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

Date: 2026-05-31
Status: landed

## Implemented Outputs

- `skill/review-training-replay-pack`
- `skill/curate-curriculum-content-pack`
- `skill/prepare-media-export-pack`

## Landed Product Shape

The `S7-B` layer is now live as a bounded first-party retained domain-pack
family above the landed `S7-A` domain-pack framework seam. It reads
authoritative first-party training/replay, catalog/content, and media/export
surfaces to produce provenance-visible retained-pack briefs without widening
into optional creative/media adjuncts yet.

## Registry / Control / Audit

- registry status counts now include the three new implemented skills
- domain/creative family count now includes:
  - `specify-domain-packaging`
  - `specify-domain-pack-grouping`
  - `review-training-replay-pack`
  - `curate-curriculum-content-pack`
  - `prepare-media-export-pack`
  - `curriculum-draft-pack`
- sample audit control overrides enable the three new retained-pack skills for
  invocation-ledger coverage

## Contract State

New bounded state family:
- `FHyperTwistSkillRetainedDomainPackSkill`
- `FHyperTwistSkillRetainedDomainPackState`

Derived state guarantees:
- every live skill reads authoritative first-party domain state
- every skill requires the landed `S7-A` domain-pack framework substrate
- retained pack claims remain first-party grounded
- unlanded-pack deferral remains preserved
- creative adjunct widening remains out of scope

## Validation

- `S1-A` registry/family/status expectations updated
- `S1-B` control-state expectations updated
- `S1-C` audit-ledger expectations updated
- `S1-D` eval-contract coverage updated
- focused `Phase S7-B` automation added for:
  - coverage
  - bounded retained-pack safety
  - JSON round-trip

## Documentation Sync

Updated:
- `ROADMAP.md`
- `SKILLS.md`
- `FEATURE_REGISTRY.md`
- `HYPERTWIST_IMPLEMENTATION_PHASE_1_KICKOFF.md`
- `HYPERTWIST_SKILLIZATION_AND_COMMAND_SURFACE_DOCTRINE_2026-05-21.md`

Next clean move:
- `S7-C` creative/media packs
