Every node fires through DEMAS.
Six gates, every block, fail-closed. The lines marked demas are the JIT audit layer intercepting at every node boundary.
The autonomous pipeline
that scales organic traffic.

Unit Economics
$0.0006 per page. Here’s the math.
The Writer node (Node 5, the only sustained inference path) runs on a self-hosted Gemma 4 26B-A4B MoE on a single A100 80GB. Fixed monthly VM cost ÷ pages served. Below: cost derivation, then the volume that produces it.
$5.06/hr × 730 hrs/mo = ~$3,694/month (a2-ultragpu-1g · 1× A100 80GB)
~$3,694/month ÷ ~6.16M PDPs/month = ~$0.0006/PDP
~$3,694/month ÷ ~6.16M PDPs/month = ~$0.0006/PDP
11 tenants × ~45K products × ~21 locations = ~10.5M PDPs per full run
~10.5M PDPs × 7 DAG nodes = ~73.5M ops per full run
~10.5M PDPs × 7 DAG nodes = ~73.5M ops per full run

Reading the trace.

Beat 2 of 5
Node 5 is the only inference call.
~11 seconds of generation, ~1 millisecond of validation. The probabilistic surface is small and pinned at one node — every other node is deterministic.
Beat 3 of 5
Failures don’t propagate.
The line marked FAIL halts downstream. Firestore captures the trace; the orchestrator retries with a corrected prompt. Nothing below threshold reaches production.
Beat 4 of 5
~73.5M of these lines per cycle.
Eleven tenants, seven nodes, ~10.5M product-location pages — a full run writes about 73.5M telemetry events to Langfuse. The pipeline is silent everywhere else.

Geography & Deployment
5 countries. 234 surfaces.
Node 1 (City DNA) injects language, regulation, and timezone before any downstream node fires. City data is cached and reused across all products in that geography.
