## Description

Sidecar record caching a conversation's compiled system prompt. Shares the rkey (TID) of its conversation; different collection (the atproto sidecar pattern). Conversations are stable records, so future strongRefs to them keep working while this record mutates.

## Definitions

### `xyz.quasigod.lab.letta.compiledPrompt`

**Type**: `record`

Compiled system prompt for one conversation, stored at the conversation's rkey. Recompile overwrites in place (same rkey, new cid): at most one record per conversation, stable identity.

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `agent` | `string` (at-uri) | Yes | The agent whose system template was compiled. |
| `content` | `string` | Yes | Full compiled system prompt: the agent's template with core memory injected. |
| `compiledAt` | `string` (datetime) | Yes |  |
| `coreMemory` | `string` | Yes | The rendered core-memory portion only. Kept separate from content because it is re-injected mid-conversation as a memory update when memfs changes; it is a substring of content. |
| `conversation` | `string` (at-uri) | Yes | The conversation this prompt belongs to. Matches the record key; kept explicit so the graph is traversable from the conversation. |
| `memfsRevision` | `string` | No | Memfs git revision the core memory was rendered from. Used to detect staleness when memory files change. |
| `rawSystemHash` | `string` | Yes | Hash of the raw system template. Used to detect staleness when the agent's template changes. |
