# Strands Decider 2B or Jev — placement worksheets

Companion artifacts for the FactualMinds post
**Strands Decider 2B or Jev: keep closed-set decisions inside the account**.

**Public URLs:** `https://www.factualminds.com/examples/architecture-blog-2026/strands-decider-vs-jev/{path}`

## Demo disclaimer

These files are a **placement worksheet and a sourced number table**. They are not a production deploy, not a live TypeSafe call, not a loaded Decider weight, and not an anonymized client engagement.

- No API key. No model download. No socket.
- Do not treat the CSV as a benchmark FactualMinds ran.
- Every numeric cell names the page it came from and the date that page was read: **16 Oct 2026**.
- First-party platform signals cited in the post (Gateway ~180→95 ms canary, AgentCore ~$791/mo at 50K sessions) come from earlier published FactualMinds AgentCore posts. They are not Decider results and not Jev results.
