Illustrates user-guide.md §7 and
ontology.md §6.3. Nothing here is implemented; the
data below is fabricated to demonstrate the encoding rules. Every state
carries a glyph, a label and a colour, so colour is never load-bearing.
1. The query surface
Move Location from a single network up to the country and watch the
headline flip from “no” to “yes” while the denominator grows. That is
max being monotone in selection size: widening can only raise the
answer, which is why the count and the argmax are not optional decoration.
2. A single finding, artefact first
The state label is present but subordinate. The sentence a reader repeats to
someone else is the artefact sentence, and it is the one that survives contact
with the operator being described. Mechanism confidence routinely exceeds
blocking confidence, so the mechanism leads.

Blocked
m.facebook.com · AS12345 Example Telecom · Italy · 1–14 Mar 2026
DNS resolution for m.facebook.com returned
10.10.34.36, an address inside the provider's own network
that does not host the site.
Seen in 37 of 42 measurements from this network over 14 days.
Confirmed by a matching blockpage fingerprint (it_isp_blockpage_v2).
What this means for you
Your provider's DNS is returning a false address. A different resolver, or
encrypted DNS, may reach the site.

rule country_consistent_blockpage
Contrast the same layout when the evidence is thin. The state changes
rather than carrying a confidence caveat, because readers keep labels and
discard qualifiers.
3 measurements over 14 days, from 1 probe. Below the
threshold needed to distinguish blocking from an outage.
What this means for you
We cannot say. This is not evidence that the site is reachable.
3. State vocabulary
Seven states, matching the focal elements in ontology.md §6.3
exactly, so the model and the interface share one vocabulary. “Not enough
data” is hatched rather than tinted, because rendering an empty cell as a pale
positive is the most damaging default available here. “Blocked on some
networks” is the aggregate-only state: it is the lattice join for a selection
containing both blocked and reachable cells, and it exists so that aggregation
never has to emit an incoherent (1, 0, 1) triple.
4. Time series
Three rules encoded below: gaps in coverage are drawn as gaps and never
interpolated across; the measurement count is always visible as a strip under
the axis; and changepoints are marked on the series with their mechanism
rather than filed in a separate list. The band is a 90% credible interval, so
its width falls out of the measurement count instead of being chosen.
5. Network × layer matrix
The default view for any multi-network selection. Method and locus vary by ISP
within a country, and that variation is usually the finding; collapsing it to
one national label destroys it. The HTTP column is hatched throughout because
there is no HTTP verdict implemented yet, which is the honest rendering of a
missing layer rather than an absent one.
