Backlog — automation near-misses for hand-finishing

Generated by tools/backlog.py render from .run/backlog.jsonl. These are functions the Phase-21 automation got close on but did NOT byte-match. The whole-binary byte-gate is the sole arbiter (G3/P9): byte-matches bank and are NOT listed here — only genuine near-misses/blockers are. Ranked by hand-session priority: reach (×N propagation leverage) → closeness (match_one mismatch count, lower = closer) → size. Each row's best_draft is the closest C the machine reached — resume from there.

Open near-misses: 115 · by status {'near': 72, 'failed': 43} · by class {'WAVE': 20, 'plumbing': 15, 'schedule': 28, 'struct': 15, 'regalloc-order': 27, 'remat': 2, 'other': 5, 'iv-combine': 2, 'loop-guard': 1}

Structure + regs otherwise byte-exact (frame eliminated via struct-array D_800AE7BC, &D_800B9A02 held in $a2 via the pB $6 pin, param_1+8 grouping fixes the rest).

With the frame forced (reserved local + anchor) gcc emits the prologue adjust at insn 0 instead of the delay slot (§5 frame-scheduling class); pins block the permuter, no C lever found to move it.

Single-buffer straight-line address reused across 2 calls -> CSE wins; no clean C (cast/type/union/ptr-var/$8-pin) flips it; two-distinct-locals remats but grows frame +8 (gcc-2.7.2 won't coalesce slots back to 0x18).

89	func_80147F78	134	schedule	48	failed		TWO residuals remain. (1) FRAME: target frame is 0x60 = exactly 64 bytes (16 words) of LIVE local vars on top of the 4 saved regs (s0,s1,s2,ra) + 0x10 arg area; my body has no locals so frame is 0x20. Reproducing 64B of live local needs an address-escaped local buffer, but the target has only the 3 visible jals (no 4th call to receive &buf), so I cannot make a 16-word local survive -O2 dead-store-elim without emitting an extra instruction. (2) RELOAD SCHEDULE: target reloads D_80127090/94/98 from memory (folded lui%hi;lw%lo) with the FIRST reload HOISTED up between store90 and store94 (free non-volatile scheduling); a "memory" clobber barrier (below) forces the folded reloads but pins them strictly AFTER all three stores. The natural source is almost certainly a 16-word local buffer that ALIASES the globals (non-volatile reloads, freely scheduled) — same construct that also explains the 0x60 frame. Closest faithful body kept below; folded reload bytes are correct, frame + hoist are the gap.	.run/backlog_drafts/func_80147F78.c
