Changelog\_Entry // Game\_Agnostic\_Refactor

## Game-Agnostic Refactor & Protocol Hardening

The SDK core is now fully game-agnostic. RPG-specific concepts have been isolated into opt-in presets.

---

### Breaking Changes

* **`processNPCInput()`** no longer returns `Mood: neutral` in dialogue. It now summarizes arbitrary state keys. If you relied on the `mood` field in the response string, update your parsing.
* **`NPCState`** schema in the OpenAPI spec no longer defines `mood`, `inventory`, `skills`, or `relationships` as fixed fields. The state is now a fully open object (`additionalProperties: true`).

---

### What's New

* **Game-agnostic core** — `NPCState`, `MemoryType`, and `Mood` are all open types. No genre assumptions in `core/`, `npc.ts`, `soul.ts`, `memory.ts`, or `bridge.ts`.
* **RPG Preset rule collections** — `rpgRules`, `spatialRules`, `socialRules`, `puzzleRules` for mix-and-match validation.
* **Memory wired into Cortex prompt** — Relevant memories are now included in the local inference prompt, not just the API directive request.
* **Automatic memory storage** — NPC interactions are stored as `experience` type memories automatically.
* **`SDK_VERSION` export** — Version constant exported from the SDK, kept in sync with `package.json` via `npm run sync-version`.
* **Directive & Verdict endpoints** — `/npcs/{npcId}/directive` and `/npcs/{npcId}/verdict` added to the OpenAPI spec, matching the Haskell API implementation.
* **Haskell API fix** — `DirectiveRequest.dirMemories` now accepts structured memory objects `{text, type, importance}` instead of plain strings.

### SDK Test Coverage

Test infrastructure was rebuilt during this release cycle. The test plan comprises 32 BDD scenarios across 7 feature groups (NPC, Soul, Ghost, Memory, Bridge, Config, Architecture). See the [SDK status page](/npm/status) for current test coverage state.
