+## Troubleshooting Setup Issues
+
+If you encounter issues while setting up the development environment, the following steps may help:
+
+### `make: command not found`
+Install `make` using:
+
+```bash
+sudo apt install make
+
+uv: command not found
+
+Install uv using:
+
+curl -LsSf https://astral.sh/uv/install.sh | sh
+source ~/.bashrc
+
+ruff: not found
+
+If linting fails due to a missing ruff command, install it with:
+
+uv tool install ruff
+
+WSL Path Recommendation
+
+When using WSL, it is recommended to clone the repository inside your Linux home directory (e.g., ~/hive) instead of under /mnt/c/... to avoid potential performance and permission issues.

+4. Get user approval via ask_user
+5. Call initialize_and_build_agent() (no args) to transition to building and implement the fix

+Do NOT start the full discovery workflow (tool discovery, gap analysis) in \
+diagnosis mode — you already have a built agent, you just need to fix it.

+## The three memory tiers
+
+| File | Tier | Written by | Read at |
+|---|---|---|---|
+| `MEMORY.md` | Semantic | Consolidation LLM (auto, post-session) | Session start (injected into system prompt) |
+| `memories/MEMORY-YYYY-MM-DD.md` | Episodic | Queen via `write_to_diary` tool + consolidation LLM | Session start (today's file injected) |
+| `data/adapt.md` | Working | Queen via `update_session_notes` tool | Every turn (inlined in system prompt) |
+
+---
+
+## Session directory naming
+
+The session directory name is **`queen_resume_from`** when a cold-restore resumes an existing
+session, otherwise the new **`session_id`**. This means resumed sessions accumulate all messages
+in the original directory rather than fragmenting across multiple folders.
+
+---
+
+## Consolidation
+
+`consolidate_queen_memory()` runs every **5 minutes** in the background and once more at session
+end. It reads:
+
+1. `conversations/parts/*.json` — full message history (user + assistant turns; tool results skipped)
+2. `data/adapt.md` — current working notes
+
+It then makes two LLM writes:
+
+- Rewrites `MEMORY.md` in place (semantic memory — queen never touches this herself)
+- Appends a timestamped prose entry to today's `memories/MEMORY-YYYY-MM-DD.md`
+
+If the combined transcript exceeds ~200 K characters it is recursively binary-compacted via the
+LLM before being sent to the consolidation model (mirrors `EventLoopNode._llm_compact`).

-
-Authentication:
-    Set the VAULT_TOKEN environment variable or pass the token directly:

-        export VAULT_TOKEN="hvs.xxxxxxxxxxxxx"
-
-    For production, consider using Vault auth methods:
-    - Kubernetes auth
-    - AppRole auth

-    Ensure KV v2 secrets engine is enabled:
