In the boring sidebar, threads inside a project folder did not move when you sent a message. The newest thread you talked to could sit at the bottom of its folder.

Now each folder lists its threads by the last message the user sent, most recent at the top. This reuses sortWorkingThreadsBySend, which the Working shelf already uses. Agent and wake messages do not move a thread. Drag reorder was already off inside folders, and the default sidebar order does not change.

Before (main)	After

Both captures show the same data. Alpha, Bravo, and Charlie were started in that order, then the user sent a new message to Alpha.

Proof: in the dev app with Replay threads, I sent a user message to Alpha from the composer. Alpha moved to the top. With the fix reverted, it stayed at the bottom. vp run check:changed passes.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Boring-mode folders now automatically place threads with the latest user message first; other sidebar modes are unchanged. A human must confirm this change to the folders’ default ordering behavior.

Walkthrough

When project folders are active, the sidebar orders active threads by the user’s latest message. Otherwise, it retains the existing working-shelf return ordering or default sidebar ordering.

Full details: Title check

Explanation

The title names the core change: threads in boring sidebar project folders are now ordered by the user's latest message. It follows the conventional commit format with a fix(web) scope and stays within the scope of the changeset, which updates Sidebar.tsx to pass sortActiveBySend. The title is concise and specific.

Full details: Description check

Explanation

The description covers the problem, the change, and verification. It states the problem (threads in a folder did not move after the user sent a message), the fix (folders sort by last user message, reusing sortWorkingThreadsBySend), and the unchanged behavior (drag reorder off in folders, default order unchanged). It includes before/after screenshots and a manual verification with a revert check, so the UI verification requirement is met. The template's Scope and approval section is missing: there is no linked triaged issue or maintainer-approved discussion, and no explanation of why this small fix qualifies without one. The description also omits the model and harness line, though it names Claude Opus 5.5 in Claude Code, which partly covers the agent disclosure. The Problem and Change headings are not labeled as template sections; the content is present but uses a different structure.

Resolution

Add a Scope and approval section. Link the triaged bug issue or the maintainer-approved discussion, including the approval comment. If no issue exists, explain why this very small, focused fix of an obvious bug qualifies without prior approval. Restructure the description under the template headings (Problem, Change, Scope and approval, Verification). Keep the agent disclosure at the end, in the form the template asks for (model and harness).
