# Batch 3 — Systems, Evidence, and Compatibility API Reference

This page documents the final public API Reference batch: data-adjacent system models, layout/size values, theming contracts, localization/RTL, output/evidence, verification, icon/file-system helpers, text-input state, and compatibility surfaces. It completes the type-level API reference coverage for all public type records in the current manifests.

## Batch status

| Item | Value |
|---|---:|
| Public types in batch | `53` |
| Advanced types | `45` |
| Evidence types | `7` |
| Compat types | `1` |
| V1-approved types | `0` |
| Verification | Source-documented only; no Windows/MSBuild execution was performed by this documentation pass. |

## Namespace split

| Namespace | Public type records | Primary boundary |
|---|---:|---|
| `Nexamas.UI.FileSystem` | `4` | Advanced file-picker/file-system DTOs. |
| `Nexamas.UI.Icons` | `7` | Advanced icon resolver and icon DTOs. |
| `Nexamas.UI.Layout` | `9` | Advanced layout/size values and profiles. |
| `Nexamas.UI.Localization` | `1` | Advanced RTL attachment route. |
| `Nexamas.UI.Output` | `13` | Advanced output DTOs plus evidence/readiness snapshot. |
| `Nexamas.UI.Rendering` | `1` | Evidence-oriented rendering enum. |
| `Nexamas.UI.TextInput` | `1` | Advanced text-validation enum. |
| `Nexamas.UI.Theming` | `8` | Advanced theme contracts and built-in themes. |
| `Nexamas.UI.Values` | `3` | Advanced shared typography/icon-size values. |
| `Nexamas.UI.Verification` | `5` | Evidence-oriented render-verification DTOs. |
| `Nexamas.UI.WinForms` | `1` | Compatibility surface. |

## Consumer boundary

Batch 3 contains no V1-approved beginner records. Most entries are `Advanced` contracts used through Application/window-owned routes, documented recipes, or product subsystems. Evidence records support output/readiness/render-verification proof. The single `Compat` record exists for compatibility and must not be promoted as the primary adoption route.
