# HyperTwist Phase S1-C first-party skill invocation, provenance, and audit ledger preparation packet

Created on `2026-05-28`

## Status

- first-party HyperTwist packet
- source-backed `Phase S1-C` preparation/control slice

## Purpose

This packet scopes the third bounded product implementation slice under the
canonical `Skillization And Command Surface` doctrine.

The granted slice is:

- invocation record format
- command/service provenance
- failure/cancel recording

It is not:

- authoring template expansion
- permissive analyzer wrappers
- restrictive clean-room command-contract specs
- wrapper execution or donor command promotion

## 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_PHASES1_A_FIRST_PARTY_SKILL_REGISTRY_AND_MANIFEST_CONTRACT_IMPLEMENTATION_PACKET_2026-05-28.md`
- `docs/arch/HYPERTWIST_PHASES1_B_FIRST_PARTY_SKILL_SETTINGS_MENU_AND_OFF_STATE_CONTROL_IMPLEMENTATION_PACKET_2026-05-28.md`

The preserved owners do not change here:

- first-party HyperTwist remains the owner of the product command surface
- the landed `Phase S1-A` registry remains the authoritative substrate
  beneath this packet
- the landed `Phase S1-B` control seam remains the authoritative off-state
  substrate beneath this packet
- optional assistive skills remain product-owned adjuncts rather than donor
  command truth

## Granted family

The bounded `Phase S1-C` slice may land:

1. first-party invocation record and outcome types
2. first-party command/service provenance state
3. first-party produced-artifact traceability state
4. first-party audit-ledger aggregate state
5. bounded sample audit-ledger derivation and JSON round-trip coverage

The packet must stay out of:

- authoring-template expansion
- analyzer wrapper execution
- restrictive clean-room command specs

## Proposed implementation shape

Land the narrower first-party boundary through:

- new skill types for:
  - invocation outcome
  - command/service provenance state
  - produced-artifact traceability
  - invocation records
  - bounded audit-ledger aggregate
- a first-party skill-core derivation function over the landed `S1-A` registry
  and `S1-B` control-state seams
- sample-contract helpers for:
  - audit-ledger derivation
  - JSON serialization
  - JSON deserialization
- focused automation in:
  - `HyperTwistSkillPhaseS1CInvocationAuditLedgerContractTest.cpp`

## Validation target

Validate with:

- Unreal build for `UnrealHyperTwistEditor Win64 Development`
- focused automation:
  - `HyperTwist.FirstParty.Skill.PhaseS1C.InvocationProvenance`
  - `HyperTwist.FirstParty.Skill.PhaseS1C.FailureCancelRecording`
  - `HyperTwist.FirstParty.Skill.PhaseS1C.SerializationRoundTrip`

## Queue effect

If this packet lands cleanly:

- `S1-C` is consumed
- `S1-D` becomes the next clean move
- do not jump straight from `S1-C` to analyzer wrappers or restrictive specs
