# Populate journal/chronicle/ with media from a local clone of
# github.com/solpbc/field_journal — a public-domain corpus for dev/test runs.
#
# Opt-in dev primitive. Not part of the canonical install/setup paths; run only
# when you want a contributor/integration-test journal seeded from public media
# rather than personal capture data. Full guide: docs/FIELD_JOURNAL.md.
#
# Usage:
#   ./setup_field_journal.sh [--source PATH] [--force]
#
# Options:
#   --source PATH  Path to the field_journal clone. Default: ~/Field_Journal
#   --force        Overwrite existing chronicle days
#   -h, --help     Show this help
#
# The script copies (does not symlink) each YYYYMMDD day directory from
# <source>/journal/ into ./journal/chronicle/. Copying is intentional: solstone
# writes derived artifacts (audio.jsonl, audio.npz, descriptions, etc.) as
# siblings of source media, so symlinking would dirty the field_journal clone.
#
# Run `journal setup` afterward to bring the journal to a ready-to-process state.
