# 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:** 100  ·  by status {'near': 62, 'failed': 38}  ·  by class {'WAVE': 24, 'struct': 13, 'schedule': 22, 'plumbing': 12, 'regalloc-order': 22, 'remat': 2, 'other': 2, 'iv-combine': 3}

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. Frameless form left here = body byte-exact, 2 frame insns short. | `.run/backlog_drafts/func_80175820.c` |

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).

Target uses ONE IV at p+0x20 (byte at 0, halfword RMW at -2); our cc1 either (a) merges into ONE IV but bases it at the LOWEST offset = the halfword (+0x1e), so every load/store offset is shifted (0/2 vs -2/0) and byte-differs; or (b, this draft) keeps the byte biv at the correct +0x20 base but SPAWNS a 2nd IV (+0x1e) for the RMW halfword -> +1 addiu + schedule shift (28 mismatched, mostly the 2nd-IV addiu and a 1-row delay-slot schedule shift). Probe-confirmed: even with both fields as forward non-negative struct members, the halfword RMW never folds into the byte biv (a non-RMW byte/halfword pair DOES merge). Genuine gcc-2.7.2 giv-combination divergence, not source-typeable. Matches the Phase-20 §20 verdict (independently re-derived). STUB. | `.run/backlog_drafts/func_80177AD4.c` |

| 55 | func_801778A8 | 134 | iv-combine | 38 | near | 38 | gcc spawns 2 IVs (byte giv @+0xc, halfword RMW giv @+0xa); target combines both into ONE IV at +0xc reaching the halfword at -2($a3). A struct collapses to 1 IV but anchors at the struct base (+0xa) not +0xc; raw byte+halfword RMW never combines. Same combine_givs-refuses-halfword-RMW wall as sibling func_80177AD4 (§20, stubbed). Floor 33-off; not source-steerable (combine runs pre-regalloc, pins/order don't move it). | `.run/backlog_drafts/func_801778A8.c` |

To match, the loop-pass insn_count would need >=60 so threshold*1*1 < insn_count after the first hoist; clean C producing the identical final logic yields 46. Pins free regs (more hoisting), barriers/volatile/for-vs-do-while don't raise insn_count. ~45 masked-mismatches all cascade from the 5 hoisted-vs-inline constants + their register reassignment. | `.run/backlog_drafts/func_80177EA4.c` |

| 78 | 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` |
