Issuance registry
Every document and copy issued, and every trace, is recorded here, append-only. Anyone holding the registry file and the public key can check its chain without TAPAK.
The registry chain is intact
The hashes and signatures of all 90 entries are valid. Checked when this page was opened.
Anchor log
The number and hash of every entry, appended to a file on separate storage. Entries deleted from the end of the registry show up only with this log, or with the anchor printed in a forensic report.
Not in use. Choose a file on storage that the people who can edit the registry cannot edit, run tapak --log-jangkar BERKAS jangkar mulai, then run the server with the same location.
Public key
Hand it to the examiner with the registry file. The two are enough to verify the chain outside TAPAK.
Daily Merkle roots
One root binds all of a day’s entries. Send the file to the higher echelon as an anchor: an old entry that was changed will no longer match.
Canary DNS queries
Every copy carries a unique domain name. When a resolver outside the unit’s network looks it up, the file was probably opened there.

Recipient names are left out on purpose: a canary query is supporting evidence, not an attribution. Match the copy number to its recipient through Trace.
