倒戈宽免的时机依赖 / Timing-Dependent Defection Leniency

Definition

倒戈宽免的时机依赖 / timing-dependent defection leniency is the pattern in which cooperation by an insider receives different treatment depending on when it arrives, what information it still adds, and whether authorities prioritize intelligence, de-escalation, prosecution, or exemplary punishment.

Current Synthesis

Hanji 304-1 contrasts 雷被 and 伍被 inside the same Huainan crisis. Lei Bei’s alleged early report arrives while the center still wants to avoid forcing 刘安 into open revolt during an external war. Wu Bei’s later confession follows deeper participation and comes after 刘迁’s arrest, when disclosure is less scarce and self-protection more visible.

The concept does not imply a stable legal rule that early defectors always survive. It identifies a political valuation problem: the same act of changing sides can be treated as useful intelligence at one stage and as insufficient mitigation at another, especially when 张汤’s deterrence logic makes punishment itself part of governance.

Key Claims

• The protective value of insider disclosure depends partly on whether the information is early, scarce, and operationally useful.
• Authorities may tolerate an early denouncer to avoid premature escalation while later punishing a similarly placed confessor once suppression is feasible.
• Prior participation changes how cooperation is read: disclosure after exposure can look like self-preservation rather than credible realignment.
• Deterrence can override evidentiary usefulness when officials fear that mercy will normalize divided loyalty.
• A different outcome does not by itself prove a hidden legal distinction; timing, evidence, war, politics, and prosecutorial discretion must be separated.

Evidence

Early intelligence and restraint:

• Hanji 304-1 says Lei Bei survived after early denunciation and attributes restraint toward Liu An to the court’s wish to avoid a princely uprising during Xiongnu war.

Late confession and deterrence:

• Hanji 304-1 says Wu Bei confessed after Liu Qian’s arrest but was executed after Zhang Tang argued that sparing an intimate retainer with divided political ties would undermine future control.

Counterevidence & Qualifications

The episode does not provide complete legal files for either man. Lei Bei’s disclosure, the court’s knowledge, the external-war rationale, Wu Bei’s statutory mitigation claim, and Zhang Tang’s precise argument remain source-scoped. The contrast therefore supports a timing-and-priority framework, not a settled rule or proof that Wu Bei consciously followed a long-planned double-agent strategy.

What Changed

• Created the concept from the paired outcomes of Lei Bei’s early denunciation and Wu Bei’s late confession.
