[chain/appchain] Define no-value appchain prototype criteria

[FlowmemoryAI]

Objective

Define the exact entry, exit, and evidence criteria for a no-value FlowMemory Base Appchain prototype before any implementation starts.

Allowed folders

• research/appchain/
• research/l1/ only for sovereign-L1 comparison notes
• docs/ROADMAP.md only for milestone cross-links
• docs/DECISIONS/ only if a durable prototype gate decision is made

Forbidden folders

• Production chain code
• Tokenomics, validator rewards, staking, slashing, or fee markets beyond research boundaries
• Mainnet deployment scripts or deployment configuration
• Contracts outside contracts/flowmemory-chain/
• Dashboard UI
• Hardware CAD

Acceptance criteria

• Define prototype prerequisites for FlowPulse, Rootfield, work receipts, verifier reports, artifact policy, and Base anchors.
• Define no-value constraints, testnet/local-only assumptions, and explicit non-mainnet language.
• Define prototype success/failure measurements for throughput, latency, costs, reorg recovery, sequencer downtime, DA posting, and verifier reconciliation.
• Define stop conditions that prevent the prototype from becoming production work without a new approval.
• Cross-link to research/appchain/GO_NO_GO_CRITERIA.md.
