Live-system developer experience audit using browse tool. Tests all 8
dimensions aligned with /plan-devex-review for boomerang comparison
(plan said 3 min TTHW, reality says 8). Each dimension marked TESTED,
INFERRED, or N/A with evidence. Scope-aware: declares what browse can
and cannot test, falls back to file artifacts for untestable dimensions.
