The signup flow now retrieves and syncs a customer’s live subscription and entitlements before rendering the home page, with webhook processing as a fallback. Free-subscription provisioning reuses existing live subscriptions. The README updates several guide statuses to “Pending Review.”

Walkthrough

The home page now checks for an active subscription and, during provisioning, runs signup billing synchronization before checking again. The sync flow processes a live subscription and syncs its entitlements. Related documentation and six README guide statuses also changed.

Changes

Signup Billing Flow

Layer / File(s)	Summary
Live subscription lookup pointer/lib/free-subscription.ts	A shared helper returns the first live subscription and customer, or null. The free-subscription flow now uses the helper to find an existing subscription.
Signup billing synchronization pointer/lib/entitlements/sync.ts, pointer/lib/signup-sync.ts, pointer/lib/signup-sync.test.ts	The signup sync resolves the billing subject, processes a found subscription through a synthetic subscription_created event, then syncs its entitlements with the signup trigger. Tests cover missing customer IDs, missing subscriptions, and lookup errors.
Home page provisioning integration pointer/app/page.tsx, pointer/ARCHITECTURE.md, pointer/app/(auth)/sign-up/page.tsx	During provisioning, the home page runs signup billing sync if its initial active-subscription query returns no subscription, then queries again. Related descriptions now refer to fetching the subscription and entitlements.

Guide Status Updates

Layer / File(s)	Summary
Guide status labels README.md	The webhook, entitlement-check, entity-sync, usage-based-billing, usage-alerts, and checkout-experience guides now show Pending Review.

Merge Risk: 🔵 Low · up to 109f4

A failed mirror write can produce a misleading signup entitlement failure event. Verify the mirror row before entitlement sync; the remaining risk is bounded by the fallback paths.

Verify the mirror row after processor.process resolves.

The processor can swallow a DB-sync hook error, so mirrorSubscription can return without creating the local subscription. syncSubscriptionEntitlements then emits chargebee.entitlements_sync_failed from assertLocalSubscription, and the outer signup handler logs and suppresses the error. The webhook and home-page polling remain recovery paths, but they do not prevent this misleading signup failure event.

After processing, verify that the mirror contains live.subscription.id and throw a retryable error if it does not. Do not rely only on processor.process to propagate hook failures.
