Status: Proposed · Refs: DEC-G3, DEC-G4, P-3 (unit prices pending, non-blocking)

Decision

Published unit prices; included allowances per plan; metered consumption from core.usage_snapshots (30-min deltas); projected-spend panel; tenant-configurable spend caps (self-service face of enforcement, DEC-G2). Rating engine (ours): at cycle close computes base + Σ(overage × unit price) → charge via Fintoc (enrolled card, variable amounts) or Paddle (usage-based billing) → LibreDTE invoice lines for SII. Enforcement defaults per metric: contacts grace+notice · messages hard at 110% · events soft with overage — all tenant-overridable from Softcrum Ops.

Consequences

  • Predictability as positioning; overage revenue without surprise-bill reputation damage. − Rating engine is real engineering; scoped as its own epic post-F1a.
