## Problem [#21789](https://git.cafe/pingdotgg/t3code/issues/21789): below 768 CSS px, closing the sidebar sheet unmounted the thread list and its window keyboard listener. With focus in the conversation, Ctrl/Cmd+1–9 and Ctrl/Cmd+Shift+[ or ] then left the current thread unchanged; opening the sheet restored navigation. ## Change Keep the narrow sidebar contents mounted while the sheet is closed. Preserve the floating toggle through closing and responsive layout changes, and discard hidden list measurements so reopening cannot animate rows from zero positions. ## Scope and approval Fixes #21789 Triaged bug via the automated issue flow. Web and Electron share this sidebar; native mobile uses a separate UI. No server, contract, provider, or persistence changes. ## Verification Focused verification: `vp test run src/components/Sidebar.logic.test.ts src/components/Sidebar.drag.test.ts` from `apps/web`: 97 passed. Targeted lint on both production files and web typecheck passed. Capture proof covers listener lifetime, real layout, focus, and animation behavior that these unit tests do not mount. ### Evidence Additional visible effects of retaining the sheet: narrow Settings find/slash shortcuts now open and focus search; sidebar local state survives closing; the first visible reorder after hidden suspension establishes positions without animation.

Each pair below has a representative full-surface table; the complete accepted comparison set is in the table appendix. The original archive also contains a supplemental web I10 take with contaminated relative timestamps (before Alpha/Gamma 4m, after 2h); that take is excluded from matching-fixture proof. The matched native Electron I10 pair below is the authoritative 639 px comparison. Stills supplement the recordings. Diff0 is the full absolute RGB difference at zero threshold, amplified ×8; DiffT marks any channel difference >16/255. No masks/crops. SHA row applies to every comparison. Pixel counts, unamplified zero masks and complete input/focus logs are in the linked archive. Decoded video frames are labeled.

desktop-R2-controlled-closing — 390 CSS px, dark Real Escape starts the actual CSS closing animation while CDP Animation playbackRate=0. The logged animation has duration200ms,currentTime0 before viewport768→390; resume rate1; external toggle opens/closes successfully on both sides. This deliberately controls animation time to make the unfinished-close state deterministic. Baseline also passes because it predates the keepMounted flag regression.

[Rebuilt surface](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/78444adeba2bf39c/rebuild-closed.png), [unmasked amplified diff](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/638acc82904897ff/rebuild-closed-diff-x8.png), [metrics](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/fa8c98d9bf03a25b/rebuild-metrics.json). ### Limits R2 uses the real 200 ms CSS close animation with its clock paused before crossing the breakpoint, then resumes it. Natural wall-clock crossing within 200 ms was not verified. The first visible reorder after hidden geometry is discarded establishes a new baseline without animation; the R1 trace does not prove identical reorder motion. No native sidebar menu item exists in this build. macOS Cmd and Windows Electron were not run; native iOS/Android use a separate sidebar and are unaffected. Hosted/relay/tunnel and provider permutations were not exercised; this changes no transport or provider code. Retaining the hidden sidebar keeps its state and subscriptions alive, as at wide widths; no exhaustive performance profile was run. Web MP4s fully decode but emit FFmpeg duplicate/nonmonotonic timestamp warnings; seeking and driver timestamp annotations are approximate. Original recordings are preserved. Electron WebMs do not emit those warnings.
