✨ Highlights

• Improved core mode Mithril v2 catch-up so Dingo keeps immutable markers, detects divergence earlier, and reconciles stale ledger state without forcing a full resync when the chain still matches.

• Added operational certificate checks for block headers and block application so forged, expired, stale, or gapped certificate data fails fast.

• Accelerated transaction lookups for MySQL and Postgres so reads complete with fewer round trips.

• Validated MySQL database names before database creation so invalid names fail early.

• Expanded the Blockfrost API with asset holder address lookups.

🧪 Testing, Docs, and Tooling

• Strengthened direct tests for ledger state application so changes in ledger processing stay covered.

• Updated the gouroboros dependency so Dijkstra and Leios support stays aligned with upstream changes.
