# HyperTwist Phase 4 carryover review sequence-closure continuity packet

Created on `2026-05-07`

Status:

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

## Purpose

This packet lets later carry-forward plans actually retire earlier unresolved follow-up pressure in the same coach sequence.

The open tasks are:

- stop treating follow-up or deferred cases from an earlier carry-forward plan as permanently unresolved after a later resumed plan actually clears them
- stop letting sequence and closure summaries keep regenerating follow-up/queue pressure from stale historical unresolved state after the final carryover slice has already been consumed

It is not:

- a new review-plan packet
- a new queue-state packet
- a broader coach-memory redesign
- a dashboard layout rewrite

## Scope

Bounded lane:

- order coach action plans chronologically inside sequence and closure summary derivation
- track outstanding follow-up/deferred case ids as a sequence state that later focused plans can resolve
- limit generic no-case follow-up pressure to the latest relevant plan state instead of OR-ing it forever across the full sequence
- leave the existing outcome scoring and carry-forward lineage structure intact

Out of scope:

- changing coach action-plan scoring
- changing queue ordering
- rewriting follow-up brief generation
- widening into unrelated analytics or template-selection work

## Why this was the right next packet

Before this slice:

- resumed carryover review launches already restored review-plan lineage
- resumed carryover review launches already restored action-plan lineage
- resumed carryover review launches already rebound matching queue execution lineage

But one continuity seam still remained:

- sequence and closure summaries still accumulated unresolved follow-up pressure from every historical plan in the root chain
- a later carry-forward plan could finish the previously unresolved cases
- while the repository closure layer still treated those earlier unresolved case ids as live pressure

That meant:

- the resumed carryover session could close real work correctly
- while follow-up guidance, queue pressure, and closure memory could still behave as if the earlier unresolved cases had never been retired

So the next honest move was:

- resolve carry-forward sequence pressure in chronological order
- and let later plans actually clear earlier unresolved case state when they consume it

## What landed

Primary code changes:

- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingRepositoryLibrary.cpp`
  - `DeriveCoachActionSequenceSummary(...)` now sorts the root sequence chronologically
  - sequence follow-up pressure now tracks outstanding case ids across the ordered sequence so later focused plans can remove earlier unresolved pressure
  - generic no-case follow-up pressure now reflects the latest relevant plan state instead of permanently sticking once any earlier plan needed follow-up
  - `DeriveCoachActionClosureSummaryWithCoachMemory(...)` now uses the same chronological outstanding-case resolution so resolved carry-forward work can actually leave the unresolved set

## Product effect

The final carryover closure lane is now more truthful:

- later resumed carry-forward plans can now retire earlier unresolved follow-up and deferred-launch pressure in repository summaries
- follow-up guidance and queue pressure have a real path to disappear once the final carryover slice is actually completed
- closure memory can now distinguish genuinely still-open sequence pressure from already-resolved historical pressure

## Acceptance criteria

- when a later carry-forward plan resolves cases that were previously unresolved, sequence summary no longer keeps them in unresolved follow-up pressure
- closure summary can mark the sequence closed when later plans have actually retired earlier unresolved work
- generic no-case follow-up pressure does not stick forever once later sequence state no longer needs it
- full product build succeeds

## Validation checklist

1. build `UnrealHyperTwist.sln` / `UnrealHyperTwistEditor`
2. confirm coach action sequences are processed in chronological order
3. confirm later focused plans remove previously unresolved follow-up/deferred case ids from outstanding sequence pressure
4. confirm generic no-case follow-up pressure reflects latest sequence state rather than any historical occurrence
5. confirm no broader coach-memory or queue redesign was reopened

## Validation result

- full `Development Editor|Win64` build succeeded on `2026-05-07`

## Next bounded follow-on slice

- continue the same recognition-assisted coach-to-review closure validation pass at the final idle boundary: confirm that once queue-backed resumed carryover work is fully consumed and the sequence really closes, no stale follow-up, queue, or recommended actionability survives in the retained idle dashboard state
