Native-RE (Ghidra) cracked call-script <id> (opcode 0x03): its handler
FUN_0041bc90 -> loader FUN_0040e980 -> resolver FUN_0044f390 indexes an
80-byte record table at base + id*0x50 == the SYS4INI record layout. So
`call-script <id>` is a direct RAW index into the SYS4INI global file
table (the asset index we already parse) -- there is no separate on-disk
id->code registry. This resolves name-resolution.md #1, statically, no
Frida.
Confirmed: all 297 distinct corpus call-script ids resolve to a .BIN
script with a semantically-exact name (0x1ab->ADDITEM, 0x2ae7->MES,
0x143->BUNKI, 0x329d->CALCREVISE), 0 out-of-range, 0 alternate-pack.
Companion op 0x8f `call` is an intra-script JSR (FUN_0041fba0), not
cross-script.
- parse_sys4ini.py: preserve `raw_index` per entry (= the engine file id;
index the RAW records incl. '@' placeholders) + emit
build/callscript-names.json (id->name).
- sys4load.py: annotate `call-script 0x1ab =ADDITEM.BIN`.
- opcodes.toml 0x03/0x8f refined (source=investigation, confidence high,
handler VAs) + rebuilt opcode-reference.md.
- docs: engine-re.md (op 0x03 section + backlog re-aimed),
name-resolution.md #1 (SOLVED), script-inventory.md (call graph +
living-reference decision), tools-reference.md.

Anchored the opcode dispatch table: handler(op)=ctx[0x26c93+op] (default FUN_004162b0,
registered by FUN_00413860). Corrects the prior note: raw Kelebek VA 0x428010 is op
0x1ac (a save op, 0x427fb0); op 0x1a2's REAL handler is FUN_0042d360 = a graphics
command-buffer op (cmd-type 3, '%c%8.8x' key). So u00428010 is NOT decision->scene and
NOT save; the FIELD 0x5f0ed/0x62ccf snippet is gfx/UI. decision->scene premise discredited;
real mechanism = call-script/script-load (still unidentified). Lesson: resolve handlers
via the table, never the raw Kelebek VA.

Ghidra+MCP workflow validated. Found the opcode->handler dispatch table
(*(ctx+0x9b8f4+op*4), registered by FUN_00413860) — the general fix for Kelebek VA
drift. Corrected: u00428010 (op 0x1a2) is a save/resource op, NOT decision->scene;
the SCJUMP consumer persists the visited-decision flag. New doc docs/engine-re.md.
