PARENT: Memory Research Atlas — Pre-T1 (#375)
PRIORITY: HIGH

RUNE REQUIREMENTS AFFECTED: R7,R9,R11,R27,R29; delta-only recheck beyond the 2026-09-19 closure (MemOS, MemoryOS, LangMem, changed versions)

RESEARCH PIPELINE: ISSUE → INWARD → OUTWARD → APPLICABILITY → INNOVATION → ADVERSARIAL → SYNTHESIS → QUALIFY

EXPECTED OUTPUT: durable research artifact (research/memory-atlas/families/), mechanism classifications (COVERED/ADOPT/ADAPT/EXPERIMENT/FUTURE/REJECT/NOT_RELEVANT) with confidence + architecture impact, unresolved questions, architecture-changing flag.

NO-BUILD BOUNDARY: research only — no production implementation.

CLOSURE FORMAT: per Atlas mandate §2 (domain, requirements, current equivalent, mechanisms, evidence, costs, failure modes, LLM-dependency effect, offline suitability, century-scale implications, architecture impact, applicability, innovation, classification, confidence, unknowns, T1-change flag, proof-required, rejection criterion).

⚠️ Priority gate: this issue has no priority. Assign exactly one of P0 — critical (spine/correctness/blocks), P1 — high (material value or real defect), P2 — medium (quality/consolidation), P3 — low (measurement/deferred). An issue without a priority is not filed.

Research qualification — Memory Research Atlas

This child domain is researched and qualified. Findings, mechanism classifications (COVERED/ADOPT/ADAPT/EXPERIMENT/FUTURE/REJECT with confidence + architecture impact), adversarial risks, and T1-impact flags are persisted in the durable artifact:

research/memory-atlas/families/ (see FINAL_REPORT.md and the parent epic #375 for cross-family synthesis).

Verdict fed into the parent Atlas requirement-coverage matrix and architecture-changer registry. NO-BUILD boundary respected: no production implementation. Child closes COMPLETE.

R1_DEEP_RESEARCH_COMPLETE

Domain: Modern Agent / LLM Memory Systems (#379, delta-only R1)

Pipeline: ISSUE PASS (10 subquestions, 10 R0 claims, 4 falsifiers) · INWARD PASS (T0/T0.1 + prior closure) · OUTWARD PASS (9 sections, 25-entry source ledger) · APPLICABILITY PASS (10 transfer chains) · INNOVATION PASS (4 candidates) · ADVERSARIAL PASS (independent; 8 attacks: 1 strong success, 4 partial, 3 failures) · SYNTHESIS PASS (13-row matrix) · QUALIFY PASS (14 mechanisms)

Research depth: 25 new primary sources verified · 1 benchmark audit · 3 documentation audits · 8 security/attack papers · 4 architecture pivots documented · 5 convergence axes identified

R0 reconciliation: CONFIRMED 4 · REFINED 5 · OVERTURNED 0 · STILL_UNKNOWN 0 · Sum = 10

Architecture-changing findings:

  1. Revocation enforcement at retrieval: ADOPT (no deployed system enforces; Rune's supersession schema ready)
  2. Model-version-per-vector + raw-source retention: ADOPT (portability study quantified 9.9-13.3pp loss)
  3. Environment-probing curation: EXPERIMENT (39%→73% pass rate in Copilot SDK)
  4. Letta deprecated vector archival memory for git-backed file memory — validates Rune's file-first direction
  5. Vendor benchmarks (LoCoMo, LongMemEval) documented as unreliable (6.4% wrong-key, judge 63% wrong-accept) — never cite vendor numbers as authority
  6. Parametric memory (Titans/MemoryLLM) is a genuine divergent line at a different stack layer — FUTURE

Experiments: revocation-guard A/B; model-migration parity; environment-probing pass-rate

Remaining unknowns: Hindsight 91.4% needs disinterested replication; Mem0 arbiter longitudinal error unmeasured; MemOS skill crystallization unbenchmarked independently; parametric memory practicality

Evidence saturation: EVIDENCE SATURATION REACHED (10 search branches; late-stage predominantly repetition; 0 unincorporated contradictions)

Mutation audit: PRODUCTION_MUTATION = NONE

Canonical folder: research/memory-atlas-r1/D-modern-agent-llm-memory-systems/
Domain master: D_MODERN_AGENT_LLM_MEMORY_SYSTEMS_R1_MASTER.md
