Regression test - Two-node Yano devnet app chain with SCRIPT anchors (ADR 008.4 A2) and L1 observers - bootstrap the thread NFT, verify threshold co-signed anchor advances on the devnet L1, follower identity adoption, and stability-gated ~l1 deposit observations, then clean up.
Regression test - Two-node Yano devnet app chain with sequencer.mode=rotating and membership.mode=governed (ADR 008.2/008.3) - verify proposership rotates across L1-slot windows and a governed member-add activates identically on both nodes, then clean up.
Full regression of the ADR-006 app-chain extensions on a two-node devnet cluster — multi-chain (ordered-log + kv-registry), query surface, SSE, webhook sink, admin API (pause/drain/force-anchor), key rotation, evidence bundle, snapshot, metrics — then clean up.
App-chain smoke test — start a two-node Yano app-chain cluster on devnet (sequencer + member, L1 anchoring on), submit app messages, verify sequenced blocks/state roots/finality certs/MPF proofs/L1 anchor across both nodes, then clean up.
