## Inclusion-criteria filter applied

Per `CONTRIBUTING.md`:

> **In:** First-of-a-kind capability, new economic point, new context-window class, new distribution model, new modality-fusion architecture; cross-vendor convergence; scale milestones that shift the interop story; productizes a research idea.
> **Out:** Version bumps, routine spec revisions, vertical products that don't introduce a primitive.

This wave proposes **3 new Tier 1 timeline entries + 1 augmentation** of an existing April entry.

---

## TIER 1 — New entries (3)

### Entry 1 — May 6, 2026 — Code with Claude: Dreaming, Outcomes, Multiagent Orchestration

**Insertion point:** New entry, chronologically after the April 28, 2026 — AgentFlow / late-April research cluster. First entry of the May 2026 sub-section.

**Why include:** Three new primitives on the Managed Agents substrate, each a first-of-a-kind:
- *Dreaming* — first commercialized between-session learned-memory curator (productizes the consolidation pattern that 2025 academic work only described).
- *Outcomes* — productizes the Ralph loop / CATTS uncertainty-steered iteration pattern as an API contract.
- *Multiagent Orchestration* — first managed fan-out primitive with shared filesystem + persistent event memory.

Combined with April's pricing + memory + AWS distribution moves, this is the moment two of three frontier vendors sell a *learning, self-correcting, multi-agent* managed substrate.

**Proposed entry text:**

> ### May 6, 2026 — Code with Claude: Dreaming, Outcomes, Multiagent Orchestration
>
> At its annual developer conference, Anthropic shipped three new primitives on the Managed Agents substrate. **Dreaming** (research preview) runs a scheduled between-session job that reads recent sessions, identifies recurring errors and converged workflows, and rewrites the agent's persistent memory — productizing learned-memory consolidation as managed infrastructure. **Outcomes** (public beta) exposes a separate-grader self-correction loop: write a rubric, the agent iterates against a grader running in its own context window. **Multiagent Orchestration** (public beta) ships lead-agent-to-specialists fan-out with shared filesystem and persistent event memory. Harvey reported ~6x task-completion improvement with Dreaming in pilot. Combined with April's pricing + memory + AWS distribution, two of three frontier vendors now sell a learning, self-correcting, multi-agent managed substrate.

- VentureBeat, "Anthropic introduces 'dreaming,' a system that lets AI agents learn from their own mistakes" (May 6, 2026)
- The New Stack, "Anthropic will let its managed agents dream" (May 2026)

**Confidence:** High. Primary Anthropic blog + Simon Willison contemporaneous live coverage + two independent tech-press confirmations.

**Cross-chapter implications:**
- **Ch04 §4.6 (Three-Agent Architecture / self-healing memory lineage):** Dreaming is the first cloud-managed background memory curator; add as the productized counterpart to the leaked self-healing memory loop.
- **Ch06 (Agent Memory):** Add a *trainable-vs-curated* dichotomy under "Trainable Memory Modules" — Titans+MIRAS (gradient at inference) vs Dreaming (LLM-rewritten plaintext). These are now the two contrasting commercial directions for long-term agent memory.
- **Ch08 (AI-Assisted vs AI-Native / Velocity Paradox):** Managed Agents now bundle a learning loop, raising the bar for self-hosted alternatives.

### Entry 2 — May 6, 2026 — AWS MCP Server reaches general availability

**Insertion point:** New entry, **same day as Entry 1**. Place BEFORE Entry 1 in the timeline (chronologically same-day, narratively this is the MCP/infra ground floor and Code-with-Claude sits on top of the same substrate posture). The reading order is: AWS MCP GA (substrate consolidation) → Code with Claude (substrate primitives).

**Why include:** Scale milestone that shifts the interop story (15,000+ API operations through one authenticated server). First hyperscaler-blessed Skills deployment. The S3-like consolidation moment for MCP — moves the protocol from "many self-hosted servers" to "one managed endpoint at the cloud boundary."

**Proposed entry text:**

> ### May 6, 2026 — AWS MCP Server Reaches General Availability
>
> AWS shipped the first hyperscaler-managed remote MCP endpoint at GA: **15,000+ AWS API operations** exposed through one authenticated server, with IAM context keys for fine-grained access (no separate IAM permission required) and a sandboxed `run_script` tool for server-side Python. The release also adopts **"Skills over SOPs"** as the canonical agent entry point, making AWS the first hyperscaler to ship Skills (the Anthropic / OpenAI / Google open standard from December 2025) as production agent guidance. MCP moves from "many self-hosted servers" to "one managed endpoint at the cloud boundary" — an S3-like consolidation moment for the interop layer.

**Sources:**
- AWS What's New (primary): https://aws.amazon.com/about-aws/whats-new/2026/05/aws-mcp-server/
- AWS News Blog: https://aws.amazon.com/blogs/aws/the-aws-mcp-server-is-now-generally-available/
- Techstrong.ai independent coverage (May 2026)

**Confidence:** High. Two AWS primary sources + independent secondary.

**Cross-chapter implications:**
- **Ch07 §"Timeline: From Launch to Linux Foundation" / 2026 (present):** Add as the scale milestone post-Linux-Foundation (Dec 2025) and post-97M-downloads (Q1 2026). The S3-like consolidation moment.
- **Ch05 §5.9 (Industry Convergence / Google Agent Skills Spec):** First hyperscaler-blessed Skills deployment confirms cross-vendor convergence (Anthropic + OpenAI + Google + now AWS).
- **Ch04 §4.9 (Cloud-Native Harness Primitives):** Harness boundary now includes a managed MCP edge.

### Entry 3 — May 7, 2026 — AWS AgentCore Payments preview (x402, Coinbase, Stripe)

**Insertion point:** New entry, immediately after Entry 1 (Code with Claude, May 6).

**Why include:** First managed payment primitive for autonomous agents. Inclusion-criteria match on "new primitive" (x402 as the value-layer analogue to MCP) + "cross-vendor convergence" (Coinbase + Stripe + AWS shipping a common stack). Coinbase's prior x402 traction (69k active agents, 165M transactions, ~$50M cumulative volume by late April) means the protocol had scale before the hyperscaler endorsement — AWS shipping a managed runtime is what turns "MCP for tools, x402 for value" into the first cross-protocol agent stack.

**Proposed entry text:**

> ### May 7, 2026 — AWS AgentCore Payments Preview (x402, Coinbase, Stripe)
>
> AWS announced the preview of **AgentCore Payments** — the first managed payment primitive for autonomous agents — built with Coinbase and Stripe. Agents connect a Coinbase CDP or Stripe Privy wallet, encounter an HTTP 402 response from a paid resource, and AgentCore handles the **x402** negotiation, stablecoin payment, and proof delivery without breaking the reasoning loop; session-level spending limits are enforced deterministically at the infrastructure layer. Coinbase's prior x402 traction — **69,000 active agents, 165M transactions, ~$50M cumulative volume by late April 2026** — meant the protocol had reached scale before hyperscaler endorsement, and AWS shipping a managed runtime turns "MCP for tools, x402 for value" into the first cross-protocol agent stack. Available in preview in us-east-1, us-west-2, eu-central-1, ap-southeast-2.

**Confidence:** High. Two AWS primary sources + open x402 spec + recurring AWS weekly roundup confirmation. Numerical traction claims (69k / 165M / $50M) sourced to user-supplied scope brief — citing AWS blog framing.

**Cross-chapter implications:**
- **Ch07 (MCP — Adopters / Protocol Landscape):** Add x402 alongside MCP and A2A as the agent-to-resource value layer. Frame as the FIRST cross-protocol agent stack ("MCP for tools, x402 for value").
- **Ch08 (AI-Assisted vs AI-Native / Velocity Paradox):** Payments-as-tool joins observability-as-tool as new sensor/effector classes.
- **Ch04 §4.1 / §4.9 (harness contracts):** New harness contract — spending budget enforced outside the model, deterministic infrastructure enforcement (not LLM-judged).

## AUGMENT — Append to existing April 7 Mythos entry

### Augment 1 — May 11, 2026 — GPT-5.5-Cyber Trusted Access (Glasswing pattern reproduces)

**Insertion point:** Append a 1-2 sentence note to the existing `### April 7, 2026 — Claude Mythos Preview` entry in Ch11.

**Why include:** Validates the vetted-coalition-for-dual-use-AI pattern by showing a second instance — same shape (gated tier, named coalition partners, mandatory security posture) by OpenAI on a different model line. Once a distribution model reproduces across vendors, it stops being a one-off and becomes a category.

**Proposed augment text (append to April 7 entry, after the existing breach paragraph):**

> The Glasswing distribution pattern — a vetted coalition for dual-use AI — got a second instance on May 11, 2026 when OpenAI shipped **GPT-5.5 with "Trusted Access for Cyber,"** extending availability through a coalition of EU partners (Deutsche Telekom, BBVA, Telefonica, Sophos, Scalable Capital) with required Advanced Account Security enforcement. The pattern reproducing across vendors confirms that vetted-coalition distribution for dual-use AI is now an industry convention, not a one-off.

**Sources:**
- OpenAI (primary, may return 403 to crawlers): https://openai.com/index/gpt-5-5-with-trusted-access-for-cyber/
- CNBC (May 11, 2026): https://www.cnbc.com/2026/05/11/openai-eu-cyber-model-anthropic-mythos-gpt.html
- UK AISI evaluation blog

**Confidence:** Medium-high. OpenAI primary URL may 403 against crawlers (user-flagged caveat in scope); CNBC secondary is the load-bearing source. UK AISI evaluation reinforces the safety-eval-as-product framing.

**Cross-chapter implications:** None outside Ch11 — this is timeline-only augmentation.
