no-conflicting-aria

Disallow aria-live values that conflict with the implicit live region behavior of a declared role.

✅ Fixable · Recommended: warn

Why

Certain ARIA roles imply a specific aria-live value. For example, role="alert" implies aria-live="assertive". Setting a different aria-live value creates a conflict that can confuse assistive technologies.

Examples

❌ Incorrect

<div role="alert" aria-live="polite">Error!</div>
<div role="status" aria-live="assertive">Updated</div>
<div role="log" aria-live="assertive">Log entry</div>

✅ Correct

<div role="alert">Error!</div>
<div role="alert" aria-live="assertive">Error!</div>
<div role="status" aria-live="polite">Updated</div>
<div role="status">Updated</div>

Autofix

Removes the conflicting aria-live attribute.

- <div role="alert" aria-live="polite">Error!</div>
+ <div role="alert">Error!</div>

Role → Implied aria-live Mapping

Role	Implied aria-live
alert	assertive
status	polite
log	polite
marquee	off
timer	off

When the aria-live value matches the implied value, no violation is reported (it's redundant but not conflicting). Dynamic aria-live values are skipped.
