Folds byte-identical template instantiations: mrmeshpy.so -11% unpacked, -2.3 MB compressed per wheel; full distro test matrix passed on an ICF build.
Points thirdparty/mrbind at MeshInspector/mrbind#42 (branch table-driven-py-registration); to be re-pointed at the merged master commit once that PR lands.

Superseded by #6574, which picks up mrbind#44 instead of the withdrawn mrbind#42. mrbind#42 was rejected for replicating pybind11 internals; mrbind#44 achieves nearly the same size reduction while reimplementing nothing from pybind11, so this branch is obsolete. |

thirdparty/mrbindto pick up MeshInspector/mrbind#42 (table-driven Python bindings registration). Originally stacked on #6535'sbindings-icf; that PR has merged, so this now targets master and the combined numbers below reflect both changes together.Note: the gitlink currently points at the mrbind PR branch head (8f8b1b6f); it will be re-pointed at the merged mrbind master commit once mrbind#42 lands, before this PR merges.
Measured effect (same-commit A/B vs pre-ICF master)
Manylinux dry runs 31128567300 (this mrbind commit) vs 31126757168 (master baseline):
mrmeshpy.socompressed in wheelmrmeshpy.so.textmrmeshpy.pyiis byte-identical to master's on x86_64; behavior is unchanged (the Python test suite passed on all 14 manylinux legs, and a full-platform dry run 31129376919 incl. Windows and macOS was green).Combined with ICF (#6535)
Stacked measurement (this PR on top of #6535's ICF), dry run 31156684018: x86_64
mrmeshpy.so12.39 MB zip / 51.5 MB raw — vs 19.32 MB master and 14.80 MB table-driven-alone. The two changes compose almost perfectly (−35.8% zip combined); ICF retains its full ~2.4 MB on top of the table rework.🤖 Generated with Claude Code
