Content refresh or retirement

IF demand remains valuable
AND facts/format/evidence are stale
AND improvement value exceeds cost
THEN refresh.

IF several assets overlap
AND one stronger canonical can cover the task
THEN merge and migrate.

IF the page has no distinct task
AND no meaningful demand, value, links, or dependency
THEN retire with the appropriate technical state.

IF the page serves a valid user need despite low search traffic
THEN preserve it
AND do not judge it only by SEO metrics.
