 - State: Codex reference start screen and Makelore Code with two remembered local projects but no active project.
 - Viewport: implementation CSS viewport 1280 x 800 at device scale factor 1. The source is 908 x 835 pixels with unknown capture density. For full-view comparison, the source was aspect-fit onto a 1280 x 800 white canvas and the implementation remained at its native 1280 x 800 size. The focused comparison uses a 400-pixel-tall lower crop from each normalized content region.
 
 **Findings**
 
 - No actionable P0, P1, or P2 differences remain after applying the user's correction.
-- Fonts and typography: the M hero keeps the reference's restrained system-sans hierarchy and single-line display copy. The CTA, section label, project names, and recency metadata form a clear descending hierarchy without crowding or truncation at the verified viewport.
+- Fonts and typography: the M hero keeps the reference's restrained system-sans hierarchy and single-line display copy. The CTA, project names, and recency metadata form a clear descending hierarchy without crowding or truncation at the verified viewport.
 - Spacing and layout rhythm: the hero retains generous white space. The standalone CTA is visually separated from the existing-project row, and fixed-width cards create a true horizontal browsing pattern without increasing page height as the catalog grows.
 - Colors and visual tokens: the CTA uses the existing Makelore brand orange and the cards use existing neutral surface tokens, preserving the single light product system and one-accent discipline.
 - Image quality and asset fidelity: the hero uses the repository's existing vector Makelore M asset. Project cards use the product's installed icon library; no placeholder image, CSS drawing, or reconstructed logo is present.
-- Copy and content: `新增项目`, `已有项目`, and `选择一个项目继续` state the two available paths directly. Project cards use real project names and last-opened timestamps from the local catalog.
+- Copy and content: `新增项目` remains the only action label above the card rail. The redundant `已有项目` heading and `选择一个项目继续` helper are absent; project cards themselves use real project names and last-opened timestamps from the local catalog.
 - Interaction and accessibility: the CTA opens the existing creation dialog; each card has a project-specific accessible name, keyboard focus treatment, pressed feedback, horizontal overflow, and routes through the Sidebar's existing validated project-entry behavior.

 - Pass 1: the user identified a P1 interaction-model mismatch: the lower surface looked like a default conversation box and omitted horizontally arranged existing projects.
 - Fix: replaced the composer-shaped starter with a standalone `新增项目` CTA; added a horizontal, overflow-safe row backed by the real project catalog; connected card clicks to the existing Sidebar entry path; added unit and Electron coverage.
 - Pass 2: the revised full-view and focused comparisons show the corrected CTA/card hierarchy with no remaining actionable P0/P1/P2 findings.
+- Pass 3: removed the visible project-section heading and helper copy at the user's request. The fresh screenshot and focused comparison confirm that the CTA now leads directly into the unchanged horizontal card rail.
