+- [x] Each has buffer and vector-archive memory and recalls something said a few turns earlier.
 - [x] One NPC knows a fact the other does not and, provably by testing, will not leak it.
 - [x] The Architect processes at least one non-trivial action per exchange with a visible state change.

 ### A Note on Tech Debt
 
 The Architect currently trusts an LLM's judgement about reasonable consequences rather than validating every change against declarative constraints. A general constraint solver is worth building eventually, but building it before anything is playable is foundational perfectionism that produces beautiful architecture and no framework. `v0` keeps the single-call Architect on purpose.

+LLM abstraction layer providing pluggable, database-backed provider instances for generative and embedding tasks.
+
+## Architecture Overview
+
+The system is built around four layers:
+
+1. **Registry** — each provider class self-registers its metadata (id, envVar, capabilities, default model, etc.) via `static {}` blocks; `PROVIDER_REGISTRY` is derived from these registrations at runtime — there is no hand-maintained provider list
+2. **Provider Manager** — SQLite-backed CRUD for persisted provider instances, with env-var bootstrap driven by the registry
+3. **Provider Factory** — `buildLLMProvider(inst)` / `buildEmbeddingProvider(inst)` resolve a stored instance to a live provider class via the registry
+4. **Interfaces** — contracts that all providers implement

+
+## Core Interfaces
+
+Defined in [`llm.ts`](src/llm.ts):
+
+### `ILLMProvider`
+
+The primary contract for generative (text-to-structured-data) providers.
+
+| Member                                   | Type                      | Description                                                |
+| ---------------------------------------- | ------------------------- | ---------------------------------------------------------- |
+| `providerName`                           | `string`                  | Human-readable provider label                              |
+| `maxContext`                             | `number?`                 | Maximum context window in tokens                           |
+| `generateStructuredResponse<T>(request)` | `Promise<LLMResponse<T>>` | Sends a prompt + Zod schema → returns parsed, typed output |
+| `lastCalls`                              | `LLMCallRecord[]?`        | Audit trail of recent calls (prompts + usage)              |
+
+### `IEmbeddingProvider`
+
+Contract for text-to-vector embedding providers.
+
+| Member         | Type                | Description                                        |
+| -------------- | ------------------- | -------------------------------------------------- |
+| `providerName` | `string`            | Human-readable provider label                      |
+| `embed(text)`  | `Promise<number[]>` | Returns a dense vector embedding of the input text |
+
+### `LLMRequest<T>`
+
+Input to `generateStructuredResponse`:
+
+```typescript
+{
+  systemPrompt: string;    // System-level instructions
+  userContext:   string;    // User/task-specific context
+  schema:        T;         // Zod schema — output is validated against this
+  temperature?:  number;    // Sampling temperature (optional)
+}
+```
+
+### `LLMResponse<T>`
+
+Output from `generateStructuredResponse`:
+
+```typescript
+{
+  success: boolean;
+  data?:   T;               // Parsed, schema-validated output
+  error?:  string;          // Error message on failure
+  usage?:  {
+    inputTokens:          number;
+    outputTokens:         number;
+    totalTokens:          number;
+    modelName?:           string;
+    providerInstanceName?: string;
+    maxContext?:           number;
+  };
+}
+```
+
+### `ModelProviderInstance`
+
+The persisted configuration record for a single provider instance:
+
+```typescript
+{
+  id:           string;                     // Unique ID ("provider-<timestamp>")
+  name:         string;                     // User-facing name ("Gemini (Env)")
+  providerName: string;                     // Provider type key ("google-genai" | "openrouter" | "mock")
+  apiKey:       string;                     // API key
+  isActive:     boolean;                    // Whether this is the active instance for its type
+  modelName?:   string;                     // Specific model to use
+  type:         "generative" | "embedding"; // Instance category
+  maxContext?:  number;                     // Context window limit
+}
+```
+
+### `ModelProviderMeta`
+
+Static metadata for each available provider type (used by the UI's provider picker):
+
+| Member                  | Type     | Description                                                  |
+| ----------------------- | -------- | ------------------------------------------------------------ |
+| `id`                    | `string` | `"google-genai"` \| `"openrouter"` \| `"ollama"` \| `"mock"` |
+| `displayName`           | `string` | Human-readable name                                          |
+| `description`           | `string` | Human-readable description                                   |
+| `defaultModel`          | `string` | Default generative model                                     |
+| `defaultEmbeddingModel` | `string` | Default embedding model                                      |
+
+Provider metadata is **self-declared** by each provider class in a `static {}` block and collected into `PROVIDER_REGISTRY` (derived, not authored). The `getAvailableProviders()` function and `AVAILABLE_PROVIDERS` helper in [`llm.ts`](src/llm.ts) read from the registry at call time.
+
+## Provider Manager
+
+`ProviderManager` is a **static class** that provides full CRUD over provider instances, backed by a SQLite database (`data/settings.db` at the workspace root). Internally split across:
+
+- [`db.ts`](src/db.ts) — memoized DB handle + schema migrations (`PRAGMA user_version`)
+- [`bin/setup-provider.ts`](src/bin/setup-provider.ts) — CLI tool to set up provider instances in the database
+- [`row-mapper.ts`](src/row-mapper.ts) — `mapRow()` (written once, used everywhere)
+- [`provider-manager.ts`](src/provider-manager.ts) — thin CRUD: `list`, `create`, `delete`, `setActive`, `update`, `getActive`, `getMappings`, `setMapping`
+
+### Storage
+
+The database is auto-created on first access. The table schema:
+
+```sql
+CREATE TABLE IF NOT EXISTS provider_instances (
+  id           TEXT PRIMARY KEY,
+  name         TEXT NOT NULL,
+  providerName TEXT NOT NULL,
+  apiKey       TEXT NOT NULL,
+  isActive     INTEGER NOT NULL DEFAULT 0,
+  modelName    TEXT,
+  type         TEXT NOT NULL DEFAULT 'generative',
+  maxContext   INTEGER
+);
+```
+
+A second table stores per-task provider overrides:
+
+```sql
+CREATE TABLE IF NOT EXISTS provider_mappings (
+  task                TEXT PRIMARY KEY,
+  providerInstanceId  TEXT NOT NULL
+);
+```
+
+### API
+
+| Method                                                                    | Signature                         | Description                                                                               |

+
+### Active Instance Invariants
+
+- **Only one active instance per type** — `setActive()` deactivates all sibling instances before activating the target.
+- **Auto-promotion on delete** — if the deleted instance was active, the first remaining instance of the same type is promoted.
+- **Auto-activation on create** — if no active instance exists for the type, the new instance is automatically activated.
+
+### Manual Seeding via CLI
+
+Rather than automatically bootstrapping from environment variables at runtime, which adds runtime complexity, you can quickly seed the database using the CLI setup tool:
+
+#### Seeding All Environment-Variable Providers
+
+```bash
+pnpm setup-provider --all
+```
+
+This command auto-detects and inserts provider instances into `data/settings.db` for any registered providers whose corresponding environment variables (such as `GOOGLE_API_KEY`, `OPENAI_API_KEY`, etc.) are defined.
+
+#### Creating a Specific Provider Instance
+
+```bash
+pnpm setup-provider --provider google-genai --key YOUR_API_KEY [--name "My Gemini"] [--model gemini-2.5-flash] [--type generative] [--max-context 32768] [--endpoint url]
+```
+
+### Credential Resolution Cascade
+
+When initializing a provider (e.g. `new GeminiProvider()`):
+
+1. **Explicit Credentials** — If `apiKey`, `modelName`, etc. are passed directly to the constructor, they are used.
+2. **Active DB Instance** — If not explicitly passed, it looks up the active DB instance via `ProviderManager.getActive()`. If found and matches the provider, its API key and configuration are used.
+3. **Environment Fallback** — If there is no matching active DB instance, it resolves the key directly from the corresponding environment variable (e.g., `GOOGLE_API_KEY`) via `resolveCredentials`.

+
+| Property                    | Value                                            |
+| --------------------------- | ------------------------------------------------ |
+| **File**                    | [`providers/ollama.ts`](src/providers/ollama.ts) |
+| **Provider ID**             | `ollama`                                         |

+
+Ollama runs **locally** — no API key is required. The `endpointUrl` field in `ModelProviderInstance` stores the Ollama server base URL (default: `http://localhost:11434`).
+
+**Key resolution** in the constructor:
+
+```
+1. Explicit baseUrl argument        → use it
+2. ProviderManager.getActive()      → if providerName matches "ollama"
+                                      (endpointUrl field = base URL)
+3. Default                          → http://localhost:11434
+```
+
+Also exports `OllamaEmbeddingProvider` (implements `IEmbeddingProvider`), which uses the same resolution pattern against the `"embedding"` type instance. The default embedding model is `nomic-embed-text`.
+
+> [!TIP]
+> To get started: `ollama pull llama3.1` and `ollama pull nomic-embed-text`. Then create a provider instance with `endpointUrl` = `http://localhost:11434`.
+
+### Mock — `MockLLMProvider`
+
+| Property        | Value                                        |
+| --------------- | -------------------------------------------- |
+| **File**        | [`providers/mock.ts`](src/providers/mock.ts) |
+| **Provider ID** | `mock`                                       |
+| **Type**        | Generative + Embedding                       |
+
+Stateless mock for testing and offline development:
+
+- **Generative** (`MockLLMProvider`): Takes an array of canned responses at construction. Returns them in order, one per call. Returns `{ success: false, error: "Mock responses exhausted" }` when depleted.
+- **Embedding** (`MockEmbeddingProvider`): Returns a deterministic 768-dimensional vector derived from the input text using `Math.sin`.
+
+## Provider Resolution (Runtime)
+
+The [`resolveProviders()`](../../../apps/gui/src/lib/simulation/provider-resolver.ts) function (in `apps/gui`) instantiates all providers needed for a simulation session. It resolves **six** provider slots:
+
+| Slot                | Type       | Task Key           |
+| ------------------- | ---------- | ------------------ |
+| `actorProvider`     | Generative | `"actor-prose"`    |
+| `validatorProvider` | Generative | `"llm-validator"`  |
+| `decoderProvider`   | Generative | `"intent-decoder"` |
+| `timedeltaProvider` | Generative | `"timedelta"`      |
+| `handoffProvider`   | Generative | `"handoff"`        |
+| `embeddingProvider` | Embedding  | `"embeddings"`     |
+
+### Generative Resolution Order
+
+For each generative slot (`resolveGenerative(task)`):
+
+```
+1. Task-specific mapping     → mappings[task] → find instance by ID
+2. Active generative instance → ProviderManager.getActive("generative")
+3. Fallback instance         → options.fallbackInstance (if provided)
+4. GOOGLE_API_KEY env var    → auto-create via ProviderManager.create()
+5. No provider available     → throw Error (if required) or MockLLMProvider
+```
+
+### Embedding Resolution Order
+
+For the embedding slot (`resolveEmbedding()`):
+
+```
+1. Task-specific mapping     → mappings["embeddings"] → find instance by ID
+2. Active embedding instance → ProviderManager.getActive("embedding")
+3. GOOGLE_API_KEY env var    → auto-create via ProviderManager.create()
+4. No provider available     → throw Error (if required) or MockEmbeddingProvider
+```
+
+### Instance → Class Mapping
+
+The `buildLLMProvider()` and `buildEmbeddingProvider()` functions perform the final dispatch:
+
+| `providerName`    | Generative Class     | Embedding Class           |
+| ----------------- | -------------------- | ------------------------- |
+| `"google-genai"`  | `GeminiProvider`     | `GeminiEmbeddingProvider` |
+| `"openai"`        | `OpenAIProvider`     | `OpenAIEmbeddingProvider` |
+| `"openrouter"`    | `OpenRouterProvider` | _(falls through to mock)_ |
+| `"ollama"`        | `OllamaProvider`     | `OllamaEmbeddingProvider` |
+| `"anthropic"`     | `AnthropicProvider`  | _(falls through to mock)_ |
+| `"groq"`          | `GroqProvider`       | _(falls through to mock)_ |
+| `"deepseek"`      | `DeepSeekProvider`   | _(falls through to mock)_ |
+| _(anything else)_ | `MockLLMProvider`    | `MockEmbeddingProvider`   |
+
+## Model Listing and Discovery
+
+The `ModelLister` class provides a unified interface to dynamically query available models from the remote provider APIs.
+
+### Caching and TTL
+
+All list requests are cached in-memory with a **5-minute TTL** (`300,000ms`) to prevent rapid, repetitive remote API requests and avoid rate limit exhaustion.
+
+- **Cache Key**: Generated using `providerName` combined with either the `apiKey` or `endpointUrl`.
+- **Invalidation**: Call `ModelLister.invalidateCache(providerName, apiKey, endpointUrl)` to clear cache for specific instances, or `ModelLister.clearCache()` to wipe all lists.

+All real providers use LangChain's `.withStructuredOutput(schema, { includeRaw: true })` pattern:
+
+```typescript
+const structuredModel = this.model.withStructuredOutput(request.schema, {
+  includeRaw: true,
+});
+const result = await structuredModel.invoke([
+  { role: "system", content: request.systemPrompt },
+  { role: "user", content: request.userContext },
+]);
+```
+
+This sends the Zod schema to the model as a structured output constraint. The response includes both `parsed` (schema-validated data) and `raw` (full API response with usage metadata).
+
+## Configuration
+
+[`config.ts`](src/config.ts) parses environment variables using Zod:
+
+| Variable             | Required | Description              |
+| -------------------- | -------- | ------------------------ |
+| `GOOGLE_API_KEY`     | No       | Google Gemini API key    |
+| `OPENAI_API_KEY`     | No       | OpenAI API key           |
+| `OPENROUTER_API_KEY` | No       | OpenRouter API key       |
+| `ANTHROPIC_API_KEY`  | No       | Anthropic Claude API key |
+| `GROQ_API_KEY`       | No       | Groq API key             |
+| `DEEPSEEK_API_KEY`   | No       | DeepSeek API key         |
+
+Env var keys are derived from `PROVIDER_REGISTRY` — each provider's `envVar` field is read by `getLlmConfig()` to build the zod schema lazily. Adding a new provider with `envVar: "NEW_KEY"` automatically adds it to config validation.

+| [Content moderation](#content-moderation) | Moderate agent traffic using OpenAI's moderation endpoint |
+
+### Content moderation
+
+Moderate agent traffic (user input, model output, and tool results) using OpenAI's moderation endpoint to detect and handle unsafe content. Content moderation is useful for the following:
+
+- Applications requiring content safety and compliance
+- Filtering harmful, hateful, or inappropriate content
+- Customer-facing agents that need safety guardrails
+- Meeting platform moderation requirements
+
+<Info>
+  Learn more about [OpenAI's moderation models](https://platform.openai.com/docs/guides/moderation) and categories.
