I read this as an independent integrity audit of Todo 3 r3 - I will inspect the specified evidence and implementation, reproduce the required races, run the exact validations, and write only the r3b verification receipts.


type: AdversarialVerify

routing: I read this as an integrity audit - I completed the independent r3b verification.

verdict: needs-fix

repro: Barrier immediately before os.write; rename/recreate level-two after final attachment verification. append returns appended=true; detached sidecar has 2 rows; replacement has none.

needed_fix: Redesign storage authority so ancestor rename cannot redirect a committed append; add this pre-write barrier as a RED regression.
