None. A page earns its place by holding something no other source can, or
it is deleted. #
Seven pages under docs/: the model, who atgc acts as, agents publishing to
Tangled, the output contracts, the module layout, what earns a test, and the
environment. Flags are in --help, why a dependency is vendored is in
Cargo.toml, what changed is in git log, what is enforced is in
prek.toml — none of that is repeated, because a second copy is a second thing
to be wrong.
They are compiled into rustdoc through src/docs.rs, with
rustdocflags = -D warnings, so a reference from prose into code that no
longer resolves is a build failure. mdBook was rejected for being a second tool
outside the toolchain pin that could not check exactly that.
This register is under the same rule, and the entry below is the reason it
exists in this shape rather than as one flat file.
