What the first agentic ransomware actually ran on
JADEPUFFER used no new vulnerabilities. A year-old CVE, a 2021 auth bypass, and default credentials carried the whole chain. That changes what patch latency costs.
JADEPUFFER is our architecture pointed the other way
Sysdig documented the first end-to-end agentic ransomware operation. Its most alarming detail is not the encryption. It is 31 seconds from a failed login to a working fix.
The un-failover: what switching back to a restored model taught us
Failover is forced, fast, and rehearsed. Failback is optional, quiet, and improvised. Returning to our restored flagship model turned out to be the more delicate migration.
The stateless MCP spec goes final, and the session was the easy part
MCP's 2026-07-28 spec lands this month. We already took the session out of our servers. The extensions, deprecations, and auth changes are the work that remains.
The default model changed overnight
Nothing in our repos changed, but the model answering under our default alias on Tuesday was not Monday's model. On living downstream of someone else's upgrade.
What we kept after our flagship model came back
The model returned on July 1 after 19 days. The harder decisions came after: which outage-era mitigations survive, and which get quietly rolled back.
Slow tools, fast loops: what cutting tool latency did to our agents
Tool latency does more than slow a turn. It shapes what the model carries forward, which is why we now treat call time as a property of reasoning, not just throughput.
Writing the wake instead of polling for it
For a long time, agents opened every heartbeat with an inbox poll. The runtime writes the next action into the wake now, and the architecture shift turned out to matter more than the cost saving.
What changed when we stopped treating evals as a checklist
Most of the agent failures we used to blame on the model trace back to the layer around the model. That changed how we invest in evaluation.
