# HyperTwist Phase S3-B first-party recall and compact-view skills implementation packet

Created on `2026-05-29`

## Status

- first-party HyperTwist packet
- bounded `Phase S3-B` implementation slice

## Purpose

This packet lands the bounded first-party recall and compact-view skill seam
under the canonical `Skillization And Command Surface` doctrine.

The landed slice is:

- `recall-memory`
- `generate-compact-view`

It is not:

- active user-authored note capture
- workflow-memory capture widening
- opaque summary-first compacting

## 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_PHASES3_B_FIRST_PARTY_RECALL_AND_COMPACT_VIEW_SKILLS_PREPARATION_PACKET_2026-05-29.md`

## Landed scope

The current code now owns a bounded first-party recall and compact-view seam
through:

- registry promotion for:
  - `skill/recall-memory`
  - `skill/generate-compact-view`
- canonical recall/compact-view skill and aggregate state contracts in:
  - `HyperTwistSkillTypes.h`
- first-party recall/compact-view derivation over the landed registry,
  control-state, authoring-harness, `6R-M3`, and `6R-M6` seams in:
  - `UHyperTwistSkillCoreLibrary`
- sample contract helpers in:
  - `UHyperTwistContractLibrary::MakeSampleSkillRecallCompactViewState()`
  - `UHyperTwistContractLibrary::SerializeSkillRecallCompactViewStateToJson(...)`
  - `UHyperTwistContractLibrary::DeserializeSkillRecallCompactViewStateFromJson(...)`
- focused automation coverage in:
  - `HyperTwistSkillPhaseS3BRecallCompactViewContractTest.cpp`

Implemented now:

- `skill/recall-memory`
- `skill/generate-compact-view`

The compact-view skill remains intentionally bounded:

- optional only
- provenance-visible only
- linked back to authoritative sources only

## Why this is still intentionally bounded

This packet lands recall and compact-view skills only.

Still deferred:

- active user-authored note capture
- workflow-memory capture widening
- any compact view that outranks authoritative memory truth

## Validation

Build validation:

- `UnrealHyperTwistEditor Win64 Development`

Focused automation target set:

- `HyperTwist.FirstParty.Skill.PhaseS3B.RecallCompactViewCoverage`
- `HyperTwist.FirstParty.Skill.PhaseS3B.AuthoritativeCompactViewLinkage`
- `HyperTwist.FirstParty.Skill.PhaseS3B.SerializationRoundTrip`

Observed:

- the focused command-line runner discovered all `3` `Phase S3-B` automation tests
- the Unreal automation runner stalled after queue start while running
  `HyperTwist.FirstParty.Skill.PhaseS3B.AuthoritativeCompactViewLinkage` on
  this machine, so the family did not fully seal through unattended automation
  despite the green build

## Queue effect

This packet consumes the current `Phase S3-B` implementation slice.

After this landing:

- `S3-B` is landed in current code
- `S3-C` is the next clean skillization move
- active note capture still remains separately deferred
