+# HyperTwist Phase 6R-M6 first-party derived memory and optional adjunct implementation packet
+
+Created on `2026-05-28`
+
+## Status
+
+- first-party HyperTwist packet
+- bounded `Phase 6R-M6` implementation slice
+
+## Purpose
+
+This packet lands the bounded first-party derived-memory and optional-adjunct
+seam under the canonical `Memory Lanes` doctrine.
+
+The landed slice is:
+
+- compact summaries
+- reduced context packets
+- optional digest views
+
+It is not:
+
+- a broad memory federation packet
+- a replay of `6R-M1`, `6R-M2`, `6R-M3`, `6R-M4`, or `6R-M5`
+- active user-authored note capture
+- any derived layer that can become the only stored representation
+
+## Current authority basis
+
+This implementation packet stands on:
+
+- `docs/ops/HYPERTWIST_MEMORY_LANE_AUTHORITY_AND_PHASE_IMPLEMENTATION_DOCTRINE_2026-05-21.md`
+- `docs/ops/HYPERTWIST_CONTINUITY_LATTICE_AND_CONTEXT_ASSEMBLY_PROFILE_DOCTRINE_2026-05-23.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/PROVENANCE_AND_TRUST_MODEL.md`
+- `docs/arch/HYPERTWIST_PHASE6R_M6_FIRST_PARTY_DERIVED_MEMORY_AND_OPTIONAL_ADJUNCT_PREPARATION_PACKET_2026-05-28.md`
+
+The preserved owners do not change:
+
+- first-party HyperTwist remains the top-level owner for current derived-memory
+  compact-view surfaces
+- the landed `Phase 6R-M1` ledger remains the provenance substrate beneath this
+  packet
+- the landed `Phase 6R-M2` chronicle/continuity layer remains the current
+  history/open-work substrate beneath this packet
+- the landed `Phase 6R-M3` recall/shared-context layer remains the current
+  explicit retrieval and scoped-sharing substrate beneath this packet
+- the landed `Phase 6R-M4` cognitive-consolidation layer remains the current
+  reviewable derived-conclusion substrate beneath this packet
+- the landed `Phase 6R-M5` knowledge/note-posture layer remains the current
+  curated knowledge substrate beneath this packet
+- the VectorShell memory doctrine remains the external synchronization
+  entrypoint and authority map, not a frozen imported implementation
+
+## Landed scope
+
+The current code now owns a bounded first-party derived-memory and optional
+adjunct seam through:
+
+- canonical compact-summary, reduced-context-packet, digest-view, and
+  derived-adjunct state types in:
+  - `HyperTwistMemoryTypes.h`
+- first-party derived-adjunct derivation from current training repository state
+  over the already-landed `6R-M1`, `6R-M2`, `6R-M3`, `6R-M4`, and `6R-M5`
+  seams plus explicit context-assembly profile choice in:
+  - `UHyperTwistMemoryCoreLibrary`
+- current bounded active derived coverage for:
+  - memory overview summaries
+  - continuity/resume summaries
+  - knowledge/promotion summaries
+  - coach-resume reduced context packets
+  - knowledge-review reduced context packets
+  - coach-memory digest views
+  - knowledge-memory digest views
+- current bounded all-features-off correctness through:
+  - `Economic-Retention Mode` returning an empty-but-valid derived-adjunct
+    state with the derived-compacted gate inactive
+- current bounded derived-only and removability truth through:
+  - explicit `DerivedOnly` lane/authority on every landed `6R-M6` item
+  - explicit removability and all-features-off safety flags on the landed
+    `6R-M6` state
+- sample contract helpers in:
+  - `UHyperTwistContractLibrary::MakeSampleTrainingMemoryDerivedAdjunctState()`
+  - `UHyperTwistContractLibrary::SerializeMemoryDerivedAdjunctStateToJson(...)`
+  - `UHyperTwistContractLibrary::DeserializeMemoryDerivedAdjunctStateFromJson(...)`
+- focused automation coverage in:
+  - `HyperTwistMemoryPhase6RM6DerivedAdjunctContractTest.cpp`
+
+## Why this is still intentionally bounded
+
+This packet lands derived-only optional adjuncts only.
+
+Still deferred:
+
+- active user-authored note capture while ownership remains unjustified
+- any broader memory federation or rewrite beyond the bounded first-party
+  packet family
+
+## Validation
+
+Build validation:
+
+- `UnrealHyperTwistEditor Win64 Development`
+
+Focused automation validation:
+
+- `HyperTwist.FirstParty.Memory.Phase6R.M6.ActiveDerivedViews`
+- `HyperTwist.FirstParty.Memory.Phase6R.M6.AllFeaturesOffCorrectness`
+- `HyperTwist.FirstParty.Memory.Phase6R.M6.SerializationRoundTrip`
+
+Observed:
+
+- `3` focused `Phase 6R-M6` automation tests succeeded
+
+Non-blocking warnings stayed limited to the existing Unreal headless/editor
+noise, expected Python-stub regeneration noise, headless CEF/web-browser
+warnings, benign asset-registry/cache journal chatter during editor startup,
+and normal long headless-runtime controller timing warnings during automation.
+
+## Queue effect
+
+This packet consumes the current `Phase 6R-M6` implementation slice.
+
+The bounded first-party memory packet family is now landed through:
+
+- `6R-M1` contracts and ledger

+# HyperTwist Phase 6R-M6 first-party derived memory and optional adjunct preparation packet
+
+Created on `2026-05-28`
+
+## Status
+
+- first-party HyperTwist packet
+- source-backed `Phase 6R-M6` preparation/control slice
+
+## Purpose
+
+This packet scopes the sixth and final bounded first-party memory implementation
+slice under the canonical `Memory Lanes` doctrine.
+
+The granted slice is:
+
+- compact summaries
+- reduced context packets
+- optional digest views
+
+It is not:
+
+- a broad memory federation packet
+- a replay of `6R-M1`, `6R-M2`, `6R-M3`, `6R-M4`, or `6R-M5`
+- active user-authored note capture
+- any derived layer that can become the only stored representation
+
+## Current authority basis

+
+The preserved owners do not change here:
+
+- first-party HyperTwist remains the live owner for current derived-memory
+  compact views
+- the landed `Phase 6R-M1` ledger remains the provenance substrate beneath this
+  packet
+- the landed `Phase 6R-M2` chronicle/continuity layer remains the current
+  continuity substrate beneath this packet
+- the landed `Phase 6R-M3` recall/shared-context layer remains the current
+  retrieval and scoped-sharing substrate beneath this packet
+- the landed `Phase 6R-M4` cognitive-consolidation layer remains the current
+  derived-conclusion substrate beneath this packet
+- the landed `Phase 6R-M5` knowledge/note-posture layer remains the current
+  curated knowledge substrate beneath this packet
+- the VectorShell memory doctrine remains the external synchronization
+  entrypoint and authority map, not a frozen imported implementation
+
+## Granted family
+
+The bounded `Phase 6R-M6` slice may land:
+
+1. compact summaries over current first-party memory evidence
+2. reduced context packets over already-landed memory seams
+3. optional digest views over already-landed memory seams
+4. explicit all-features-off correctness
+5. explicit derived-only storage and removability truth
+6. sample contract and JSON round-trip coverage for the `6R-M6` state
+
+The packet must stay out of:
+
+- non-derived storage replacement
+- silent promotion of derived compact views into authoritative truth
+- active user-authored note capture
+
+## Proposed implementation shape
+
+Land the narrower first-party boundary through:
+
+- new memory types for:
+  - compact summaries
+  - reduced context packets
+  - digest views
+  - bounded derived-adjunct state
+- a memory-core derivation function over:
+  - the landed `6R-M1` ledger
+  - the landed `6R-M2` chronicle/continuity layer
+  - the landed `6R-M3` recall/shared-context layer
+  - the landed `6R-M4` cognitive-consolidation layer
+  - the landed `6R-M5` knowledge/notes layer
+  - explicit context-assembly profile choice
+- sample-contract helpers for:
+  - sample derived-adjunct derivation
+  - JSON serialization
+  - JSON deserialization
+- focused automation in:
+  - `HyperTwistMemoryPhase6RM6DerivedAdjunctContractTest.cpp`
+
+## Validation target
+
+Validate with:
+
+- Unreal build for `UnrealHyperTwistEditor Win64 Development`
+- focused automation:
+  - `HyperTwist.FirstParty.Memory.Phase6R.M6.ActiveDerivedViews`
+  - `HyperTwist.FirstParty.Memory.Phase6R.M6.AllFeaturesOffCorrectness`
+  - `HyperTwist.FirstParty.Memory.Phase6R.M6.SerializationRoundTrip`
+
+## Queue effect
+
+If this packet lands cleanly, the bounded first-party memory packet family is
+closed through derived-only optional adjuncts.
+
+After `Phase 6R-M6`:
+
+- do not reopen `6R-M1` through `6R-M6` as broad memory packets
+- any later memory work must be a narrower post-`M6` refinement or a separate
+  owner-justification pass
