Drew T c6b380fcd0 phase-36: T7 burst — 503 more bodies banked, and the per-file scratch-object collision fixed at its cause

The scorer named its scratch object after the FILE (compile_obj tag="score"), so the nine burst agents sharing one
translation unit wrote and read one object. Two reported it independently without seeing the code: spurious
COMPILE-ERRORs naming an unrelated header, and one agent scoring four candidates against another agent's function. The
tag is now per function. Every landed body was re-verified after the fix and all still score 0; the banks were never at
risk, the agents' intermediate readings were.

- banked: func_801627E8 (132), func_8017A3D8 (118), func_80141874 (119 of 125), func_801345F8 (134). 28,887 -> 27,984.
lever_census --check: 27,984 pin/asm sites, 27,984 marked !FAKE, 0 UNMARKED — OK
- THE FINDING: the biggest lever class in this phase is a WRONG DECLARATION, not codegen. Four agents independently
reached score 0 by restoring a call's real arity, each in a different spelling — a function-pointer cast, a widened
block-scope prototype, a call given its argument, and a definition given its two parameters. The mechanisms differ
(combine.c:1458's added_sets_2 gate; set_preference global.c:1589 ahead of first-fit at :1001-1015, the argument copy
becoming a self-move deleted at toplev.c:3142 so it costs zero instructions; assign_parms' parameter home copies) but
the class is one: a truncated (void) declaration removes an instruction the pin was then hired to fake. No generator
can reach it — every generator rewrites statements that exist, and this changes a call's arity.
- func_80157D20 does not bank body-only (gcc rejects a block-scope redeclaration), so its Path A joins func_80136824 and
func_80168828 as the third measured case for the types phase.
- two more new classes, byte-proven: a store sinking past a load because true_dependence's exception (sched.c:837-839)
discards the edge, fixed by declaring the global an array and storing through [0] to set MEM_IN_STRUCT_P; and a
post-decrement queued by expand_increment until the next sequence point, fixed by splitting the statement plus a u16
destination cse refuses to join (cse.c:1017-1019).
- correction to record: an uninitialised register __asm__("$0") is an opaque operand, not a constant holder — R16 must
refuse it.
- snapshot row 20.
