Corona is a Module-LWE threshold signature (Ringtail/Raccoon line,
ePrint 2024/1113; module dims M=8, N=7 over Z_q[X]/(X^256+1), rank>1).
Pulsar is Module-LWE (FIPS-204 ML-DSA). Neither is Ring-LWE; the "M"
in ML-KEM/ML-DSA is Module.
Fixes the 0x012206 slot-map comments (p3q, magnetar, starkfri,
modules/registerer), the Corona precompile doc comments, the registry
CORONA description string, and the README/LLM/corona-README docs.
Comments, strings, and docs only — no identifier, precompile address,
