Versions and integrity
Every page here carries a digest of its own source and a link to its history. Here is what those values mean, how to check them without taking my word for it, and the index of every page on the site.

What the footer means
Four values at the foot of every page; an unstamped page shows no digest row. Prices are stamped the same way: Principal examination $425/hr, full schedule.
| Field | What it is | What this does not establish |
|---|---|---|
| PAGE | The document's canonical path. | Not that an intermediary left the delivered page unaltered. |
| REVISED | Last substantive revision. | Not that no edit followed it; the history can contradict me. |
| SHA-256 (SOURCE) | Digest over the source below the front matter, from a tool in the public repository. | Not who wrote the text, when, or whether it is true. |
| prior versions | Commit history of that one file. | Not that the history is complete; I hold the repository. |
Checking it yourself
git clone https://github.com/wirewalktech/forensics-wirewalk- Every page:
python3 tools/stamp.py --checknames any file whose digest does not match. - One page, none of my code:
awk 'f{print} /^---$/{n++; if(n==2) f=1}' versions.html | shasum -a 256
Must equal the footer digest and front-matter content_sha256.
A match proves one thing: the checked source body is byte for byte the source that was stamped. The digest does not cover front matter, shared layouts, styles, or service prices loaded from the ordering system. A mismatch usually means I published without stamping — my failure, what this check catches. It does establish this is not the stamped text.
What it is not
Not a timestamping authority, not notarization, and no evidence about any examination or opinion of mine — test those against the method and the limits. Nor does it protect you against me: I compute the digest and hold the repository. Clone any term that may matter later.
Index
An identifier is never reused. A withdrawn page leaves this table, not the history.

If something does not match
A digest that fails, a version that did not move when a price did, a page with no row above: tell me. Call 917-217-7975 or use the form on contact. Reporting a defect creates no engagement. Same number for the work.
