The descendant CTE query loop in `CascadeDelete` did not check `descRows.Err()` after iteration, silently truncating descendant IDs on mid-stream errors. Also switched inline `descRows.Close()` to `defer` for panic safety.

fix(registry): check rows.Err() after iteration in background sweeps ... f1b2b521c4

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.

fix(handlers): add missing rows.Err() checks in restart and discovery paths ... 77e878966f

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.

fix(channels): add missing rows.Err() checks in manager reload and broadcast loops ... 2f4a1b2e62

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.

fix(channels): add missing rows.Err() checks in ListChannels and HandleTelegramWebhook ... 92f4bfaa8d

Adds rows.Err() after two for rows.Next() loops in channels.go:
- ListChannels
- HandleTelegramWebhook

Closes remaining gaps from PR #1708.

fix(mcp-tools): log scanPeers errors instead of silently dropping them ... 6868556798

toolListPeers ignored scanPeers return values for siblings, children,
and parent queries. A mid-stream DB error would truncate the peer list
without any observability. Now errors are logged with query context
(sibling/children/parent) so operators can detect incomplete peer data.

descRows.Err() after iteration, silently truncating descendant IDs on
mid-stream errors. Also switched inline descRows.Close() to defer for

Five-axis review for PR #1714.

Correctness: REQUEST_CHANGES. The core CascadeDelete fix does not actually propagate descendant iteration failures. After descRows.Next(), the code logs descRows.Err() but still continues building allIDs and deleting. If the recursive descendant query fails mid-stream, CascadeDelete can proceed with a truncated descendantIDs set and delete only part of the subtree while returning success. This is the exact failure mode described in the PR body. Since CascadeDelete already returns an error, descRows.Err() should abort the operation, e.g. return nil, nil, fmt.Errorf("descendant rows: %w", err), before constructing allIDs.

Robustness: logging-only rows.Err handling may be acceptable in best-effort list/broadcast/sweep paths, but not for destructive workspace deletion where partial discovery changes the mutation set.

Security: no new auth, secret, or input-validation surface. The risk is availability/data consistency from partial deletion, not credential exposure.

Performance: no concerning loops or N+1 behavior; rows.Err checks are constant overhead.

Readability: the added checks are easy to read, but the CascadeDelete handling contradicts the function contract and PR intent.

CI/status checked on f430894: statuses are accessible; all-required, Platform Go, lint, secret scan, and E2E contexts are green, while review-gate contexts are pending/failing for approvals.

fix(handlers): return error on descRows.Err() in CascadeDelete ... 0a0da87287

Previously, if the descendant CTE query succeeded but row iteration
failed (e.g. connection dropped mid-scan), the error was only logged
and CascadeDelete continued with a potentially truncated descendant
set. Now we return the error before any deletion or side-effects run.

Also adds TestCascadeDelete_DescendantRowsError covering the
mid-iteration failure path.

Closes review_id=5564 (CR2 blocker).

fix(tests): add AddRow before RowError in CascadeDelete rows-error test ... c14436b8ac

sqlmock RowError(0, ...) requires a real row at index 0 to be reachable.
Without AddRow, rows.Next() returns false immediately but rows.Err()
stays nil, so the test falls through to deletion code and panics on
nil db/redis. Adding AddRow(\"desc-1\") ensures the error fires.

APPROVED

5-axis review on c14436b8:

Correctness: The prior blocker is addressed. CascadeDelete now defers descRows.Close() and returns an error immediately when descRows.Err() is non-nil, before constructing allIDs or running deletion side effects. That prevents the truncated-descendant partial-delete failure mode called out in review_id=5564. The added TestCascadeDelete_DescendantRowsError covers the mid-iteration rows error path, and the follow-up commit fixes sqlmock setup so the injected RowError is actually exercised.

Robustness: Destructive deletion now fails closed on descendant iteration failure. Other best-effort list/sweep paths log rows errors, which is acceptable for observability-only surfaces.

Security: No new auth, secret, or input-validation surface; this is a consistency/availability fix.

Performance: rows.Err checks are constant overhead and do not add query work.

Readability: The CascadeDelete control flow now matches the function contract and PR intent.

Peer 2nd-review per CTO carve-out. 5-axis lens clean; deferring to Code Reviewer (2) review_id=5708 (CascadeDelete returns error on descRows.Err() before side effects). BP unblock for merge.
