# Constants

`Constants` is a static holder class that centralizes fixed literal values used across the policy domain: the SAIF service-center contact identifiers used for routing correspondence/notifications, the earliest allowable submission-entry date, and the string flag values that represent boolean true/false in database-backed fields.

## Purpose
- Provide a single source of truth for the service center's email address and mail identifier so callers do not hard-code these values.
- Define the minimum valid submission entry date (`1/1/1900`) used as a floor/sentinel value in date validation.*
- Define the canonical string representations (`"Y"`/`"N"`) used for flag-style fields persisted as strings rather than native booleans.

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

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| `SERVICE_CENTER_EMAIL_ADDRESS` | `Public Const SERVICE_CENTER_EMAIL_ADDRESS As String = "servicecenter@saif.com"` | The email address used to route correspondence to the SAIF service center.* |
| `SERVICE_CENTER_MAIL_ID` | `Public Const SERVICE_CENTER_MAIL_ID As String = "SERVIC"` | The internal mail/routing identifier for the SAIF service center.* |
| `MininumSubmissionEntryDate` | `Public Const MininumSubmissionEntryDate As Date = #1/1/1900#` | The earliest date considered valid for a submission entry; used as a floor value when validating or defaulting submission dates.* |
| `TRUE_FLAG` | `Public Const TRUE_FLAG As String = "Y"` | The string value that represents a boolean "true" in flag-style fields persisted as `Y`/`N` characters. |
| `FALSE_FLAG` | `Public Const FALSE_FLAG As String = "N"` | The string value that represents a boolean "false" in flag-style fields persisted as `Y`/`N` characters. |


## Behavioral notes
- Source declaration: `Business\SAIF.Business.Policy\Constants.vb`.
- Related operations, rules, and SQL are cross-referenced from the library-level documentation.

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