 Provides conflict events, fatalities, event types, and locations.

- Auth: `ACLED_EMAIL` and `ACLED_PASSWORD`.
+- Auth: `ACLED_EMAIL` or `ACLED_USER`, plus `ACLED_PASSWORD`.
 - Flow: OAuth password grant is tried first, then cookie session fallback.
- Failure modes: missing credentials, terms/profile not completed, expired token, account missing API access.
+- Failure modes: missing credentials (`no_credentials`), rejected credentials or access denied (`auth_failed`), token/API endpoint failure (`api_failed`), and valid empty event sets (`totalEvents: 0`).
 - Behavior: missing or rejected credentials produce degraded source health with the ACLED error text.
+- Debug logs redact bearer tokens and cookies.
 - Test: set credentials, run `node apis/sources/acled.mjs`, then check `/api/health`.
