 ## Host boundary
@@ -14,57 +14,9 @@ Built-in features of the desktop and web app, each behind the SDK in `src/sdk/`.
 - Host code must not name an extension or know its internals: no extension ids, command ids, DOM selectors, or stored key formats. When the host needs something from extensions, add a generic, documented field to the SDK (for example `PanelTab.file`, `Command.featured`, `Command.section`).
 - Accepted exceptions: the built-in lists, the keybind rename map in `packages/app/src/settings/keybinds/migration.ts`, the legacy `type: "browser"` comment decode in `packages/app/src/composer/schema.ts` (drafts and message metadata written before extension notes), and the crash page's use of the updater contract.
 
-## Lifetimes
-
-An instance lives from `setup` until it is disabled, reloaded, removed, or its window closes. A reload can land at any `await`, so code that outlives a tick must prove it still belongs to the live instance.
-
-- Everything registered through `ctx` (contributions, services, remotes, menu items, surfaces) is withdrawn by the host when the instance goes away. Anything else you start (timers, DOM or remote listeners, subscriptions) needs `ctx.cleanup`. A cleanup registered after disposal runs at once.
-- `setup` may be async. After every `await`, return if `ctx.signal.aborted` before touching state or contributing. Pass `ctx.signal`, or a signal derived from it, to remote calls and long work.
-- Never keep a value from a shorter lifetime in a longer one. Read a server's `client`, `data` and `url` from its live `ServerRef` each time: a restarted or re-authenticated server gets a new controller under the same id. Keep per-session state in a session-scoped store, or in a map keyed by session that you prune.
-- Main: `MainApp.restart(handoff)` keeps the calling extension active until the handoff settles; when it rejects, return to a state the user can retry from.
-
-## Failure is part of the contract
-
-- `ctx.use(Service | Remote)` returns `undefined` while the provider is loading, disabled, failed, or restarting. Every user action must still answer: show an unavailable state (as WSL's "WSL unavailable" does), never a silent `return` or an endless spinner.
-- A remote that goes away is a suspension, not a failure: keep what the user had (for example the browser's tab inventory) and resume when it returns, without a retry timer.
-- A remote call can reject while the event that explains it is still in flight; events and call replies travel on different channels. When main reports an outcome as an event, let the event decide, and treat a rejection as final only for errors main throws before any event (validation, missing endpoint).
-- The host orders remote state for you: an event always wins over an older snapshot. Do not re-fetch state to fix ordering.
-
-## Stored state
-
-- Desktop storage loads over IPC; web storage is synchronous, so a read before load passes every web e2e test and still breaks desktop. Check the store's `ready` accessor before reading values, deriving requests from them, or writing.
-- Moving a stored value goes through `from` (and `from.sessions` for one session's slice of an app key). Keep the old field readable until every user has migrated; never drop user data.
-- `MainStorage` writes reach disk at once; do not batch them yourself.
-
-## Panels and layout
-
-- `Panel.focus(tab, view, { restored })`: `restored` is true only for the selection the side region mounts with (for example after a reload). Run side effects that express user intent, such as switching the file tree's tab, only when it is false.
-- The host selects a fallback tab while the stored one is not listed. If you will restore a tab, keep listing its stored id, with `hidden: true` while its content is not known yet, so the fallback never runs.
-- Map keys stored before extensions with `Panel.legacy`. A `transient` panel's stored keys are dropped once it stops listing them.
-- `Layout.stored(session)` returns your stored tab ids. Layout reads and writes do nothing while `session.location` is undefined (for example after a server re-authenticates), so hold writes, and anything that records them as done such as a mirror of external state, until the location is known.
-- Narrow screens: a plain open switches to the panel's mobile view and closes the dock. Pass `background` when the user stays where they are (a palette pick, a composer chip) or the agent opened the tab, and `select` to append and select without replacing the preview.
-
-## Solid
-
-Read [You Might Not Need an Effect](https://react.dev/learn/you-might-not-need-an-effect) and [Solid.js Best Practices](https://www.brenelz.com/posts/solid-js-best-practices/) before writing reactive code here. In short:
-
-- Derive, don't sync. A value computed from other state is a `createMemo` or a plain function, never a `createEffect` that calls a setter. Never mirror state into a second store, signal, or `Map` through an effect.
-- An effect synchronizes with something outside Solid: the DOM, a third-party widget, a native surface, a remote subscription, a chunk preload. Comment what it syncs with when that isn't obvious.
-- Logic caused by a user action belongs in that action's handler, not in an effect that watches the state the action changed. If several handlers share it, call one function from each.
-- Reset state on an identity change by keying the subtree (`<Show keyed>`) or by storing an id and deriving the selection from it. To forget a selection when the user navigates away and back, derive a visit token (`createMemo(on(key, () => ({})))`) and keep the selection only while its token matches. Never reset state in an effect.
-- No effect chains, and no effect that notifies a parent: update everything in the same handler or `batch`.
-- Don't destructure props; read `props.x` so the getter stays reactive (`splitProps` when you must). Call signals when passing them as JSX props. Use `<Show>` and `<For>`, not `&&` and `.map`, in JSX.
-- Use `createStore` for objects and collections, `createSignal` for single values.
-- Async data goes through a resource or a guarded promise that ignores stale results, under the Suspense rules below, never an effect that fetches and then sets.
-
 ## Performance
 
-- `renderer.tsx` loads with the app: `src/renderer.ts` imports every built-in entry eagerly, because the window renders once all of them are active. Keep it small and put heavy UI behind `lazy()`. Preload a chunk with `onIdle(() => void Chunk.preload())` from setup, so it compiles while the app idles (e.g. on Home) instead of when a session first opens. Never import a heavy chunk on the startup path.
-- A `<Suspense>` boundary decides what blanks when something beneath it suspends; it does not stop the suspension. Suspend at most once, on first load, and never after first paint:
-  - Read async data through `.latest`, a store with an explicit `loading` flag, or a resource that resolves once (`packages/app/src/runtime/server/runtime.tsx`, `packages/app/src/providers/connect/controller.ts`). Never read a refetching `resource()` in render: a refetch blanks the nearest boundary, and without one of yours that is the whole session route, which detaches the screen and resets the timeline scroll.
-  - Wrap each `lazy()` component in its own `<Suspense>`, so a chunk that is still loading blanks only your area. Preload it with `onIdle`. If the area can be visible at startup (for example a dock restored open), start the preload in `setup` from the stored state instead, so the first render never enters Suspense and nothing pops in.
-  - Give a fallback the area's size when the area has fixed geometry, so nothing shifts; leave it empty otherwise.
-  - Make a state change that may suspend inside `startTransition`, so the current content stays until the next is ready.
+- Keep `renderer.tsx` small and put heavy UI behind `lazy()`. Preload a chunk with `onIdle(() => void Chunk.preload())` from setup, so it compiles while the app idles (e.g. on Home) instead of when a session first opens. Never import it on the startup path.
 - Return stable objects from `Panel.list` and reactive contributions, so the host never remounts a trigger or a panel.
 - Never add work to timeline rows. The session header slot is the only timeline surface.
