# HyperTwist Phase 3R Packet 3R-A KubeTimr Implementation

Created on `2026-05-13`

## Status

`Phase 3R / Packet 3R-A` is now `closed`.

This packet converts `Aarav2709/KubeTimr` from a retained permissive implementation candidate into a landed first-party HyperTwist timer subsystem lane.

It does not reopen `Phase 0R`, `Phase 1R`, or `Phase 2R-A`.

Those earlier packets still own source-value extraction, retained-set routing, and ownership boundaries.

This packet owns the next question instead:

- what first-party implementation actually landed
- which donor value was realized
- what remains explicitly out of scope for this lane
- what validation was completed
- what the next bounded implementation move is after this landing

## Authority order

For future work on the `Aarav2709/KubeTimr` lane, read in this order:

1. this packet for first-party landing scope, accepted widening, and validation result

The source read for this widening remained bounded to the retained timer/stats/splits/persistence domains:

- [LICENSE](C:/Workspaces/HyperTwist/mirrors/permissive/Aarav2709/KubeTimr/LICENSE:1)

- [src/statsEngine.ts](C:/Workspaces/HyperTwist/mirrors/permissive/Aarav2709/KubeTimr/src/statsEngine.ts:189)
- [src/splits.ts](C:/Workspaces/HyperTwist/mirrors/permissive/Aarav2709/KubeTimr/src/splits.ts:26)
- [src/persistence.ts](C:/Workspaces/HyperTwist/mirrors/permissive/Aarav2709/KubeTimr/src/persistence.ts:3)

## First-party landing surfaces

The landed first-party Unreal surfaces are:

- [HyperTwistTrainingTypes.h](C:/HyperTwist/UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingTypes.h:172)
- [HyperTwistTrainingSubsystem.h](C:/HyperTwist/UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingSubsystem.h:87)
- [HyperTwistTrainingSubsystem.cpp](C:/HyperTwist/UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingSubsystem.cpp:4998)
- [HyperTwistTrainingRepositoryLibrary.cpp](C:/HyperTwist/UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingRepositoryLibrary.cpp:5856)
- [HyperTwistCoachDashboardWidget.h](C:/HyperTwist/UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistCoachDashboardWidget.h:1244)
- [HyperTwistCoachDashboardWidget.cpp](C:/HyperTwist/UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistCoachDashboardWidget.cpp:17566)

## Landed implementation scope

What landed:

- a first-party shared live timer state machine with `Idle`, `Inspection`, `Solving`, `Paused`, and `Completed` phases
- first-party inspection penalty handling and pause/resume behavior inside the training subsystem
- first-party split capture and split undo behavior owned by the subsystem rather than the widget shell
- timer-scoped replay pause/resume event emission
- first-party widget delegation to the subsystem for start, solve-transition, pause, resume, submit, capture, and undo
- expanded rolling-window and summary stats covering `mo3`, `ao5`, `ao12`, `ao50`, `ao100`, and `ao1000`
- explicit worst and mean timing summary fields for total and raw solve time

What that means in practice:

- `Aarav2709/KubeTimr` now owns the landed permissive timer subsystem lane in HyperTwist
- the coach dashboard no longer carries the live timer as widget-local hidden state
- the timer/stats lane is now preserved as a first-party subsystem surface rather than a future donor candidate

## 2026-05-27 selective hierarchy backfill

Later timer-family source comparison does not reopen the landed product code,
but it does sharpen the ownership wording for this packet.

This packet should be read as:

- the landed `R1/F2` first-party implementation packet for the local timer
  subsystem slice
- not as a whole-family displacement of `cs0x7f/cstimer`

Preserved external hierarchy after the backfill:

- `cs0x7f/cstimer` remains the broader restrictive `A1` benchmark/oracle for
  competitive timer, stats, scramble-registry, and smart-device behavior
- `Aarav2709/KubeTimr` remains the landed permissive implementation owner for
  the narrower local timer lifecycle, split capture/editing, session stats,
  persistence, and timer-scoped replay slice
- `cubing/qqTimer` survives only as a narrow legacy session-format and embedded
  scramble-menu reference slice

## Preserved landed value

The donor value that was actually promoted is:

- keyboard-first timer lifecycle discipline
- inspection-window state and penalty semantics
- split-phase capture and ordered split editing behavior
- local/offline persistence posture
- rolling session stats and PB-oriented summary behavior

## Excluded or non-promotion boundary

Do not promote this lane into:

- the general training-platform owner
- the case-corpus or curriculum owner
- the recognition or reconstruction owner
- the hyper-runtime or topology owner
- a product-wide frontend-shell owner

Rationale:

- this repo was retained and landed because it was the selected permissive
  direct-implementation donor for the bounded local timer subsystem slice
- its value is high precisely because it is bounded
- broad trainer-shell ownership remains elsewhere in the landed and retained portfolio

## Acceptance markers satisfied

The `2R-A` acceptance markers for this row are now satisfied in first-party Unreal surfaces:

- a first-party timer state contract exists
- a first-party split contract exists
- a first-party stats contract exists
- a first-party persistence-facing timing lane exists
- a first-party timer-scoped replay contract exists

## Validation

Validation completed for this packet:

- `git diff --check` passed apart from CRLF conversion warnings
- Unreal build succeeded with:
  - `C:\Program Files\Epic Games\UE_5.7\Engine\Build\BatchFiles\Build.bat UnrealHyperTwistEditor Win64 Development C:\HyperTwist\UnrealHyperTwist\UnrealHyperTwist.uproject -WaitMutex -NoHotReloadFromIDE`

Build result:

- `Succeeded` on `2026-05-13`

## Next move

The next bounded move is `Phase 3R-B`:

- widen `Hypercubers/hypercubing.xyz` as the retained knowledge, curriculum, notation, and community lane
- keep the newly landed `KubeTimr` timer subsystem on preserve-and-enhance footing rather than treating it as an open donor candidate again
