Variable: FATAL_CODES

const FATAL_CODES: object

Stable string codes for every Tier-3 fatal the parser may throw.

Locked at four codes per PROJECT.md "Fatal errors only for unrecoverable structural corruption": anything less severe MUST be a Tier-2 warning (see ./warnings.ts). Consumers narrow on err.code to react to specific structural failures.
