Fenrua is a dual-chain AI protocol research system: Chain 978 for low-fee AI project hosting, Chain 521 for N/P-521 research, and FENiOS for evidence-aware intelligence workflows.

System object: Dual-chain protocol system model.

Primary claim: Fenrua separates support-chain execution, research-chain evidence, token-state accounting, FENiOS review, and public trust proof into distinct surfaces.

Evidence corpus: Chain IDs, live progress, FEN token-state flow, source-backed trust records.

Non-claim: Not a single-token landing page or a browser control plane.

System object: Receipt-backed FEN acquisition section.

Primary claim: FENpresale defines P-FEN as non-transferable receipt state before burn-to-claim FEN.

Evidence corpus: PFENPresale source excerpts, reserve rules, stage facts, claim schedule.

Non-claim: Not liquid FEN, reward eligibility, or the Fenrua thesis itself.

System object: Ingress method for supported source assets.

Primary claim: FENswap normalizes source assets into stablecoin-value quote language and expected P-FEN output.

Evidence corpus: Quote preview language, route boundaries, receive-state copy.

Non-claim: Not the public identity of the protocol.

System object: Post-claim reward-accounting state.

Primary claim: Reward eligibility begins only after FEN is unlocked and claimed, then staked into funded epochs.

Evidence corpus: Eligibility exclusions, funded epoch rules, no fixed APY boundary.

Non-claim: Not a presale entitlement or P-FEN staking surface.

System object: Chain 978 support-chain lane.

Primary claim: Chain 978 is the low-fee execution and evidence layer for AI project hosting, FEN settlement context, builder workflow coordination, and public protocol observability.

Evidence corpus: Chain 978 identity, live block progress, support-chain boundaries.

Non-claim: Not proof for Chain 521 cryptographic research claims.

System object: Chain 521 N/P-521 research lane.

Primary claim: Chain 521 isolates P-521 signature evidence, Groth16 shape work, N asset research, and multisig-gated release posture.

Evidence corpus: 132-byte signature evidence, vector corpus, proof cases, constraints, gas rows.

Non-claim: Not a support-chain hosting claim or unrestricted production verifier release.

System object: Evidence-aware intelligence operating layer.

Primary claim: FENiOS converts AI project intent into chain-aware requirements, evidence obligations, risk boundaries, and review-ready protocol language.

Evidence corpus: OS flow map, review interface, state-separation invariants.

Non-claim: Not a generic chatbot or privileged execution interface.

System object: Economic-continuity policy section.

Primary claim: FENdef exposes public economic observability while protecting formula and route internals that would be adversarial to publish.

Evidence corpus: FENGad, FENGas, FENSup, signed quote discipline, policy boundaries.

Non-claim: Not formula disclosure or a market-performance guarantee.

System object: Source-backed evidence corpus.

Primary claim: FENtrust renders public statements, source indexes, source snippets, report hashes, and full contract panels directly in the UI.

Evidence corpus: Trust statement, SHA references, PFENPresale snippets, audit summary.

Non-claim: Not proof of price, liquidity, yield, or future audit scope.

System object: Public signal and governance appendix.

Primary claim: FENcouncil records public voice without turning holder sentiment into execution authority.

Evidence corpus: Proposal signals, non-binding voting context, execution boundaries.

Non-claim: Not funds movement, contract mutation, validator action, or privileged control.
