B4 — revenueCatWebhook: functions.https.onRequest → firebase-functions/v2/https onRequest,
with REVENUECAT_SIGNING_KEY bound as a Secret Manager secret via defineSecret (injected into
process.env, so the Ed25519 verify + process-before-ack/500-retry logic is unchanged). Request
type retyped to the v2 Request; console → logger. The key must be seeded in Secret Manager at
deploy (runbook) — it isn't in the repo.
B5 — onUserDelete: kept on the v1 API (2nd gen has no auth.user().onDelete), imported explicitly
from firebase-functions/v1 and wrapped in runWith({ timeoutSeconds: 300, memory: '512MB' }) for
its dual recursiveDelete + Storage sweep. Adopts shared getUserTokens/sendPushToUser + logger;
preserves the original "only notify if the partner has a live token" behavior.
(wrapReleaseKey's HttpsError→v2 swap already landed in B3.)
Build clean; 70 tests green. dist rebuilt. Still on firebase-functions v5.1.1.
