# HyperTwist Phase I-C spatial coaching and tutorial staging implementation packet

Date: `2026-05-31`

## Outcome

`Phase I-C` is now landed locally as the third bounded HyperTwist-native
immersive packet.

## What landed

The current code now owns:

- a coach-cue anchor contract
- a ghost-target boundary
- a replay-emphasis boundary
- a lesson-state spotlighting contract
- runtime-library accessors and focused automation coverage for the new
  immersive teaching/staging surfaces

## Code surfaces

- `HyperTwistTrainingImmersiveEnvironmentLibrary.h/.cpp`
  - new first-party coaching and tutorial staging surfaces inside the existing
    immersive environment bundle
- `HyperTwistTrainingRuntimeLibrary.h/.cpp`
  - runtime accessors for the `Phase I-C` immersive staging packet
- `HyperTwistImmersivePhaseICCoachingStagingContractTest.cpp`
  - focused automation for coach-cue, ghost-target, replay-emphasis, and
    lesson-state assertions

## Boundedness preserved

This packet does **not** claim:

- generic cutscene ownership
- broad cinematic timeline ownership
- cross-product tutorial engine ownership
- generic mission scripting ownership
- later immersive phases such as reactive session-state environment cues

The slice remains a training-native teaching/staging follow-on above `Phase I-A`
and `Phase I-B`.

## Canon impact

The HyperTwist canon now records:

- `Phase I-A` scenic virtual training environment foundations is landed
- `Phase I-B` immersion and focus-presence controls is landed
- `Phase I-C` spatial coaching and tutorial staging is landed
- `Phase I-D` reactive session-state environment cues is the next deliberate
  immersive seam
- the immersive lane remains HyperTwist-native and training/runtime oriented
- the lane still does not become a generic virtual desktop shell, cutscene
  system, or cross-product tutorial-engine takeover
