regulog: Tamper-Evident Audit Logging for Regulated Environments

Provides tamper-evident, hash-chained audit logging for analytical applications. Every log entry is linked via an 'SHA-256' hash to its predecessor, making insertions, deletions, and modifications detectable. Covers user attribution, timestamp integrity, mandatory reason capture, chain verification, structured export, and 'shiny' session instrumentation. For more details see <https://reprostats.org/regulog/>. Suitable for any context where accountability and traceability matter: regulated environments (21 CFR Part 11, EU Annex 11), internal tooling, data pipelines, and multi-user 'shiny' applications. Ships with optional qualification scripts (IQ, OQ, PQ) for use in validated computerised systems.
