+    keycloak_account_events.lua
+
+This module acts as a fluent-bit event processor for raw Keycloak user events. The Accounts
+application's Celery worker periodically polls the Keycloak Admin API for recent events
+(logins, token introspections, registrations, etc.) and POSTs the raw event JSON to
+fluent-bit's HTTP input at /telemetry/keycloak.
+
+This filter handles all transformation:
+
+  - Event type mapping: Keycloak types are collapsed into PostHog event names
+    (e.g. INTROSPECT_TOKEN, REFRESH_TOKEN, CODE_TO_TOKEN → accounts.activity)
+  - Identity hashing: userId is SHA-256 hashed for use as PostHog distinct_id
+  - Field stripping: Only analytically useful fields are kept (clientId, environment, etc.)
+  - PII removal: ipAddress, details map, sessionId, and other sensitive fields are dropped
+  - PostHog formatting: Events are reformatted into the PostHog batch API payload
+
+This script needs:
+
+  - POSTHOG_API_KEY (required)
+  - ENV (optional, defaults to "dev")
