Nothing in this repository was verified by anything but reading, which is how
a superseded decision stayed live in the constitution and in the to-be README
at the same time. Both were found by a person looking, and nothing stopped a
third.
Five checks: links resolve; `decisions:`/`extends:` name records that exist and
are accepted; a governing document citing a superseded record must name its
replacement in the same paragraph; supersession is symmetric; filename number
matches heading number.
Each was made to fail before it was made to pass. The live-citation check was
verified against a reconstruction of the actual incident -- the to-be README
citing ADR 0017 as live guidance -- and reports it with file and line.
It found one thing nobody had noticed: ADR 0018 never declared that it
superseded 0011, though 0011 has named 0018 as its superseder since August.
Fixed.
Deliberately not checked, and said so in the README: 02-DECISIONS and
01-RESEARCH may cite superseded records freely, because a decision record
discusses history and research records what was observed. 00-as-is may rest on
one, per 0056. Flagging those would put noise on correct documents, and a check
that cries wolf gets suppressed -- which costs more than not having it.
Two bugs found by running it: the frontmatter reader iterated an inline list as
characters, and the as-is exemption was missing entirely.
