How zone-server tells the client a request was refused (equip denied, party invite failed, master creation rejected, etc). Read this BEFORE adding a new `*ErrorSMSG` class or a new denial/error enum for a handler. Triggers on: ErrorSMSG, OperationError, OpError, denial, Denial, sendDenial, refused, error code, SMSG error.

Explains how zone-server's skill catalog (skills.yml), the master skill tree (master_skill_tree.yml), and the Godot client's Attack DB (bestia-client/src/Game/Attack/DB/*.tres) relate to and must stay in sync with each other, including the description -> skills.csv translation pipeline. Read this BEFORE adding/renumbering a skill, changing a master's learnable skill tree, adding/editing a skill description, or investigating why a skill shows up wrong (or not at all) in the client Skills window. Triggers on: skills.yml, master_skill_tree.yml, AttackResource, AttackDB, skill_id, description_key, skills.csv, MasterSkillTreeRegistry, MasterSkillTreeNode, GetSkillsHandler, SkillListSMSG, skill tree, learnable skill, max_level.

Regenerate the C# protobuf client files after editing any .proto file in bnet-messages/src/main/proto/. Use this whenever a .proto message definition changed, before committing — otherwise the Godot client (bestia-client) keeps stale generated code that no longer matches the schema. Triggers on: .proto, protobuf, protoc, Envelope, CMSG, SMSG, bnet-messages, regenerate proto, gen-protobuf.

Explains the bestia-behemoth server architecture — protobuf message contracts (bnet-messages), the Envelope wire format, Netty socket handling, message dispatch/handlers, the ECS (entity/component/system) game loop with parallel "wave" scheduling, the login-server↔zone-server JWT handoff, and the AI module. Read this BEFORE investigating "how does message X travel from client to server", "where does system Y live", "how do I add a new message type", or any other cross-cutting networking/ECS question — it gives file:line pointers so the answer doesn't have to be re-derived from scratch. Triggers on: protobuf, .proto, Envelope, CMSG, SMSG, Netty, socket server, zone-server, login-server, ECS, ecs/core, entity component system, message handler, JWT auth, bnet-messages, ChannelRegistry, World tick, gen-protobuf.
