//! Pi V12 incremental tests: repeat deduplication, appended reads, partial lines,

//! truncation/equal-size replacement/rename detection, bounded resumption and conflicting duplicates.

//! Scenarios follow codex_incremental_v12.rs; base data is real and redacted:

//! session-error-zero-usage has seven lines, with the only event on L7.

/// Reconstructed native session path relative to sessions/<encoded-cwd>/<file>.

// Write six lines without usage, then append the seventh assistant line.

// Appended reads retain session identity through persisted parser context and cursor.

// Write complete earlier lines and half the final assistant line.

// Complete the last partial line.

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

// Stored history survives source truncation.

// Swap two complete JSON lines without changing byte length or the initial session header;

// changed content fingerprints must cause a rescan.

// Identical key/content on rescan leaves one event without double counting.

// Manual synthetic-auxiliary-carriers values: eight lines/six events ordered as session/model_change/

// assistant with usage/assistant without usage/usage/compaction/branch_summary/toolResult.

// Batch line limits 3+4+100 produce events 1+4+1; total calls=6 and input_total=2915,

// cache_read=1190, cache_write=110, output=355, total=3270.

// Copy synthetic data to the temporary test directory, preserving repository data.

// syn-cf-1 initially has input=1000/cacheRead=400, giving input_total=1400 and total=1450.

// Same identity tuple with input=1500 has no ordered revision: mark conflict and retain stored values.

// Append the same type/id/parentId/timestamp tuple with different usage.

// Retain input_total=1400 rather than choosing the larger value; mark conflict and diagnose.
