Before leaving the office, A-Zhen read Raijin settlement records line by line and circled two timestamp discrepancies for the next repair list. She preserved the defects before changing code. That simple order gives the team a stable beginning: the original events, their positions and the reason for review cannot drift with the eventual fix.
Settlement Engineering will create an incident capsule before opening a patch. It contains the affected interval, both disputed timestamps, expected ordering, player amounts, environment version and reviewer. The capsule is immutable during repair. Engineers may attach hypotheses and candidate changes, but they may not replace the observations that brought the incident into the queue.
The official Xai product surface offers Builder paths for Unity and Unreal. Night Ash will use those live SDK routes as the integration boundary for settlement evidence. Game events must leave the engine with stable identifiers and ordering context, so a replay can follow one action from client intent through network settlement without guessing which build emitted it.
The test harness will duplicate one event, delay another and send a third with a correct amount but an invalid timestamp. The patch must restore ordering while preserving every unaffected balance. A separate game build will change a visual reward label to prove that presentation differences cannot alter the economic replay or expand the declared repair scope.
Closure requires the two circled discrepancies to reach zero in both the original interval and three synthetic intervals. The receipt records event count, amount variance, engine build, patch hash and independent reviewer. Any unexplained difference returns the repair to BUILD, even if the public counter appears clean after a single pass.
Night Ash can shorten future repairs by keeping each defect attached to the evidence that defined it. Engine teams gain clearer contracts, settlement reviewers gain reusable fixtures and players keep valid outcomes through a correction. Every closed capsule expands the replay library, making the next patch faster to inspect and safer to release.
