Per the go-to-market plan in §6 — controls whether spam is blocked or only measured

Shadow modeClassify and log everything; deliver all messages — used to tune thresholds before blocking Live — quarantine enabledHigh-confidence spam (≥ 85%) is held; feedback loop and human review are active

Data & retention

Quarantine retention window 30 days

Message content storage In-memory only — SHA‑256 hash retained (FR10)

These settings require a second approver. Per §4.3, adjusting the spam threshold or the low-confidence boundary needs sign-off from the security team before it takes effect.

Quarantine confidence threshold

85%

Messages scored at or above this confidence are quarantined. Raising it reduces false positives but lets more borderline spam through.

70% (more aggressive)98% (more conservative)

Open question from §11: organizations handling critical SMS (healthcare alerts, banking OTPs) may want a threshold ≥ 90% to minimize false positives in high-stakes flows.

Low-confidence review boundary

Messages inside this band are routed to the analyst review queue instead of being auto-decided (Flow 5)

to currently 0.31% of traffic falls in this band

Trusted senders

Allowlisted senders bypass spam scoring entirely — additions require admin approval (§4.3)
