Evidence

Public claim	Supporting commits
A live browser beside every agent thread — Open local pages beside chat in a responsive, tabbed browser that Codex and Claude can navigate. Inspect, annotate, draw on, and attach page context without leaving Threadlines.	7fa4712f, 04cc9f91, d8d7c7e4
An inbox built around attention — The redesigned sidebar separates active work from Wrapped threads, keeps blockers and unseen completions visible, and syncs filing and unread state between desktop and phone.	7842e145, 04f4a91b
Stash prompts with their context intact — Save unfinished prompts with attachments and context, switch threads or providers, then restore them later from the composer or with Cmd/Ctrl+S.	d4f7a39d
Inspect delegated work in place — Open Claude and Codex subagent transcripts inside the parent conversation to follow delegated work without breaking your flow.	d0ac9007
Settings now come from the paired computer, and retention rules are applied server-side.	50daa7f5
Browser navigation approvals use clearer controls and readable destination text.	04cc9f91, 2f2f021a
Completed threads keep running terminal status visible, and clean checkouts reset diff stats.	eb1c4a56, b9422241
Local preview discovery now supports IPv6 servers.	570ef9b2
Touch scrolling no longer fights timeline auto-follow.	1fc7ee6c
