Phase Implementation Verification

Phase 1: Database Schema Verification & Updates

Status: ✅ ASSUMED COMPLETE (completed before this session) Evidence:

• Recommendation.txt line 290 states "Go with phase 2" - indicating Phase 1 was done
• migration_work_order_persistence.sql referenced in recommendation
• Phases 2-6 reference cycle_count and good_parts columns as existing

Requirements:

• work_orders table has cycle_count column (INT DEFAULT 0)
• work_orders table has good_parts column (INT DEFAULT 0)
• work_orders table has progress_percent column
• Indexes on work_order_id and status
• Migration SQL created

---

Phase 2: Add Cycle Persistence to work_orders Table

Status: ✅ COMPLETE Implementation Date: 2025-11-29

Requirements:

• Modified Machine Cycles function to add throttled DB updates
• Added 5-second throttling logic using global.lastWorkOrderDbWrite
• Calculate good_parts = (cycles × cavities) - scrap
• Output on port 4 sends SQL UPDATE
• Wired to DB Guard → mariaDB

SQL Implemented:

UPDATE work_orders
SET cycle_count = ?,
    good_parts = ?,
    progress_percent = ?,
    updated_at = NOW()
WHERE work_order_id = ?

Files Modified:

• flows.json - Machine Cycles function (ID: 0d023d87a13bf56f)

Verification:

cat flows.json | jq '.[] | select(.name == "Machine cycles") | .func' | grep "lastWorkOrderDbWrite"

Expected: Should find throttling logic

Phase 3: Implement Resume/Restart Prompt on Load

Status: ✅ BACKEND COMPLETE, ⏳ UI DIALOG PENDING Implementation Date: 2025-11-29

Requirements:

• Modified start-work-order to query DB for existing progress
• Added resume-work-order action handler
• Added restart-work-order action handler
• Backend sends resumePrompt message to UI
• Modified Refresh Trigger to route check-progress mode
• Modified Back to UI to process check-progress results
• UI template dialog for Resume/Restart (NOT IMPLEMENTED - UI work needed)

Actions Added to Work Order buttons:

1. start-work-order: Queries SELECT cycle_count, good_parts, progress_percent FROM work_orders WHERE work_order_id = ?
2. resume-work-order: Loads existing values from database into global state
3. restart-work-order: Resets database and global state to 0

New Modes in Back to UI:

1. check-progress: Sends resumePrompt if progress exists
2. resume: Sends activeWorkOrder with database values
3. restart: Sends activeWorkOrder with zeroed values

Files Modified:

• flows.json - Work Order buttons function
• flows.json - Refresh Trigger function
• flows.json - Back to UI function

Backup: flows.json.backup_phase3_20251129_060803

Remaining Work:

• Add Home template dialog listening for msg.topic === "resumePrompt"
• See CHANGES_REFERENCE.md for example implementation

---

Phase 4: Fix Complete Button to Persist Final Counts

Status: ✅ COMPLETE Implementation Date: 2025-11-29

Requirements:

• Modified complete-work-order to write final counts before marking DONE
• SQL includes cycle_count, good_parts, progress_percent = 100
• Retrieves values from global state before clearing

SQL Implemented:

UPDATE work_orders
SET status = 'DONE',
    cycle_count = ?,
    good_parts = ?,
    progress_percent = 100,
    updated_at = NOW()
WHERE work_order_id = ?

Code Added:

const finalCycles = Number(global.get("cycleCount")) || 0;
const cavities = Number(global.get("moldActive")) || 1;
const scrapTotal = Number(activeOrder.scrap) || 0;
const totalProduced = finalCycles * cavities;
const finalGoodParts = Math.max(0, totalProduced - scrapTotal);

Files Modified:

• flows.json - Work Order buttons function (complete-work-order case)

Backup: flows.json.backup_phase4_20251129_061140

Verification:

cat flows.json | jq '.[] | select(.name == "Work Order buttons") | .func' | grep -A 5 "complete-work-order"

Expected: Should show finalCycles and finalGoodParts calculation

---

Phase 5: Update Session Restore to Set RUNNING Status

Status: ✅ COMPLETE Implementation Date: 2025-11-29

Requirements:

• Work order remains RUNNING after restore
• User must click START to begin tracking (trackingEnabled = false)
• Global state restored from database (cycleCount, activeWorkOrder)
• No auto-start on restore

User Feedback Addressed: ✅ "Make sure user still has to click start for it to start counting" ✅ "should be running so doesn't have to load again" ✅ "but user must confirm with start button"

Implementation: Already correct in restore-query mode:

• Query: SELECT * FROM work_orders WHERE status = 'RUNNING' LIMIT 1
• Sets: trackingEnabled = false, productionStarted = false
• Work order status stays RUNNING in database
• User clicks START to begin tracking

Files Modified:

• flows.json - Back to UI function (restore-query mode - documentation enhanced)

No Database UPDATE Needed: Work order is already RUNNING when queried

---

Phase 6: Load Work Order Data from Database (Not Session)

Status: ✅ COMPLETE Implementation Date: 2025-11-29

Requirements:

• Work orders load from database, not assuming zeros
• Resume uses database values to initialize global state
• Restart resets both database AND global state
• UI displays database values
• Database is source of truth

User Feedback Addressed: ✅ "Be extra careful with this step, you are modifying existing logic" ✅ "Make sure to check for potential side-effects"

Implementation Details:

1. start-work-order queries DB before loading (Phase 3)
2. resume-work-order: global.set("cycleCount", existingCycles) from DB
3. restart-work-order: Database UPDATE to reset values + global state reset
4. restore-query: Loads cycleCount from row.cycle_count
5. All UI messages use database values from queries

Data Flow:

User Action → Query DB → Initialize Global State from DB → Update UI

Files Modified:

• All Phase 3 modifications already implement Phase 6 requirements
• Database values are loaded first, then used to set global state

Side Effects Checked:

• ✅ No conflicts with existing cycle tracking
• ✅ Throttled persistence still works (Phase 2)
• ✅ Complete button uses global state (refreshed from DB on load)
• ✅ Resume/Restart don't interfere with session_state persistence

---

Phase 7: Add Tab Switch State Refresh

Status: ⏳ TO BE IMPLEMENTED Goal: Ensure UI shows latest data when returning to Home tab

Requirements:

• Add tab activation listener in Home template
• On tab activation, query work_orders for active RUNNING order
• Update UI with fresh database data
• Don't interfere with real-time cycle updates

Implementation Strategy:

1. Add ui-control listener for tab change events
2. When Home tab is activated, send get-current-state action
3. Optionally query database for latest work_order data
4. Update UI displays

Files to Modify:

• flows.json - Home Template node

Dependencies: ✅ Phase 6 complete (database as source of truth)

Risk Level: LOW (purely UI enhancement)

---

Phase 8: Testing & Validation

Status: ⏳ TO BE COMPLETED AFTER PHASE 7 Goal: Verify all scenarios work correctly

Test Cases: See Recommendation.txt lines 209-241

Documentation Created:

• ✅ IMPLEMENTATION_SUMMARY.md - Complete testing checklist
• ⏳ Will be updated after Phase 7 implementation
