Drew T f5498c3c66 feat(phase-30 S43): the 0xECC family — ONE crack banks 12 overlays / 11,364 ins [R22 PENDING] 
⚠️ R22 CLEAN-FLEET OWED (two agents still reading asm/, so `make clean` is unsafe). Each of the 12
was gated whole-binary AND independently re-checked against its own config/check.<bin>.sha (12/12),
stubs confirmed replaced — but incremental (§130). Treat as UNCONFIRMED until the clean run.

- THREE isolated cheap-Opus agents, briefed with §150/§151 + the mandatory all-drafts scan,
  CONVERGED INDEPENDENTLY: func_8017C6F4's 947-ins body exists in 12 OVERLAYS under 5 DIFFERENT
  NAMES at 6 DIFFERENT ADDRESSES, each differing by exactly TWO per-overlay symbols (screen-rect
  helper + 64x64 cell table). Gated 12/12, 0 failed. 11,364 ins from this morning's single crack.
- WHY IT HID ~30 PHASES (cookbook §152): name-keyed grouping scattered it across 5 names,
  address-keyed across 6 addresses (and the address collides with an unrelated 15-ins body in 3
  other overlays), and h_seq-keyed scattered it too — which is why the Phase-26 sweeps missed it.
  THE KEY IS BYTE SIZE: `grep -rl 'nonmatching .*, 0xECC' asm/*/nonmatchings/*/` returns exactly
  the 12, reads the asm (cannot go stale like family_hseq.json), no false positives. Refines the
  Phase-26 "h_seq is spent" finding: h_seq is worth exactly ONE size-keyed sweep behind each FRESH
  core crack — here it paid 11:1.
- TWO CAUTIONS THAT TRAVEL WITH IT: (1) a MASKED tool cannot validate a remap — match_one and
  rtu_match both mask jal/%hi/%lo, exactly the fields a remap edits, so a wrong symbol map still
  reports MATCH; gate remaps by the whole-binary SHA only. (2) a stale residual is NOT evidence two
  functions differ — I briefed "func_8017C59C scores 340, different body"; refuted in one command
  (that 340 came from a pre-§150-fix draft, which scores nonzero against its own target too).
- OPEN TOOL DEFECT (R32): family_remap's unit backscan halts at the first #define, so it carried
  16/16 gte macros and 0/10 typedefs, silently — the §146 gap from the other side.
- MY ERROR, RETRACTED IN THE LOG (S43-9): I reported the 263x5 cluster as "5 byte-identical, 1,315
  ins". FALSE — the drafts had been reverted, so I measured the INCLUDE_ASM STUB BASELINE, which is
  byte-identical by construction. R34's trap, self-inflicted by hand-building instead of using
  harvest_verify. Nothing was banked there; the cluster is UNRESOLVED. ("41 behemoth drafts" was
  likewise a file count — 79 files, 20 distinct functions.)

# splat config TEMPLATE — Brave Fencer Musashi location overlays (SCxx.CD/FILE_nnn/0.4.dec)
# =============================================================================
# Phase 13: the reusable flat-blob splat config for a LOCATION OVERLAY. ~134 overlays
# all stream into the SAME RAM slot (vram 0x80128158) and chain into the resident engine
# (0x800CEDF8) + the EXE. This is a TEMPLATE: the @TOKEN@ placeholders are substituted to
# produce config/splat.<alias>.yaml — by tools/new_overlay.sh (Phase 13 T4), or by hand
# (Phase 13 T1a for the first overlay). It is NOT a valid splat config until instantiated.
#
# Placeholders:
# ov_SC03_030 binary alias, ov_<SCxx>_<nnn> e.g. ov_SC01_077
# extracted/retail/SC03.CD.dir/FILE_030.dir/0.4.dec extracted 0.4.dec payload path e.g. extracted/retail/SC01.CD.dir/FILE_077.dir/0.4.dec
# 2fd8e113ce2f932fecc7df54702dc3108b47cb0a sha1 of the 0.4.dec (the build-identity target; also -> config/check.<alias>.sha)
# 0x80128158 load vram (the shared overlay slot) e.g. 0x80128158 (constant across overlays today;
# parameterized so a future non-0x80128158 overlay needs no template edit)
# 0x59CA8 file offset where code ends -> data tail begins (iterated vs the byte check, T1b)
# 0xB9AF0 file size in bytes (the EOF marker; = the 0.4.dec length)
#
# Modeled on config/splat.resident.yaml (the Phase-10 flat-blob recipe), with overlays'
# differences: (1) code at file offset 0x0 (overlays open with a function prologue, NOT a
# leading data word like the resident — so NO leading-rodata trick by default; see the
# commented `head` slot for the rare pre-code-data overlay); (2) symbol_addrs_path ALSO
# stacks config/symbols.resident.txt because overlays reference resident engine globals;
# (3) vram is the overlay slot. Everything else matches the resident options verbatim.
#
# Byte-match is robust to the exact text/data split (splat round-trips the bytes — the
# resident precedent); iterate 0x59CA8 against `make check BINARY=ov_SC03_030` (Phase-5/10
# precedent). LZSS is NOT in the verify path — we match the DECOMPRESSED 0.4.dec (repack is Gen3).
