Subject: [PATCH] bascule-gateway: BASCULE_DEMO_AUDIT=1 startup synthesizer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds an env-gated startup hook that submits one synthetic AuditEvent
(notarize=true) to the AuditPipeline. The flush_loop then submits the
leaf to QM via CreateAnchor on its next cycle, demonstrating the
bascule→QM integration end-to-end without requiring real OIDC sessions
(genesis hasn't lifted the realm yet).

Default off — only triggers if BASCULE_DEMO_AUDIT=1 in pod env. Leaves
no permanent test surface in normal deployments. Slated for removal
once OIDC sessions can drive the path through the auth filter chain;
keeping it default-off makes that removal a no-op for production.
