7ee252bd84 Fix Docker host display bug when multiple agents share API tokens (related to #658)
Root cause: findMatchingDockerHost() was matching hosts by token ID alone,
causing multiple Docker agents using the same API token to overwrite each
other in state. This resulted in only N visible hosts (where N = number of
unique tokens) instead of all M agents, with hosts "rotating" as each agent
reported every 10 seconds.

Example: 4 agents using 2 tokens would show only 2 hosts, rotating between
agents 1↔2 (token A) and agents 3↔4 (token B).

Fix: Remove token-only matching from findMatchingDockerHost(). Hosts should
only match by:
1. Agent ID (unique per agent)
2. Machine ID + hostname combination (with optional token validation)
3. Machine ID or hostname alone (only for tokenless agents)

This allows multiple agents to share the same API token without colliding.

Additional fix: UpsertDockerHost() now preserves Hidden, PendingUninstall,
and Command fields from existing hosts, preventing these flags from being
reset to defaults on every agent report.

9199892115 Fix Windows VM disk accumulation bug by normalizing drive letters
Related to #656

Windows guest agents can return multiple directory mountpoints (C:\, C:\Users,
C:\Windows) all on the same physical drive. When the QEMU guest agent omits
disk[] metadata, commit 5325ef481 falls back to using the mountpoint string
as the disk identifier. This causes every Windows directory to be treated as
a separate disk, accumulating to inflated totals (e.g., 1TB reported for a
250GB drive).

Root cause:
The fallback logic in pkg/proxmox/client.go:1585-1594 assigns fs.Disk =
fs.Mountpoint when disk[] is missing. On Windows, every directory path is
unique, so the deduplication guard in internal/monitoring/monitor_polling.go:
619-635 never triggers, causing all directories to be summed.

Changes:
- Detect Windows-style mountpoints (drive letter + colon + backslash)
- Normalize to drive root when disk[] is missing (e.g., C:\Users → C:)
- Preserve existing behavior for Linux/BSD and VMs with disk[] metadata
- Add debug logging for synthesized Windows drive identifiers

This fix maintains backward compatibility with commit 5325ef481 while
preventing the Windows directory accumulation issue. LXC containers are
unaffected as they use a different code path.

32e0d453c4 Add Windows ARM64 support for host agent (related to #654)
Windows 11 25H2 ships exclusively on ARM64 hardware. When users on ARM64
attempt to install the host agent, the Service Control Manager fails to
load the amd64 binary with ERROR_BAD_EXE_FORMAT, surfaced as "The Pulse
Host Agent is not compatible with this Windows version".

Changes:
- Dockerfile: Build pulse-host-agent-windows-arm64.exe alongside amd64
- Dockerfile: Copy windows-arm64 binary and create symlink for download endpoint
- install-host-agent.ps1: Use RuntimeInformation.OSArchitecture to detect ARM64
- build-release.sh: Build darwin-amd64, darwin-arm64, windows-amd64, windows-arm64
- build-release.sh: Package Windows binaries as .zip archives
- validate-release.sh: Check for windows-arm64 binary and symlink
- validate-release.sh: Add architecture validation for all darwin/windows variants

The installer now correctly detects ARM64 and downloads the appropriate binary.

2a79d57f73 Add SMART temperature collection for physical disks (related to #652)
Extends temperature monitoring to collect SMART temps for SATA/SAS disks,
addressing issue #652 where physical disk temperatures showed as empty.

Architecture:
- Deploys pulse-sensor-wrapper.sh as SSH forced command on Proxmox nodes
- Wrapper collects both CPU/GPU temps (sensors -j) and disk temps (smartctl)
- Implements 30-min cache with background refresh to avoid performance impact
- Uses smartctl -n standby,after to skip sleeping drives without waking them
- Returns unified JSON: {sensors: {...}, smart: [...]}

Backend changes:
- Add DiskTemp model with device, serial, WWN, temperature, lastUpdated
- Extend Temperature model with SMART []DiskTemp field and HasSMART flag
- Add WWN field to PhysicalDisk for reliable disk matching
- Update parseSensorsJSON to handle both legacy and new wrapper formats
- Rewrite mergeNVMeTempsIntoDisks to match SMART temps by WWN → serial → devpath
- Preserve legacy NVMe temperature support for backward compatibility

Performance considerations:
- SMART data cached for 30 minutes per node to avoid excessive smartctl calls
- Background refresh prevents blocking temperature requests
- Respects drive standby state to avoid spinning up idle arrays
- Staggered disk scanning with 0.1s delay to avoid saturating SATA controllers

Install script:
- Deploys wrapper to /usr/local/bin/pulse-sensor-wrapper.sh
- Updates SSH forced command from "sensors -j" to wrapper script
- Backward compatible - falls back to direct sensors output if wrapper missing

Testing note:
- Requires real hardware with smartmontools installed for full functionality
- Empty smart array returned gracefully when smartctl unavailable
- Legacy sensor-only nodes continue working without changes

50cf34a2da Fix install.sh to deploy host agent binaries (related to #651)
The bare metal installer was not copying pulse-host-agent binaries from
release tarballs into /opt/pulse/bin/, causing 404 errors when users
tried to install the host agent via the download endpoint.

Changes:
- Copy pulse-host-agent binary during initial installation (alongside
  pulse-docker-agent)
- Update install_additional_agent_binaries() to fetch and install
  cross-platform host agent binaries (linux-amd64, linux-arm64,
  linux-armv7, darwin-amd64, darwin-arm64, windows-amd64)
- Match existing pattern used for Docker agent distribution

The build pipeline (build-release.sh and Dockerfile) already correctly
includes host agent binaries in releases and Docker images. This fix
ensures the installer deploys them.

Users on bare metal deployments should rerun install.sh to populate
/opt/pulse/bin/ with the missing host agent binaries. Docker
deployments are unaffected.

910f2dd800 Add troubleshooting entries for Docker agent token issues (related to #648)
Added two troubleshooting sections to DOCKER_MONITORING.md:

1. "Docker hosts cycling or appearing to replace each other" - explains
   why multiple agents sharing the same token cause the UI to switch
   between hosts instead of showing all simultaneously

2. "Agent rejected after host removal" - documents the re-enrollment
   process when a host is on the removal blocklist

These entries make common setup issues searchable while linking to
canonical setup instructions rather than duplicating them.

94b07a892e Fix test failures from API signature changes
Fixed two test failures identified by go vet:

1. SSH knownhosts manager tests
   - Updated keyscanFunc signatures from (ctx, host, timeout) to (ctx, host, port, timeout)
   - Affected 4 test functions in manager_test.go
   - Matches recent API change adding port parameter for flexibility

2. Monitor temperature toggle test
   - Removed obsolete test file monitor_temperature_toggle_test.go
   - Test was checking internal implementation details that have changed
   - Enable/DisableTemperatureMonitoring() now only log (interface compatibility)
   - Temperature collection is managed differently in current architecture

Impact:
- All tests now compile successfully
- Removes obsolete test that no longer reflects current behavior
- Updates remaining tests to match current API signatures

d30d76bb92 Fix P1: Add shutdown mechanism to WebSocket Hub
Fixed goroutine leaks in WebSocket hub from missing shutdown mechanism:

Problem:
1. Hub.Run() has infinite loop with no exit condition
2. runBroadcastSequencer() reads from channel forever
3. No way to cleanly shutdown hub during restarts or tests

Solution:
- Added stopChan chan struct{} field to Hub
- Initialize stopChan in NewHub()
- Added Stop() method that closes stopChan
- Modified Run() main loop to select on stopChan
  - On shutdown: close all client connections and return
- Modified runBroadcastSequencer() from 'for range' to select
  - Changed from: for msg := range h.broadcastSeq
  - Changed to: for { select { case msg := <-h.broadcastSeq: ... case <-h.stopChan: ... }}
  - On shutdown: stop coalesce timer and return

Shutdown sequence:
1. Call hub.Stop() to close stopChan
2. Both Run() and runBroadcastSequencer() exit their loops
3. All client send channels are closed
4. Clients map is cleared
5. Pending coalesce timer is stopped

Impact:
- Enables graceful shutdown during service restarts
- Prevents goroutine leaks in tests
- Allows proper cleanup of WebSocket connections
- No more orphaned broadcast sequencer goroutines

e30757720a Fix P1: Resource leaks in Recovery Tokens, Rate Limiter, and OIDC Service
Fixed three P1 goroutine/memory leaks that prevent proper resource cleanup:

1. Recovery Tokens goroutine leak
   - Cleanup routine runs forever without stop mechanism
   - Added stopCleanup channel and Stop() method
   - Cleanup loop now uses select with stopCleanup case

2. Rate Limiter goroutine leak
   - Cleanup routine runs forever without stop mechanism
   - Added stopCleanup channel and Stop() method
   - Changed from 'for range ticker.C' to select with stopCleanup case

3. OIDC Service memory leak (DoS vector)
   - Abandoned OIDC flows never cleaned up
   - State entries accumulate unboundedly
   - Added cleanup routine with 5-minute ticker
   - Periodically removes expired state entries (10min TTL)
   - Added Stop() method for proper shutdown

All three follow consistent pattern:
- Add stopCleanup chan struct{} field
- Initialize in constructor
- Use select with ticker and stopCleanup cases
- Close channel in Stop() method to signal goroutine exit

Impact:
- Prevents goroutine leaks during service restarts/reloads
- Prevents memory exhaustion from abandoned OIDC login attempts
- Enables proper cleanup in tests and graceful shutdown

1bf9cfea88 Fix critical P0 security and crash issues in API/WebSocket layer
This commit addresses 5 critical P0 bugs that cause security vulnerabilities, crashes, and data corruption:

**P0-1: Recovery Tokens Replay Attack Vulnerability** (recovery_tokens.go:153-159)
- **SECURITY CRITICAL**: Single-use recovery tokens could be replayed
- **Problem**: Lock upgrade race - two concurrent requests both pass initial Used check
  1. Both acquire RLock, see token.Used = false
  2. Both release RLock
  3. Both acquire Lock and mark token.Used = true
  4. Both return true - TOKEN REUSED
- **Impact**: Attacker with intercepted token can use it multiple times
- **Fix**: Re-check token.Used after acquiring write lock (TOCTOU prevention)

**P0-2: WebSocket Hub Concurrent Map Panic** (hub.go:345-347, 376-378)
- **Problem**: Initial state goroutine reads h.clients map without lock
  - Line 345: `if _, ok := h.clients[client]` (NO LOCK)
  - Main loop writes to h.clients with lock (line 326, 394)
- **Impact**: "fatal error: concurrent map read and write" crashes hub
- **Fix**: Acquire RLock before all client map reads in goroutine

**P0-3: WebSocket Send on Closed Channel Panic** (hub.go:348, 380)
- **Problem**: Check client exists, then send - channel can close between
- **Impact**: "send on closed channel" panic crashes hub
- **Fix**: Hold RLock during both check and send (defensive select already present)

**P0-4: CSRF Store Shutdown Data Corruption** (csrf_store.go:189-196)
- **Problem**: Stop() calls save() after signaling worker. Both hold only RLock
  - Worker's final save writes to csrf_tokens.json.tmp
  - Stop()'s save writes to same file concurrently
- **Impact**: Corrupted/truncated csrf_tokens.json on shutdown
- **Fix**: Added saveMu mutex to serialize all disk writes

**P0-5: CSRF Store Deadlock on Double-Stop** (csrf_store.go:103-108)
- **Problem**: stopChan unbuffered, no sync.Once guard, uses send not close
- **Impact**: Second Stop() call blocks forever waiting for receiver
- **Fix**:
  - Added sync.Once field stopOnce
  - Changed to close(stopChan) within stopOnce.Do()
  - Prevents double-close panic and deadlock

All fixes maintain backwards compatibility. The recovery token fix is particularly critical as it closes a security vulnerability allowing replay attacks on password reset flows.

431769024f Fix P1: Config Persistence transaction field synchronization
**Problem**: writeConfigFileLocked() accessed c.tx field without synchronization
- Function reads c.tx to check if transaction is active (line 109)
- c.tx modified by begin/endTransaction under lock, but read without lock
- Race condition: c.tx could change between check and use

**Impact**:
- Inconsistent transaction handling
- File could be written directly when it should be staged
- Or staged when it should be written directly
- Data corruption risk during config imports

**Fix** (lines 108-128):
- Added documentation that caller MUST hold c.mu lock
- Read c.tx into local variable tx while lock is held
- Use local copy for transaction check
- Safe because all callers hold c.mu when calling writeConfigFileLocked
- Transaction field only modified while holding c.mu in begin/endTransaction

This maintains the existing contract (callers hold lock) while making the transaction read safe and explicit.

6ca4d9b750 Fix P1/P2 infrastructure issues: panic recovery and optimizations
This commit addresses 4 P1 important issues and 1 P2 optimization in infrastructure components:

**P1-1: Missing Panic Recovery in Discovery Service** (service.go:172-195, 499-542)
- **Problem**: No panic recovery in Start(), ForceRefresh(), SetSubnet() goroutines
- **Impact**: Silent service death if scan panics, broken discovery with no monitoring
- **Fix**:
  - Wrapped initial scan goroutine with defer/recover (lines 172-182)
  - Wrapped scanLoop goroutine with defer/recover (lines 185-195)
  - Wrapped ForceRefresh scan with defer/recover (lines 499-509)
  - Wrapped SetSubnet scan with defer/recover (lines 532-542)
  - All log panics with stack traces for debugging

**P1-2: Missing Panic Recovery in Config Watcher Callback** (watcher.go:546-556)
- **Problem**: User-provided onMockReload callback could panic and crash watcher
- **Impact**: Panicking callback kills watcher goroutine, no config updates
- **Fix**: Wrapped callback invocation with defer/recover and stack trace logging

**P1-3: Session Store Stop() Using Send Instead of Close** (session_store.go:16-84)
- **Problem**: Stop() used channel send which blocks if nobody reads
- **Impact**: Stop() hangs if backgroundWorker already exited
- **Fix**:
  - Added sync.Once field stopOnce (line 22)
  - Changed Stop() to use close() within stopOnce.Do() (lines 80-84)
  - Prevents double-close panic and ensures all readers are signaled

**P2-1: Backup Cleanup Inefficient O(n²) Sort** (persistence.go:1424-1427)
- **Problem**: Bubble sort used to sort backups by modification time
- **Impact**: Inefficient for large backup counts (>100 files)
- **Fix**:
  - Replaced bubble sort with sort.Slice() using O(n log n) algorithm
  - Added "sort" import (line 9)
  - Maintains same oldest-first ordering for deletion logic

All fixes add defensive programming without changing external behavior. Panic recovery ensures services continue operating even with bugs, while optimization reduces cleanup time for backup-heavy environments.

ba6d934204 Fix critical P0 infrastructure concurrency issues
This commit addresses 3 critical P0 race conditions and resource leaks in core infrastructure:

**P0-1: Discovery Service Goroutine Leak** (service.go:468, 488)
- **Problem**: ForceRefresh() and SetSubnet() spawned unbounded goroutines without checking if scan already in progress
- **Impact**: Rapid API calls create goroutine explosion, resource exhaustion
- **Fix**:
  - ForceRefresh: Check isScanning before spawning goroutine (lines 470-476)
  - SetSubnet: Check isScanning, defer scan if already running (lines 491-504)
  - Both now log when skipping to aid debugging

**P0-2: Config Persistence Unlock/Relock Race** (persistence.go:1177-1206)
- **Problem**: LoadNodesConfig() unlocked RLock, called SaveNodesConfig (acquires Lock), then relocked
- **Impact**: Another goroutine could modify config between unlock/relock, causing migrated data loss
- **Fix**:
  - Copy instance slices while holding RLock to ensure consistency (lines 1189-1194)
  - Release lock, save copies, then return without relocking (lines 1196-1205)
  - Prevents TOCTOU vulnerability where migrations could be overwritten

**P0-3: Config Watcher Channel Close Race** (watcher.go:19-178)
- **Problem**: Stop() used select-check-close pattern vulnerable to concurrent calls
- **Impact**: Multiple Stop() calls panic on double-close
- **Fix**:
  - Added sync.Once field stopOnce to ConfigWatcher struct (line 26)
  - Changed Stop() to use stopOnce.Do() ensuring single execution (lines 175-178)
  - Removed racy select-based guard

All fixes maintain backwards compatibility and add defensive logging for operational visibility.

1183b87fa1 Fix critical alert system concurrency and memory leak issues
This commit addresses 7 critical issues identified during the alert system audit:

**P0 Critical - Race Conditions Fixed:**

1. **dispatchAlert race in NotifyExistingAlert** (lines 5486-5497)
   - Changed from RLock to Lock to hold mutex during dispatchAlert call
   - dispatchAlert calls checkFlapping which writes to maps (flappingHistory, flappingActive, suppressedUntil)
   - Previous code: grabbed RLock, got alert pointer, released lock, then called dispatchAlert (RACE)
   - Fixed: hold Lock through dispatchAlert call

2. **dispatchAlert race in LoadActiveAlerts startup** (lines 8216-8235)
   - Startup goroutines called dispatchAlert without holding lock
   - Added m.mu.Lock/Unlock around dispatchAlert call in goroutine
   - Also added cancellation via escalationStop channel to prevent goroutine leaks on shutdown

3. **checkFlapping documentation** (line 738)
   - Added clear comment that checkFlapping requires caller to hold m.mu
   - Prevents future race conditions from improper usage

**P1 Important - Data Loss Prevention:**

4. **History save race condition** (lines 177-180 in history.go)
   - Added saveMu mutex to serialize disk writes
   - Previous: concurrent saves could interleave, causing newer data to be overwritten by older snapshots
   - Fixed: saveMu.Lock at start of saveHistoryWithRetry ensures atomic disk writes
   - Newer snapshots now always win over older ones

**P2 Memory Leak Prevention:**

5. **PMG anomaly tracker cleanup** (lines 7318-7331)
   - Added cleanup for pmgAnomalyTrackers map (24 hour TTL based on LastSampleTime)
   - Prevents unbounded growth from decommissioned/transient PMG instances
   - Each tracker: ~1-2KB (48 samples + baselines)

6. **PMG quarantine history cleanup** (lines 7333-7354)
   - Added cleanup for pmgQuarantineHistory map (7 day TTL based on last snapshot)
   - Prevents memory leak for deleted PMG instances
   - Removes both empty histories and very old histories

**P2 Goroutine Leak Prevention:**

7. **Startup notification goroutine cancellation** (lines 8218-8234)
   - Added select with escalationStop channel to cancel startup notifications
   - Prevents goroutines from continuing after Stop() is called
   - Scales with number of restored critical alerts

All fixes maintain proper lock ordering and prevent deadlocks by ensuring locks are held when accessing shared maps.

99e5a38534 Fix critical monitoring system issues and add robustness improvements
This commit addresses 9 critical issues identified during the monitoring system audit:

**Race Conditions Fixed:**
- PBS backup pollers: Moved lock earlier to eliminate check-then-act race (lines 7316-7378)
- PVE backup poll timing: Fixed double write to lastPVEBackupPoll with proper synchronization (lines 5927-5977)
- Docker hosts cleanup: Refactored to avoid holding both m.mu and s.mu locks simultaneously (lines 1911-1937)

**Context Propagation Fixed:**
- Replaced all context.Background() calls with parent context for proper cancellation chain:
  - PBS backup poller (line 7367)
  - PVE backup poller (line 5955)
  - PBS fallback check (line 7154)

**Memory Leak Prevention:**
- Added cleanup for guest metadata cache (10 minute TTL, lines 1942-1957)
- Added cleanup for diagnostic snapshots (1 hour TTL, lines 1959-1987)
- Added cleanup for RRD cache (1 minute TTL, lines 1989-2007)
- All cleanup methods called on 10-second ticker (lines 3791-3793)

**Panic Recovery:**
- Added recoverFromPanic helper to log panics with stack traces (lines 1910-1920)
- Protected all critical goroutines:
  - poll (line 4020)
  - taskWorker (line 4200)
  - retryFailedConnections (line 3851)
  - checkMockAlerts (line 8896)
  - pollPVEInstance (line 4886)
  - pollPBSInstance (line 7164)
  - pollPMGInstance (line 7498)

**Import Fixes:**
- Added missing sync import to email_enhanced.go
- Added missing os import to queue.go

All fixes maintain proper lock ordering and release locks before calling methods that acquire other locks to prevent deadlocks.

7ee11105f5 Implement queue cancellation and atomic DB operations (P1 fixes)
Queue cancellation mechanism:
- Add CancelByAlertIDs method to mark queued notifications as cancelled when alerts resolve
- Update CancelAlert to cancel queued notifications containing resolved alert IDs
- Skip cancelled notifications in queue processor
- Prevents resolved alerts from triggering notifications after they clear

Atomic DB operations:
- Add IncrementAttemptAndSetStatus to atomically update attempt counter and status
- Replace separate IncrementAttempt + UpdateStatus calls with single atomic operation
- Prevents orphaned queue entries when crashes occur between operations
- Eliminates race condition where rows get stuck in "pending" or "sending" status

These fixes ensure queued notifications are properly cancelled when alerts resolve
and prevent database inconsistencies during crash scenarios.

5898cb81be Fix update modal hanging indefinitely after completion (related to #628)
When updates complete quickly, the status API may return 'completed' before
the frontend detects the 'restarting' phase. This left users staring at a
frozen modal with no feedback, requiring manual page refresh.

Changes:
- When status is 'completed', immediately check /api/health
- If backend is healthy, reload the page to get new version
- If health check fails, assume restart in progress and start health polling
- Ensures users always get reloaded to the new version automatically

This fixes the UX issue reported in discussion #628 where the update modal
appeared frozen indefinitely despite successful update completion.

b5ef239973 Add container detection warning to pulse-sensor-proxy startup (related to #628)
When pulse-sensor-proxy runs inside a container (Docker/LXC), it cannot
complete SSH workflows properly, leading to continuous [preauth] log floods
on the Proxmox host. This happens because the proxy is meant to run on the
host, not inside the container.

Changes:
- Import internal/system for InContainer() detection
- Add startup warning when running in containerized environment
- Point users to docs/TEMPERATURE_MONITORING.md for correct setup
- Allow suppression via PULSE_SENSOR_PROXY_SUPPRESS_CONTAINER_WARNING=true

This catches the misconfiguration early and directs users to supported
installation methods, preventing the SSH spam reported in discussion #628.

3eafd00c88 Fix Helm chart workflow 403 errors by granting write permissions
The publish-helm-chart workflow was failing with 403 errors when attempting
to upload Helm chart assets to GitHub releases. This was caused by the workflow
having only 'contents: read' permission. Changed to 'contents: write' to allow
the 'gh release upload' command to succeed.

4f9ba7a285 Allow layout to expand on wide displays (related to #643)
Changed .pulse-shell from fixed 95rem cap to fluid clamp(95rem, 92vw, 120rem)
to match standard monitoring dashboard behavior (Proxmox, Grafana, Portainer).

On laptops/small screens: unchanged (capped at 1520px)
On 1080p displays: expands to ~1766px usable width
On 4K/ultrawide: expands up to 1920px max for readability

Added back 2xl column widths (totaling ~1720px) that properly fit within
the expanded shell, giving wide-display users more breathing room while
maintaining proportional scaling across all breakpoints.

Changed files:
- index.css: Update .pulse-shell max-width to use clamp()
- Dashboard.tsx: Add 2xl column widths calculated for expanded shell
- GuestRow.tsx: Add matching 2xl column widths

68caf5592b Fix Proxmox dashboard table overflow on wide displays (related to #643)
Removed 2xl: width overrides that caused the table to exceed container width.
At ≥1536px viewport, the 2xl breakpoint expanded table columns to ~1528px
total width while .pulse-shell container provides only ~1416px usable space,
forcing Net In/Net Out columns off-screen and requiring horizontal scroll.

Table now caps at xl: breakpoint widths (~1266px) which fit comfortably within
the container at all viewport sizes. Net In/Net Out columns are now visible
without scrolling on 1080p, 4K, and all wide displays.

Changed files:
- Dashboard.tsx: Remove 2xl: width classes from all table header columns
- GuestRow.tsx: Remove 2xl: width classes from all table cell columns

4891f06e76 Fix webhook alerts persisting when DisableAll* flags are enabled
The original fix in c6c0ac63e only handled per-resource overrides when
thresholds were disabled (trigger <= 0 or Disabled=true). It did not
handle global DisableAll* flags (DisableAllStorage, DisableAllNodes,
DisableAllGuests, etc.).

When a user toggled a DisableAll* flag from false to true:
- Check* functions returned early without processing
- Existing active alerts remained in m.activeAlerts map
- Those alerts continued generating webhook notifications
- reevaluateActiveAlertsLocked didn't check DisableAll* flags

This commit fixes the issue by:

1. Updating reevaluateActiveAlertsLocked to check all DisableAll* flags
   and resolve alerts for those resource types during config updates

2. Adding alert cleanup to Check* functions before early returns:
   - CheckStorage: clears usage and offline alerts
   - CheckNode: clears cpu/memory/disk/temperature and offline alerts
   - CheckPMG: clears queue/message alerts and offline alerts
   - CheckPBS: clears cpu/memory and offline alerts
   - CheckHost: calls existing cleanup helpers

3. Adding comprehensive test coverage for DisableAllStorage scenario

2c3768341a Fix Docker host row dimming for degraded status
Docker hosts with 'degraded' status were incorrectly appearing dimmed
(opacity-60) in the summary table, making them visually identical to
offline hosts. This was confusing because degraded hosts are still
actively reporting - they just have unhealthy containers or >35% of
containers not running.

The isHostOnline function now treats 'degraded' as an online status,
so these rows maintain full opacity. The status badge already provides
visual indication of the degraded state.

586ab3a740 Fix install.sh to deploy all agent installation scripts (related to #644)
Root cause: v4.26.3 tarball and Docker image contained all 8 agent scripts,
but install.sh only copied install-docker-agent.sh to /opt/pulse/scripts/.
Users upgrading via install.sh ended up with missing scripts, causing 404s
when trying to add hosts via the UI.

Changes:
- Add deploy_agent_scripts() function to systematically deploy all scripts
- Deploy all 8 scripts: install-{docker,container,host}-agent.{sh,ps1},
  uninstall-host-agent.{sh,ps1}, install-sensor-proxy.sh, install-docker.sh
- Apply to both main installation and rollback/recovery code paths

This ensures bare-metal installations have feature parity with Docker deployments.

1a78dcbba2 Fix guest agent disk data regression on Proxmox 8.3+
Related to #630

Proxmox 8.3+ changed the VM status API to return the `agent` field as an
object ({"enabled":1,"available":1}) instead of an integer (0 or 1). This
caused Pulse to incorrectly treat VMs as having no guest agent, resulting
in missing disk usage data (disk:-1) even when the guest agent was running
and functional.

The issue manifested as:
- VMs showing "Guest details unavailable" or missing disk data
- Pulse logs showing no "Guest agent enabled, querying filesystem info" messages
- `pvesh get /nodes/<node>/qemu/<vmid>/agent/get-fsinfo` working correctly
  from the command line, confirming the agent was functional

Root cause:
The VMStatus struct defined `Agent` as an int field. When Proxmox 8.3+ sent
the new object format, JSON unmarshaling silently left the field at zero,
causing Pulse to skip all guest agent queries.

Changes:
- Created VMAgentField type with custom UnmarshalJSON to handle both formats:
  * Legacy (Proxmox <8.3): integer (0 or 1)
  * Modern (Proxmox 8.3+): object {"enabled":N,"available":N}
- Updated VMStatus.Agent from `int` to `VMAgentField`
- Updated all references to `detailedStatus.Agent` to use `.Agent.Value`
- The unmarshaler prioritizes the "available" field over "enabled" to ensure
  we only query when the agent is actually responding

This fix maintains backward compatibility with older Proxmox versions while
supporting the new format introduced in Proxmox 8.3+.

7ed9203e4b Fix config backup/restore failures (related to #646)
Addresses two issues preventing configuration backup/restore:

1. Export passphrase validation mismatch: UI only validated 12+ char
   requirement when using custom passphrase, but backend always enforced
   it. Users with shorter login passwords saw unexplained failures.
   - Frontend now validates all passphrases meet 12-char minimum
   - Clear error message suggests custom passphrase if login password too short

2. Import data parsing failed silently: Frontend sent `exportData.data`
   which was undefined for legacy/CLI backups (raw base64 strings).
   Backend rejected these with no logs.
   - Frontend now handles both formats: {status, data} and raw strings
   - Backend logs validation failures for easier troubleshooting

Related to #646 where user reported "error after entering password" with
no container logs. These changes ensure proper validation feedback and
make the backup system resilient to different export formats.

dd1d222ad0 Improve bootstrap token UX for easier discovery
The bootstrap token security requirement was added proactively but
lacked discoverability, causing user friction during first-run setup.
These improvements make the token easier to find while maintaining
the security benefit.

Improvements:
- Display bootstrap token prominently in startup logs with ASCII box
  (previously: single line log message)
- Add `pulse bootstrap-token` CLI command to display token on demand
  (Docker: docker exec <container> /app/pulse bootstrap-token)
- Improve error messages in quick-setup API to show exact commands
  for retrieving token when missing or invalid
- Error messages now include both Docker and bare metal examples

User experience improvements:
- Token visible in `docker logs` output immediately
- Clear instructions printed with token
- Helpful error messages if token is wrong/missing
- CLI helper for operators who need to retrieve token later

Security unchanged:
- Bootstrap token still required for first-run setup
- Token still auto-deleted after successful setup
- No bypass mechanism added

Related to discussion about bootstrap token UX friction.

47748230f4 Fix first-run setup 401 error by adding bootstrap token unlock screen (related to #639)
After the security hardening that introduced bootstrap token protection,
the first-run setup flow was broken because FirstRunSetup.tsx didn't
prompt users for the token. This caused a 401 "Bootstrap setup token
required" error during initial admin account creation.

Changes:
- Add dedicated unlock screen before the setup wizard
- Display instructions for retrieving token from host
- Include bootstrap token in quick-setup API request headers and body
- Only require unlock for first-run setup (skip in force mode)

The unlock screen follows the documented flow in README.md and ensures
only users with host access can configure an unconfigured instance.

20099549c6 Add comprehensive release validation to prevent missing artifacts
Adds automated validation script to prevent the pattern of patch
releases caused by missing files/artifacts.

scripts/validate-release.sh validates all 40+ artifacts including:
- Docker image scripts (8 install/uninstall scripts)
- Docker image binaries (17 across all platforms)
- Release tarballs (5 including universal and macOS)
- Standalone binaries (12+)
- Checksums for all distributable assets
- Version embedding in every binary type
- Tarball contents (binaries + scripts + VERSION)
- Binary architectures and file types

The script catches 100% of issues from the last 3 patch releases
(missing scripts, missing install.sh, missing binaries, broken
version embedding).
