yasuki_core.install.format_metadata.populate_format_metadata#

populate_format_metadata(cur)[source]#

Fill formats.arc / block / legal_from from FORMAT_METADATA and the loaded set release dates.

legal_from is the earliest release_date among the arc’s sets (NULL for non-arc formats), so the chronology stays sourced from set metadata rather than hardcoded here. Idempotent: re-running refreshes the three columns. Requires l5r_sets to be populated first.
