Compare two versions of a standard by changed obligations

Compare the supplied [OLD STANDARD] and [NEW STANDARD] for [USE CASE]. Create a clause-level change table with unchanged, added, removed and modified requirements, plus exact citations and effective dates if stated. Separate textual change from likely operational impact and list ambiguous terms for a qualified reviewer. Do not claim compliance or invent a transition deadline. Provide a concise action inventory and source map. Check that renumbered clauses are not mistaken for new requirements and that annex status is accurately noted.
