# Code Elevation — Dynamic Model

> **Version:** 1.0 | **Last Updated:** 2026-02-25  
> **Purpose:** Map the physiology of the existing codebase: how components interact at runtime for the most significant use cases. Generated by the AI collaborator during Code Elevation Stage 2. The team validates and adds hidden behaviors, workarounds, and async flows not evident in the code.  
> **Usage:** The AI populates this file during the session. The team validates before proceeding to Stage 3.

## Use Case 1: [Name]

```
[Sequence diagram using ASCII art showing component interactions]
[Include: caller, components, data stores, external services]
[Show: request flow, data transformations, response]

Notes:
- [Behavioral observation 1]
- [Behavioral observation 2]
```

---

## Use Case 2: [Name]

```
[Sequence diagram]

Notes:
- [Observations]
```

---

## Use Case 3: [Name]

```
[Sequence diagram]

Notes:
- [Observations]
```

---

> Add Use Cases 4 and 5 as needed. Cover the 3-5 most significant flows for the target Intent.

---

## Cross-Cutting Observations

> Behavioral patterns that span multiple use cases: error handling, retry logic, caching, ordering dependencies, feature flags, environment-dependent behavior.

| Pattern | Use Cases Affected | Description | Risk for New Feature Work |
|---------|-------------------|-------------|--------------------------|
| [e.g., No error handling] | [All] | [Description] | [Impact on Intent] |

---

## Data Flow Summary

> How data moves through the system across use cases. Highlight sync vs async, ordering guarantees, staleness windows, and side effects.

| Flow | Type | Source → Destination | Ordering | Notes |
|------|------|---------------------|----------|-------|
| [e.g., Task creation] | [Sync/Async] | [Client → Handler → DynamoDB] | [Guaranteed/None] | [Observations] |
