API Reference
Lookup the application-facing runtime surface first. Drop into package overviews only when you need the owning package boundary.
If you are learning Manifesto for the first time, start with the Guide. Use this section when you know what you want to call.

Public Surface Inventory
Public Surface Inventory is generated from first-party package exports. Use it when you need to confirm whether a name is public. Use curated pages above for meaning and examples.
Package Overviews
| Package | Use When |
|---|---|
| @manifesto-ai/sdk | You want the base app runtime |
| @manifesto-ai/lineage | You need restore, branch/head history, or sealed records |

| @manifesto-ai/compiler | You need MEL compilation, lowering, or bundler adapters |
| @manifesto-ai/codegen | You need generated domain facades |
| @manifesto-ai/core | You need the pure computation layer |
| @manifesto-ai/host | You need the low-level host orchestration layer |
Tooling Overviews
| Package | Use When |
|---|---|
