# RBAC Manager

## What this page is for

The grid view of "which agents own which tool permissions." Lists every agent, every tool in the platform catalog, and the ALLOW/DENY grant for each combination. Authors edit grants here rather than crafting POSTs to the registry by hand.

## Sidebar location & role gating

* **Sidebar group**: Settings → Access Control.
* **Path**: `/rbac`.
* **Keyboard hint**: none.
* **Minimum role for read**: `AUDITOR`.
* **Grant and revoke** require `ADMIN` or `SECURITY`.

## What you see

* **Agent search box** — filter rows by name or UUID.
* **Tool catalog selector** — the catalog of known tool names (from `/registry/tools`).
* **Grant table** — agent × tool grid. Each cell shows the action (`ALLOW` / `DENY`) plus the grantor and expiry timestamp.
* **"Grant" button per cell** — opens a small form with tool name, action, granted\_by, expires\_at.
* **"Revoke" button per cell** — confirms before deleting.
* **Per-agent permission count** — shown next to each agent name.

## Backend calls

| Action                        | HTTP   | API path                             | Service  |
| ----------------------------- | ------ | ------------------------------------ | -------- |
| List agents                   | GET    | `/agents`                            | registry |
| List tools catalog            | GET    | `/registry/tools`                    | registry |
| List permissions for an agent | GET    | `/agents/{id}/permissions`           | registry |
| Grant a permission            | POST   | `/agents/{id}/permissions`           | registry |
| Revoke a permission           | DELETE | `/agents/{id}/permissions/{perm_id}` | registry |

## Auto-refresh & realtime

* **30-second poll** via `setInterval(load, 30_000)` at `ui/src/pages/RBAC.jsx:284`.
* **No SSE.**

## Per-agent scoping

The page lists every agent in the tenant. The sidebar agent picker can deep-focus on one agent.

## Empty states

The grid renders even when an agent has zero permissions — every cell shows a Grant button. There is no platform-level empty state because the agents list is never empty for a configured tenant.

## Edge cases & known gotchas

* **409 on Grant**: a duplicate `(agent_id, tool_name)` exists. Use PATCH on the existing permission or revoke and re-grant.
* **403 on Grant or Revoke**: caller is `VIEWER` or `AUDITOR`. Re-login as `ADMIN` or `SECURITY`.
* **Permission cache 60-second lag**: a revoke takes up to 60 seconds to propagate to the gateway's permission cache. The kill switch is the fast path when seconds matter.
* **Expiry timestamps**: setting `expires_at` makes the grant automatically inactive after the moment. The row stays in the table with an "expired" badge.
* **Per-EC2 flap**: `/agents/{id}/permissions` is stable.
