Problem

go.mod includes sonic, msgpack, cbor, jsoniter, pgx, nats, sqlite all in core. A user who wants just MemoryStore for testing pulls in NATS, Postgres, sonic, msgpack.

Fix

Split into sub-modules:

eskit (core) — Event, Decider, Reactor, Projection, MemoryStore, Codec interface. Zero external deps.
eskit/sqlitestore — SQLite store (depends on modernc.org/sqlite)
eskit/pgstore — Postgres store (depends on pgx)
eskit/natsstore — NATS store (depends on nats.go)
eskit/codec — CBOR, jsoniter, msgpack, sonic codecs (each optional)
eskit/otelkit — already separate ✅

Acceptance

Core go.mod has minimal deps (go-cmp for testing only)
Each store is independently importable
Users only pull what they use
No breaking import path changes (use Go workspace or multi-module repo)

## Problem go.mod includes sonic, msgpack, cbor, jsoniter, pgx, nats, sqlite all in core. A user who wants just MemoryStore for testing pulls in NATS, Postgres, sonic, msgpack. ## Fix Split into sub-modules: - `eskit` (core) — Event, Decider, Reactor, Projection, MemoryStore, Codec interface. Zero external deps. - `eskit/sqlitestore` — SQLite store (depends on modernc.org/sqlite) - `eskit/pgstore` — Postgres store (depends on pgx) - `eskit/natsstore` — NATS store (depends on nats.go) - `eskit/codec` — CBOR, jsoniter, msgpack, sonic codecs (each optional) - `eskit/otelkit` — already separate ✅ ## Acceptance - [ ] Core go.mod has minimal deps (go-cmp for testing only) - [ ] Each store is independently importable - [ ] Users only pull what they use - [ ] No breaking import path changes (use Go workspace or multi-module repo)
