Sipmap team builds DejaView to recover rejected ideas and reasons from old open source discussions

At a Hacktoberfest Hack Day in Sonipat, a four-person team took on a problem asking for a system that reads past discussions and recovers the decisions made in them. They were inspired by the recurring loss of reasoning in open source projects, citing Python's rejected 'x as y' proposal as an example where the rationale lived only in a heated thread. Their tool, DejaView, reads a Python PEP discussion and returns the rejected ideas, why each failed, and the post where it was said. To work within the twelve-hour limit, the members divided the work by area and agreed on folder ownership and interfaces up front. Early on, they hit an API quirk where a thread request returned success with no posts, because the service uses separate global and human-visible post IDs.
