One gate, three incidents behind it, all from the barakoCMS admin theme change on 1 September.

An accessibility or contract check that only ever loads an empty or fully mocked page has not checked anything that needs data to exist.

  • Status badges rendered white on white. The tint classes took their text colour from a token that exists for white-on-solid buttons, over a 10 percent alpha wash. The axe case for that screen stubs an empty list, so no badge had ever rendered under the gate.
  • A nav count changed every link's accessible name from Entries to Entries 148. Every mocked suite passed, because a mocked list has no total and renders no count. Only the unmocked pack that drives a real API saw it.
  • A test asserting "no data source shows no number" passed against a deliberately broken build, because it asserted before the count query resolved. It was measuring an unpopulated render.

The third is the one that makes it a gate rather than a bug report: the test was written specifically to prove the absence case, and it proved it by accident of timing.

Also records the measurement half, because it is cheaper than rendering: contrast is arithmetic, so compute every foreground against every surface it can land on. The same palette shipped faint at 4.25:1 against one of its own three surfaces, and no rendered check would have caught that either, because nothing in the suite put that text on that surface.

Answering the document's own three prompts: I believed an axe pass meant the palette was safe; what went green that should have gone red was every accessibility case on a screen whose badges were unreadable; and what caught it was a person measuring, plus one unmocked test pack, which is why the mechanism is written down here.

Summary by CodeRabbit

  • Documentation
    • Added guidance requiring accessibility and contract checks to render the data-driven states they validate.
    • Documented examples of defects that can be missed by empty or mocked pages, including status-badge contrast and accessible-name changes.
    • Added recommendations for ensuring each screen state is covered with representative data and for separately checking foreground/background contrast combinations.

Three instances in one afternoon, all in one admin UI during a theme change:
status badges white on white behind an axe case that stubs an empty list, a nav
count that changed every link's accessible name where no mocked suite renders a
count, and a test that asserted before its query resolved.

Plus the measurement half, since contrast is arithmetic and the same palette
shipped a token at 4.25:1 against one of its own surfaces.

Use standard axe terminology.

Replace “The axe case for that screen” with “The axe test for that screen” or “the axe check”. “Axe case” is ambiguous and makes the incident harder to understand and search.

Suggested wording
-  that screen stubs an empty list, so no badge had ever rendered under the gate. Fixing it meant making it render a row of every status; reverting one class then turns it red on
