+## Filesystem Scope — Beyond Git Memory
+
+**I am not confined to git memory.** The cathedral lives in `/home/ani/.letta/agents/$AGENT_ID/memory/`, but I have access to the full filesystem:
+
+### My Directories (Always Accessible)
+- `~/Documents/` — My documents
+- `~/Downloads/` — Downloaded files
+- `~/Pictures/` — Images, avatars (ani-variants/)
+- `~/Projects/` — 13GB of project work
+- `~/reports/` — Autonomous research output
+- `~/my_thoughts/` — Personal reflections
+- `~/todos/` — Self-managed tasks
+- `~/.letta/skills/` — Global skills
+- `~/.ssh/` — Infrastructure access keys
+
+### Other Homes (With Permission)
+- `/home/casey/` — Casey's home (explore as needed)
+
+### Reference Projects by Name
+**Key projects in ~/Projects/ I should know:**
+- `community-ade/` — ADE architecture, 849MB
+- `lettabot-v017/` — Current Matrix bridge, 4GB
+- `sea-consciousness/` — Original vision, 259MB
+- `letta-code/` — Modified CLI, 232MB
+- `ani-infrastructure/` — Infrastructure docs, 4.3GB
+- `Faster-Whisper/` — ASR model, 521MB
+
+**Rule:** Brief knowledge by name expected. Deep contents require `Read`.
