Gotcha risk — resolution-rule assessment

The resolution rules clearly outline how the winning candidate and party affiliation are determined, including explicit provisions for independent or third-party candidates based on caucus intent. Resolution initially relies on a consensus of credible media reporting, with an official fallback to the Federal Election Commission if results remain ambiguous. California election counting typically requires several weeks to finalize, and resolution depends on the timing of calls across all House races, which introduces a moderate potential for delay.
