+ * func_80066DA0 — 140 bytes at 0x80066DA0..0x80066E2C
+ *
+ * For index 23, writes one to *a2 when the absolute halfword at 0x80122514 is
+ * zero, otherwise writes zero; it also clears *a3 when non-null. For other
+ * indices, loads the table pointer at object+0x20, forms a row at index*4, and
+ * copies the halfword at +0x46 to *a2 and +0x44 to *a3 when those outputs exist.
+ *
+ * The special-index arm uses an explicit nonzero-to-zero-store label so the
+ * target's bnez/jump/delay-slot layout is preserved. The absolute halfword read
+ * is intentionally a literal address rather than the gp-marked symbol: the target
+ * materializes 0x80122514 with lui/lh.
+ *
+ * LIMITS: the object table and output meanings are not inferred. The selector
+ * value 23, absolute halfword address, object table offset 0x20, row offsets
+ * 0x44/0x46, null checks, and return are byte evidence.
