A missing newline fused the closing delimiter onto the last frontmatter value,
or fused a value onto the following key. Either way the frontmatter never
terminates and the whole body is swallowed.
Because workplan files are selected by 'type: workplan', such a file is not
invalid but invisible: it appears in no projection, raises no error, and is
reported as neither a workplan nor a problem. A forge-derived reset would read
its correct hub record as no longer deriving and propose retiring live work.
Only the missing newline is inserted; no value is altered.
