<p>The Escape Button is a simple floating action button that allows users to quickly and safely exit your website in case of emergency. We originally developed this tool to support survivors of sexual and domestic violence and hope it can be useful for the community as well.</p>
<p>The Escape Button is built to handle both situations where the user or browser does not have Javascript enabled and when it does.</p>
<p>It is possible to override the styling of the Escape Button in your own stylesheet.</p>

Escape Button

We developed the Our Wave Escape Button (available in the bottom right of our website) to help protect our users in unsafe situations.

<p>Tessera is a developer library for plugin authors who register abilities via <code>wp_register_ability()</code> and want snapshot capture, audit logging, approval workflows, and one-click rollback for every invocation across REST, MCP, internal PHP, and WP-CLI without building it themselves.</p>
<p>Declare what state your ability touches; Tessera handles the safety wrapper.</p>
<h4>What you get out of the box</h4>
<ul>
<li><strong>Pre + post snapshots.</strong> Every safety-enabled invocation captures declared state before the callback and (on success) after, so the audit log can show a real diff.</li>
<li><strong>Audit log.</strong> One row per invocation with ability name, caller (REST/MCP/CLI/internal), user, args, result, status, duration, pre/post hashes, and parent_invocation_id for nested calls.</li>
<li><strong>One-click rollback.</strong> Restore captured state from post_meta, options, taxonomy term assignments, user roles + caps. File contents support tiered drift detection (mtime / mtime_size / critical_hash / full_hash) plus opt-in real byte-level rollback via <code>full_content</code> strategy.</li>
<li><strong>Drift check on rollback.</strong> Live state is hashed and compared to the snapshot’s post-state before restoring; if they differ the rollback returns an error unless forced.</li>
<li><strong>Concurrency lock.</strong> Capture + execute is serialised per surface set via a MySQL advisory lock so two simultaneous invocations do not capture each other’s mid-states.</li>
<li><strong>Encrypted redaction.</strong> Scrub secrets out of args, results, and snapshots. Stores redacted values as AES-256-GCM envelopes so rollback can still restore them.</li>
<li><strong>Approval queue.</strong> When <code>safety.requires_approval</code> is set, the wrapper blocks execution and returns a 202 pending response. A human approves or rejects via wp-admin, WP-CLI, or REST. Multi-stage sequential or parallel approval chains are supported.</li>
<li><strong>Multisite support.</strong> Each subsite gets its own set of <code>wp_<N>_abilityguard_*</code> tables, with auto-install on <code>wp_initialize_site</code> and auto-drop on <code>wpmu_drop_tables</code>.</li>
<li><strong>Retention.</strong> Daily WP-Cron prunes old log rows (defaults: 30 days normal, 180 days destructive) and orphaned snapshots.</li>
</ul>
<h4>Surfaces</h4>
<ul>
<li><strong>PHP API</strong> with <code>wp_register_ability( $name, [ ..., 'safety' => [...] ] )</code> and helpers <code>abilityguard_rollback</code>, <code>abilityguard_snapshot_meta</code>, <code>abilityguard_snapshot_options</code>.</li>
<li><strong>REST</strong>: <code>/abilityguard/v1/log</code>, <code>/log/<id></code>, <code>/log/export</code>, <code>/rollback/<id></code>, <code>/rollback/bulk</code>, <code>/approval</code>, <code>/approval/<id>/approve</code>, <code>/approval/<id>/reject</code>, <code>/approval/bulk</code>, <code>/approval/export</code>, <code>/retention</code>, <code>/retention/prune</code>, <code>/health</code>.</li>
<li><strong>WP-CLI</strong>: <code>wp abilityguard log list/show</code>, <code>wp abilityguard rollback <id></code>, <code>wp abilityguard approval list/approve/reject <id></code>, <code>wp abilityguard prune</code>.</li>
<li><strong>wp-admin</strong>: Tools > Tessera. Hybrid timeline + command-palette search, snapshot drawer, JSON-highlighted Input/Result tabs, invocation chain navigation, and real rollback against the captured snapshot.</li>
</ul>
<h4>Example</h4>
<pre><code>wp_register_ability( 'my-plugin/update-product-price', array(
    'label'               => 'Update product price',
    'description'         => 'Updates the price on a WooCommerce product.',
    'category'            => 'woocommerce',
    'input_schema'        => array( /* ... */ ),
    'permission_callback' => fn() => current_user_can( 'manage_woocommerce' ),
    'execute_callback'    => fn( $args ) => update_post_meta( $args['product_id'], '_price', $args['price'] ),
    'safety' => array(
        'destructive'       => true,
        'requires_approval' => false,
        'snapshot'          => fn( $input ) => array(
            'post_meta' => array( $input['product_id'] => array( '_price', '_regular_price' ) ),
            'options'   => array( 'woocommerce_last_price_change' ),
        ),
    ),
) );
</code></pre>
<h4>Documentation</h4>
<p>Full plugin-author documentation lives at the GitHub repo: https://github.com/ibrahimhajjaj/abilityguard</p>
<h3>Source Code</h3>
<p>The full source for Tessera, including the unminified React source for the admin app, lives on GitHub: https://github.com/ibrahimhajjaj/abilityguard</p>
<ul>
<li>The admin bundle <code>assets/admin.js</code> is compiled from <code>assets/admin.jsx</code> (React + JSX, no preprocessor magic beyond JSX).</li>
<li>The bundler is <a href="https://esbuild.github.io/" rel="nofollow ugc">esbuild</a>, configured in <code>scripts/build.mjs</code>.</li>
<li>To rebuild the admin bundle from a fresh checkout, run <code>npm install</code> once, then <code>npm run build</code> whenever <code>assets/admin.jsx</code> changes. This regenerates <code>assets/admin.js</code> in place.</li>
<li>The release zip published to the WordPress.org directory is produced by <code>scripts/build-release.sh</code>, which excludes development artifacts (tests, examples, build configs) but keeps everything required for the plugin to run.</li>
</ul>
