Addendum ships as one auditable HTML file. To confirm the copy you are running is exactly
the code that was published, hash your copy and compare it to the table below. The in-app
Settings → Privacy you can verify screen walks through this and also shows the live
Content-Security-Policy (connect-src 'none') that structurally blocks all network access.
On a Mac or Linux computer, in a terminal:
shasum -a 256 index.html
The output must match the SHA-256 for your version exactly. (The same table is recorded as
RELEASE-MANIFEST.md alongside the source.)
| Version | Schema | index.html bytes | SHA-256 | Date (UTC) |
|---|---|---|---|---|
