"""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.

etc.) is one entry in DETECTORS + one entry in CHECKERS.
Two operation modes:
* **Detection** — at AppImage startup and every 24h, every registered
``DETECTOR`` runs against the host. If the probe finds the thing
installed and it's not in the registry, we add it (with
``installed_by="detected"`` so the operator sees we autodiscovered
it). If it's in the registry but the probe fails, we mark it
``removed_at`` instead of deleting — keeps history and avoids
spurious notifications when a probe transiently fails.
* **Update check** — for every active entry, the matching ``CHECKER``
runs and updates ``current_version`` + ``available`` + ``latest``.
Each checker is responsible for its own per-source cache (the
Tailscale OCI checker memoises for 24h, NVIDIA for 7 days). The
notification poll loop reads the registry, emits a notification when
``available`` flips false→true for a (type, latest) pair it hasn't
notified yet.
Persistence is a single JSON file at
``/usr/local/share/proxmenux/managed_installs.json``. Atomic writes
via tmp+rename so a crash mid-write can't leave a half-written file.
The module is concurrency-safe: a single ``threading.RLock`` guards
every read-modify-write so the periodic detector and a request handler
calling ``get_registry()`` can run in parallel without stepping on
each other.

"""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.

# older than the upstream one?). Returns the current/latest pair.
# The raw probe takes ~2 seconds inside the CT, so we cache the
# result for 24 h (per app_id) — the periodic notification poll
# and the UI re-uses the same cache.

# * `update_app(app_id)` — applies the upgrade. Runs `apk upgrade`
# so Alpine + tailscale + libs all roll forward together. If the

"""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.
