Critical Solutions

• N8N + Claude Code Automated Server Monitoring System - Built automated server health monitoring with N8N and Claude Code headless mode. (n8n, claude-code, automation)
• Docker MCP Gateway secrets workaround for headless Docker Engine (no Docker Desktop) - docker mcp secret set requires Docker Desktop's docker-pass CLI plugin (l... (docker-mcp-gateway, mcp, secrets)
• Break circular imports by extracting shared models to models.py (python, circular-imports, architecture)
• Expanded health monitoring to 6 servers with per-server SSH user support - Expanded CT 302 health check coverage from 3 to 6 monitored servers. (monitoring, claude-runner-monitoring, homelab)

• Gitea Actions runner can't clone self-hosted composite actions - auth + cache fix - Problem: Gitea Actions runner fails to clone composite actions from cal/gitea... (gitea, ci-cd, actions)
• CORE.md auto-load via MEMORY.md symlinks - Solved unreliable CORE.md loading at session start. (cognitive-memory, claude-code, automation)

Active Decisions

• Migrated Gitea operations from tea CLI to gitea-mcp MCP server - Previously, all Gitea operations in Claude Code sessions used the tea CLI v... (gitea, mcp, claude-code)
• FullCard Migration: card_layout.py ported to card-creation repo (paper-dynasty, card-creation, card_layout)
• FullCard migration: database-side schema + router changes (paper-dynasty, database, db_engine)
• Migrated from Docker MCP Gateway (LXC 303) back to local MCP servers - LXC 303 (10.10.0.231) was running Docker MCP Gateway serving n8n and Gitea MC... (mcp, docker-mcp-gateway, claude-code)
• No re-exports when refactoring imports — update call sites directly (python, refactoring, architecture)
• Resume: Migrated from Google Slides to RenderCV (YAML-to-PDF) - Cal's professional resume was previously maintained in Google Slides and expo... (resume, rendercv, migration)
• n8n Server Health Monitor refactored to master + sub-workflow pattern - Refactored the monolithic "Server Health Monitor - Claude Code" n8n workflow... (n8n, monitoring, homelab)
• Proxmox guest cleanup: removed 14 VMs/LXCs before Phase 2 upgrade - Removed 14 unused/duplicate guests before PVE 8->9 upgrade. (proxmox, homelab, infrastructure)
• Switched embedding model from nomic-embed-text to qwen3-embedding:8b - Upgraded Ollama embedding model from nomic-embed-text (137M params, 768d, F16... (cognitive-memory, ollama, embedding)
• SBA Scout Python-to-Rust TUI migration: recommended stack and approach - SBA Scout is a Python TUI app using Textual + SQLAlchemy + httpx + pydantic-s... (sba-scout, rust, migration)

Key Fixes

• Claude Code MCP user-scope config is ~/.claude.json, not ~/.claude/.mcp.json - Confusion about where Claude Code stores user-scoped MCP server configurations. (claude-code, mcp, configuration)
• Fix: Float/Decimal type mismatch in card builders (card-creation repo) (paper-dynasty, card-creation, card_builder)
• MCP manager was writing to wrong config path - ~/.claude/.mcp.json instead of project .mcp.json - The mcp-manager skill's mcp_control.py was reading/writing `~/.claude/.mcp.... (mcp, claude-code, mcp-manager)
• pd-cards retrosheet --season-pct defaults to 1.0, overrides retrosheet_data.py config - The pd-cards retrosheet process command defaults --season-pct to 1.0. (paper-dynasty, cli, pd-cards)
• PD API /players endpoint: filter by cardset uses "cardset_id" not "cardset" - When querying the Paper Dynasty API /players endpoint, using the query para... (paper-dynasty, api, debugging)
• [homelab] Session: automation, configuration, debugging, deployment, feature, fix, tooling - Files edited (1): (homelab, automation, configuration)
• [homelab] Session: configuration, creation, debugging, deployment, fix, tooling - Files edited (1): (homelab, configuration, creation)
• Fix: PitchingCardRatingsModel xcheck defaults must be zeroed in new_ratings (paper-dynasty, card-creation, pitchers)
• Fix: Prevent duplicate POSTs when audit update fails after successful delivery in outbound-event-handler - esb-monorepo — TAC outbound-event-handler (GCF) (esb-monorepo, tac, outbound-event-handler)
• Fix: UTC/CST timezone ambiguity in transaction freeze/thaw scheduling — utils/timezone.py - major-domo / discord-app-v2 (major-domo, timezone, transaction-freeze)
