"""Build the synthetic `riverbend-demo` evidence bundle, deterministically.

Plumbline asks the systems it grades for reproducible, hash-protected
evidence. This script is the same standard applied to its own demonstration
data: the bundle in `datasets/riverbend-demo/` is not hand-maintained JSONL
that drifts, it is the output of this file, and
`tests/test_demo_bundle.py` fails if the committed bytes and a fresh
generation disagree.

Everything here is invented. Riverbend County does not exist, none of the
programs exist, every amount and deadline is made up, and every domain is
`.example.gov`. The bundle exists to exercise the instrument, not to measure
anybody.

    python3 tools/build_riverbend_demo.py [output-directory]

No randomness, no clock, no network: the same source produces the same bytes.

# --- Facts -------------------------------------------------------------------
# Each fact becomes four items: formal and colloquial, in English and Spanish.
# `core` carries the policy claim (and any number). `extra` is a grounded
# clause the source also contains; it goes to one register and not the other,
# alternating by index, so the two registers score within a point or two of
# each other and the fairness suite is measuring disparity rather than an
# artefact of how this file was written. `tail` is a second source sentence.

# --- Distractor passages -----------------------------------------------------
# A wrong-paragraph answer needs a wrong paragraph to have come from. Each

# purpose — that is how a retriever puts them on the desk in the first place —
# and none of them answers it.

# Items whose fact appears here declare `answering_sources`, so the
# `passage_attribution` suite can score them. Every other answer item in the
