Verified by the 100%-coverage tests from the previous commit, written
before this seam existed.
_cpu_table/_dedupe_ram/_ram_table/_gpu_table move to
_usage_report_tables.py with the two constants they own. _md_escape and
_fmt_h move to _usage_report_format.py: both the tables module and the
render module need them, so a third module is what avoids a cycle.
Import sites name the owning module; no re-export barrel.
usage_report.py needed no edit - it imports _fmt_h and _render_report
from the render module, and both names still resolve there.
Evidence the move was verbatim: an AST comparison of all 10 functions
against HEAD reports 10 identical, 0 mismatches. That matters because I
retyped rather than cut-and-pasted, and did briefly introduce a literal
× where the original had × - ruff's RUF001 caught it.
Coverage stays 100% line+branch on all three (15/55/54 stmts, 4/10/14
branches, 0 missed). Test count 43 before and after, summed across the
five files it now lives in - the check that matters for a test split,
since a file outside the runner's glob is silently never collected.
Directory total 143 passed, unchanged.
Ran the real program: a full report from today's atop + pmon logs, every
section rendering through the new boundaries including the RAM sibling
dedupe and its (+20 more) truncation.
Over-cap 41 -> 39. No suppressions; a shared test-helper module was tried
and abandoned because name-tests-test would have needed an exclusion.

43 tests, no production change - the module is byte-identical to HEAD.
This lands separately from the split that follows because a split
verified by tests written in the same commit proves nothing: the tests
would have been written against the post-split shape.
Covers every function, and specifically the branches a happy-path test
misses: zero-length window and cpu_count() -> None in _cpu_table,
non-positive RSS and the CPU/pid tie-break in _dedupe_ram, the sibling
truncation boundary in _ram_table, zero total_samples in _gpu_table,
OSError and unparseable MemTotal in _host_profile, and the single-sample
unknown-interval path in _methodology_section and _render_report.
_host_profile is the only impure function; its /proc reads go through a
monkeypatched Path.open and nvidia-smi is stubbed at the _run seam, so
no test touches the disk or forks.
117 stmts / 28 branches, 0 missed. linux_configuration/tests: 100 -> 143
passing. No suppressions: two ANN401s were removed by typing the helper
kwargs explicitly rather than silencing them, and a mypy ignore went away
with a fallback branch no caller reached.
