 Tier 2 returns `inferred_idle` after `idleSilenceMs` without output. A sleeping or network-blocked command can therefore look ready. When a prompt marker was already seen, Tier 2 waits a further `handoffGraceMs` so a bash foreground handoff that lands on the silence boundary still settles as the exact `stdin_read` attribution instead of the weaker inference; the grace is a deployment-owned config field validated to cover at least one `pollIntervalMs`, because a grace shorter than the poll period cannot contain a single readiness poll and so cannot change any outcome. It bounds only sends that saw a marker, so its cost is the interactive return latency of that one case rather than every send. Tier 3 returns `timeout` after `timeoutMs` so a foreground tool call cannot hold the agent indefinitely. The result preserves the distinction; callers may wait through `ctx.tasks`, signal the foreground group, or inspect from another session.

+Once a send settles under any tier, `PtySendOperation.append` stops accepting output, so later child output no longer reaches that settled operation; it still reaches the scrollback, and any send that is active when it arrives. A test that waits for a marker on the operation it started must therefore set `idleSilenceMs` and `timeoutMs` above the child's own startup latency; interpreter startup on a loaded macOS runner otherwise ends the send before the marker is printed.

 `node-pty` data notifications feed one terminal parser. Parser carry state handles control sequences and a trailing carriage return split across callbacks, so a divided CRLF produces one newline rather than a pagination-changing blank line. The implementation normalizes line-oriented output, but it does not promise correct interaction with a full-screen application.
