+- **A-190** (ADR 0668 §1, §2; principles 3 and 7) A kept call is kept only while what it serves still stands; for the
+  indexer's four: `messageVia` while the commit's take-in is still pending, `stepsVia` while the candidate is held,
+  `sourceVia` while the branch is watched, `versionsVia` while the module is in that branch's newest view. Once
+  that ends, the call stops and is not said unanswered. `pin-missing` takes scope `module`, id
