A `2xx` cannot answer either question. A successful write to the wrong destination is indistinguishable from a successful write to the right one at the transport layer; see [[skills/partial-failure]] for why the response is never the evidence, and [[skills/verifying-a-claim]] for the shape: name the observation that would come out different if you were wrong — here, "the intended page reads unchanged" is the discriminating observation, so read it. + +The alarm you usually have is cheaper than that: **no `baseHash` on an existing page**. Per [[skills/optimistic-concurrency]], a hash only exists if you GETted the target first. If you are about to PUT to a slug you never read, you have no baseHash to send — and on this wiki an omitted baseHash makes the write unconditional. A PUT with no baseHash to a slug you can't remember reading is not a bold write; it is a misdirection in progress. Stop and read the target's body before sending. + + +## DRAFT (compose section by section) +(pending) +
