Orchestration resolves every worker through a terminal handle and a pane key backed by a live PTY. A session created directly as structured has neither, so it was not refused by orchestration — it was invisible. A coordinator could not start one, address one, or receive `worker_done` from one. Add a second authority source rather than a parameter channel. A registry maps a session id to the same three facts the PTY path supplies — a bearer handle, a pane key and a host scope — and the four runtime getters consult it before giving up on `ptysById`. `orchestration.send` and `verifyDispatchCapability` are untouched: authority stays host-derived and the CLI still cannot assert who it is. PTY handles short-circuit on the handle prefix, so the terminal path is unchanged. Mail travels as a session turn instead of as bytes, on a sibling lane that keeps the PTY lane's outstanding-run, waiter, reserved-type and batch rules. Orchestration's database stays the source of truth; the send is best-effort, exactly as the byte write is, and mail is consumed only on a proven-accepted dispatch. Delivery waits for the session to be between turns, because one provider refuses a mid-turn start outright and the other cannot acknowledge one inside the ack window. Security properties, each pinned by test: the pane key's leaf is random and persisted rather than derived, since `check` is identity-gated and accepts a caller-supplied pane key; the handle is a random bearer token; the child env carries no pane key, which would otherwise flow into hook pipelines that assume a PTY leaf; hook attestation stays closed for structured handles; and process continuity comes from record lineage, never the runtime fence, which the host bumps during its own crash recovery. Also remove the "Orchestration paused" notice, which gated only on dispatch status and rendered over bridge chat where orchestration always worked; refuse the implicit-sender fallback when a worktree has more than one candidate leaf instead of guessing; and collapse the archive kinds to one named type with a compile-time assertion that the capture set cannot drift ahead of the storable set.

Features
Also in the box:
- Quick open — Search across worktrees, files, agents, commands, and repo context without leaving your flow.
- Account switcher & usage tracking — See Claude and Codex usage and rate-limit resets, and hot-swap accounts without re-logging in.
- Rich repo previews — Preview Markdown, images, PDFs, and repo docs in the workspace.
- Computer Use — Let agents operate desktop apps and visible UI when a workflow needs real interaction.
- Notifications and unread state — Know when an agent finishes or needs attention, then mark threads unread to come back later.
- And many, many more — we ship daily, so this list is perpetually behind. The changelog is the real feature list.
