# Ranking

> Blocking policies first, then a character budget. No embeddings.

Ranking runs in `@stacktaste/core` on disk. No network.

## Order

1. Every injectable **policy** with `enforcement: block`.
2. Remaining injectable items until a ~3500 character budget.

Injectable = `active` or `exception`.

## Score (non-blocking)

Weighted mix of:

- Confidence (accepts, reinforcements, mentions, rejects)
- Authority (`organization` > `team` > `project` > `personal`)
- Recency (half-life about 21 days)
- Lexical match to the prompt or file paths
- Explicit items slightly above inferred ones

## Where it is used

- Cursor hook `additional_context`
- MCP `taste_context`
- Generated `.cursor/rules/stacktaste.mdc`

Do not invent extra rules beyond this slice.
