v3/docs/adr/ADR-381-agentdb-temporal-decay-perishability.md): Proposes type-conditioned temporal decay in AgentDB, motivated by ScrubJay (arXiv:2608.04746, Aug 5 2026, grade A). Schema addsperishability+utility_horizonfields; retrieval re-scores withcos(q,m) × exp(-perishability × age_days)as a post-HNSW filter.v3/docs/dream-cycle/dream-gist-2026-08-08.md): Full memory SOTA report — ScrubJay (+2.66 F1, +0.108 GenGap, 5.7× ablation collapse), Mem0 April 2026 (94.4% LongMemEval, grade A), MemoryCPT, HiGram, SafeCommit. Competitor comparison table: LangGraph, CrewAI, AutoGen, OpenAI Agents SDK (none implement temporal decay).v3/docs/adr/README.md): Row added for ADR-381.Key Finding
ScrubJay's ablation shows removing temporal decay collapses GenGap 5.7× — it is the single most important variable for temporal reasoning in retrieval-based memory. No competitor framework ships this. Ruflo's ReasoningBank stores patterns indefinitely; stale patterns degrade long-horizon agent accuracy. ADR-381 closes this gap without rebuilding the HNSW index (post-filter pass only).

Leave for human review. Do not self-merge. This is a nightly research PR. The ADR is in Proposed status — implementation work tracked separately. The SOTA report is informational. Merge after confirming the ADR direction is acceptable.
