cproudlock d6725c08e0 Phase 0: lock platform contract, naming convention, and style enforcement 
Establishes the framework's foundation as a multi-site adoptable platform.

ADRs (migrations/adr/):
- ADR-001 (ACCEPTED): Asset is the platform contract; Machine retires.
  Three relationship types (partof, controls, connectedto) with free-text
  label, position-resolution chain (asset > related > location),
  hierarchical locations, sibling-bay propagation.
- ADR-002 (ACCEPTED): Plugin contract semver via __contract_version__.
- ADR-003 (ACCEPTED): Hybrid plugin distribution (in-tree bundled +
  filesystem-based external).
- ADR-004 (ACCEPTED): Per-site instances, not multi-tenant.
- ADR-005 (ACCEPTED): Equipment plugin (manufacturing) split from
  measuringtools plugin (metrology). Subtype-table pattern for protocol
  data (FOCAS, CLM, MTConnect).
- ADR-006 (ACCEPTED): Plugin collector contract via get_collector_schema
  hook with API-key auth and identity-based upsert.

Naming convention v1 (CONTRIBUTING.md):
- DB tables/columns: lowercase concatenated, no underscores or dashes
- DB-mirrored Python/JS variables match column names exactly; pure code
  follows host-language convention (PEP 8 / camelCase)
- Closed acronym allowlist (universal + shop-floor domain), banned
  shorthand list with suffix exception (printers_bp etc allowed)
- Plain ASCII everywhere: chat, docs, comments, string literals

Style enforcement (scripts/check-naming-and-style.sh):
- Pre-commit-runnable check script: non-ASCII, banned shorthand,
  snake_case DB names, snake_case API params in frontend
- Fixes 14 violations across 11 files (Unicode arrows, snake_case
  params, ctx -> canvasContext, res -> response, req -> request_obj)

Project state (CLAUDE.md, README.md, frontend/CLAUDE.md):
- De-staled CLAUDE.md to reflect actual current state
- README unifies DB story (MySQL canonical, SQLite test-only)
- frontend/CLAUDE.md points at root convention

# ShopDB Flask Project
Modern rewrite of the classic-ASP shopdb. Built as a framework so sister GE Aerospace sites can adopt it. Plugin system is the product.
## Database
- **Active database:** `shopdb_flask` (MySQL, asset-based schema)
- **Legacy database:** `shopdb` (Classic ASP schema, used only for one-time data import via `scripts/import_from_mysql.py`)
- **Connection:** `.env` file. See `.env.example`.
Architecture decisions live in `migrations/adr/`. Read those before making schema or contract changes.
- ADR-001: Asset model is the platform contract (Machine retires) - ACCEPTED
- ADR-002: Plugin contract versioning (semver) - ACCEPTED
- ADR-003: Plugin distribution model (in-tree bundled + filesystem-based external) - ACCEPTED
- ADR-004: Deployment topology (per-site instances, not multi-tenant) - ACCEPTED
- ADR-005: Equipment vs measuringtools plugin scope - ACCEPTED
- ADR-006: Plugin collector contract pattern - ACCEPTED
## Coding convention
`CONTRIBUTING.md` defines naming rules (DB tables, columns, Python, JS, Vue, API). Pre-commit hook at `scripts/check-naming-and-style.sh` enforces them. Read `CONTRIBUTING.md` before naming any new identifier.
## Current state (as of 2026-05-08)
### Wired in
- App factory pattern, Flask 3 + SQLAlchemy + Flask-Migrate + JWT + Marshmallow + CORS + Caching
- 6 plugins: computers, equipment, network, notifications, printers, usb
- Plugin contract: `BasePlugin` ABC, `PluginMeta`, registry, dependency-aware loader
- JWT auth with refresh tokens, audit logging, system settings, user management
- Frontend: Vue 3 + Pinia + Vite, dynamic plugin routing, dark mode default
- Search across all plugins via `get_searchable_fields` hook
- Asset relationships (cross-plugin)
### In progress / partial
- **Dual model coexistence**: legacy `Machine` and new `Asset` both live. ADR-001 settles direction (Asset wins). Migration plan is the next concrete deliverable.
- **Plugin verification**: 6 plugins follow `BasePlugin` interface but no contract test asserts compliance. Skill `enforcing-plugin-contract` and the contract test suite are pending.
- **Tests**: hollow. `tests/conftest.py` exists but uses Flask-SQLAlchemy 2.x patterns that error on 3.x. No actual test files. Skill `pinning-flask-behavior` covers the rebuild.
### Pending
- Alembic versions directory exists (`migrations/versions/`) but is empty. No migrations have been generated yet. Run `flask db init` is partial; need `flask db migrate` to capture current schema.
- Plugin scaffold CLI (`flask plugin new <name>`)
- Plugin author docs (`docs/PLUGIN-QUICKSTART.md`, `docs/PLUGIN-REFERENCE.md`)
- Per-site deploy story (`Dockerfile`, `docs/DEPLOY.md`)
- Frontend hook contract (asset-detail, map markers, search results)
## Quick start
```bash
# Start dev environment
~/start-dev-env.sh
# Activate venv and install deps
cd /home/camp/projects/shopdb-flask
source venv/bin/activate
pip install -r requirements.txt
# Configure environment
cp .env.example .env
# Edit .env with DB credentials, JWT secrets
# Create / update database tables
flask db-utils create-all
# Seed reference data
flask seed reference-data
# Restart services
pm2 restart shopdb-flask-api shopdb-flask-ui
```
## Service URLs
- Flask API: http://localhost:5001
- Flask UI: http://localhost:5173
- Legacy ASP (data source for one-time import): http://192.168.122.151:8080
## Plugin structure
```
plugins/
<plugin_name>/
__init__.py
plugin.py # BasePlugin implementation
manifest.json # Plugin metadata (name, version, dependencies, api_prefix)
models/
__init__.py # Export all models
<model>.py # SQLAlchemy models
api/
__init__.py
routes.py # Flask Blueprint
services/ # Optional, business logic
schemas/ # Optional, marshmallow schemas
migrations/ # Optional, plugin-specific Alembic migrations
```
Each plugin must have:
- `models/__init__.py` exports all models
- `plugin.py` extends `BasePlugin`
- `manifest.json` with metadata (single source of truth per ADR-002)
- No direct imports from core code (use the contract surface defined in ADR-001)
## Key files
- `shopdb/__init__.py` - app factory, blueprint registration
- `shopdb/plugins/base.py` - BasePlugin ABC, PluginMeta dataclass
- `shopdb/plugins/loader.py` - filesystem discovery, dependency-aware loading
- `shopdb/core/api/assets.py` - example of optional plugin imports
- `frontend/src/router/index.js` - frontend routing
- `frontend/src/components/AppSidebar.vue` - navigation menu
- `migrations/adr/` - architecture decision records
## Migration notes
- `migrations/DATA_MIGRATION_GUIDE.md` - one-time import from legacy ASP shopdb
- `migrations/MIGRATE_USB_DEVICES_FROM_EQUIPMENT.md` - USB device migration from equipment table
- `migrations/FIX_LOCATIONONLY_EQUIPMENT_TYPES.md` - LocationOnly equipment type fix
- `migrations/PRODUCTION_MIGRATION_GUIDE.md` - production import methods
- `migrations/rename_underscore_columns.sql` - one-time rename of snake_case columns to lowercase concatenated (per CONTRIBUTING.md)
- `migrations/versions/` - Alembic versions (currently empty)
