C_net_raw
plain-language theorem explainer
The net constant for CPM coercivity is recorded as the real value 1.0 with no uncertainty band and a calibrated provenance stamp (neutrality-preserving coercivity optimization, dated 2026-01-06). Anyone assembling the CPM calibration table or checking quarantine of empirical constants cites this record. The body is a plain structure literal, not a derived proof.
Claim. The net constant for CPM coercivity is the measurement result with value $1.0$, empty uncertainty, and calibrated provenance (source note: optimized for intrinsic neutrality preservation; date $2026$-$01$-$06$; method: coercivity optimization).
background
The ambient module is the quarantine layer for empirical inputs. Certified theorem surfaces must not import raw numbers; every measured or tuned constant is wrapped so source, date, and method stay attached and auditable.
MeasurementResult packages a value of type $\alpha$, an optional real uncertainty, and a DataProvenance record. Unwrapping discards provenance and returns only the bare value. Sibling raw constants in the same file (classification and stability thresholds, projection and energy constants) follow the same pattern.
Here the constant is the net factor used in CPM coercivity bookkeeping. The provenance constructor marks it calibrated rather than raw instrument output, with an explicit optimization rationale.
proof idea
Definitional structure literal only. Fields are filled directly: value $1.0$, uncertainty none, provenance built by the calibrated constructor with the three string arguments (rationale, date, method). No lemmas, tactics, or computation.
why it matters
Feeds calibrationSummary, which lists all CPM calibration constants with provenance strings for audit. Keeps the net coercivity factor outside the certified surface while still versioned and citeable inside the measurement quarantine. Does not itself touch the forcing chain (T0–T8), RCL, or $\phi$-ladder mass formulas; it is infrastructure so those layers never silently depend on untethered floats.
