# Backpropagate Specs

## Current Diff

!`git diff --stat`

## Workflow

1. Generate prompt:
   `python3 bin/loop-factory backprop --agent claude`
2. Read `factory/prompts/backprop.claude.md`.
3. Update only specs/docs made stale by actual code changes.
4. Add TODO/open question when implementation exposed missing decision.
5. Keep archived specs unchanged unless asked.

## Rules

- Preserve intent.
- Do not invent requirements.
- Keep edits minimal and evidence-linked.
