Issue #1894 exposed CPU sampling interference between host and Docker reporting loops. Existing tests cover independent collectors and host routing but do not exercise Docker's production dependency entry points.
Interleave the real host, Docker and package-level collectors over synthetic procfs counters. Alternate Docker's include and no-include paths and require each loop to retain a full-interval 5 percent baseline. Production behaviour is unchanged.
Validation: focused test passed; reverting either Docker route to the package-level collector made it fail. After restoration, three focused CPU tests passed with -race -count=3 across dockeragent, hostagent and hostmetrics. git diff --check passed.
