Red test first: a raw TCP listener that never speaks HTTP must read down under an http probe (up under tcp), while a real HTTP server reads up. This test caught a real hang — the backgrounded listener inherited the test runner's stdout pipe and held it open; fixed by redirecting its output and killing both listeners in teardown. scripts/homepage-status.py: probe() now dispatches on method. http does an urlopen (any HTTP status = up; no connection = down); tcp connects. The checker is now complete: tcp + http + wip + atomic write + generated_at. Remaining slices: services.json schema, the pages + theme + toggle, the Caddyfile (validate + two hashes), the git-driven deploy.
