They're inside the existing Projects PRs, plus one small Insider PR that's already merged:

• SDK: https://github.com/OpenHands/software-agent-sdk/pull/6602. The mention commit (1620647) and the verify-map commit with the new

F36.mention

check (f4f7a27) are both on its branch.

• Canvas: https://github.com/OpenHands/OpenHands/pull/19495. There are two commits: mentions open in place (38077cd) and keep working in chat bubbles (92c1c0b).

• Insider: [enyst/insider #23](https://github.com/enyst/insider/pull/23), merged.

The two separate PRs (SDK + Canvas, behind the

conversation_mentions

experimental flag) don't exist yet. As we agreed, I'm holding them until #6609 and #19503 land, since they build on that flag registry.
