"""Regression: _extract_headings must emit a unique slug per heading.
|
|
|
|
_make_slug disambiguates repeats by appending "-N", but it only tracked the
|
|
*base* slug, so a generated "intro-1" could collide with a naturally-occurring
|
|
"intro-1" (e.g. headings "Intro", "Intro", "Intro 1" all produced
|
|
["intro", "intro-1", "intro-1"]). Duplicate slugs become duplicate heading ids,
|
|
which makes the second table-of-contents link dead. Slugs are now guaranteed
|
|
unique. Plain repeats keep their existing "-1", "-2" sequence.
