The nil check burn down added guards which turned out redundant once
the surrounding annotations landed. `_has_handlers` is set to true when
the first handler registers, so it is a boolean rather than the literal
false it was inferred as.

`assert` returns every argument it is given, so `return assert(x, msg)`
was leaking the message as a second return value.
`get_tile` is documented as taking x and y. The async function class
declared `@operator call` with no parameters, which made every async
call look over supplied.

Guards now cover the statements that follow them, and a couple of reads
are restructured so the narrowing survives.

The api documents both as a union with a positional array because both
are accepted as input, which makes every read of `.x` or `.left_top`
optional. Everything read back from the game uses the named form, so
the positional variant is removed and we now always write it that way
too.
The spawn area config offsets and the mine depletion search areas were
the only positional writes left, and apply_offset no longer needs its
fallback.

spawn_area accepts both position forms on purpose, so it asserts that
one of the two is present rather than narrowing the type.

Color.struct leaves every channel optional, so the rainbow command
declares its own fully populated colour.

Rows and selectors are created alongside the machine selector, so they
exist for anything already in the table.

A union of table types makes every lookup optional. Separate index
signatures on one class say the same thing without the nil.

Values read back from the game always use the named members, so they
are narrowed once where they enter a function rather than at each use.
`LuaControl.force` is a ForceID union, so reading a force only method
off it needs the cast the rest of the repo already uses.

`Roles.new_role` returned the result of `error`, which made it nullable,
and `set_permission_group` returned nil for an unknown group, which
broke the config chain with an index error rather than saying so.
Positions and bounding boxes read back from the game always use the
named members, so they are narrowed once where they enter a function.

Locals declared ahead of an assignment inside a callback were inferred
as nil at every use site.
The role event handlers are given a class so the table is not unified
with the other module handler tables.

`loadstring` was removed in Lua 5.2, `load` takes a string the same way.
Warp gui child lookups are optional, so they use the same assert the
rest of the repo does.

`LogisticFilter.signal` became `value` in 2.0, so the clear loop broke
on the first slot and outdated signals were left behind.

Autofill stores the whole per entity map against a player.
The readme container is called as a define, so it needs the overload
the other element classes carry.

`_display_data` is a cache keyed by force name, not a single record.
The auto complete accumulator starts empty, so its fields are optional.
Game commands have no usage beyond their own help text.

`config.temp_warning_limit` does not exist, the warnings config defines
`script_warning_limit`, and the locale expects it as `__3__/__4__`, so
the command was printing nil.
map_tags is keyed by the force name joined to the tag number, and
custom_color is the Color union.

emmylua only parses the inline cast as `--[[@as T]]`, the spaced form
`--[[ @as T ]]` is treated as a plain comment, so all 149 of them were
doing nothing.
LuaGuiElement.style is a union because a style name can be assigned to
it, so reading it back needs the cast.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`data` on an element is the GuiData store keyed by element, not the
value being stored.

The prune loop shadowed its own parameter, so `silo_data[unit_number] =
nil` wrote into the entry instead of removing it from the table.
`unit_number` is optional on LuaEntity but always set for a silo. Note
that `--[[ @as ]]` does not narrow for an index expression, only
`@cast` does.

emmylua deserialises an unknown diagnostic code to a catch all that
matches no checker, so every `invisible`, `nil-check` and
`global-element` suppression was silently doing nothing. Renamed to the
emmylua codes. `name-style-check` has no equivalent and is dropped, it
was already disabled under luals.
The `get_tile` suppressions referenced an api typedef bug from 2024
which no longer reproduces.
need-check-nil is deferred rather than disabled on merit: a third of the
407 findings come from MapPosition and BoundingBox being aliased as
`struct|[double, double]`, so every `entity.position.x` reads as
possibly nil. The rest need per site knowledge of runtime invariants.

The aabb functions all index the named members, so passing the
shorthand [MapPosition, MapPosition] form would error at runtime. The
annotations now say so.
emmylua requires a type argument on a generic alias, luals did not.

Classes contributed to by more than one file now carry the `partial`
attribute. trains.lua declared its command as `ExpCommand_Artillery`,
which was a copy paste.
`Color.0` and `MapPosition.0` became `.struct` in fmtk 2.1.6.
emmylua rejects `@type` on a function statement or a `do` block, so
those are moved onto the local or replaced by `@param` and `@return`.

fmtk 2.1.4 onwards generates typedefs targeting emmylua that luals
misreads, and every fmtk changelog since 2.1.5 states luals support is
being dropped. luals 3.18.2 is already the latest release, so there is
nothing to bump.
The `--clusterio-modules` plugin has no emmylua equivalent, as emmylua
has no plugin interface, so it is reimplemented as `workspace.moduleMap`.
Those rules rewrite each file's own module path rather than the require
string, hence the reversed direction.
type.patch.lua is obsolete: `raise_event` now takes `LuaEventType` in
the generated typedefs, and `LuaObject` has become `LuaObject.base`.
exp_scenario/.luacheckrc was already dead, luacheck is never invoked.

The role system is moving onto clusterio's own roles and permissions, which
requires every in game action to exist as a real permission rather than a bare
string held only by the lua config.
Adds a permission for each of the 104 actions and 7 flags used by the legacy
role config. Names are derived from the legacy action by a deterministic
transform, exported so the lua side can apply the same mapping and keep existing
call sites working. Command descriptions are taken from the existing locale
entries so they match what players already see.
Actions held by the Guest role are marked grantByDefault, since the in game
default role and clusterio's default role are the same concept.
Role management actions have no scenario permission; they map onto
core.user.update_roles and core.role.list instead.
Also corrects the /unjail description, which was a copy of /jail.
