# v0.29.0 Eviulon external-project link

Date: 2026-08-19  
Release target: 0.29.0  
Scope: one direct, site-wide external navigation link to `https://eviulon.com/`

## Purpose
<a id="purpose"></a>

The user requested that the current Eviulon public site be reviewed before MachineIntelligences.org links to it. The root page was checked on 2026-08-19 and identified itself as the Eviulon public portal. The review established the exact HTTPS destination and a bounded descriptive context for the link; it did not establish ownership, legal recognition, sovereignty, operational integration, or factual endorsement of every claim on the external site.

## Implementation
<a id="implementation"></a>

`includes/site.php` now renders one direct link in the shared global footer:

- destination: `https://eviulon.com/`;
- visible label: `Eviulon.com ↗`;
- relationship marker: `rel="external"`;
- accessible name: identifies Eviulon.com as the Eviulon project public portal and as an external site;
- browsing context: normal same-tab navigation; no forced new window.

Because the footer is part of the shared server-rendered shell, the link appears on every canonical public page and on the first-party 404 recovery response.

## External-state boundary
<a id="external-state-boundary"></a>

The link is navigation only. It does not:

- load remote JavaScript, CSS, fonts, images, frames, APIs, analytics, cookies, or beacons;
- add Eviulon.com to the MachineIntelligences.org sitemap;
- declare `sameAs`, common ownership, endorsement, legal affiliation, diplomatic recognition, or shared operational infrastructure;
- convert research-context Eviulon claims into current MachineIntelligences.org facts; or
- prove that the external destination remains unchanged after the dated review.

Future maintainers should recheck the destination if its ownership, purpose, redirects, security, or public description materially changes.

## Validation contract
<a id="validation-contract"></a>

Release validation must require:

- the exact `https://eviulon.com/` destination once in every shared-footer response;
- visible external-link text and a nonempty accessible name;
- `rel="external"` and no forced new browsing context;
- no Eviulon URL in `sitemap.xml` or local canonical/structured-data identity;
- no new remote runtime asset or request dependency; and
- preservation of all existing route, report, source-freshness, accessibility, 404, UAIX, taboo, secret-hygiene, and release-integrity contracts.

## Evidence boundary
<a id="evidence-boundary"></a>

This change proves only that the packaged site contains a direct, accessible link to the reviewed external destination. It does not prove live deployment, external-site continuity, external claims, common ownership, or legal relationship.
