Core ideas behind sessions, delegation, fees, and settle-back.
NorthStar gives you a private Solana execution environment with clear bounds. These concepts explain how that model works, what it guarantees, and where the limits are.
Sessions — the lifecycle, scope, and isolation model.
Account Delegation — how accounts become writable inside a session.
Programmable Fees — how fee budgets and fee policy stay bounded.
Settle-Back Guarantees — what commits to L1 when a session ends.
Read Sessions first. It frames the rest of the model.
Then read Account Delegation and Settle-Back Guarantees. Those two pages define the trust boundary.
