Stacked on #2715 (its commit is this branch's parent; whichever lands first, the other still merges). ## Problem A manual link merges two resources for display, but `PersistIdentityPins` pinned the merged identity. A link primary was pinned with the folded resource's machine key, and the store's one-owner-per-key rule deleted the folded resource's own pin. For a Proxmox node with a qualified endpoint (`https://pve1.example.test:8006`) linked to a host agent, the node's pin records the endpoint, so the next rebuild completed the agent's machine key from it, minted the agent's machine-derived ID and merged the two by ID before the link applied. With the node as primary, succession then rewrote the link into a self-link on the agent's ID; in either direction, removing the link left the pair merged. Reproduced through `MonitorAdapter.PopulateSnapshotAndSupplemental` with a `MemoryStore` on #2715's head. ## Change - `applyManualLinks` captures each side's own pin before the merge (`recordLinkOwnPin`, first capture per rebuild wins), and `PersistIdentityPins` writes those instead of the merged projection, keeping a pinnable folded side pinned under its own canonical ID. - Link sides write through a new `ResourceStore.ReplaceResourceIdentityPins` (both stores). Like an upsert the row keeps fields the side's own pin leaves empty, but it drops a strong key another resource holds this rebuild, which is how a key an earlier release borrowed from the merged identity leaves the row. - A folded side drops a key a live resource or an earlier folded side already holds instead of trading it every rebuild, and writes no pin when that would cost it its machine evidence (a cluster-only row would be open to cluster-slot succession). - Proxmox auto-links (LinkedAgentID / identity matcher) merge before any manual link applies, so their boot-window pins are unchanged (`TestIssue1753*`, `TestMonitorAdapterRebuildPersistsIdentityPins` pass). Known limits, written into the contract: a node row an earlier release already filled with the agent's key still merges the pair by ID while the node can complete from it; two live resources sharing a strong key still alternate, as on main; evidence a later record pass of the same rebuild merges into an already-joined row reaches neither side's pin. ## Verification - New tests in `registry_merge_policy_test.go` (standalone and clustered node, both link directions, three rebuilds with no steady-state pin writes, then unlink separates the pair; shared-key, kept-field, hostname-guard, machine-loss and borrowed-key cases) and `store_test.go` (replace vs upsert on memory and SQLite). - Each new test fails against #2715's runtime files via `go test -overlay`; each guard rule fails its own test when removed. - `internal/unifiedresources` full package, `internal/monitoring` link/identity tests, `internal/api/resourceapi`, `go build ./...` and `go vet` pass. - Contract: `unified-resources.md` clause 25 and "Operator links reach record-ingested resources".

Start here for installation, platform setup, security, operations, and Pulse Intelligence. Commands, configuration keys, image names, API fields, and product identifiers remain untranslated in localized guides.
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.
