**Own the Outer Loop. Evidence → Verdict → Answerability.**

Governance primitives for agentic engineering — any harness, any team size.

Companion to [loop-engineering](https://github.com/cobusgreyling/loop-engineering) (inner loops) and [harness-foundry](https://github.com/cobusgreyling/harness-foundry) (composable harness runtime). Works standalone with Cursor, Claude Code, or custom agents.

The loop in 60 seconds

Agent run  →  Evidence package  →  Human verdict  →  Ledger  →  Answerability
(inner)         (what happened)      (why ship/block)   (provenance)  (reconstruct why)

Humans define constraints and taste. Agents produce evidence. Humans issue verdicts with captured rationale. The system guarantees you can explain **why** something shipped.
