# EDEN timeclock skill

## When to use
- Implementing/reviewing Control iD device communication → `references/controlid.md`.
- Implementing/reviewing AFD parsing, CRC validation, or the apuração engine → `references/afd-671.md`.

## Rule
`afd_records` (raw punch data) is immutable — no UPDATE/DELETE route, ever, at any privilege level. See `eden-hr-timeclock` agent for the full non-negotiable invariant list.
