X_FROZEN_RECORD_INFERRED
Means
const X: Readonly<Record<K, V>> = Object.freeze({…}) lets the type argument be INFERRED
Typical cause
the annotation claims a closed key set and the freeze infers T from the literal, so an EXTRA key compiles in silence. Object.freeze<Record<K, V>>({…}) is the one form. This refusal carried no code until 2026-09-06
Fix
bun run frozen-records --json — write the type argument out and drop the annotation
