## Description

Site Diagnostics and Redirects watches two things other plugins treat separately:
your redirects and your crawl health. Everything in this package works out of the
box – there are no locked features, no trial periods, and no required external accounts.

 * Redirect governance: stores redirect rules, then analyzes them for conflicts (
   duplicate sources), loops (A->B->A), chains (3+ hops, with hop count and final
   target), and invalid rules (missing slash, self-redirect, bad status code). One
   click collapses every chain so each source points straight at its final target.
   Conflicted sources are excluded from analysis until you resolve them.
 * Crawl diagnostics: on demand, loopback-crawls your published posts and pages,
   builds a status histogram, and lists broken URLs (4xx/5xx), orphan pages (no 
   internal link points to them), and redirecting URLs.
 * Redirects actually serve on the front end, after chain collapse, so a chain never
   costs your visitors extra hops.
 * Regex redirects: mark any rule as a regular expression and use $1-style backreferences
   in the target, so one rule can move an entire section (e.g. /blog/(\d+) -> /posts/
   $1).
 * Hit telemetry: every rule shows its hit count and last-hit date, so stale rules
   are easy to retire.
 * 404 monitor: every miss is logged with referrer, count, and last-seen, and each
   row has a one-click “redirect it” action.
 * 404 pattern suggestions: groups similar 404s into one regex rule you can apply
   with a click.
 * Permalink guard: rename a published post or page and the plugin automatically
   adds a 301 from the old URL.
 * Scheduled crawl: a weekly or daily WP-Cron crawl compares against the previous
   run and raises a dashboard notice (and optional email to a recipient you choose)
   when NEW broken URLs appear.
 * External link checks: bounded, cached HEAD checks on the outbound links found
   in your latest crawl (up to 20 per run).
 * Import/export: Redirection-compatible CSV plus JSON, both ways, with a diff preview
   before any import is written.

## Installation

    screen.
 2. Activate Site Diagnostics and Redirects.

## FAQ

### Does it crawl external sites?

No. It loopback-crawls your own published content, which is the crawl you are responsible
for. The external link check only HEAD-requests the outbound URLs already found 
on your own pages.

### Is any feature locked behind an account or license?

No. Every feature in this package is fully unlocked.

### What happens to a conflicted redirect?

Both copies are flagged and the pair is excluded from chain/loop analysis until 
you delete one.
