Every LIFETIMEBESS deliverable ships as an evidence package: the report, the data extracts and a manifest listing the SHA-256 of every file — signed with Ed25519 under a published key. Anyone — your lender, your insurer, opposing counsel — can verify it on this page, offline, forever.
Drop the whole package (manifest.json, manifest.sig and the files) — or a single file to get its SHA-256. Everything is computed locally by your browser via WebCrypto.
The manifest format is deliberately boring and deliberately open: JSON, SHA-256 and Ed25519. No blockchain, no proprietary viewer, no vendor lock-in. Any party can implement it; any party can verify it.
| spec | LTB-Evidence-Manifest/0.1 |
| files[] | path, SHA-256, size of every deliverable |
| asset / period | what the evidence covers |
| engine / seed | the exact model version and random seed — every result reproducible |
| key_id | which published key signed it |
| manifest.sig | detached Ed25519 signature over the manifest bytes |
You do not need this page. With our published key:
Published public key (Ed25519, raw, base64) — key_id ltb-2026-08:
Keys are published here with overlapping validity windows, so evidence outlives any single key — and outlives us. RFC 3161 trusted timestamping is being added to issued packages; the sample above is signed, not yet timestamped.
