Arbitrary-sequence forks place the inherited end-seed marker before their
synthetic tool, step and turn closers. The Session constructor receives that
whole prepared seed, so firstLiveSeq can follow the inherited marker and the
constructor is no longer its sole producer. The retained documentation still
claimed both facts and could lead a consumer to use the wrong ownership cut.
Name buildForkSeed and the constructor as the two core producers, distinguish
the inherited cut from ordinary restore markers, and retain the warning about
plugins appending their own markers. Correct the subsystem reference's claim
that interrupted is the only synthetic turn ending: forked is also never
emitted by a live loop. Keep the bilingual reference and type-equivalent
excerpts aligned with the source JSDoc.
Refresh the required persistence catalog after the JSDoc change. Its schema
inventory changes only three source-line locations; all 61 roots, 472 types
and fingerprints remain identical. Parsed TypeScript declarations printed
without comments are also identical, so this changes neither runtime behavior
nor persisted fields, historical generations or recorded Session fixtures.
