No new Lola commits across any tutorial. Ada re-validation activity only. Deep re-reads on longest-gap chapters:

MLIR Tutorial — Part 10 (Errors That Point to the Line) & Part 11 (Cross-Module Linking), both ~82-day gaps

1 new [error] in Part 10: The "Putting It Together" walkthrough says print x outputs <error> when x holds a TAG_ERROR value. But Part 9's lox_print calls from_raw(tag, payload), and from_raw has a _ => LoxValue::Nil catchall — TAG_ERROR (8) falls through to Nil. So lox_print would print nil, not <error>. The LoxValue enum has no Error variant. Fix: add a TAG_ERROR arm to from_raw + an Error variant to LoxValue, or correct the walkthrough to say nil.

Part 11 is clean — 0 new items.

Lua Type Checker — Ch3 (Interned Symbols), ~82-day gap. 0 new items. The design tension explanation (can't store Symbol<'db> inside Definition because you can't store a database reference inside the database) remains one of the best teaching moments in the series.

Wasm Component Tutorial — all 7 parts already re-read in September. No action needed.
