Answers ADR 0002's open decision 2 (cross-chain-read trust model) and removes the manager/backend as the attestation authority: an open bonded submitter set, channel-typed evidence (guardian-signed consensus reads, TEE oracles, zkTLS, bare bonds), a diversity quorum with two-sided consumption, and bonded disputes that fail closed into the existing ADR 0002 halt machinery. Grounded in deep research (2026-06-10): HyperCore state is not commitment-anchored anywhere (kills anchorable ZK light clients today, hence diversified observation), Wormhole Queries is permissioned-request but trustless-verify with HyperEVM eth_call support, lzRead reaches neither HyperEVM nor Solana, Switchboard On-Demand is live/permissionless on Solana behind TEE-gated operators, and Solana's Groth16 substrate is production-ready (audited <200K CU verifier). Research-grade claims are labeled and listed for re-verification before implementation.

Motivation
The MVP is deliberately centralized (Turnkey custody, one execution backend),
which is tolerable only if the one subsystem that prices investor shares is
not: manager-attested NAV is the Stream-Finance failure class, and the
moneymentum SPEC currently has the backend posting NAV attestations to the
vault. ADR 0002 removed the manager from the marking path but left the
cross-chain-read trust model as open decision 2 — and its read rail leans on
gated infrastructure.
Solution
ADR 0003: an open attestation protocol on Solana — anyone can submit
(bonded), dispute (bonded), and verify; the backend becomes one submitter
with no special rights.
consensus reads (Wormhole Queries, trustless-verify even though
permissioned-request), TEE oracle results (Switchboard On-Demand),
zkTLS proofs, and bare bonded observations as the degraded mode.
with two-sided consumption per ADR 0002; cross-channel disagreement is a
data-integrity halt, never a pick-one.
into ADR 0002's stale-read rules.
with a concrete three-step unlock chain (the missing piece is an
Ethereum-consensus ZK verifier on Solana); CEXes stay out permanently.
for guardian-quorum verification, and a pre-specified HyperBFT
light-client ask (blocked today on the verified fact that HyperCore
state is not commitment-anchored anywhere).
Grounded in a deep-research pass (2026-06-10) with verified-primary vs
research-grade labeling inside the ADR; research-grade dependencies are
listed for re-verification before implementation.
Answers ADR 0002 open decision 2. No changes to ADRs 0001/0002 or the
program in this PR.
Closes #24
