## What This Release Demonstrates

GAL-2 RC5 extends RC4-derived governed Time Contracts with a real IXOYE out-of-band solar witness attestation layer.

GAL-2 governs application-facing Time Contracts.

IXOYE witnesses from outside the governed path.

The IXOYE witness layer publishes hash-chained attestations that can be independently verified.

## What This Release Does Not Claim

GAL-2 RC5 does not replace UTC, GNSS, PTP, NTP, chrony, atomic clocks, hardware clocks, timing cards, grandmasters, or oscillators.

IXOYE is not a fallback time source for GAL-2.

IXOYE does not decide safe_to_consume.

GAL-2 does not read IXOYE output during Time Contract generation.

## Verify

Run:

```bash
shasum -a 256 "GAL2_RC5_IXOYE_WITNESS_RUN_20260610T161352Z_FINAL_EVIDENCE_PACKAGE.tar.gz"
tar -xzf "GAL2_RC5_IXOYE_WITNESS_RUN_20260610T161352Z_FINAL_EVIDENCE_PACKAGE.tar.gz"
python3 GAL2_RC5_IXOYE_WITNESS_RUN_20260610T161352Z/verifier/rc5_ixoye_witness_chain_verifier.py --log GAL2_RC5_IXOYE_WITNESS_RUN_20260610T161352Z/witness/ixoye_real/attestations/ixoye_attestations_rc5.jsonl --head GAL2_RC5_IXOYE_WITNESS_RUN_20260610T161352Z/witness/ixoye_real/attestations/head.json --min-records 7

Expected result:

VERDICT=PASS

## Canonical Summary

GAL-2 governs. IXOYE witnesses. The daemon enforces. The API distributes governed Time Contracts.

RC4 remains preserved as prior holdover evidence. RC5 supersedes RC4 as the current witness-layer evidence release.
