## What changed
Add `Client::list_threads` with cursor pagination, page limits, sorting, and originator filtering for unarchived threads. Return thread snapshots, optional read states, and forward and backward cursors while preserving server order and duplicate entries.
Allow stored thread snapshots to contain empty session IDs and model providers while retaining nonempty requirements for activation. Preserve the original snapshot protobuf bytes.
## Testing
Add fixture tests for pagination requests, default query encoding, snapshot and read-state preservation, legacy empty metadata, invalid responses, and activation validation.

## What changed
Add `Client::prewarm_default_thread` to prepare an ordinary coding thread in the default managed cloud environment, with optional model and provider selection. Return the thread identity and resolved settings as `ThreadActivation` without a separate activation RPC, preserving unknown thread protobuf fields.
Send prewarm requests once without automatic retries or cleanup, and document that a failed response can leave a prepared thread whose identity the caller did not receive.
## Testing
Add coverage for default and explicit model/provider requests, resolved settings and native thread metadata preservation, and rejection of responses missing sandbox policy.

## What changed
Add `Client::activate` to load a cloud thread through `UpdateConfig`, sending only the thread ID and `exclude_turns=true`. Return serializable resolved settings, thread metadata, and history cursors while leaving turns for separate pagination. Preserve the original thread protobuf, including unknown fields.
Validate required fields and thread identity, reject unsupported security policies, and redact sensitive activation data in debug output. Treat activation as a mutation that is never retried, with uncertain outcomes reported through `MutationError::OutcomeUnknown`.
## Testing
Add coverage for activation request encoding, settings and metadata preservation, serialization, compatibility defaults, unsupported policies, debug redaction, invalid input rejection, and explicit successful gRPC trailers.

## Why
`Attach` delivers live events only. Clients also need access to stored turn metadata and item content.
## What changed
- Add `Client::list_turns` and `Client::list_items` using native gRPC history endpoints, with optional turn filtering for items.
- Expose page limits, sort order, access mode, and forward/backward cursors. Each call returns one page in server order without automatic pagination or retries.
- Preserve raw response and row payloads alongside typed summaries and item timestamps. Retain unknown item variants and command sources without typed summaries.
- Document cursor reuse and history/live overlap: history pages do not provide an atomic boundary with `Attach`, and coordinated reconciliation still requires caller-managed state.
## Testing
Add wire-fixture tests for request encoding, explicit pagination, raw payload preservation, unknown data, malformed rows, empty pages, RPC errors without retries, and diagnostic redaction.

## What changed
Add `codex-cloud-client`, a reusable Rust client for `ThreadService.Resume` and live `ThreadService.Attach` over HTTP/2. Callers supply the native gRPC origin, bearer token, account ID, and `HttpClientFactory`.
- Reuse shared proxy, custom CA, and network policy handling for HTTPS. Reject redirects and allow plaintext HTTP only on direct loopback with unrestricted, unmanaged policy.
- Preserve notification and server-request protobuf payloads as opaque bytes and expose native gRPC status details while redacting credentials, payloads, and error details from diagnostics.
- Bound resume and attach setup to 150 seconds without retrying requests or imposing an idle deadline on live streams. Attach ends on its first error and provides no history or automatic reconnect.
- Select Rustls in `HttpClientBuilder::http2_prior_knowledge()` so HTTPS advertises `h2` through ALPN.
Include a standalone attach example and documentation of admission semantics and stream behavior.
## Testing
Add HTTP/2 fixture tests for protobuf framing, authentication metadata, status trailers, event preservation, malformed responses, stream cancellation, redirect rejection, and diagnostic redaction. Add checks for unsafe origins, network policy restrictions, and TLS `h2` advertisement.
