ISSUE 391 — THE WEEK THE ASSISTANT BECAME AN ACTOR

A wire dispatch distilling a single late-May 2026 week of AI news into seven stakes — the second dispatch-format issue (368 was the first), stepping out of the "Agentic Substrates" series (388–390) for a dated, reactive week-in-review that bridges back to 390. The week's through-line: the field's centre of gravity moving from a machine that answers to one that acts, across four fronts at once.

The seven stakes

Each tied to something that landed between 5–23 May:

1. FIELD — an internal OpenAI model autonomously disproving an ~80-year-old geometry conjecture
2. MODELS — GPT-5.5 Instant becoming the ChatGPT default amid a dense release stack (Grok 4.3, Gemini 3.5 Flash / 3.1 Ultra, a subquadratic 12M-token model)
3. AGENTS — Google I/O reframing Gemini as a cross-platform actor + Microsoft Copilot Studio computer-use GA (the spine of the issue)
4. MONEY — the advertisement moving inside the answer (OpenAI Ads Manager, Google AI Search ads)
5. CAPITAL — Anthropic acquiring Stainless and the $200M Gates Foundation partnership
6. GOVERNANCE — regulators gaining pre-release early access
7. TASTE — discernment as what the week did not make cheaper

Identity

ivory stock + asymmetric-left + ink-spread ornament (dispatch-exclusive; deliberately breaks the 374–390 asterisk-stamp run) + brick accent (dispatch default) + FILED·WIRE seal + THE WIRE DESK postmark. Bulletin pull-quote + AP "— 30 —" terminator. Sources named in-prose per the dispatch contract; the filing flags itself as fast and partly unverified (esp. the math result, which awaits public verification).

Files

• src/content/issues/391.ts — new dispatch spread
• src/content/issues/index.ts — registered (LATEST_ISSUE → 391)
• src/content/issues/PUBLISHING.md — hygiene pass: §IV dispatch template ref 368 → 391, last-updated → ISSUE 391
• SCRATCHPAD.md — session entry

Verification

• npx tsc --noEmit and npm run build both clean (after npm install in the fresh container; tsconfig unchanged).
• Already deployed to gh-pages from the feature branch — live on kernel.chat. Merging here keeps main and the live site in sync so a future deploy from main doesn't overwrite 391.
