Stacked on #2609; until it merges this branch also carries its commit, and the change here is the last commit. ## Why The registry merges a physical disk's rows (Proxmox, host agent SMART, Unraid inventory), choosing the temperature by source preference and merging collection states separately. When two rows carry different temperatures, the shown value could sit under the other row's `available` state. A real case: a node whose disk temperature Proxmox collects now (`proxmox_node_smart`, 40) and whose linked host agent has gone silent (retained 72, `unavailable`). In either ingest order the merged disk showed **72 labelled available**, so risk, history and the UI treated the frozen reading as current. ## What - `pairPhysicalDiskTemperatureState` runs at the end of each merge step. When the merged state says collected but the row the shown value came from says it was not, the merged state becomes that row's own. - It never changes a value and never grants availability, so it cannot revive a withdrawn reading or override a resumed agent's fresh one. - Rows with the same value keep the merged state, so the agent's own withdrawal still supersedes the Proxmox copy (#2593). - With that guarantee the Unraid-native row no longer needs to withhold `available` (#2609 restricted it), so it carries the same derived state as a SMART row borrowing its reading. ## Known limit This is exact for the two rows of one merge step. The merged disk keeps one state per field, so with three or more rows for one disk, a withdrawal that an earlier step replaced is invisible to a later step. Sol found two such counterexamples, both needing three rows (one also needs coincidentally equal values, the other a legacy agent plus two Proxmox rows). Closing that needs each reading's own state tracked across merges, and that redesign is filed separately. Preferring another source's current value instead of the retained one was tried and dropped: it needs an ordering between same-source states that the rows do not record, and each version reopened a withdrawn reading somewhere. ## Tests - `TestPhysicalDiskMergePairsTemperatureWithItsCollectionState`, in both ingest orders: - silent agent against a collected Proxmox reading, and against no Proxmox reading - reporting agent - silent agent against a Proxmox copy of its earlier reading, with and without SMART attributes - resumed agent against a Proxmox copy of its withdrawal - standby agent against a Proxmox copy of its pre-sleep reading - `TestPhysicalDiskMergeNeverPresentsAWithdrawnTemperatureAsCollected`: three distinct-valued withdrawn or stale rows in all six orders. - `TestUnraidInventoryRowDoesNotMaskTheSMARTRowState`: the Unraid inventory's `available` no longer lends itself to a SMART row's uncollected reading. - Without the rule, the peer-reported case, the Unraid masking case and one three-way order fail.

Start here
- Install Pulse — signed Proxmox/Linux installation, Docker, Docker Compose, Kubernetes, and first-run setup.
- Production deployment and security — least-privilege Proxmox setup, root-agent boundaries, discovery, supply-chain verification, plan limits, scale evidence, and a rollout checklist.
- Upgrade from Pulse v5 — migration prerequisites, rollback, agent continuity, and post-upgrade checks.
- Releases and update channels: choosing Stable or Preview, beta and RC expectations, and how releases are tested and promoted.
- Configure Pulse — authentication, notifications, discovery, retention, and system settings.
- Deployment models — data locations, lifecycle, and differences between supported deployment paths.
- Troubleshooting and FAQ — common failures, diagnostics, and operator questions.

Platforms and agents
- Proxmox Backup Server
- Proxmox Mail Gateway
- Docker and Podman
- Kubernetes and Helm
- TrueNAS SCALE and CORE
- Unified Agent
- Agent security
- VM disk monitoring
- ZFS monitoring
- Temperature monitoring
VMware vSphere support is early access. Current builds expose dedicated vSphere inventory and recovery context, but operators should validate the integration against their own vCenter before production use.
Monitoring and operations
- Metrics history
- Recovery data
- Webhooks
- Automatic updates
- Centralized agent management (Pro)
- Operational trust model
- Current product screenshots
Pulse Intelligence
- Assistant, Patrol, and external-agent overview
- Patrol modes and safety
- Assistant safety model
- External agent HTTP and MCP substrate
Patrol watch-only analysis is available on Community with a local model or the operator's own provider. Investigation and governed fixes require the relevant Pulse Pro capabilities.
Security, privacy, and access
- Production deployment and security
- Security review scope
- Authentication and credential storage review packet
- Security guide
- Privacy and telemetry disclosure
- OIDC and SSO
- Proxy authentication
- Role-based access control (Pro)
- Audit logging (Pro)
- Reverse proxy configuration
- Code-signing policy
Plans and managed access
- Community, Relay, and Pro capabilities
- Relay and Pulse Mobile handoff
- Multi-tenant organizations (Enterprise/custom)
- Provider-hosted MSP operations (request-assisted)
Pulse Cloud is not generally available. Ordinary self-hosted Pulse remains the primary installation path; MSP and Enterprise access are explicit commercial paths rather than defaults in self-hosted setup.
