Tamper-evident, hash-chained ledger

Every operational event is written once and never edited. Each record carries a SHA-256 hash computed over its own content plus the previous record's hash. Altering any past event breaks every downstream link — tampering is mathematically detectable.

No protected health information leaves the operational layer — the ledger records identifiers and decisions, not clinical records. Exports are complete and audit-ready for LGPD and HIPAA-aligned review.
