- Forbid `continue-on-error` in ci.yml: that mutation left every test green,
and a failing step would turn the commit status green in silence.
- boot-from-copy.sh refuses a port already held by something else (any curl
exit other than 7). Without it, the wait loop could reach the neighbour and
assert on a server it never started — the new test reproduces exactly that
when the check is removed.
- Pin every require of the COPY'd runtime modules at column 0, with no
dynamic import: the boot check only calls /health, so it only proves the
modules loaded at startup.
