Playwright Foundation

Use when porting Playwright's client RPC architecture (GUID object trees, channel proxies, async emitters, Waiter/Progress cancellation, timeout ladders, typed error round-trips) or its child-process lifecycle kernel (spawn fd layout, graceful-close ladders, signal refcounting, cross-platform tree kill, length-prefixed pipe framing, launch readiness races).

Playwright (microsoft/playwright): Client RPC & Cancellation Foundation

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: playwright; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: d4e1023f6c03a8dced50eb3db88c2217e7c1a86a.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Message dispatch; Object lifecycle; Channel surface; Async context; Event plumbing; Lazy subscriptions; Wait orchestration; Server cancellation.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
