API and Boundary Patterns

API and boundary patterns for advanced Java systems: gateway, BFF, anti-corruption layer, DTO, mapper, contract compatibility, idempotency, pagination, errors, versioning, observability, and strangler migration.

Security and Authorization Patterns

Security and authorization patterns for advanced Java systems: RBAC, ABAC, ReBAC, policy objects, PDP/PEP/PIP/PAP, tenant boundary, ownership guard, capability pattern, auditability, workflow authorization, testing, and anti-patterns.

Observability and Diagnostics Patterns

Observability and diagnostics patterns for advanced Java systems: telemetry contract, structured logs, metrics, traces, correlation, causality, forensic timelines, workflow diagnostics, signal quality, cardinality control, and production debugging.

Testing Patterns for Patterned Systems

Testing patterns for advanced Java systems: test strategy, characterization tests, contract tests, property tests, fixture builders, test doubles, integration tests, Testcontainers, workflow tests, event tests, observability tests, and anti-patterns.

Concurrency Testing Patterns

Concurrency testing patterns for advanced Java systems: interleaving risk, race-oriented tests, jcstress-style litmus tests, deterministic scheduling, stress harnesses, liveness tests, timeout tests, cancellation tests, virtual-thread tests, and production-grade concurrency review.

Performance Patterns

Performance patterns for advanced Java systems: measurement discipline, latency/throughput mental models, batching, pooling, allocation control, locality, contention reduction, cache behavior, JMH benchmarking, JFR profiling, GC-aware design, backpressure, and production performance review.

Modularity, Plugin, and Extension Patterns

Modularity, plugin, and extension patterns for advanced Java systems: package boundaries, JPMS, ServiceLoader, ports and adapters, extension registries, plugin lifecycle, class loading, versioning, architectural fitness functions, and production-grade extension governance.

Refactoring to Patterns

Refactoring to patterns for advanced Java systems: safe seams, characterization tests, branch by abstraction, strangler fig, parallel run, expand-contract migration, extracting policy, replacing conditionals, modularizing legacy code, and making pattern adoption incremental and reversible.
