Reusable, workspace-shared agent roles for the built-in AI chat. A role is a named persona (system-prompt instructions) + optional model override; a chat is bound to a role at creation and applies it every turn. Backend: - migration 20260620T120000: ai_agent_roles table + ai_chats.role_id (FK ON DELETE SET NULL); hand-merged types into db.d.ts/entity.types.ts (db.d.ts is hand-curated here, full codegen would clobber it). - core/ai-chat/roles: CRUD module. list = any workspace member; create/ update/delete = admin (Manage Settings ability, like ai-settings/mcp). All repo queries scoped by workspace_id; soft-delete (deleted_at). - buildSystemPrompt gains roleInstructions: role REPLACES the persona base (admin prompt / DEFAULT_PROMPT) but SAFETY_FRAMEWORK + context are always still appended. - stream(): role resolved from ai_chats.role_id for existing chats (never the request body -> no per-turn role swap); body.roleId only on creation. Disabled (enabled=false) and soft-deleted roles fall back to universal. - getChatModel(workspaceId, override): role model_config can swap model id / driver; a driver without configured creds throws 503 with a clear message naming the driver+role, resolved BEFORE response hijack. Client: - new-chat role picker (enabled roles only, default Universal assistant), roleId sent only on the first message; role badge (emoji+name) in the chat header and conversation list; admin Agent-roles management section in Settings -> AI (add/edit/delete, MCP-form pattern). Tests: ai-chat.prompt.spec (role layering + safety always present, incl. jailbreak); ai.service.spec (override on unconfigured driver -> 503). Implements docs/ai-agent-roles-plan.md.
