Before dawn at the Hexing Branch of the Bureau of Bound Confessions. The black-glass tower looms over empty streets while one workroom lamp remains lit.

Wenruo reviews what the Bureau's blood contract allows and forbids before choosing her method.

In the receipt gallery, Wenruo creates the first controlled offense.

Wenruo confesses the misfiled receipt to an ordinary clerk to obtain a receiving signature and stamp sample.

Wenruo creates the second minor offense, then approaches Han Yuli's junior desk.

Han processes Wenruo's confession, flattered and nervous to handle a superior auditor's minor violation.

Wenruo compares Han's fresh sample against old ledger strokes and turns the confession into data.

Wenruo creates the third controlled offense at the edge of a restricted archive line.

A corridor clerk challenges Wenruo, giving her a lawful reason to request medical counterseal review.

Doctor Lin Su examines the harmless threshold violation and adds the counterseal Wenruo needs for comparison.

Wenruo collects the three fresh confession samples while the Bureau's pre-dawn bells approach.

Wenruo builds a handwriting key from the fresh samples.

Wenruo's investigation visually plunges into layered historical records without becoming a disconnected montage.

Wenruo identifies how junior auditors became disposable carriers in the confession chain.

Wenruo matches fresh handwriting samples to historical entries and separates innocent clerks from ordered patterns.

The historical chain leads to Li Yan's old auditor pages.

Li Yan's old pages show delayed stamps and objections hidden as margin law.

Li Yan's final refusal appears in the ledger record, followed by a sudden gap.

Wenruo finds her own handwriting replacing Li Yan's in the manufactured-sin chain.

The records connect the substitution chain to Cao's receiving authority through stamps and title codes, not an on-page confrontation.

Wenruo races dawn to preserve the discovered chain in her pocket ledger.

As sunlight reaches the clerks' hall, the small confessed offenses begin vanishing from Wenruo's memory.

Wenruo finds proof that she has run this exact experiment before.
