 - [x] **NS-05** Drop redundant `actions/setup-go` from `.gitea/workflows/ci.yml`. ✅ Already gone — verified `.gitea/workflows/ci.yml` has zero `actions/setup-go@v5` invocations and no `GO_VERSION` env; the file's header comment now documents that the runner image (`gitea.dcglab.co.uk/steve/ci-runner-go`) is the single source of truth for the Go version. Closing as done; no further code change needed.
 - [x] **NS-06** Remove the permanently-disabled "Run backup now" button from `web/templates/partials/host_chrome.html`. ✅ Landed: dropped the disabled tombstone button from the host header action row; only "Edit credentials" + the ⋯ menu remain. Per-source-group Run-now on `/hosts/{id}/sources` is the only path now. No e2e change needed — `smoke.spec.ts` does not assert on host_chrome's button row.
 - [x] **NS-07** Relative timestamps go stale on long-open tabs. ✅ Landed: `formatRelTime` now wraps its label in `<time data-rel-ts=…>` and both layouts (`base.html`, `chromeless.html`) carry a small ticker that re-renders every 30s, so a page rendered an hour ago no longer keeps showing "2h ago" when the wall-clock truth is "3h ago". Covered by `funcs_test.go`. The bug: every relative label was computed once at server render and never updated client-side, so a job-detail page left open drifted further from reality the longer it sat.
+- [x] **NS-08** Always-On vs intermittent host mode. ✅ Landed: a host can now be marked not-always-on (laptop/workstation) so it stops generating offline-alert noise when it legitimately sleeps. Migration 0024 adds `hosts.always_on` (default 1 = today's 24×7 behaviour; intermittent is strictly opt-in). The alert engine suppresses `agent_offline` for intermittent hosts and instead wires up the previously-dead `stale_schedule` alert for them — raised at a 7-day global threshold when the host has an enabled schedule and a stale last backup, resolved on the next successful backup. A new server-side catch-up scheduler (`internal/server/http/catchup.go`) arms on agent hello and fires from the existing 30s pending-drain tick: ~60s after an intermittent host reconnects it dispatches a backup for any enabled schedule whose window elapsed while asleep (overdue = `cron.Next(lastBackup) <= now`, reusing the shared `cronParser`), guarded against firing when the host bounced offline, flipped to always-on, or already has a job running. Overdue is measured against the per-host `LastBackupAt` (exact for the common single-schedule laptop; a known coarseness for multi-cadence hosts, documented in code). Operator toggle via `POST /hosts/{id}/mode` (audited `host.mode_updated`), which also clears open offline/staleness alerts so the next sweep re-settles. UI: intermittent offline hosts render a calm grey `asleep · <relTime> · will catch up on return` state (new `.dot-asleep`) instead of red "offline"; a `24×7` chip shows only for always-on hosts; a "presence" inline toggle on the host header. Design + plan in `docs/specs/2026-06-15-always-on-host-mode-design.md` and `docs/plans/2026-06-15-always-on-host-mode.md`. Spec §2 (online/offline mechanics) deliberately left untouched. Out of scope for v1: per-host staleness thresholds, continuous (non-reconnect) overdue evaluation, per-schedule last-success tracking.
 - [x] **NS-04** Dashboard parity with the alerts screen: live refresh, column sorting, filters. ✅ Landed: `/` now parses `q`/`status`/`repo_status`/`tag`/`sort`/`dir` query params (round-trip durable for bookmarks); table is wrapped in an `id="hosts-table"` htmx live-poll matching the alerts cadence (5s, gated on `document.visibilityState` and `localStorage.rm-dashboard-live`); filter row above the table with hostname free-text + status + repo_status selects + tag chips + clear; column headers (Host / OS · arch / Last backup / Repo size / Snapshots) are clickable links that toggle direction on the active column; pure-Go sort+filter pipeline covered by `dashboard_filter_test.go`. Original scope below. live refresh, column sorting, filters. The host list is currently a static render — operators have to reload to see new heartbeats / job state changes. Mirror the alerts pattern (`web/templates/pages/alerts.html` uses `hx-trigger="every 5s [document.visibilityState==='visible' && localStorage.getItem('rm-alerts-live')!=='off']"` plus a Live/Off toggle so background tabs and explicit-off don't burn server cycles). Add: server-side sort on every meaningful column (name, OS, last-backup time, last-backup status, agent online/offline, restic version, tags), and a small filter row above the table — at minimum free-text on hostname, status (online/offline/never-seen), and tag chips. Columns + filter state should round-trip through query string so a bookmarked / shared URL is durable. Re-use the `host_row` partial that already exists so the live-refresh swap is a clean OOB swap, not a full table re-render.
