Lanework Pro is a subscription — the tier seam, StoreKit 2, and Settings

Phase 3 of the one-app pivot (DESIGN 12 ▸ The entitlement / Distribution,
ruled 2026-07-30; card c3a3ddd5). New Kanban/Tier/: Tier (.free/.pro —
deliberately no .lapsed case; unsubscribed and lapsed are one state) and
the pure decision Tier.resolve(from:now:) over SubscriptionFacts
(expiration + willAutoRenew), unit-tested through all five named states:
free, active, lapsed, offline-grace, never-online.

The facts are a persisted cache (standard defaults), not a live view:
StoreKit ages an expired subscription out of currentEntitlements locally,
so an offline device and a real lapse are indistinguishable from that
property alone — the cache holds the last answer, empty entitlements
read as silence, and holds end only on a definitive answer (revocation,
or the subscription-group status read Settings performs). That is 12's
offline-grace trade, resolved toward the paying user.

ProEntitlement is the local adapter (currentEntitlements +
Transaction.updates, started from launch, never from a test host);
ProStorefront holds everything networked (product load, purchase,
AppStore.sync) and only the Settings section ever constructs one — the
split is the enforcement of "never network on the open path".
beginSession reads the tier once at composition; BoardSession.tier is a
let with no path back in, so a lapse never rebinds an open session.
makeHistoryProvider now takes the tier; both tiers bind the native stack
until pro-m1 builds the git provider — the seam's consumer is named, not
invented early.

Settings gains the Pro section (subscribe with localized price, manage,
restore; a quiet unreachable line, no indefinite spinner) — the third of
the exactly-three Pro mentions; the About line gains its "…in Settings"
pointer now that there is a Settings to point at. A successful purchase
or restore offers once to reopen open boards (close + reopen through the
ordinary paths). Configuration.storekit wired into the scheme's run
action for ASC-free exercise; RELEASE.md gains the pro-m1 store-side
steps and the rule that the product must not be configured before then.
