MBTI64-ZH32-EN32-V8_5-V5-RUNTIME-DUPLICATE-SECTION-SUPPRESSION-01

[fermatmind]

What changed

• Suppress legacy MBTI64 personality sections from the public API when V8.5/V5 first-class sections are present.
• Sanitize V8.5 module bodies at runtime so visible Evidence boundary: blocks are not emitted in body_md or payload_json.body.
• Stop newly promoted V8.5 modules from appending evidence/source ledger text into visible body copy while preserving evidence in payload metadata.
• Added focused regression coverage for V8.5 public section suppression, evidence metadata preservation, and legacy compatibility when V8.5 sections are absent.

Why

The repaired V8.5/V5 package is live, but public runtime still exposes both first-class V8.5 sections and old legacy sections. English pages also surfaced repeated Evidence boundary: body text. This PR keeps backend CMS authority intact while cleaning the public API/main reading path.

Validation

• php artisan test tests/Feature/Console/PersonalityMbti64CmsRevisionPromoteCommandTest.php --filter='test_write_promotes_only_fixed_v8_5_v5_bilingual_sixty_four_subset|test_public_detail_keeps_legacy_sections_when_v8_5_sections_are_absent' --display-warnings
• php artisan test tests/Feature/Console/PersonalityMbti64CmsRevisionPromoteCommandTest.php --display-warnings
• bash scripts/ci_verify_mbti.sh
• php artisan route:list --path=api/v0.5/personality
• git diff --check

Intentionally deferred

• No CMS writes.
• No live promotion.
• No publish/index/search.
• No sitemap/llms mutation.
• No frontend fallback content.
• Production deploy and runtime smoke remain separate gated tasks.

Repository rule impact

Backend public API remains the content authority. This PR narrows runtime response shaping only; it does not introduce frontend editorial content or replace CMS/backend authority.
