# HyperTwist Phase S7-C First-Party Creative/Media Packs Implementation Packet

Date: 2026-05-31
Status: landed

## Implemented Outputs

- `skill/compose-replay-explainer-pack`
- `skill/prepare-media-parser-pack`
- `skill/curate-shared-fixture-pack`

## Landed Product Shape

The `S7-C` layer is now live as a bounded first-party optional creative/media
adjunct family above the landed `S7-B` retained domain-pack seam. It reads
authoritative replay, timer-export, media-export, and shared-fixture source
surfaces to produce provenance-visible replay-explainer, media-parser, and
shared-fixture briefs without widening into broad runtime or authoring-shell
claims.

## 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`
  - `compose-replay-explainer-pack`
  - `prepare-media-parser-pack`
  - `curate-shared-fixture-pack`
  - `curriculum-draft-pack`
- sample audit control overrides enable the three new creative/media-pack
  skills for invocation-ledger coverage

## Contract State

New bounded state family:
- `FHyperTwistSkillCreativeMediaPackSkill`
- `FHyperTwistSkillCreativeMediaPackState`

Derived state guarantees:
- every live skill reads authoritative first-party creative/media state
- every skill requires the landed `S7-B` retained-domain-pack substrate
- creative/media adjuncts remain optional
- core runtime promotion remains out of scope
- boundary-sensitive media and shared-fixture licensing remains explicit

## 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-C` automation added for:
  - coverage
  - bounded creative/media-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`

Current named endpoint:
- the first-party bounded `S1` through `S7` skillization ladder is now landed
  through `S7-C`
