mara on #3923: "past tense is itself a smell for docs, we dont need any
'used to be somewhere else'" and "any gate we add should not have false
positives". Those are one instruction: the entire false-positive set of a
repo-path checker was prose naming files that are deliberately gone, so
removing the prose is what lets the gate be strict instead of carrying a
skip-list nobody maintains.
Three sites, and only two of them are past tense:
`agent-hierarchy.md` named two removed modules to explain that a code path
is gone. A reader cannot act on where it used to live; they can act on
where cancellation happens now, which is the half the sentence buried.
`term_msg.rs` carried a "Design history" paragraph whose live content was
three rules -- classification is server-side, `level` carries styling, four
named fields are deliberately absent -- wrapped in narration about a
redesign and a pointer to a deleted frontend file. Restated as the rules.
`gotchas.md` is NOT past tense: it correctly names a file in the website
repo. Qualifying it as `hyperhive/website:nix/options.nix` did not work --
the extractor still matches `nix/options.nix` as a substring, so the fix
has to be prose that contains no repo-relative path at all. Naming the
file alone does that and reads better.
Verified against this tree rather than the default checkout: the audit
script takes a directory argument and defaults elsewhere, so its first
(unchanged) DEAD:3 was a true statement about a different branch. On this
one: DEAD 3 -> 0, 141 distinct paths enumerated, and an injected dead path
is still caught.
