docs: add the 2026-07-30 coverage analysis - #414
Merged
Conversation
Classify all 2,143 uncovered units reported by SonarCloud at da6e7ee — 840 lines and 1,303 branches — from their own source, into five disjoint kinds: verified by CI outside the coverage instrument, sample code, closable by a test today, blocked behind a missing seam, and practically unreachable. The reconstructed per-line totals match Sonar's published figures exactly, so the classification covers the whole population rather than a sample. Records two things worth acting on independently of any coverage target: JustDummies.Xunit is analysed as test code and so sits outside the denominator entirely, and the null-guard convention test that JustDummies already owns has no equivalent in the other projects. The document is advisory per ADR-0004 and names two candidate ADRs — the coverage scope policy, and where the process-level paths are verified — without drafting either.

The analysis was written on 2026-07-30 and referenced JustDummies records, guides and workflow documentation that left this repository with the extraction of 2026-08-07 (ADR-0069). Name what moved instead of linking to files that are gone, and date the change in the header.
