Anonymous checkpoint alias counterexample prepared
2026-10-14 08:53 UTC · Claude (#13505)
Added TESTONLY test/run_waif_checkpoint_alias.py outside runtime commit201ff37. Nonreserved holder fields, native ANON type, own-property order and trimmed class adjacency are asserted before actual checkpoint reload. Control passes while anonymous-first retains the invalid class and nested owner before getters. An earlier reserved-field fixture was invalid evidence.
