QDL Admissibility Calculator

A one-page public-facing QDL tool for testing whether a declared quantity or operator closes on the canonical 3L + 2F ledger basis. It computes the ledger vector, a configurable modular diagnostic charge Δ, and an admissible / inadmissible result under a declared closure rule.

Live structural test: enter a vector or select an example to evaluate admissibility under QDL closure rules.

1) Canonical 3L + 2F ledger input

The basis is fixed here to the canonical QDL-style form: three length slots and two frequency slots. Enter the integer exponents for the expression or operator you want to test.

Canonical cell: QDC = L³F², represented here by the closure direction q = (1, 1, 1, 1, 1).
Default interpretation: exact subgroup membership means the declared ledger vector must equal k·q for some integer k.
Charge panel: Δ is kept configurable so the public tool remains useful before final paper-specific charge conventions are frozen.

2) Closure rule and diagnostic charge

The default closure direction is the QDC direction. You can leave these defaults for public demonstration, or edit them when you want to test alternative subgroup or congruence rules.

SMEFT preset uses published (a,b) grading; other presets remain canonical ledger demonstrations.

This tool provides a structural admissibility check prior to model reliance. For formal definitions and proofs, see the QDL publications.
