+ * func_801029A0 — 96 bytes at 0x801029A0..0x80102A00
+ *
+ * Clears four absolute-global words, calls func_801092C0 with zero and the value
+ * loaded from D_801461D8, then clears the following global, the halfword at
+ * 0x801461BC, and the final global word.
+ *
+ * The repeated `lui at`/absolute displacement stores are intentional: direct
+ * address-named globals force a fresh absolute materialization for each statement,
+ * matching the target's initializer rather than a strength-reduced base pointer.
+ * The call deliberately has two arguments; the first loaded global is the second
+ * argument and remains live in a1 across the zero stores.
+ *
+ * LIMITS: the global meanings and the callee's behavior are not inferred. The
+ * addresses, store widths/order, two-argument call dataflow, frame, and return are
+ * byte evidence from the USA executable.
