How it works

Sum repeated line counts, preserve compatible checksums and rebuild LF/LH totals per source file.

The sample merges two a.c records into two covered lines, with counts 1 and 3.

Limits

Line coverage only. Function and branch records are counted as omitted and excluded from the download. Paths must already use the same naming; conflicting line checksums are rejected.
