OpenAI's Navier–Stokes claim drew questions about credit and whether Buckmaster's Codex prompts influenced it; its September 10 update says prompts in the two months before the September 8 announcement could not affect it.
Probes for percent-encoded traversal hit the cohttp maintainer's logs 10 minutes after the fix PR opened. Mandiant now puts mean time-to-exploit at -7 days, VulnCheck's data disagrees.
MHS is Anthropic's driver standard for agents running lab hardware. What it standardizes, where MCP sits underneath, and the numbers QuEra, CMU and Genentech reported.
Traced across 31 blog posts and 464 Hugging Face repos: Qwen's capybara debuted Oct 11, 2024, hit blog banners in Jan 2025, and its own edit prompts all say 'the bear'.
Claude Code's isolation: 'worktree' subagents were fixed for reaching into the parent checkout four times, across releases from 2.1.203 to 2.1.222, with the documented scope shifting each time. I lay out what git -C, GIT_DIR, and destructive git commands each broke, from the official release notes.
MCP 2026-07-28 drops initialize, session IDs, and SSE resume; Sampling, Roots, and Logging are deprecated. I wrote minimal servers for both specs and diffed them with curl.
Verified in SymPy: the 3-variable map from Alpöge's post has constant Jacobian determinant −2 yet sends three points to (−1/4, 0, 0). What changes for n ≥ 3 and what stays open.
Fitted Anthropic's jacobian-lens on Qwen3-4B-Instruct-2507 (4090, 51 min, ~1 USD), then read a layer-swapped SFT corrector: outputs pass through while hidden states diverge to cos 0.88.
Swap 'spider' for 'ant' in Claude's mid-layers and 8 legs becomes 6. Anthropic's global workspace paper, the J-lens readout, eval-awareness detection, and its limits.
Anthropic disabled Fable 5 and Mythos 5 for all customers on June 12, 2026. US export controls, foreign-national employees, AI Safety gaps, Microsoft limits, and the shaky Opus 4.8 fallback.
Claude Code sometimes emits a stray court token and raw <invoke> as plain text instead of running Read/Edit/Bash — a malformed tool call that never executes. How to tell it from a hung shell or a 'could not be parsed' error, on long Opus 4.8 sessions.
Reading Anthropic's postmortem and the DEV operational report in the same week reveals that Claude Code's quality degradation and Max weekly quota exhaustion are not separate incidents—they're two sides of the same quality×cost design decisions. A timeline and operational priority walkthrough.
