[3.3.0] - 2026-11-09

Milestone v3.3.0 "Beyond Herdr": always-on foreground RPC, first-class agent/pane/workspace CLI, semantic agent introspection, worktree swarm DAG runner, Mission Control HUD, and hierarchical D:(W,S,Y,P) coordinates (Phases 65–71, 71 phases total).

Added

• Phase 65 — Architectural Guardrails (GUARD-01..03): SignalablePid newtype for all signaling, PaneTransport enum (Local/Remote/None), and focus-and-raise mouse isolation.
• Phase 66 — Always-On Foreground RPC & Instance Discovery (LIVE-01..04): 0600 RPC socket in TUI and GUI, child PTY env injection (BILTERM_SOCKET, BILTERM_INSTANCE_PID, BILTERM_WORKSPACE_ID, BILTERM_PANE_ID) with from_pane attribution, multi-instance registry with --instance <pid|all>, OIA [RPC:LIVE] and :rpc.
• Phase 67 — Agent/Pane/Workspace CLI (HERDR-01..04): w<N>:p<M> and semantic selectors (@claude, @idle, @blocked, ...), bilterm agent|pane|workspace subcommands, smart prompt injection (bracketed paste aware), zero-polling server-side agent wait.
• Phase 68 — Semantic Introspection & Context Bus (BEYOND-01..04): agent.last_turn, permission-gate interceptor with approve/deny, per-pane FIFO prompt queue, cross-agent bilterm context bus.
• Phase 69 — Worktree Swarm & DAG Runner (SWARM-01..04): atomic worktree agent spawner, :swarm run <plan.toml> DAG waves, diff/merge/clean, self-healing verify_cmd retry loop.
• Phase 70 — Mission Control HUD & Time-Travel (HUD-01..04): :agents hud, per-turn replay scrubber, stall/loop watchdog, full UNI-R01 parity.
• Phase 71 — Hierarchical Coordinates (COORD-01..04): 5-level D:(W,S,Y,P) addressing, universal parser/resolver, title-bar coordinate badge, :coords, coords.resolve/coords.format RPC, bilterm_coords_resolve MCP tool, [coords] config, tmux pane ids.
