refactor(core): rename top-level directories for clarity

[GiZano]

Overview

This PR renames the three top-level project directories to shorter, more precise names. The previous names (backend-data-elaborator, frontend-mobile-app, iot-data-harvester) were overly verbose, making terminal commands, CI path filters, and documentation references unnecessarily long. The new names better reflect what each directory actually contains.

Old | New -- | -- backend-data-elaborator/ | backend/ frontend-mobile-app/ | mobile/ iot-data-harvester/ | firmware/

Changes Made

Directory renames

• backend-data-elaborator/ → backend/
• frontend-mobile-app/ → mobile/
• iot-data-harvester/ → firmware/

.github/workflows/backend-ci.yml

yaml

# Before
paths:
  - 'backend-data-elaborator/**'
  - '.github/workflows/backend-ci.yml'

# After
paths:
  - 'backend/**'
  - '.github/workflows/backend-ci.yml'

Also update the cd commands and hashFiles path inside the job steps:

yaml

key: ${{ runner.os }}-pip-${{ hashFiles('backend/api/requirements.txt') }}
# ...
cd backend/api

.github/workflows/frontend-ci.yml

yaml

# Before
paths:
  - 'frontend-mobile-app/**'

# After
paths:
  - 'mobile/**'

yaml

key: ${{ runner.os }}-node-${{ hashFiles('mobile/package-lock.json') }}
# ...
cd mobile

.github/workflows/iot-ci.yml

yaml

# Before
paths:
  - 'iot-data-harvester/**'

# After
paths:
  - 'firmware/**'

yaml

cd firmware/esp32_code

README.md — Update project structure section:

QuakeGuard/
├── backend/
│   └── api/
├── mobile/
│   ├── app/
│   ├── src/
│   └── context/
└── firmware/
    └── esp32_code/
        └── src/

docker-compose.yml — Verify build context paths if any reference the old directory name directly.

stress_test.py — Verify no hardcoded relative paths reference the old directory name.

Impact

No functional changes. Pure structural refactor. All CI pipelines, Docker builds, and application code behavior remain identical.

⚠️ Action Required for all developers

After pulling this branch, your local repository structure will change. Run:

bash

git pull origin develop

If you have any local scripts or aliases pointing to the old directory names, update them manually.

Testing Performed

• Verified backend-ci.yml triggers correctly on a change inside backend/
• Verified frontend-ci.yml triggers correctly on a change inside mobile/
• Verified iot-ci.yml triggers correctly on a change inside firmware/
• Verified docker compose up --build completes successfully from the new path
• Verified stress test runs correctly from backend/api/
