Sylpheed RE agent 50625b5a9e re: REGN is a tetrahedral navigation mesh — the cell→geometry link, decoded
Found the reader. It is the deserialiser, not a consumer, and it answers the
question twice: the fixup base is chunk+0x10 (82465198 addi r3,r31,16), so
every offset previously recorded was read 16 bytes early — which is why twenty
correlation tests sat at chance — and the POF0 table names every pointer word
in the file.

Six sections, not four. cell {count,item*} → item {n@+0x10, refs*@+0x14} →
array of pointers into section 1 → a 96-byte tetrahedron. Section 2 is a face:
plane, its three vertices, the two tetrahedra either side (0xFFFF = hull) and
their face slots.

All 11 objects: face passes through exactly 3 of its tet's 4 vertices in
253 722/253 722 (random control 0.07–2.2 %); portal cost == face-centroid
distance in 380 460/380 460; sphere reaches its cell 98.7–100 % vs 18–28 %
with transposed axes.

Refuted and kept: 'REGN'/'MCOL' are never built as constants in the executable
(0x474E occurs zero times in 1.87 M instructions), so no magic-dispatch site
exists; and "zero portal-pair float marks a hull edge" shows no lift at all.
Still open: the runtime consumer of the grid, the second portal float, and the
four flag bytes at tetrahedron +0x54.
