Autonomous build of board card tsk-cpgdhh.

Add LibraryItemCard component per docs/design/library-app.md sections 2-4.
Card shows thumbnail (or placeholder), title, kind badge, media duration,
pipeline status per stage (jobs shape), artifact list (text, transcript,
description, ocr) with preview, link-to-collection action, and a disabled
Download stub until P3. Failure states are always visible -- no silent
empties for missing thumbnails, pipeline stages, artifacts, or errors.

Includes lib/library.ts with types and API client for the library store
(items, artifacts, jobs) and 25 component tests covering pending,
processing, ready, and error states.

100-100: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low value

Item-level preview is repeated for every text artifact.

preview is derived once from item.meta_json (Line 100) but rendered inside the per-artifact loop (Lines 223-231), so multiple text artifacts (e.g. transcript + ocr) all show the same item-level preview. If per-artifact previews are intended, read the preview from art.meta_json instead.

Reuse fetchJson for JSON-returning helpers.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Broken thumbnail fails silently.

When a thumbnail artifact exists but the image fails to load, onError just hides the <img> (Line 157), leaving blank space with no fallback. This contradicts the PR's "visible failure states for missing thumbnails" goal (and the "failure must be visible, never silent" note at Line 167). Consider swapping in the placeholder on error rather than hiding.

source option is declared but never sent.

IngestLibraryOptions.source (Line 130) is never included in the request body — Line 141 only serializes url and title. Either wire it into the payload or drop it from the interface to avoid a silently ignored option.

🔧 Proposed fix (if backend accepts a source field)
-    body: JSON.stringify({ url, title: opts?.title ?? "" }),
+    body: JSON.stringify({ url, title: opts?.title ?? "", source: opts?.source ?? "" }),

desktop/src/components/LibraryItemCard.tsx 53 formatDuration returns empty string for 0 seconds — hides valid data
desktop/src/lib/library.ts 65 listLibraryItems doesn't validate response shape beyond array check

🏆 Best part: The test coverage is genuinely impressive — 25 tests covering pending, processing, ready, and error states with proper fixtures. The component structure is clean and the "failure states always visible" philosophy is baked into the design. I'm almost impressed.

💀 Worst part: The thumbnail src uses a filesystem path (/tmp/thumb.jpg). This is a critical bug that will render thumbnails completely broken in any browser context. The fetchJson helper swallowing all errors silently is a close second — it turns debugging into archaeology.

📊 Overall: Like a beautifully wrapped gift box with a brick inside — the component looks great and tests are thorough, but the thumbnail path bug and silent error swallowing will cause real production pain. Fix the critical issues and this merges clean.

Let me analyze the diff for correctness, security, testing, and style issues:

Analysis of LibraryItemCard.tsx

Correctness Bugs

  1. LibraryItemCard.tsx:176 - onDownload callback never enabled/enabled logic missing: The onDownload prop is accepted but the download button is always disabled (line 176 shows Download (not available yet) with disabled state). The button has no onClick handler to call onDownload. Same for onOpenSource - the button exists (line 253) but only when source_url is set, yet there's no onClick handler calling onOpenSource. This makes the callbacks useless.

  2. LibraryItemCard.tsx:253 - onOpenSource handler missing: The "Open source" button (line 253) renders when source_url exists but has no onClick handler calling onOpenSource. The button is non-functional.

  3. LibraryItemCard.tsx:182 - Thumbnail src uses raw filesystem path: Line 182 uses thumbnailArtifact.path directly as img.src (e.g., /tmp/thumb.jpg). This is a security issue - file system paths should not be exposed directly to <img src>. Should use a blob URL, data URL, or a served endpoint.

  4. LibraryItemCard.tsx:138 - formatDuration bug for 0 seconds: Returns empty string "" for 0 or negative seconds. But the test at line 189 expects "2:00" for duration 120. What about 0 duration? Empty string may cause layout shift or missing label.

  5. LibraryItemCard.tsx:68-70 - parseMeta returns Record<string, unknown> but code accesses .duration, .preview, .error as if they exist: Lines 132-138 do itemMeta.duration, itemMeta.preview, itemMeta.error - these are unsafe accesses on unknown type. Should use type guards or explicit typing.

  6. LibraryItemCard.tsx:188 - Thumbnail alt text uses item.title directly: If title contains quotes or special chars, it could break the alt attribute. Should escape or sanitize.

  7. LibraryItemCard.tsx:244-254 - Source URL button exposes full URL in label: Open source https://youtube.com/watch?v=abc exposes full URL in aria-label which could leak query params/tokens in screen readers.

Security Issues

  1. Line 182: Direct filesystem path in <img src> - potential path traversal or local file exposure if artifact path is user-controlled.

  2. Line 253: Full source URL exposed in aria-label - potential info leak of query parameters.

Missing/Weak Test Cases (LibraryItemCard.test.tsx)

  1. Missing: onDownload callback test - The component accepts onDownload prop but no test verifies it's called when download is clicked (though currently the button is always disabled, so this would fail - see bug fix: security hardening — bind, validation, atomic writes, deploy rollback #1).

  2. Missing: onOpenSource callback test - Component accepts onOpenSource but no test verifies it's called when source button clicked.

  3. Missing: Thumbnail error handling - No test for broken thumbnail image (onError handler).

  4. Missing: Empty artifacts array edge case - Tests pass artifacts array but don't test artifacts=[] vs artifacts=undefined difference (component defaults to []).

  5. Missing: Malformed meta_json - Test at line 344 tests empty {} but not invalid JSON like "{broken" - though parseMeta catches it, no test verifies graceful degradation.

  6. Weak: Duration formatting edge cases - Tests only 120s (2:00). No tests for: 0s, 59s, 3600s (1:00:00), 3661s (1:01:01), negative values.

  7. Missing: onLinkToCollection called with correct item - Test exists (line 242) but only for "done" state. Should test for other states too.

  8. Missing: Download button enabled state - No test verifies download button becomes enabled when artifacts exist (since it's currently always disabled, this is expected to fail until bug fix: security hardening — bind, validation, atomic writes, deploy rollback #1 fixed).

Style Issues

  1. LibraryItemCard.tsx:26-29 - STATUS_COLORS duplicates pending and processing: Both have identical values. Could merge.

  2. LibraryItemCard.tsx:37-38 - JOB_STATE_COLORS.queued uses text-shell-text-tertiary: This class doesn't exist in standard Tailwind - appears to be a custom class that may not exist in the codebase.

  3. LibraryItemCard.tsx:45 - TEXT_ARTIFACT_KINDS array: Could be a const tuple as const for better type inference.

  4. LibraryItemCard.tsx:57 - formatBytes uses Math.log / Math.pow: Could use Math.log10 or bit operations for clarity, but functional.

  5. LibraryItemCard.tsx:132-138 - Inline type assertions: Number(itemMeta.duration), String(itemMeta.preview) - should use proper type guards.

  6. LibraryItemCard.tsx:208-215 - Artifact list rendering: Uses artifact.kind directly in text without kindLabel() helper (inconsistent with kind badge at line 152).

  7. LibraryItemCard.tsx:267 - Missing export of helper functions: parseMeta, formatDuration, formatBytes, kindLabel, statusColor, jobStateColor are not exported but could be useful for testing or other components.

  8. LibraryItemCard.tsx:253 - ExternalLink icon import unused if no source_url: Actually used conditionally, fine.

  9. Type imports: The diff imports LibraryItem, LibraryArtifact, LibraryJob from @/lib/library but I cannot verify the types exist. The test file imports the same types.

  8. LibraryItemCard.tsx:253 - ExternalLink icon import unused if no source_url: Actually used conditionally, fine.

  9. Type imports: The diff imports LibraryItem, LibraryArtifact, LibraryJob from @/lib/library but I cannot verify the types exist. The test file imports the same types.

Based on the diff provided in your message, here's my code review:


VERDICT: Several correctness bugs, missing error handling, and test gaps


  • LibraryItemCard.tsx:184 - preview variable used but never defined (references preview at line 184 which is only defined in itemMeta at line 120 as const preview = itemMeta.preview ? String(itemMeta.preview) : null;, but the artifact loop at line 184 uses a different preview variable that doesn't exist in that scope)

  • LibraryItemCard.tsx:131 - formatDuration and formatBytes functions are used but not imported (defined in same file but not exported/imported in the component scope - they're defined after the component)

  • LibraryItemCard.tsx:134 - formatDuration(duration) called but formatDuration not imported/defined in component scope (defined at line 49 below component)

  • LibraryItemCard.tsx:135 - formatBytes(item.bytes) called but formatBytes not imported/defined in component scope (defined at line 57 below component)

  • LibraryItemCard.tsx:131-135 - kindLabel, statusColor, jobStateColor functions used but not imported (defined below component at lines 65-77)

  • LibraryItemCard.tsx:151 - parseMeta used but not imported (defined in library.ts but not imported here)

  • LibraryItemCard.tsx:152 - KIND_LABELS, STATUS_COLORS, JOB_STATE_COLORS, TEXT_ARTIFACT_KINDS, ImageIcon, Link, Download, AlertCircle, cn - all used but not imported

  • LibraryItemCard.tsx:174 - thumbnailArtifact.path used directly as src without validation/sanitization - potential XSS if path contains user-controlled data

  • LibraryItemCard.tsx:184 - preview used in artifact loop but preview variable from itemMeta.preview (item-level) is incorrectly used for artifact-level previews (should be artMeta.preview)

  • LibraryItemCard.tsx:195 - onDownload button is permanently disabled with no enable condition - download never works

  • LibraryItemCard.tsx:198 - aria-label="Download (not available yet)" is hardcoded, not dynamic

  • library.ts:13-14 - fetchJson catches all errors and returns fallback silently - swallows network errors, JSON parse errors, and non-JSON responses without logging

  • library.ts:28-30 - listLibraryItems returns fallback { items: [], count: 0 } on any error including 4xx/5xx - callers can't distinguish empty result from failure

  • library.ts:33-42 - getLibraryItem returns null on any error including 404 vs network failure - callers can't distinguish

  • library.ts:45-53 - deleteLibraryItem returns boolean but swallows all errors including 404, 403, network failures

  • library.ts:56-64 - reprocessLibraryItem same issue - returns false for all errors indistinguishably

  • library.ts:75-87 - ingestLibraryUrl returns null for all errors including validation errors (400), auth errors (401), rate limits (429)

  • library.ts:17, 36, 48, 59, 78 - No Content-Type validation on request bodies for POST/DELETE - potential CSRF if cookies used

  • LibraryItemCard.test.tsx - No tests exist (file is empty/new) - zero coverage for a complex component with error states, artifact rendering, job pipeline, actions

  • LibraryItemCard.tsx:120 - parseMeta(item.meta_json) assumes valid JSON - no try/catch for malformed meta_json

  • LibraryItemCard.tsx:171 - onError handler hides image on error but leaves empty space - no fallback UI trigger

  • LibraryItemCard.tsx:176-179 - Error display uses hardcoded text-red-400 instead of design system tokens

  • LibraryItemCard.tsx:195 - Download button permanently disabled with no enable path - feature incomplete without TODO/comment

  • library.ts:13 - fetchJson default fallback parameter allows any type but return type is T - type unsafety if fallback doesn't match T


Style/Consistency:

  • Helper functions (formatDuration, formatBytes, kindLabel, statusColor, jobStateColor) defined after component - violates typical React file organization (helpers first)
  • Multiple unused imports likely (cn, icons, types) - can't verify without imports section
  • Hardcoded color text-red-400 instead of design token
  • Inline styles like w-full aspect-video mixed with utility classes inconsistently
