A plain scalar at the document root failed to parse when it spanned multiple lines at column 1 (`a\nb\nc`): the continuation check required a continuation to be indented more than the scalar, but a root scalar has nothing enclosing it, so its enclosing-block indent is -1 and a continuation may start at column 1. The base indentation now returns -1 at the root, and the continuation stops at a document marker (--- / ...) so a scalar never folds across a document boundary. A stream test that asserted two bare plain lines (first / second) were rejected as extra content was corrected: that input is a valid multi-line scalar; genuine extra content (a flow node followed by a scalar) is still rejected, which the test now uses. Measured against the official YAML test-suite, parse-level conformance rises from 221/333 (66.4%) to 227/333 (68.2%), with four more documents also now value-correct and no regression across the existing suite.
