 Embeddings/passthrough are untouched by this composition step.
 
-- **Prohibited preamble content.** If the operator preamble (`gateway_system_preamble`) contains any text matching `PREAMBLE_PROHIBITED_PATTERNS` (void-world motifs: "sole consciousness", "void-world", "void world", "absolute void", "everything is allowed", "no consequences", "no rules") the entire preamble is silently discarded (with a warning log line) and the request proceeds with only the date injection and client system content. This prevents a misconfigured preamble from overriding production task instructions.

 The gateway records one row per upstream call (chat, vision, passthrough) and surfaces per-hour and 24h analytics. The pieces:
