 The formatter works on the **token stream, not the AST**, so it preserves
 every line — comments and blanks included.  It normalises indentation, operand

 **Approach taken.**  Instead of parsing the compiler's iexport data (which
 would have required either `golang.org/x/tools` or an in-house parser), the
 resolver reads the **GOOBJ data directly** from the target package's `.a`
-archive.  The `.a` file contains a `_go_.o` member whose GOOBJ format is the
+archive.  The `.a` file contains a `_go_.o` member whose GOOBJ s is the
 same one gasm writes — the parser reuses the same layout (`blkSymdef`,
 `blkNonpkgdef`, the string table), so no new dependency was needed.
