FinestVX

Status: Alpha -- under development. The API is not stable.

FinestVX is a headless, country-agnostic bookkeeping core engine. The goal is an embeddable double-entry ledger that can serve as the financial backbone of larger application.

FinestVX treats FTLLexEngine as a platform dependency, not a copy source: locale normalization, localization boot integrity, raw reverse parsing, and FluentNumber construction come from FTLLexEngine directly, while FinestVX keeps only bookkeeping-specific orchestration on top.

Vision

• Double-entry ledger with zero-sum enforcement per currency per transaction
• Append-only audit trail -- corrections via contra-transactions, never edits
• Multi-currency -- any ISO 4217 currency; non-January fiscal years
• Legislative plugins -- jurisdiction rules loaded as isolated, crash-contained plugins
• SAF-T / XBRL export -- XML artifacts with XSD validation
• PDF reports -- balance sheet and P&L
• Strict financial arithmetic -- Decimal throughout; no float on any monetary path
