As part of the rename to Secure Agentic Framework (SAF), all control and crosswalk identifiers changed prefix from SAFE-K8S to SAF-K8S.
Rule: SAFE-K8S-<block>-<seq> → SAF-K8S-<block>-<seq>. The 4-digit block and 3-digit sequence are unchanged; only the prefix differs.
This is a pure prefix swap across all 593 controls. Generated markdown filenames under markdown/controls/ changed correspondingly (e.g. SAFE-K8S-0101-003.md → SAF-K8S-0101-003.md).
To rewrite external references programmatically: s/SAFE-K8S/SAF-K8S/g.
