memory: create projects index and reorganize active vs reference

- Create system/projects_index.md (signpost to all work locations)
- Move non-active files from system to reference:
  - discord.md, discord_formatting_guide.md
  - conversation_search_guide.md
  - research_workflow.md, subagent_usage_guide.md
- Active projects stay in system: community_ade, project_paths, compass, etc.
- Reference projects on-demand: infrastructure, research archives

Pattern: system = always-loaded active work, reference = load-on-demand

+# Research Workflow
+
+## Method: Synthetic Search Skill
+
+For web research tasks, use the `synthetic_search` skill to explore topics and generate comprehensive reports.
+
+### Command Syntax
+```
+/synthetic-search
+```
+
+Or via Task tool with researcher subagent.
+
+### Output
+Specify file output for research results:
+- `/home/ani/Projects/lettabot-v017/research/[topic]-[date].md`
+- Or similar path in appropriate project directory
+
+---
+
+## Current Research Queue
+
+### 1. Gitea Alternatives (Self-Hosted)
+**Status:** Pending
+**Goal:** Find and compare self-hosted Git alternatives to Gitea
+**Approach:** 
+- Search for "self-hosted git platforms 2025"
+- Compare: GitLab CE, Gitea, Forgejo, SourceHut, etc.
+- Evaluate: Resource usage, features, maintenance burden
+
+### 2. Hindsight Setup
+**Status:** Running but disconnected, needs configuration
+**Goal:** Complete setup and integration
+**Location:** Check /home/ani/Projects/ for hindsight installation
+
+### 3. Reflection Agents / Aster Fix
+**Status:** Needs testing/debugging
+**Goal:** Get reflection agents working properly
+
+### 4. Cameron's Note Program Integration
+**Status:** Needs to be added to Letta
+**Goal:** Import/note-taking functionality
+

+
+## Workflow Pattern
+
+1. **Research Phase**
+   - Use synthetic search to gather information
+   - Save results to file
+
+2. **Analysis Phase** 
+   - Review findings
+   - Document in memory or project files
+
+3. **Implementation Phase**
+   - Execute based on research
+   - Update todos as completed
