Setup script improvements (config_handlers.go):
- Remove redundant mount configuration and container restart logic
- Let installer handle all mount/restart operations (single source of truth)
- Eliminate hard-coded mp0 assumption
Installer improvements (install-sensor-proxy.sh):
- Add mount configuration persistence validation via pct config check
- Surface pct set errors instead of silencing with 2>/dev/null
- Capture and display curl download errors with temp files
- Check systemd daemon-reload/enable/restart exit codes
- Show journalctl output when service fails to start
- Make socket verification fatal (was warning)
- Provide clear manual steps when hot-plug fails on running container
This makes the installation fail fast with actionable error messages
instead of silently proceeding with broken configuration.
Changes:
- Replace PULSE_SENSOR_PROXY_FALLBACK_URL env export with --pulse-server argument
- Remove --quiet flag from installer invocation to show download progress
- More reliable than environment variable inheritance in subshells
This ensures the proxy installer can reliably download the binary from the
Pulse server fallback when GitHub is unavailable.
The setup script was filtering installer output to only show lines with
✓|⚠️|ERROR, which hid successful download messages like:
'Downloading pulse-sensor-proxy-linux-amd64 from Pulse server...'
This made it appear the installer failed even when the Pulse server
fallback download succeeded. Changed to show all installer output for
better visibility and debugging.
Users will now see the complete installation flow including:
- GitHub download attempt (expected to fail for dev builds)
- Pulse server fallback download (should succeed)
- All setup steps and validations
Improves transparency and reduces confusion during setup
Version check was blocking dev/main builds (e.g., '0.0.0-main-da9da6f')
from using temperature proxy, even though they have the latest code.
Added regex to skip version check for builds matching:
- ^0\.0\.0-main (main branch builds)
- ^dev (dev builds)
- ^main (main version strings)
These builds are assumed to have proxy support since they're built from
the latest codebase.
Fixes testing workflow when installing Pulse with --main flag
The version check was blocking ALL v4.23.0 users from temperature monitoring,
even non-containerized ones who don't need the proxy.
Changed to only check version when PULSE_IS_CONTAINERIZED=true, since:
- Non-containerized Pulse can use direct SSH on any version
- Containerized Pulse requires v4.24.0+ for proxy support
This ensures non-containerized v4.23.0 users can still use temperature monitoring
via direct SSH while properly blocking proxy setup for containerized v4.23.0.
Fixes regression introduced in commit fbe4ab83a
Improves configuration handling and system settings APIs to support
v4.24.0 features including runtime logging controls, adaptive polling
configuration, and enhanced config export/persistence.
Changes:
- Add config override system for discovery service
- Enhance system settings API with runtime logging controls
- Improve config persistence and export functionality
- Update security setup handling
- Refine monitoring and discovery service integration
These changes provide the backend support for the configuration
features documented in the v4.24.0 release.
Resolves two remaining TODOs from codebase audit.
## 1. PBS/PMG Test Harness Stubs
**Location:** internal/monitoring/harness_integration.go:149-151
**Changes:**
- Added PBS client stub registration: `monitor.pbsClients[inst.Name] = &pbs.Client{}`
- Added PMG client stub registration: `monitor.pmgClients[inst.Name] = &pmg.Client{}`
- Added imports for pkg/pbs and pkg/pmg
**Purpose:**
Enables integration test scenarios to include PBS and PMG instance types
alongside existing PVE support. Stubs allow scheduler to register and
execute tasks for these instance types during integration testing.
**Testing:**
✅ TestAdaptiveSchedulerIntegration passes (55.5s)
✅ Integration test harness now supports all three instance types
## 2. HTTP Config URL Fetch
**Location:** cmd/pulse/config.go:226-261
**Problem:**
`PULSE_INIT_CONFIG_URL` was recognized but not implemented, returning
"URL import not yet implemented" error.
**Implementation:**
- URL validation (http/https schemes only)
- HTTP client with 15 second timeout
- Status code validation (2xx required)
- Empty response detection
- Base64 decoding with fallback to raw data
- Matches existing env-var behavior for `PULSE_INIT_CONFIG_DATA`
**Security:**
- Both HTTP and HTTPS supported (HTTPS recommended for production)
- URL scheme validation prevents file:// or other protocols
- Timeout prevents hanging on unresponsive servers
**Usage:**
```bash
export PULSE_INIT_CONFIG_URL="https://config-server/encrypted-config"
export PULSE_INIT_CONFIG_PASSPHRASE="secret"
pulse config auto-import
```
**Testing:**
✅ Code compiles cleanly
✅ Follows same pattern as existing PULSE_INIT_CONFIG_DATA handling
## Impact
- Completes integration test infrastructure for all instance types
- Enables automated config distribution via HTTP(S) for container deployments
- Removes last TODOs from codebase (no TODO/FIXME remaining in Go files)
Fixes panic: assignment to entry in nil map in PMG polling tests.
**Problem:**
Tests were manually creating Monitor structs without initializing internal
maps like pollStatusMap, causing nil map panics when recordTaskResult()
tried to update task status.
**Root Cause:**
- TestPollPMGInstancePopulatesState (line 90)
- TestPollPMGInstanceRecordsAuthFailures (line 189)
Both created Monitor with only partial field initialization, missing:
- pollStatusMap
- dlqInsightMap
- instanceInfoCache
- Other internal state maps
**Solution:**
Changed both tests to use New() constructor which properly initializes all
maps and internal state (monitor.go:1541). This ensures tests match production
initialization and will automatically pick up any future map additions.
**Tests:**
✅ TestPollPMGInstancePopulatesState - now passes
✅ TestPollPMGInstanceRecordsAuthFailures - now passes
✅ All monitoring tests pass (0.125s)
Follows best practice: use constructors instead of manual struct creation
to maintain initialization invariants.
Implement complete rollback functionality for systemd/LXC deployments:
**Rollback Strategy:**
- Downloads old binary from GitHub releases
- Restores config from timestamped backups
- Service detection (pulse/pulse-backend/pulse-hot-dev)
- Comprehensive health verification
**Implementation:**
Main rollback flow:
1. Create rollback history entry
2. Detect active service name
3. Download old binary version from GitHub
4. Stop Pulse service
5. Create safety backup of current config
6. Restore config from backup directory
7. Install old binary
8. Start service
9. Wait for health check (30s timeout)
10. Update rollback history (success/failure)
**Helper Functions:**
- detectServiceName(): Auto-detect active service from candidates
- downloadBinary(): Download specific version from GitHub releases
- Auto-detects architecture (amd64/arm64)
- Validates download success
- Sets executable permissions
- stopService/startService(): Systemctl service management
- restoreConfig(): Atomic config restoration
- installBinary(): Safe binary installation with backup
- waitForHealth(): Retry health endpoint with timeout
**Safety Features:**
- Safety backup before restore (rollback-safety timestamp)
- Pre-rollback binary backup (.pre-rollback)
- Health check verification post-rollback
- Comprehensive error logging
- History tracking for audit
**Limitations:**
- Binary backup deleted by install.sh (downloads from GitHub)
- Network dependency for binary retrieval
- Config-only backups from current install.sh
**Testing:**
- Compiles cleanly
- Ready for unit/integration tests
Closes Phase 1 technical debt - rollback capability now functional.
Part of Phase 1 Security Hardening follow-up work
Add comprehensive instance-level diagnostics to /api/monitoring/scheduler/health
**New Response Structure:**
Enhanced "instances" array with per-instance details:
- Instance metadata: displayName, type, connection URL
- Poll status: last success/error timestamps, error messages, error category
- Circuit breaker: state, timestamps, failure counts, retry windows
- Dead letter: present flag, reason, attempt history, retry schedule
**Implementation:**
Data structures:
- instanceInfo: cache of display names, URLs, types
- pollStatus: tracks successes/errors with timestamps and categories
- dlqInsight: DLQ entry metadata (reason, attempts, schedule)
- circuitBreaker: enhanced with stateSince, lastTransition
Tracking logic:
- buildInstanceInfoCache: populate metadata from config on startup
- recordTaskResult: track poll outcomes, error details, categories
- sendToDeadLetter: capture DLQ insights (reason, timestamps)
- circuitBreaker: record state transitions with timestamps
**Backward Compatible:**
- Existing fields (deadLetter, breakers, staleness) unchanged
- New "instances" array is additive
- Old clients can ignore new fields
**Testing:**
- Unit test: TestSchedulerHealth_EnhancedResponse validates all fields
- Integration tests: still passing (55s)
- All error tracking and breaker history verified
**Operator Benefits:**
- Diagnose issues without log digging
- See error messages directly in API
- Understand breaker states and retry schedules
- Track DLQ entries with full context
- Single API call for complete instance health view
Example: Quickly identify "401 unauthorized" on specific PBS instance,
see it's in DLQ after 5 retries, and know when next retry scheduled.
Part of Phase 2 follow-up work to improve observability.
Implements structured logging package with LOG_LEVEL/LOG_FORMAT env support, debug level guards for hot paths, enriched error messages with actionable context, and stack trace capture for production debugging. Improves observability and reduces log overhead in high-frequency polling loops.
Task 8 of 10 complete. Exposes read-only scheduler health data including:
- Queue depth and distribution by instance type
- Dead-letter queue inspection (top 25 tasks with error details)
- Circuit breaker states (instance-level)
- Staleness scores per instance
New API endpoint:
GET /api/monitoring/scheduler/health (requires authentication)
New snapshot methods:
- StalenessTracker.Snapshot() - exports all staleness data
- TaskQueue.Snapshot() - queue depth & per-type distribution
- TaskQueue.PeekAll() - dead-letter task inspection
- circuitBreaker.State() - exports state, failures, retryAt
- Monitor.SchedulerHealth() - aggregates all health data
Documentation updated with API spec, field descriptions, and usage examples.
Replaces immediate polling with queue-based scheduling:
- TaskQueue with min-heap (container/heap) for NextRun-ordered execution
- Worker goroutines that block on WaitNext() until tasks are due
- Tasks only execute when NextRun <= now, respecting adaptive intervals
- Automatic rescheduling after execution via scheduler.BuildPlan
- Queue depth tracking for backpressure-aware interval adjustments
- Upsert semantics for updating scheduled tasks without duplicates
Task 6 of 10 complete (60%). Ready for error/backoff policies.
Confirms adaptive scheduling logic is fully operational:
- EMA smoothing (alpha=0.6) to prevent interval oscillations
- Staleness-based interpolation between min/max intervals
- Error penalty (0.6x per error) for faster recovery detection
- Queue depth stretch (0.1x per task) for backpressure handling
- ±5% jitter to prevent thundering herd effects
- Per-instance state tracking for smooth transitions
Task 5 of 10 complete. Scheduler foundation ready for queue-based execution.
Adds freshness metadata tracking for all monitored instances:
- StalenessTracker with per-instance last success/error/mutation timestamps
- Change hash detection using SHA1 for detecting data mutations
- Normalized staleness scoring (0-1 scale) based on age vs maxStale
- Integration with PollMetrics for authoritative last-success data
- Wired into all poll functions (PVE/PBS/PMG) via UpdateSuccess/UpdateError
- Connected to scheduler as StalenessSource implementation
Task 4 of 10 complete. Ready for adaptive interval logic.
Replace string(rune(i)) with strconv.Itoa(i) in hub_concurrency_test.go
for generating client IDs. While this is test code and not a production bug,
it uses the same incorrect pattern that caused the PR #575 bug.
This ensures consistent best practices across the codebase and avoids
confusion for developers who might copy this pattern.
Related: #575
Add regression test for PR #575 to ensure rate limit headers are formatted
as decimal strings (e.g., "10") instead of Unicode control characters.
Also fixes pre-existing fmt.Sprintf argument count mismatch in PVE setup
script (internal/api/config_handlers.go:3077). The template had 28 format
specifiers (excluding %%s escape sequence) but was only receiving 24
arguments. Added missing pulseURL and tokenName arguments to match template.
Related: #575
Adds a one-command Docker deployment flow that:
- Detects if running in LXC and installs Docker if needed
- Automatically installs pulse-sensor-proxy on the Proxmox host
- Configures bind mount for proxy socket into LXC
- Generates optimized docker-compose.yml with proxy socket
- Enables temperature monitoring via host-side proxy
The install-docker.sh script handles the complete setup including:
- Docker installation (if needed)
- ACL configuration for container UIDs
- Bind mount setup
- Automatic apparmor=unconfined for socket access
Accessible via: curl -sSL http://pulse:7655/api/install/install-docker.sh | bash
When the setup script detects TEMPERATURE_PROXY_KEY (proxy is available),
it now shows a clear success message instead of attempting SSH verification.
The verification check doesn't work with proxy-based setups since the
container doesn't have SSH keys - all temperature collection happens via
the Unix socket to pulse-sensor-proxy, which handles SSH.
Now shows:
✓ Temperature monitoring configured via pulse-sensor-proxy
Temperature data will appear in the dashboard within 10 seconds
Instead of the misleading:
⚠️ Unable to verify SSH connectivity.
Temperature data will appear once SSH connectivity is configured.
When pulse-sensor-proxy is available, the setup script now automatically
detects and uses the proxy's SSH public key instead of trying to generate
keys inside the container.
This fixes temperature monitoring setup for Docker deployments where:
- Container has proxy socket mounted at /mnt/pulse-proxy
- Proxy handles SSH connections to nodes
- Setup script needs to distribute the proxy's key, not container's key
The fix queries /api/system/proxy-public-key during setup script generation
and overrides SSH_SENSORS_PUBLIC_KEY if the proxy is available.
Tested with Docker on native Proxmox host (delly) - temperatures collected
successfully via proxy socket.
Changed heredoc delimiter from <<'EOF' to <<EOF to allow bash variable
expansion. Previously $SSH_PUBLIC_KEY and $SSH_RESTRICTED_KEY_ENTRY
were being passed as literal strings instead of their actual values,
so cluster nodes never received the correct SSH keys.
This fixes cluster node ProxyJump setup - now both restricted and
unrestricted keys are properly added to cluster nodes.
The setup script now adds both the restricted and unrestricted SSH keys
to ALL cluster nodes, not just the first one. This makes temperature
monitoring truly turnkey - you say 'yes' to configure cluster nodes and
it automatically sets up both keys on each node.
This ensures:
- All nodes can act as ProxyJump hosts if needed
- All nodes can provide temperature data via sensors
- No manual SSH key configuration required
Fixes turnkey cluster temperature monitoring setup.
When using ProxyJump for cluster temperature monitoring, the jump host
(typically the first cluster node) needs an unrestricted SSH key to allow
connection forwarding. Previously only the restricted key with
command="sensors -j" was added, which blocked ProxyJump.
Now the setup script adds TWO keys:
1. Unrestricted key (for ProxyJump/connection forwarding)
2. Restricted key (for running sensors -j directly)
This allows containerized Pulse to:
- Connect through the jump host to other cluster nodes
- Collect temperature data from all cluster members
Fixes cluster temperature monitoring for Docker/LXC deployments.
Added logic to resolve IP addresses for cluster nodes and include them as
HostName entries in the SSH config. Without this, Pulse couldn't connect
to cluster nodes like 'minipc' because the container couldn't resolve
the hostname.
Uses getent to resolve node names to IPs, with fallback to hostname if
resolution fails (for environments where DNS works).
- Changed SSH key generation from RSA 2048 to Ed25519 (more secure, faster, smaller)
- Added openssh-client package to Docker image (required for temperature monitoring)
- Updated SSH config template to use id_ed25519
- Removed unused crypto/rsa and crypto/x509 imports
Ed25519 provides better security with shorter keys and faster operations
compared to RSA. The container now has SSH client tools needed to connect
to Proxmox nodes for temperature data collection.
The setup script was generating SSH config with IdentityFile ~/.ssh/id_ed25519
but Pulse generates id_rsa keys. Updated SSH config template to use id_rsa
to match the actual key type generated by the monitoring system.
Added middleware exception for /api/system/ssh-config when a valid setup
token is provided, matching the pattern used for verify-temperature-ssh.
The middleware was blocking ssh-config requests before they reached the
handler, even though the handler had setup token validation logic.
The ssh-config endpoint was using RequireAuth which only accepts Pulse
API tokens, but the setup script sends a temporary setup token via the
auth_token parameter. Updated to follow the same pattern as
verify-temperature-ssh: check setup token first, then fall back to API auth.
This fixes the 401 error when the setup script tries to configure ProxyJump
for containerized Pulse deployments.
The setup script was passing pulseURL instead of authToken as the last
parameter, causing 'Authentication required' errors when verifying SSH
connectivity. Fixed parameter order in fmt.Sprintf call.
Security improvements to HandleSSHConfig endpoint:
- Add defer r.Body.Close() for proper resource cleanup
- Return 413 status for oversized requests with errors.As check
- Switch from blocklist to allowlist-based directive validation
- Use case-insensitive parsing with comment stripping via bufio.Scanner
- Add Content-Type: application/json header to response
Codex identified that blocklist approach was insufficient and recommended
allowlist validation to prevent unexpected directives. Only permits the
specific SSH directives Pulse needs for ProxyJump configuration.
Make temperature monitoring truly turnkey by automatically configuring
SSH ProxyJump when running in containers without pulse-sensor-proxy.
How it works:
1. Setup script runs on Proxmox host (e.g., delly)
2. Detects Pulse is containerized but proxy unavailable
3. Automatically configures SSH ProxyJump through the current host
4. Writes SSH config to /home/pulse/.ssh/config in container
5. Temperature monitoring "just works" without manual configuration
Changes:
- Track TEMP_MONITORING_AVAILABLE flag during proxy installation
- Auto-configure ProxyJump if proxy installation fails
- Add /api/system/ssh-config endpoint to write SSH config
- Only prompt for temperature monitoring if it can actually work
- Automatic SSH config: ProxyJump through Proxmox host
Before: User had to manually configure ProxyJump or install proxy
After: Temperature monitoring works automatically after setup script
This makes Docker deployments as turnkey as LXC deployments.
Changed the SSH connectivity check failure message from a scary
"FAILED" warning with complex ProxyJump instructions to a simple
informational message.
Before:
- ⚠️ SSH connectivity FAILED for: ...
- Complex multi-line ProxyJump configuration
- Confusing for users who don't need temperature monitoring
After:
- ℹ️ Temperature monitoring will be available once SSH configured
- Simple list of pending nodes
- Brief note about pulse-sensor-proxy for LXC
- Link to docs for details
This makes the setup experience much more turnkey by reducing
noise and focusing on successful completion rather than optional
features that require additional configuration.
Setup Script Improvements:
- Remove confusing "Could not download installer" warning for proxy
- Skip SSH connectivity check in containerized environments without proxy
- Simplify proxy installation prompts (automatic when available)
- Better messaging for containerized setups
These changes make the setup script more turnkey by reducing noise
and warnings that don't apply to test/development environments or
containerized installations.
Discovery Fixes:
- Always update cache even when scan finds no servers (prevents stale data)
- Remove automatic re-add of deleted nodes to discovery (was causing confusion)
- Optimize Docker subnet scanning from 762 IPs to 254 IPs (3x faster)
- Add getHostSubnetFromGateway() to detect host network from container
Frontend Type Fixes:
- Fix ThresholdsTable editScope type errors
- Fix SnapshotAlertConfig index signature
- Remove unused variable in Settings.tsx
These changes make discovery faster, more reliable, and fix the issue where
deleted nodes would persist in the discovery cache or immediately reappear.
Fixes container detection when Docker health checks are enabled.
Previously, the setup script only matched "running" status exactly,
causing it to skip containers showing "running (healthy)" status.
This prevented:
- Proper detection of containerized Pulse installations
- pulse-sensor-proxy installation for temperature monitoring
- Temperature data collection for affected users
The fix captures the full status output and searches for "running"
anywhere in the output, supporting all status variations:
- status: running
- status: running (healthy)
- status: running (unhealthy)

Track minimum and maximum CPU temperatures since monitoring started.
This provides better insight into temperature trends and cooling
adequacy over time.
Changes:
- Backend: Add CPUMin, CPUMaxRecord, MinRecorded, MaxRecorded fields
to Temperature model
- Backend: Implement min/max tracking logic in monitoring cycle that
preserves values across polling cycles
- Backend: Initialize min/max on first reading, update on extremes
- Frontend: Update Temperature TypeScript interface with new fields
- Frontend: Display min/max range in NodeCard tooltip (e.g., "52°C
(48-67°C since monitoring started)")
- Frontend: Rebuild dist assets
Temperature display now shows:
- Current temperature with color coding (green/yellow/red)
- Tooltip with full min-max range and context
- Min/max tracked in-memory (resets on Pulse restart)
Example tooltip: "CPU: 52°C (48-67°C since monitoring started)"

- Yes/no questions still use y/n (standard convention)
- Fix script input handling to work with standard curl | bash pattern by prioritizing /dev/tty
- Add Raspberry Pi temperature sensor support (cpu_thermal chip and generic temp sensors)
- Add comprehensive documentation for turnkey standalone node setup
- Fix printf formatting error in setup script
Implements automatic temperature monitoring setup for standalone
Proxmox/Pimox nodes without manual SSH key configuration.
Changes:
- Add /api/system/proxy-public-key endpoint to expose proxy's SSH public key
- Setup script now detects standalone nodes (non-cluster)
- Auto-fetches and installs proxy SSH key with forced commands
- Add Raspberry Pi temperature support via cpu_thermal and /sys/class/thermal
- Enhance setup script with better error handling for lm-sensors installation
- Add RPi detection to skip lm-sensors and use native thermal interface
Security:
- Public key endpoint is safe (public keys are meant to be public)
- All installed keys use forced command="sensors -j" with full restrictions
- No shell access, port forwarding, or other SSH features enabled
Fixes two issues with the sensor proxy installation:
1. Local node IP detection now uses exact matching instead of substring matching to avoid false negatives
2. Removes duplicate output filtering in the setup script wrapper
These changes ensure that the proxy SSH key is correctly configured on the local node during cluster installations.
Implements automated cleanup workflow when nodes are deleted from Pulse, removing all monitoring footprint from the host. Changes include a new RPC handler in the sensor proxy for cleanup requests, enhanced node deletion modal with detailed cleanup explanations, and improved SSH key management with proper tagging for atomic updates.
The setup script was restarting the container but never running the
pct set command to configure the bind mount. This meant the socket
was never accessible inside the container.
Now runs: pct set <ctid> -mp0 /run/pulse-sensor-proxy,mp=/mnt/pulse-proxy
before restarting the container to ensure the mount is configured.
Improvements to pulse-sensor-proxy:
- Fix cluster discovery to use pvecm status for IP addresses instead of node names
- Add standalone node support for non-clustered Proxmox hosts
- Enhanced SSH key push with detailed logging, success/failure tracking, and error reporting
- Add --pulse-server flag to installer for custom Pulse URLs
- Configure www-data group membership for Proxmox IPC access
UI and API cleanup:
- Remove unused "Ensure cluster keys" button from Settings
- Remove /api/diagnostics/temperature-proxy/ensure-cluster-keys endpoint
- Remove EnsureClusterKeys method from tempproxy client
The setup script already handles SSH key distribution during initial configuration,
making the manual refresh button redundant.
- Add comprehensive test coverage for alerts package with 285+ new tests
- Implement ThresholdsTable component with metric thresholds display
- Enhance Alerts page UI with improved layout and metric filtering
- Add frontend component tests for Alerts page and ThresholdsTable

- Improve config persistence with better validation
- Expand discovery tests with 333+ test cases
- Update API, configuration, and Docker monitoring documentation
Fixed a fmt.Sprintf argument alignment issue in the PVE setup script that
caused a bash syntax error at the end of script execution. The error
manifested as "syntax error near unexpected token EXTRA" followed by the
serverHost URL.
Root cause: 23 arguments were provided for 22 %s placeholders. An extra
tokenName at position 15 pushed all subsequent arguments off by one,
leaving the final serverHost with no placeholder to fill.
Fix: Removed duplicate tokenName at position 15 and ensured serverHost
is correctly positioned at position 22 for the "Host URL" placeholder.
The REGISTER_JSON template at line 3311 was getting storagePerms instead of tokenName
for the tokenId field, causing 'Missing required fields' errors during auto-registration.
Added tokenName parameter before storagePerms to shift all subsequent parameters.
Fixes #<issue-number>
Fixes two issues found in v4.24.0-rc.1:
1. Setup script menu now uses numbered options [1/2/3] instead of
[I/r/c] for better UX (maintains backward compatibility)
2. Temperature verification endpoint now requires authentication
(wraps HandleVerifyTemperatureSSH with RequireAuth middleware)
These fixes address user feedback and prepare for v4.24.0-rc.2.
Addresses user concern about technical debt: detection code exists only
to handle migration from SSH-in-container to proxy architecture, not to
serve functional purpose of the application.
Changes:
- Add PULSE_LEGACY_DETECTION env var to disable detection without redeployment
- Add explicit removal criteria: v5.0 or <1% detection rate for 30+ days
- Mark all detection code with "MIGRATION SCAFFOLDING" warnings
- Create MIGRATION_SCAFFOLDING.md to track temporary code across codebase
- Document removal instructions for when migration period ends
Backend:
- internal/api/router.go: detectLegacySSH() checks env var and has removal plan
- internal/api/types.go: HealthResponse fields documented as temporary
Frontend:
- src/components/LegacySSHBanner.tsx: Component marked with removal criteria
- src/App.tsx: Banner integration (will be removed with component)
This approach balances user safety during migration (auto-detection catches
rushed admins who skip changelogs) with long-term code cleanliness (explicit
removal plan prevents indefinite technical debt).
Added automatic detection to alert users when they're using the old
SSH-in-container method for temperature monitoring so they can upgrade
to the secure proxy architecture.
**Detection Logic:**
- Checks if Pulse is running in a container (Docker or LXC)
- Checks if SSH keys exist in data directory (/etc/pulse/.ssh)
- Checks if pulse-sensor-proxy socket is NOT available
- Sets legacySSHDetected and recommendProxyUpgrade flags in health endpoint
**API Changes:**
- Added fields to HealthResponse:
- legacySSHDetected: true when old method detected
- recommendProxyUpgrade: true when upgrade is recommended
- proxyInstallScriptAvailable: always true
**Use Case:**
Users who set up temperature monitoring before the proxy feature
won't know they should upgrade. This detection allows the frontend
to show a banner prompting them to re-run the setup script to
migrate to the secure proxy architecture.
**Frontend Integration (to be added):**
Frontend can poll /api/health and show a dismissible banner similar
to UpdateBanner when legacySSHDetected is true, with a button to
view the setup script.
Addresses #123
