🏛 Phase Gamma — Proof integrity at scale (Beta→Gamma gate)

[4444J99]

Root-level phase gate for the Styx project.

All top-level Gamma-phase items are sub-issues of this gate.

This issue tracks the overall progress of the Gamma phase.

I read this as a root gate, not a code ticket. The repo already has planning and readiness artifacts, but they are spread across docs, services, and audits. The useful role for this issue is to keep Gamma reduced to one checkable sentence: do we have enough evidence for proof integrity, native bridge maturity, and trust-chain hardening, and which sub-issues are the actual blockers right now? That distilled framing is more actionable than letting the phase gate drift into a generic milestone placeholder.

Disposition for backlog governance: distilled.
