archive-b

CoNET-DLE Archive-B TypeScript MVP

Independent archive implementation. It imports no code from another implementation.

Commands

npm ci
npm test
npm run build
npm run conformance
CORPUS_PATH=/path/to/later-corpus.json npm run conformance

The CLI also accepts newline-delimited JSON on stdin and writes exactly one JSON response per request:

{"id":1,"op":"corpus.run"}
{"id":2,"op":"da.encode","bodyHex":"0x00010203"}

Supported operations are corpus.run, ssz.proposal, ssz.vote, da.encode, da.reconstruct, and lifecycle.advance.

Safety boundaries

• Proposal/Vote serialization is fixed-width SSZ with strict field and byte-length checks.
• Tendermint lock/valid transitions call a durable-transition adapter before returning any vote.
• DLEW WAL frames use monotonic sequence numbers and SHA-256 payload/frame checksums. Corrupt or incomplete tails fail closed into non-voting recovery; they are never silently truncated.
• dle.rs.v1 is the frozen systematic GF(2^8) RS(7,4) matrix and fixed eight-leaf SHA-256 DA tree.
• Group admission requires five disjoint voters plus two disjoint, readiness-proven standbys.

The canonical v2 corpus freezes certificate SSZ/references, coordinator selection, DLEW frames, RS(7,4), DA roots, Tendermint state transitions, and the 5+2 lifecycle. The immutable v1 corpus remains supported through CORPUS_PATH; its report lists the dimensions that v1 did not freeze. This is an MVP, not a production signer: the final SSZ-to-EIP-712 signature wrapper, production networking, key custody, and crash-injection integration remain outside this package.
