Efficiency Heating & Cooling — fact sheet version history
What this page is. A published version history of the fact sheet that Efficiency Heating & Cooling uses to answer questions from AI assistants. Every version is hashed and listed here, superseded versions included, so the history is tamper-evident: change a byte in any published version and its fingerprint stops matching.
Who publishes it. AIgentCandor, a product of Sapid Agency. We measure how AI agents read a business website, put the answers they are missing where they actually read, and measure again. Run the free audit on your own site.
What it never does. It does not verify anyone's identity, and it does not attest that the facts are true. It records what a business signed off, and when.
Current version v10, attested by Michael Emery, Sapid Agency (site management for Efficiency Heating & Cooling) on 2026-09-08.

Every row reading PENDING_ANCHOR means the hash is final and size-checked but nothing has been broadcast to a public ledger yet; anchoring a version later changes nothing about it. A version file, once published here, is never edited — a new version is a new row.
This page is generated by AIgentCandor from the profile the business signed off. It is a record of what the business attested and when — not our endorsement of the facts, and never a verification of identity. The machine-readable copy is eheatcool.com.stamps.json; the vocabulary is defined in the glossary.
