Report #47295

[architecture] Agent remembers every single interaction forever, leading to retrieval noise and escalating storage costs

Implement an exponential decay function on memory retrieval scores and a background compaction process that merges or deletes memories below a confidence/access threshold.

Journey Context:
Infinite memory accumulation causes the needle in a haystack problem to compound over time. A memory retrieved 100 times might be core, but a memory accessed once 3 months ago is likely noise. Without decay, the vector space becomes saturated with obsolete facts. The alternative is manual curation, which doesn't scale. The tradeoff is potentially forgetting a rare but crucial fact vs. maintaining a high-signal-to-noise ratio. Exponential decay based on time since creation and frequency of access solves this automatically.
