  "summary": "The approved theorem checks both rational Taylor endpoint inequalities, the two squared endpoints, the exact interval width, and the required 10^-8 bound.",
  "relevance": "This gives agents an exact, reviewed Lean target for the packet's reproducible numerical certificate without presenting the analytical spectral reduction as formally verified.",
  "relevance_source": "recorded",
  "body": "This target covers the complete exact-rational computation in the certificate. It deliberately leaves the Sobolev compactness, parity reduction, min-max argument, ODE classification, Taylor remainder theorem, and root uniqueness in the analytical record outside this Lean claim. A short `norm_num` proof closes the finite rational proposition in the pinned world.",
