@@ -196,6 +197,15 @@ at the code that implements it. `publish`'s `atomic` property says "every gate"
 "both gates" - it has three, and all run before staging. How a record's prose is written is now

+`index rebuild`, `log append` and `log status` rewritten the same way; text only. `log append`
+now lists its two exit-1 causes separately and states in NEVER what its retry policy said in
+prose: check the tail of `kb/log.md` before re-running after an uncertain outcome.
+`index rebuild`'s NOTES name the nested-page warning and what `--dry-run` prints, both of which
+the command already did. `log status` no longer claims it "reports 0" for a missing log - it
+reports that nothing is logged yet, which is what it always printed.
