VAX Proof Stamp (GitHub Ledger) Codeberg
On publish/update, this plugin hashes your post body (SHA-256) and appends a JSON line to a public GitHub repo (a simple `ledger.jsonl`). It stores the commit SHA in post meta and provides a `[vax_proof]` shortcode that links to the exact commit.

Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from Codeberg with WP-CLI:
wp plugin install https://codeberg.org/vibeaxis/vax-proof-stamp/archive/main.zipNo built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.

Why
Receipts vibes. Public, third-party timestamp + immutable history = trust.
Install
1. Copy to /wp-content/plugins/vax-proof-stamp/ and activate.
2. Preferred: define constants in wp-config.php:
php
define('VAXGHTOKEN', 'ghpxxx'); // fine-grained, Contents:RW, repo-scoped
define('VAXGHOWNER', 'YOURUSER');
define('VAXGHREPO', 'vibeaxis-proofs');
define('VAXGHPATH', 'ledger/ledger.jsonl');
define('VAXGHBRANCH', 'main');
Or set them under Settings → VAX Proof Stamp (dev only).
3. Add [vaxproof] where you want the stamp, or echo it in your template.
Format
Each line in ledger.jsonl:
{"url":"https://…","id":123,"title":"…","sha256":"…","ver":"2025-08-26T01:23:45Z","algo":"sha256(canonicaltextv1)"}
WP-CLI
wp vax-proofs backfill — stamps all published posts that don’t have a commit yet.
