- Full inventory UI: product list with search/filter, product detail with
tabs (details, units, suppliers, stock receipts, price history)
- Product filters: category, type (serialized/rental/repair), low stock,
active/inactive — all server-side with URL-synced state
- Product-supplier junction: link products to multiple suppliers with
preferred flag, joined supplier details in UI
- Stock receipts: record incoming stock with supplier, qty, cost per unit,
invoice number; auto-increments qty_on_hand for non-serialized products
- Price history tab on product detail page
- categories/all endpoint to avoid pagination limit on dropdown fetches
- categoryId filter on product list endpoint
- Repair parts and additional inventory items in music store seed data
- isDualUseRepair corrected: instruments set to false, strings/parts true
- Product-supplier links and stock receipts in seed data
- Price history seed data simulating cost increases over past year
- 37 API tests covering categories, suppliers, products, units,
product-suppliers, and stock receipts
- alert-dialog and checkbox UI components
- sync-and-deploy.sh script for rsync + remote deploy
- New tables: lesson_plan_template, lesson_plan_template_section, lesson_plan_template_item
- skill_level enum: beginner, intermediate, advanced, all_levels
- Templates are reusable curriculum definitions independent of any member/enrollment
- POST /lesson-plan-templates/:id/create-plan deep-copies the template into a member plan
- Instantiation uses template name as default plan title, accepts custom title override
- Instantiation deactivates any existing active plan on the enrollment (one-active rule)
- Plan items are independent copies — renaming the template does not affect existing plans
- 11 new integration tests
- New tables: lesson_plan_item_grade_history (append-only), lesson_session_plan_item
- Grading an item updates current_grade_value and creates immutable history record
- Grading a not_started item auto-transitions it to in_progress
- Linking items to a session also auto-transitions not_started items
- Link operation is idempotent — re-linking same items produces no duplicates
- Endpoints: POST/GET /lesson-plan-items/:id/grades, GET /lesson-plan-items/:id/grade-history
- Endpoints: POST/GET /lesson-sessions/:id/plan-items
- 8 new integration tests
