Scope

Covers Unity 6 game and tool development: the MonoBehaviour lifecycle and event-execution order, Unity's own serializer and the prefab/ScriptableObject data model, coroutines and Awaitable, per-frame allocation and the Profiler workflow, the Universal Render Pipeline (SRP Batcher, GPU Resident Drawer, Render Graph, materials and shader compatibility), runtime UI in uGUI and UI Toolkit, built-in 3D physics (fixed timestep, colliders, triggers, layers, queries), assets and memory (Addressables, sprite atlases, texture compression), Editor extension code and domain reload, the DOTS/ECS boundary, the Unity Test Framework, and batch-mode player builds with IL2CPP, managed stripping, licensing and exit codes in CI.

Targets Unity 6 (6000.x). When a project does not state a version, assume Unity 6.3 LTS (6000.3) — the current LTS; Unity 6.6 (6000.6) is the current Update release. Rules that differ across those versions carry an explicit gate. Unity 2022 LTS and earlier are out of scope; so is the Built-in Render Pipeline except where a project is migrating off it.
