Derives stable connector event IDs deterministically.

Each connector dispatch uses a stable connector_event_id derived from the source event identity and connector_type, rather than a random ID. This ensures retries and replays remain semantically tied to the same conversion event and prepares for future browser/server dedup.

Format

{connector_type}_{sha256_hex_prefix}

The hash is computed from {event_id}:{event_inserted_at_iso8601}:{connector_type}.

Collision Risk

Uses a 32-hex-character (128-bit) prefix of the SHA-256 hash. Birthday paradox collision probability reaches ~1e-18 at 10 billion events per connector type, which is well beyond expected scale. At 100M events the probability is negligible (~1e-22). If collision risk becomes a concern at extreme scale, increase @hash_prefix_length to 64 (full SHA-256).
