## Description

ListingCore Diagnostics inspects a WordPress installation and reports what it can
directly observe — versions, update state, security and performance configuration,
database metadata, error-log activity, and more — without guessing.

**Project Philosophy:**

> ListingCore Diagnostics should report what it can prove, not what it merely suspects.

**Current capabilities:**

 * 32 static, read-only, deterministic diagnostics across core, configuration, security,
   performance, database, plugins, and themes.
 * A factual diagnostic summary (total, severity, and category counts) with no scoring
   or interpretation.
 * Aggregate evidence only — no raw option dumps, credentials, or paths.
 * One reversible fix (`fix.site_urls_align`) with preview, confirmation, verification,
   and rollback.
 * A capability-gated admin page with fully escaped output.

ListingCore Diagnostics deliberately avoids speculative diagnosis, plugin blame,
root-cause claims, health scoring, AI/ML, arbitrary filesystem scanning, arbitrary
SQL, external HTTP, and telemetry. Diagnostics are read-only; the only mutation 
path is a single, explicitly confirmed, nonce-protected fix.

### Requirements

 * WordPress 6.0 or higher
 * PHP 7.4 or higher
 * MySQL 5.7 or higher (or MariaDB 10.2+)

### Security

 * Diagnostics are read-only and aggregate-only
 * The single fix requires the `manage_options` capability and a valid nonce
 * All output is escaped
 * No external HTTP, telemetry, or automatic data modification

See docs/SECURITY.md for details.

## Changelog

#### 1.2.0

 * Rollback outcome correctness: an unchanged write is no longer misreported as 
   a rollback failure.
 * Value-bound fix confirmation: approval is now bound to the exact previewed before-
   state and direction.
 * Shared LogFileReader across the debug-log diagnostics, so the bounded log tail
   is read once per scan.
 * Coalesced database metadata queries via a shared read-only DatabaseMetadata provider.
 * Four new read-only diagnostics: core.wp_cron, database.upgrade_pending, configuration.
   upload_limits, security.xmlrpc (32 total).
 * Unified site URL comparison semantics shared by configuration.site_urls and fix.
   site_urls_align.
 * Environment-aware suppression for approved environment-sensitive diagnostics;
   unknown environments never suppress and security-posture/ERROR results are never
   suppressed.
 * Admin UX: “All Diagnostics” is a collapsed native disclosure and the fix confirmation
   shows trusted Before -> After values.
 * Tooling: committed PHPUnit configuration, GitHub Actions CI, and reproducible
   forward-slash packaging scripts.
 * Added the ListingCore Diagnostics translation template (POT) for translations.
