 - **A-112** (§633, A-71; principle 7, one way per kind of part) A process reads its settings as the builder does
   (A-71): a file its manifest declares, its content `${config:<key>}`, read at its start; so the node-engine reads
   `recovery-wait-minutes` from such a file, default 90 when it is missing. A bundle keeps `stdio.Config`.
+- **A-113** (§297, §560, §541; principle 3, failure is loud and leaves nothing broken) A revert whose restore fails
+  after `Env.Stop` starts the newer build again and holds the move, saying why; a module is never left stopped. A form
+  change whose entries are not yet answered waits for them, never moves without its restore point. The hold says
+  `wait-held` (§541) as every wait does.
