The whitelist is now derived live from notification_channels.CHANNEL_TYPES, so adding a new channel implementation cannot silently regress this validator again",

The polls are now staggered (latency, then CPU temperature, then disk SMART) while preserving the per-disk 60 s cadence",

It now reads /proc/<lxc-start-pid>/task/<lxc-start-pid>/children directly and falls back to lxc-info only when /proc reads fail, eliminating one subprocess per CT per scan cycle",

The dashboard now dispatches a `health-suppression-changed` browser event on every dismiss / un-dismiss; the Settings page listens for it (plus window focus and document visibilitychange) and re-fetches the active set",

+"""Sprint 14: per-disk temperature history.
+
+Mirrors the CPU ``temperature_history`` infrastructure in flask_server,
+but keyed by disk name so each physical drive gets its own time series.
+Same SQLite DB (``/usr/local/share/proxmenux/monitor.db``), same 30-day
+retention, same downsampling buckets the CPU history endpoint uses
+(hour=raw / day=5min / week=30min / month=2h).
+
+The sampler is a single function meant to be called once per minute
+from flask_server's existing ``_temperature_collector_loop``, so we
+don't add another background thread.
+
+Performance — three caches keep the steady-state cost flat on big JBODs:
+
+  * ``_disk_list_cache``    — lsblk + USB filter, refreshed every 5 min.
+  * ``_disk_probe_cache``   — remembers which ``smartctl -d <type>``
+                              variant works for each disk so we skip
+                              the 4-attempt fallback chain.
+  * ``_disk_fail_backoff``  — drives that never report a temperature
+                              are rate-limited to one re-probe per hour
+                              instead of every minute.
+
+The actual smartctl calls run in a ThreadPoolExecutor, so a 24-disk host
+spends ~max(per-disk time) per sample instead of sum.

+"""User-configurable Health Monitor thresholds.
+
+Until now every threshold the Health Monitor (and the notification stack
+that hangs off it) compares against was a hardcoded constant in
+``health_monitor.py`` and a few helper modules. Operators repeatedly
+asked for the ability to tune them per host — for example, a small
+homelab user is fine with the rootfs filling to 92 % before being
+nagged, while a production node owner wants the alert at 80 %.
+
+This module is the single source of truth for those thresholds. The
+JSON file at ``/usr/local/share/proxmenux/health_thresholds.json``
+holds only the *overrides* the user has made; anything missing falls
+back to the recommended default below. That keeps forward compatibility
+trivial: new thresholds added in a later version are absent from older
+JSON files and just resolve to their recommended value.
+
+Public surface:
+
+    DEFAULTS          — nested dict of recommended values + per-field metadata
+    get(section, key) — read effective value (override or default)
+    load()            — return the user-configured overrides (no defaults applied)
+    load_effective()  — return a fully-merged config (defaults + overrides)
+    save(payload)     — validate & persist a partial or full config
+    reset_section(s)  — clear all overrides for one section
+    reset_all()       — wipe every override
+    invalidate_cache()— force the next ``get`` to re-read from disk
+
+Every public function is safe to call from request handlers and from
+the background health collector concurrently. A 5-second in-memory
+cache avoids disk reads on the hot path; the cache is invalidated on
+save/reset.

+"""Sprint 13.29: per-LXC mount points enumeration.
+
+The Mount Points tab in the LXC modal calls
+``GET /api/lxc/<vmid>/mount-points`` which delegates here. We parse the
+container config (``/etc/pve/lxc/<vmid>.conf``) for ``mpX:`` entries —
+the rootfs is intentionally excluded (the user asked for *user-added*
+mounts, not the container's own disk).
+
+Each ``mpX:`` is classified into one of three types based on the source
+syntax:
+
+  * ``pve_volume`` — ``storage_id:vol-id`` (block device assigned from a
+    PVE storage; appears as a separate volume, not a path)
+  * ``pve_storage_bind`` — absolute path under ``/mnt/pve/<storage>``
+    that resolves to a registered PVE storage (typical NFS/CIFS share
+    bound into the container)
+  * ``host_bind`` — any other absolute path on the host
+
+For each entry we resolve the source-side capacity (so the value is
+available even when the LXC is stopped) and, when the LXC is running,
+enrich with runtime fields read from ``/proc/<pid>/mounts``: the
+filesystem actually mounted on the target, mount options, and a
+stale-detection stat with timeout.
+
+Ad-hoc mounts done inside the container (NFS/CIFS mounted from inside
+the CT, not via ``mpX:``) are listed alongside the configured ones with
+a ``ad_hoc`` type so the user sees the complete picture.

+"""Sprint 13: detect remote mount issues that PVE storage monitoring misses.
+
+Parses ``/proc/mounts`` filtering NFS/CIFS/SMB entries, then for each
+one runs a timeout-bounded ``stat`` to catch stale handles. Stale NFS
+is the typical failure mode that broke a user's LXC: the mount looks
+present in ``/proc/mounts`` but any access either blocks indefinitely
+or returns ``ESTALE``. Meanwhile any app in the LXC that keeps writing
+to that path appends to the underlying directory on the local
+filesystem (because the mount is effectively gone), which silently
+fills up the LXC's root disk and eventually kills the container.
+
+This module sits next to ``proxmox_storage_monitor.py`` (which only
+covers PVE-registered storages) and complements it for arbitrary
+remote mounts done outside PVE (e.g. ``/etc/fstab`` entries, ad-hoc
+``mount -t cifs``, etc.).
+
+Scope for Sprint 13:
+- Host-only. Mounts done inside running LXCs are out of scope —
+  reaching them needs ``pct exec`` per container which is slow and
+  can hang on a corrupted guest. That's tracked as a follow-up.
+- Detects: stale (timeout/ESTALE), unexpected read-only, plain
+  reachable.

+"""Sprint 12A: Detect ProxMenux post-install function updates.
+
+Parses /usr/local/share/proxmenux/scripts/post_install/{auto,customizable}_post_install.sh,
+extracting the ``# version: X.Y`` and ``# description: ...`` comments
+declared inside each top-level function. Compares the parsed versions
+against the per-tool entries in ``installed_tools.json`` and returns the
+list of tools where the on-disk script has bumped past what the user
+installed.
+
+The detection runs once at AppImage startup, before the rest of the
+update-check pipeline kicks in, and the result is cached in memory and
+persisted to ``updates_available.json`` so the bash menu and the
+notification poller can read it without re-parsing.
+
+Backward compatibility: ``installed_tools.json`` was originally a flat
+dict of ``{key: bool}``. Sprint 12A adds the structured
+``{key: {installed, version, source}}`` shape. Legacy booleans are read
+as installed (true) at version ``1.0`` with source unknown. Unknown
+source means the detector still flags an available update, but the UI
+falls back to asking the user which flow (auto vs custom) to run.
