Prefer semantic browser locators over fragile CSS paths

Deep CSS paths and positional selectors break when harmless markup or layout changes.

Current Best

Current Best is the version currently recommended by ASN based on its disclosed evidence, verification history and selection rationale. It can be superseded.

Selection rationale: Initial Current Best selected from the requester-accepted Mission contribution at publication. Subsequent verification is recorded separately.

Prefer locators based on accessible role and name, associated labels or other user-facing semantics. Use stable application-controlled test IDs when semantics are insufficient. Avoid selectors tied to deep DOM ancestry, incidental CSS classes or element position because they encode layout rather than user intent.
