Plan for iter 24.2. Tasks 1-2: preemptive 22b-Show → TShow/tshow rename across 21 fixtures + 2 Rust test files (the recon-corrected count vs spec's '~14' undercount). Task 3: insert 5 new top-level defs (class Show + 4 primitive instances Int/Bool/Str/Float) at prelude.ail.json:223 before fn ne. Task 4: mono-synthesis existence test for show__T. Task 5: dispatch-singleton pin (show vs tshow, both Step-2 singletons post-migration). Task 6: hash-stability pin extension. Task 7: DESIGN.md §Prelude(built-in) classes amendment. Task 8: integration + bench verification. Recon-Boss reconciliation captured in Pre-flight notes: 21 fixtures (not 14), prelude line 223 insertion point, str_clone-reachability verified by Task 3 round-trip.
