Drew T e7679b51ff docs(phase-32): T4b hand pass — row (c) func_80039308 PLATEAU at 4 (§501-O phantom-slot census for a leaf; ledger row); 🛑 CHECKPOINT refreshed for the pause: (a) PROVED · (b) BANKED commit:4001 · (c) PLATEAU 4 · (d) NEXT (sibling search first), then T4b close and T5
- (c): cnt's slot is spill_stack_slot[23] (evicted from $s7), so the phantom @0x8 must be an initial-loop no-traffic slot; every producer refuted on dump facts (leaf: no save area; LO spilled after GR and products alternate to GR_REGS — C3 measured; no unallocated single-block equiv pseudo; expand-time locals precede; 13 lh single-use, no lb). Rows 49/50 = two move_movables hoists in body order.
- row (d) read only (rtu DIFF 13 re-verified); brief + step 0 (§501-N banked-sibling search on its symbol set) in the checkpoint
- no src/ change in this commit; fleet R22 owed at the T4b close (last check-all 218/218 before the (b) bank)
