# HyperTwist Phase I-A scenic virtual training environment foundations implementation packet

Date: `2026-05-31`

## Outcome

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

## What landed

The current code now owns:

- a scenic immersive environment profile contract
- a legibility-first lighting preset boundary
- a calm ambient-audio boundary
- a stable world-anchor contract for puzzle, replay, coach, and orientation
  staging
- runtime-library accessors and focused automation coverage for the new
  immersive surfaces

## Code surfaces

- `HyperTwistTrainingImmersiveEnvironmentLibrary.h/.cpp`
  - new first-party immersive foundations bundle and query surfaces
- `HyperTwistTrainingRuntimeLibrary.h/.cpp`
  - runtime accessors for the immersive foundations packet
- `HyperTwistImmersivePhaseIAEnvironmentFoundationContractTest.cpp`
  - focused automation for the immersive environment profile, lighting/audio,
    and world-anchor assertions

## Boundedness preserved

This packet does **not** claim:

- generic productivity or virtual desktop shell ownership
- floating monitor ownership
- full weather or spectacle-lighting ownership
- soundtrack or voice-playback platform ownership
- later immersive phases such as focus-presence tuning or reactive coaching
  staging

The slice remains a foundations-only first-party immersive lane.

## 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 the next deliberate
  immersive seam
- the immersive lane remains HyperTwist-native and training/runtime oriented
- the lane is still explicitly separate from any generic virtual desktop or
  forced `VectorShell` reuse posture
