special_case_of → color_code_2d pending

This entry fixes the honeycomb bulk tiling and one explicit triangular three-color boundary convention inside the wider family of 2D color codes on trivalent, face-three-colorable cellulations.

product_of → surface

Local Clifford unfolding maps a closed 2D color code to two surface-code copies; for the triangular boundary, the copies remain attached along a fold. This is an equivalence dictionary, not the constructor recipe used for the exact face-incidence matrix here.

same_bulk_phase_as → color_488

The 6.6.6 and 4.8.8 tilings realize the same abstract 2D color-code order, while face weights, finite-boundary staircases, qubit counts, and extraction circuits differ and must not be transferred numerically.
