# HyperTwist Phase 4 post-clear review resumption continuity packet

Created on `2026-05-06`

Status:

- first-party HyperTwist packet
- bounded Phase `4` coach-to-review validation slice

## Purpose

This packet makes a repository-backed pending review plan resumable after `ClearActiveRun()` instead of merely inspectable.

The open tasks are:

- let a rehydrated idle review plan materialize a truthful carryover review deck after the active run has been cleared
- let the owned review-run start path resume that stored review plan instead of only starting brand-new review plans from a still-active run

It is not:

- a new review-plan persistence packet
- a new queue-state packet
- a broader dashboard command-surface packet
- a rewrite of review-policy selection

## Scope

Bounded lane:

- build a carryover review deck directly from `ActiveReviewPlanState` when no run is active and the stored review plan is still open
- preserve current-entry / needs-repeat / pending ordering so review-plan mutation stays aligned with the launched deck
- let `StartRecommendedReviewRun()` resume an already-stored review plan from idle state without overwriting it with a brand-new plan

Out of scope:

- changing how review plans are scored or finalized
- changing coach queue priorities
- adding a new dedicated dashboard button surface
- widening into unrelated consumer/UI work

## Why this was the right next packet

Before this slice:

- idle review-plan rehydration after clear was landed
- post-clear coach action-plan continuity was landed
- dashboard and queue idle-closure slices were landed

But one operational seam still remained:

- after clear, the stored review plan could be rehydrated for inspection
- but `BuildActiveReviewDeck()` only worked from an active run
- and `StartRecommendedReviewRun()` only knew how to build a fresh review plan from an active run instead of resuming the stored one

That meant:

- carryover review state could survive in repository state
- while the owned runtime lane still lacked a direct way to turn that stored plan back into the next review run

So the next honest move was:

- let the stored plan materialize its own carryover deck
- and let the existing review-run start path resume that stored plan from idle state

## What landed

Primary code changes:

- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingSubsystem.cpp`
  - added a review-plan carryover deck builder that materializes live review cases from non-terminal review-plan entries
  - `BuildActiveReviewDeck()` now works from a rehydrated stored review plan when no run is active
  - `StartRecommendedReviewRun()` now resumes an already-stored review plan from idle state instead of always building a new plan from an active run

## Product effect

The post-clear review lane is now more complete:

- a stored carryover review plan can now produce the same next review deck after clear that it would have produced before clear
- the owned runtime entry point can resume that stored plan directly
- review-plan mutation during the resumed run stays aligned with the launched carryover cases instead of forcing a brand-new review-plan branch

## Acceptance criteria

- when no run is active and `ActiveReviewPlanState` is still open, `BuildActiveReviewDeck()` returns a structurally valid carryover review deck
- that deck preserves the current/repeat/pending review-plan ordering
- `StartRecommendedReviewRun()` can resume the stored review plan from idle state without overwriting it with a new plan
- full product build succeeds

## Validation checklist

1. build `UnrealHyperTwist.sln` / `UnrealHyperTwistEditor`
2. confirm `BuildActiveReviewDeck()` works with a rehydrated idle review plan
3. confirm `StartRecommendedReviewRun()` resumes the stored plan from idle state
4. confirm resumed attempts still mutate the same review plan rather than creating a new one
5. confirm no broader queue/dashboard redesign was reopened

That is the packet.
