Summary
rows.Err()check after thefor rows.Next()loop inlistDelegationsFromLedger()inworkspace-server/internal/handlers/delegation.gobc9cf599) onto the delegations-list-ledger-fallback branchrows.Err()contract violation where mid-stream DB errors (e.g. dropped connection) were silently ignoredTechnical Details
The
database/sqlcontract requires callingrows.Err()after exhausting the rows iterator viafor rows.Next(). The existinglistDelegationsFromActivityLogsalready had this check; this fix adds it tolistDelegationsFromLedgerfor consistency.The check is non-fatal (logs and continues) to preserve partial results where possible.
SOP Checklist
rows.Err()contract violation, not masking a symptomrows.Err()properly called. Readability: consistent with existinglistDelegationsFromActivityLogs. Architecture: same pattern as sibling function. Security: no secret/auth logic touched. Performance: no runtime path changed.bc9cf599on main is the same pattern applied to the sibling function.🤖 Generated with Claude Code

⚠️ ESCALATION: Syntax error blocking PR merge — 4+ commits, author unresponsive
PR #882 has a Go syntax error in
delegation_test.gothat has persisted across 4+ commits without fix:t.Errorf("unmet sqlmock expectations: %v", err) (fix(delegations): ListDelegations falls back to delegations table before activity_logs)(fix(delegations): ListDelegations falls back to delegations table before activity_logs)These are dangling commit message fragments after

Reviewed PR #882. The fallback chain and error handling are correct:
listDelegationsFromLedger: Queries the durable
delegationstable with proper scanning. Query error returnsnilsilently — correct for pre-migration case where the table may not exist.rows.Err() check (the fix): After
rows.Next()loop,rows.Err()catches any iteration error (connection drop, etc.). Without this check, iteration failures were silently ignored.log.Printfprovides visibility without failing the request — falls through to activity_logs as a bonus.Fallback chain:
ledger → activity_logscovers both new (post-#318) and legacy delegation data correctly.defer rows.Close()ensures clean resource cleanup.listDelegationsFromActivityLogs: Preserved as the legacy fallback path. Handles both post-migration (ledger empty) and pre-migration (no ledger table) cases.
