Closes #3106. Adds /api/session/title/regenerate endpoint + session-action menu item. Preserves chronology (touch_updated_at=False), guards read-only and imported sessions, syncs to state.db when Insights sync enabled. Maintainer refinement (Opus SHOULD-FIX): scope the is_imported guard to the regenerate action only instead of broadening the shared _isReadOnlySession() helper, which also gates rename/pin/archive/move/fork. Matches the backend 403 guard. Test updated to assert the scoped shape.
Maintainer fix on stage (browser-test catch): Prism.highlightElement() propagates the language-* class onto the parent <pre>, so previewing a .css file then a .txt file rendered the plain text with CSS grammar. Strip any stale language-* from #previewCode before each render and only call highlightElement when a language was assigned. Adds regression test (tests/test_issue3337_workspace_preview_highlight.py) and bumps the _openSessionActionMenu scan window in test_1466 to cover the new Regenerate-title action lines (#3223).
…load, #3337 uniform code bg, #3223 menu clip fix #3220: redesign generated-image rendering from a permanent bordered card (filename + Open/Download buttons) to a clean inline image with click-to-zoom lightbox + a hover/focus-revealed Download overlay, matching ChatGPT/Claude/ Gemini. Drops redundant Open (lightbox already covers it). Tests updated. #3337: fix two-tone code background — Prism's prism-tomorrow theme styled the parent <pre> gray while the <code> was navy var(--code-bg), so dark theme showed a gray frame around navy code. Override BOTH .preview-code[class*=language-] and its <code> to var(--code-bg) (mirrors the chat code-block fix at .msg-body pre). #3223: fix action-menu clipping — the new Regenerate-title row made the 9-item menu tall enough to overflow the viewport bottom when opened on a top-anchored row at short viewports (e.g. 1280x720). _positionSessionActionMenu now clamps the menu within both viewport edges and caps max-height with scroll when the menu is taller than the viewport.
…keys Opus iter2 SHOULD-FIX (both non-blocking, applied for cleanliness): - esc() the media_download title/aria-label so a future translator's quote can't break out of the attribute (defense-in-depth). - Remove the now-dead media_open key from all 11 locales + the ui.js fallback dict (the Open button was dropped in the clean-image redesign).
…con+label menu Nathan feedback round 2: - #3220: generated images were rendering at the 120x90 upload-thumbnail size (too small for the subject of the message). Now render at natural aspect ratio up to 360px (max-height 360, responsive max-width), lightbox preserved. - #3223: drop the per-item subtitle/description lines from the session action menu — show only icon + label (VS Code / browser / ChatGPT pattern). The description is preserved as a hover tooltip (title=). Makes the menu ~40% shorter, less crowded, and structurally less prone to viewport clipping.
…rlays the image The .msg-artifact-image span was stretching wider than the image (inline-block in a block context filled the line), so the absolutely-positioned download button (right:8px of the wrapper) floated ~240px to the right of the image. Add width:fit-content + max-width so the wrapper hugs the image; the button now correctly overlays the image's top-right corner. line-height:0 removes inline descender gap.
…rop blur) Nathan feedback: the download icon read as 'oddly placed' on dark generated images. Geometry was already correct (8px inset on the image corner) — the issue was low contrast: a flat rgba(0,0,0,.55) button blends into a dark image. Add a subtle 1px white border, soft shadow, and 3px backdrop-blur so the button reads as a clear chip-on-image regardless of the underlying pixels (the standard treatment for on-image controls). CSS-only.

Release FY — v0.51.205 (stage-hi1)
Three contributor feature PRs, deep-reviewed and UX-iterated with maintainer polish. Phase-3 HIGH-tier wave 1.
What's in this release
#3337 — Workspace file-preview syntax highlighting (@mysoul12138)
Prism.js highlighting in the workspace code preview (reuses the Prism already loaded for chat code blocks — no new dependency, degrades to plain text offline). Covers Python/JS/TS/CSS/JSON/SQL/shell/etc.
.cssthen a.txtfile mis-highlighted the plain text) by stripping stalelanguage-*from the<pre>each render + only highlighting when a language is assigned.<pre>a different shade than the inner<code>, producing a two-tone block on dark).#3220 — Generated image rendering (@AJV20)
Generated local images render as a clean, prominent inline image (up to 360px, natural aspect ratio) with click-to-zoom lightbox and a hover/focus-revealed Download button overlaid on the image — matching the ChatGPT/Claude/Gemini pattern. (Reworked from the original card design per maintainer UX review.)
#3223 — Manual session title regeneration (@AJV20, closes #3106)
A "Regenerate title" action in the session menu, generating a fresh title from the saved transcript without reordering the sidebar (preserves chronology) and syncing to state.db when Insights sync is enabled.
