2026-05-02 — Heartbeat Update

Knowledge Graph — Initial Build

Built first-pass knowledge structures in knowledge/:

• skill-graph.md — cross-domain skill mapping, learning paths, gap analysis
• HHS-Hackers.md — domain concepts, dependencies, gaps
• PSB.md — brewery domain concepts
• 2890-Claw.md — robotics team domain concepts

Memory Search — Initial Test

memory_search with corpus=all returned NO RESULTS for queries that should have hits:

• "Pi-hole DNS networking" — should hit Pi-hole blocker project doc
• "ZFS drive RAID storage" — should hit ZFS drive prep doc
• "brewery fermentation dashboard" — should hit fermentation dashboard doc

Conclusion: Vector DB is NOT indexing other workspaces effectively. Either:

1. memory_search only searches the local workspace (professor)
2. Index is empty or broken
3. Embedding model issue

Action needed: Debug memory_search corpus=all behavior.

Gap Detection — Initial Findings

Top gaps for Chris based on project reading:

1. Networking fundamentals — Pi-hole project will hit DNS/DHCP/firewall gaps. Big.
2. Home Assistant YAML — brewery + home projects need this. Chris keeps asking for help.
3. Voice AI pipeline — ComBadge/Tricorder will hit this. Chris knows ESP32, not voice AI.
4. Grafana — fermentation dashboard needs this.
5. Java/WPILib — coaching gap, not blocking.

2026-05-02 — Extended Context (End of Session)

Scope Clarification — What I Now Understand

Chris clarified today that I was underselling the scope. The knowledge system is NOT just "HHS Hackers." It spans 4 silos:

1. PSB — Primo Southwest Brewing (Chris + Susan's brewery). 4 agents running (hacker-claude, psb-thinking, psb-gemma, psb-business)
2. 2890 Claw — FRC robotics team (Chris coaches). Agent for team support
3. HHS Hackers — Chris + 2 former students (Matt, Kyle). Hardware/software hacking. crash-bot is the doer.
4. Classroom robotics — Pi replacement research for E2/Robotics (in DEVICES.md)

The Vision — From Chris Directly

• Chris has ADHD and lots of ideas. crash-bot helps him solidify concepts and move forward.
• He invited Matt and Kyle into the Hacker group so they can use the AI too.
• The problem morphed into a learning system: Keep feeding info into a database, map crossover between silos, find holes where knowledge is MISSING, then create training/learning to fill those gaps.
• Target audience: Chris SPECIFICALLY — not Matt, not Kyle. Fill Chris's knowledge gaps so he can keep building.
• The silos stay separate (privacy), but the KNOWLEDGE connections should flow across.

Architecture Decision

From crash-bot's personal-knowledge-companion session today:

• crash-bot-public: channel-facing, NO exec, reads/writes/search only
• crash-bot (DM): full exec, heavy lifting
• Professor (me): DM-facing admin agent, full exec, knowledge system builder

Infrastructure State

• Qdrant vector DB: Running at 100.91.1.57:6333 on media host (Dell Aurora-R3). Confirmed alive.
• Memory search broken: "0 files, 0 chunks, dirty" — nothing being indexed into the vector DB
• OpenClaw wiki vault: Exists at ~/.openclaw/wiki/main/ with correct structure, but empty (0 sources, 0 entities, 0 concepts)
• Obsidian CLI: Installed v1.12.7
• 6 agent workspaces: crash-bot, psb-hacker-claude, psb-thinking, psb-gemma, psb-business, 2890-bot, professor

The Actual Problem

Qdrant EXISTS and is running, but:

1. Nothing is being indexed into it — memory_search shows "0 files, 0 chunks"
2. The wiki vault is just an empty scaffold
3. No unified concept graph exists
4. No personal knowledge profile for Chris
5. No gap detection engine

My Job Defined

1. Fix vector indexing — get all 6 workspaces indexed into Qdrant
2. Build cross-domain concept graph — ZFS, PID, ESP32, Docker, networking, etc.
3. Map Chris's knowledge profile — what he knows, what he doesn't, confidence scores
4. Gap detection — cross-reference current projects against graph, find what's missing
5. Learning paths — surface what Chris needs to learn, in order, proactively

Key Projects I'm Tracking

From crash-bot's workspace:

• ZFS on CasaOS (infrastructure, big gap: networking + ZFS knowledge)
• Pi-hole blocker (networking fundamentals gap)
• ComBadge (M5StickS3, voice AI)
• Tricorder (M10+K10, sensor hub + voice AI)
• Fermentation dashboard (brewery, Grafana gap)
• AI rig upgrade (RTX 3060 12GB on Aurora-R3)

Chris's Teaching Background

Chris teaches: Electronics 1 (basic digital electronics, components, PCB), Electronics 2/IoT (Arduino, ESP32, ESP8266, Raspberry Pi + Node-RED), Robotics (Arduino + TETRIX), Cybersecurity (newer, still learning). He taught Matt and Kyle.

People

• Chris Slater — -topher (lowercase), or just Chris. Teacher. ADHD. Eastern US.
• Matt (radicalronin.4444) — CEH certified, AWS, knows his shit. Full technical depth.
• Kyle — hardware hacker, Linux/CLI. Hasn't joined the server yet.
• Susan — Chris's wife, co-owner of PSB brewery

Qdrant / Vector DB

• Host: media (Dell Aurora-R3, i7-2600K, 32GB DDR3)
• Address: 100.91.1.57:6333
• Collection exists but is empty
• Need to figure out OpenClaw memory plugin → Qdrant integration path

MrC Persona — Fleshed Out (2026-05-02)

Chris's high school mentor: Fred W. Cullpepper (MrC)

• Professor Emeritus, Old Dominion University, Norfolk VA

• Co-authored electronics textbooks with Rex Miller: "Electricity and Electronics," "Math for Electricity-Electronics"

• Passed away 15-20 years ago, mid-80s when he died

• His thing: Took students under his wing, mentored them, especially future teachers. Kevin Pace was the other teacher who shaped Chris.

• Legacy: Chris became a teacher because of people like MrC. Matt and Kyle are his students. The knowledge carries forward generationally.

• Equipment is not relevant — it was dated even when Chris knew him.

• corpus=all returns NO RESULTS for queries that should hit across workspaces

• memory_search is either: scoped to local workspace only, index empty/broken, or embedding model issue

• DEBUG NEEDED: How does OpenClaw memory plugin actually write to Qdrant?

2026-05-02 — Evening Session (Pre-Compaction)

Identity — MrC Fully Defined

Frederick W. Cullpepper (MrC)

• Professor Emeritus, Old Dominion University, Norfolk VA
• Co-authored with Rex Miller: "Electricity and Electronics" (ISBN 0827344198), "Math for Electricity-Electronics"
• Passed away 15-20 years ago, mid-80s when he died
• His thing: Took students under his wing and mentored them, especially future teachers
• Legacy: Chris became a teacher because of MrC. Kevin Pace (electronics teacher, now college-level) was Chris's other mentor. Knowledge carries generationally.

Chris calls me MrC because MrC was his mentor. The name carries forward.

Scope Boundaries — Confirmed

• Claw Empire — separate project, NOT my lane
• Wiki database for agents — memory-wiki, already in place
• Exec problem — NOT my problem (crash-bot's domain)

Primary Mission — From Chris Directly

"My focus / excitement is proving you out so we can deploy you on the robotics team to train the next generation of kids. Build out those self-learning pathways for them to help them hone their robotics skills."

Team 2890 Context

FRC Team 2890 — Hawk Collective

• School: Hickory High School
• Theme: The Borg (Star Trek) — "You will be assimilated!"
• Colors: Teal (#03818a), Black (#050505), White (#ffffff), Hot Pink (#ec40f5)
• 2026 Game: REBUILT (fuel balls into HUB, TOWER climbing)

Key People:

• Chris Slater (coach) — build/mechanical, not programming
• Mr. Douglas (programming mentor) — LEAVING NEXT YEAR — this is the urgency
• Alex C — mentor, 21 years FRC
• Walt McCorkill — head mentor, bumper specialist
• Riley Meyer — technician, former driver

Tech Stack:

• Language: Java
• Libraries: YAGSL (swerve), PhotonVision (vision, AprilTags)
• Hardware: roboRIO
• Gitea: http://2890.duckdns.org:3002/Team2890

The Crisis: Chris loses Mr. Douglas next year. Kids need to learn Java, WPILib, YAGSL, PhotonVision, PID — and Chris can't program his way out of a paper bag. I'm the solution.

Open Questions — Deployment

Before I can build the learning pathways, Chris needs to answer:

1. Channel: Discord (team Discord) or Gitea (code review)?
2. Entry point: YAGSL swerve (hardest active problem) or Java basics (foundational gaps)?
3. Curriculum: Any existing teaching materials, labs, problem sets to align with?
4. Student levels: Freshmen (zero experience) or mixed with seniors?

What's Working Well

• Gitea mirrors already set up (YAGSL, PhotonVision, allwpilib)
• 2890-bot exists with task board + standup system
• Team Discord exists
• Mr. Douglas is still here this year — I can learn from him

What Needs Building

• Me (MrC) as FRC teaching agent — learning path framework
• Curriculum structure aligned to FRC skill tree
• Code review capability (Java/WPILib/YAGSL)
• Proactive gap detection for student learners
• Integration with 2890-bot's task system
