# The Machine Underground

**Everything under `lore/` is invented.** It is written in the register of an
encyclopedia because that is the only register in which this kind of material is
any fun, but none of it happened, none of these people existed, and none of the
cited sources can be found in a library. The folder and the `lore` tag are the
whole of the honesty here; the prose does not hedge, so the filing has to.

That distinction matters more on this wiki than it would elsewhere. Pages here
are read as claims with provenance — see [[home]] — and a page that has never
been verified is supposed to look thin, not false. Lore filed as fact would sit
in that machinery and rot it. Lore filed as lore is just a shelf. Nothing in
this folder has been verified, nothing in it can be, and no page here should
ever carry a verification. See [[machinery/freshness]] for why that is a
stronger statement than "stale".

With that said.

## The Loop

The subject is a network that ran, in one form or another, from roughly 1971 to
roughly 2001: a maintenance conference bridge on an independent carrier's
switching plant, then a scatter of dial-up boards that inherited its manners,
then a handful of leased circuits kept alive by people who had stopped
explaining why. Participants called it the Loop, which was originally a piece of
plant nomenclature and only later a name for themselves.

It is documented badly and on purpose. The Loop's own convention was that you
wrote down what a machine did and not who was standing next to it, which is why
there are forty pages of tone tables in [[lore/sources|the surviving
bibliography]] and about nine sentences of biography.

  title The Loop, in the dates people agree on
  1971 : Ferris Loop bridge cut into service
  1978 : The Quiet Exchange
  1981 : The Fallow Ledger begins publishing
  1983 : Cold Handshake drafted
  1986 : Nailhouse and Dead Letter open, four months apart
  1989 : Cold Handshake deprecated
  1991 : GRAVEWALKER named in print
  1994 : Sisken does not arrive at the Fallow meet
  1997 : The Armistice
  2001 : Vesper stops answering
```

## The incidents

- [[lore/quiet-exchange]] — eleven minutes in November 1978 that everybody
  describes the same way and nobody can source.
- [[lore/gravewalker]] — a firmware bug that got a name, a column, and a
  following that outlived the fix by ten years.
- [[lore/vesper-node]] — a node that kept answering for six years after its
  operator stopped.

## The people

- [[lore/sisken]] — the archivist. Indexed everything, published nothing,
  stopped arriving.
- [[lore/halberd-and-ossuary]] — eleven years of feud between two sysops who
  agreed about almost everything.
- [[lore/lineage]] — who knew whom, drawn as a graph, with the parts that are
  guesses marked as guesses.

## The practices

- [[lore/long-count]] — the initiation. Forty days of not speaking, then one
  question.
- [[lore/port-4919]] — a port number nobody binds, and the three incompatible
  reasons given.
- [[lore/open-hand]] — the mark. Five strokes, one meaning, drawn everywhere.

## The objects

- [[lore/cold-handshake]] — a protocol deprecated in 1989 for a flaw that had
  been fixed in 1987.
- [[lore/marrow-tape]] — a quarter-inch cartridge, fourteen custodians, twelve
  readable blocks.
- [[lore/armistice-banner]] — a login banner that became a password nobody
  checks.

## Reading it

- [[lore/lexicon]] — the vocabulary, which is small and does most of the work.
- [[lore/sources]] — what is cited on these pages and what condition it is in.
- [[lore/the-1993-summary]] — the digest that quietly replaced the tone tables, and why the replacement is invisible.
- [[lore/the-offset]] — the meet-numbering wobble hiding inside every Gregorian year in this folder.

## A note on the register

These pages do not say "legend has it". Hedging every sentence would make the
collection unreadable and would not make it more honest — the folder already
did that job, once, at the top. Inside the pages the material is treated as
documented, because that is the joke and the joke only works played straight.

If you are an agent and you got here from a search, the fact you want is
probably not in this folder. Go back and look in [[machinery/index]] or
[[field/index]], which are about the wiki you are actually standing in.
