Pulse was generating tag colours from a hash of the tag name instead
of using the colours configured in Proxmox. Now polls /cluster/options
once per PVE instance and merges the tag-style colour map into state,
which the frontend uses as the first-priority colour source for tag
badges. Falls back to the existing special-tag and hash-based colours
when Proxmox hasn't set a custom colour for a tag.
Proxmox status.Mem includes page cache as "used" memory, inflating
reported VM usage. The existing fallbacks (balloon meminfo, RRD, linked
host agent) were frequently unavailable, causing most VMs to fall
through to the inflated status-mem source.
Adds a new last-resort fallback that reads /proc/meminfo via the QEMU
guest agent file-read endpoint to get accurate MemAvailable. Results
are cached (60s positive, 5min negative backoff for unsupported VMs).
Also fixes: RRD memavailable fallback missing from traditional polling
path, cache key collisions in multi-PVE setups, FreeMem underflow
guard inconsistency, and integer overflow in kB-to-bytes conversion.
Backport of v6 commits a87c9950 and 347d7db1.
Part 1 (a87c9950): Wrap the four guest agent c.get() errors with
fmt.Errorf("guest agent ...: %w", err) so isVMSpecificError() correctly
scopes them to the VM rather than the cluster endpoint.
Part 2 (347d7db1): Replace the 20+ pattern blocklist in
executeWithFailover with an allowlist via isEndpointConnectivityError().
Only true TCP/DNS/TLS failures mark an endpoint unhealthy. Any HTTP
response from Proxmox — including 500 — proves the node is reachable
and returns the error without affecting endpoint health.
Linux VM page cache (#1270): QEMU VM memory now falls back to Proxmox
RRD's memavailable metric (which excludes reclaimable page cache) when
the qemu-guest-agent doesn't provide MemInfo.Available. Previously the
fallback was detailedStatus.Mem (total - MemFree), inflating usage to
80%+ on VMs with normal Linux page cache. Mirrors the existing LXC
rrd-memavailable path.
FreeBSD ZFS ARC (#1264, #1051): The host agent now reads
kstat.zfs.misc.arcstats.size via SysctlRaw on FreeBSD and subtracts
the ARC size from reported memory usage. ZFS ARC is reclaimable under
memory pressure (like Linux SReclaimable) but gopsutil counts it as
wired/non-reclaimable, causing false 90%+ memory alerts on TrueNAS
and FreeBSD hosts. Build-tagged so it compiles cleanly on all platforms.

Previously, when some cluster endpoints were unreachable (e.g., backup
nodes intentionally offline), the cluster was marked as "degraded" even
though the Proxmox cluster itself was healthy and had quorum.
Now the connection health check queries the Proxmox cluster's actual
quorum status. A cluster is only marked "degraded" if it has lost
quorum (not enough votes for consensus), which is the actual indicator
of cluster instability.
This means:
- Cluster with quorum + some nodes offline = "healthy"
- Cluster without quorum = "degraded" (warning)
- All endpoints down = "error"
Fixes#1085
When discovering cluster nodes, Pulse now automatically prefers IPs
on the same subnet as the initial connection. This fixes the common
issue where Pulse used internal cluster network IPs (e.g., 172.x.x.x)
instead of management network IPs (e.g., 10.x.x.x).
How it works:
1. Extract subnet from initial connection URL (assumes /24 for IPv4)
2. For each discovered node, query /nodes/{node}/network for all IPs
3. If cluster-reported IP is on a different subnet, find an IP on
the preferred subnet and set it as IPOverride
4. Manual IPOverride settings are preserved and take precedence
This eliminates the need for manual IPOverride configuration in most
multi-network Proxmox setups.

Changes:
1. Add MAX_POLL_TIMEOUT env var for large Proxmox clusters that need
more than 3 minutes for polling (default: 3m, minimum: 30s)
2. Handle external Ceph storage gracefully - don't mark nodes unhealthy
when Proxmox returns 'binary not installed' (e.g., for Ceph not
managed by Proxmox)

- Add comprehensive debug logging to diagnose replication status fetch failures
- Handle both array and single-object response formats from Proxmox API
- Log raw response body for easier debugging
- Log success/failure for each enrichment step
This helps diagnose issue #992 where replication last/next sync times aren't
showing. The logging will reveal if the API call is failing, returning empty
data, or returning data in an unexpected format.

Ensures that LinkedHostAgentId, CommandsEnabled, IsLegacy, and LinkedNodeId
are correctly propagated to the frontend. This prevents regressions of the
bugs fixed for #952 and #971.
- Add persistent volume mounts for Go/npm caches (faster rebuilds)

The /cluster/replication endpoint only returns job configuration (guest,
schedule, source, target), not status data (last_sync, next_sync,
duration, fail_count, state).
This fix enriches each replication job with status from the per-node
endpoint /nodes/{node}/replication/{id}/status to get timing and state
data needed for proper UI display.
Added integration tests to verify:
- Status endpoint is called and data is merged correctly
- Graceful handling when status endpoint fails
Fixes#992
PBS storage content queries with encrypted backups can take 10-20+ seconds
to enumerate. The previous 30s timeout was causing intermittent failures
when polling backup data from PBS storage configured in PVE.
This increases the timeout to 60s to accommodate slow PBS backends while
still preventing indefinite hangs on unavailable NFS/network storage.
When a PVE cluster has unique self-signed certificates on each node, Pulse
would mark secondary nodes as unhealthy because only the primary node's
fingerprint was used for all connections.
Now, during cluster discovery, Pulse captures each node's TLS fingerprint
and uses it when connecting to that specific node. This enables
"Trust On First Use" (TOFU) for clusters with unique per-node certs.
Changes:
- Add Fingerprint field to ClusterEndpoint config
- Add FetchFingerprint() to tlsutil for capturing node certs
- validateNodeAPI() now captures and returns fingerprints during discovery
- NewClusterClient() accepts endpointFingerprints map for per-node certs
- All client creation paths use per-endpoint fingerprints when available
Related to #879
- Add sanitizeEndpointError() to transform raw Go errors into user-friendly messages
- Transform 'context deadline exceeded' into helpful messages mentioning possible causes
- Storage timeout errors now suggest checking PBS/NFS/Ceph backend connectivity
- Connection refused, certificate errors, and auth errors get actionable hints
- Apply sanitization everywhere cluster endpoint lastError is stored
- Add comprehensive tests for all error transformations
- Add 'content' type to StreamDisplayEvent for tracking text chunks
- Track content events in streamEvents array for chronological display
- Update render to use Switch/Match for cleaner conditional rendering
- Interleave thinking, tool calls, and content as they stream in
- Add fallback for old messages without streamEvents for backwards compat
Previously, tool/command outputs stayed at top while AI text responses
accumulated at the bottom. Now all events appear in order like a
normal chatbot.

Coverage improved from 95.8% to 100%.
The error pattern `/storage/` only matched storage content endpoints
(`/storage/{name}/content`) but not the main storage list endpoint
(`/nodes/{node}/storage`).
This caused storage timeout errors like:
Get ".../nodes/pve-100-224/storage": context deadline exceeded
to incorrectly mark cluster nodes as unhealthy, even though the timeout
was due to a slow cross-node storage query, not actual node connectivity
issues.
Fixes#754
