# Phase 39: Base View Fix — Summary

**Status:** Complete ✅
**Requirements:** BASE-01 through BASE-05 — all verified

## One-Liner
Removed ghost lifecycle/maturity/next_step from Base views, restored workflow flags (has_pdf/do_ocr/analyze/ocr_status), changed folder filter to Literature/, regenerated .base files with master-version workflow-gate filters.

## Key Deliverables
- `PROPERTIES_YAML`: replaced lifecycle/maturity_level/next_step with has_pdf/do_ocr/analyze/ocr_status
- `build_base_views()`: 8 views use workflow-gate filters (do_ocr=true, analyze=true + ocr_status=done, etc.) matching master version
- `ensure_base_views()`: folder filter changed from `${LIBRARY_RECORDS}` to `${LITERATURE}`
- `substitute_config_placeholders()`: added `LITERATURE` substitution key
- `_update_folder_filter()` automatically migrates existing Base files on next sync

## Verification
- 26 tests pass (base_views + base_preservation)
- No lifecycle/maturity columns in generated Base YAML
- Workflow flags present in all 8 views
