Adds rows.Err() after three for rows.Next() loops in channels/manager.go:

  • pausePollersForDiscovery
  • Reload
  • BroadcastToWorkspace

Without these, mid-stream query errors silently truncate the channel list, leaving stale pollers running or skipping broadcast targets.

Adds `rows.Err()` after three `for rows.Next()` loops in `channels/manager.go`: - `pausePollersForDiscovery` - `Reload` - `BroadcastToWorkspace` Without these, mid-stream query errors silently truncate the channel list, leaving stale pollers running or skipping broadcast targets.

sweepOnlineWorkspaces and sweepStaleRemoteWorkspaces (healthsweep.go)
and sweep (provisiontimeout.go) iterated sql.Rows without calling
rows.Err() after the loop. A mid-stream Postgres error would silently
truncate the candidate list, causing missed offline-marking or missed
provision-timeout failures.

Adds rows.Err() after rows.Next() loops in three handlers:
- restart_context.go: global_secrets + workspace_secrets queries
- workspace_restart.go: Pause/Resume descendant CTE queries
- discovery.go: queryPeerMaps peer listing

Also switches restart_context.go from inline rows.Close() to defer
rows.Close() for panic safety (matches pattern in healthsweep.go).

These close the remaining gaps from PR #1704 and #1708.

Five-axis review for PR #1712.

Correctness: APPROVED. The manager loops now check rows.Err() after iteration in pause-pollers, Reload, and BroadcastToWorkspaceChannels, making mid-stream DB errors observable instead of silently truncating channel/poller/broadcast state. The extra rows.Err logging in related restart/sweep paths is also consistent with best-effort operational flows.

Robustness: this improves diagnosis of partial query results without changing existing best-effort behavior. None of the touched paths has the destructive all-or-nothing contract that would require aborting before mutation.

Security: no new input, auth, SSRF, or secret-handling surface. Log output is operational error context only.

Performance: constant rows.Err checks after existing result iteration; no new query patterns, loops, or blocking I/O.

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

CI/status checked on 2f4a1b2: statuses are accessible; all-required, Platform Go, lint, secret scan, and E2E contexts are green. Aggregate status is held by approval-gate contexts.
