# Phase 30: Collection View Summary

**Domain-level aggregated dashboard: metric cards (papers/fulltext-ready/deep-read), lifecycle bar chart, and health overview grid with healthy/unhealthy counts for PDF/OCR/Note/Asset dimensions**

## Performance

- **Duration:** 2 min
- **Started:** 2026-05-04T21:58:32Z
- **Completed:** 2026-05-04T22:01:09Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments
- Replaced `_renderCollectionMode()` placeholder (30 lines) with full collection view rendering (83 lines) including single-pass aggregation, metric cards row, lifecycle bar chart, and health overview
- Added `_renderCollectionHealth(container, healthAgg)` helper with 4-dimension grid (PDF Health, OCR Health, Note Health, Asset Health) showing healthy/unhealthy counts with color-coded labels
- Added CSS Section 17 with collection view layout classes: `.paperforge-collection-view` (flex column), `.paperforge-collection-metrics` (auto-fit grid), `.paperforge-collection-health` (2-column grid), health cell/counts with ok/warn/fail coloring
- Empty domain handled via `_renderEmptyState()` instead of placeholder text
- All existing Phase 27 and Phase 28 methods left untouched — pure wiring phase

## Task Commits

Each task was committed atomically:

1. **Task 1: Add Section 17 CSS for collection view layout** - `18accff` (style)
2. **Task 2: Replace _renderCollectionMode placeholder with full collection view** - `a54fb47` (feat)

## Files Created/Modified
- `paperforge/plugin/styles.css` - Added Section 17 (Collection View Layout) with `.paperforge-collection-view`, `.paperforge-collection-metrics`, `.paperforge-collection-health`, `.paperforge-collection-health-cell`, `.paperforge-collection-health-counts` classes with ok/warn/fail color variants
- `paperforge/plugin/main.js` - Replaced `_renderCollectionMode()` placeholder (11-line placeholder + contentEl.createEl) with full implementation (83 lines) including single-pass aggregation, metric cards with progress bars, lifecycle bar chart via `_renderBarChart()`, and `_renderCollectionHealth(container, healthAgg)` with 4-dimension health grid

## Decisions Made
- **Fulltext-ready threshold**: Items with lifecycle in `['fulltext_ready', 'deep_read', 'ai_ready']` count toward the fulltext-ready metric with a progress bar against total papers
- **Deep-read threshold**: Items with lifecycle in `['deep_read', 'ai_ready']` count toward the deep-read metric with a progress bar against total papers
- **Health dimension labels**: PDF (Healthy/Broken), OCR (Done/Pending-Failed), Note (Present/Missing), Asset (Valid/Drifted) — concise labels reflecting the binary split of each dimension
- **Health source**: Aggregated inline from domain-filtered items (iterating `item.health` per entry), not from `_cachedStats` global aggregate — ensures domain-specific accuracy
- **Zero papers**: Renders `_renderEmptyState()` with human-readable message, not a generic placeholder

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None.

## Next Phase Readiness
- Collection view fully wired: Phase 28 `_switchMode('collection')` -> `_renderCollectionMode()` now renders complete collection dashboard with metric cards, lifecycle bar chart, and aggregated health overview
- Phase 30 is the last phase in v1.7 Context-Aware Dashboard milestone — milestone is now complete
- No blockers
