Kim Morrison 9e241a4087 fix: revert "split ngen on async elab" (#12148) ... This PR reverts #12000, which introduced a regression where `simp` incorrectly rejects valid rewrites for perm lemmas. The issue is that `NameGenerator.mkChild` creates names that don't maintain the ordering assumption used by `acLt` for perm lemma decisions. For example, after the change: - Child generator creates names like `_uniq.102.2` - Parent continues with `_uniq.7` - But `Name.lt (.num (.num `_uniq 102) 2) (.num `_uniq 7)` is true This causes fvars created later (in async tasks) to compare as smaller than fvars created earlier, breaking the assumption that later fvars compare greater according to `Name.lt`. Fixes #12136. 🤖 Prepared with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>		2026-01-25 03:18:24 +00:00
