# Stale Baseline Guard

## Purpose
Avoid acting on outdated context.

## When to Use
Use after interruptions, long sessions, branch changes, or concurrent edits.

## Inputs
Current files, branch status, latest plan, previous assumptions.

## Steps
1. Re-read the relevant current state.
2. Compare it with the last known state.
3. Identify stale assumptions.
4. Update the plan before execution.

## Gates
Baseline is current or the risk is stated.

## Evidence
Fresh file reads, status checks, or updated notes.

## Anti-Patterns
Continuing an old plan after files changed.
