seo-engine: launch desk 8 Oct 01:00 IST, Claude Haiku 5.5

[chaitanyagiri]

What changed

One new page from the launch desk.

• /blog/claude-haiku-5-5/: Anthropic announced Claude Haiku 5.5 on 7 Oct 2026. The Hacker News thread had more than 300 points on 8 Oct. "claude haiku" has 2,900 searches a month at difficulty 32 and "claude haiku 4.5" has 2,400 at 21 (OpenSEO, 8 Oct 2026); "claude haiku 5.5" has no data yet. 1,151 words, four bright scenes and a title card.
• One link to it from claude-code-subagents-vs-multi-agent-harness.

Checks

• Gate: pass on the new page with media and motion checks on. Build and node tools/check-release-links.cjs: pass.
• claude-code-subagents-vs-multi-agent-harness fails the gate on length alone, before this change (1,642 words) and after (1,649). Only one sentence was added.
• Independent fact review, round 1, against the raw announcement: every price, benchmark cell and quote matched; fail on three wording points (a dropped "slightly" and two opinions not marked as ours). I applied the three fixes word for word. Round 2, by a different reviewer: pass.
• Benchmark figures are labelled as Anthropic's own and the page says we did not run them and have not tried the model. It says where Haiku 5.5 trails Sonnet 5.5.
• Every number and label shown in the scenes was checked against the post body by me.
• Scenes swap in on the built page in headless Chrome (4 of 4). Tap and arrow actions were not exercised in a browser. Not tested: Safari, Firefox, a real phone.
• This branch, seo-engine: day 09 PM, Mistral Large 4, two versus pages, OpenDots on the dots alternatives page #704, seo-engine: launch desk 7 Oct 13:00 IST, OpenAI Decisions API #708 and seo-engine: day 10 PM, Codex vs Cursor, Gemini CLI vs Claude Code, grok-bot-pricing fix #709 all add to media.json and the built blog, so after one merges the others need a rebase. I will do it.
