 /**
- * Plugin telemetry helpers — shared field builders for plugin lifecycle events.
+ * Legacy plugin metadata helpers shared by call sites that still assemble
+ * analytics-compatible payload shapes.
  *
- * Implements the twin-column privacy pattern: every user-defined-name field
- * emits both a raw value (routed to PII-tagged _PROTO_* BQ columns) and a
- * redacted twin (real name iff marketplace ∈ allowlist, else 'third-party').
- *
- * plugin_id_hash provides an opaque per-plugin aggregation key with no privacy
- * dependency — sha256(name@marketplace + FIXED_SALT) truncated to 16 chars.
- * This answers distinct-count and per-plugin-trend questions that the
- * redacted column can't, without exposing user-defined names.
+ * In this fork the downstream analytics sinks are disabled, so these helpers
+ * only normalize/redact fields for local compatibility code; they do not
+ * imply an active telemetry export path.
