Who this is for: A solo dev or a small consultancy juggling multiple AI coding tools across multiple client projects, accountable for code quality and clean handoff.
The pain
You run Claude Code on one project, Codex on another, Antigravity on a third. Across attempts, you cannot prove what each tool changed, what tests passed, what the diff looked like, what you accepted. When a client asks "show me the trail", you reconstruct from chat logs and git blame.
The Codencer view
Every attempt becomes a run with structured artifacts. The diff, the test output, the validations — all recorded, all queryable, all replayable. The chat is no longer the source of truth. The run is.
