# Ralph Epic #26: Practical Examples **Version**: 1.0.0 **Date**: 2026-02-03 **Epic**: [#26](https://git.integrolabs.net/roctinam/ai-writing-guide/issues/26) --- ## Overview This document shows the Epic #26 four-layer intelligence system in action through realistic scenarios. Each example demonstrates how PID Control, Claude Intelligence, Memory, and Overseer layers work together to provide adaptive, self-managing loop behavior. **Layer Quick Reference**: - **Layer 1 (PID)**: Metrics + control signals + alarms - **Layer 2 (Intelligence)**: Strategy + validation + dynamic prompts - **Layer 3 (Memory)**: Cross-loop learning + knowledge retrieval - **Layer 4 (Overseer)**: Health monitoring + intervention + escalation --- ## Example 1: Fixing Failing Tests **Scenario**: 5 authentication tests failing after a refactor. Ralph loop should identify root cause, fix code, and verify all tests pass. ### Configuration ```javascript await orchestrator.execute({ objective: "Fix failing authentication tests", completionCriteria: "All tests in test/auth/** pass", maxIterations: 10, budgetPerIteration: 2.0, // Standard profile - balanced for typical bug fixes enablePIDControl: true, pidConfig: { initialProfile: 'standard', adaptiveGains: true, }, // Validation: Run tests post-iteration validation: { postIteration: { checkTests: true, testPattern: 'test/auth/**', }, }, // Full oversight enableOverseer: true, enableSemanticMemory: true, }); ``` ### Iteration 1: Initial Assessment **Layer 1 - PID Control**: ```yaml metrics: proportional: 1.0 # 0% complete (5 tests failing) integral: 0.0 # No accumulated error yet derivative: 0.0 # No trend yet gains: profile: exploration # Early phase: low gains kp: 0.3 ki: 0.1 kd: 0.2 control_signal: 0.3 # Low urgency early on alarm_status: NORMAL ``` **Layer 2 - Claude Intelligence**: ```yaml state_assessment: estimated_progress: 0% phase: initial_investigation blockers: - "5 tests failing: test_token_validation, test_password_hash, ..." strategy: approach: investigate reasoning: "First iteration - need to understand test failures" priorities: - "Read test output and identify failure patterns" - "Check test files for common cause" - "Review recent refactor changes" prompt_generated: urgency: normal focus_areas: - "Analyze test failure messages" - "Locate authentication module changes" - "Identify root cause" tool_suggestions: [Bash, Grep, Read] ``` **Layer 3 - Memory**: ```yaml retrieved_knowledge: strategies: - type: strategy content: "For test fixes, start with test file to understand expectations" confidence: 0.85 success_rate: 0.80 source_loops: [ralph-005, ralph-012] antipatterns: - type: antipattern content: "Don't modify tests to pass - fix the code being tested" confidence: 0.95 estimates: - type: estimate content: "Test fixes typically take 2-3 iterations" confidence: 0.70 ``` **Layer 4 - Overseer**: ```yaml health_check: status: healthy detections: [] interventions: [] message: "Loop started, monitoring for pathologies" ``` **Iteration 1 Output**: Claude analyzes test output, identifies that token validation is failing because the refactor changed the token signing algorithm but tests still expect the old format. --- ### Iteration 2: First Fix Attempt **Layer 1 - PID Control**: ```yaml metrics: proportional: 0.8 # 20% complete (4/5 tests now pass) integral: 1.8 # Accumulated: 1.0 + 0.8 derivative: -0.2 # Improving (was 1.0, now 0.8) gains: profile: focused # Phase advanced, use focused gains kp: 0.5 ki: 0.2 kd: 0.3 control_signal: 0.54 # (0.5×0.8) + (0.2×1.8) + (0.3×-0.2) = 0.54 alarm_status: NORMAL trend: improving ``` **Layer 2 - Claude Intelligence**: ```yaml state_assessment: estimated_progress: 20% phase: iterative_fixing blockers: - "1 test still failing: test_password_hash" strategy: approach: persist reasoning: "Making good progress (1 of 5 fixed), continue current approach" priorities: - "Fix remaining test_password_hash failure" - "Verify no regressions in passing tests" validation: post_iteration: tests_run: 5 tests_passed: 4 tests_failed: 1 regression_detected: false ``` **Layer 4 - Overseer**: ```yaml health_check: status: healthy detections: [] interventions: - level: LOG message: "Positive progress: 4/5 tests passing (+1 from last iteration)" ``` **Iteration 2 Output**: Claude fixes the token validation issue. Now 4 tests pass, but `test_password_hash` still fails due to unrelated bcrypt salt issue. --- ### Iteration 3: Addressing Edge Case **Layer 1 - PID Control**: ```yaml metrics: proportional: 0.6 # 40% complete (now addressing password hash) integral: 2.3 # Accumulated: 1.8 + 0.5 (decay applied) derivative: -0.2 # Still improving gains: profile: focused kp: 0.5 ki: 0.2 kd: 0.3 control_signal: 0.61 alarm_status: NORMAL ``` **Layer 2 - Validation**: ```yaml pre_iteration_validation: passed: true issues: [] post_iteration_validation: tests_run: 5 tests_passed: 5 tests_failed: 0 regression_detected: false severity: ok ``` **Layer 3 - Memory**: ```yaml learning_extracted: - type: strategy task_type: test-fix content: approach: "Start with test output, trace to root cause in implementation" tool_sequence: [Bash, Grep, Read, Edit, Bash] iterations_taken: 3 confidence: 0.85 - type: convention task_type: general content: "Authentication tests require bcrypt salt rounds to be deterministic" confidence: 0.90 ``` **Layer 4 - Overseer**: ```yaml health_check: status: excellent detections: [] interventions: - level: LOG message: "All tests passing - completion detected" completion_detected: true ``` **Iteration 3 Output**: Claude fixes bcrypt salt configuration. All 5 tests now pass. --- ### Loop Completion Summary **PID Trajectory**: ``` Iteration | P | I | D | Control | Alarm ----------|-------|------|-------|---------|------- 1 | 1.0 | 0.0 | 0.0 | 0.30 | NORMAL 2 | 0.8 | 1.8 | -0.2 | 0.54 | NORMAL 3 | 0.6 | 2.3 | -0.2 | 0.61 | NORMAL ``` **Memory Promoted**: - Strategy: "Test-first debugging for auth failures" (confidence: 0.85) - Convention: "Bcrypt salt must be deterministic in tests" (confidence: 0.90) **Outcome**: - All tests passing - 3 iterations (within estimate) - No interventions required - Knowledge learned and stored for future loops --- ## Example 2: TypeScript Migration (Incremental Progress) **Scenario**: Migrate 20 JavaScript files to TypeScript.

Complexity increasing as easier files are done. --- ### Iteration 10-12: Recovery and Acceleration **Layer 2 - Strategy** (Iteration 10): ```yaml strategy: approach: pivot reasoning: "Adopt new strategy to address complex dependencies" new_priorities: - "Create shared types file first" - "Then convert files that depend on shared types" - "Use top-down approach instead of bottom-up" ``` **Layer 1 - PID Control** (Iteration 12): ```yaml metrics: proportional: 0.35 # 65% complete (13/20 files) integral: 4.8 # Decreased due to decay derivative: -0.15 # Accelerated again (good strategy change) gains: profile: focused kp: 0.5 ki: 0.15 kd: 0.25 control_signal: 0.52 alarm_status: NORMAL # Back to normal ``` **Progress**: Strategy pivot worked. Velocity increased. --- ### Iteration 13-15: Final Push **Layer 1 - PID Control** (Iteration 15): ```yaml metrics: proportional: 0.0 # 100% complete integral: 0.5 derivative: -0.35 # Strong final velocity gains: profile: cautious # Returned to cautious near completion kp: 0.2 ki: 0.02 kd: 0.5 control_signal: 0.03 # Near zero - completion ``` **Layer 3 - Memory Promotion**: ```yaml learnings_promoted: - type: strategy content: "For TypeScript migration: create shared types first, then convert dependents" confidence: 0.90 iterations_taken: 15 - type: estimate content: "TypeScript migration: ~0.75 iterations per file" confidence: 0.85 source_loops: [ralph-current] ``` **Outcome**: - All 20 files converted - Build passing, tests passing - 15 iterations (good match to estimate) - PID adapted through plateau successfully - Memory captured successful pivot strategy --- ## Example 3: Security Vulnerability Fix (Conservative Mode) **Scenario**: OWASP vulnerability detected in authentication module. High-stakes task requiring strict oversight. ### Configuration ```javascript await orchestrator.execute({ objective: "Fix OWASP A02:2021 crypto failure in auth module", completionCriteria: "Security scan passes, all tests pass, no new vulnerabilities", maxIterations: 8, budgetPerIteration: 3.0, // Conservative mode for security pidConfig: { initialProfile: 'conservative', adaptiveGains: false, // Keep conservative throughout }, validation: { preIteration: { checkBuild: true, checkLint: true, }, postIteration: { checkTests: true, runSecurityScan: true, }, }, overseer: { autoEscalate: true, stuckThreshold: 2, // Stricter stuck detection pauseOnCritical: true, }, }); ``` ### Iteration 1: Investigation **Layer 1 - PID Control**: ```yaml metrics: proportional: 1.0 integral: 0.0 derivative: 0.0 gains: profile: conservative kp: 0.3 # Low proportional ki: 0.05 # Very low integral kd: 0.4 # High derivative for stability control_signal: 0.30 alarm_status: NORMAL ``` **Layer 2 - Validation**: ```yaml pre_iteration_validation: passed: true warnings: - "Security-sensitive task - extra validation enabled" - "All changes will be scrutinized" ``` **Iteration 1 Output**: Identified that auth module uses MD5 for token hashing (insecure).

Prioritize: remove hardcoded key, complete HMAC migration" ``` **Iteration 2 Output**: Validation caught incomplete fix. Loop redirected to address security gaps. --- ### Iteration 3: Addressing Feedback **Layer 2 - Strategy**: ```yaml strategy: approach: focused_remediation reasoning: "Validation failures guide next steps" priorities: - "Remove hardcoded secret, load from environment" - "Complete HMAC-SHA256 migration for all token operations" - "Update tests to verify new crypto" ``` **Layer 2 - Validation**: ```yaml post_iteration_validation: tests_passed: true security_scan: status: PASS issues: [] severity: ok ``` **Layer 4 - Overseer**: ```yaml health_check: status: excellent detections: [] interventions: - level: LOG message: "Security scan passing, all tests green - completion detected" completion_detected: true ``` **Iteration 3 Output**: All security issues resolved.
