benjamin.baker 01734e5449 harden CSV import reconciliation and preserve saved model selections
Default fuzzy reconcile threshold to 0 and refuse merges when digit runs differ so numbered labels like Bay 311 never bind to Bay 310. Keep edit forms from clearing saved model fields when category filtering hides untyped rows. Includes in-progress computers policy and endpoints command feature work.

# Copilot instructions for shopdb-flask
Follow these when suggesting code. They are enforced by a naming/style hook and
by CI (`.github/workflows/ci.yml`) - suggestions that break them fail the build.
`CONTRIBUTING.md` is the full authority; this is the short version.
## Naming (LOCKED - the hook rejects violations)
- **DB tables**: lowercase, concatenated, plural. No underscores, no dashes.
`machines`, `networkdevices`, `businessunits` - NOT `machine_types`, `BusinessUnits`.
- **DB columns**: lowercase, concatenated, singular. No underscores.
`machineid`, `lastzabbixsync`, `isactive` - NOT `machine_id`, `last_zabbix_sync`.
- **Foreign keys**: referenced table (singular) + `id`: `locationid`, `vendorid`.
- **Booleans**: `is`/`has` prefix: `isactive`, `isshopfloor`.
- **Index names**: `idx_<table>_<column>` (underscores allowed here only).
### Python
- A variable, attribute, function, or dict key that holds a DB value MUST match
the column name exactly - do NOT convert to snake_case.
Column `machineid` -> `Machine.machineid`, `{"machineid": 1}`, local `machineid`.
- Pure code that does NOT mirror a DB field uses normal snake_case (PEP 8):
`loop_count`, `current_user`, `validate_input()`.
- Classes: PascalCase, spelled out (`NetworkDevice`, `AssetType`).
### JavaScript / Vue
- A JS variable holding an API field value matches the API key exactly - do NOT
camelCase it. API `{"machineid": 1}` -> `response.machineid`, never `machineId`.
- Components: PascalCase (`AssetDetail.vue`). CSS classes: lowercase-with-dashes.
### API
- Endpoints: lowercase plural nouns, no underscores/dashes: `/api/networkdevices`.
- Query params + response keys match column names: `?locationid=5`,
`{"machineid": 1, "lastzabbixsync": "..."}`.
### Allowed acronyms only
Universal: id url api http https json jwt sql os ip dns csv pdf cors ttl uuid
html css orm. Domain: cmm cnc pc usb vnc winrm ssh ssl tls tcp udp smtp ldap
vlan sso dnc focas clm mtconnect. Anything else: spell it out.
### Banned shorthand
Never use `cfg ctx mgr req res env util helper` or `db` as a standalone variable
name. Spell out: `config context manager request response environment utilities`.
`_bp` is fine only as a suffix with a meaningful prefix (`printers_bp`).
## Style (ASCII only)
- NO emojis anywhere - code, comments, strings, UI.
- NO em-dashes, en-dashes, Unicode arrows, or smart quotes. Plain ASCII only.
- Comments default to NONE. Add one only when the WHY is non-obvious; keep inline
`#`/`//` comments terse. Docstrings stay normal English.
- Dark theme is the default; keep UI functional and professional.
## Architecture (do not violate)
- **Plugins are the product.** Plugin code lives in `plugins/<name>/{models,api,services,schemas}/`
with a `manifest.json` (single source of truth: name, version, dependencies,
api_prefix) and a `BasePlugin` subclass in `plugin.py`.
- **Plugins never import core internals.** Use the contract surface `shopdb.api`
(e.g. `from shopdb.api import db, Asset, success_response`). Adding to that
surface is a contract-version bump + a `docs/PLUGIN-HOOKS` update in the same PR.
- **Migrations, never `db.create_all()`.** The core Alembic chain is in
`migrations/versions/`; each plugin owns its own chain under
`plugins/<name>/migrations/`. New schema = a new migration with an idempotent
guard and a real downgrade. Migrations must run clean on strict MySQL 8.
- **Asset model is the platform contract.** Physical things are an `Asset` plus a
plugin subtype row linked by `assetid` (FK, `ON DELETE CASCADE`). Consumables
with quantities are standalone tables, not assets.
- **Ledger pattern**: a cached `quantityonhand` moves in the SAME commit as the
signed transaction row it reflects.
- **Configuration for endpoint agent**: The endpoint agent's live collector key and base URL are provisioned in the Windows registry `HKLM\SOFTWARE\GE\ShopDB` (values `CollectorKey`, `BaseUrl`), not committed in `appsettings.json`; `appsettings.json` holds only non-secret runtime settings.
## Before you finish a change
Run the three gates (CI runs the same):
```
python -m pytest tests/ -q
cd frontend && npx vitest run && npm run build && cd ..
bash scripts/check-naming-and-style.sh
```
Commits: short present-tense subject, body says WHY. No AI/tool attribution in
commit messages, code comments, or docs.
