The cargo tests put web.rs at 17% and daemon.rs at 10%, because the browser suite, which drives the API, ran a daemon nobody measured. `sh scripts/coverage.sh api` builds an instrumented ipx and ipx-directory in the capped coverage container and runs the browser suite here against them (IPX_API_COVERAGE): web.rs is at 80% and daemon.rs at 77%. What it does not reach: access.rs (Cloudflare Access, 0%; its unit tests 73%) and the directory's public pages (site.rs, 4%). The coverage image is Ubuntu 24.04 now, as code-server is: built on Debian trixie, the binaries needed glibc 2.41 and code-server has 2.39. In that mode the suite starts those binaries rather than building its own, its tests' `ipx` commands too (global-setup's IPX_BIN), passes LLVM_PROFILE_FILE to both servers, and stops them with SIGTERM, since an instrumented binary writes its profile as it exits and Playwright otherwise kills them outright. Reports go to target/coverage/cargo, api and page. Each run ends with scripts/coverage-metrics.ts, which writes every suite's lines covered and in all, by crate, to node-exporter's textfile directory; the monitoring project's node-exporter now reads it (one flag, its compose file backed up beside it), so Prometheus keeps them as ipx_coverage_lines, and the iPX dashboard's Coverage row draws them: each suite now, over time, and by part. The cargo tests' totals hold their own code, which runs whole, so they read higher than the code alone; the panels say so. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
