 ### 103. Fold `unspellable-whitespace` into `unsupported-node-shape`, so a line ending and a null character in a content slot take one code.
 
 `slotFault` in `directive-syntax.ts` gives a newline in an `emoji`, `mention` or `status` content
-slot `unspellable-whitespace` and a null character `unsupported-node-shape`, and the README gives
-both the same remedy. A consumer switching on `code` with no `default` keeps a case for one
-character class in one slot. 0.2.0 already removes the other `unspellable-*` codes; folding this
-one later is a break. Revise §Which code a cause takes, and add the change to the changelog's

+slot `unspellable-whitespace` and a null character `unsupported-node-shape`, though both take the

+`default` needs a case for a code only a line ending in these three slots raises. 0.2.0 already
+removes the other `unspellable-*` codes, so folding this one in now adds no new break; later it

 ### 84. Read GFM's pipe table without leading pipes, and with alignment colons, in `portableMarkdownToAdf`, dropping the alignment.
 
 Models write `|:---|` delimiter rows and tables without a leading pipe; both are
