Real 'gh api --jq .[].created_at' on an empty collection emits no lines;
the stub printed a literal '[]', which under byte-wise collation sorts
after ISO-8601 timestamps and poisoned the PR-surface probe's
last_activity. Route the synthesized empty array through the same jq
projection as a present fixture, and pin the test's collation so the
verdict cannot flip with the runner's ambient locale.

Issue side: invariant-1 composition, the reclaim clock stopping under a
pending ruling (with a flag-free reclaim control), the stale heal, label
churn invisible to the activity clock, the surface-level nudge reset, and
no edit anywhere naming the flag. PR side: the wired nudge riding the
stale sweep's activity computation, one nudge across two sweeps, #51's
stale skip intact.
