# HyperTwist Phase 4 queue brief continuity packet

Created on `2026-05-06`

Status:

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

## Purpose

This packet closes the next end-to-end continuity gap in the live recognition-assisted coach-to-review loop.

The open task is:

- preserve full queue-backed coach-brief semantics when coach guidance is materialized into queue entries and later reconstructed back into action-plan starts

It is not:

- a new recognition transport packet
- a new review-policy heuristic packet
- a new dashboard packet
- a broad queue-system rewrite

## Scope

Bounded lane:

- persist the coach-brief fields that materially shape downstream coach action plans through queue summary and queue state
- reconstruct queue-backed coach briefs from those persisted fields instead of inferring them from delivery mode or source label alone
- keep queue fingerprints aligned with the widened preserved semantics so queue-state continuity remains honest

Specifically preserved through the queue lane:

- source brief training session id
- source review-plan id
- carry-forward/root plan lineage and follow-up depth
- focus lane and primary action label
- deferred-launch recovery state
- coach-review, cadence-recovery, and variety-rotation flags
- recognition-review preference

Out of scope:

- new queue prioritization rules
- new coach-signal derivation
- new replay scoring
- new UI layout work

## Why this was the right next packet

Before this slice:

- recognition replay pressure already flowed into coach guidance
- queue entries already preserved recognition-review preference explicitly
- review-policy continuity and review-policy inspection were already landed
- recognition-biased repeat pressure already escalated correctly into coach intervention

But the queue reconstruction lane still dropped critical coach-brief semantics:

- coach-review intent could collapse to `false` unless suggested mode was explicit `CoachReviewed`
- queued follow-up entries lost carry-forward lineage
- queue-started action plans could lose source review-plan linkage, focus lane, primary action label, and cadence/variety/deferred-launch state

That meant the broad Phase `4` validation lane was still not end-to-end coherent once guidance crossed the queue materialization boundary.

So the next honest move was:

- preserve queue-backed coach brief continuity directly rather than layering more downstream fixes on top of lossy queue reconstruction

## What landed

Primary code changes:

- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingCoachLibrary.h`
  - widened queue-summary entry structure to carry the coach-brief state needed for downstream continuity
- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingTypes.h`
  - widened queue-state entry structure to persist the same continuity fields through repository state
- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingCoachLibrary.cpp`
  - queue summary creation now copies the relevant coach-brief semantics into queue entries
- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingRepositoryLibrary.cpp`
  - queue-state construction now preserves those fields and queue fingerprints now include them
- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingSubsystem.cpp`
  - queue-backed brief reconstruction now restores coach-review intent, review-plan linkage, follow-up lineage, focus lane, action label, deferred-launch state, cadence/variety flags, and recognition-review preference from queue state

## Product effect

Queue-backed coach execution is now materially more coherent:

- recognition-assisted queue entries no longer lose coach-review intent just because they run in `RecognitionAssisted` mode
- queued follow-up guidance now preserves carry-forward/root-plan lineage into action-plan starts
- queue-started action plans now retain the same focus lane and primary action label that shaped the original brief
- deferred-launch, cadence, and variety state now survive the queue materialization boundary instead of resetting during reconstruction
- dashboard queue-preview and action-plan inspection now stay closer to the original coach guidance because they read the reconstructed brief path

## Acceptance criteria

- queue-backed brief reconstruction no longer infers coach-review intent from delivery mode alone
- queue entries preserve follow-up lineage and review-plan linkage needed by downstream action-plan creation
- queue-started action plans retain primary action label, focus lane, deferred-launch state, cadence/variety flags, and recognition-review preference
- queue fingerprinting reflects the widened preserved semantics
- full product build succeeds

## Validation checklist

1. build `UnrealHyperTwist.sln` / `UnrealHyperTwistEditor`
2. confirm queue summary entries preserve the coach-brief fields that materially affect action-plan creation
3. confirm queue-state construction and fingerprinting preserve those widened semantics
4. confirm queue-backed brief reconstruction restores coach-review intent, follow-up lineage, and review-plan linkage without reopening a broader packet
5. confirm dashboard/preview surfaces continue reading the reconstructed queue-backed brief path without compile or runtime-surface regressions

That is the packet.
