Operator Filter Registry

  • Name: Operator Filter Registry

  • Status: alias of operator-filter-registry

  • Why this note is not separate: Operator Filter Registry is a mechanism/reference note, not a standalone vendor or app page. The sharper taxonomy is one canonical reference page under references/standards plus this alias so older links and filenames still resolve cleanly.

  • Canonical note: operator-filter-registry
