SOLVER EXECUTED · ZERO RESIDUAL

context
WHAT THIS CERTIFICATE RECORDS, IN PLAIN TERMS. The problem: Cospectral Nonisomorphic Graph Witness. This is the SOLVER-EXECUTED version from the Copilot Created store, superseding the earlier scan of the same job. The classical reading projects the complete object to a report — graph -> adjacency characteristic polynomial coefficients. The MuncyNautics Seam Recovery Method names the lost channels, keeps both arms, and reworks the governing equation — Recover the cospectral graph class; add structural invariants or a stronger measurement lane before claiming graph isomorphism.. Falsifier: { "test": "Require distinct witnesses, reconstruct both reports independently, and reject on any nonzero residual.", "result": "PASS" }. Method: Derrick E. Muncy.

correction_rule
Correction = reconstruction from the recovery: restored arguments, seats, phases and arms in the equation itself. No raw appended constants; any finite term must be derived from the recovered channels, never fitted.
phase_retained
True
reworked_equation
Recover the cospectral graph class; add structural invariants or a stronger measurement lane before claiming graph isomorphism.
