Mirrors keysat 0014 + TS/Rust SDK 0.3.0. PublicPoliciesProduct
gains entitlements_catalog: list[EntitlementDef] with slug + name +
description. SDK consumers' in-app tier pickers can render display
names + tooltip descriptions instead of raw slugs. Empty list on
legacy products without a catalog. No breaking change.
Mirrors the TS SDK 0.2.0 + Rust SDK 0.2.0 changes for parity across
all four language clients.
StartPurchaseOptions gains `policy_slug: str | None`. New
`Client.list_public_policies(product_slug)` returns a
`PublicPoliciesResponse` carrying the buyer-visible tier list (slug,
name, price_sats, entitlements, recurring/trial flags, "Most popular"
flag). Same data the licensing service's /buy/<slug> page reads
server-side — public endpoint, no auth.
client.start_purchase("recap", StartPurchaseOptions(
policy_slug="pro",
buyer_email="buyer@example.com",
))
tiers = client.list_public_policies("recap")
for p in tiers.policies:
print(p.slug, p.name, p.price_sats, p.entitlements)
Backwards compatible — existing positional / kwarg callers continue
to work since policy_slug defaults to None.
