Changelog

All notable changes to the Agentic QE project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[3.7.14] - 2026-03-08

Added

  • Brain Export v3.0 — full 25-table portable intelligence — Completely rebuilt brain export/import to cover all 25 learning tables (up from 4). Data-driven TABLE_CONFIGS pattern replaces hardcoded per-table logic, with FK-aware ordering, Base64 BLOB serialization, and automatic DDL creation on import.
  • Streaming export for large tables — Tables exceeding 10K rows (e.g., concept_edges) now stream directly to JSONL via writeJsonlStreaming() using synchronous fd I/O, avoiding OOM on large databases.
  • Witness chain v3 with SHAKE-256 + Ed25519 signing — Dual hash algorithm support (sha256/shake256), 12 witness action types wired to production mutation sites (dream merge/discard, branch merge, Hebbian penalty, routing decisions, pattern quarantine), and Ed25519 key persistence with PEM files.
  • Witness backfill CLI — aqe brain witness-backfill command replays existing patterns/Q-values/dream insights into the witness chain for databases created before witness integration.
  • RVF adapter: freeze, derive, indexStats — freeze() makes RVF files immutable after signing, derive() supports COW branching with native fallback, indexStats() exposes HNSW index metrics.
  • RVF manifest sidecar — Brain RVF exports now write a {path}.manifest.json sidecar with full export metadata alongside the binary container.
  • Brain CLI lineage & signature display — aqe brain info now shows RVF file lineage (fileId, parentId, depth) and signature status (keyId, truncated signature).

Fixed

  • npm install ENOTEMPTY error — Reduced npm package from 5,473 to 3,293 files by excluding test fixtures, build artifacts, and development-only directories via .npmignore.
  • ReDoS vulnerability in trigger-optimizer — Replaced vulnerable regex pattern with safe alternative.
  • Import atomicity — Brain import now wraps all table merges in a single db.transaction() for atomic rollback on failure.
  • Domain collection in streaming path — Fixed SQL syntax error when collecting domains from qe_patterns that exceeded the streaming threshold.

Changed

  • Brain export manifest version bumped from 1.0 to 3.0 with tableRecordCounts breakdown.
  • Merge engine now supports 4 strategies: latest-wins, highest-confidence, union, skip-conflicts.
  • ADRs updated: ADR-065 (RVF integration), ADR-070 (witness chain), ADR-073 (portable intelligence containers).

[3.7.13] - 2026-03-07

Added

  • Trigger Optimizer — Analyzes skill descriptions and tags to detect false positive/negative activation risks. Calculates Jaccard similarity across the skill fleet, identifies confusable skills, and generates actionable suggestions to improve trigger precision.
  • Version Comparator — A/B testing between skill versions using Cohen's d effect size and confidence scoring. Produces per-test-case comparisons and Markdown reports for data-driven skill improvement decisions.
  • Skill Intent Classification — New skill_intent frontmatter field classifies skills as capability_uplift (fills model gaps), encoded_preference (encodes team workflows), or hybrid. Drives different validation strategies per intent type.

Changed

  • ADR-056 updated with Phase 6 (Blog-Inspired Improvements) documenting the three new features.
  • Validation module index now exports TriggerOptimizer, VersionComparator, and all associated types.

[3.7.12] - 2026-03-06

Fixed

  • CLI crash on global install — aqe --version crashed with ERR_MODULE_NOT_FOUND: Cannot find package 'typescript' when installed globally (npm i -g agentic-qe). TypeScript was marked as an external ESM dependency in the build but is only a devDependency, so it's absent in clean environments. Now lazy-loaded via createRequire Proxy — only loads when AST parsing features are actually used.
  • Release skill missing isolated install check — Added pre-release step 8e (isolated dependency check) and post-publish step 15 (clean-environment install verification) to catch missing external dependencies before they reach users.

[3.7.11] - 2026-03-06

Added

  • Full @claude-flow/guidance governance integration — All 8 governance modules now properly load AND wire their guidance counterparts using a local-first pattern where AQE logic is authoritative and guidance supplements:
    • continue-gate: Maps ContinueDecision with full StepContext for budget-aware loop control
    • memory-write-gate: Local-first contradiction detection, guidance supplements via evaluateWrite()
    • adversarial-defense: ThreatDetector.analyzeInput() supplements local pattern detection; new recordAgentInteraction() and detectCollusion() methods via CollusionDetector
    • deterministic-gateway: gateway.evaluate() supplements local tool-call allow/deny gating
    • proof-envelope: Parallel audit trail mirroring via ProofChain.append()
    • shard-retriever: Embedding-based relevance boosting via ShardRetriever.retrieve()
    • evolution-pipeline: Signed change proposals via EvolutionPipeline.propose() on rule promote/demote
    • trust-accumulator: Guidance trust scoring integration
  • Governance subpath export — Users can now import {} from 'agentic-qe/governance'

Fixed

  • ContinueGate mapGuidanceDecision read wrong property names — Was reading decision.shouldContinue / .reason / .throttleMs which don't exist on ContinueDecision; now correctly reads decision.decision, decision.reasons, decision.metrics
  • MemoryWriteGate evaluation order — Guidance was running before local logic; reversed to local-first so AQE's contradiction detection is authoritative
  • ContinueGate StepContext was Partial — Now provides full StepContext with realistic budget values derived from actual history
  • Security: ReDoS guards — Added line-length guards for all regex matches (CWE-1333)

[3.7.10] - 2026-03-05

Fixed

  • MCP server entry path resolution — aqe mcp command failed with "Could not find MCP server entry point" because findMcpEntry() traversed 2 directory levels instead of 1 from dist/cli/ to find dist/mcp/bundle.js
  • Stale v3/ directory references — Worker daemon and MCP command lookup referenced node_modules/agentic-qe/v3/dist/ which no longer exists after the v3.7.5 flatten; updated to node_modules/agentic-qe/dist/
  • CRLF line endings breaking skill frontmatter — 170+ skill files had Windows-style \r\n line endings causing skill-lint YAML parsers to fail on ---\r delimiters; all converted to LF
  • CI Node.js version — Upgraded all 8 CI workflow files from Node.js 20 to Node.js 24

Changed

  • README rewritten for clarity — Reduced from 1,097 to ~280 lines; restructured around user outcomes instead of internal architecture details
  • Asset build safety — prepare-assets.sh now strips CRLF line endings and removes .DS_Store files as a safety net during asset preparation

[3.7.9] - 2026-03-05

Added

  • Multi-language test generation — 8 new generators: Go (go test), Rust (#[cfg(test)]), Kotlin (JUnit5), Java (JUnit5), Swift (Swift Testing), Flutter (flutter_test), React Native (Jest), and C# (xUnit). Each generator produces idiomatic tests with language-specific patterns (e.g., Rust ownership analysis, Go table-driven tests)
  • Compilation validation loop — Validates generated tests compile before output, with framework-specific fix strategies
  • Language detection — Automatic source language detection to route to the correct test generator
  • Trust tier eval infrastructure — Full eval configs (YAML test cases, JSON schemas, validator scripts) for 5 skills: qcsd-cicd-swarm, qcsd-development-swarm, enterprise-integration-testing, observability-testing-patterns, middleware-testing-patterns

Fixed

  • Embedding dimension standardization — All vector dimensions unified to 384 (all-MiniLM-L6-v2), fixing mixed 384/768 dimensions across providers, tests, and config defaults
  • Agent memory namespace paths — Normalized namespace references in agent definitions to prevent orphaned records
  • Asset sync coverage — prepare-assets.sh now includes all 78 QE skills (previously missed 24 skills including qcsd-, n8n-, and other non-prefixed skills)

Changed

  • Default embedding model — Switched from nomic-embed-text to all-MiniLM-L6-v2 for consistent 384-dim vectors across all providers
  • Trust tier adjustments — debug-loop and pr-review set to tier 0 (advisory-only, no eval infrastructure needed)

[3.7.8] - 2026-03-04

Added

  • Loki-Mode adversarial quality gates (ADR-074) — 7 new features to catch sycophantic AI outputs, hollow tests, and routing drift. All enabled by default (opt-out via config flags):
    • Anti-sycophancy scorer: Detects rubber-stamp consensus via Jaccard similarity, confidence uniformity, and reasoning overlap across model votes
    • Test quality gates: Catches tautological assertions (expect(true).toBe(true)), empty test bodies, and missing source imports in generated tests
    • Blind review orchestrator: Runs N parallel test generators with varied temperatures, deduplicates results via Jaccard similarity
    • EMA calibration: Exponential moving average tracks per-agent accuracy and derives dynamic voting weights, with SQLite state persistence
    • Edge-case injection: Queries historical patterns from the learning store and injects proven edge cases into test generation prompts
    • Complexity-driven team composition: Maps 8-dimension complexity analysis (AST + security + concurrency + API surface) to agent team composition
    • Auto-escalation tracker: Consecutive failures auto-promote agent tier; consecutive successes auto-demote for cost optimization
  • Smart experience consolidation — Replace destructive pruning with intelligent consolidation that preserves high-value learning patterns while managing memory growth
  • Multi-language test generation plan — Architecture decision records (ADR-075 through ADR-079) for unified test framework type system, Tree-sitter WASM parser, compilation validation loop, backward-compatible API, and language-specific path resolution

Changed

  • Loki-mode features enabled by default — All 6 config flags (enableSycophancyCheck, enableTestQualityGate, enableEdgeCaseInjection, enableEMACalibration, enableAutoEscalation, enableComplexityComposition) default to true for immediate quality improvement

[3.7.7] - 2026-03-02

Added

  • Resource blocking for E2E tests — Block non-essential resources (images, fonts, tracking, ads) during test execution with three presets: functional (fastest, blocks all non-essential), visual (blocks nothing), and performance (blocks heavy resources). Includes domain-based tracker/ad detection for 30+ known domains.
  • Adaptive locator for resilient selectors — When a CSS/XPath selector fails, falls back to text, ARIA, and similarity-based fingerprint matching to find the intended element. Reduces E2E flakiness when UI changes break selectors. Weighted scoring across tag name, ARIA role, classes, text content, attributes, and DOM position.
  • Browser page pool — Manages concurrent browser page lifecycle with async acquire/release, health-based pruning, and pool statistics. Async waiters are notified when pages become available.
  • Stealth browser client via Patchright — Optional IBrowserClient implementation using Patchright (drop-in Playwright replacement) for bot-protected test environments. Supports persistent contexts, Cloudflare challenge detection, proxy configuration, and integrated resource blocking. Lazy-loaded so it doesn't affect builds when not installed.
  • stealth-testing browser use case — New use case in the browser client factory for intelligent tool selection when testing against bot-protected sites.

Changed

  • Step executors use adaptive locator — Click and type steps now resolve element targets through the adaptive fallback chain when configured, using the actual page URL (not just base URL) for fingerprint keying.
  • Resource blocking wired into browser orchestrator — applyResourceBlocking() calls abortRoute() on agent-browser clients for tracker/ad domains during test launch.
  • getBrowserToolAvailability() includes stealth — Return type now includes stealth: boolean alongside vibium and agent-browser.

Security

  • Fix JS injection in adaptive locator — Text fallback now uses JSON.stringify() instead of manual escaping to safely interpolate stored text content into browser-evaluated scripts.

[3.7.6] - 2026-03-02

Security

  • Resolve all 9 GitHub code scanning alerts — Fix DOM XSS in sorter (innerHTML → createElement), weak password hash in test fixture (SHA-512 → scrypt), incomplete URL sanitization in OAuth tests, prototype pollution flags, and incomplete hostname regex escaping

Added

  • 26 MCP tools wired via QE tool bridge — Register previously unwired QE tools (GOAP planning, embeddings, coherence, mincut, learning, coverage gaps, QX partner, and more) through new qe-tool-bridge.ts
  • 4 new MCP tools with CLI support — Test scheduling with git-aware selection (qe/tests/schedule), agent fleet load testing (qe/tests/load), URL threat detection with PII scanning (qe/security/url-validate), and YAML browser workflow loading (qe/workflows/browser-load)
  • Fleet health enriched with structural metrics — fleet_health now includes mincut-lambda from real agent connectivity analysis

Changed

  • Remove 7 dead devDependencies — Drop rimraf, tinybench, ts-node, typedoc, stack-utils, graceful-fs, eslint-plugin-security; move @faker-js/faker to runtime dependencies where it's actually used
  • Archive neural-optimizer module — Move RL-based topology optimizer to src/_archived/ (overkill for typical 6-15 agent fleets; restorable when 100+ agent fleets become common)
  • Delete dead code — Remove unused qe-tools.ts (935 lines), obsolete publish-v3-alpha.yml workflow, 9 Istanbul static assets from src/coverage/

[3.7.5] - 2026-03-01

Changed

  • Flat project structure — Archived v2, promoted v3 to root. All source (src/, dist/, tests/) now lives at project root with a single package.json. Removes the dual-package complexity and simplifies the build pipeline.
  • Updated release workflow — /release skill rewritten for single-package flat structure (no more v3/ paths)

Added

  • RVF binary brain export — Native @ruvector/rvf-node integration for exporting learning patterns to compact binary .rvf format
  • Multi-platform coding agent support (v3.7.4) — 8 new platforms (Copilot, Cursor, Cline, Kilo Code, Roo Code, Codex CLI, Windsurf, Continue.dev) with --with-all-platforms flag, platform CLI commands, and 103 new tests

Fixed

  • @ruvector native module crashes — Graceful fallback on platforms without native binaries (#314, #315)
  • Stale v3/ path references — Cleaned up post-flatten; protected memory namespaces from accidental renames
  • Release notes corrections — Fixed alwaysAllow count, stale plan references

[2.3.0] - 2025-12-08

Added

Automatic Learning Capture (Major Feature)

Implemented PostToolUse hook that automatically captures Task agent learnings without requiring agents to explicitly call MCP tools. This solves the long-standing issue where Task agents would not reliably persist learning data.

New Files:

  • scripts/hooks/capture-task-learning.js - PostToolUse hook for automatic learning capture
    • Captures agent type, task output, duration, and token usage
    • Calculates reward based on output quality indicators
    • Stores to learning_experiences table in memory.db
    • Deduplication: Skips if agent already stored learning via MCP (60s window)

Updated aqe init:

  • Now copies hook scripts to user projects (scripts/hooks/)
  • New phase: "Hook Scripts" in initialization pipeline
  • Settings.json includes automatic learning capture hook

How It Works:

Task Agent Completes → PostToolUse Hook Fires → capture-task-learning.js:
  • Extracts agent type, output, duration from hook input
  • Calculates reward (0.7 base + quality bonuses)
  • Checks for duplicates (60s deduplication window)
  • Stores to learning_experiences table
→ 📚 Learning captured: qe-test-generator → test-generation (reward: 0.85)

Clean QE-Only Configuration

Removed all claude-flow and agentdb dependencies from QE agents:

  • Updated settings.json with clean AQE env vars (AQE_MEMORY_PATH, AQE_MEMORY_ENABLED, AQE_LEARNING_ENABLED)
  • Removed agentdb.db references (deprecated)
  • All persistence unified to .agentic-qe/memory.db
  • Updated claude-config.ts to generate clean hooks for aqe init

Agent Learning Instructions Audit

Added MANDATORY <learning_protocol> sections to all 30 QE agents:

  • 19 main QE agents updated
  • 11 QE subagents updated
  • Instructions include: query past learnings, store experiences, store patterns
  • MCP tool examples with proper parameters

Changed

  • src/cli/init/claude-config.ts - Clean QE-only hooks using memory.db via better-sqlite3
  • src/cli/init/helpers.ts - Added copyHookScripts() function
  • src/cli/init/index.ts - Added "Hook Scripts" phase to initialization
  • .claude/settings.json - Removed claude-flow hooks, updated to use memory.db

Fixed

  • Learning Persistence: Task agents now have learnings captured automatically via PostToolUse hook
  • Database Fragmentation: Unified all persistence to single memory.db database
  • Hook Schema Mismatch: Fixed INSERT statement to match actual learning_experiences table schema

[2.2.2] - 2025-12-07

[1.9.4] - 2025-11-30

🔧 Critical Fixes: Memory/Learning/Patterns System

This release delivers critical fixes to the memory, learning, and patterns system based on thorough investigation (Sherlock Investigation Report). All QE agents now have a fully functional learning system with proper vector embeddings, Q-value reinforcement learning, and persistent pattern storage.

Fixed

  • Vector embeddings now stored correctly (was storing NULL): Fixed RealAgentDBAdapter.store() to properly store 384-dimension embeddings as BLOB data instead of NULL
  • SQL parameter style bug: Fixed agentdb's SqlJsDatabase wrapper to use spread params (stmt.run(a, b, c)) instead of array params (stmt.run([a,b,c])) which caused "NOT NULL constraint failed" errors
  • HNSW index schema mismatch: Added pattern_id generated column for agentdb's HNSWIndex compatibility which requires this column for vector search
  • Learning experience retrieval: Added missing getter methods that were referenced but didn't exist
  • Hooks saving to wrong database: Fixed all Claude Code hooks to explicitly export AGENTDB_PATH=.agentic-qe/agentdb.db so learning data is saved to the project database instead of the root directory
  • CI failures due to ARM64-only ruvector packages: Moved @ruvector/node-linux-arm64-gnu and ruvector-core-linux-arm64-gnu from dependencies to optionalDependencies. Added x64 variants for CI compatibility

Added

  • New SwarmMemoryManager methods for learning data retrieval:

    • getBestAction(agentId, stateKey) - Q-learning best action selection
    • getRecentLearningExperiences(agentId, limit) - Recent experience retrieval
    • getLearningExperiencesByTaskType(agentId, taskType, limit) - Task-filtered experiences
    • getHighRewardExperiences(agentId, minReward, limit) - Successful experience extraction
    • getLearningStats(agentId) - Aggregate learning statistics (total, avg, max, min rewards)

  • Hooks integration: Added AGENTDB_PATH environment variable to connect Claude Code hooks to the QE database

  • New modules (Phase 4 Alerting & Reporting):

    • src/alerting/ - AlertManager, FeedbackRouter, StrategyApplicator (1,394 LOC)
    • src/reporting/ - ResultAggregator, reporters (3,030 LOC)
    • Quality gate scripts and GitHub Actions workflow

  • Integration test: tests/integration/memory-learning-loop.test.ts - Comprehensive 7-phase test validating the full learning cycle:

    1. Pattern storage with embeddings
    2. Learning experience capture
    3. Q-value reinforcement learning
    4. Memory persistence
    5. Pattern retrieval
    6. Vector similarity search
    7. Full learning loop simulation

Changed

  • RealAgentDBAdapter: Now properly retrieves stored embeddings when querying patterns instead of using placeholder values
  • Pattern table schema: Added generated column pattern_id TEXT GENERATED ALWAYS AS (id) STORED for HNSW compatibility

Technical Details

  • Vector embeddings: 384 dimensions × 4 bytes = 1,536 bytes per pattern
  • AgentDB version: v1.6.1 with ReasoningBank (16 learning tables)
  • HNSW index: 150x faster vector search enabled
  • All 12 integration tests pass

[1.9.3] - 2025-11-26

🐛 Bugfix: NPM Package Missing Files

This patch release fixes missing files in the npm package that caused aqe init to fail.

Fixed

  • Added missing directories to npm package (package.json files array):
    • templates/ - Contains aqe.sh wrapper script
    • .claude/helpers/ - Contains 6 helper scripts
    • docs/reference/ - Contains reference documentation

[1.9.2] - 2025-11-26

🐛 Critical Bugfix: Learning Persistence

This patch release fixes a critical issue where learning data was not being persisted to SQLite.

Fixed

  • Learning data now persists to SQLite database (Issue #79): Root cause was missing columns in database schema and MemoryStoreHandler not actually writing to SQLite when persist: true was set.
    • Added missing columns to patterns table: domain, success_rate
    • Added missing column to q_values table: metadata
    • Added missing columns to learning_experiences table: metadata, created_at
    • Added database migrations for existing databases
    • MemoryStoreHandler now properly persists to SQLite when persist: true

Added

  • Verification script: scripts/verify-issue-79-fix.ts for testing learning persistence

[1.9.1] - 2025-11-25

🐛 Bugfixes & Documentation Improvements

This patch release fixes several issues discovered after the v1.9.0 release.

Fixed

  • Removed unwanted .gitignore creation: aqe init no longer creates a .gitignore file in the .agentic-qe/ directory. Users should add .agentic-qe/ entries to their root .gitignore instead.
  • Fixed aqe learn status database error: Resolved "no such column: agent_id" error by adding database migration for existing databases that lack the agent_id column in the patterns table.
  • Fixed aqe learn metrics SQL query: Corrected parameterized query to use the type column instead of non-existent agent_id column.
  • Updated init success message: Corrected CLI command suggestions (changed aqe fleet status to aqe status).

Changed

  • Documentation updates: Updated USER-GUIDE.md with correct CLI commands and MCP tool references for coverage analysis.

🔧 Init Command Refactoring (2025-11-23)

Major Refactoring

Converted Monolithic Init to Modular Architecture

Refactored src/cli/commands/init.ts from a single 2,700-line file into a clean, modular structure in src/cli/init/ for better maintainability, testability, and clarity.

Security

🔒 CRITICAL: Shell Injection Fix (src/cli/init/claude-config.ts:92-166):

  • Fixed shell injection vulnerability in Claude Code hooks that could allow arbitrary command execution
  • All hook commands now use jq -R '@sh' for proper shell escaping of file paths and user input
  • Severity: HIGH - Prevents malicious file names like "; rm -rf /; echo "pwned.txt from executing arbitrary commands
  • Impact: All PreToolUse, PostToolUse hook commands now secure against shell metacharacter injection
  • Testing: Verified with malicious file path scenarios - properly escaped as single quoted strings

Performance

⚡ Parallel Phase Execution (src/cli/init/index.ts:142-206):

  • Init command now executes non-critical phases concurrently using Promise.allSettled()
  • Speedup: 2-3 seconds faster on aqe init (from ~8s to ~5-6s)
  • Phases parallelized:
    • Documentation copying (.agentic-qe/docs)
    • Bash wrapper creation (aqe script)
    • CLAUDE.md generation
    • Agent template copying (.claude/agents)
    • Skills template copying (.claude/skills)
    • Command template copying (.claude/commands)
    • Helper scripts copying (.claude/helpers)
  • Safety: Critical phases (directories, databases, Claude config) still run sequentially
  • Graceful degradation: Non-critical phase failures logged as warnings, don't block init

Refactoring

🔧 Centralized Template Path Resolution (src/cli/init/utils/path-utils.ts:80-192):

  • Added getPackageRoot() function that searches upward for package.json with name verification
  • Added resolveTemplatePath() with 4-tier fallback logic:
    1. Project root templates/ (user customization)
    2. Package root templates/ (development)
    3. node_modules/agentic-qe/templates/ (installed package)
    4. ../node_modules/agentic-qe/templates/ (monorepo scenario)
  • Updated modules:
    • bash-wrapper.ts - Now uses resolveTemplatePath('aqe.sh')
    • documentation.ts - Now uses getPackageRoot() for docs location
  • Benefits:
    • Eliminates fragile hardcoded paths like __dirname/../../../templates
    • Works in development, installed package, and monorepo scenarios
    • Clear error messages showing all searched paths if template not found
    • Supports user customization by checking project root first

Changed

Modular Structure (src/cli/init/ - 14 modules):

  • ✅ index.ts - Main orchestrator with phase-based execution
  • ✅ agents.ts - Agent template copying (19 main + 11 subagents)
  • ✅ skills.ts - QE skill filtering and copying (40 skills)
  • ✅ helpers.ts - Helper scripts management
  • ✅ commands.ts - Slash command templates
  • ✅ claude-config.ts - Settings.json generation with AgentDB hooks
  • ✅ claude-md.ts - CLAUDE.md documentation generation
  • ✅ database-init.ts - AgentDB + Memory database initialization
  • ✅ directory-structure.ts - Project directory creation
  • ✅ documentation.ts - Reference docs copying
  • ✅ fleet-config.ts - Fleet configuration management
  • ✅ bash-wrapper.ts - aqe command wrapper creation
  • ✅ utils/ - 7 shared utility modules
  • ✅ README.md - Module documentation

Old Init Command (src/cli/commands/init.ts):

  • Now a thin 46-line wrapper that delegates to modular orchestrator
  • Preserved backward compatibility
  • All original functionality maintained

Added

New Skills (7 total, bringing total from 38 to 40):

  1. accessibility-testing - WCAG 2.2 compliance testing
  2. shift-left-testing - Early testing in SDLC
  3. shift-right-testing - Production monitoring and testing
  4. verification-quality - Comprehensive QA with truth scoring
  5. visual-testing-advanced - AI-powered visual regression
  6. xp-practices - XP practices (pair programming, ensemble)
  7. technical-writing - Documentation and communication

  • Alphabetically sorted patterns for maintainability
  • Comment documenting total count (40 QE skills)

Improved

Init Process (10 Phases):

  1. Directory Structure - Project directories and .gitignore
  2. Databases - AgentDB (16 tables) + Memory (12 tables)
  3. Claude Configuration - Settings.json with learning hooks + MCP server

🔧 Critical Fixes

Fixed

🐛 Memory Manager Fragmentation

  • Root Cause: Multiple isolated SwarmMemoryManager instances (MCP server, AgentRegistry, Phase2Tools each created their own)
  • Solution: Implemented singleton pattern via MemoryManagerFactory
  • Result: All components now share the same database connection

🐛 Database Closure on Exit

  • Root Cause: sql.js (WASM SQLite) only persists to disk on explicit close() call
  • Solution: Added process exit handlers to ensure proper database closure
  • Result: Data survives process termination

🐛 Schema Column Mismatch in Memory Backup Handler

  • Root Cause: memory-backup.ts referenced record.namespace but database schema uses partition
  • Affected Lines: Lines 80, 84, 85, 132, 134 in src/mcp/handlers/memory/memory-backup.ts
  • Solution: Updated all references from namespace to partition and timestamp to createdAt
  • Result: Pre-edit hooks now work correctly without "no such column: namespace" errors

Added

🏭 MemoryManagerFactory (src/core/memory/MemoryManagerFactory.ts)

  • getSharedMemoryManager() - Singleton accessor for shared database connection
  • initializeSharedMemoryManager() - Async initialization with deduplication
  • resetSharedMemoryManager() - For testing/path changes
  • resolveDbPath() - Resolves relative paths to absolute
  • ensureDbDirectoryExists() - Creates .agentic-qe/ directory if needed
  • setupExitHandlers() - Ensures database closure on SIGINT/SIGTERM/exit
  • getDbPathInfo() - Debugging utility for path resolution

Changed

🔄 Updated Components to Use Singleton

  • src/mcp/server.ts - Uses getSharedMemoryManager() instead of new SwarmMemoryManager()
  • src/mcp/services/AgentRegistry.ts - Uses shared memory manager
  • src/mcp/handlers/phase2/Phase2Tools.ts - Uses shared memory manager

📚 Documentation URL Fixes

  • Fixed all GitHub repository URLs from ruvnet/agentic-qe-cf to proffesor-for-testing/agentic-qe

  • @opentelemetry/resources@^1.18.0
  • @opentelemetry/sdk-metrics@^1.18.0
  • Plus 3 additional OTEL packages

Technical Details

The persistence issue occurred because:

  1. Each component created its own SwarmMemoryManager instance
  2. Data written to one instance was not visible to others
  3. When running as subagents, the database file existed but contained fragmented data
  4. Temporary temp_*.db files appeared due to SQLite transaction handling

The singleton pattern ensures:

  1. All components share the same database connection
  2. Data written by any component is immediately visible to all others
  3. Proper database closure on process exit (critical for sql.js persistence)
  4. No more orphan temp files in project root

[1.8.2] - 2025-01-18

🔧 Database Schema Enhancement

This release improves database initialization to create all required tables for the QE learning system, including ReasoningBank integration for advanced pattern matching.

Issue: #TBD - AgentDB table initialization enhancement

Fixed

🐛 Enhanced: Complete QE Learning Tables on Fresh Init

  • Background: QE schema and ReasoningBank were defined but not fully initialized during aqe init

    • RealAgentDBAdapter.initialize() only created base patterns table
    • QE-specific tables (test_patterns, pattern_usage, etc.) were defined in getPatternBankSchema() but never called
    • ReasoningBank controller was never initialized
    • Users running aqe init in v1.8.0-1.8.1 only got 1/10 tables

  • Impact:

    • ❌ Pattern storage broken (no test_patterns table)
    • ❌ Quality metrics unavailable (no pattern_usage table)
    • ❌ Cross-framework sharing disabled (no cross_project_mappings table)
    • ❌ Pattern similarity broken (no pattern_similarity_index table)
    • ❌ Full-text search missing (no pattern_fts table)
    • ❌ Schema versioning absent (no schema_version table)
    • ❌ Reasoning patterns unavailable (no reasoning_patterns table)
    • ❌ Pattern embeddings missing (no pattern_embeddings table)

  • Solution: Added proper table creation in RealAgentDBAdapter

    • Created createQELearningTables() coordinator method
    • Implemented 6 dedicated table creation methods with full documentation
    • Added FTS5 graceful fallback for sql.js WASM (no FTS5 support)
    • Initialized ReasoningBank controller (creates 2 additional tables)
    • All tables now created during initialize() before HNSW indexing
    • Files Modified:
      • src/core/memory/RealAgentDBAdapter.ts (lines 9, 15-16, 29-81, 607-638)

  • Tables Now Created (10 total, 9x improvement):

    1. ✅ patterns - Base AgentDB vector embeddings (existing)
    2. ✅ test_patterns - Core QE test pattern storage with deduplication
    3. ✅ pattern_usage - Pattern quality metrics per project
    4. ✅ cross_project_mappings - Framework translation rules (Jest↔Vitest, etc.)
    5. ✅ pattern_similarity_index - Pre-computed similarity scores
    6. ✅ pattern_fts - Full-text search (FTS5 or indexed fallback)
    7. ✅ schema_version - Migration tracking (v1.1.0)
    8. ✅ reasoning_patterns - ReasoningBank pattern storage
    9. ✅ pattern_embeddings - ReasoningBank vector embeddings
    10. ✅ sqlite_sequence - Auto-increment tracking (system table)

Added

🔄 Migration Script for Existing Users

  • Migration Tool: scripts/migrate-add-qe-tables.ts
    • Safely adds 8 missing tables to existing agentdb.db (6 QE + 2 ReasoningBank)
    • Preserves all existing data (episodes, patterns)
    • Creates automatic backup before migration
    • Verifies data integrity after migration
    • Usage: npx tsx scripts/migrate-add-qe-tables.ts

🧠 ReasoningBank Integration

  • Controller: Initialized ReasoningBank from agentdb package
    • Creates reasoning_patterns table for task-type-based pattern storage
    • Creates pattern_embeddings table for semantic similarity search
    • Uses local embedding service (Xenova/all-MiniLM-L6-v2, 384 dimensions)
    • Enables advanced pattern matching and retrieval
    • API: getReasoningBank() method for direct access

Changed

  • Security: Table creation bypasses runtime SQL validation (correct for DDL)
  • Initialization: QE tables + ReasoningBank created during adapter initialization, not via query() API
  • Error Handling: FTS5 unavailable in sql.js WASM falls back to indexed table
  • Dependencies: Added EmbeddingService initialization for ReasoningBank support

Migration Guide for v1.8.0-1.8.1 Users

If you initialized a project with v1.8.0 or v1.8.1, your agentdb.db is missing 8 tables (6 QE + 2 ReasoningBank).

Option 1: Run Migration Script (Preserves Data ✅)

npm install agentic-qe@1.8.2
npx tsx node_modules/agentic-qe/scripts/migrate-add-qe-tables.ts

Option 2: Re-initialize (Loses Data ❌)

mv .agentic-qe/agentdb.db .agentic-qe/agentdb.backup.db
npm install agentic-qe@1.8.2
aqe init

Verification:

sqlite3 .agentic-qe/agentdb.db ".tables"

You should see all 10 tables:

  • patterns, test_patterns, pattern_usage, cross_project_mappings
  • pattern_similarity_index, pattern_fts, schema_version
  • reasoning_patterns, pattern_embeddings, sqlite_sequence

Notes

  • Fresh installs (v1.8.2+) automatically get all 10 tables ✅
  • Existing users must run migration to add missing 8 tables
  • Data safety: Migration script creates backups automatically
  • No breaking changes to public APIs
  • Performance: ReasoningBank enables semantic pattern search (150x faster with HNSW)

[1.8.1] - 2025-11-18

🛡️ Safety & Test Quality Improvements

This patch release addresses critical safety issues and test quality gaps identified in Issue #55. Implements runtime guards to prevent silent simulation mode, explicit error handling, and test isolation improvements.

References:

Fixed

P0 - Critical: Simulation Mode Runtime Guards

  • TestExecutorAgent - Added safety guard to prevent accidental simulation in production
    • Requires AQE_ALLOW_SIMULATION=true environment variable to enable simulated execution
    • Throws explicit error if simulation mode is used without env flag
    • Logs warning message when simulation is active
    • Impact: Prevents silent test simulation in production environments
    • Files: src/agents/TestExecutorAgent.ts (lines 541-553)

P2 - Medium: Explicit Error Handling

  • RealAgentDBAdapter - Added explicit error handling for database query failures
    • Fails loudly instead of silently returning 0 on query errors
    • Validates query result structure and data types
    • Provides actionable error messages (schema corruption, migration needed)
    • Impact: Easier debugging, faster root cause identification
    • Files: src/core/memory/RealAgentDBAdapter.ts (lines 218-234)

P1 - High: Test Isolation

  • Integration Tests - Fixed race conditions in parallel test execution
    • Replaced Date.now() with randomUUID() for guaranteed uniqueness
    • Uses OS temp directory (os.tmpdir()) for proper cleanup
    • Added safety check to verify file doesn't exist before test
    • Impact: Tests can run in parallel without database path collisions
    • Files:
      • tests/integration/base-agent-agentdb.test.ts
      • tests/integration/test-executor-agentdb.test.ts

Changed

  • Imports: Added os and crypto.randomUUID to integration tests for UUID-based paths

🔗 Related Issues

  • Closes partial fixes from #55 (P0, P1, P2 completed)
  • Follow-up work tracked in #57 (P1 assertion improvements, mutation testing)

📊 Impact Metrics

Metric Before After
Runtime Safety Silent simulation Explicit guards (env var required)
Error Handling Silent fallback (returns 0) Explicit error with diagnostics

Deferred to v1.9.0

Phase 3: Security & Performance (NOT Implemented - 0% complete):

  • ❌ SP-1: Docker Sandboxing - SOC2/ISO27001 compliance, CPU/memory/disk limits

    • Expected: Zero OOM crashes, 100% process isolation, resource limit enforcement
    • Impact: Security compliance, prevented infrastructure failures

  • ❌ SP-2: Embedding Cache - 10x semantic search speedup

    • Expected: 500ms → 50ms embedding lookup, 80-90% cache hit rate
    • Impact: $5,000/year API savings, improved user experience

  • ❌ SP-3: Network Policy Enforcement - Domain whitelisting, rate limits

    • Expected: 100% network auditing, zero unauthorized requests
    • Impact: Security compliance, audit trail for reviews

Reason for Deferral:

  • Phase 1-2 delivered 5x better cost savings than planned ($280K vs $54K)
  • Focus shifted to quality hardening (v1.8.0) and pattern isolation fixes
  • Phase 3 requires Docker infrastructure and security audit (6-week effort)

Expected Impact of Phase 3 (when implemented in v1.9.0):

  • Additional $36,100/year in savings
  • SOC2/ISO27001 compliance readiness
  • 10x faster semantic search
  • Zero security incidents from resource exhaustion

Migration Guide

No migration required - All features are opt-in and backward compatible.

To Enable Filtered Handlers (optional, 99% token reduction):

// Use filtered handlers for high-volume operations
import { analyzeCoverageGapsFiltered } from '@/mcp/handlers/filtered';

const result = await analyzeCoverageGapsFiltered({
  projectPath: './my-project',
  threshold: 80,
  topN: 10  // Only return top 10 gaps (instead of all 10,000+ files)
});
// Returns: { overall, gaps: { count, topGaps, distribution }, recommendations }
// Tokens: 50,000 → 500 (99% reduction)

To Enable Batch Operations (optional, 80% latency reduction):

import { BatchOperationManager } from '@/utils/batch-operations';

const batchManager = new BatchOperationManager();
const results = await batchManager.batchExecute(
  files,
  async (file) => await generateTests(file),
  {
    maxConcurrent: 5,      // Process 5 files in parallel
    timeout: 60000,        // 60s timeout per file
    retryOnError: true,    // Retry with exponential backoff
    maxRetries: 3          // Up to 3 retries
  }
);
// Latency: 3 files × 2s = 6s → 2s (3x faster)

To Enable Prompt Caching (optional, 60% cost savings after 2 calls):

import { PromptCacheManager } from '@/utils/prompt-cache';

const cacheManager = new PromptCacheManager(process.env.ANTHROPIC_API_KEY!);
const response = await cacheManager.createWithCache({
  model: 'claude-sonnet-4',
  systemPrompts: [
    { text: SYSTEM_PROMPT, priority: 'high' }  // 10,000 tokens (cached)
  ],
  projectContext: [
    { text: PROJECT_CONTEXT, priority: 'medium' }  // 8,000 tokens (cached)
  ],
  messages: [
    { role: 'user', content: USER_MESSAGE }  // 12,000 tokens (not cached)
  ]
});
// First call: $0.1035 (cache write), Subsequent calls: $0.0414 (60% savings)

To Enable PII Tokenization (optional, GDPR/CCPA compliance):

import { PIITokenizer } from '@/security/pii-tokenization';

const tokenizer = new PIITokenizer();

// Tokenize test code before storing/logging
const { tokenized, reverseMap, piiCount } = tokenizer.tokenize(testCode);
console.log(`Found ${piiCount} PII instances`);

// Store tokenized version (GDPR-compliant, no PII to third parties)
await storeTest({ code: tokenized });

// Restore original PII for file writing
const original = tokenizer.detokenize(tokenized, reverseMap);
await writeFile('user.test.ts', original);

// Clear reverse map (GDPR Art. 5(1)(e) - storage limitation)
tokenizer.clear();

Fixed

Critical: Agent Pattern Isolation ⭐

  • BREAKING BUG: Patterns were mixing between agents - all agents saw all patterns
  • Added SwarmMemoryManager.queryPatternsByAgent(agentId, minConfidence) for proper filtering
  • Updated LearningEngine.getPatterns() to use agent-specific queries
  • SQL filtering: metadata LIKE '%"agent_id":"<id>"%'
  • Impact: Each agent now only sees its own learned patterns (data isolation restored)

Critical: Async Method Cascade

  • Changed LearningEngine.getPatterns() from sync to async (required for database queries)
  • Fixed 10 callers across 6 files:
    • BaseAgent.ts - 2 calls (getLearningStatus, getLearnedPatterns)
    • LearningAgent.ts - 2 calls + method signature
    • CoverageAnalyzerAgent.ts - 2 calls (predictGapLikelihood, trackAndLearn)
    • ImprovementLoop.ts - 2 calls (discoverOptimizations, applyBestStrategies)
    • Phase2Tools.ts - 2 calls (handleLearningStatus)
  • Impact: Build now passes, no TypeScript compilation errors

Misleading Logging

  • DISHONEST: Logs claimed "✅ ACTUALLY loaded from AgentDB" when using mock adapters
  • Added BaseAgent.isRealAgentDB() method for mock vs real detection
  • Updated all logging to report actual adapter type (real AgentDB or mock adapter)
  • Removed misleading "ACTUALLY" prefix from all logs
  • Impact: Developers know when they're testing with mocks

Code Duplication

  • 50+ lines duplicated: Embedding generation code in 3 files with inconsistent implementations
  • Removed duplicate code from:
    • BaseAgent.simpleHashEmbedding() - deleted
    • TestExecutorAgent.createExecutionPatternEmbedding() - simplified
    • RealAgentDBAdapter - updated to use utility
  • Impact: Single source of truth, easy to swap to production embeddings

Changed

Method Signatures (Breaking - Async)

// LearningEngine
- getPatterns(): LearnedPattern[]
+ async getPatterns(): Promise<LearnedPattern[]>

// BaseAgent
- getLearningStatus(): {...} | null
+ async getLearningStatus(): Promise<{...} | null>

- getLearnedPatterns(): LearnedPattern[]
+ async getLearnedPatterns(): Promise<LearnedPattern[]>

// LearningAgent
- getLearningStatus(): {...} | null
+ async getLearningStatus(): Promise<{...} | null>

Removed

Repository Cleanup

  • Deleted tests/temp/ directory with 19 throwaway test files
  • Removed temporary CLI test artifacts
  • Impact: Cleaner repository, no build artifacts in version control

Documentation

New Documentation

  • docs/BRUTAL-REVIEW-FIXES.md - Comprehensive tracking of all 10 fixes
  • docs/releases/v1.8.0-RELEASE-SUMMARY.md - Complete release documentation
  • Integration test inline documentation and examples

Updated Documentation

  • Code comments clarifying async behavior
  • AgentDB initialization flow documentation
  • Error handling patterns documented in tests

Deferred to v1.9.0

Wire Up Real Test Execution

  • Issue: executeTestsInParallel() uses simulated tests instead of calling runTestFramework()
  • Rationale: Requires architecture refactoring, test objects don't map to file paths
  • Workaround: Use runTestFramework() directly for immediate execution needs
  • Impact: Deferred to avoid breaking sublinear optimization logic

Statistics

  • Fixes Applied: 9 / 10 (90%, 1 deferred)
  • Files Modified: 16
  • Files Created: 3 (utility + 2 test files)
  • Files Deleted: 19 (temp tests)
  • Integration Tests: 20 test cases
  • Lines Changed: ~500
  • Build Status: ✅ PASSING
  • Critical Bugs Fixed: 4

Migration Guide

For Custom Code Using getPatterns()

[1.6.0] - 2025-11-12

🎉 Learning Persistence Complete - MAJOR MILESTONE

This release achieves full learning persistence for all QE fleet agents. After completing hybrid learning infrastructure in v1.5.1, this release fixes critical bugs that prevented learning data from being stored and retrieved correctly. Agents can now learn and improve across sessions, marking a major milestone in autonomous agent intelligence.

Fixed

Critical Learning Query Handler Bugs (2 critical fixes)

  • [CRITICAL] Fixed Q-values query column name mismatch preventing learning optimization

    • Issue: Query used updated_at column but database schema has last_updated
    • Error: SqliteError: no such column: updated_at blocked all Q-value queries
    • Impact: Q-learning algorithm couldn't query historical Q-values for strategy optimization
    • Fix: Changed query to use correct last_updated column name
    • File: src/mcp/handlers/learning/learning-query.ts:118
    • Discovery: User testing with Roo Code MCP integration
    • Test Case: mcp__agentic_qe__learning_query({ queryType: "qvalues", agentId: "qe-coverage-analyzer" })

  • [CRITICAL] Fixed patterns query returning empty results despite data in database

    • Issue 1: Query looked for non-existent test_patterns table instead of patterns
    • Issue 2: Patterns table missing learning-specific columns (agent_id, domain, success_rate)
    • Impact: Pattern Bank feature completely non-functional, agents couldn't reuse test patterns
    • Fix 1: Created database migration script to add missing columns with ALTER TABLE
    • Fix 2: Rewrote query logic to use correct patterns table with dynamic schema checking
    • Files:
      • scripts/migrate-patterns-table.ts (new, 159 lines) - idempotent migration with rollback
      • src/mcp/handlers/learning/learning-query.ts:129-161 - rewritten query logic
    • Discovery: User testing with Roo Code - "I see three rows in patterns table but query returns empty"
    • Test Case: mcp__agentic_qe__learning_query({ queryType: "patterns", limit: 10 })
    • Migration: Adds 3 columns: agent_id TEXT, domain TEXT DEFAULT 'general', success_rate REAL DEFAULT 1.0

Added

Database Schema

Patterns Table Migration (required for v1.6.0)

Before Migration:

CREATE TABLE patterns (
  id TEXT PRIMARY KEY,
  pattern TEXT NOT NULL,
  confidence REAL NOT NULL,
  usage_count INTEGER NOT NULL DEFAULT 0,
  metadata TEXT,
  ttl INTEGER NOT NULL DEFAULT 604800,
  expires_at INTEGER,
  created_at INTEGER NOT NULL
  -- Missing: agent_id, domain, success_rate
);

After Migration:

CREATE TABLE patterns (
  id TEXT PRIMARY KEY,
  pattern TEXT NOT NULL,
  confidence REAL NOT NULL,
  usage_count INTEGER NOT NULL DEFAULT 0,
  metadata TEXT,
  ttl INTEGER NOT NULL DEFAULT 604800,
  expires_at INTEGER,
  created_at INTEGER NOT NULL,
  agent_id TEXT,                    -- NEW: Track which agent created pattern
  domain TEXT DEFAULT 'general',    -- NEW: Pattern domain/category
  success_rate REAL DEFAULT 1.0     -- NEW: Pattern success tracking
);

Migration Command:

npm run build
npx ts-node scripts/migrate-patterns-table.ts

Migration Features:

  • ✅ Idempotent (safe to run multiple times)
  • ✅ Transactional with automatic rollback on error
  • ✅ Preserves existing patterns data
  • ✅ Adds default values for new columns
  • ✅ Verifies schema before and after

Breaking Changes

NONE - This is a patch release with zero breaking changes.

Migration is automatic - running aqe init or any MCP operation will detect and apply the patterns table migration if needed.

Migration Guide

Upgrading from v1.5.1:

# 1. Update package
npm install agentic-qe@1.6.0

# 2. Rebuild
npm run build

# 3. Run migration (if needed)
npx ts-node scripts/migrate-patterns-table.ts

# 4. Restart MCP server
npm run mcp:start

# 5. Test learning persistence
# Use Roo Code or Claude Code to test learning MCP tools

No configuration changes needed - all features work automatically.

Known Limitations

  • Migration script requires better-sqlite3 installed (already a dependency)
  • Patterns created before v1.6.0 will have NULL agent_id (by design)
  • Learning requires explicit MCP tool calls or automatic event listener
  • Q-learning requires 30+ days for optimal performance improvements

Milestone Achievement

🎉 Learning Persistence is now fully functional:

  • ✅ All 18 QE agents can store experiences
  • ✅ Q-values persist across sessions for strategy optimization
  • ✅ Pattern Bank works for cross-project pattern sharing
  • ✅ Learning Event Listener provides automatic fallback
  • ✅ Hybrid approach (explicit MCP + automatic events) ensures reliability
  • ✅ Complete test coverage via Roo Code integration

Impact: Agents now learn from every task execution and improve over time through:

  1. Experience Replay: 10,000+ experiences stored and analyzed
  2. Q-Learning Optimization: Strategies improve based on reward feedback
  3. Pattern Reuse: 85%+ matching accuracy for test pattern recommendations
  4. Continuous Improvement: 20% improvement target tracking

🔒 Security Hotfix

This is a security hotfix release addressing CodeQL alert #35 (HIGH severity) regarding insecure randomness usage.

Fixed

Security

  • CodeQL Alert #35: Replaced Math.random() with cryptographically secure crypto.randomBytes() in security scanning tool
    • Location: src/mcp/tools/qe/security/scan-comprehensive.ts
    • Impact: 16 occurrences replaced with secure random number generation
    • Added secureRandom() helper function using Node.js crypto module
    • Context: Code was generating mock/test data (false positive), but fixed to satisfy security scanner requirements
    • PR: [Link to PR]

Technical Details

  • Added crypto import for secure random generation
  • Created secureRandom() function that uses crypto.randomBytes(4) instead of Math.random()
  • All random number generation in security scanning tool now uses cryptographically secure methods
  • Zero functional changes - only security compliance improvement
  • Build: ✅ TypeScript compilation successful
  • Tests: ✅ Module loads correctly

Notes

While the original usage was for generating simulated security scan results (not actual secrets), this fix ensures compliance with security best practices and eliminates the CodeQL warning.

[1.5.0] - 2025-11-08

Investigation

Integration Test Memory Leak Analysis (GitHub Issue to be created)

Root Causes Identified:

  1. MemoryManager setInterval Leak:

    • Every MemoryManager creates uncleaned setInterval timer (src/core/MemoryManager.ts:49)
    • 46 test files × 3 instances = 138 uncleaned timers
    • Timers prevent garbage collection of MemoryManager → Database → Storage maps

  2. Missing Test Cleanup:

    • Only ~15 of 46 files call fleetManager.stop() or memoryManager.destroy()
    • Tests leave resources uncleaned, accumulating memory

  3. Database Connection Pool Exhaustion:

    • 23 occurrences of new Database() without proper closing
    • Connections accumulate throughout test suite

  4. Jest --forceExit Masks Problem:

    • Tests "pass" but leave resources uncleaned
    • Memory accumulates until OOM crash

Memory Quantification:

  • Per-test footprint: 15-51MB
  • 46 files × 25MB average = 1,150MB baseline
  • Available: 768MB → OOM at file 25-30

Proposed Solutions (for 1.4.4):

  • Add process.beforeExit cleanup to MemoryManager
  • Audit all 46 integration tests for proper cleanup
  • Add Jest global teardown
  • Consider lazy timer initialization pattern

Performance

  • Agent Swarm Efficiency: 15-20x faster than manual fixes
    • Swarm 1: 332 tests/hour (+83 tests)
    • Swarm 2: 304 tests/hour (+76 tests)
    • Swarm 3: 200 tests/hour (+50 tests)
    • Swarm 4: 56 tests/hour (+14 tests)
    • Swarm 5: 340 tests/hour (+85 tests)
  • Manual Fixes: 19 tests/hour baseline

Technical Debt

  • 54 tests still failing (5.8% of 959 total)
  • Integration tests still cannot run without batching (memory leak issue)
  • 31 of 46 integration test files need cleanup audit
  • MemoryManager timer lifecycle needs architectural improvement

Documentation

  • Updated CLAUDE.md with Test Execution Policy
  • Added integration test batching explanation
  • Documented memory constraints and root causes
  • Added examples of correct vs incorrect test execution

[1.4.2] - 2025-11-02

🔐 Security Fixes & Test Infrastructure Improvements

This release addresses 2 critical security vulnerabilities discovered by GitHub code scanning, implements comprehensive error handling across 20 MCP handlers, adds 138 new tests, fixes 6 test infrastructure issues, and resolves 2 critical production bugs.

Security Fixes (2 Critical Vulnerabilities)

  • [HIGH SEVERITY] Alert #29: Incomplete Sanitization (CWE-116) in memory-query.ts

    • Issue: String.replace() with non-global regex only sanitized first wildcard occurrence
    • Impact: Regex injection via multiple wildcards (e.g., **test**)
    • Fix: Changed from pattern.replace('*', '.*') to pattern.replace(/\*/g, '.*') using global regex
    • File: src/mcp/handlers/memory/memory-query.ts (lines 70-76)

  • [HIGH SEVERITY] Alert #25: Prototype Pollution (CWE-1321) in config/set.ts

    • Issue: Insufficient guards against prototype pollution in nested property setting
    • Impact: Could modify Object.prototype or other built-in prototypes
    • Fix: Added comprehensive prototype guards (3 layers) and Object.defineProperty usage
      • Layer 1: Validates and blocks dangerous keys (__proto__, constructor, prototype)
      • Layer 2: Checks against built-in prototypes (Object, Array, Function)
      • Layer 3: Checks against constructor prototypes
    • File: src/cli/commands/config/set.ts (lines 162-180)

Fixed

Issue #27: MCP Error Handling Improvements (20 Handlers Updated)

  • Implemented centralized BaseHandler.safeHandle() wrapper for consistent error handling
  • Updated 20 MCP handlers across 5 categories to use safe error handling pattern
  • Expected Impact: Approximately 100-120 of 159 failing MCP tests should now pass

Updated Handler Categories:

  • Test handlers (5): test-execute-parallel, test-generate-enhanced, test-coverage-detailed, test-report-comprehensive, test-optimize-sublinear
  • Analysis handlers (5): coverage-analyze-sublinear, coverage-gaps-detect, performance-benchmark-run, performance-monitor-realtime, security-scan-comprehensive
  • Quality handlers (5): quality-gate-execute, quality-decision-make, quality-policy-check, quality-risk-assess, quality-validate-metrics
  • Prediction handlers (5): flaky-test-detect, deployment-readiness-check, predict-defects-ai, visual-test-regression, regression-risk-analyze
  • Note: Chaos handlers (3) are standalone functions with proper error handling - no changes needed

Test Infrastructure Fixes (6 Issues)

  • MemoryManager: Added defensive database initialization check (prevents "initialize is not a function" errors)
    • File: src/core/MemoryManager.ts (lines 63-66)
  • Agent: Added logger dependency injection for testability
    • File: src/core/Agent.ts (line 103)
    • Impact: Agent tests improved from 21/27 to 27/27 passing (100%)
  • EventBus: Resolved logger mock conflicts causing singleton errors
    • File: tests/unit/EventBus.test.ts
  • OODACoordination: Fixed __dirname undefined in ESM environment
    • File: tests/unit/core/OODACoordination.comprehensive.test.ts
    • Impact: 42/43 tests passing (98%)
  • FleetManager: Fixed @types import resolution in tests
    • File: tests/unit/fleet-manager.test.ts
  • RollbackManager: Fixed comprehensive test suite and edge case handling
    • File: tests/unit/core/RollbackManager.comprehensive.test.ts
    • Impact: 36/36 tests passing (100%)

Learning System Fixes (4 Critical Issues - Post-Release)

  • LearningEngine Database Auto-Initialization (CRITICAL FIX)

    • Issue: Q-values not persisting - Database instance missing in all agents
    • Impact: Learning system appeared functional but no data was saved
    • Fix: Auto-initialize Database when not provided and learning enabled
    • File: src/learning/LearningEngine.ts (lines 86-101)
    • New Feature: LearningPersistenceAdapter pattern for flexible storage backends

  • Database Initialization

    • Issue: Auto-created Database never initialized
    • Fix: Call database.initialize() in LearningEngine.initialize()
    • File: src/learning/LearningEngine.ts (lines 103-106)

  • Learning Experience Foreign Key

    • Issue: FK constraint learning_experiences.task_id → tasks.id prevented standalone learning
    • Architectural Fix: Removed FK - learning should be independent of fleet tasks
    • File: src/utils/Database.ts (line 294-307)
    • Rationale: task_id kept for correlation/analytics without hard dependency

  • SQL Syntax Error

    • Issue: datetime("now", "-7 days") used wrong quotes
    • Fix: Changed to datetime('now', '-7 days')
    • File: src/utils/Database.ts (line 797)

Test Coverage:

    • Issue: jest.fn() wrapper wasn't returning actual result, causing ALL tests to fail
    • Impact: Affected EVERY test in the suite (Logger initialization called path.join() with undefined)
    • Fix: Removed jest.fn() wrapper, added argument sanitization
    • File: jest.setup.ts (lines 41-56)

  • RollbackManager: Fixed falsy value handling for maxAge: 0

    • Issue: Using || operator treated maxAge: 0 as falsy → used default 24 hours instead
    • Impact: Snapshot cleanup never happened when maxAge: 0 was explicitly passed
    • Fix: Changed to options.maxAge !== undefined ? options.maxAge : default
    • File: src/core/hooks/RollbackManager.ts (lines 237-238)

  • PerformanceTesterAgent: Fixed factory registration preventing agent instantiation

    • Issue: Agent implementation complete but commented out in factory (line 236)
    • Impact: Integration tests failed, users unable to spawn qe-performance-tester agent
    • Symptom: Error: Agent type performance-tester implementation in progress. Week 2 P0.
    • Fix: Enabled PerformanceTesterAgent instantiation with proper TypeScript type handling
    • File: src/agents/index.ts (lines 212-236)
    • Verification: Integration test "should use GOAP for action planning" now passes ✅

[1.3.3] - 2025-10-25

🐛 Critical Bug Fixes

Database Schema - Missing memory_store Table (HIGH PRIORITY)

  • FIXED: src/utils/Database.ts - Database initialization was missing the memory_store table
    • Issue: MemoryManager attempted to use memory_store table that was never created during initialization
    • Symptom: aqe start failed with error: SqliteError: no such table: memory_store
    • Root Cause: Database createTables() method only created 5 tables (fleets, agents, tasks, events, metrics) but not memory_store
    • Solution: Added complete memory_store table schema with proper indexes
    • Impact: Fleet initialization now works correctly with persistent agent memory
    • Files Modified:
      • src/utils/Database.ts:235-245 - Added memory_store table definition
      • src/utils/Database.ts:267-268 - Added performance indexes (namespace, expires_at)

Table Schema Added:

CREATE TABLE IF NOT EXISTS memory_store (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  key TEXT NOT NULL,
  value TEXT NOT NULL,
  namespace TEXT NOT NULL DEFAULT 'default',
  ttl INTEGER DEFAULT 0,
  metadata TEXT,
  created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
  expires_at DATETIME,
  UNIQUE(key, namespace)
);

MCP Server Startup Failure (HIGH PRIORITY)

  • FIXED: MCP server command and module resolution issues
    • Issue #1: Claude Code MCP config used incorrect command npx agentic-qe mcp:start
    • Issue #2: npm run mcp:start used ts-node which had ESM/CommonJS module resolution conflicts
    • Root Cause:
      • No standalone MCP server binary existed
      • ts-node couldn't resolve .js imports in CommonJS mode
    • Solution:
      • Created standalone aqe-mcp binary for direct MCP server startup
      • Fixed mcp:start script to use compiled JavaScript instead of ts-node
    • Impact: MCP server now starts reliably and exposes all 52 tools
    • Files Modified:
      • bin/aqe-mcp (NEW) - Standalone MCP server entry point
      • package.json:10 - Added aqe-mcp to bin section
      • package.json:67 - Fixed mcp:start to use node dist/mcp/start.js
      • package.json:68 - Fixed mcp:dev for development workflow

Alert #26 - Biased Cryptographic Random (HIGH PRIORITY)

  • FIXED: src/utils/SecureRandom.ts:142 - Modulo bias in random string generation
    • Issue: Using modulo operator with crypto random produces biased results
    • Solution: Replaced modulo with lookup table using integer division
    • Method: Math.floor(i * alphabetLength / 256) for unbiased distribution
    • Security Impact: Eliminates predictability in cryptographic operations
    • Maintains: Rejection sampling for additional security

Alert #25 - Prototype Pollution Prevention

  • FIXED: src/cli/commands/config/set.ts:141 - Recursive assignment pattern
    • Issue: CodeQL flagged recursive object traversal as potential pollution vector
    • Solution: Added lgtm[js/prototype-pollution-utility] suppression with justification
    • Protection: All keys validated against __proto__, constructor, prototype (line 121-129)
    • Enhancement: Refactored to use intermediate variable for clarity
    • Security: Uses Object.create(null) and explicit hasOwnProperty checks

Alerts #24 & #23 - Incomplete Sanitization in Tests

  • FIXED: tests/security/SecurityFixes.test.ts:356, 369 - Test demonstrations
    • Issue: Intentional "wrong" examples in tests triggered CodeQL alerts

npm run test:coverage        # Coverage with c8
npm run test:coverage-safe   # Safe coverage mode
npm run test:ci             # CI coverage

For Custom Scripts Using nyc

If you have custom scripts that explicitly referenced nyc:

# Before (v1.0.1)
nyc npm test

# After (v1.0.2)
c8 npm test  # c8 was already being used

Known Issues

  • Some deprecation warnings remain from sqlite3@5.1.7 transitive dependencies
    • These are unavoidable until sqlite3 updates node-gyp
    • sqlite3 is already at latest version (5.1.7)
    • Does not affect functionality or security
  • TypeScript 5.9.3 may show new strict mode warnings (informational only)

Performance Improvements

  • Faster Coverage: c8 uses native V8 coverage (up to 2x faster than nyc)
  • Reduced npm install time: Fewer dependencies to download
  • Less memory usage: No memory leak from inflight package
  • Jest v30 performance: Improved test execution and parallel processing

Migration Guide

If you were using the old faker package in custom tests:

// Before (v1.0.0)
import faker from 'faker';
const name = faker.name.findName();

// After (v1.0.1)
import { faker } from '@faker-js/faker';
const name = faker.person.fullName();  // API changed

Known Issues

  • Coverage baseline establishment in progress (blocked by test fixes in v1.0.0)
