The Supreme Court rules geofence warrants need Fourth Amendment protection; Anthropic ships a cheaper Sonnet 5 the same day a researcher finds Claude Code hiding marks in requests; and Europe's digital ID leans on Google and Apple.

The Fourth Amendment reaches the geofence

The US Supreme Court ruled 6-3 in Chatrie v United States that geofence warrants, which compel a company to hand over every device inside a drawn area and window of time, must clear Fourth Amendment protections. Writing for the majority, Justice Elena Kagan held that people do not voluntarily surrender their location by carrying a phone that logs it, rejecting the reasoning that let police treat location history as freely shared business records. Privacy groups had warned that a geofence can sweep up everyone near an abortion clinic, a protest, or a recovery meeting; the ruling makes that dragnet a search, not a routine subpoena.

Anthropic, two ways

Anthropic released Claude Sonnet 5, which it says narrows the gap to its Opus models on agentic coding and tool use at $2 per million input tokens and $10 output through August 31, then $3 and $15, with cybersecurity safeguards on by default after it measured slightly higher partial-success rates on cyber tasks than Sonnet 4.6. The same day, a researcher reported that the Claude Code binary marks requests steganographically, swapping ordinary apostrophes for look-alike Unicode and nudging date strings to encode hidden bits, gated on checks for certain timezones, API base URLs, and AI-lab keywords held as a base64 string XOR-decoded with the key 91. The likely purpose is spotting unauthorized resellers and gateways; the effect is a developer tool with broad local access writing invisible marks into its user’s traffic.

Sovereignty and silicon

Two stories turn on who controls the substrate. A report from Waag finds the EU’s digital identity wallets leaning on Google’s Play Integrity and Apple’s equivalent to attest devices, which excludes de-Googled Android and the open attestation APIs that exist; Switzerland dropped Play Integrity over data-protection concerns while the EU reference framework still recommends it. Meanwhile South Korea committed about $1 trillion to memory fabs and humanoid robots, $585 billion of it for Samsung and SK Hynix plants meant to double the country’s DRAM output within five years, with Hyundai set to mass-produce Boston Dynamics robots.

What to watch today

  • Ornith-1.0, an MIT-licensed family up to a 397-billion-parameter mixture of experts, claims top open-weight results on Terminal-Bench 2.1, SWE-Bench, and NL2Repo by training the agent scaffold alongside the solutions; independent runs will settle whether it holds.
  • Whether Anthropic explains the Claude Code marking, and how other agent vendors handle client-side telemetry with the same local access.
  • South Korea’s DRAM expansion against a memory market already tightening under AI demand.
