Memory document has no closing frontmatter marker.

Error message

Memory document ${sourcePath} has no closing frontmatter marker.

What it means

parseMemoryDocument throws when a memory document has an opening --- frontmatter marker but no closing --- line, i.e. truncated or corrupted frontmatter. The faulting input is the document text at sourcePath; parsing cannot delimit the frontmatter block.

Solutions

1. Add the closing --- line after the frontmatter fields.
2. Restore the document from git or the memory backup if it was truncated.
3. Note CRLF and trailing-newline requirements: the closer must be preceded by a line break.
