Note

High Risk
Breaking removals (persistent browser delete/types, project URL prefix) plus a large new telemetry surface and org-scoped project routes require consumer updates and careful rollout.

Overview
0.56.0 is an OpenAPI-driven SDK release: new browser telemetry and policy knobs, project API path changes, and removal of deprecated persistent-browser APIs.

Browser telemetry adds client.browsers.telemetry.stream() (SSE on GET /browsers/{id}/telemetry) with a large set of typed events (console, network, page lifecycle, interactions, monitor health). Sessions can pass telemetry on create/update and echo telemetry / chrome_policy on browser responses.

Browsers accept optional chrome_policy on create. Deprecated BrowserPersistence, persistence fields, and client.browsers.delete({ persistent_id }) are removed; use timeouts/profiles and deleteByID instead.

Projects CRUD and limits now call /org/projects (and /org/projects/{id}/limits) instead of /projects. max_persistent_sessions is dropped from project limit types.

Managed auth types can_reauth_reason as a string union with documented affirmative/negative values.

Minor: proxy check docs when a custom url is provided; tsc-multi bumped for Node 26; version 0.56.0 and changelog/metadata only otherwise.

Firetiger deploy monitoring skipped

This PR didn't match the auto-monitor filter configured on your GitHub connection:

Any PR that changes the kernel API. Monitor changes to API endpoints (packages/api/cmd/api/) and Temporal workflows (packages/api/lib/temporal) in the kernel repo

Reason: This is an automated release PR with no direct file changes shown; the filter requires monitoring of specific API endpoint and Temporal workflow file changes, which cannot be verified from this PR metadata alone.

To monitor this PR anyway, reply with @firetiger monitor this.
