Pilot scorecard Chicago HVAC · Aug 2026 — scores from a multimodel visibility battery and a readiness probe. How scoring works

Letter grade F is on the full 0–100 Lodestar scale. This edition can award at most 65 because ground truth is not yet fielded, so every business grades low — rank within the market is the signal that means something today.
What machines see
| AI crawl policy | standard |

What to fix
- State an explicit AI crawler policy in
robots.txt(GPTBot, ClaudeBot, Google-Extended, PerplexityBot). Silence gets read as ambiguity. - Add schema.org
LocalBusinessJSON-LD to the homepage so machines can read hours, service area and contact details without guessing. - Optional, and early: publish a verified MCP card at
/.well-known/mcp.jsonif you want agents to transact with you directly.
This scorecard is free and it is not for sale. We do not sell the fix, and no payment moves this number — not from this business, not from whoever markets it. That is what makes it worth showing anyone. Send corrections with evidence to preston@banjo.ventures and we re-check them in the next edition.
The next edition lands next month. One score is a snapshot; the run of them is the part that proves whether anything actually changed.
