Status: public evaluator / enterprise pilot candidate
Runtime source: RC5.1 / 1.1.3 source with validity, deadband, and observability fixes

Boundary:
- GAL-2 governs Time Contracts
- IXOYE witnesses out-of-band as advisory-only reference
- IXOYE is not a fallback time source
- IXOYE does not decide safe_to_consume
Witness discovery endpoint is not available in RC5.1. Attestation serving ships separately in RC5.2.

Known RC5.2 targets:
- Signed IXOYE attestation chain
- attestation_chain_head in contract
- 24h/72h clean run after 1.1.3
- enterprise runbooks
- latency SLO characterization
