:: :: /van/zuse
:: :: %reference/1
:: %zuse: arvo library.
::
:: %zuse is two nested cores: the first for models
:: (data structures), the second for engines (functions
:: or classes).
::
:: each of these stages is split into cores for each of
:: arvo's eight major vanes (kernel modules). these are:
::
:: - %ames: networking (rhymes with "games")
:: - %behn: scheduling ("bane")
:: - %clay: revision control ("play")
:: - %dill: console ("pill")
:: - %eyre: web ("fair")
:: - %ford: build ("lord")
:: - %gall: application ("ball")
:: - %kale: security ("jail")
::
:: with %zuse in your core, the engines of any vane are
:: available at `engine:vane`. the models (molds) are
:: available at `mold:^vane`.
::
:: every model or engine in %zuse is attached to some
:: vane, but any vane can use it (in its namespace),
:: as can any normal user-level code.
::
:: it's important to keep %zuse minimal. models and
:: engines not used outside a vane should stay inside
:: that vane.

:: Azimuth points form a groupoid, where the objects are all the
:: possible values of +point and the arrows are the possible values
:: of (list point-diff). Composition of arrows is concatenation,
:: and you can apply the diffs to a +point with +apply.
::
:: It's simplest to consider +point as the coproduct of three
:: groupoids, Rift, Keys, and Sponsor. Recall that the coproduct
:: of monoids is the free monoid (Kleene star) of the coproduct of
:: the underlying sets of the monoids. The construction for
:: groupoids is similar. Thus, the objects of the coproduct are
:: the product of the objects of the underlying groupoids. The
:: arrows are a list of a sum of the diff types of the underlying
:: groupoids. Given an arrow=(list diff), you can project to the
:: underlying arrows with +skim filtering on the head of each diff.
::
:: The identity element is ~. Clearly, composing this with any
:: +diff gives the original +diff. Since this is a category,
:: +compose must be associative (true, because concatenation is
:: associative). This is a groupoid, so we must further have that
:: every +point-diff has an inverse. These are given by the
:: +inverse operation.

:: +by-clock: interface core for a cache using the clock replacement algorithm
::
:: Presents an interface for a mapping, but somewhat specialized, and with
:: stateful accessors. The clock's :depth parameter is used as the maximum
:: freshness that an entry can have. The standard clock algorithm has a depth
:: of 1, meaning that a single sweep of the arm will delete the entry. For
:: more scan resistance, :depth can be set to a higher number.
::
:: Internally, :clock maintains a :lookup of type
:: `(map key-type [val=val-type fresh=@ud])`, where :depth.clock is the
:: maximum value of :fresh. Looking up a key increments its freshness, and a
:: sweep of the clock arm decrements its freshness.
::
:: The clock arm is stored as :queue, which is a `(qeu key-type)`. The head
:: of the queue represents the position of the clock arm. New entries are
:: inserted at the tail of the queue. When the clock arm sweeps, it
:: pops the head off the queue. If the :fresh of the head's entry in :lookup
:: is 0, remove the entry from the mapping and replace it with the new entry.
:: Otherwise, decrement the entry's freshness, put it back at the tail of
:: the queue, and pop the next head off the queue and try again.
::
:: Cache entries must be immutable: a key cannot be overwritten with a new
:: value. This property is enforced for entries currently stored in the
:: cache, but it is not enforced for previously deleted entries, since we
:: no longer remember what that key's value was supposed to be.
