"""Layer 4 — closed-loop full-link: business system -> gate -> data -> Console.

One run proves both halves of the §D.1 promise on the live stack:
  * SEED truth — the deterministic 15-scenario _audit_log drives the Console read
    endpoints (posture / traffic / events / audit), asserted against the manifest.
  * EGRESS truth — real client relays (clean, PHI-desensitize, injection-deny,
    embeddings) traverse nginx -> §D.1 gate -> MCP spine -> mock upstream, and the
    raw identifier never reaches the upstream.

Console assertions run BEFORE the relays so they read the clean seeded state
regardless of whether a relay also writes _audit_log. Both green = closed loop.

Skip-gated on MEDHARNESS_LIVE_BASE + a running stack.
