bvandeusenandClaude Opus 5.5	401bfb5251	fix(scheduler): a task marked not to run on startup waits an interval after boot (#5431) ... _DueTracker counted a task that had never run from 0 on the loop clock, which is host uptime, so every run_on_startup=False task (hourly data cleanup with the Docker log prune, the weekly report check, alert reconcile, agent age, Ansible schedules) fired on the first tick after each deploy, while agents were flushing their backlog. Agent ingest was slow or dropped for a few minutes after every deploy. start_scheduler now calls tracker.begin(): such a task is first due one interval after the loop starts.

bvandeusenandClaude Opus 4.8	f40063a74d	feat(reliability): fd-leak rails — self-watchdog, poll-overlap guard, fd tests ... Guardrails so the fd-leak class of bug (Errno 24 lockup; recent SNMP + UniFi fixes) surfaces early or can't compound, instead of silently killing the app. - Self-fd watchdog (steward/core/self_monitor.py): records open_fds and open_fds_pct (% of soft RLIMIT_NOFILE) as "steward"/"process" metrics each minute through the normal alert pipeline, so the operator can alert on them via the existing alert-rules UI. Built-in WARNING floor at 80% gives a zero-config early signal. Stdlib-only (/proc + resource); degrades to a no-op off Linux. Registered as a core ScheduledTask in app.py. - Poll-overlap guard (steward/core/scheduler.py): extract a pure _DueTracker that skips a tick while a task's prior run is still in flight, so a hung poll can't stack overlapping runs (which amplify per-poll resource/fd use). A skipped task isn't penalised — it retries the next tick after it completes. - fd-stability tests (tests/core/): _DueTracker overlap policy, the watchdog metric/warning/degradation paths, and a real-fd canary that hammers tcp_check and asserts /proc/self/fd doesn't grow.
