2026-06-15 (QGEO: the pillowcase reduction — two residuals become one canonical metric)
Research changelog · TFPT — Introduction and reading guide
Pillowcase reduction of QGEO.SYM.01 ( v214_seam_pillowcase, tfpt_research_contracts, / ; ledger QGEO.PILLOW.01). The two separately-tracked open QGEO residuals — QGEO.ISO.01 ( v180: the carrier clock is an order- [formula in source] isometry of the seam metric) and QGEO.SUBPRIN.01 ( v201: the DtN sub-principal symbol is mark-local, the seam flat away from the [formula in source] marks) — are shown to be one statement
Opening source excerpt. Formulas and the full argument remain in the original document.
