# HW Core — custom WordPress plugin we keep building on

<!-- updated_at: 2026-07-17 16:40:40 -->

## What HW Core is
**Heavyweight Core** is our custom WordPress plugin — not a theme bolt-on. It gives multi-site operators a **Live Dashboard** landing page, **Search Performance** (Google Search Console), **Market Visibility** scans, **API Vault** for client-owned credentials, and **llms.txt** output for AI crawlers.

## Version trail (recent)
| Release | Highlights |
|---------|------------|
| **2.3.0** | Live Dashboard as default admin landing |
| **2.4.0** | GSC + DataForSEO telemetry cards |
| **2.4.2** | Connect-with-Google OAuth (no manual refresh tokens) |
| **2.4.4** | Market Visibility UX + link labels |

## Workflow
We QA on **hw.thatonefirm.com**, package a POSIX zip, then deploy to client networks (House of Cannabis production is the current flagship).

## Philosophy
Clients **own their keys and data**. Vault entries stay in their WordPress install — we configure, they retain.

## Structured data (JSON-LD)

The public **HTML** page at `/lab-notes/hw-core-wordpress-plugin` emits `application/ld+json` with the following `@graph` (Organization, WebSite, WebPage, Article, BreadcrumbList, plus any custom nodes from **SEO JSON-LD extra** in Admin). Assistants should treat the HTML URL as canonical for search; this block is for parity and tooling.

```json
