174 tests covering URL normalization, FTS5 query sanitization, SSRF/CSRF
guards, sharing-mode logic, DB schema and upsert paths, handler
end-to-end flows, and gateway body-size / mesh-whitelist guards. Each
recent bug-fix commit (6ffd38d, 1bc695f, 8dffd8c) has an explicit
regression test in test_regressions.py. One xfail documents a minor
latent bug in clean_url where port 80 is not stripped from upgraded
https URLs.
