rs_correction
plain-language theorem explainer
rs_correction supplies the phi-ladder gap term that enters the anomalous magnetic moment for any charged lepton. Researchers extending QED calculations with Recognition Science residues cite it to isolate the universal correction shared by electron, muon, and tau at fixed Z=1332. The definition is a direct one-line alias to gap_lepton, inheriting the residue extraction from RSBridge.
Claim. For lepton $l$, the RS correction is $rs_correction(l) := gap(Z_l)$, where $Z_l$ is the effective phi-ladder rung for that lepton and $gap$ extracts the residue at that rung.
background
The module extends the phi-ladder residue mechanism to QED anomalous moments $a_l = (g-2)/2$ for charged leptons. All charged leptons share gauge charge $Q=-1$, hence the same $Z=1332$, producing a universal RS correction term. The full moment is written as Schwinger plus higher loops plus this RS term, with the RS part identical across $e$, $mu$, and $tau$ (MODULE_DOC). Lepton is the inductive type with constructors $e$, $mu$, $tau$. gap_lepton($l$) is defined as RSBridge.gap($Z_lepton$ $l$), pulling the residue from the phi-ladder at the lepton-specific rung (UPSTREAM gap_lepton).
proof idea
The definition is a one-line wrapper that applies gap_lepton to the input lepton.
why it matters
rs_correction supplies the universal RS term that feeds into anomalous_moment and enables the universality theorem anomalous_e_tau_universal. It realizes the phi-ladder correction for anomalous moments, where equal $Z$ forces equal residues (DOWNSTREAM anomalous_e_tau_universal doc). The parent result shows that equal $Z$ implies equal RS correction, matching the module claim of universality from equal $Z$ and the Recognition Science phi-ladder at fixed rung.
