= infra-security

== purpose

Placeholder module reserved for security infrastructure — authentication, authorization, credential management, and secure communication. Currently contains only a `Module` marker object with no implementation.

== responsibilities

* Intended: provide authentication adapters (API keys, OAuth, etc.)
* Intended: enforce authorization checks on tool execution and API access
* Intended: manage credential storage and rotation

== non-responsibilities

* Does not define security contracts — that belongs to `core`
* Does not implement approval gates — that belongs to `core:approvals`
* Does not provide sandboxing — that belongs to `infra:tools`

== key types

=== Module
* **kind**: object
* **purpose**: Module marker for the Gradle subproject; no behavior.

== event flow

*None.* No events are consumed or emitted. This is a placeholder.

== integration points

No integration points. The module has no dependencies beyond `core:events`.

== invariants

None — module is empty.

== known issues

Module is a placeholder — no security infrastructure exists.

== open questions

* What authentication mechanism(s) will be supported (API key, JWT, mTLS)?
* Will credentials be stored in the event store or in an external secrets manager?
