Name the world, write its seed, and choose only the rules you intend to preserve.
MANIFEST SYSTEM / DETERMINISTIC / LOCAL-FIRST
Give a world
memory that survives.
Describe the world, lock its laws, and produce a portable manifest with a browser-generated SHA-256 fingerprint.
ARCHIVE NODE01 / READYNothing leaves this browser until you export it.
TOOL / 001

Every output is derived from your inputs. No demo metrics, hidden server state, or fake deployment.

PROTOCOL / 002
A record you can reopen.
The method is deliberately small: normalize, fingerprint, export, verify.
Fingerprint
The browser canonicalizes the manifest and calculates a SHA-256 digest using Web Crypto.
Export
Download the complete JSON record. The file includes the source fields and fingerprint.
Verify
Recompute the hash anywhere. Matching input produces the same identity.
EVIDENCE / 003
Local records, not platform promises.
Generated with the browser's native Web Crypto API.
No account and no remote database are required.
Aevum prepares evidence; it does not pretend a transaction happened.
FAQ / 004
Questions before permanence.
Does Aevum upload my seed?+
No. The current release processes text and manifest data locally in your browser.
Is the manifest already on-chain?+
No. Exporting a manifest creates a verifiable local record, not a blockchain transaction.
Can two people verify the same world?+
Yes. The same normalized manifest produces the same SHA-256 fingerprint.
