# Severity Fusion Prep — PREP-POLICY-ENGINE-40-001-SEVERITY-FUSION-DEP
|
|
|
|
Status: Draft (2025-11-20)
|
|
Owners: Policy Guild · Concelier Guild
|
|
Scope: Capture severity fusion requirements using violation events (38-201).
|
|
|
|
## Dependencies
|
|
- Violation event schema (38-201).
|
|
- Concelier severity sources + lattice rules; Policy weighting outputs (30-101).
|
|
|
|
## Draft fusion rules
|
|
- Inputs: violation events with status + severity + advisory/confidence.
|
|
- Rules: deterministic lattice; combine source severities with weights from 30-101; tie-break via Concelier source ranking; emit `severity_fused`, `reason_codes[]`, `sources[]` with weights.
|
|
- Determinism: sort sources lexicographically; fixed numeric precision (scale 3).
|
|
|
|
## Acceptance
|
|
- Schema draft at `docs/modules/policy/schemas/severity-fusion@draft.json` and sample at `docs/modules/policy/samples/severity-fusion@draft.json`.
|
|
- Document weight caps and rounding rules.
|
|
|
|
## Handoff
|
|
Prep artefact for PREP-POLICY-ENGINE-40-001-SEVERITY-FUSION-DEP. Finalize once violation events and Concelier severity ranking are frozen.
