Sorry, something went wrong.
Squash of PR #1121 rebased onto main after #1130 (governance singleton), with fold adjustments to remove the overlap between the two: - DRepState.first_seen_at moves from CBOR index 8 to 9 (8 is taken by the phase-3 expiry field on main) - DRepSeen is appended after GovDormancyReset in CardanoDelta so the WAL variant positions of the merged gov deltas stay untouched - the DRepRegistration prev_anchor/anchor-apply edit is dropped: the delta's released WAL shape is frozen, and main already persists the registration anchor via DRepAnchorUpdate on every RegDRepCert (#1128) - compat tests extended to prove index-9 decode behavior for legacy rows Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

- Around line 377-380: Update the first_seen_at initialization logic to choose
the earlier reference between the existing registered_at value and the current
(self.slot, self.txorder) sighting, preserving existing first_seen_at values.
Add a regression test covering a legacy row with registered_at set and
first_seen_at unset, followed by a later certificate.

Preserve the earliest known reference for legacy state.
A legacy row can have registered_at = Some((100, 0)) and first_seen_at = None. If a later certificate is processed at (200, 0), this code stores (200, 0) as the first sighting. That value conflicts with the documented first on-chain reference contract.
Use the earlier of registered_at and the new sighting when initializing first_seen_at. Add a regression test for this upgrade path.
Proposed fix
if entity.first_seen_at.is_none() {
- entity.first_seen_at = Some((self.slot, self.txorder));
+ let seen_at = (self.slot, self.txorder);
+ entity.first_seen_at = Some(
+ entity
+ .registered_at
+ .map_or(seen_at, |registered_at| registered_at.min(seen_at)),
+ );
