 - AgentQueryOptions supports `provider` field (defaults to 'claude', flows Rust -> sidecar), `provider_config` blob (Rust passes through as serde_json::Value), `permission_mode` (defaults to 'bypassPermissions'), `setting_sources` (defaults to ['user', 'project']), `system_prompt`, `model`, `claude_config_dir` (for multi-account), `additional_directories`, `worktree_name` (when set, passed as `extraArgs: { worktree: name }` to SDK → `--worktree <name>` CLI flag), `extra_env` (HashMap<String,String>, injected into sidecar process env; used for BTMSG_AGENT_ID).
 - Multi-agent orchestration: Tier 1 (management agents: Manager, Architect, Tester, Reviewer) defined in groups.json `agents[]`, converted to ProjectConfig via `agentToProject()`, rendered as full ProjectBoxes. Tier 2 (project agents) are regular ProjectConfig entries. Both tiers get system prompts. Tier 1 prompt built by `generateAgentPrompt()` (utils/agent-prompts.ts): 7 sections (Identity, Environment, Team, btmsg docs, bttask docs, Custom context, Workflow). Tier 2 gets optional `project.systemPrompt` as custom context. BTMSG_AGENT_ID env var injected for Tier 1 agents only (enables btmsg/bttask CLI usage). Periodic re-injection: AgentSession runs 1-hour timer, sends context refresh prompt when agent is idle (autoPrompt → AgentPane → startQuery with resume=true).
 - bttask kanban: Rust bttask.rs module reads/writes tasks table in shared btmsg.db (~/. local/share/bterminal/btmsg.db). 6 operations: list_tasks, create_task, update_task_status, delete_task, add_comment, task_comments. Frontend: TaskBoardTab.svelte (kanban 5 columns, 5s poll). CLI `bttask` tool gives agents direct access; Manager has full CRUD, other roles have read-only + comments.
+- btmsg/bttask SQLite conventions: Both btmsg.rs and bttask.rs open shared btmsg.db with WAL mode + 5s busy_timeout (concurrent access from Python CLIs + Rust backend). All queries use named column access (`row.get("column_name")`) — never positional indices. Rust structs use `#[serde(rename_all = "camelCase")]`; TypeScript interfaces MUST match camelCase wire format. TestingTab uses `convertFileSrc()` for Tauri 2.x asset URLs (not `asset://localhost/`).
 - ArchitectureTab: PlantUML diagram viewer/editor. Stores .puml files in `.architecture/` project dir. Renders via plantuml.com server using ~h hex encoding (no Java dependency). 4 templates: Class, Sequence, State, Component. Editor + SVG preview toggle.
 - TestingTab: Dual-mode component (mode='selenium'|'tests'). Selenium: watches `.selenium/screenshots/` for PNG/JPG, displays in gallery with session log, 3s poll. Tests: discovers files in standard dirs (tests/, test/, spec/, __tests__/, e2e/), shows content.
 - Worktree isolation (S-1 Phase 3): Per-project `useWorktrees` toggle in SettingsTab. When enabled, AgentPane passes `worktree_name=sessionId` in queryAgent(). Agent runs in `<repo>/.claude/worktrees/<sessionId>/`. CWD-based detection: `utils/worktree-detection.ts` `detectWorktreeFromCwd()` matches `.claude/worktrees/`, `.codex/worktrees/`, `.cursor/worktrees/` patterns on init events → calls `setSessionWorktree()` for conflict suppression. Dual detection: CWD-based (primary, from init event) + tool_call-based `extractWorktreePath()` (subagent fallback).
