Context
Chen–Kricker already proved the two named trace identities through their comparison module. Making the comparison invertible upgrades that diagram to an isomorphism statement.
Hypotheses and scope
- All traces use Chen–Kricker's stated common conventions.
- Only the extended target covered by their theorem is compared.
Proof or evidence
Chen–Kricker's two established trace identities factor through the comparison map; FPRD-CK-T01 makes that map invertible.
Verification notes
The research record tracks the normalized Panitch–Park branch, Weyl factors, central opposite-root quotient and the noninvertible discarded minus sector.
Limitations
- The later supporting local-collar packet supplies the named six-root peripheral action at generic parameter; no integral-coefficient or special-parameter extension is asserted.
- Raw Garoufalidis–Yu-index coordinates are not silently identified with Chen–Kricker's convention-adjusted trace.
- Panitch–Romo Conjecture 7.1 remains open.
