API access

• Added page by page transaction retrieval to GET /api/v0/blocks/latest/txs. The endpoint checks count, page, and order, returns pagination headers, preserves the requested ordering, and returns an empty page when a request falls outside the available results.

Synchronization and peer governance

• Improved ChainSync and peer governance by measuring blockfetch peer performance, prioritizing configured roots, backing off stalled peers, recovering after a resynchronization, and cooling down inbound connections by host.

State queries

• Isolated LocalStateQuery sessions with snapshots, a configurable maximum session lifetime, and explicit errors when a required dependency is unavailable.

Mithril recovery

• Hardened Mithril backfills by selecting correct anchors, checking archives and proofs, enforcing configurable download limits, and rejecting invalid artifacts.

Peras

• Introduced the Peras package and conformance scaffold.

Parity checks

• Enhanced koios-parity retries and significant mismatch reporting, giving transient failures additional attempts and making material differences visible.

Ledger validation

• Corrected ledger validation for era rules, fee and deposit accounting, malformed hashes, Byron replay behavior, and overflow handling.
