Code metrics baseline: earthworm

Measured by Tezcatl 0.1.0 (Ubuntu clang version 22.1.8 (++20260714014902+ca7933e47d3a-1~exp1~20260714135019.80)) from the compilation database in earthworm: 929 translation units parsed, 0 with errors. 120 database entries for other languages (such as Fortran) were not parsed. 1584 of the 2910 source files under the root were parsed, as a unit or through an include. The other 1326 (parsed is no in files.csv: code for other platforms, parts the build skips) count toward lines of code and nothing else. Every figure is defined in Tezcatl’s docs/metrics.md; the same data, complete, is in report.json and the CSV files next to this report.

Complexity thresholds: flagged over 10, high over 20. Test code is recognised by **/test/**, **/tests/**, **/*_test.*, **/test_*.*; it counts toward test lines only.
