New table-driven tests in test/unit/main.test.js: humanDuration, the
figure and sparkline colours either side of each latency boundary, a
target's min, max, average and median over empty, all-unreachable and
mixed histories, and the four health states either side of their
thresholds. src/main.js exports the four names they need.
package.json gains a test script, which script/frontend-test runs with
the dot reporter and, if a test fails, again with the spec reporter
before failing. NODE_OPTIONS picks the reporter, since yarn appends its
arguments after the test files.

Each target check now times out after 80% of the refresh interval, 24
seconds at 30 seconds, where it was capped at 3 seconds, so slow, far
targets are recorded with their real time. Rounds never overlap: a
round gives up the last round's checks if they are still waiting, which
happens only when a round starts early, after an interval change or
when the recovery probe finds a target answering. The probe still
checks every half second, giving up its previous checks, so they do not
pile up.
The frontend has its first unit tests, run by script/frontend-test with
Node's built-in test runner on a mocked clock. index.html now links
src/styles.css, which src/main.js imported, since Node cannot import
CSS.

Root make check, and with it the pre-commit hook, now gates the Go
backend too. The backend's Makefile targets are shims over
backend/script/*; script/cibuild builds both images and is the
workflow's only build step. Root make test runs both halves within one
30-second timeout.
Root make lint runs golangci-lint only in Docker, by building the lint
stage of Dockerfile.backend without the cache; the .golangci.yml drift
check moved into backend/script/lint. script/bootstrap installs no
linter: it reuses a Go at least as new as backend/go.mod asks for,
otherwise installs the pinned, hash-verified release, linked into
~/.local/bin without replacing anything it did not create. With VERSION
unset or empty, the backend version falls back to git describe inside a
git checkout, then to dev.
