`worker-start --model <id>` previously passed any id straight to the agent launch, so a typo or a retired id produced a terminal that died on startup with no explanation from Orca. Ask the host that will actually run the worker. `resolveWorkerLaunchModelAuthority` reuses the probe the native chat model picker already uses (`discoverRuntimeCommitMessageModels`), which routes local / WSL / SSH from the worktree selector, so the set `worker-start` accepts is the set the picker lists. Three limits keep the gate honest: - It refuses only when the authority's `source` is `live` — the host's CLI actually answered. A seed fallback (probe failed, timed out, or fell back to Orca's own list) accepts the id and lets the agent CLI report: loss of contact is never evidence that a model does not exist there (`docs/reference/ssh-execution-boundary.md`). - Strictness follows `discoveredModelsReplaceSeed`. Claude and `discoveredModelsAreAuthoritative` catalogs replace the seed, so their lists are complete and may refuse. Codex, Gemini and Cursor only extend the seed — their lists depend on the account and are not exhaustive — so they are not probed at all and refuse nothing. - Effort validation stays the catalog's, unchanged. A probe reports membership only, so its generic level list can never narrow a seeded model's menu. The probe is cached per executing host (`local` / `wsl:<distro>` / `ssh:<id>`) rather than per caller, since one machine's CLI list is one fact; failures are never cached, and a dispatch that gives up on its 10s budget leaves the probe running to fill the cache for the next one. The rejection names the agent, the refused id, and the sorted ids the host listed — never a built-in list presented as authoritative.

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.
