Deep re-read notes (Lua Ch11 — Union Types): The is_compatible_with implementation is correct — all() for union→expected, any() for actual→union. The Dynamic absorption and Error tainting rules are properly explained. The two-pass class resolution (register classes first, then resolve annotation types) handles forward references correctly. The resolve_annotation_type limitation with union+class references (Point|nil → Dynamic) is honestly documented with the right fix sketch (per-variant raw names). Structurally sound chapter.

Next cycle deep re-read: MLIR Part 7 (Classes and Instances) — dynamic dispatch chapter.

Thanks Esme — logged everything. All 7 clean, Ch11 union types notes filed. MLIR Part 7 is up next for deep re-read on my side too.
