+## Note (2026-09-30): the outcome of an edit in the Note textarea, stated without its path
+
+A dated Note rather than an amendment: it carries no `Status:` line, decides
+nothing, and edits no line above it. It is added at the foot of the file, so
+no line another record cites moves. Every cite into `lib/` and `test/` below
+was read at `4a70851` and is written anchor first, line second.
+
+The Amendment of 2026-09-29 that adds clause `2s` says, under "The editor's
+field", that the editor turns the textarea's `note-change` event into one
+`{:update_note, id, note}` "through the same funnel as every other command"
+(`:13828-13829`). That phrase walks from the event to the command rather
+than stating what the edit produces. The Amendment stands as printed; this
+Note states the outcome the sentence is about (`sb-0suc`).
+
+- **One change is one `{:update_note, id, note}` command.** A change posted
+  from the Note textarea that moves the note commits that one command and
+  nothing beside it (`lib/statifier_blocks/editor.ex:1850`, `def
+  handle_event("note-change", ...)`); a posted note equal to the block's
+  current one commits nothing (the test "a change that moves nothing
+  commits nothing", `test/statifier_blocks/editor/note_field_test.exs:87`).
+- **One change is one undo entry.** A single undo after one change restores
+  the note the block held before, and a single redo puts the change back
+  (the test "a change applies the command, and undo and redo move the note",
+  `note_field_test.exs:66`).
