🔴 **Sign-up requires a year of birth and no instrumented test filled it.**
`submit` is `enabled = … && (!registering || birthYear.length == 4)`, so
the button was DISABLED — and `performClick()` on a disabled Compose node
does not throw, it does nothing. Every sign-up in this suite has been
tapping a dead button since the age gate landed, failing two minutes later
with 'nav-contacts did not appear' and no error anywhere on screen.
Nothing was wrong with the app. The suite simply stopped being able to
create an account, and a failing instrumented suite reads as a flaky one.
Also fixes the skip counter in scripts/instrumented.sh: it grepped a bare
SKIPPED, which matches Gradle's own `Task … SKIPPED` lines, so a verdict
written to stop a skip being read as a pass was inventing skips instead.
