapping the hosts datastore, the
same way controller.users wraps the users datastore. It owns creating
hosts (moved from HostPairingManager), revoking them (moved from
ControlConnection) and signing and verifying host tokens (moved from
Controller, generateHostToken is renamed signHostToken to match
signUserToken).
UserManager gains verifyUserToken, replacing the copies of the user
token check in WsServer and routes. The WsServer copy accepted a token
without iat when the user had no tokenValidAfter; the shared check
always requires iat, which jsonwebtoken adds by default.

Review asked for the spectator to move freely while it waits. Only a jump
of more than 16 tiles from where it was last seen, or to another surface,
counts as a teleport and moves the restore location. The body place names
from #1156 become restore_location, keep_restore_location and
controller_taken.

A player waiting for player_sync data is a spectator who could walk away,
so restore_position teleported them back at the end. That also undid
teleports by other mods made during the sync, such as universal_edges
placing an arriving player.
The spectator is now pulled back on every tile change, and a jump of more
than 4 tiles or to another surface counts as another mod's teleport and
moves where the body comes back. A failed acquire that takes the body
keeps its place too.
Closes#908

"safe" suggested the data being written survives a crash, it only
guarantees the old file is either kept or fully replaced. The new name
says what it does. No alias, plugin API breaks are allowed in minor
versions and the 2.1 migration guide lists the rename.

Factorio encodes an empty Lua table as {}, so a player with no cleared
recipes sent {} with the download request. new Set({}) threw, the
instance dropped the recipe notifications from the download, and the
next upload replaced the stored list on the controller. An empty stored
list was dropped the same way. Decode both lists treating {} as empty.
While the host has no controller session, events between the instance
and the controller are dropped in both directions, and research_sync
only synced technologies on instance start. A technology finished during
the outage stayed unresearched on the controller and on every other
instance until the instance restarted.
On a new session the instance now runs the same technology sync as on
start, before taking the cluster queue. Contributions made while the
controller is unreachable are summed per technology and sent on connect
or resume, since progress from several instances can't be rebuilt from a
state sync that keeps the highest progress. A finish made while the
connection was dropped triggers the sync on resume too.
sync_technologies now runs while the game is running, so it skips
writing progress to a technology that finished after the dump.

Every RCON command makes an auto paused Factorio server run one tick, so
subspace_storage's 1 s inventory update and 5 s ping, plus a
statistics_exporter gather on every Prometheus scrape, kept a server with
nobody online running at about 1.3 ticks per second.
The instance now records the auto_pause server setting it was started
with and exposes autoPaused, true while that setting is on and no players
are online, along with an autoPauseChanged hook. subspace_storage skips
its timers while paused and sends a ping and inventory as soon as a player
joins. statistics_exporter gathers once after the game pauses and keeps
serving those values until it resumes.

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.

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.

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.

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.

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

The raise covered the whole gap between the serialized main inventory
and the main inventory with the armor restored, but only the bonus of
the armor's equipment arrives at the end of the tick. When the
destination force has a smaller character_inventory_slots_bonus than
the source, the rest of the gap never arrived and removing the raise on
the armor event dropped those slots on the ground. The raise is now the
equipment's inventory bonus minus what the grid already applies, at
most the gap, and the slots past it overflow into a corpse as without
the raise. Factorio 1.1 has no inventory bonus equipment and gets no
raise.

on_player_armor_inventory_changed for the restored armor is raised at
the end of the download's tick, after the inventory bonus of the armor's
equipment applied, so the raise is removed there instead of in the next
tick's on_tick. The raise is only made for armor with a grid, as the
event needs the armor to be restored.
A player leaving on the tick of a download no longer has the raise
removed from the character first, which shrank the main inventory
before the bonus applied and spilled the extra slots. The raise is
taken off the uploaded inventory bonus instead.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The inventory bonus of equipment in the armor's grid (toolbelts) is
applied by the engine on the tick after the armor is inserted. The main
inventory was restored in the same tick, so the items of every slot past
80 plus research plus the armor's own bonus did not fit and were put in
a corpse: legendary mech armor with legendary toolbelts left 2125 of
2330 slots in the corpse.
The armor is now restored first, the character's inventory bonus is
raised to fit the saved main inventory, and the raise is removed again
on the next tick, or before an upload if the player leaves first.
