Changelog — Execution Module

All notable changes to the Execution module are documented here. The format is based on Keep a Changelog.

[Unreleased]

Added

• src/execution/AUDIT.md, src/execution/CHANGELOG.md, src/execution/FUTURE_ENHANCEMENTS.md, src/execution/MODULE_GAPS.md, src/execution/PERFORMANCE_EXPECTATIONS.md, src/execution/PRODUCTION_REQUIREMENTS.md, and src/execution/SECURITY.md: restored the required execution governance document set.

Changed

• src/execution/README.md, src/execution/ARCHITECTURE.md, and src/execution/ROADMAP.md: aligned the execution narrative with the live bounded scheduler and fixed-size central-queue worker pool implementation.
• include/execution/query_scheduler.h and include/execution/thread_pool_manager.h: refreshed Doxygen comments so the public API documents current behavior, reserved configuration fields, and shutdown/error semantics.

[1.0.0] — 2026-08-08

Added

• include/execution/query_scheduler.h, src/execution/query_scheduler.cpp: initial deadline-ordered query scheduler with queue-depth backpressure, low-priority shedding, and SLA-completion metrics.
• include/execution/thread_pool_manager.h, src/execution/thread_pool_manager.cpp: initial bounded worker-pool implementation with central dispatch queue, graceful shutdown, and exception accounting.
• tests/integration/test_load_balancing.cpp, tests/integration/test_resource_pooling.cpp: focused scheduler and thread-pool regression coverage.

[1.1.0] — 2026-09-16

Added

• tests/execution/test_execution_highcardinality_stress.cpp: Wave-D stress coverage for high-cardinality dispatch and queue contention.
• benchmarks/execution/bench_execution_dedicated_gates.cpp: dedicated execution benchmark gates for enqueue, dequeue, drain, and dispatch throughput.

Changed

• src/server/http_server.cpp and include/server/http_server.h: instantiate and tear down the execution scheduler and thread pool under THEMIS_EXECUTION_MODULE.
