# GAL-2 RC5 Product Source Delta from RC3.1

Created UTC: 2026-06-10T18:51:35Z

This isolated RC5 product source is derived from the RC3.1 Time Contract product source.

RC5 product changes:
- Preserves the RC3.1 local daemon product structure.
- Updates daemon and contract identity to RC5.
- Extends Time Contract output with RC4-derived 72h holdover policy attributes.
- Adds uncertainty fields used by RC4 Extended Holdover characterization.
- Adds static IXOYE witness_ref as advisory-only out-of-band attestation reference.
- IXOYE does not affect safe_to_consume.
- IXOYE is not a fallback time source.
- GAL-2 remains the governance path.
