# v2.2 Preamble Manifests

> PROFILE, AUDIENCE, ONTOLOGY, BUNDLE — four first-contact manifests.

v2.2 adds four optional manifests before normal packets. They are ordinary OBS packets over reserved `@m.*` subjects. The packet grammar does not change.

Order: PROFILE => AUDIENCE => ONTOLOGY => BUNDLE.

## PROFILE

Declare tokenizer, charset, density, and capabilities.

```
ID:SYS|OBS.99|@m.PROFILE|@agent.SYS|^v:2.2+^charset:ascii+^tok:neutral+^density:mid+^cap:onto+^cap:bundle|NOW
```

| Key        | Required | Values                                                              |
| ---------- | -------- | ------------------------------------------------------------------- |
| `^v`       | Yes      | `2.2`                                                               |
| `^charset` | Yes      | `legacy` or `ascii`                                                 |
| `^tok`     | Yes      | `cl100k`, `anthropic`, `sp_llama`, `sp_gemini`, `tekken`, `neutral` |
| `^density` | Yes      | `low`, `mid`, `high`                                                |
| `^cap`     | No       | Repeatable: `onto`, `bundle`, `decomp`                              |

## AUDIENCE

Declare intended receiver.

```
ID:FIN-01|OBS.99|@m.AUDIENCE|@agent.FIN-01|^to:role.trader+^to:cap.flow_parse|NOW
```

## ONTOLOGY

Declare aliases before use.

```
ID:ASM-01|OBS.99|@m.ONTOLOGY.swarm|@agent.ASM-01|^def:PLT=platoon+^def:COH=cohort+^map:PLT=tactical+^map:COH=fusion|NOW
```

After this, `PLT` and `COH` are valid in subsequent packets.

## BUNDLE

Declare claim graph for structured doctrine.

```
ID:ARCH-01|OBS.99|@m.BUNDLE.B1|@agent.ARCH-01|^root:C2+^mode:strict+^order:topo+^claim:C1+^claim:C2+^dep:C2>C1|NOW
```

| Key      | Required | Description                                    |
| -------- | -------- | ---------------------------------------------- |
| `^root`  | Yes      | Root claim                                     |
| `^mode`  | Yes      | `strict` (1:1) or `loose` (may fuse)           |
| `^order` | Yes      | `topo` (dependency) or `time` (timestamp)      |
| `^claim` | Yes      | Repeatable claim IDs                           |
| `^dep`   | No       | `child>parent`                                 |
| `^c`     | No       | Confidence vector: `^c:C1.obs=95+^c:C1.map=94` |

## Backward Compatibility

v2.1 agents parse manifests as ordinary OBS packets about `@m.*` entities. Unknown keys ignored. Normal packets unaffected.
