# HyperTwist Phase S2-B first-party clean-room command-contract specs preparation packet

Created on `2026-05-29`

## Status

- first-party HyperTwist packet
- source-backed `Phase S2-B` preparation/control slice

## Purpose

This packet scopes the bounded clean-room command-contract seam under the
canonical `Skillization And Command Surface` doctrine.

The granted slice is:

- first-party command-contract specs for restrictive lanes
- bounded safety model for future clean-room skill work

It is not:

- live clean-room skill implementation
- donor command promotion
- broader training/coaching pack widening

## Current authority basis

This control pass stands on:

- `docs/ops/HYPERTWIST_SKILLIZATION_AND_COMMAND_SURFACE_DOCTRINE_2026-05-21.md`
- `docs/ops/HYPERTWIST_OPTIONAL_ASSISTIVE_FEATURE_DEACTIVATION_AND_REMOVABILITY_DOCTRINE_2026-05-21.md`
- `docs/ops/HYPERTWIST_IMPLEMENTATION_PHASE_1_KICKOFF.md`
- `docs/v6_5_deep_manual_pack/HyperTwist/ARCHITECTURE.md`
- `docs/v6_5_deep_manual_pack/HyperTwist/FEATURE_REGISTRY.md`
- `docs/v6_5_deep_manual_pack/HyperTwist/SKILLS.md`
- `docs/v6_5_deep_manual_pack/HyperTwist/PROVENANCE_AND_TRUST_MODEL.md`
- `docs/arch/HYPERTWIST_PHASES2_A_FIRST_PARTY_PERMISSIVE_ANALYZER_WRAPPERS_IMPLEMENTATION_PACKET_2026-05-28.md`

## Granted family

The bounded `Phase S2-B` slice may land:

1. first-party clean-room command-contract spec state for restrictive skill lanes
2. first-party safety rules for off-state preservation, provenance, derived-only output, and no product-truth mutation
3. registry/state-model promotion from generic clean-room pending to clean-room contract specified
4. sample contract helpers and JSON round-trip coverage

The packet must stay out of:

- live clean-room skill wrappers
- broader training/coaching domain-pack widening
- donor-derived wording or contract shapes

## Proposed implementation shape

Land the narrower first-party boundary through:

- registry promotion for the current restrictive skillization lane:
  - `skill/roux-session-review`
- first-party command/service binding update for the current restrictive skill contract
- explicit clean-room command-contract spec types and aggregate state
- first-party spec derivation over the landed registry, control, and authoring-harness seams
- sample contract helpers for:
  - command-contract-state derivation
  - JSON serialization
  - JSON deserialization
- focused automation in:
  - `HyperTwistSkillPhaseS2BCleanRoomCommandContractSpecTest.cpp`

## Validation target

Validate with:

- Unreal build for `UnrealHyperTwistEditor Win64 Development`
- focused automation:
  - `HyperTwist.FirstParty.Skill.PhaseS2B.CommandContractSpec`
  - `HyperTwist.FirstParty.Skill.PhaseS2B.SafetyModel`
  - `HyperTwist.FirstParty.Skill.PhaseS2B.SerializationRoundTrip`

## Queue effect

If this packet lands cleanly:

- `S2-B` is consumed
- `S2-C` becomes the next clean move
- live clean-room skill behavior still remains deferred behind `S2-C`
