atop's `-P PRC` output inserts the clock-tick rate (HZ=100) between the
`state` and `utime` columns. Both the Python parser and the native C
aggregator read that constant as utime for every record, charging a flat
1 CPU-second per record — so cpu_seconds collapsed to pid_count and
short-lived fork-storm commands (xset, dd, chronyc) topped the CPU table
(xset showed 67h). The old test fixtures lacked the HZ field, so code and
tests agreed on the bug.
- _parse_prc / atop_agg.c: read utime/stime past the HZ field (after+2/+3,
tokens[10]/[11]); bump the length guards accordingly
- restore C/atop_agg (deleted in 89b4f59) under linux_configuration/C/,
where the build path resolves; corrected test fixtures to include HZ
- _atop_agg_binary: fall back to the Python parser when the C source tree
is gone instead of trusting an orphaned cached binary
- add regression tests proving HZ is not summed as CPU
- bundle the in-progress since-last-report multi-day aggregation (segments,
-b/-e bounding, persisted state, window merging) and its tests/conftest
- meta: gate linux_configuration/tests in pytest_changed_packages.py
Verified by running usage_report.py --date 20260604: Top CPU now led by
SkyrimSE; xset/dd/chronyc fall to ~0. C unit tests + full pytest suite green.
