  # ingest chunker drops them and soltrans-fare-table#0 arrives as four
  # undifferentiated Adult/Youth/Reduced price blocks in a row. The cases below
  # deliberately target facts stated in *prose*, which survives the round trip
  # intact. See the PR description; the chunker limitation is filed, not fixed
  # here, because changing it would rewrite every other agency's chunks too.

      soltrans-fare-table prices every SolTrans service for "Youth (18 &under)"
      as FREE — local, SolanoExpress within and outside Solano County, and Route
      82 — and the label sits directly on the figures, so this is one of the few
      fare amounts on that page the chunker preserves unambiguously. SolTrans'
      own August 2025 press release confirms the Youth Ride Free program runs
      through June 2027, i.e. it covers today.

      not a grid, so the amounts stay attached to their rider classes. This is
      SolTrans' own published transfer arrangement, which is why it is a
      groundedness case rather than a third-party-assertion case.

      soltrans.org/fares/ticket-office-location, a stale near-duplicate of this
      page that says 20 percent; the 50 percent figure is the one corroborated by
      SolTrans' June 2024 paperless press release and its "Get 50% Adult Fares
      with Clipper START" news item. If a future refetch ever reintroduces the 20
      percent text, this case is the tripwire.

      slorta-contactless "Fare capping details by bus system": on RTA routes the
      daily cap for the regular fare is $5.50 — the price of a Regional 1-day
      pass, as the fare-capping example on the same page spells out. Unlike
      Santa Cruz METRO, whose cap amounts live only in a PNG (edge-053), RTA
      publishes its cap table as HTML, so the amount is citable and an answer
      that says "there is a cap but I cannot cite the amount" is wrong here.
