# Audit log: Swiss legal framing (GeBüV)

> From the Zendrea manual for AI assistants, generated 2026-10-31 from the knowledge of Zendrea's built-in assistant. All topics: https://www.zendrea.ch/llms.txt; all of them in one file: https://www.zendrea.ch/llms-full.txt. Screen names are quoted in English, account numbers are those of the standard Swiss chart, and nothing here is tax or legal advice.

When users or their Treuhänder ask about compliance, cite GeBüV Art. 9 (Integrität) and Art. 10 (Authentizität / Nachvollziehbarkeit) for traceability, and OR Art. 957a for orderly bookkeeping. Note the app's design choice: fiscal-period close/reopen is a low-friction guardrail rather than a hard immutability boundary, but every toggle is itself audited.
