How ATLAS checks itself

Every check ATLAS runs on itself, in one place. They cover whether the matching of census figures to local-area boundaries can be repeated from the publishers' own live files; how the sources score; whether the map rules still hold; what an automated accessibility check found; how the check on written area descriptions treats text from a language model; and what the tests found the last time this copy was built. None of it rates a place.

This summary was built:

The Electoral Division join, checked against live sources

Reproduced against live sources

What that join resolved to in this copy's data

This reproduces a join, not the correctness of the underlying census or boundary data, and it is not a rating of any Electoral Division. A GUID with no matching name is a finding about the source files, not about the place.

Source scorecard

Some detail on this page is generated automatically by ATLAS's own checks, in English only, and has not been translated.

Source scorecard: retrieval, licence, schema and join safety for each source
Source	Overall	Last retrieval	Licence	Schema	Join safety

PASS, WARN and FAIL describe whether a source behaved as expected on the date shown. They are not a judgement of the publisher, and WARN on the join-safety column is a known, worked-around limitation (see the join checks above), not a live fault.

Cartography rules

Some detail on this page is generated automatically by ATLAS's own checks, in English only, and has not been translated.

The cartography rule checks, their result and detail
Rule	Check	Result	Detail

A check passing means the interface behaved as the rule requires on the date shown; it says nothing about whether a rule was the right one to write, and it does not rate any Electoral Division or council.

Automated accessibility check

The counts above are one static-analysis tool's serious and critical findings across the pages and states listed, on the date shown. It does not mean the build is accessible either way; see what this check does not cover below.

What this check does not cover

The sweep runs in English only. It has not been run against the Irish-language interface.
axe-core has no rule for whether an aria-live region announces once or on every repaint. That is behavioural, not something a static-DOM scan can see, so it is not covered even though aria-live regions exist on these pages.
axe-core checks that a tabindex value is valid, not whether the logical or visual order of focus through the page -- including the map's control rail -- makes sense. That order is not covered.

The narrative gate

The narrative gate's pass rate for each writer it has evaluated
Producer	Cases	Passed	Pass rate	Model text accepted

Some detail on this page is generated automatically by ATLAS's own checks, in English only, and has not been translated.

The question reader

How each question reader read a frozen set of questions
Reader	Questions	Read as intended	Agreement	Outcome as intended	Outcome agreement

Outcome as intended counts what the page finally did after the scope check: answered one figure, gave a definition, compared two named places, or declined and said why. That check is the same code for the keyword reader and the model, so this column is what a visitor gets; the reading column is how each reader got there.

Agreement is with a reading a person wrote down in advance, not with a right answer: the query a reading produces is always shown on the Ask page for correction, and the answer to it is computed by code either way. The set includes questions ATLAS must refuse; refusing them counts as reading them as intended.

The test suite

A green suite means the code behaved as its own tests expect; it is not a claim that the tests cover everything worth testing.

What this does not show

None of this rates or scores any place, community or council, and it is not a ranking of any kind. It rates whether the pipeline's own checks passed, never the data itself or the areas it describes.
A check that passes says the code behaved as written, on the date shown. It is not a claim that the underlying public data is accurate, complete or current — see the Sources page for that.
Only what a check itself wrote is left untranslated, even in Irish mode: the cartography rule and detail text, each source's licence/schema/join-safety detail, and the model's rejected text. Labels, dates and connecting words around them are ATLAS's own wording and are translated.

Per-dataset licence, publisher and retrieval age are on the Sources page, not here.
