Yoast's wpseo_schema_webpage_type filter passes ['WebPage'] (array) on every singular page. The v0.6.0 retype_to_medical_webpage() signature was strict string, causing TypeError → HTTP 500 on ALL singulars under strict_types=1. Secondary bug: enrich_webpage_piece compared 'WebPage' === $piece['@type'] but @type is an array, so MedicalWebPage enrichment never injected. Fix: - retype_to_medical_webpage: string|array param + return (PHP 8.1+ union) - enrich_webpage_piece: normalise @type to array before in_array() check - Add tests/unit/test-jsonld-webpage.php: regression tests with array input for both code paths; fail against v0.6.0, pass after fix - Bump version header + PR_CORE_VERSION constant to 0.6.1 - CHANGELOG entry under [0.6.1] Agent-Session: jsonld-webpage-typefix v0.6.1
