This page publishes verification records for Air Sense Environmental’s public AI and authority resources. Anyone can download them and check that a file we published is byte-for-byte what we released.
What the records show
- SHA-256 hashes of the exact bytes served for each listed URL at the capture time below.
- An OpenTimestamps proof that the release manifest existed by the time it was anchored in the Bitcoin blockchain.
- Internet Archive snapshots made independently by the Wayback Machine.
These records show that files existed and were unchanged. They do not by themselves prove that a statement is accurate, who wrote it, or that a third party endorses it.

ScoreDetect timestamp certificates
Nine pages also carry an independent ScoreDetect certificate. Each certificate records the SHA-256 of the page’s Markdown version (the index.md file listed above) and names the page as its source. A certificate shows that the content existed in that form at that time; it does not certify accuracy.

How to verify
- Download a file and compute its SHA-256 (for example
shasum -a 256 file), then compare it with the table. HTML is hashed as served by our origin; Cloudflare may add an analytics script for some visitors. - Install the OpenTimestamps client and run
ots verify release-2026-10-06.json.otsnext to the downloaded manifest. - The live integrity list for our static resources is at /authority-stack-manifest.json.
