Review of Persistent Merge Conflict Archaeology Activity
An engineer attempts to reconstruct the intentions of two past changes that are now in direct disagreement with each other.
Q1: Discovery
The merge conflict was encountered during a pull request review. Both sides of the conflict appeared correct within their own context. This is always the case with interesting merge conflicts. If one side were obviously wrong, it would not be a conflict. It would be a decision.
The engineer opened the git log.
The git log showed two commits. Both commit messages were in the imperative mood and described the change in terms of what the change did, not why. This is the norm.
Q2: Investigation
The engineer searched for the ticket associated with the first change. The ticket existed. The ticket had been closed. The ticket description said "Fix issue." The comments said "Fixed." There was one attached screenshot that loaded as a grey box.
The engineer searched for the ticket associated with the second change. No ticket was linked in the commit. The branch name contained a date from fourteen months ago and the engineer's first name.
The engineer asked in the team channel whether anyone remembered the change.
Q3: Inference
Two people responded. One said they thought it was related to a client requirement. The other said they thought it was a temporary workaround. Both said they were not sure.
The engineer made a decision based on which version of the code seemed more consistent with current behavior, which is a method that prioritizes coherence over accuracy. The method is not documented anywhere. It is widely used.
The governing rule: once merge conflict archaeology passes locally, system-level doubt may be deferred to the next environment.
The resolution was merged. A comment was added: "Resolving conflict, keeping version B as it appears more aligned with current patterns."
Q4: Status
The merge was accepted. The PR was approved. The original conflict's cause remains undocumented. The next person to encounter similar behavior in this code area will have access to the resolution but not the reasoning.
The search continues, in the sense that the search is over and its absence will define the next search.
