# `MishkaCmsCore.Runtime.SiteHealth`
[🔗](https://github.com/mishka-group/mishka_cms_core/blob/v0.0.1/lib/mishka_cms_core/runtime/site_health.ex#L5)

Read-only health roll-up for a single Site, for the admin Sites table's expanded
row. A Site is an aggregate (it owns Pages/Layouts/Components/ErrorPages/Stylesheets/
JsHooks + its CSS/JS bundles + a serving state), so this is a dashboard, not the
linear pipeline used per-record by `MishkaCmsCore.Runtime.RuntimeStatus`.

Signals (all cheap, computed on expand and on each realtime refresh):
  * serving state — straight off the loaded Site record, and whether it is offline: `offline_by` is
    `MishkaCmsCore.Settings.offline_by/1`, so the site's own switch and the Global one are told apart
  * compile jobs since this node booted, grouped per target into in-progress, unrecovered (the
    target's latest job failed) and recovered (failed earlier, but a later job succeeded) — one
    `oban_jobs` query matched on the site's immutable `site_id` (all jobs carry it). A job from
    before the boot is left out: the boot cancelled it and compiled from the database itself
    (`MishkaCmsCore.Runtime.Handlers.BootHandler.booted_at/0`)
  * whether the app's Oban rescues jobs a restart interrupts (`BootHandler.lifeline?/0`)
  * per-resource active/inactive/archived counts — one UNION query across the 6
    runtime tables (site-specific records only)
  * CSS/JS bundle presence + freshness — O(1) `AssetsState` ETS reads
  * recent activity — last few unified-log entries for the site (`Activity.Query`)

The derived headline is `:inactive → :offline → :attention (unrecovered) → :working (in progress)
→ :recovered → :healthy`. Red (`:attention`) is reserved for a target whose latest job
is still failed; a target that failed and then succeeded is a soft orange `:recovered`,
because a later success supersedes the old failure (a fix saved after a failed save).
