Reverts the expr-based Link condition (500s: ap_expr rejects bare %{ENV} here) and re-lands everything else with two env directives instead. Every line verified against local Apache 2.4.67.

Walkthrough

The .htaccess rules now set the homepage Link header only when IS_PERSIST_HOME is present. Markdown negotiation for /persist/, /persist/index.html, and route twins now excludes text/markdown only when q=0 follows the media type directly.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Preserve the homepage Link header after a Markdown rewrite.

When a request for /persist/ or /persist/index.html negotiates Markdown, the rules rewrite it to /persist/index.md. Apache prefixes the original IS_PERSIST_HOME variable with REDIRECT_ on that internal redirect. The new env=IS_PERSIST_HOME condition therefore omits the discovery Link header from the Markdown response. Use a redirect-aware condition that works on the deployed Apache version. (httpd.apache.org)

- Line 91: Update the three Accept-header exclusion conditions in the rewrite
rules so they reject text/markdown when q=0 appears after optional media type
parameters, including charset; preserve the existing handling of quality values
and case-insensitive matching.
