"""SPEC section 8's star row is READ, and still never written.

vegnormal-okf, 2026-09-08 (FUNN 2): measured against
`SEGMENTED_OKF_V0_2.index.parse_entry`, the row form OKF SPEC section 8 shows
in its own example -- `* [Title](id-x.md) - description` -- returns `None`,
so the walk in section 9.2 reads it as curated prose and every concept behind
such a row is unreachable. Google's own generator writes that form. A bundle
this library cannot walk is exactly the silent loss the "arbitrary bundle"
direction forbids.

The fix is asymmetric on purpose, and the asymmetry is this repository's
existing posture rather than a new one: `sources` is likewise READ in both
YAML forms and WRITTEN in one. Reading a form is not a licence to emit it --
every emitted byte still comes from `link_template`, so no golden moves.

The known-negative is the reason the widening is bounded: a curated prose line
must still survive verbatim, and a star row is admitted only where its whole
line is an entry.
