A green ONLINE status can be accurate even when a phone reports poor cellular signal. In Ilya Mozerov’s diagnostic utility, ONLINE answers a narrow question: does the phone currently have a validated default route? Separate annotations—cell=POOR and idle_s=—describe radio quality and elapsed time since the phone was touched. They warn about context without changing that route verdict.
What does the green light actually claim?
In his September 23, 2026 essay, Mozerov defines ONLINE as confirmation that a validated default route exists at that moment. It does not claim the connection is fast, that cellular reception is strong, or that the phone is actively being used. A poor signal reading therefore does not, by itself, make the route verdict false.

The diagnostic question is: is the field allowed to change the verdict? The design answer is no, when that field describes something other than the condition the verdict measures. The green status and the warning are not contradictory; they answer different questions.

cell=POORdescribes cellular radio quality.idle_s=reports elapsed time since the phone was touched.
These readings help interpret the device’s condition, but neither substitutes for the route check. Keeping the distinction visible prevents a reader from mistaking “online” for “strong signal” or treating a weak radio reading as proof that no validated route exists.

Why annotations should not control the verdict
Mozerov describes an implementation in which two producer functions return annotation tokens. The connectivity verdict and exit code are computed first; annotation values are interpolated into the output afterward. In that arrangement, a problem retrieving a contextual reading cannot silently redefine the primary result.
He says the test suite forces annotation producers to fail and checks two outcomes: the verdict and exit code stay unchanged, while the failed annotation is explicitly rendered as UNKNOWN. That is preferable to inventing a measurement or silently omitting the field. These implementation and test details are Mozerov’s account; they have not been independently verified against the repository.

What the signal readings show—and what they do not
Mozerov says the opening line, cell=POOR and idle_s=60576, came from a vet run on September 22, 2026, at 15:37 UTC. He notes that the exact 16-hour idle figure was not independently reproduced.

These are the author’s dated observations, not durable specifications or independently confirmed measurements. Signal changes over time, so a reading from one session should not be treated as a permanent property of the phone or its connection.

A separate caveat: the --json flag
The verdict/annotation separation does not resolve every behavior of the utility. Mozerov discloses that the tool does not handle arguments: requesting --json falls through to normal pipe-delimited text rather than returning JSON. The exit code can still look successful, so a machine caller cannot tell from that result that its requested format was refused.
According to Mozerov, existing state-file consumers read text and none was broken. That limits the reported impact, but it does not make the format request work: the refusal is silent. This is a command-line interface limitation, distinct from whether the connectivity verdict correctly represents a validated route.

The useful design principle
A status indicator earns trust by stating precisely what it establishes. Contextual readings can—and often should—remain visible beside it, including readings that raise concern. The important boundary is that annotations describe other conditions; they do not change a verdict whose scope is specifically route validity. As Mozerov puts it, “The publishable sentence is not my green light lied. It is my green light told the truth and still warned me.”
