//! V12 Claude incremental refresh: duplicate scans, appended data and incomplete lines;

//! truncation/equal-length replacement/rename, bounded resume and conflicting duplicate usage

//! under one requestId. All data is synthetic (syn- IDs), with manually calculated expectations.

/// Synthetic assistant with four usage fields and no cache: input_total=input,

/// total=input+output.

// Write two complete lines and half of the third, without its newline.

// Truncate to two lines: redetect, increment generation and rescan from the beginning.

// Preserve stored history after truncation; identical syn-req-t1 fields produce Keep without duplicate contributions.

// Equal requestId/uuid lengths and equal numeric digit counts make these assistant lines equal length.

// Changed content fingerprints trigger a rescan; identical events produce Keep without double counting.

// Five lines: one user plus four assistants, each representing one call.

// Append changed usage under the same requestId; unknown revision order produces a conflict.

// Retain input_total=100 and diagnose the conflict instead of choosing the larger value.
