+## [Unreleased]
+
+### Changed
+
+- isolate the optional PolkaVM runtime in `truapi-polkavm-host`; keep the base
+  server and browser asset distribution independent, and pin cooperative update
+  deadlines, multi-touch input, and image clipboard output (#540)
+
+### Added
+
+- Generate a transport-neutral `no_std` Rust client with typed request,
+  subscription, result-subscription, and host-initiated Worker subscription
+  codecs.
+- Generate complete App, Widget, Worker, and Worker-only method catalogs from
+  the canonical protocol schema.
+
+### Fixed
+
+- return a decode error instead of trapping when subscription helpers receive a
+  request descriptor
+
 ## [0.13.1] - 2026-09-02

+The PolkaVM runtime implementation, wire crates, browser package, and ABI
+contract live in `paritytech/polkavm-host-runtime`. The base `truapi-server`
+must remain PolkaVM-free. Native integrations use the optional
+`truapi-polkavm-host` composition crate; browser integrations consume
+`@parity/polkavm-browser-runtime` directly. Never copy or export browser assets
+from this repository.

 ### Crate + binding invariants
 
 - `truapi` is canonical; runtime crates re-export rather than redefine. New

 1. The protocol is defined as Rust traits in [`rust/crates/truapi/`](rust/crates/truapi/), with each method tagged `#[wire(id = N)]` for a stable byte-level dispatch table. Every method's doc comment must carry a ` ```ts ` example, which codegen extracts into the playground's EXAMPLE tab; the build fails if any method is missing one.

+2. `truapi-codegen` reads rustdoc JSON for that crate and generates the TypeScript client, Rust host dispatcher, and the transport-neutral `no_std` Rust client. The Rust client exports typed method markers plus complete App, Widget, Worker, and Worker-only catalogs from the same wire schema.
+3. Higher-level SDKs wrap the generated client; each runtime provides only its native frame transport. Browser products use `MessagePort` (or `postMessage` in iframe mode), while sandboxed runtimes such as PolkaVM supply explicit host imports.
 4. The host decodes the frame, dispatches to the matching trait method, encodes the response, and ships it back.
 
 Wire ids are append-only: existing ids never change, so deployed products stay compatible across protocol revisions. Discriminant 255 is permanently reserved for a correlated protocol error, allowing either peer to reject API messages introduced after it was released instead of leaving the caller pending.

+# Add host-mediated pointer capture to TrUAPI
+
+## Status
+
+Parked prototype note. Do not start an RFC or implementation from this draft
+yet. Current hosts capture non-Tri2D surfaces after a primary click, which is
+sufficient for the existing game prototypes. Revisit only after prototypes
+demonstrate that products need runtime capture/release control beyond the
+host's click-to-capture and Escape-to-release policy.
+
+## Summary
+
+Pointer lock is host functionality. A product should request and release it through TrUAPI rather than declaring a separate `relative-pointer` feature in its manifest. The host owns the application surface, enforces user activation, calls the platform pointer-lock API, and reports lifecycle changes. High-frequency movement remains on the bounded device-input data path.
+
+This separates three concerns:
+
+- The App manifest declares ordinary `pointer` input support.
+- TrUAPI controls whether pointer lock is free, armed, or captured.
+- Request denial is a call error, and an older host reports the protocol's
+  standard unsupported-method error.
+- The runtime input ABI delivers absolute positions while free and relative
+  deltas while captured.
+
+## Motivation
+
+Graphics profile is not a pointer policy. Some framebuffer and WebGPU products are first-person games that need unbounded relative motion; others are cursor-driven tools that must leave the system pointer free. Defaulting all non-Tri2D surfaces to pointer lock surprises cursor-driven products, while a static manifest feature cannot express when a mixed menu/game product wants capture.
+
+Pointer lock also cannot be delegated to sandboxed product code. Browser and native hosts own the trusted surface and must preserve an unconditional escape path.
+
+## Proposed control plane
+
+Names are placeholders for the RFC:
+
+```ts
+input.pointerCapture.request(): Promise<Result<\"armed\" | \"captured\", PointerCaptureError>>
+
+input.pointerCapture.release(): Promise<Result<void, PointerCaptureError>>
+
+input.pointerCapture.subscribe(): Subscription<
+  \"free\" | \"armed\" | \"captured\"
+>
+```
+
+The subscription follows the existing `theme.subscribe()` and
+`locale.subscribe()` convention: it emits the current state immediately and
+then every transition. A separate `status()` request would duplicate the first
+subscription item.
+
+A browser generally cannot honor `request()` immediately because pointer lock
+requires a transient user activation. In that case `request()` returns
+`armed`; the host acquires lock on the next eligible primary click on the
+requesting product's active surface.
+
+`release()` is idempotent and always permitted. Escape always releases capture
+and is consumed by the host for that transition rather than forwarded to the
+product as a key press.
+
+`denied` is a request error rather than a durable capture state: after denial
+the surface remains `free`. A host that predates these methods already has a
+standard answer—the TrUAPI protocol-error frame for an unknown discriminant—so
+`unsupported` does not belong in the domain state enum.
+
+## Fit with the existing TrUAPI architecture
+
+The API should be a small `Input` method group, backed by an optional
+`PointerCaptureHost` platform callback. The TrUAPI server is product-scoped, so
+the callback already runs in the identity and lifecycle context of the calling
+product. Web, desktop, and other surface-owning hosts implement the callback;
+CLI or non-pointer hosts omit it and receive the existing `Unsupported`
+behavior.
+
+This should not be added to `HostDevicePermissionRequest`. RFC 0002 defines
+device permission decisions as indefinitely persisted grants or denials, often
+paired with an operating-system permission. Pointer lock is transient surface
+state, requires a current user gesture, and must always be releasable. A future
+host policy may gate the request, but the first API does not need a persisted
+permission.
+
+The RFC must allocate new append-only wire discriminants for request, release,
+and the subscription lifecycle. Existing discriminants cannot be reused.
+
+## Input data plane
+
+Pointer movement does not travel through TrUAPI. The existing bounded runtime input channel remains the data plane:
+
+- Free pointer: event type `5`, absolute canvas `x`/`y`.
+- Captured pointer: event type `6`, signed relative `dx`/`dy`.
+- Buttons: event types `3` and `4` in either state.
+
+Hosts should discard the first cursor-warp sample after lock acquisition, reject non-finite or implausible discontinuities, and coalesce high-rate deltas to the runtime's bounded update cadence.
+
+The browser operation is Pointer Lock (`requestPointerLock()`), not DOM pointer capture (`setPointerCapture()`). DOM pointer capture only preserves event routing during a drag and does not provide an unbounded relative pointer.
+
+## Host invariants
+
+- Pointer lock defaults to off for every graphics profile.
+- Only the product bound to the active verified surface may request capture.
+- Capture requires a real user gesture on that surface.
+- A product cannot suppress Escape release.
+- Losing focus, replacing the product, navigating, or destroying the surface releases capture.
+- Relative events are emitted only while the surface actually owns pointer lock.
+- Request denial and every state transition are observable by the product so it
+  can stop mouse-look or present fallback controls.
+- Hosts that predate the API return TrUAPI's standard unsupported-method error;
+  products decide whether keyboard, touch, or controller input is an acceptable
+  fallback.
+
+## Manifest relationship
+
+No separate `relative-pointer` manifest feature is required. TrUAPI already
+provides generic unsupported-method handling, the runtime request expresses
+current intent, and the host remains the authority.
+
+A future RFC may revisit install-time metadata if hosts need to warn that a product cannot function without pointer lock. Such metadata would describe compatibility or user experience; it would not replace runtime request/release control.
+
+## Future user policy
+
+A host may eventually expose a per-product policy such as `Ask`, `Allow`, or `Block`, plus a global `Never allow pointer lock` setting. This is intentionally deferred.
+
+If added, the setting should authorize or deny product requests; it should not force an arbitrary cursor-driven product into relative mode. The policy should be scoped to a verified product identity, show a visible capture indicator, and preserve Escape as an unconditional release path.
+
+## Revisit criteria
+
+Keep the existing host behavior while prototypes mature. Promote this note to
+an RFC only when at least one real product demonstrates a concrete need such
+as:
+
+- a cursor-driven framebuffer or WebGPU surface that must never capture;
+- a mixed menu/game product that must release and reacquire capture without
+  relying on Escape and a new click;
+- a cross-host inconsistency that cannot be fixed as host policy;
+- a product that needs to observe capture denial or loss to provide a usable
+  fallback.
+
+If one of those cases appears, the RFC should specify request, release, the
+immediate state subscription, wire ids, user-gesture semantics, and errors.
+Only after that should the shared Rust core, host callbacks, Epoca, Dotli, and
+products be changed.
+
+## Unresolved questions
+
+- Whether `request()` should be a one-shot request or remain armed across Escape release until the product cancels it.
+- Whether capture permission persists per product, per publisher, per artifact version, or only for the current session.
+- Whether native hosts need a distinct result for operating-system policy denial.
+- Whether products need an optional install-time declaration that pointer lock is essential rather than merely supported.
+- Whether a host should expose a standard visual indicator or leave presentation to each host implementation.
