-3. Populate "description" and "selfDescription":
-   - "description": No subject or name — a bare third-person verb phrase only (e.g. "clears their throat", "shakes their head slowly")
-   - "selfDescription": The same event from the actor's own perspective, second person, complete sentence starting with "You" (e.g. "You clear your throat.", "You shake your head slowly."). This is shown directly in the actor's own memory — it must never say "the actor" or refer to them in the third person.
-   - In case of a dialogue, the description and self Description only stores the exact words said by the entity. (e.g. "I will do that later", "Are you serious right now?")
-4. Identify targetIds — the entity IDs of the receiving parties. Use the "KNOWN ENTITY IDS" mapping to resolve any subjective names,or aliases used in the prose to their correct system entity IDs. If no specific target, use an empty array.
-5. Identify modifiers — a list of strings representing additional qualities or modifiers extracted from the narrative prose. This includes emotions, tone of voice, speed, manner of action, or statement type (e.g., "question", "anxious", "whispering", "slowly", "quietly", "forcefully").

+
+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                                                                               |
+| ------------------------------------------------------------------------- | --------------------------------- | ----------------------------------------------------------------------------------------- |
+| `list()`                                                                  | `→ ModelProviderInstance[]`       | Returns all saved instances                                                               |
+| `create(name, providerName, apiKey, modelName?, type?, maxContext?)`      | `→ ModelProviderInstance`         | Creates a new instance. Auto-activates if it's the first of its type                      |
+| `delete(id)`                                                              | `→ void`                          | Removes an instance. If it was active, auto-promotes the next instance of the same type   |
+| `setActive(id)`                                                           | `→ void`                          | Deactivates all instances of the same type, then activates the target                     |
+| `update(id, name, providerName, apiKey?, modelName?, type?, maxContext?)` | `→ void`                          | Updates an existing instance. If `apiKey` is empty/omitted, the existing key is preserved |
+| `getActive(type?)`                                                        | `→ ModelProviderInstance \| null` | Returns the currently active instance for the given type (`"generative"` by default)      |
+| `getMappings()`                                                           | `→ Record<string, string>`        | Returns all task → providerInstanceId mappings                                            |
+| `setMapping(task, providerInstanceId)`                                    | `→ void`                          | Sets or removes (if `providerInstanceId` is empty) a task-specific mapping                |
+
+### 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`.
+

+
+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.
+
+### Provider Integration Details
+
+| Provider          | Endpoint                     | Auth Header             | Pagination                  |
+| ----------------- | ---------------------------- | ----------------------- | --------------------------- |
+| **Google Gemini** | `GET /v1beta/models?key=KEY` | Query Param             | ✅ Loop via `nextPageToken` |
+| **OpenAI**        | `GET /v1/models`             | `Authorization: Bearer` | ❌                          |
+| **Anthropic**     | `GET /v1/models`             | `x-api-key`             | ✅ Loop via `after_id`      |
+| **Groq**          | `GET /openai/v1/models`      | `Authorization: Bearer` | ❌                          |
+| **DeepSeek**      | `GET /models`                | `Authorization: Bearer` | ❌                          |
+| **Ollama**        | `GET /api/tags`              | None (Local)            | ❌                          |
+| **OpenRouter**    | `GET /api/v1/models`         | Optional Bearer         | ❌                          |
+| **Mock**          | Instant return (no fetch)    | —                       | —                           |
+
+### Methods
+
+- `listModels(providerName: string, apiKey: string, endpointUrl?: string): Promise<ModelInfo[]>`
+- `invalidateCache(providerName: string, apiKey: string, endpointUrl?: string): void`
+- `clearCache(): void`
+
+---
+
+## Structured Output
+
+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.
