## Description

After you replace or update a PDF in the Media Library, clients and agencies often
need a quick answer: which pages still point at this file, and does the public URL
match the file on disk?

**Aschere PDF Reference Verifier** (free) is a read-only Tools screen that:

 1. Lets an administrator pick **one** local PDF from the Media Library
 2. Scans **core post and page** body content (including the core File block) for direct
    file URLs
 3. Lists referencing pages and their public/publish status
 4. Shows local size, mtime, and SHA-256
 5. Optionally fetches the attachment URL **once** from this site only (SSRF-safe host
    check) and compares the hash
 6. Builds a plain-text **delivery snapshot** you can copy or download

This plugin does **not** replace files, edit content, or change download permissions.

#### Coverage honesty

Uncovered sources (Elementor, Bricks, ACF fields, offload/CDN rewrites, menus, widgets,
etc.) are labeled **not covered**. Zero hits inside coverage is **never** shown 
as a site-wide “no references” conclusion.

#### What this free version does not do

 * Batch or scheduled scans
 * Automatic replace / rollback
 * Full-site cache purge promises
 * Legal/compliance audit certificates
 * Checkout, tax, security gateway, SEO, forms, or page-builder deep integration

## Installation

 1. Upload the `aschere-pdf-reference-verifier` folder to `/wp-content/plugins/`
 2. Activate the plugin through the Plugins screen
 3. Open **Tools  Aschere PDF Reference Verifier**

## FAQ

### Does this replace file-replacement plugins?

No. File-replacement plugins swap the file. This plugin verifies references and 
identity after a change (or before delivery).

### Can it scan ACF / Elementor?

Not in the free version. Those locations are explicitly marked not covered.

### Is the public fetch safe?

Fetches are limited to the same host as `home_url()`, HTTP(S) only, short timeout.
Failures are reported as `unknown`.
