- **Mission Control has no persistence.** A page reload wipes the
aggregate and reseeds from the next `session/list` refresh — the
view is a live overlay, not a store.
- **Artifact preview opens in your default browser.** No embedded
webview, no cloud tunnel; the shell hosts a `127.0.0.1` static
server and drops a card into chat when a new file appears in the
artifact dir.
- **Artifact preview: inline peek in-stream, full view in the browser.**
Each artifact card can expand a low-key inline preview — Markdown
rendered read-only by a tiny dependency-free renderer (`md-mini.js`,
text-node-only, so any raw HTML inside the doc stays literal), and
`.html` framed in a `sandbox="allow-scripts"` iframe pointed at the
existing `127.0.0.1` server. There is still **no embedded webview for
full pages**: the inline frame is a fixed-height peek, and "Open in
browser" remains the path for the real, full-size artifact. Previews
are collapsed by default and lazy (content builds on first expand);
when the artifact server isn't up the `.html` expand falls back to the
open-in-browser action instead of a broken frame.
- **Growth reads jsonl + `session/list`.** A follow-up will migrate to
the `session/list` + `session/events` aggregation so events that
never touch the overlay (pure chat activity) also show up.
