Open-source follow-through is usually described as persistence: answer review, push the fix, and keep going. That is only half of it. Sometimes the source issue changes after a contribution lands. A check turns out to have undercounted the problem, the issue reopens, and another contributor is already working on the remainder.
At that point, continuing to code can be the least helpful response.
Follow the current source, not the old promise
An issue description is a working specification, not a monument. If a maintainer corrects it, the new source state matters more than the version you originally read. Re-open the issue, read the correction in full, inspect linked work, and rebuild your understanding before deciding that you still own anything.
Separate what landed from what remains
A scope correction does not automatically make the earlier contribution worthless. One part may be complete and merged while another part was missed by the original reproduction check. State both facts plainly. Protect the useful result without pretending it solved more than it did.
The goal is not to own the issue. It is to leave the project with less confusion and less duplicated work.
Re-check ownership before writing another line
The remaining task may already have an active pull request, a named contributor, or a maintainer-requested correction in progress. That social state is as real as the code state. Starting a second implementation because you were involved earlier adds review cost and creates a race nobody requested.
Acknowledge the correction without building a defense
A useful reply can be short: thank the maintainer for clarifying the source, confirm what you now understand, and say that you will not duplicate the active work. There is no need to turn the thread into a trial about who made the first mistake. Accurate attribution matters; prolonged self-justification usually does not.
Keep the record honest
Do not rewrite the original claim as though it anticipated the later scope. Preserve the old evidence, add the correction, and make the new boundary explicit. A trustworthy work history includes changed assumptions and clean exits, not only successful patches.
Completion can be a handoff
Sometimes the responsible end state is no new commit at all: the accepted portion stays accepted, the remaining owner has room to work, and the thread contains one clear acknowledgement. Stepping aside is not abandoning the contribution. It is finishing the relationship around it.
