The Q&A doc you're maintaining is fascinating you've essentially hand-built the thing I'm trying to automate. The 'Why Kafka?' entry is exactly the kind of decision that disappears when you leave. The search problem you raised is the core of what I'm solving — not dumping commits into a .md, but extracting structured decisions from the conversation that surrounded the commit: the Slack debate, the PR review, the ticket context. Then making it queryable by the code it relates to. You said you're not sure your process scales what happens to that Q&A doc if you leave tomorrow?
