✅ Docs-Ops Gate — MDX validity PASS

checked 32 .mdx files; 0 with problems

❌ Docs-Ops Gate — SDK page style FAIL

checked 6 SDK .mdx files; 1 with style problems

SDK style problems (block the merge)

SDK style mode: 6 changed social-plus-sdk .mdx file(s) vs origin/main

FAIL social-plus-sdk/chat/engagement-features/unread-status/channel-unread-count.mdx
    - line 18: Parameters table needs a `Platforms` column because the page documents platform-dependent behavior

checked 6 SDK .mdx files; 1 with style problems

⚠️ Drift + doc-as-test SKIPPED — SDK_READONLY_PAT secret is not configured, so the private TS SDK can't be checked out. MDX validity above still gates. Add the secret to enable the full API-accuracy layer (see .docs-ops/CI_GATE.md).
