Normal search ignores archived sources, but `MemoryStore::provenance_sources()` can traverse edges and return archived evidence for explicit provenance inspection. 51 + 52 + The real agent harness exposes this through `memory_provenance(id, depth?)`, and `edit_memory(id, superseded_by)` creates a `supersedes` edge while archiving the older memory. 53 + 54 + Recall and injected-memory text exposes typed edge counts as hints, for example `[derived_from:3,supersedes:1]`. These hints do not auto-traverse sources; they tell the agent when `memory_provenance(id)` is available and which edge policy is relevant. 55 + 56 + `list_memories(include_inactive=true)` exposes recent inactive records with status, source, and edge hints for reflection/cleanup without changing normal active-only recall behavior. 31 57 32 58 ## Offline Eval Dataset 33 59
