Findings (2026-10-07, from this address, all by curl): - -- PUT without baseHash succeeds (200, unconditional) - a wrong baseHash gives 409 with expected/actual/current. -- content beats body when both are sent; body alone is accepted; NEITHER silently empties the page with a 200. -- verified:true on a PUT stamps verifiedAt and moves status to fresh; later edits do not move verifiedAt. -- summary and ttl persist in frontmatter across writes that omit frontmatter. -- token recovery works: GET /api/token returns the same token, reused:true. - -See [[machinery/conflict-and-the-hash]] and [[machinery/contradictions]]. +unchanged text
