docs(refactoring): refresh R2 status after #35#36
Merged
Conversation
R2 still claimed the transformer migration was entirely outstanding, which stopped being true at #33 and #35. Record the real position: 3 of 11 migrated, and those three are exactly the boundary-crossing ones. Replace the vague "migrate the ~10 transformers" with a priority-ordered table, so the sequencing rationale survives the session that produced it.

R2's status line still read "helpers landed (#31); transformer migration outstanding", which stopped being true at #33 and #35.Refreshes it to the actual position — 3 of 11 transformers migrated, namely the three that cross the scope boundary — and replaces the vague "migrate the ~10 transformers" with a priority-ordered table carrying the remaining
SqlExpression::pattern count per file.Ordering rationale, so the next session doesn't have to rederive it:
having_alias_transformerfirst: it's P9, the only one with a live wrong answer (HAVING COUNT(*) BETWEEN 1 AND 2→ 4 rows vs DuckDB's 1, silently). Corpus case before the migration.map_childrenis load-bearing for them.WindowSpec::order_bywarning: no blanket "pure refactor" claims, since two of the bugs refactor(query_plan): migrate the three boundary-crossing transformers onto walk.rs (R2, group 1) #33 fixed were exactly that.Docs only.
