< p class = "inwebparagraph" > < a id = "SP1" > < / a > < b > § 1. Stages II to IV. < / b > The process of using existing facts to infer new ones is vulnerable
to timing bugs, so we organise the "making" process into five numbered
stages, given the Roman numerals I to V. Much of the work is done by plugins,
which can take a hand at any or all of the stages, using their contextual
knowledge to fill in missing properties.
< / p >
< p class = "inwebparagraph" > < / p >
< ul class = "items" > < li > (I) Deducing the kind of any object whose kind is not known. Because this
can result in a change of kind, which can result in further creations by
assembly sentences like "A handle is part of every door", Stage I takes
place at the end of traverse 2 of the source text and, uniquely, gets the
opportunity to add fresh sentences to the source — thus extending the
traverse. By the end of Stage I, all kinds are fixed.
< / li > < / ul >
< ul class = "items" > < li > (II) Stages II and III are for adding further properties or relationships,
which aren't explicit in the source text but which plugins can add on the
basis of contextual understanding. (Two stages are provided here to avoid
timing issues where one plugin has to act earlier than another.)
< / li > < / ul >
< ul class = "items" > < li > (III) See (II). If a plugin is going to change the compilation order of
the objects (as the spatial-model plugin does), it must do so during
Stage III.
< / li > < / ul >
< ul class = "items" > < li > (IV) A stage for consistency checks or to store away useful data, but where
nothing in the model may be changed — no properties or relationships
may be added. (Except that the instance-counting plugin is allowed to
add the linked-lists-of-instances properties, used to optimise loops
at run-time; they aren't visible at the I7 level so aren't properly
part of the model world.)
< / li > < / ul >
< ul class = "items" > < li > (V) A final chance to add properties which will assist the run-time
implementation of, for instance, the command grammar, but again aren't
really part of the model world. (This can't be done earlier since the
command grammar isn't parsed until after < code class = "display" > < span class = "extract" > World::complete< / span > < / code > ; and we
aren't allowed to add I7-accessible properties.)

< / p >
< p class = "inwebparagraph" > The answer is that both depend not only on the subject of the inferences
made, but also on what that subject inherits from. Suppose we are told:
< / p >
< blockquote >
< p > The cup is in the Yellow Cupboard. The Cupboard is lighted.< / p >
< / blockquote >
< p class = "inwebparagraph" > When we make the "lighted" inference, we know for certain what subject
it's about — the Yellow Cupboard — but not where this lives in the
inference-subject hierarchy, because that depends on the kind of the
Cupboard. Is it a room, or a container? We don't yet know (and won't until
Stage I of model-completion), so we aren't in a position to judge whether
or not it's permitted to have the property "lighted". This is why the
check is postponed until after Stage I, and it seems natural to perform
it here in Stage IV, so that we also catch any accidents due to bugs
in plugins which add inconsistent properties.
