The data-server-driven goal: a compiled AILang kernel callable in-process from a concurrent Rust host so a backtest swarm runs each backtest as an independent single-threaded computation. Decomposed into five chronologically-bounded milestones (M1 linkable artifact+scalar entrypoint, M2 per-thread ctx+concurrency safety, M3 frozen value layout+ADT crossing, M4 List-ADT sequence crossing, M5 ail-embed adapter+swarm fieldtest), each its own full brainstorm->plan->implement->audit cycle. Shared motivation + three audited invariants (clean core / single-threaded per computation / native-AOT-only) carried on the M1 entry. The flat array/slice primitive is recorded P2 as a measured performance follow-up gated on M5's fieldtest, not a capability gap — keeping the ABI arc's scope clean. Decision made in the 2026-05-18 data-server analysis chat; no spec yet (brainstorm produces M1's spec at start).
