# Depeg Duration Resolver Changelog

[All versions](https://pharos.watch/methodology/depeg-resolver-changelog/)

<a id="changelog-v-2-0"></a>

## v2.0 - Sticky Public Prediction Contract

**Effective:** 2026-05-27

Replaced live DDR drift with DDRv2: one immutable public prediction or no-call at the 24h lock landmark, backed by manifest publication and append-only errata.

- Freezes one official public_prediction outcome per canonical incident key instead of recomputing public forecasts every run
- Adds pending, lock-deferred, publication-retry, no-call, frozen, and invalidated public states with live facts separated from frozen prediction payloads
- Anchors duration estimates to the lock timestamp and preserves frozen fields on stale responses while marking live overlays stale
- Moves DDRR accountability to first-published sealed outcomes and explicit coverage states rather than mutable latest snapshots
