Abstract
过去的房产销售行业模式存在许多弊端：一手新楼盘销售模式客源不足，网络投放广告引源效果差；采用“一二手房联动分销模式”，二手经纪公司过多难以管理；二手房市场同样存在信息化程度低，获取客源与房源成本高、效率低，网上二手房信息真实度低等问题。 行业模式的变革势在必行，房多多创世人段毅这样认为。在他构想中，房多多将是一个“能改变传统房地产销售价值链”的房地产营销平台。到2013年，房多多业务已经覆盖到全国10多个城市，提供专业的一二手联动业务线下与系统的同步服务，并进一步聚焦基于云端（SAAS）模式的互联网中介公司管理运营服务。但是，房多多要在激烈的同行平台竞争中脱颖而出，还面临着众多挑战：如何让中介公司快速感知房多多模式的价值所在？如何让中介公司放心分享房源和房客？如何提高云端模式的兼容性来实现快速扩张？

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
