# HyperTwist Phase S5-A Implementation Packet

Date: `2026-05-31`

Packet: `Phase S5-A`

Title: `first-party workflow/review wrappers`

## Outcome

Implemented now.

## Landed scope

- live `skill/review-proposal`
- live `skill/review-diff`
- live `skill/wrap-bounded-workflow`
- bounded first-party workflow/review state over authoritative extraction,
  workflow-memory, design-shell, and packet source surfaces
- registry, control-state, audit-ledger, authoring-harness, sample-contract,
  and JSON round-trip support

## Preserved boundaries

- workflow/review wrappers remain provenance-visible and bounded
- extraction, workflow-memory, and design-shell remain separate prerequisite
  seams
- no `S5-B` implementation-review or delegation widening in this packet
- no `S5-C` plan synthesis or orchestration widening in this packet

## Validation

- build target: `UnrealHyperTwistEditor Win64 Development`
- focused `S5-A` automation passed for workflow/review coverage, bounded
  workflow/review behavior, and serialization round-trip
- `S4-C` regression passed after the new family landed
- full `Phase S1` skill substrate regression passed after the new family
  landed
