ANS-104 is the Arweave / Bundler data item format. The wire shape +//! per the spec at +//! +//! is a binary frame (not the JSON projection). The JSON shape +//! (base64url fields, etc.) is a separate ergonomic layer; the +//! canonical artifact identity (`base64url(SHA256(signature))`) and +//! the deep-hash signing input are derived from the binary form. A +//! signed data item is what an Arweave gateway serves from +//! `GET /`: parsing the response, verifying the signature +//! against the persisted `node_did`, and only then trusting the +//! embedded cert is what `verify_anchor` in `arweave_v2.rs` does. +//! +//! The Arweave 2.0 deep-hash is the SHA-384 recursive list/blob +//! construction. The on-wire id is +//! `base64url(SHA256(signature))` — a separate, deterministic hash +//! derived from the signature, not from the deep-hash. Comparing +//! this id to the requested URL id is the artifact-identity check +//! the team memory `verify-against-artifact-id-not-signer.md` +//! requires: a node key signs many data items, so a valid signature +//! only proves who signed the response, not that it is the item the +//! caller asked to verify. +//! +//! ## Spec format (binary) +//! +//! Quoting the ANS-104 spec verbatim, the DataItem binary frame is: +//! +//! > ```text +//! > signature type (2 bytes, little-endian) +//! > signature (variable, sigSize(sigtype)) +//! > owner (variable, ownerSize(sigtype)) +//! > target (1 byte presence || optional 32 bytes) +//! > anchor (1 byte presence || optional 32 bytes) +//! > number of tags (8 bytes, little-endian) +//! > number of tag bytes (8 bytes, little-endian) +//! > tags (Avro array, ZigZag VInt lengths — see §1.3.1) +//! > data (variable) +//! > ``` +//! +//! The presence flag for the optional `target` and `anchor` fields is +//! `1` for present, `0` for absent. Signature and owner lengths are +//! per the configured `signature_type`. The signature_type values +//! defined by the spec are Arweave (1), Ed25519 (2), Ethereum (3), +//! Solana (4); see [`signature_size`] / [`owner_size`] for the +//! concrete byte widths. +//! +//! ## Deep-hash (the signing input) +//! +//! The signing input is a 7-element recursive deep-hash (per the +//! spec's `getSignatureData` / §2.2): +//! +//! ```text +//! deepHash(blob) = SHA384( SHA384("blob" || dec(len(blob))) || SHA384(blob) ) +//! deepHash(list) = foldLeft(SHA384("list" || dec(len(list))), items, +//! (acc, item) => SHA384(acc || deepHash(item))) +//! deepHashItem(item) = deepHash([ +//! "dataitem", +//! "1", +//! signature_type, // raw 2-byte little-endian +//! owner_raw, // raw bytes (NOT base64url-decoded) +//! target_raw, // empty buffer if absent +//! anchor_raw, // empty buffer if absent +//! tags, // NESTED [[name, value], ...] (NOT pre-hashed) +//! data_raw, // raw bytes +//! ]) +//! ``` +//! +//! The signature is over the raw 48-byte deep-hash output. `tags` is +//! the nested `[[name, value], ...]` form, NOT pre-hashed — the +//! deep-hash primitive walks the tree recursively via +//! [`deep_hash_chunk`]. +//! +//! The round-2 implementation (8-element fold with pre-hashed tags) +//! was wrong against this spec: items signed under it did not verify +//! on a standard bundler/gateway. The pin for the corrected shape +//! is the test `dataitem_matches_arbundles_golden_vector` against an +//! `arbundles` 0.10.x fixture captured in +//! `scripts/ans104_golden.mjs`. + +use anyhow::{anyhow, bail, Context, Result}; +use base64::{engine::general_purpose::URL_SAFE_NO_PAD, Engine as _}; +use ed25519_dalek::{Signature, Verifier, VerifyingKey, PUBLIC_KEY_LENGTH}; +use serde::{Deserialize, Serialize}; +use sha2::{Digest, Sha256, Sha384}; + +/// The signature type byte for Ed25519.
