# R06 — Close and recording cleanup

Environment: fs-50; Linux 6.8.0-117-generic x86_64; Node v26.12.1; Playwright 1.60.0; Chrome Headless Shell 157.0.8103.38; isolated dev:server, T3CODE_DEV_SEED=0, fresh per-checkout SQLite; synthetic Fx fixture; RPC/MCP over loopback; UTC timestamps.

Scripted interaction (same inputs on both revisions; generated ids differ): Start recording A before holding appearance; after expiry, close A, list remaining tabs, and act on B. Observe encoder and page closure.

What differed: Close bypasses the retained action queue and removes the recording tab on both revisions; actual encoder/page/context close milestones are captured.

## C1 steps and timestamps
