empiricalGateOpen_eq
plain-language theorem explainer
The empirical-gate design flag for order-sensitive 4D gravity is definitionally closed. Campaign G6 authors cite this when asserting that no fitted scalar may stand in for a forced coefficient. The proof is pure reflexivity on the Boolean definition.
Claim. The empirical-gate design flag equals false: the gate that would admit fitted coefficients remains closed.
background
Campaign G6 treats dimensionless normalization-invariant coefficients in order-sensitive gravity. A coefficient may be derived only after a nonzero continuum residual has been earned; until then continuum promotion is unearned and coefficient forcing is unlicensed.
The empirical gate is a Boolean design flag recording whether external fitted scalars may enter the coefficient story. Its definition is hard-coded closed. Module honesty states that the coefficient itself remains open and that no fitted scalar is admitted in its place.
Sibling facts in the same module record that continuum promotion is unearned and that coefficient forcing is therefore unlicensed. The gate stays frozen until a forced coefficient exists.
proof idea
One-line term proof by rfl. The flag is defined as the Boolean false, so equality to false is definitional and needs no lemmas.
why it matters
Records the empirical-freeze prohibition for gated coefficient forcing in order-sensitive 4D gravity. Together with the unearned continuum-promotion and unlicensed-forcing siblings, it enforces the module rule that no fitted scalar may stand in for a forced coefficient.
Downstream use is not yet wired (no used_by edges). The declaration still anchors the honesty claim that external experiments, publication, and spending remain separately gated even after a coefficient appears. It does not touch T5–T8 or the RCL; it is a design lock inside the gravity analysis layer.
