Zed's DeltaDB records every edit between commits and links it to the agent conversation that caused it.

Announced August 5, topping HN at 455 points and 241 comments. Each operation between commits gets a stable identity tied to its originating agent conversation, the worktree is virtualized so spinning up a new agent branch is "effectively free," and teammates can join work in progress without commit/push gates. Zed has published no architecture, language, licensing or performance detail, and it's email-gated early access. So this is positioning, not something you can evaluate. But "commits are the wrong granularity for agent work" is the right problem statement, and nobody else has said it this clearly.
