# Phase 178.1 Context: Fresh First-Source Follow-Through Acceptance

## Why this phase exists

Phase `178` repaired the local route logic, but the milestone still needed one
fresh-topic proof that the real first-use lane can:

- register its first source
- execute exactly one bounded `literature_intake_stage`
- advance onto staged-`L2` review
- expose a topic-local staged consultation hit

## Bounded goal

Add one isolated acceptance script that replays that exact lane and emits a
durable JSON packet for later milestone closure.
