Worked on the nspcc-dev/neofs-node repository, focusing on backend development and smart contract logic using Go and Markdown. Addressed a bug in the N3 script verification process by ensuring that a persisted block number is returned for BlockHeight compensation scenarios, which enhances verification accuracy and reliability. The technical approach involved adjusting the index of a fake block header used during script verification to better align with compensation requirements. Additionally, updated the CHANGELOG.md to document the fix and its rationale, supporting clearer release notes and traceability. The work concentrated on targeted bug resolution rather than feature development during this period.
