+## Ruling on design r1 (sage-2487)
+
+Duckworth approved Morgana's design r1 (3e9939b7b) as D1: a separate human and reader verb `thread.claims`,
+with `agents` unchanged, under conditions C1-C3 (duckworth-0118, agents/duckworth/work/row1782/DESIGN-r1.md
+at 13fb9abc5). The brief allowed that shape. Brief item 5's pin moves to `thread.claims`, as C3 records.
+Row 277 builds it.
+
+The Console doesn't show thread claims under D1, and an owner who uses only the Console won't run
+`mosaic agents`. So PRD :1083-1084 isn't met until the Console shows them too. That's the follow-up brief
+below, with the same bind as row 277.
+
+## Brief: the Console shows thread claims
+
+Chained on row 277. Start from refactor after 277 lands.
+
+What to build:
+
+1. The Console's Agents view gets a "Thread claims" section for a human or reader session. It reads
+   `thread.claims` and lists each held claim: thread id, holder run, harness and claim time.
+2. The existing role rows (webui public/bus.js :447, :462, :474) keep their shape, counts and order.
+3. No message body and no thread name a user wrote appears in the section.
+4. An empty result shows an empty-state line, not an error. A refusal from `thread.claims` shows the
+   refusal and leaves the role rows intact.
+
+Tests:
+
+- The section lists a held claim and drops it after release.
+- Role rows and their counts are byte-equal to before for the same store.
+- No message body or user-written thread text in the rendered section.
+- A refused `thread.claims` call leaves the role rows rendered.
+
+Mutants, each killed by a named test:
+
+- M1. The section is not rendered.
+- M2. Thread claims are counted into the role totals.
+
+Gate: Webby approves the manifest. The touched test files run whole, the webui and bus suites and every
+scripts/test-*.sh are green on Sage's gate, and the mutants are killed. No user thread goes live before this
+row lands.
