March 2026: Delivered robust deletion semantics for snapshots and improved update handling in erigon. Implemented idempotent snapshot deletions to prevent nil-pointer crashes when target segments are absent, canceled stale DeleteUpdate operations during storage rewrites, and added regression tests for delete-then-write semantics and duplicates/non-existent deletions. These changes reduce crash risk, improve data integrity, and lower operational risk in the storage layer. Tech debt payoff and maintainability improved through added tests and clear commit messages.
