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

Created on `2026-05-28`

## Status

- first-party HyperTwist packet
- bounded `Phase S1-C` implementation slice

## Purpose

This packet lands the bounded first-party skill invocation, provenance, and
audit-ledger seam under the canonical `Skillization And Command Surface`
doctrine.

The landed 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 implementation packet 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_C_FIRST_PARTY_SKILL_INVOCATION_PROVENANCE_AND_AUDIT_LEDGER_PREPARATION_PACKET_2026-05-28.md`

The preserved owners do not change:

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

## Landed scope

The current code now owns a bounded first-party skill-audit seam through:

- canonical skill invocation-outcome, command-provenance, produced-artifact,
  invocation-record, and audit-ledger aggregate types in:
  - `HyperTwistSkillTypes.h`
- first-party audit-ledger derivation over the landed `S1-A` registry and
  `S1-B` control-state seams in:
  - `UHyperTwistSkillCoreLibrary`
- current bounded audit coverage for:
  - invocation identity and outcome recording
  - command-surface and service-binding provenance
  - owner-lane and owner-feature traceability
  - permission-scope and artifact-kind traceability
  - success, failure, and cancel recording
  - product-truth output traceability
  - no-untraceable-output guard state
- sample contract helpers in:
  - `UHyperTwistContractLibrary::MakeSampleSkillAuditLedgerState()`
  - `UHyperTwistContractLibrary::SerializeSkillAuditLedgerStateToJson(...)`
  - `UHyperTwistContractLibrary::DeserializeSkillAuditLedgerStateFromJson(...)`
- focused automation coverage in:
  - `HyperTwistSkillPhaseS1CInvocationAuditLedgerContractTest.cpp`

## Why this is still intentionally bounded

This packet lands invocation/provenance/audit-ledger storage only.

Still deferred:

- authoring/examples/validation-harness expansion
- permissive analyzer wrappers
- restrictive clean-room command-contract specs

## Validation

Build validation:

- `UnrealHyperTwistEditor Win64 Development`

Focused automation validation:

- `HyperTwist.FirstParty.Skill.PhaseS1C.InvocationProvenance`
- `HyperTwist.FirstParty.Skill.PhaseS1C.FailureCancelRecording`
- `HyperTwist.FirstParty.Skill.PhaseS1C.SerializationRoundTrip`

Observed:

- `3` focused `Phase S1-C` automation tests succeeded

## Queue effect

This packet consumes the current `Phase S1-C` implementation slice.

After this landing:

- `S1-C` is landed in current code
- `S1-D` is the next clean skillization move
- do not jump straight from `S1-C` to analyzer wrappers or restrictive command
  specs
