Apply one absolute deadline across response headers, streaming raw bodies, page creation, and later readiness waits. Report the active timeout phase without extending the caller's budget and reject raw documents from Page APIs before an unusable body can stall.
Give CLI fetch failures a stable two-line Error/Reason presentation while retaining full anyhow chains for non-fetch failures, including raw-document page-wait errors.
Split screenshot and screencast capture contracts, publish one shared visual resource generation, and collect CSS image references during the real layout traversal. Add asynchronous publication and multi-session screencast regressions.
Settle renderer command turns against the Page residence that admitted them, while preserving immutable acknowledgements after navigation replaces that Page. Route output fences and post-response continuations through the canonical command context before decoding Input replies. Also isolate scheduler-sensitive runtime tests discovered during full-workspace validation.
