公孙范 / Gongsun Fan (late Han)
公孙范 / Gongsun Fan (late Han) enters the wiki through Hanji 958 as 公孙瓒’s kinsman and the recipient of 袁绍’s attempted concession. After Gongsun Zan blames Yuan Shao for 公孙越’s death and moves into open pressure, Yuan Shao gives Gongsun Fan the 渤海郡 office as a signal of retreat or appeasement.
The move backfires. The source says Gongsun Fan takes the Bohai troops and defects to Gongsun Zan, converting Yuan Shao’s concession into enemy strength. His role therefore makes 利益结构式联盟脆弱性 concrete: a placating office can become a force-transfer mechanism when kinship and rivalry make the recipient’s incentives different from the grantor’s.
