# v2.4 Milestone Audit

Status: passed

## Scope Closed

- Phase `178`: Stable Literature-Stage Completion Recognition
- Phase `178.1`: Fresh First-Source Follow-Through Acceptance
- Phase `178.2`: Fresh First L1 To L2 Replay Receipt

## Requirements Coverage

Score: `5/5` requirements satisfied

- `FLC-01` satisfied by Phase `178` through stable literature-stage signatures
  persisted in staged-entry provenance.
- `FLC-02` satisfied by Phase `178` through service-side and runtime-side skip
  logic that stops requeueing an already-staged fresh-topic candidate set.
- `FLC-03` satisfied by Phase `178` through staged-`L2` review fallback
  summaries plus literature-focused context retention after the first stage
  lands.
- `FLC-04` satisfied by Phase `178.1` through one isolated fresh-topic replay
  that proves `register -> literature_intake_stage -> staged-L2 review` plus
  topic-local staged consultation hits.
- `FLC-05` satisfied by Phase `178.2` through one durable replay packet under
  `.planning/` for the same bounded baseline.

## Verification Evidence

- Phase `178` stable completion recognition:
  - `pytest-service-literature-stage.txt`: `5 passed, 151 deselected in 0.81s`
  - `pytest-runtime-stage-advance.txt`: `2 passed, 82 deselected in 0.20s`
- Phase `178.1` fresh-topic follow-through:
  - `pytest-followthrough-acceptance.txt`: `2 passed, 82 deselected in 10.58s`
  - `pytest-cli-e2e.txt`: `1 passed, 25 deselected in 4.26s`
  - `first-source-followthrough-acceptance.json`: staged entry count `1`,
    topic-local staged consultation hits `1`
- Phase `178.2` durable replay closure:
  - `fresh-first-l1-to-l2-replay.json`: post-registration summary stays on the
    literature-intake step; post-follow-through summary advances to staged-`L2`
    review

## Cross-Phase Integration

- Phase `178` first made the first fresh-topic `literature_intake_stage`
  durable so the same candidate set no longer requeues forever.
- Phase `178.1` then proved the repaired route on an isolated fresh-topic lane
  and showed that topic-local staged consultation becomes available
  immediately.
- Phase `178.2` closed the milestone with one durable replay packet so the
  bounded baseline stays replayable under `.planning/`.

## Audit Notes

- This milestone stayed narrow: it closes the first fresh-topic L1->L2
  follow-through baseline, not broader multi-lane scientific widening.
- No unsatisfied requirement remains in the `v2.4` traceability table.
- The public CLI probe after the milestone showed `next` and `consult-l2`
  already expose the staged-L2 review route and topic-local staged hits on the
  isolated baseline.

## Accepted Open Gaps

- After the first staged-L2 follow-through, public `next` can still foreground
  a control-note override path (`open_next`) instead of the staged-L2 review
  surface itself.
- The same fresh topic has not yet been proven to reenter cleanly from
  staged-L2 review into the next bounded route without extra human-control
  friction.
