I've been using Claude Code heavily for the past year, and I kept running into the same wall: an agent would make a schema change, rename a function, or add a dependency, and six weeks later I had no idea why. `git blame` tells me what changed and when. It doesn't tell me why. The original prompt that drove the decision evaporated the moment the session ended.

Selvedge is an MCP server that fixes this. AI agents call it as they work to log structured change events, including the reasoning behind each decision. It stores everything locally in SQLite.
