That conflated two distinct cases:\n\n* cputime \u003c 0 -- the underlying counters went backwards (cgroup\n  or libvirtd restart, container recycling, an NTP step, or a\n  daylight-saving transition). The sample is unreliable and\n  reporting 0% is misleading. Skip the sample with a warning and\n  leave the cached counters untouched, so the next sample is\n  compared against the last known good reading rather than the\n  reset counters.\n\n* cputime \u003d\u003d 0 -- no time has elapsed between samples (paused\n  host, or the driver returning identical counters back-to-back).\n  The per-state percentages cannot be recomputed, but reporting\n  0% would suggest the CPU just idled. Report the last known\n  percent values preserved from the previous cputime \u003e 0 sample\n  instead. The cached counters are still refreshed so the next\n  sample can resume normal deltas, and the percent values in the\n  cache are preserved across that update.\n\nThe percent values are also written into the cache alongside the\ncounters on each successful sample so they remain available as\n\"last known\" values for any future cputime \u003d\u003d 0 sample.\n\npopulate_metrics() now skips a metric whose key is absent from the\ninternal data dict, so the cputime \u003c 0 path (which returns early\nwithout populating the percent metrics) does not raise KeyError.\n\nTwo unit tests cover the zero and negative delta paths, and a\nthird guards the negative-then-recovery case to ensure a skipped\nsample does not clobber the cache.
