The engine's errors

Every error the engine can report, from its one declared list (tools/lusine/errors.py). Each is a code, which the control channel's refused field carries (the set is closed: a code outside it is a protocol failure), a line in every language the status panel shows with its slots filled, and the line's lifetime on the panel: dismissed stays until the player dismisses it or the next event replaces it, timeline clears when the timeline passes. A failure that is not a row here cannot be reported. Generated at build from the list and the catalogue, so it cannot disagree with either.

Code	When	Slots	Lifetime	Answered by
bad-request	the request's shape: a missing or ill-typed argument, a field outside its declared range	operation: the operation asked for; argument: the argument at fault	dismissed	describe, compile, drop, call, read, load, append, remove, save, restore, quit
name	a name the definition does not declare, refused where it is written	name: the name as written	dismissed	drop, call, read, load, append, remove, save, restore
stamp	an action stamped with a step already passed, or a readout past the engine's history	step: the step it was meant for; now: the step the world is at	dismissed
action	an action the game's own rule refuses: out of turn, out of balls	action: the action refused	dismissed
size	a load whose extents the running scene cannot take	got: the save's extents; expected: the extents this world takes	dismissed	restore
io	a file that cannot be read or written	path: the file	dismissed	save, restore
not-in-this-build	an operation or a readout the release does not carry (ship=False), in a release build: an instrument, refused by code rather than absent	operation: the operation or readout asked for	dismissed
script-timeout	a script's done for a step that came after the step's budget: the engine went on without its operations	step: the step the script did not finish in time	dismissed
declare	a declare whose text is not one line of Trait's runtime subset (readout, event, band, say, sound, setting, panel, on), or is not well formed	expected: what the subset takes at that column	dismissed
unresolved	a name in declared text that resolves to no declaration the session can reach	name: the name as written	dismissed
ambiguous	a name declared twice under one owner	name: the name declared again	dismissed
owner	a declaration under another owner's name, or a reach into another session's	name: the name as written; owner: whose it is	dismissed
unit	an expression whose dimensions disagree, or a readout whose expression is not in its declared unit	got: the unit the expression has; expected: the unit declared	dismissed
slot	a line's slot with no band and no event field to fill it, or a key no declaration names	slot: the slot	dismissed
budget	a declaration past the session's budget of live reduce instances	limit: how many the session may hold	dismissed
device	a Vulkan object or call the engine needs failed	what: what the engine was making or doing; result: the Vulkan result	dismissed
unsupported	an operation this device or this build cannot do: GPU timestamps a run needs, a second compute queue a measurement needs, a developer build a ship=false pass needs	operation: the operation asked for; feature: what it needs and lacks here	dismissed	compile, drop, call, read, load, append, remove, save, restore
ir	a game's compiled program refused at load: one this engine cannot run, or a tuning table beside it of another shape	file: the file refused; what: what in it this engine does not run	dismissed
save	a save refused for what it holds, its size and its file aside: another game's, a quantity missing, or one of another kind, element, unit or quantum	path: the save; what: what in it does not fit this world	dismissed	restore
capacity	a list's appends in one step past its capacity: the step keeps the first in item order and drops the rest	list: the list; dropped: how many appends the step dropped	dismissed
command-line	a launch argument the engine does not take	argument: the argument as given	dismissed
compile	a session's Trait source the compiler refuses: its refusals in trait's words, session:LINE:COLUMN: code: why, the line and column of the first in the text sent	refusal: trait's first refusal, as it gave it	dismissed	compile, drop
token	a listener's connection whose first request does not carry the token its token setting asks: the connection is closed		dismissed
