# PolicyIssuanceSystems

`PolicyIssuanceSystems` is a nested enumeration of `Enums` that classifies which system (PMS, WCIS, or WINS) issued a policy. `Enums.ConvertPolicyIssuanceSystem` translates between this enum and its persisted database codes.

## Purpose
- Represent the fixed, closed set of policy-issuance-system codes recognized by the policy domain, per [BR-POL-003](../../../../business-rules.md#br-pol-003-persisted-policy-codes-map-to-fixed-domain-enums).
- Provide the `Unknown` fallback value used when a persisted policy-issuance-system code cannot be mapped, per [BR-POL-004](../../../../business-rules.md#br-pol-004-unrecognized-codes-translate-to-safe-defaults).

## Context
- Namespace: `SAIF.Business.Policy`
- Assembly/package: `SAIF.Business.Policy`

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| `Unknown` | `Unknown = 0` | Default/fallback value used when the persisted code does not map to a recognized issuance system. |
| `WCIS` | `WCIS` | Represents the `"WCIS"` policy-issuance-system code. |
| `PMS` | `PMS` | Represents the `"PMS"` policy-issuance-system code. |
| `WINS` | `WINS` | Represents the `"WINS"` policy-issuance-system code. |

## Constraints and usage notes
- Consumers should rely on the declared public surface rather than internal implementation details.

> **Note:** Statements marked with * were inferred from code structure, naming conventions, or
> contextual evidence where direct confirmation was not available in source artifacts. Statements
> marked with ** could not be confirmed; treat as unknown until verified.
