Day 32 morning run of the content engine: the 29 Oct daily brief and a same day launch page for Gemini 4 Carbon, which Google announced on 28 Oct at 17:00 UTC (more than 860 points on Hacker News).

What changed

• New: gemini-4-carbon (launch slot, 962 words). Who can use it (a subset of cyber defenders first, then trusted partners through Fairwind, then developers, with no date), the introductory price ($2 in, $10 out per 1M tokens, then $4 and $20), a dated Argon price table, and a Carbon vs Argon table built from Google's own figures, each one attributed. Title card plus 3 scenes (podium, ticket, scale), one tap interaction each. The Carbon launch checks started at the 01:00 launch desk check, but that session ended mid run, so the page ships in this run.
• New: agent-tools-today-2026-10-29 (daily brief, 1,126 words). Launches: Gemini 4 Carbon, Copilot connectors, shared Copilot Automations. Skills: Impeccable, Superpowers, Expo skills. Moves: OpenCode 2.2.1, Goose 1.57.0, Qwen Code 0.26.3. Rising: Macro, BAMA, vvv. Arguments: the Claude Code status line token gist, DAYJOB: Tax, and "Here be monsters". One cork board scene; it reuses the series hero.
• gemini-4-argon: a dated link to the new page, the current house line, and "top model on general release" in place of "newest top model".
• media.json: two entries, inserted before gemini-4-argon, away from the seo-engine: day 30 AM, brief 27 Oct and Claude Cowork alternatives #795, seo-engine: day 30 PM, Pi vs Claude Code plus two fact refreshes #797 and seo-engine: day 31 AM, brief 28 Oct, ChatGPT Dots vs Claude Cowork and Codex vs ChatGPT #799 hunks.
• docs/ rebuilt.

Checks

• gate.mjs: PASS on all three changed posts (gemini-4-argon run with --no-media --no-motion --no-backlink).
• One independent fact review: FAIL on 6 lines (Carbon), 2 (Argon) and 5 (brief); PASS on the media alt. All 13 are fixed with the reviewer's wording. The main fixes: the "without guardrails" qualifier now covers only the cyber benchmarks; Argon's access and price dates are credited to the right pages; "introductory" and "gradually" restored; publish dates added to three argument items from 26 and 27 Oct; Agent Merge got its own source link.
• npm run build clean (425 files).
• OpenSEO credits used: 0. The OpenSEO connection is signed out, so this run has no Search Console row and no index watch. A same day vendor launch needs no demand check, and page 3 was skipped because it would need one.

The two new pages show a 404 in the before shots because they do not exist on main yet.

Open engine PRs: #795, #797, #799 and this one. All rebuild docs/, so the ones merged later may need a rebase. I will rebase them as they come up. The founder merges. Carbon is a same day launch, so merging this one first gets it live soonest.
