# Model Index

## 1. Purpose

This file is the main index of the CCPE model library.

It records all known cognitive models, candidate models, extracted models, deprecated models, and model assets used by Agents, Skills, and Runtimes.

The Model Index is the map.  
The Model Card is the full model record.

## 2. Status Legend

Use these status values:

```text
candidate
draft
active
rejected
merged
deprecated
archived
```

### candidate

A possible model has been identified but still needs review.

### draft

The model structure is clear enough to document, but not yet confirmed as canonical.

### active

The user has confirmed the model as part of the active model library.

### rejected

The candidate was reviewed and rejected as a model.

### merged

The model was merged into another model.

### deprecated

The model is preserved historically but no longer recommended.

### archived

The model is inactive and kept only for historical reference.

## 3. Review Status Legend

Use these review status values:

```text
needs-source-check
needs-user-confirmation
needs-scope-review
needs-falsification-boundary
needs-merge-review
reviewed
```

## 4. Model Type Legend

Use one or more:

```text
foundational
intermediate
applied
workflow-model
implicit-extracted
candidate
deprecated
```

## 5. Layer Legend

Use one or more:

```text
L0: Foundational Assumption
L1: Foundational Model
L2: Intermediate Model
L3: Applied Model
L4: Workflow / Procedure Model
L5: Output / Evaluation Lens
```

## 7. Candidate Models

Use this section for models identified but not yet ready for full Model Cards.

| Candidate ID | Provisional Name | Source | Confidence | Reason for Candidate Status | Next Action |
| ------------ | ---------------- | ------ | ---------- | --------------------------- | ----------- |
| TBD          | TBD              | TBD    | TBD        | TBD                         | TBD         |

## 8. Active Models

Move confirmed active models here after user approval.

## 10. Maintenance Rules

When adding a model:

```text
1. Assign a stable model_id.
2. Add model name and aliases.
3. Mark type and layer.
4. Set status.
5. Link canonical path if Model Card exists.
6. Record source.
7. Record related agents and skills if known.
8. Add review status.
9. Update dependency map if relationships are known.
10. Update usage map if used by Agents, Skills, or Runtimes.
```

## 11. Promotion Rules

Candidate → Draft when:

```text
Model structure is clear.
Source is identified.
Scope and mechanism are present.
```

Draft → Active when:

```text
User confirms model name.
User confirms scope.
Model Card exists.
Falsification boundary exists.
Usage map is updated.
```

Active → Deprecated when:

```text
User rejects it.
It is superseded.
It merges into another model.
It no longer represents current thinking.
```

## 12. Notes

The initial entries are placeholders based on known user model names.

They should be reviewed through Model Mining Mode before being promoted to active status.
