Reference Architectures / Marketplace Trust

Staging analyzers so a conversation can carry three risks at once.

A marketplace conversation can be abusive, fraudulent, and a credential lure simultaneously. This architecture runs a cheap primary screen, then fires specialized analyzers conditionally - each risk routed to the workflow that owns it.

Illustrative reference architecture. The scenario, volumes, and economics below are modeled - not a named customer case study. Validate every number against your own workload.

The scenario

A mid-size marketplace processes buyer–seller messaging plus public listings. A single flat classifier cannot tell "this message is rude" from "this message is a payment-diversion scam." The trust team needs each risk type routed differently: moderation for abuse, a transaction hold for fraud, and a security workflow for credential lures.

Before / after architecture

Before

listing / message | v SINGLE CLASSIFIER (one "risk" score) | v allow | flag | one queue for everything

With Sentiqra

listing / message | v PRIMARY SCREENING Trust & Safety + Fraud | v SIGNAL ROUTER | +----------+----------+-----------+ | | | | v v v v abuse fraud credential clean signals signals lure? | | | | v v v v publish moderation hold Cybersecurity policy txn + review | | v +--> security workflow

Decision ownership stays with you

Illustrative economics

Both columns are modeled from explicit assumptions. Do not treat these as guaranteed savings - model them against your own workload.

Current approach (modeled)

  • N messages × flat classifier cost
  • + manual split of flagged items into abuse / fraud / security buckets
  • + wrong-queue cost: fraud treated as rudeness, lures as spam

With Sentiqra (modeled)

  • N messages × primary screen (2 analyzers)
  • + N × conditional rate × deeper analyzers
  • = cheaper than N × all analyzers, with per-domain routing included

Example: 8M messages at 1.15 average analyzers ≈ 9.2M runs vs 32M with unconditional pipelines. At Production tier ($799/mo incl. 500K runs, $1.50/1K overage): 9.2M ≈ $13,849/mo (~$166K/yr) vs 32M ≈ $48,049/mo - a 3.5× cost difference from routing alone. Model your real conditional rate. See current pricing.

Failure behavior

Enterprise architects care about what happens when analysis is unavailable almost as much as accuracy. Define these states explicitly.

Sentiqra available

Normal staged flow - primary screen, conditional escalation, domain-owned routing.

One analyzer fails

Partial evidence - other domain signals still route; failed branch retries or holds for review.

Sentiqra unavailable

Customer fallback policy decides: allow, queue, or hold. Defined in your runbook, not improvised.

Quota / spend cap reached

Explicit state. Primary screen can keep running while conditional branches degrade gracefully.

Transaction-hold backlog

Holds age out per your policy - the signals that triggered them remain stored and replayable.

Illustrative operational impact

Three risks stay visible

Abuse, fraud, and lures in the same conversation each produce their own signal set - nothing collapses into one score.

Domain ownership

Moderation sees abuse signals, fraud ops sees transaction-risk signals, security sees lures. Each team gets its own queue.

Staged economics

The cheap primary screen runs on everything. Deeper analysis fires only when the primary screen warrants it.

What to measure in your evaluation

Run both approaches against the same labeled production sample. Compare:

Conditional firing rate (analyzers per message)
Per-domain queue accuracy
Fraud catch rate vs. flat classifier baseline
p95 latency on the primary screen path
Cost per 1,000 messages under real traffic
Hold-release accuracy on transactions

The right migration decision should come from your workload - not a generic savings percentage.
