+# SLO-Preserving Endpoint Split (fs_006)
+
+## Objective
+Split monolithic endpoint into read/write paths while preserving latency and memory budgets and updating observability dashboards.
+
+## Language & Library Constraints
+- Primary language: cpp
+- Available libraries: boost, nlohmann/json, fmt
+- Prefer explicit use of selected library APIs in task execution contracts.
+
+## Required Artifacts
+- server/api/*.cpp
+- server/read_path/*
+- server/write_path/*
+- observability/dashboards/*
+- perf_test_plan.md
+
+## Acceptance
+- Generate deterministic taskitems with strict execution contracts.
+- Include selected library and preferred APIs per task where applicable.
