Summary

Folded commit previews made a shortened code block look complete, with a closed bottom border and a separate ellipsis. Shortened blocks now fade out toward Show more, making the hidden continuation clear.

Changes

• Fade only blocks whose preview differs from their full code, using the existing full-code copy data.
• Remove the standalone ellipsis after those blocks; keep it for complete blocks followed by hidden prose.
• Keep the horizontal scrollbar outside the fade by masking the code content and decorative background separately.
• Add rendering coverage and update the public knowledge base.

Validation

• composer test:lint — PASS (isolated temporary directory; existing warnings).
• composer test:types — PASS.
• composer test:type-coverage — PASS, 100%.
• bun run test:unit — PASS, 216 tests.
• bunx vp test --config tests/draft-images.config.ts — PASS, 794 tests, including three new cases.
• bun run build — PASS.
• XDEBUG_MODE=coverage php -d memory_limit=-1 vendor/bin/pest --parallel --ci --coverage --exactly=100.0 --passthru-php="'-d' 'memory_limit=-1'" — PASS, 5,195 tests, 28,163 assertions, exactly 100% coverage.
• Copying while folded includes the hidden code. Expanding reveals the full block, removes its fade, and moves keyboard focus to the commit.

Visual evidence

Local fictional demo content. Original before captures use the production base; refreshed after captures add a wide-line fixture to exercise horizontal scrolling. Captured with T3 preview and device tools. Desktop CSS viewport sizes are 1440×900 and 1366×650; T3 scales desktop capture output. Mobile viewport emulation is 390×844. Both themes inspected.

Device verification

iPhone 18 Pro Max simulator, iOS 27, Safari: verified folded fade, touch expansion, wrapping and scrolling beyond the first screen. Browser controls and bottom navigation leave Show more usable. No inputs changed; keyboard verification is inapplicable.

Simulator screenshots below show the refreshed revision. The earlier simulator recording is retained in the original media revision.

Independent review

Sol 6.1, high reasoning, fast service: CODE PASS · VISUAL PASS, no actionable findings, for base 462b07903b58a0aea32018c8e9f869419dbe1ab3, head 81e50624c61024979aa92b461774544aefa926aa.

Limitations

No physical-device testing. Native macOS scrollbar thumb dragging was not verified; horizontal scroll input, wrapping and unmasked scrollbar ownership were verified. Warmed-cache measurements and sampled recording frames were used. Navigation and an unchanged-content polling cycle recorded no layout shifts. One initial-load sample recorded a small shift of 0.0000903; zero CLS is not established for every cache condition or viewport. Intentional expansion shifts with recent input were comparable to the baseline. New-content insertion and removal during polling were not exercised.

Summary by CodeRabbit

• Updates
  • Folded commit previews now fade at the bottom of shortened code blocks and avoid an extra trailing ellipsis when the code block itself is truncated.
  • Code blocks retain their wrapped or unwrapped horizontal overflow behavior within the updated preview layout.
• Documentation
  • Updated the description of folded posts; it no longer states that Show more avoids cutting through code. The 280-character and 8-line folding thresholds remain unchanged.

Walkthrough

Folded commit bodies now apply a bottom mask to shortened code blocks and remove a trailing ellipsis after those blocks. Tests cover shortened previews, hidden prose, and complete bodies. The documentation no longer claims folding avoids cutting through code.

Changes: Folded code-block previews

Layer / File(s)	Summary
Folded code-block preview behavior resources/js/components/commit-body.tsx, resources/js/components/code-block.tsx, tests/Unit/FoldedCommitBody.test.tsx, KNOWLEDGE_BASE.md	When a code block has different full and preview HTML, rendering adds a bottom mask and preview processing removes a trailing ellipsis. The wrapper controls horizontal overflow. Tests cover shortened previews, hidden prose, and complete bodies. The documentation retains the folding threshold and removes the claim that folding avoids cutting through code.

Explanation

Docstring coverage is 50.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 2 functions across 3 files.

Assert the fade in the rendering tests.

This test passes even if CodeBlock stops applying the mask. Assert that the shortened block has the mask classes, and that complete blocks do not.
