Access policies — Tollstile

Policies run in order for each request. The first decision that is not skip wins.

Decision	Meaning	Built-in
`grant`	Let the caller through with no charge	`subscriber({ active })`
`reserve`	Pay from a balance: reserve, then commit or release	`credits({ balance })`
`pay`	Require a payment on a rail	`payPerCall()`
`skip`	Let the next policy decide	—

toll.price("$0.01", {
  access: [subscriber({ active }), credits({ balance }), payPerCall()],
});

Omit access to require payment from everyone.
If access is set and nothing grants, reserves, or asks for payment, the request is denied with 403.
Policies receive the normalized context — the Web Request, the authenticated principal, and MCP details — never a framework object.

Tollstile evaluates the pricing and access policy you define; it does not decide what your service should cost.
