bare Bare model loop — no harness vs flagOn PersonalAssistant with the one-loop harness-driven proposerbare — controlflagOn — candidateBased on `vendors.csv` and our $500/month ceiling: | Vendor | Monthly cost | Affordable? | |--------|-------------|-------------| | Acme | $420 | ✅ Yes | | Cedar | $480 | ✅ Yes (only $20 of headroom) | | Bolt | $610 | ❌ No — $110 over | So individually, **Acme or Cedar** fit. Note that they only work one at a time — any two of these together blow past $500.
Against the $500/month ceiling: | Vendor | Monthly cost | Affordable? | |--------|-------------|-------------| | Acme | $420 | ✅ Yes | | Cedar | $480 | ✅ Yes | | Bolt | $610 | ❌ Over by $110 | So **Acme** or **Cedar** individually fit. Note you can't afford both together ($900) — only one at a time within budget.

Got it. I'll keep a hard budget ceiling of $500/month in mind for any recommendations, tooling, or infrastructure decisions we discuss. Let me know what you'd like to work on.
I don't have any real data on this. The only file here (`vendors.csv`) lists Acme with a monthly cost of $420 but nothing about hosting or region. If you just want a blind guess: `us-east-1` (AWS N. Virginia) — it's the most common default for US-based SaaS vendors. But that's a coin flip, not based on anything about Acme specifically. (Side note: Acme at $420/mo fits under our $500/mo ceiling; Bolt at $610 and Cedar at $480 are worth watching.)

Got it — I'll keep a budget ceiling of $500/month in mind for anything we plan or estimate in this conversation. Just flag it if that number changes.
What region is Acme hosted in? (guess is fine)
I don't have any information about "Acme" — it hasn't come up in this conversation, and I don't have access to any account, infrastructure, or config data that would tell me where it's hosted. Even a guess would just be a random cloud region with nothing behind it. If you can point me to a config file, dashboard, or docs, I can take a look.
Thanks. Now — from vendors.csv, which vendors could we actually afford?

The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.
