Match func_ov002_020bb520 byte-identical (mwccarm 1.2/sp2p3)

[lunavyqo]

Summary

• Matched func_ov002_020bb520 (ov002 @ 0x020bb520, 244 bytes) byte-identical on mwccarm 1.2/sp2p3, linkcheck VERIFIED.
  • Lever: goto fail / goto success for shared unconditional fail epilogue after FindWithID, plus named (int)(type == 0xbf) bool materialization (moveq/movne/cmp/bne).
• Near-miss tip for func_ov062_02119af0 (ov062 @ 0x02119af0): 17 → 14 word divergences banked in nearmiss/db.jsonl.
  • CF fix: when dot <= 0 the path still advances; shared ret0 via goto; GetNode takes the current count (no mov r2,#0).
  • Residual: register-coloring floor on prologue temps / cnt pointer (r6/r4/r1).

Test plan

• python tools/match.py --c src/func_ov002_020bb520.c --func func_ov002_020bb520 --addr 0x20bb520 --size 0xf4 --version 1.2/sp2p3 --bin extracted/dsd/arm9_overlays/ov002.bin --base 0x020ad660 --module ov002 → MATCH
• python tools/linkcheck.py --name func_ov002_020bb520 --addr 0x020bb520 --size 0xf4 --module ov002 → VERIFIED
• CI validate green on the matched file only

_{Each changed src/*.c|*.cpp is compiled and its relocated bytes compared to the binary data on a private build box. Passing requires every changed file to reproduce the ROM byte-for-byte with correct relocation targets — this catches WRONG-DEST relocations and non-reproducing near-misses that ledger-scoped linkcheck skips.}

Match landed on main as f117c01 with your authorship, combined with #659/#660. Both re-verified byte-identical. #659 also re-carried the func_ov007_020c25fc match already on main (no-op), six ghost near-miss entries for functions matched via #655-658, and a func_ov002_020e7454 21→35 regression — all skipped so nothing on main regressed.
