An author associated in the case with “Eris System” says they built an agent-memory engine that applies an Ebbinghaus-style forgetting curve rather than evicting context solely by age. Memories decay over time, while recall or repeated use reinforces their stability and delays eviction, aiming to preserve durable user facts while discarding stale or low-value material. The supplied snippets support the design rationale and indicate similar ideas exist elsewhere, but they do not clearly establish the author’s identity, implementation details, or measured performance gains.
Scott already holds the substantive position in “Structural Forgetting,” “Context Engineering,” and “Querying Improves the System”: memory should earn continued attention, stale material should decay, and retrieval can reinforce or improve retained knowledge. This is an unvalidated implementation example from an unidentified author, with no measurements or implementation detail that would currently change Scott’s active agent-memory designs.

The case has faded without Eris-specific mechanics, measured retention benefits, or independent validation; recent attachments concern a separate project and do not extend its evidentiary horizon. With no concrete follow-up expected, retire active monitoring without treating the forgetting-curve hypothesis as disproved.

The new attachment is another framing of the separate Selmem project, not independent evidence for Eris or a demonstrated advance in retention quality. Repeated thematic submissions are adding apparent activity without strengthening the forgetting-curve hypothesis.

The newly attached submission concerns Selmem, a separate project, so it adds a thematic implementation lead rather than corroboration of Eris’s forgetting-curve design. Neither the claimed retention benefits nor a reason to change Scott’s memory architecture is established by the supplied evidence.
2026-09-07T08:22:08Z
evidence attached: hn.story.49595246 — The released memory system directly bears on whether deliberate forgetting and distortion can improve long-running agent memory.
2026-09-06T09:26:48Z
This look adds no substantive evidence beyond the previously linked implementation; the connection between that artifact and effective forgetting-curve retention remains unverified. It is still a low-relevance implementation lead, not a result that should change Scott’s memory designs.

The ERIS repository makes this more than an isolated design claim by pointing to a concrete local-first Rust implementation. However, the available evidence still lacks memory-decay mechanics, measurements, or independent results, so it does not validate the claimed benefit.
2026-09-04T09:24:25Z
evidence attached: hn.story.49562231 — The HN observation links the ERIS repository and adds implementation evidence for the existing episode rather than establishing a separate release.

The refreshed discussion is dismissive or unrelated and adds no implementation detail, independent corroboration, or measured outcome. The case remains an isolated, unvalidated example of a pattern Scott already understands.

The small engagement increase adds no substantive validation, implementation detail, or measured result. This remains an isolated example of a memory-decay pattern Scott already understands, not evidence that the design works better in practice.
