The Windows unified agent exits at startup when HKLM\SOFTWARE\Microsoft\Cryptography\MachineGuid is a braced GUID. gopsutil v4.26.6 reads the value through a fixed 74-byte buffer and rejects any length other than 36, so a braced 38-character GUID fails the whole InfoWithContext call and newAgent aborts with 'fetch host info'. Recover the host info on Windows when the host-ID read is the failing field: read MachineGuid directly, strip braces and fill the other fields from gopsutil accessors, while keeping any non-host-ID failure fatal. Canonicalise Windows machine IDs by removing braces so both forms map to one stable agent identity. Includes agent-lifecycle contract section and focused proof in the registry-accepted agent_new_test.go. Windows recovery is cross-compiled with GOOS=windows; runtime execution on Windows is not qualified in this environment.

Near-synchronous host and Docker reports consumed a shared CPU baseline, measuring collection bursts rather than each module's reporting interval. Retain a collector per host collector and a separate Docker module collector while preserving the package-level convenience API and disk filters.
Add an interleaved-counter regression covering both collection entry points. It fails when routed through the shared baseline and passes with isolated state. All hostmetrics, hostagent and dockeragent tests pass, as do the focused CPU regression tests under the race detector.
