+# Memory "Remember" Triggers - Implementation Plan
+
+## Overview
+
+This document outlines the implementation of "remember" triggers for the memory system. Currently, we have recall (search) working for volatile and documents, but no automated triggers to populate these memory tiers.
+
+**Key architectural principle:**
+- **Scheduler-driven**: Prefetch data that's useful on a repeating schedule (weather, news)
+- **HybridRAG-driven**: Cache ad-hoc ephemeral data discovered during searches
+- **Learning loop**: HybridRAG can register scheduler tasks when it discovers prefetch-worthy patterns
+
+---
+
+## Current State
+
+| Memory Tier | Remember Trigger | Recall | Status |
+|-------------|------------------|--------|--------|
+| Wiki | Wiki.js webhook, Consolidation | HybridRAG vector+graph | ✅ Complete |
+| Documents | Paperless webhook | HybridRAG document search | ✅ Complete (v1.6.0) |
+| Volatile | Scheduler prefetch, HybridRAG post-processor | HybridRAG volatile search | ✅ Complete (v1.6.0) |
+
+### Implementation Summary (v1.6.0)
+
+- **Settings DB**: Central `system_settings` PostgreSQL database with `SettingsClient`
+- **Phase A**: Volatile fetch endpoints (`/volatile/fetch/{namespace}/{key}`) with weather, news, financial providers
+- **Phase B**: Unified memory routing in consolidation service (wiki/volatile/file/prefetch/skip classification)
+- **Phase C**: Document recall in HybridRAG (4-source parallel retrieval)
+- **Scheduler Integration**: `SchedulerClient` for external scheduler task registration
+
+---
+

+## Central Settings Database
+
+### Rationale
+
+External API credentials (NewsAPI, etc.) and configs (Open-Meteo) should NOT be in environment variables because:
+- They're not deployment-specific (same across all environments)
+- They change independently of deployments
+- Multiple services across Tatlock need access to shared credentials
+- Environment variables require container restarts to update
+
+### Database Choice: PostgreSQL
+
+**Decision:** Use `postgres-shared` container (existing Tatlock infrastructure).
+
+Create a new database `system_settings` on the shared PostgreSQL instance. This container exists specifically for cross-service databases.
+
+### Schema Design
+
+```sql
+-- Run on postgres-shared as admin user
+
+-- Create database
+CREATE DATABASE system_settings;
+
+-- Create settings user (shared across all Tatlock services)
+CREATE USER settings WITH PASSWORD 'changeme';
+GRANT ALL PRIVILEGES ON DATABASE system_settings TO settings;
+
+-- Connect to system_settings database
+\c system_settings
+
+-- Create table
+CREATE TABLE settings (
+    key VARCHAR(255) NOT NULL,
+    user_scope VARCHAR(100) NOT NULL DEFAULT 'global',  -- 'global' or specific username
+    value JSONB NOT NULL,
+    schema JSONB,              -- JSON Schema for UI rendering (nullable)
+    description TEXT,
+    updated_at TIMESTAMP DEFAULT NOW(),
+    updated_by VARCHAR(100),
+    PRIMARY KEY (key, user_scope)
+);
+
+-- Index for user-scoped lookups
+CREATE INDEX idx_settings_user_scope ON settings(user_scope);
+
+-- Grant full access
+GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO settings;
+```
+
+### Query Pattern
+
+```sql
+-- Get setting with user override, fallback to global
+SELECT value, schema FROM settings
+WHERE key = $1 AND user_scope IN ($2, 'global')
+ORDER BY CASE WHEN user_scope = $2 THEN 0 ELSE 1 END
+LIMIT 1;
+```
+
+### Data Types with JSON Schema
+
+The `schema` column contains JSON Schema for UI widget rendering:
+
+| JSON Schema | UI Widget |
+|-------------|-----------|
+| `{"type": "string", "format": "password"}` | Masked input |
+| `{"type": "string", "enum": [...]}` | Dropdown/select |
+| `{"type": "boolean"}` | Toggle switch |
+| `{"type": "array", "items": {"type": "string"}}` | Multi-select or list |
+| `{"type": "number", "minimum": 0, "maximum": 100}` | Slider or number input |
+| No schema | Raw JSON editor |
+
+### Example Data
+
+```sql
+-- Global API keys (with schemas for CRUD UI)
+INSERT INTO settings (key, user_scope, value, schema, description) VALUES
+('api.openmeteo', 'global',
+ '{"base_url": "https://api.open-meteo.com/v1/forecast", "timezone": "Europe/Amsterdam"}',
+ '{
+   "type": "object",
+   "properties": {
+     "base_url": {"type": "string", "format": "uri", "title": "Base URL"},
+     "timezone": {"type": "string", "title": "Default Timezone"}
+   }
+ }',
+ 'Open-Meteo weather API (no API key required)'),
+
+('api.newsapi', 'global',
+ '{"api_key": "xxx"}',
+ '{
+   "type": "object",
+   "properties": {
+     "api_key": {"type": "string", "format": "password", "title": "API Key"}
+   },
+   "required": ["api_key"]
+ }',
+ 'NewsAPI.org credentials'),
+
+('api.nos_rss', 'global',
+ '{"feed_url": "https://feeds.nos.nl/nosnieuwsalgemeen"}',
+ '{
+   "type": "object",
+   "properties": {
+     "feed_url": {"type": "string", "format": "uri", "title": "Feed URL"}
+   }
+ }',
+ 'NOS.nl RSS feed');
+
+-- User-specific preferences (explicit choices)
+INSERT INTO settings (key, user_scope, value, schema, description) VALUES
+('weather.units', 'jpmschweitzer',
+ '"metric"',
+ '{"type": "string", "enum": ["metric", "imperial"], "title": "Temperature Units"}',
+ 'Preferred temperature units'),
+
+('news.sources', 'jpmschweitzer',
+ '["nos", "reuters"]',
+ '{
+   "type": "array",
+   "items": {"type": "string"},
+   "uniqueItems": true,
+   "title": "News Sources"
+ }',
+ 'Preferred news sources');
+```
+
+### What Goes Where
+
+| Data Type | Storage | Examples |
+|-----------|---------|----------|
+| **API credentials/config** | Settings DB (global) | `api.openmeteo`, `api.nos`, `api.alphavantage` |
+| **Explicit user preferences** | Settings DB (user-scoped) | `weather.units`, `news.sources` |
+| **Learned user facts** | Biographer knowledge graph | Location, interests, schedule |
+| **Internal service URLs** | ENV vars | `SCHEDULER_URL`, `REDIS_HOST` |
+
+**Key principle:** Settings DB stores explicit choices. Biographer stores learned context.
+
+**Example flow for weather fetch:**
+1. Scheduler triggers `/volatile/fetch/weather`
+2. Fetch service queries biographer: "Where does this user live?"
+3. Biographer returns "Rotterdam" from knowledge graph
+4. Fetch service reads `weather.units` preference from settings
+5. Calls Open-Meteo API (geocode city → lat/long → forecast) with units from settings
+6. Stores result in volatile cache
+
+### Library-Desk Integration
+
+**ENV vars (deployment-specific only):**
+```bash
+# Central settings database
+SYSTEM_SETTINGS_HOST=postgres-shared
+SYSTEM_SETTINGS_PORT=5432
+SYSTEM_SETTINGS_DB=system_settings

+
+### B.4 Scheduler Client
+
+**New file:** `src/clients/scheduler_client.py`

+
+### B.5 Config Options
+
+**Modify:** `src/models/hybrid_rag.py`
+
+```python
+class HybridRAGConfig(BaseModel):
+    # ... existing fields ...
+
+    # Memory auto-save options
+    save_documents: bool = Field(default=False, description="Auto-upload PDFs to Paperless")

+    volatile_ttl: int = Field(default=3600, description="TTL for reactive volatile cache")
+```
+
+---
+
+## Phase C: Document Recall in HybridRAG
+
+### C.1 Add Document Search
+
+**Modify:** `src/services/hybrid_rag_service.py`
+
+Add to `_retrieve_parallel()`:
+
+```python
+if config.enable_documents:
+    async def document_search():
+        results = await self.vector.search(
+            query=query,
+            user=user,

+            doc_type="document"  # Filter to Paperless docs
+        )
+        return [{"paperless_id": r.metadata.get("paperless_id"), ...} for r in results]
+
+    tasks["document"] = document_search()
+```
+
+### C.2 Config Options
+
+```python
+enable_documents: bool = Field(default=True)
+document_limit: int = Field(default=5)
+document_threshold: float = Field(default=0.6)
+```
+
+---
+
+## Example Flow
+
+1. **User searches:** "What's the weather in Amsterdam?"
+2. **HybridRAG web search:** Returns open-meteo.com or weather site result
+3. **Post-processor classifies:** Ephemeral weather content
+4. **Immediate store:** `POST /volatile/store` (TTL: 1h)
+5. **Prefetch detection:** Matches weather pattern
+6. **Scheduler registration:** Creates task `volatile_weather_amsterdam_jpmschweitzer`
+7. **Next day 6am:** Scheduler calls `/volatile/fetch/weather/amsterdam`
+8. **Future searches:** Get cached weather from volatile
+

+
+**wiki** - Stable reference content worth documenting permanently:
+- Factual information about people, places, companies, products
+- How-to guides, tutorials, technical documentation
+- Historical facts, biographies, definitions
+- Content that won't change frequently
+
+**volatile** - Ephemeral data that changes frequently:
+- Current weather conditions or forecasts
+- Latest news headlines or breaking news
+- Stock prices, exchange rates, crypto prices
+- Sports scores, live results
+- Traffic conditions, transit delays
+- Social media trends, notifications
+Use namespaces: weather, news, financial, transit, traffic, sports, social, system
+
+**file** - Downloadable documents:
+- PDF files (URLs ending in .pdf or containing /pdf/)
+- Office documents (.doc, .docx, .xls, .xlsx, .ppt)
+- Images (.jpg, .png, .gif when they're primary content)
+- CSV/data files
+- Any direct download link
+
+**prefetch** - Sources worth checking regularly:
+- News feeds or RSS sources
+- API endpoints with live data
+- Dashboards or status pages
+- Only if not already captured by volatile
+
+**skip** - Low value content:
+- Ads, paywalled content
+- Error pages, 404s
+- Duplicate or redundant results
+- Content not answering the query
