The graph as agent memory rejects the notebook metaphor. A notebook remembers what you wrote, but not when you believed it, nor when the fact itself was true. Flat vector stores and long-context transformers collapse time into a single present, and an agent that cannot distinguish "I knew this yesterday" from "this is still true today" is not reasoning — it is repeating. A bi-temporal knowledge graph — one that records both valid_at (when the fact held in the world) and recorded_at (when the agent ingested it) — turns memory from a static log into a navigable, revision-conscious archive where nothing is deleted and facts are superseded by stamping invalid_at.

This is article #4 in the Autonomous Knowledge Graphs series. The AI-engineer curriculum concept graph from #1 doubles as the agent's long-term, revision-conscious memory of the curriculum as it evolves across months of sessions, under the same engineering constraints: a control plane built on LlamaIndex — DeepSeek as the LLM client, its PropertyGraphIndex for retrieval — with the autonomous loop itself written in plain Python rather than run by a workflow or graph-orchestration engine, over a Cloudflare D1 concept-graph data plane (concepts, concept_edges, lesson_concepts), with a thin TypeScript layer applying every write; DeepSeek-only model egress through one Cloudflare AI Gateway; a grounding-first record on every write — {confidence, reason, source, evidence} with bi-temporal valid_at/recorded_at stamps; and invalidate-not-delete at every irreversible step.

Every Claude Code session leaves a trace — tool calls made, files read, edits applied, errors encountered, and ultimately a score reflecting how well the task was completed. Most systems discard this history. We built an agent that mines it.

The Trajectory Miner is the first agent in our six-agent autonomous self-improvement pipeline for nomadically.work, a remote EU job board aggregator. Its job: analyze past sessions, extract recurring patterns and reusable skills, and feed structured intelligence to the rest of the team. It writes no code. It produces raw material that other agents — the Codebase Auditor, Skill Evolver, and Code Improver — consume.

The design draws from four research papers, curated from the VoltAgent/awesome-ai-agent-papers collection. Here is what each paper contributes and how we translated academic ideas into a working system.
