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.
