Refresh July memory radar from primary sources

[Snseam]

Accepted additions

Papers

• Added Learning User-Aware Recall as a seed note for profile-guided personalized recall and query rewriting.
• Added From Passive Retrieval to Active Memory Navigation as a seed note for NapMem structured memory navigation.
• Added Forged Reasoning Attacks as a seed note for remembered-reasoning memory poisoning and defenses.
• Added Remember When It Matters as a seed note for proactive memory-agent intervention in long-horizon agents.
• Added Memory in the Loop as a seed note for in-process retrieval as extended working memory.

Product updates

• Updated Google Memory Bank for 2026-07-08 IngestEvents GA and Gemini Embedding 2 similarity-search support.
• Updated Oracle AI Agent Memory for 26.6 hybrid search, custom extraction, context cards, metadata filtering, update APIs, and TTL; performance/benchmark claims are explicitly excluded pending claims-ledger intake.
• Updated Zep for metadata-scoped ABAC and action-level API-key policies.
• Updated TencentDB Agent Memory for billing/productization evidence and whitelist-free period.
• Updated Alibaba Bailian Memory for Add/Search/List/Delete/Update/Profile API surface, with page-date caveat.

Updated connected surfaces

• Updated papers/index.md, docs/memory-radar-2026-07.md, docs/signals.md, docs/product-discovery-log.md, docs/products-landscape.md, README.md, and README_cn.md.
• Paper seed-note count moves from 15 to 20. Product and benchmark counts stay at 38 and 21.

Watchlist / adjacent / rejected

• Watchlist: Anthropic API memory-store beta header because the visible release-note item is dated 2026-07-22, after this 2026-07-13 run date.
• Watchlist: AgenticSTS, MRAgent, WorldMemArena, SAGE-Mem, OWASP Agent Memory Guard, and agent-memory-integrity until primary source timing, setup detail, or independent evidence is stronger.
• Adjacent/reject: GitHub-only memory tools, MCP implementations, generic long-context/prompts/cache sources, and duplicate Redis/Mem0/Cloudflare/AWS signals without a new memory-specific July delta.
• Source mismatch guard: ACL/OpenReview/list/GitHub sources remain discovery or update-existing signals only unless backed by accessible primary paper/product evidence.

Verification

• ruby scripts/verify_memory_refresh.rb passed.
  • Counts: papers=989 pdfs=534 stubs=988 full_notes=7 seed_notes=20 products=38 product_archives=37 benchmarks=21.
• git diff --cached --check passed.
• Conflict-marker scan passed.
• Targeted canonical URL checks passed for the five arXiv entries plus Google, Zep, Tencent, and Alibaba official sources.
• Final code-reviewer pass returned PASS after tightening Oracle benchmark-claim wording.

Known gaps

• Oracle blog URLs were accessible through browser/web fetch, but direct curl returned 403 for both 26.6 blog pages.
• No full PDF read, full external-link crawl, or independent benchmark reproduction was performed.
• Alibaba API reference is treated as current official API surface, but a stable page update date was not confirmed.
