# HyperTwist Phase S7-B First-Party Retained Domain Packs Preparation Packet

Date: 2026-05-31
Owner lane: `lane/skillization/domain-creative`
Owner features:
- `feature/skills/review-training-replay-pack`
- `feature/skills/curate-curriculum-content-pack`
- `feature/skills/prepare-media-export-pack`

## Scope

Land the bounded first-party retained domain-pack layer for:
- `review-training-replay-pack`
- `curate-curriculum-content-pack`
- `prepare-media-export-pack`

This phase promotes the first retained pack families above the landed `S7-A`
framework seam without widening into optional creative/media adjunct packs yet.

## Authority Basis

- `A`: first-party training, replay, catalog, and media-export runtime and
  contract surfaces
- `R`: landed `Phase S7-A` packet plus existing first-party replay-review,
  content-pack, timer-export, and media-export bundles
- `F`: skillization doctrine `S7-B` likely-family posture

## First-Party Dependencies

- skill registry/control/audit/authoring substrate
- landed `S7-A` domain-pack framework state
- first-party training repository integrity report
- first-party deck-history, timing-trend, and personal-best summaries
- first-party replay-review analytics
- retained first-party starter content packs and catalog surfaces
- first-party timer-export packet and media-export reference bundle

## UI / Settings Exposure

- stays in `skill-group/domain-creative`
- remains optional-assistive, installed-when-disabled, and inert-when-disabled
- introduces no creative adjunct activation surface in this phase

## Audit / Provenance

- invocation-ledger required for all three skills
- produced artifacts:
  - `artifact/training-replay-review-pack-brief`
  - `artifact/curriculum-content-pack-brief`
  - `artifact/media-export-pack-brief`

## Validation Plan

- registry/family/status count update
- control-state visibility update
- audit-ledger invocation update
- authoring/eval contract coverage update
- focused `Phase S7-B` state and serialization tests

## Off-State Behavior

- skills remain visible and opt-in by default
- disabling the skills leaves retained pack grounding intact and unlanded-pack
  deferral unchanged
- no creative adjunct widening occurs in this phase

## Acceptance Gates

- retained pack claims remain grounded in first-party source surfaces
- the landed `S7-A` packaging/grouping framework remains a dependency
- unlanded-pack deferral remains explicit
- creative adjunct widening remains out of scope

## Non-Goals

- optional creative/media adjunct packs
- provider-specific overlay widening
- autonomous execution or pack mutation claims
- broad catalog proliferation beyond the first retained pack trio
