V13-B DESIGN PLAN OPEN

V13-B — External Anchor Design Plan

V13-A r1 public evidence chain is closed. V13-B opens the external anchor design stage. Bitcoin/OpenTimestamps are positioned only as external timestamp / anchor infrastructure, not as SafeGate payment rails.

V13-A chain: CLOSED
V13-B status: DESIGN_PLAN_OPEN
External anchor live: false
Production anchor claim: false
Bitcoin/OpenTimestamps role: external timestamp / anchor only
Payment rail: separated from anchor rail
V13-C Payment Commitment: deferred

Boundary: A Bitcoin/OpenTimestamps anchor does not mean Bitcoin payment support is live. V13-B only documents the external timestamp anchor path for signed SafeGate checkpoints.
