Nameru Thaparequested to merge
improvement/prototype-hardening into main

Summary

  • Added server-side validation for production-job creation
  • Added validation for production steps, job activation, station inventory, and transfer fulfillment
  • Prevented negative inventory values
  • Prevented jobs without production steps from being activated
  • Prevented changes to production configuration after activation
  • Prevented zero, invalid, excessive, or repeated transfer fulfillment
  • Added shared responsive styling across all five application pages
  • Added smoke tests for main pages, job details, and static CSS delivery
  • Preserved the existing TC-01 through TC-15 workflow

Input Validation

Production jobs

  • Job name is required
  • Production quantity must be at least 1
  • Low-stock threshold must be between 0% and 100%
  • Invalid numeric input returns a controlled validation response
  • Invalid input does not create a database record

Production steps

  • Only Draft jobs can be modified
  • A valid station is required
  • Production instruction is required
  • Required part name is required
  • Required part quantity must be at least 1

Job activation

  • Only Draft jobs can be activated
  • At least one production step is required before activation
  • Invalid activation does not create a barcode or product units

Station inventory

  • Station and part references must be valid
  • Quantity must be numeric
  • Negative station inventory is rejected

Transfer fulfillment

  • Transferred quantity must be numeric and greater than zero
  • Transferred quantity cannot exceed the remaining requested quantity
  • Fulfilled requests cannot be fulfilled again
  • Rejected transfers do not modify station inventory

Interface Improvements

  • Added one shared responsive stylesheet
  • Standardized page background, navigation, forms, buttons, tables, alerts, and status messages
  • Added mobile-friendly table behavior
  • Applied consistent styling to:
    • Production Jobs
    • Job Details
    • Station Inventory
    • Warehouse Requests
    • Worker Kiosk

Test Coverage

Automated command:

python -m pytest -q

Result:

32 passed

Coverage includes:

  • 15 functional test cases covering TC-01 through TC-15
  • 10 validation test results
  • 7 application smoke-test results

Smoke coverage verifies:

  • Production Jobs page
  • Station Inventory page
  • Warehouse Requests page
  • Worker Kiosk page
  • Job Details page
  • Static stylesheet availability
  • Correct CSS response type

Technical Verification

  • python -m pip check — no broken requirements
  • Python application modules compile successfully
  • All expected Flask routes are registered
  • All 32 tests pass
  • All five main pages load with the shared styling
  • Working tree is clean

Increment Scope

README and final-project documentation are intentionally deferred until the complete final prototype is ready.
