Refresh August memory radar evidence

[Snseam]

Accepted additions

Papers / seed notes:

• Zero-Mem: zero-token memory operations for LLM agents (papers/zero-mem-zero-token-memory-operations.md).
• Memory Provenance Laundering in LLM Agents (papers/memory-provenance-laundering.md).
• MemHarness: Memory Is Reconstructed, Not Replayed (papers/memharness-memory-reconstructed-not-replayed.md).
• Filesystem-Based Memory for LLM Agents (papers/filesystem-based-memory-llm-agents.md).

Benchmarks / origin-protocol seed notes:

• MemSecBench (benchmarks/memsecbench.md) with memsecbench-origin-2026 claims-ledger event.
• Setoka (benchmarks/setoka.md) with setoka-origin-2026 claims-ledger event.

Updated existing entries

• Google Agent Platform Memory Bank: setup/topics/TTL/runtime integration behavior.
• Mem0: n8n/Zapier workflow integration behavior.
• Zep: valid-time ordering, opaque page token, and is_null date filter behavior.
• AWS AgentCore Memory: Bedrock Agents Classic migration / AgentCore runtime memory signal.
• TencentDB Agent Memory: v2 beta/team-memory signal kept as update/watchlist, with vendor benchmark claims bounded.
• Hindsight: v0.8.6 list_memory_units ingest-age filtering behavior.

Connected surfaces updated: README / README_cn counts and latest-radar links, docs/README.md, papers/index.md, benchmarks/index.md, benchmarks/claims/claims.yaml, docs/benchmarks-landscape.md, docs/memory-radar-2026-08.md, docs/signals.md, docs/product-discovery-log.md, docs/products-landscape.md, and affected product notes.

Watchlist

• MemTX / MemTxn / ChronoMem: transactional commit, source-supported updates, and semantic rollback are strong governance candidates for the next full source read.
• MemLens / MemChain / Know It, Act on It / Beyond Retrieval Analytic Memory: strong paper candidates retained for later expansion.
• Databricks Managed Agent Memory / Memora: already covered by open PR Refresh weekly agent memory radar evidence #18, so this branch does not duplicate those entries.
• OWASP Agent Memory Guard / Mnemoverse MCP Memory / AMBIENT: useful discovery signals with primary follow-up URLs, but not promoted without full source read.
• Letta Memory Filesystem: relevant feature signal, but date was not sufficiently verified in the weekly window.
• inspeximus / ai-memory-mcp / memgres / sqlite-graph-memory: GitHub-only or vendor/self-claimed benchmark signals.

Adjacent / rejected

• Microsoft Foundry Local Agentic Retrieval: adjacent; boundary with existing Foundry Agent Service Memory is unclear.
• HAM-VLN / TransMem / hidden-state memory items: adjacent; closer to embodied navigation, hidden-state/context compression, or model-internal memory than core agent-memory lifecycle.
• GitHub stars, README benchmark numbers, vendor benchmark rows, MCP/catalog placement: rejected as performance or quality evidence; discovery only.

Source mismatches

No new mismatched canonical title/URL pair was promoted. All accepted paper/benchmark additions use direct arXiv URLs; product updates use official docs/changelog/release URLs. Search-snippet dates were not used as canonical source facts.

Verification

• ruby scripts/verify_memory_refresh.rb passed: papers=989 pdfs=534 stubs=988 full_notes=7 seed_notes=19 products=38 product_archives=37 benchmarks=23.
• git diff --cached --check passed before commit.
• Conflict-marker scan passed.
• benchmarks/claims/claims.yaml parsed successfully via the repo verifier.
• Targeted canonical URL checks returned HTTP 200 for accepted arXiv URLs and updated official product/watchlist URLs.
• Final code-reviewer pass returned PASS; one low consistency note was fixed before commit.

Known gaps

• Seed notes are not full PDF reads; no reported paper scores or product benchmark claims were promoted.
• No full external link crawl was run.
• Open PR Refresh weekly agent memory radar evidence #18 remains separate and unmerged; this branch explicitly avoids duplicating its Databricks/Memora coverage.
• Several strong August paper candidates remain watchlist to keep this weekly diff bounded and reviewable.
