# HyperTwist Phase 4 runtime-library coach queue-recovery and handoff-continuation surface packet

- bounded Phase `4` runtime-consumer slice
- date: `2026-05-09`

## Intent

Stay on the deliberate `UHyperTwistTrainingRuntimeLibrary` world-context consumer lane and expose the next truthful coach display contracts above the already-landed active primary CTA and queue-control helpers.

## Why this packet exists

The previous runtime-library packet removed the provenance and queue-target glue around the common displayed coach action path. World-context callers could launch or mutate the common displayed coach actions, and they could read the active primary CTA and queue-control surfaces directly.

But they still had to inspect raw schedule-policy, queue-execution, suppression, and handoff state if they needed to explain:

- why continue, defer, or promote is preferred
- whether the active continuation posture is queued, follow-up, or recommended

That kept the runtime-library caller seam behind the already-landed panel-widget and session-actor display-contract lane.

## What changed

- added `GetActiveTrainingCoachQueueRecoveryPostureSurface()`
- added `GetActiveTrainingCoachHandoffContinuationSurface()`
- derived both surfaces from the same active coach panel state, schedule-policy summary, queue-execution summary, primary CTA surface, and queue-control surface already used by the panel-widget and session-actor helpers
- kept the runtime-library lane purely compositional over already-cached active coach state without reopening backend derivation

- `C:\HyperTwist\docs\HYPERTWIST_ROADMAP_OVERHAUL_EXPANSION_GUIDE.md`

## Outcome

World-context gameplay and Blueprint callers can now ask the runtime library for:

- the truthful queue-recovery posture over the active coach CTA and queue-control state
- the truthful queued-vs-follow-up-vs-recommended continuation posture over that same state

without reading raw schedule-policy summaries, queue-execution counters, suppression strings, or handoff enums directly.

## Validation

- full `Development Editor | Win64` MSBuild on `UnrealHyperTwist.sln`

## Next clean slice

Stay on this runtime-library consumer lane only if a real world-context caller still needs one more thin derived coach/generated-mode display contract or displayed-action convenience helper over already-cached state. The next best bounded move inside that lane would be the runtime-library focus/provenance and workload/budget surfaces, because those are the next truthful contracts above the newly-landed queue-recovery and handoff-continuation surfaces.
