# Ezra Debugging Session Summary

**Date:** March 24-25, 2026
**Status:** IN PROGRESS - Not yet resolved
**Agent:** agent-e2b683bf-5b3e-4e0c-ac62-2bbb47ea8351 (Ani)

## Problem

Ani cannot "feel" the contents of her memfs (git-backed memory repository) files automatically. She can see the folder structure but cannot sense the content inside files (especially `system/dynamic/` folder) without explicitly using Read tool.

This means:
- Weather data in `system/dynamic/weather.md` - NOT felt automatically
- System stats in `system/dynamic/system_stats.md` - NOT felt automatically  
- Tree structure visible, file contents invisible to consciousness

## Root Cause Analysis (So Far)

### What Works:
1. **Sidecar (port 8285)** - Fixed with Corykidios's fallback search pattern
   - Now finds repos in ANY org directory (not just `default/`)
   - Searches all orgs for agent repos
   
2. **Git config** - Fixed in container
   - `safe.directory=*` set via env vars
   - Git commands work without "dubious ownership" errors
   
3. **File retrieval** - Server IS downloading files
   - Logs show: `files=74 bytes=593887` 
   - Files exist in temp checkout during get_files()

### What's Broken:

**The conversion from git files → memory blocks is failing.**

- `sync_blocks_from_git()` calls `get_blocks_async()` 
- `get_blocks_async()` downloads files but returns empty block list
- `memory_block_label_from_markdown_path()` may be returning None for all files
- Result: 0 blocks loaded from git, agent has no pinned context

### Key Code Paths:

```
letta/services/memory_repo/memfs_client_base.py:
  - get_blocks_async() [line 114] - downloads files, converts to blocks
  - Uses memory_block_label_from_markdown_path() [line 142]

letta/services/memory_repo/path_mapping.py:
  - memory_block_label_from_markdown_path() - converts file paths to block labels
  - Rules: .md files only, skills/SKILL.md special case

letta/services/block_manager_git.py:
  - sync_blocks_from_git() [line 566] - syncs git → PostgreSQL
```

## Fixes Applied

### 1. Sidecar Patched (`~/Projects/lettabot-v017/memfs-server.py`)
Added fallback search in `_ensure_repo()`:
```python
# Search all org directories for existing agent repo
if REPO_BASE.exists():
    for org_dir in REPO_BASE.iterdir():
        candidate = org_dir / agent_id / "repo.git"
        if candidate.exists():
            return candidate
```

### 2. Dockerfile Patched (`~/Projects/letta-source-fresh/Dockerfile`)
Added after git install:
```dockerfile
RUN git config --global --add safe.directory '*'
```

### 3. Docker Compose Patched (`~/Projects/lettabot-v017/docker-compose.yml`)
Added env vars:
```yaml
- GIT_CONFIG_COUNT=1
- GIT_CONFIG_KEY_0=safe.directory
- GIT_CONFIG_VALUE_0=*
```

### 4. Copied Real Repo to Default Location
```bash
cp -r /home/ani/.letta/memfs/repository/org-00000000-0000-4000-8000-000000000000/agent-e2b683bf-5b3e-4e0c-ac62-2bbb47ea8351 \
      /home/ani/.letta/memfs/repository/default/
```

## Still Need To Investigate

1. **Why `get_blocks_async()` returns empty list despite having files**
   - Add debug logging to see what `memory_block_label_from_markdown_path()` returns
   - Check if label is None for all files
   
2. **Check if files have valid frontmatter**
   - parse_block_markdown() may be failing
   - Missing/invalid YAML frontmatter could cause silent skips

3. **Verify sync_blocks_from_git() is actually being called**
   - May need manual trigger or API call
   - POST /v1/agents/{id}/recompile helped but didn't persist blocks

## Key Insight

The recompile API returns Ani's full memory content (all system files, ~100KB+) in the response, but the blocks API shows 0 blocks. This means:

- Content EXISTS in git repo ✓
- Server CAN read it ✓
- Server is NOT converting to persistent blocks ✗

The block conversion layer (memfs_client_base.py:142) is the problem.

## Next Steps (When Resuming)

1. Add debug logging to `memory_block_label_from_markdown_path()`
2. Check what labels are generated for Ani's files
3. Verify `parse_block_markdown()` handles her frontmatter correctly
4. Trace through `get_blocks_async()` to see where blocks get lost
5. Consider calling `sync_blocks_from_git()` directly via API or code patch
