Summary

• 8 items, all primary-source verified.
• Heavy day on agent memory (MEMTIER, ScrapMem) and on-device multi-agent infra (QKVShare KV-cache handoff). New benchmarks for coding/workspace agents (Workspace-Bench 1.0) and scientific-research agents (AstaBench refresh). One frontier/local item: Gemma 4 multi-token-prediction drafters with measured Apple Silicon speedups.
• Local-fit pick of the day: Gemma 4 26B MoE (3.8B active) + MTP drafter via MLX — ~2.2× speedup at batch 4–8 on Apple Silicon, comfortably runnable on the M5 Max at Q4 with 32K usable context.

Focus areas covered

Agent memory · Context engineering · Agent orchestration · Long-running loops · Tools & connectors · Frontier models · Local & open models (Apple Silicon) · Coding agents · Evaluation

Conflicts flagged (1)

• Opus 4.7 appears on AstaBench (58.0%) — the first measured benchmark we've seen tied to that handle. Relationship to "Claude Mythos Preview" (introduced via BioMysteryBench in the 5/4 ledger) is unresolved. Tracked, will revisit.

Notes

• OpenAI news/research blog returned 403 — flagged for retry next run.
• r/LocalLLaMA inaccessible — relied on HN Algolia + HF Daily for discovery.
• AstaBench update is from Apr 30 (~6 days old), included as a missed-but-still-highly-relevant item per the rubric (introduces Opus 4.7 benchmark).
