# Phase 178.2 Summary: Fresh First L1 To L2 Replay Receipt

**Status:** Done
**Date:** 2026-04-14
**Axis:** Axis 4 (human evidence) + Axis 3 (data recording)

## What was done

Phase `178.2` closed milestone `v2.4` with one durable replay packet for the
fresh-topic first L1->L2 follow-through baseline.

### Fixes landed

- the isolated fresh-topic follow-through replay is now retained under the
  phase evidence directory as a milestone-closing packet
- the replay receipt now records the exact post-registration summary,
  post-follow-through summary, staged entry count, and topic-local staged
  consultation hit count
- the milestone now has a durable proof packet for the bounded
  `register -> literature_intake_stage -> staging review` lane

## Acceptance criteria

- [x] one durable replay packet records the fresh-topic first L1->L2
      follow-through baseline
- [x] the packet captures staged-`L2` review and topic-local staged retrieval
      without widening to broader scientific claims

## Evidence

| Artifact | Location | Purpose |
|----------|----------|---------|
| `fresh-first-l1-to-l2-replay.json` | `phases/178.2-fresh-first-l1-to-l2-replay-receipt/evidence/` | durable replay packet for the fresh follow-through baseline |
| `receipt.md` | `phases/178.2-fresh-first-l1-to-l2-replay-receipt/evidence/` | human-readable summary of the milestone-closing baseline |

## What this phase proved

1. The repaired fresh-topic first L1->L2 follow-through now has one durable
   replay packet under `.planning/` rather than only ad hoc command receipts.
2. Milestone `v2.4` now closes on a mechanically replayable baseline for the
   first fresh-topic staged-`L2` follow-through.
