Description

Failure mode (in the alignment_audit lane):

Unhandled pty write error [Error: EBADF: bad file descriptor, write]

surfaced as a lane failure; passed on rerun.

Observed: #2273 alignment_audit; passed on rerun.

Likely cause: pty fd closed while a write is still in flight during headless-session teardown under load.

Suggested fix: track pty lifecycle (abort pending writes before close) and/or treat post-close write errors as benign in the audit harness.

Contributor guide

Research direction
Investigate the alignment audit CI lane, locate the headless session teardown code, and trace the pty lifecycle to see why write operations can occur after the file descriptor is closed.
