@agecheck/core

@agecheck/core is the common TypeScript core used by AgeCheck SDK adapters.

It contains:

• token verification (verifyAgeToken)
• gate policy (isGateRequired)
• signed verification cookie helpers
• provider mode helpers for Existing Gate Integration
• typed domain errors and models

Most hostmasters should use @agecheck/node directly. Consume @agecheck/core only if you are building a framework adapter or platform integration.

Integration model support

Core primitives support all three backend integration patterns:

1. Managed Gate Mode
2. Existing Gate Integration (Provider Mode)
3. Hybrid Mode (AgeCheck + other providers)

Provider Mode helpers:

• verifyAgeCheckCredential(...)
• normalizeExternalProviderAssertion(...)
• buildSetCookieFromProviderAssertion(...)
