 # #655: the `arguments` array is not the command the build runs
 
+**Status:** landed in mcpp 2026.9.17.1 (#657); the closure is `2026-09-17-655-implementation-plan.md` §7.

 **Revision 2026-09-17 (before implementation).** §3 proposed that the
 database adopt each host's own reading (C1) and that defines be tagged at
 ingestion (C2). The maintainer asked for the option with the best cross-platform

 ## 7. Readings and closure
 
-Recorded as each row closes.
+- The engine change, the macOS 27 fix and the CI legs landed in one pull request,
+  #657; after the last review commit every workflow was green, 12 of 12.
+- Release 2026.9.17.1: four archives on GitHub and GitCode, byte-identical; index
+  bump merged and published; bootstrap pin in #661.
+- The post-release fresh-install run (35154678676) installs the release on every
+  row. Its Homebrew leg on macOS 27 ran before the tap carried 2026.9.17.1 and
+  installed 2026.9.16.2, which failed at the std module exactly as §5.2 describes;
+  that leg is re-run against the bumped formula. The xlings leg on macOS 27
+  installs 2026.9.17.1 fresh, runs `mcpp new` then `mcpp run` (`Hello from
+  hello_mac!`), resolves a template package, and builds mcpp from source: the
+  released fix measured on the system it is for, with nothing wrapped.
+- No change was needed in mcpplibs/mcpp-index, mcpp-plugins or openxlings/xlings.
