Summary

Reverts #7515. A same-session VM Lighthouse A/B shows it made the seeded workspace page slower on desktop: median LCP +72.5 ms (1615.0 -> 1687.5 ms, 6+6 ABBA, all runs quiet). The limit is +40 ms.

Background

#7515 made the status view lazy so the workspace page would stop loading the artifact frame (#7510). The seeded page also loads the right sidebar, and the right sidebar still imports the artifact stack (McpAppFrame.tsx:59 imports a constant from SandboxedArtifactFrame; RightSidebar shares useArtifactInteractions and the viewers). So the frame code still loads, only later: in the right-sidebar wave at about 335-380 ms instead of the early wave at about 150 ms, plus three new shared chunks (33 -> 36 requests, +5.8 KB script). LCP equals TTI in every run, so the later graph end moves LCP.

Details and per-run numbers: #7510 (comment)

Implementation

git revert 47d2e4df7d. ChatPane imports AgentInterfaceStatusView statically again, and the rendererFirstLoad.test.ts guard added by #7515 goes too (on main the guard is false again, so it would fail). #7510 is reopened; the next attempt fixes the sidebar importers first and gates on the seeded page's real request list plus a VM A/B.

Validation

• make static-check passes locally.
• Expected VM result after merge: seeded desktop back to the cf7b78bd55 level (about 1604-1615 ms), 33 requests.

Risks

Low. This restores the code that was on main until 19:43Z today. The status view (experiment-gated) behaves the same either way.

Perf owner: merge record for #7521.

1. Final commit 352a95c256 (exact inverse of 47d2e4df7d; no later main commit touches its two files). All checks pass, including Required. Codex code and security reviews completed with no findings (👍). 0 threads. Codex rounds: 1.
2. Reason: VM A/B runs-ab/20261025T195728Z, seeded desktop median LCP +72.5 ms with 🤖 perf: load the agent interface status view only with the view #7515 (limit +40). Cause and next plan: 🤖 perf: the workspace page loads the artifact frame chunk since #7455 (seeded desktop LCP +40 ms) #7510 issuecomment-6402552008.
3. Independent advisor (clean context): ready with tracked follow-ups. Follow-up = 🤖 perf: the workspace page loads the artifact frame chunk since #7455 (seeded desktop LCP +40 ms) #7510 (owner: perf owner; next attempt gates on the seeded page's request list and a VM A/B before merge).
