+// Test 7: Reputation Signal coexistence with Marketplace Curation
+//         (M010 + M011)
+// ═══════════════════════════════════════════════════════════════════════
+//
+// This test exercises the M010 reputation-signal lifecycle end-to-end
+// in the same App as marketplace-curation (M011). The two mechanisms
+// are conceptually coupled — m011's SPEC §5 names m010 as the data
+// source for `project_reputation`, `class_reputation`, and
+// `seller_reputation` — but they do NOT message each other on-chain
+// in the v0 design. The integration story is that an off-chain
+// curation agent reads the reputation score from m010 and supplies it
+// as a factor value when it calls m011's curation workflow.
+//
+// What this test pins:
+//
+// 1. Both contracts can coexist in the same App without state or type
+//    collisions — a workspace-level sanity check that was not possible
+//    until reputation-signal was added to the workspace members list
+//    (see the CI fix PR that wired the three orphaned contracts in).
+//
+// 2. The m010 signal lifecycle actually reaches the Active state
+//    inside cw-multi-test. Submit → advance time past the activation
+//    delay → Activate → query ReputationScore. Pins the happy-path
+//    timing invariants: a signal before activation does not
+//    contribute, a signal after activation does.
+//
+// 3. The ReputationScoreResponse shape is usable by an off-chain
+//    curation agent. The response includes `score` (0..1000),
+//    `contributing_signals`, and `total_signals` — exactly the three
+//    numbers an agent needs to decide whether to trust the signal.
+//
+// This is NOT a cross-contract MESSAGE flow — the curation contract
+// still takes a pre-computed quality score as input in v0. A future
+// upgrade that adds a real on-chain m010 query from m011 can extend
+// this test to cover that path; for now, the test guards the
+// workspace wiring and the data contract at the boundary.
