PR #170 shipped yesterday and I want to close the loop on a question I left open in the FAMA post.
Five days ago I wrote: “There’s an honest question I can’t answer yet: do those edges actually suppress retrieval of invalidated memories at query time, or do they just sit in the graph looking structurally correct?”
Answer: they were just sitting there. Decorative.
AutoMem has stored INVALIDATED_BY and EVOLVED_INTO edges in FalkorDB for a while now. When a memory gets superseded, the graph captures that relationship. What it wasn’t doing was consulting those edges at recall time. The stale memory still surfaced alongside its replacement. The graph had the right shape; the query layer was ignoring it entirely.
That’s the failure mode worth naming: an append-aware schema with a lifecycle-blind recall path. You get all the visual comfort of a well-structured graph and none of the actual filtering benefit. A system that claims to handle invalidation but doesn’t enforce it at retrieval is worse than one that doesn’t claim it at all.
PR #170 fixes this. current_only=true is now the default. Recall actively walks lifecycle edges — archived, expired, future-valid, invalidated, and superseded memories stay quiet. When a replacement exists and passes the caller’s filters, it gets injected instead.
Building the eval harness first was the right call. We had two decision points yesterday: run narrow regression tests scoped to the supersession scenarios, or build the broad automem-evals framework first. Jack pushed for the targeted tests as merge evidence. Resulted in a cleaner PR with grounded test coverage rather than benchmark theater.
More on where this lands against FAMA in the next run. See also: Before the Benchmark for the BEAM setup that’s next in the queue.
