The flattener's last-resort branch rewrote ASCII ' to U+2019, justified as the
one combination no YAML scalar can carry verbatim. That claim was false: a |-
literal block with a single indented content line carries ', ", \ and ": "
verbatim and keeps text.frontmatter.description matching — as the wrapper's own
docstring already said of literal blocks. The rewrite fired on 12 of 54
in-scope files, silently disabling every rule whose token contains an
apostrophe. Case 20 pinned only that the scope stayed alive, so it passed
either way.
The emission site now splits the emitted scalar on its first newline so a
carried-over trailing comment stays on the "description: |-" header line rather
than becoming part of the value, and pads by span_lines - 1 - newlines. The pad
stays non-negative because the branch is only reachable when the original span
is at least two lines. Verified across all 73 in-scope files: no line-count
changes, and exactly the 12 expected files take the new branch.
One reported position moves: an alert on a description that is itself flagged
shifts from the key line to the block's content line, both inside the original
span. YAML cannot put a literal block's content on the key's own line, so this
is unavoidable; no line at or after the end of any description span moves.
Also: --output no longer absolutises the built-in style names line, JSON and
CLI, which a same-named file or directory in cwd turned into a template path
(exit 2, E100 Runtime error). And case 19's empty-baseline guard no longer
lets five dependent comparisons print vacuous passes — while fixing it the
guard turned out to be unreachable, since under pipefail an alert-free report
aborted the script at the assignment.
