# Known Limitations

> Implementation-derived limitations and operational boundaries.

# Known Limitations

## Deployment and scale

* Current product is single-instance/single-tenant oriented.
* Multi-node HA/cluster orchestration is not a supported GA deployment model.
* Governance Workspace performs multiple effective-state calls per Route and becomes expensive at larger Route counts.
* Streams console per-stream stats/health still scales with stream count; 50–100 Streams require operational care.

## Route Processing

Incomplete Classification/Protection override payloads can appear as **Intent only** at deploy and may require a complete save in Route Edit.

## Sources and transforms

* Database Query runtime is PostgreSQL-centric.
* Expert transform supports `regex_extract`; `regex_replace` is not part of the documented MVP.
* Unknown fields default to pass-through unless policy changes that behavior.

## Authentication

* Local JWT/RBAC is implemented.
* Enterprise SAML/OIDC/SCIM/federation is not current product scope.
* No supported account-lockout policy was proven in the audited source.

## Marketplace

Development branch contains Marketplace UI, package lifecycle, trust, remote/private registry, and offline bundle work. These are not presented as tag-proven stable release behavior.

## Data Relay Link

There is no implemented Control↔Link management protocol in the audited source.

## UI screenshots

Current screenshots were not generated during this documentation build because no live product instance was available to the documentation process. Required captures are tracked in `images/screenshots/README.md`.
