VerifyBundle: durable records anyone can check.
VerifyBundle is the consumer product built on the same SEP construction and the same verification rules, checked by its own pinned verifier. Seal a file or a note in your browser and get an offline-verifiable record. Its durable path is post-quantum today, so the record stays tamper-evident for decades. Same construction, same checks, a different audience.
One standard, two defaults
The same SEP construction and the same offline checks, tuned to two threat models.
Runtime governance
Seals each decision into an evidence bundle that verifies offline against the published format. Defaults to Ed25519, the zero-dependency operational default; the post-quantum composite is a first-class selectable profile.
How AGA worksDurable consumer evidence
Seals a file or a note client-side into a portable record. Post-quantum in the durable path, today, for multi-decade tamper-evidence. Browser-signed, stores nothing.
verifybundle.comWhat a record proves
Offline verification
Anyone checks a record on their own machine, with no network access and no callback. Built for air-gapped use.
Tamper-evidence
Any change to the sealed content or the receipt makes verification fail. The record proves it has not changed since sealing.
Chain integrity
Hash-linked receipts make any reordering or deletion within the chain detectable.
Sealing timestamp
Each record carries the time it was sealed (the producer's signing-time clock, not a certified time authority).
What it does not prove
A passing check proves your data is unaltered since you sealed it, and the time it was sealed. The seal itself resists a quantum adversary's forgery. It does not prove who sealed it, or that the contents are true (the seal is signed with an ephemeral, anonymous key). Anyone can re-derive the check offline.
The offline verifier is pinned and dated. See the dated, offline re-derivable trust root on verifybundle.com.
