MultiTerminal 2.1.0

Feature release: phone/remote workflow, a proactive worktree janitor with human alerting, and project-scoped task/worktree resolution. No breaking changes — a drop-in upgrade over 2.0.0.

Added

• Ask-Owner remote question flow — new ask_owner MCP tool + POST /api/ask-owner let an agent pose a blocking question that routes to the Owner's phone and waits for the answer, instead of stalling silently when the Owner is away.
• Phone arrival indicators — Permissions and Alerts badges surface pending items on the phone, notifications support read-all, and the gateway returns detailed 400 diagnostics.
• Janitor human alerting — actionable janitor findings are routed to the team-lead inbox, escalated to a severe-tier push, and surfaced at session start, so stranded worktrees and blocked merges get a person's attention.
• Project-scoped pickable tasks — a new pickable endpoint + MCP tool surface the next tickets by project rather than by agent, with reassign-on-claim.
• Installer: opt-in user-global MCP registration (default off) during install (GH#2).
• Task HUD Active / Not-Active tabs with per-tab UX: readability, description tooltips, search, and a sort toggle.

Fixed

• Janitor blind to the .claude/worktrees layout — the stranded-dir scan and Pass-3 orphan removal no longer report a silent false ok/0/0 while real husks sit on disk. WorktreeLayout now derives the repo root for the modern {repoRoot}/.claude/worktrees/{id} layout; underivable parents degrade the scan to partial instead of vanishing; a child-shape gate guards Pass-3 deletes; rootPrefix separators are normalized so forward-slash-registered projects don't drop their own stranded dirs.
• Cross-project task/worktree leakage — active-task and worktree resolution are now project-scoped; an explicit-target guard stops a team lead's active-task worktree from hijacking a New Project launch.
• Push reliability — valid default VAPID subject + BadDeviceToken pruning; the push success ratio no longer misreports after prune.
• Alerts badge unread tracking — rewired to a gateway-native watermark with hardened read-all and a LoadSeen repair that heals a poisoned watermark across restarts.
• HUD Notes delete-confirm popup was clipped invisible by the tab bar — now rendered fixed-position on document.body.
• Terminal document leak on tab close — disposed via ContentRemoved.

Docs & Chore

• README doc quick-links point at the GitHub Pages site (GH#3); .nojekyll added so docs/ serves statically; new "Running from source" troubleshooting FAQ.
• Repo cleanup: removed the dead PromptTreeDocument panel, ephemeral test-artifact docs, a dead TestSpawnForm, knowledge-seed.sql, and 16 orphaned dev-scratch PowerShell scripts.
