Give Hermes a long-term memory graph

Goal: Replace a capped markdown scratchpad with memory that knows what is stale.
Setup: agents used in source: Hermes Agent; tools/MCPs stated: Hindsight, Docker, Ollama.
Steps:
1. Run the Hindsight memory provider plugin in a Docker container next to Hermes.
2. Do the bulk seeding with a cheap cloud model (here ~2 hours, 537 calls, $0.85).
3. Switch daily extraction to a local model with a lighter fallback machine.
4. When a fact changes, mark the old memory invalidated with a reason instead of writing more text to contradict it.
Rules: ask me before anything irreversible (sending, posting, paying, deleting); don’t invent data, results or tools I haven’t given you; tell me what you couldn’t verify.
