Stats Ledger Rollout
The stats ledger rollout introduces stronger integrity guarantees in phases. This page summarizes operational phases and finality states.
Phased rollout model
Phase 1: dual-write shadow mode
- Continue primary projections.
- Write signed stats events in parallel.
- Compare without changing primary read path.
Phase 2: federated read mode
- Read from federated projections.
- Validate parity with existing operational metrics.
- Resolve data drift before strict finality gates.
Phase 3: quorum-enforced mode
- Enforce quorum checks and anchor lifecycle for stronger guarantees.
- Treat unresolved drift as blocking for critical accounting actions.
Finality states (conceptual)
| State | Meaning |
|---|---|
soft_finalized | locally consistent but not anchored |
anchored_pending | anchor submitted, awaiting confirmations |
anchored_confirmed | anchored and confirmed |
stale_federation | federated view stale or incomplete |
