/**
* Row "It understood" — how the question was routed to a skill, and whether the
* decided skill reached the model. Also check 1, `decided-delivered`.
*
* Two vouchers, two lines: the SCORES are the app's (its scorer produced them),
* the VERDICT is the library's (`skill.turn_routed`). Neither `decisive` nor
* `relevance` is a confidence — confidence stays "not recorded" in v1.
*
* "Not delivered" is a claim of ABSENCE, so it needs proof: every system-prompt
* composition of iterations 1..N is recorded and COMPLETE (the recorded skill
* rows of that compose stage number exactly `sourceBreakdown.skill.count`).
* Anything less and the check is unreachable — a missing row is never read as
* "the skill was not given".
*
* The verdict has ONE reader, {@link routingVerdictOf}: the `skill.turn_routed`
* event — or, on a RESUMED leg (whose recording holds that leg's events only),
* the verdict the RouteTurn stage committed before the pause: `turnRoute` (by,
* from, to, the rule's witness, the offered menu) and the scorer's
* `entryScores` / `entryScorer`, carried in the state the run paused with
* (`snapshot.initialState`) and on into the committed state the pointers land
* in. Take 3 of the demo video: a resumed answer said "The routing happened
* before the pause and is not in this record" while its record held the
* verdict — the fold read the event only. What the state does NOT carry is
* said by the lines that need it: the decider's model (the `noModel` line) and
* whether the verdict was decisive (absent from the fact).
