Comment 1, line 1

//! V12 incremental refresh: repeat scans, appended lines, incomplete lines across runs, truncation,

//! same-size replacement, rename detection, bounded scan resumption and conflicting duplicate finals.

// Write ten lines without usage, then append the remaining seven.

// Write every complete line except the last, plus the first half of that last line.

// Complete the final task_complete line.

// Truncate to ten lines: redetect, increment generation and rescan from the start.

// Retain stored history after truncation; the remaining ten lines contain no usage events.

// Same-size replacement swaps two complete valid JSON records with a supported cli_version,

// changing the content fingerprint and requiring a rescan.

// Reordered lines change the fingerprint; the supported format is rescanned line by line.

// Retain original session history while parsing the replacement content independently.

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

// Append a final with the same response_id and different values; unknown revision order means conflict.

// Do not choose the larger value: retain 1000 and record the conflict diagnostic.
