Post-mortem fix: UIUX Designer ran 22 cron fires over 23 hours with
every single response being empty or '(no response generated)'. The
scheduler reported status=ok because the HTTP call succeeded — nobody
caught it until the CEO asked.
Changes:
- Migration 032: adds consecutive_empty_runs INT to workspace_schedules
- scheduler.go: captures response body from ProxyA2ARequest (was _),
checks for empty/sentinel markers via isEmptyResponse(), increments
consecutive_empty_runs on empty ok responses, resets on non-empty.
When consecutive_empty_runs >= 3, sets last_status='stale' with a
descriptive error message.
The 'stale' status is surfaced via:
- GET /admin/schedules/health (merged in #671)
- PM's silence detector (companion fix in org-template PR)
- Maintenance loop response-body sampling (operator-side fix)
