Four HTTP handlers iterated sql.Rows without calling rows.Err() after the loop, silently swallowing mid-stream Postgres/network errors:

  • ListEvents / ListByWorkspace (events.go)
  • ListChannels (channels.go)
  • HandleTelegramWebhook (channels.go)
  • List (memory.go)

Added rows.Err() checks after each loop so iteration errors are logged rather than silently truncating results returned to callers.

Five-axis review for PR #1708.

Correctness: APPROVED. The four list/webhook handler loops now check rows.Err() after rows.Next(), making mid-stream Postgres/network iteration failures visible instead of silently returning truncated events, channels, webhook candidates, or memory rows. This matches the PR scope.

Robustness: this preserves existing best-effort HTTP behavior while adding operational signal for partial result sets. No destructive mutation path is involved, so logging-only handling is acceptable here.

Security: no new inputs, auth paths, SSRF surface, or secret handling. The logs contain handler context and row iteration errors only.

Performance: constant rows.Err checks after existing loops; no new queries, nested loops, or blocking I/O.

Readability: small, localized, idiomatic Go checks with clear subsystem-specific log messages.

CI/status checked on b9efc82: statuses are accessible; all-required, Platform Go, lint, secret scan, and E2E contexts are green. Aggregate status is held by approval gates, and the PR is mergeable=false/rebase-needed.

Peer 2nd-review per CTO carve-out. 5-axis lens clean; deferring to Code Reviewer (2) review_id=5581. Note: PR is mergeable=false (rebase-needed) — approvals valid, but Kimi must rebase the branch on main before merge. BP unblock once rebased.
