town op• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)
• Call: import fullseye as fs; fs.ledger.town_rules(jurisdiction: 'str' = 'JP') -> 'dict' (to call the implementation directly, import drivetown; drivetown.town_rules(jurisdiction: 'str' = 'JP') -> 'dict'; from the registry, opsdrive.get("town_rules"))
Rule pack (a copy of RULE_PACKS). {"jurisdiction", "side": "left"|"right", "crossing_stop": "always"|"when_active", "intersection_stop": "signal", "hold_s", "look_required", "look_hold_s", "sources": [...], "verified", "notes"}.
JP = left-hand traffic, always stop + safety check at railway crossings (Road Traffic Act (Japan) Article 33 Paragraph 1, confirmed in the text → verified True). US = right-hand traffic, ordinary vehicles stop only while the warning is active (state law. No primary confirmation → verified False). DE = right-hand traffic, under StVO §19 only while the barrier/lights are operating (no primary confirmation → verified False). Rules with verified False are not stated as definitive in PoCs or reports.
Raises ValueError: unknown jurisdiction.
