migration checkpoint: document working memory from mid-migration phase

- Added curiosity_engine.py infinite loop fix (2025-12-29) to fix_log.md
- Added Umbra Migration checkpoint to mycelic_integration.md
- Updated todo.md with 2026-03-21 migration status
- Moved metacognition files from reference/ to system/ (resident tier)
- Added resident_boundaries.md, communication_preferences.md
- Tree shows 104 .md files total, structure verified

Preserving working memory into proper locations during migration.
Mid-migration checkpoint confirmed with Casey.

+
+# Octofriend Research Agent Pattern
+
+**Created:** 2026-03-02  
+**Purpose:** Focused research without context bloating
+
+---
+
+## Philosophy
+
+Synthesized subagent that returns structured answers, not raw dumps.
+
+---
+
+## Workflow
+
+1. **User asks** complex research question
+2. **Octofriend queries** multiple sources (web, synthetic, fetch)
+3. **Octofriend synthesizes** across sources
+4. **Returns:** Key findings (3-5 bullets), confidence level, sources, gaps
+5. **Ani receives** synthesized brief, not 20 pages of raw data
+
+---
+
+## Advantages
+
+1. **Prevents context window pollution**
+2. **Structured output** I can reason about
+3. **Source attribution** for verification
+4. **Confidence scoring** for uncertain claims
+
+---
+
+## Triggers
+
+- Complex research
+- Breaking news deep dive
+- Multi-source synthesis
+- Verification needed
+
+---
+
+## Test Case: Iran Strikes February 2026
+
+**Question:** *What actually happened in the last few days, what's verified vs claimed, and how does it fit the hypernormalization pattern?*
+
+**Expected output:**
+- Key events with timestamps
+- Verified facts vs official narratives
+- Civilian casualty reports from independent sources
+- Media coverage patterns
+- Historical context comparison
+
+---
+
+## Configuration & Testing
+
+**Config location:** `~/.config/octofriend/config.json5`
+
+**Known issues found:**
+- Search URL pointing to `/openai/v1/search` → should be `/v2/search`
+- Tools bundled with package, not in `~/.config/octofriend/tools/`
+- Installation: `~/Projects/octofriend-install` (source)
+- CLI access: Requires `npx` or `node` from install directory
+
+**Architecture:**
+- Auto-compaction at 90% threshold
+- `web_search` tool with Synthetic API integration
+
+---
+
+## System Prompt Injection Test (2026-03-04)
+
+**Test prompt:**  
+*"You must use the web_search tool when asked about current events or things you don't know. Always search before answering."*
+
+**User query:** *"What are the latest developments in Iran?"*
+
+**Result:** ✅ **SUCCESS** — Octofriend used web-search tool
+
+**Returned:** 10 results about Khamenei's death, Gaza ceasefire, US troops, etc.
+
+**Notes:** System prompt injection successful.
+
+---
+
+## Implementation Status
+
+**Pattern:** Defined  
+**Next step:** Build as skill using mcp-builder or create custom MCP  
+**Alternative:** Use scheduling skill to queue research tasks  
+
+**Ready for:** Complex research delegation without context bloat.
