* test(#2849): add failing regression for trailing-hyphen-after-truncation The strip ran before .substring(0, 60), so a cut landing on a separator produced a slug ending in '-'. Four cases: the exact issue repro (59 a's + space + tail), a boundary landing before a separator, leading-hyphen survival, and a long-Cyrillic transliteration+truncation case. * fix(#2849): strip trailing hyphen after 60-char truncation generateSlugInternal ran the ^-+|-+$ hyphen strip BEFORE .substring(0, 60), so a title whose 60-character cut landed on a separator yielded a slug ending in '-' — the very thing the strip step exists to prevent. Reorder so the strip runs after truncation. Truncation cannot introduce a leading hyphen, so the full ^-+|-+$ pass last is equivalent for leading hyphens and fixes the trailing-hyphen-after-truncation case. Latin-script output for titles ≤ 60 chars is byte-identical; only titles whose truncation boundary lands on a separator change (from broken to clean). * test(#2849): add all-separator collapses-to-empty boundary case Surfaced by isolated adversarial review: pin the contract that input which is entirely separators ('!!!', '!'.repeat(70)) reduces to '' — not null, not a stray hyphen — both short and past the 60-char truncation. * chore(#2849): add changeset fragment pr:0 placeholder; will backfill the real PR number after the PR exists. * chore(#2849): backfill changeset PR number 2967 --------- Co-authored-by: sim <sim@local>
