Step 048 — Neutron as minimal stable defect
The neutron is the minimal stable defect-bundle equivalence class on the carrier: the lightest defect regime whose internal address and holonomy structure closes under the E₁ microphysical grammar.

Construction role
The neutron is the minimal stable defect-bundle equivalence class on the carrier: the lightest defect regime whose internal address and holonomy structure closes under the microphysical grammar. Beyond being one particle among others, it is the parent carrier regime from which atomic matter differentiates. Its mass supplies the sole dimensional SI calibration anchor: one dimensional scale-setting parameter that connects the dimensionless τ-internal coupling ledger to laboratory units.
What this step earns
Neutron as minimal stable defect is made addressable as Step 048 in the fine-grained Construction Spine routing layer.
- Routing scaffold. Detailed earned-output extraction is pending the source-map pass.
What this step does not yet establish
This route exposes the RC3 construction step for inspection. It does not by itself establish peer review, empirical adequacy, or final manuscript-level source closure.
