> Study the at4tached files, which are the latest versions of our packages, along with 3 services using it and having used them for optiization. We want a simple, very clear, but compositionally very extendable / elegant (potentially through the use of interface graftpoints, for like plugins and such, keeping a small kernel that can be extended according to sound principles.

I’ll treat this as an architecture review, not just an API cleanup: first map the actual packages/services and their optimization usage, then separate essential semantics from accidental machinery, then propose a smaller compositional kernel with explicit graft points and migration options.

```unknown
bash -lc rm -rf /mnt/data/ragttc_unpack && mkdir -p /mnt/data/ragttc_unpack && unzip -q '/mnt/data/rag-ttc(4).zip' -d /mnt/data/ragttc_unpack && find /mnt/data/ragttc_unpack -maxdepth 3 -type f | sed 's#^/mnt/data/ragttc_unpack/##' | head -300
```

One important pattern is already visible: `ragkit` is an extraction of mechanisms from `rag-ttc`, while `ragopt` evolved separately as an experiment-control/custody system. I’m checking whether their abstractions align naturally or whether they currently force two overlapping notions of “identity, run, evidence, and policy.”

```unknown
bash -lc cd /mnt/data/ragttc_unpack && for f in ragkit/README.md ragopt/README.md rag-ttc/README.md code/gec/2026-03-16--gec-rag/README.md 2026-05-27--ttc-design-system/backend/go.mod rag-ttc/go.mod code/gec/2026-03-16--gec-rag/go.mod; do echo '===== '$f; sed -n '1,220p' "$f"; done
```

**Designing the kernel**

I’m evaluating whether to extract a small shared kernel rather than rewrite everything. The likely core includes typed operations, candidate collections, deterministic views, effect handling, provenance, and explicit extension points.

**Designed the kernel**

**Inspected RAGKit architecture, services, flows, modules, metrics, and optimization contracts**

</details>

The likely simplification is not “merge ragkit and ragopt.” Their domain roles are correctly different. The promising move is to give both a **shared tiny algebraic substrate**—identity, immutable values, effect requests/observations, lawful accumulation, and deterministic projections—then let RAG and optimization be separate extensions over it.

```unknown
bash -lc cd /mnt/data/ragttc_unpack && echo 'ragopt digest/write primitives'; sed -n '1,260p' ragopt/pkg/candidate/digest.go; sed -n '1,300p' ragopt/pkg/runstore/write.go; sed -n '1,280p' ragopt/pkg/runstore/types.go; echo '\nragkit digest/cache primitives'; sed -n '1,240p' ragkit/digest/digest.go; sed -n '1,300p' ragkit/execution/cache.go
