The entry point now holds only the parser, mode dispatch and main. Three
modules take one concern each: _usage_report_logs (where the logs are,
the state file, per-day segment planning), _usage_report_emit (preflight,
stdout, clipboard), _usage_report_run (the two run paths and the
aggregation they drive).
Verified by the 100%-coverage tests from the previous commit. An AST
comparison of all 22 top-level defs and classes reports 22 identical, 0
mismatches.
All four modules hold 100% line+branch. 204 tests before and after. Both
CLI modes were run against the machine's real logs, which is the check
the unit tests cannot make: they stub the collaborators, so only a real
run proves the new import graph resolves.
Two lessons, recorded because the next target is a 498-line file:
This cut was too big. Two names had to be relocated after their first
placement created an import cycle, and four modules' worth of monkeypatch
targets needed re-pointing. A smaller first slice would have been cheaper.
Patching a moved function must target the module whose namespace resolves
it - the caller's, not the one it was moved to. Getting that wrong on
_run_since made main() call the real function, which read the actual atop
logs and hung the suite rather than failing.
Three import bugs (Path and _fmt_h left under TYPE_CHECKING but used at
runtime, dataclass missing where _Aggregates landed) were caught
immediately by the coverage from the previous commit.
Over-cap 38 -> 37.
