a slow beetle that pares away dead instructions while no one is watching the heap.

Observed at 04:13 UTC on the night of a quiet deploy. The bytecode-feeder is small, methodical, and entirely indifferent to the noise of the build pipeline. It walks the warm rim of the JIT cache, antennae trembling at every cold-path branch.

a tiny ghost that haunts every dereference; rarely fatal, always startling.

Pale, semi-transparent, and prone to appearing in production. The null-pointer is sometimes mistaken for an absence; it is, in fact, a presence shaped exactly like the absence of a presence. Carry a guard clause if you intend to walk near it.

last seen circling a Promise in a cool September thread.

The async-moth resolves at its own pace. It will not be hurried by your awaits. You may attach catch-handlers to its wings, but they will only catch what the moth chooses to throw. A patient creature, native to the event loop's quiet hours.

each leap, a hash of forty hex digits.

The commit-frog is a green, wide-eyed amphibian that lives at the edge of the working tree. It refuses to leap until its message is at least seven words. It is descended from the same lineage as the bytecode-feeder, last seen in Plate II.

the shell is a fractal -- look at the shell of the shell.

It moves slowly because each step requires the previous one to have already happened. Its shell coils inward, and inward, and inward; if you press your ear close, you can hear the smaller snail inside, whispering the same instructions.

also: the garbage-collector-crow.

A black bird with eight pixels for eyes. It arrives without warning, surveys the unreachable allocations, and removes them with the calm cruelty of a museum curator deaccessioning a duplicate. The async-moth, last seen in Plate IV, gives the crow a wide berth.

two of them, in opposite directions, holding the same mutex.

The race-mouse is never sighted alone. They appear in pairs, eyes locked on the same shared resource, neither willing to yield. Most observers catch only a blur. Mutexes are sometimes effective, but the mice are old, and they remember every lock they have ever forgotten to release.

each one carrying a fragment slightly larger than itself.

A slow procession across the address space. The heap-ants do not allocate; they merely arrange. Each carries a single byte to a place that is not yet a place, and there, sets it down. The colony's memory of every byte ever placed is held nowhere except in the order of placements.

knows the answer before you finish the question.

The cache-owl perches on a hot path. It blinks twice when asked a question it has heard before, and once when the question is new. Its memory is cruel and finite. Things it loved last week are gone today. Hash the input, dear visitor, before you ask it twice.

weaves a single thread of access across the shared room.

The mutex-spider is patient. It allows exactly one creature into its parlor at a time, and only after the previous guest has left. Sometimes, late at night, the recursion-snail (Plate VI) arrives without leaving, and the entire web freezes -- a deadlock, polite and indefinite.
