 Stage Summary:
 - v7.5 shipped: music links now resolve by download-and-convert — the server runs the operator's command (audio-only, VBR-0 MP3, title preserved), serves the finished file same-origin with full Range support, and the Playing: label shows the video's real title. The three failure classes behind "media resource not suitable" (IP-locked URLs, URL expiry, webm/Opus containers) are gone by construction; bot-wall/stale-extractor self-healing is unchanged, over-long tracks answer honestly, a missing ffmpeg degrades to the legacy proxy, and playlist look-ahead leaves room for conversions.

+Task ID: 33
+Agent: main (Z.ai Code)
+Task: v7.5.1 Link dialog width fix (user request, screenshot-backed): on the operator's VPS deployment the "Stream a music link" dialog rendered with its content stretching past the box — description, input + Load button, RECENT LINKS rows and footer all crossed the right border.
+
+Work Log:
+- Screenshot forensics (drive link → pixel analysis, no guesswork): the user runs the outline base + green accent, so the dialog box is a pure-black rounded rect defined by an emerald-800 border. Measured from pixels: border columns x=716/1203 (487 px ≈ 448 CSS px at 110 % zoom), yet content ran to x≈1247 — Load button and recent rows crossed the right border by ~44 px while the left padding was respected. Text did NOT wrap wrong — the CONTENT COLUMN itself was wider than the box.
+- Reproduced locally (agent-browser, seeded long recent titles): grid-template-columns on DialogContent measured 461.9 px inside the 448 px dialog; every child laid out at 462 px → 39 px past the border. Binary-search by hiding children: the plain recent-links wrapper DIV is the sole culprit; white-space:normal on its title spans drops the track to the perfect 398 px.
+- Root cause: DialogContent is display:grid with an IMPLICIT single column — the track sizes to the widest child's min-content. The recent rows' truncate spans are white-space:nowrap, and Chromium measures a nowrap flex item's FULL text width for the container's min-content (min-w-0 lets the span shrink at layout time but does not zero its min-content contribution through the block→flex chain) — one long saved title ("Bobby Foox — This Is Why We Can't Have Nice Things (Official Music Video)") measured ~462 px > 448 px dialog, blowing the track so EVERY child (not just the rows) laid out past the right border.
+- ui/dialog.tsx + ui/alert-dialog.tsx (shared fix, every dialog app-wide): the implicit column is now pinned to grid-cols-[minmax(0,1fr)] — minimum 0, sized to the free space, so nowrap content can never stretch a dialog past its border again; rows/lists simply truncate/wrap within the box.
+- link-dialog.tsx: sm:max-w-md → sm:max-w-lg (512 px — the library default, comfier for the long description + input row); min-w-0 on the recent-links and playlist containers (direct defense on the measured culprit); break-words on the error text (resolver errors can embed long URLs).
+- version.ts: APP_VERSION 7.5.1 + changelog. lint clean; tsc clean (pre-existing examples/skills only).
+
+E2E (agent-browser, ALL PASS):
+- Seeded the user's exact recent list (two "Bobby Foxx … (Official Music Video)" + 孟婆): dialog 512 px, track exactly 462 px = content box, ZERO overflowing children, long titles now end in "…" inside their rows. VLM on the fixed dialog (outline theme + green accent replicated): no element crosses the border, Load button comfortably inside, description wraps, ellipsis visible.
+- Responsive: 375 px viewport → dialog 343 px, track 293 px, zero overflow, fits viewport with margins.
+- Regression sweep: service-login dialog (most complex remaining dialog) 512 px / 462 px track / zero overflow; simple max-w-sm form dialogs structurally protected by the shared track cap. Test browser localStorage cleaned afterwards.
+
+Stage Summary:
+- v7.5.1 shipped: the Link dialog (and every other dialog) can no longer be stretched past its border by long unbreakable content — the shared dialog column is capped at the available width, the Link dialog is comfortably wider (512 px), long recent/playlist titles truncate with ellipsis, and error text with embedded URLs wraps. Deploy note: no server changes, pure client fix.
