# Auth Credential Semantics
This document defines the canonical credential eligibility and resolution semantics used across:
- `resolveAuthProfileOrder`
- `resolveApiKeyForProfile`
- `models status --probe`
- `doctor-auth`
The goal is to keep selection-time and runtime behavior aligned.
## Stable Reason Codes
- `ok`
- `missing_credential`
- `invalid_expires`
- `expired`
- `unresolved_ref`
## Token Credentials
Token credentials (`type: "token"`) support inline `token` and/or `tokenRef`.
### Eligibility rules
1. A token profile is ineligible when both `token` and `tokenRef` are absent.
2. `expires` is optional.
3. If `expires` is present, it must be a finite number greater than `0`.
4. If `expires` is invalid (`NaN`, `0`, negative, non-finite, or wrong type), the profile is ineligible with `invalid_expires`.
5. If `expires` is in the past, the profile is ineligible with `expired`.
6. `tokenRef` does not bypass `expires` validation.
### Resolution rules
1. Resolver semantics match eligibility semantics for `expires`.
2. For eligible profiles, token material may be resolved from inline value or `tokenRef`.
3. Unresolvable refs produce `unresolved_ref` in `models status --probe` output.
## Legacy-Compatible Messaging
For script compatibility, probe errors keep this first line unchanged:
`Auth profile credentials are missing or expired.`
Human-friendly detail and stable reason codes may be added on subsequent lines.
