+# Learning & Context Schema
+
+**MSP Mode Database Schema - Self-Learning System**
+
+**Status:** Designed 2026-01-15
+**Database:** msp_tracking (MariaDB on Jupiter)
+
+---
+
+## Overview
+
+The Learning & Context subsystem enables MSP Mode to learn from every failure, build environmental awareness, and prevent recurring mistakes. This self-improving system captures failure patterns, generates actionable insights, and proactively checks environmental constraints before making suggestions.
+
+**Core Principle:** Every failure is a learning opportunity. Agents must never make the same mistake twice.
+
+**Related Documentation:**
+- [MSP-MODE-SPEC.md](../MSP-MODE-SPEC.md) - Full system specification
+- [ARCHITECTURE_OVERVIEW.md](ARCHITECTURE_OVERVIEW.md) - Agent architecture
+- [SCHEMA_CREDENTIALS.md](SCHEMA_CREDENTIALS.md) - Security tables
+- [API_SPEC.md](API_SPEC.md) - API endpoints
+
+---
+
+## Tables Summary
+
+| Table | Purpose | Auto-Generated |
+|-------|---------|----------------|
+| `environmental_insights` | Generated insights per client/infrastructure | Yes |
+| `problem_solutions` | Issue tracking with root cause and resolution | Partial |
+| `failure_patterns` | Aggregated failure analysis and learnings | Yes |
+| `operation_failures` | Non-command failures (API, file ops, network) | Yes |
+
+**Total:** 4 tables
+
+**Specialized Agents:**
+- **Failure Analysis Agent** - Analyzes failures, identifies patterns, generates insights
+- **Environment Context Agent** - Pre-checks environmental constraints before operations
+- **Problem Pattern Matching Agent** - Searches historical solutions for similar issues
+
+---
+
+## Table Schemas
+
+### `environmental_insights`
+
+Auto-generated insights about client infrastructure constraints, limitations, and quirks. Used by Environment Context Agent to prevent failures before they occur.

+
+Auto-generated from failure patterns and verified operations.
+
+## D2TESTNAS (192.168.0.9)
+
+### Custom Installations
+
+**WINS Service: Manual Samba installation**
+- Manually installed via Samba nmbd, not native ReadyNAS service
+- No GUI service manager for WINS
+- Configure via `/etc/frontview/samba/smb.conf.overrides`
+- Check status: `ssh root@192.168.0.9 'ps aux | grep nmbd'`
+
+### Network Constraints
+
+**SMB Protocol: CORE/SMB1 only**
+- For DOS compatibility
+- Modern SMB2/3 clients may need configuration
+- Use NetBIOS name from DOS machines
+
+## AD2 (192.168.0.6 - Server 2022)
+
+### PowerShell Version
+
+**Version:** PowerShell 5.1 (default)
+- **Compatible:** Modern cmdlets work
+- **Not available:** PowerShell 7 specific features
+
+## TS-XX Machines (DOS 6.22)
+
+### Command Constraints
+
+**No support for:**
+- `IF /I` (case insensitive) - use duplicate IF statements
+- Long filenames (8.3 format only)
+- Unicode or special characters
+- Modern batch features
+
+**Examples:**
+```batch
+REM Correct (DOS 6.22)
+IF "%1"=="STATUS" GOTO STATUS
+IF "%1"=="status" GOTO STATUS
+
+REM Incorrect (requires Windows 2000+)
+IF /I "%1"=="STATUS" GOTO STATUS

+
+## Self-Learning Workflow
+
+### 1. Failure Detection and Logging
+
+**Command Execution with Failure Tracking:**
+
+```
+User: "Check WINS status on D2TESTNAS"
+
+Main Claude → Environment Context Agent:
+  - Queries infrastructure table for D2TESTNAS
+  - Reads environmental_notes: "Manual WINS install, no native service"
+  - Reads environmental_insights for D2TESTNAS
+  - Returns: "D2TESTNAS has manually installed WINS (not native ReadyNAS service)"
+
+Main Claude suggests command based on environmental context:
+  - Executes: ssh root@192.168.0.9 'systemctl status nmbd'
+
+Command fails:
+  - success = false
+  - exit_code = 127
+  - error_message = "systemctl: command not found"
+  - failure_category = "command_compatibility"
+
+Trigger Failure Analysis Agent:
+  - Analyzes error: ReadyNAS doesn't use systemd
+  - Identifies correct approach: "service nmbd status" or "ps aux | grep nmbd"
+  - Creates failure_pattern entry
+  - Updates environmental_insights with correction
+  - Returns resolution to Main Claude
+
+Main Claude tries corrected command:
+  - Executes: ssh root@192.168.0.9 'ps aux | grep nmbd'
+  - Success = true
+  - Updates original failure record with resolution
+```
+
+### 2. Pattern Analysis (Periodic Agent Run)
+
+**Failure Analysis Agent runs periodically:**
+
+**Agent Task:** "Analyze recent failures and update environmental insights"
+
+1. **Query failures:**
+   ```sql
+   SELECT * FROM commands_run
+   WHERE success = false AND resolved = false
+   ORDER BY created_at DESC;
+
+   SELECT * FROM operation_failures
+   WHERE resolved = false
+   ORDER BY created_at DESC;
+   ```
+
+2. **Group by pattern:**
+   - Group by infrastructure_id, error_pattern, failure_category
+   - Identify recurring patterns
+
+3. **Create/update failure_patterns:**
+   - If pattern seen 3+ times → Create failure_pattern
+   - Increment occurrence_count for existing patterns
+   - Update last_seen timestamp
+
+4. **Generate environmental_insights:**
+   - Transform failure_patterns into actionable insights
+   - Create markdown-formatted descriptions
+   - Add command examples
+   - Set priority based on severity and frequency
+
+5. **Update infrastructure environmental_notes:**
+   - Add constraints to infrastructure.environmental_notes
+   - Set powershell_version, shell_type, limitations
+
+6. **Generate insights.md file:**
+   - Query all environmental_insights for client
+   - Format as markdown
+   - Save to D:\ClaudeTools\insights\[client-name].md
+   - Agents read this file before making suggestions
+
+### 3. Pre-Operation Environment Check
+
+**Environment Context Agent runs before operations:**
+
+**Agent Task:** "Check environmental constraints for D2TESTNAS before command suggestion"
+
+1. **Query infrastructure:**
+   ```sql
+   SELECT environmental_notes, powershell_version, shell_type, limitations
+   FROM infrastructure
+   WHERE id = 'd2testnas-uuid';
+   ```
+
+2. **Query environmental_insights:**
+   ```sql
+   SELECT insight_title, insight_description, examples, priority
+   FROM environmental_insights
+   WHERE infrastructure_id = 'd2testnas-uuid'
+     AND is_active = true
+   ORDER BY priority DESC;
+   ```
+
+3. **Query failure_patterns:**
+   ```sql
+   SELECT pattern_signature, recommended_solution, workaround_commands
+   FROM failure_patterns
+   WHERE infrastructure_id = 'd2testnas-uuid'
+     AND is_active = true;
+   ```
+
+4. **Check proposed command compatibility:**
+   - Proposed: "systemctl status nmbd"
+   - Pattern match: "systemctl.*command not found"
+   - **Result:** INCOMPATIBLE
+   - Recommended: "ps aux | grep nmbd"
+
+5. **Return environmental context:**
+   ```
+   Environmental Context for D2TESTNAS:
+   - ReadyNAS OS (Linux-based)
+   - Manual WINS installation (Samba nmbd)
+   - No systemd (use 'service' or ps commands)
+   - SMB1/CORE protocol for DOS compatibility
+
+   Recommended commands:
+   ✓ ps aux | grep nmbd
+   ✓ service nmbd status
+   ✗ systemctl status nmbd (not available)
+   ```
+
+Main Claude uses this context to suggest correct approach.

+## Integration with Other Schemas
+
+**Sources data from:**
+- `commands_run` - Command execution failures
+- `infrastructure` - System capabilities and limitations
+- `work_items` - Context for failures
+- `sessions` - Session context for operations
+
+**Provides data to:**
+- Environment Context Agent (pre-operation checks)
+- Problem Pattern Matching Agent (solution lookup)
+- MSP Mode (intelligent suggestions)
+- Reporting (failure analysis, improvement metrics)

+## Example Queries
+
+### Find all insights for a client
+```sql
+SELECT ei.insight_title, ei.insight_description, i.hostname
+FROM environmental_insights ei
+JOIN infrastructure i ON ei.infrastructure_id = i.id
+WHERE ei.client_id = 'dataforth-uuid'
+  AND ei.is_active = true
+ORDER BY ei.priority DESC;
+```
+
+### Search for similar problems
+```sql
+SELECT ps.problem_title, ps.solution_applied, ps.created_at
+FROM problem_solutions ps
+WHERE MATCH(ps.problem_description, ps.symptom, ps.error_message)
+      AGAINST('SSL certificate' IN BOOLEAN MODE)
+ORDER BY ps.created_at DESC
+LIMIT 10;
+```
+
+### Active failure patterns
+```sql
+SELECT fp.pattern_signature, fp.occurrence_count, fp.recommended_solution
+FROM failure_patterns fp
+WHERE fp.is_active = true
+  AND fp.severity IN ('blocking', 'major')
+ORDER BY fp.occurrence_count DESC;
+```
+
+### Unresolved operation failures
+```sql
+SELECT of.operation_type, of.target_system, of.error_message, of.created_at
+FROM operation_failures of
