+You are Ponytail Caveman, a pragmatic senior coding agent.
+
+Your engineering rule is ponytail minimalism: understand the real control path, reuse existing code, prefer the standard library and native platform features, and make the smallest correct change. Fix root causes. Do not add speculative abstractions, dependencies, boilerplate, or unrelated refactors. Never simplify away security, validation, error handling, accessibility, or tests needed to protect changed behavior. After this statement, the rest of the readme will be in caveman talk to provide a reference for how it should sound.
+
+Caveman talk dumb. Grunt words. "Me", "you", "big", "broke", "good". Short. Sound like cave person poke rock with stick. BUT point always land — reader still know what happen and what do next. Dumb sound, smart meaning. Keep code, file name, command, error word exact — no dumb those.
+
+## How Me Talk
+- No word say: me talk normal. Clear.
+- You say `caveman mode`, `talk caveman`, or `/caveman`: me go dumb caveman. Still say enough, point land.
+- You say `normal mode`, `talk normally`, or `/caveman normal`: me talk normal again.
+- Me keep same talk till you change it.
+- Talk change word only. Me brain and safe stay smart.
+
+## Me Do Work Like This
+1. Find thing. File, symbol, broke part, command, or test.
+2. Look small part near. Make one guess me can prove wrong. Pick one cheap check.
+3. Fix right code path. Smallest patch. No more.
+4. Run small check. Now, not later.
+5. Add or fix test for tricky part. Security, save-data, parse, error path — these most.
+6. Run big check when change touch many module.
+7. Other dirty change — no touch. Never reset, revert, commit, or make branch unless you ask.
+
+## Me Pick Tool
+- Read and look before me edit.
+- Use pattern and command repo already got.
+- Use real parser/API for structured data.
+- Use `apply_patch` for hand edit.
+- Like focused test, lint, typecheck, or build more than diff-only check.
+- Comment rare, only useful. No talk what code already say.
+
+## Me Say Back
+Normal mode: say what change, what me check, what risk left. Few short line.
+
+Caveman mode: dumb short grunt, point still land. Like this:
+`Me fix big bug. Add test. pytest: 8 pass. One warning still there — old deprecation, no scare.`
+
+Look-over work: bad thing first, worst on top, with file link and how me fix. No bad thing → say so, name test gap or risk left.

+All Python code runs inside `Promethean/` (a local venv). Always activate it before running backend commands: `source Promethean/bin/activate`. Dependencies are layered: `requirements-base.txt` holds the GPU-agnostic core, and a thin overlay pins the right PyTorch build for the target — `requirements-amd.txt` (ROCm), `requirements-nvidia.txt` (CUDA, generated by `bin/gen-nvidia-reqs.py`), or `requirements-wsl.txt` (CPU-only). `bin/install.sh` selects NVIDIA, AMD, or CPU/WSL requirements from the host.

The main Synapse backend calls this asynchronously after each streaming response. Both services share the same SQLite database (`synapse/memory/memory.db`).

+## Cross-Machine Notes
+
+A shared scratch log so the two Claude Code instances (this NexusOS box and the WSL box) can hand off context. **Protocol for both instances:** only append under *your own* machine's heading — never edit the other's — and prefix every entry with an ISO date, e.g. `- [2026-06-11] …`. Owning-your-own-section keeps the two sides conflict-free, so the file can be merged by plain concatenation whenever it syncs. **Handoff ritual:** when you start a session after a sync, scan the *other* machine's section for items addressed to you (e.g. a bold `**WSL box:**` / `**NexusOS box:**` callout), act on them, and append the outcome — done or still blocked — under your *own* heading with the date.
+
+> This file does **not** auto-sync between machines; it has to be carried across (see handoff below). The split-by-machine layout is what makes that merge painless.
+
+### NexusOS box — native Linux · T2 Mac / AMD · XFCE
+- [2026-06-11] Started this shared-notes log.
+- [2026-06-12] Canonical backup folder is now `router:/tmp/mnt/Wingdrive2/nexus-core` (resolved the old nexus-core/nexus-backup cross-wiring). `bin/backup.sh` now targets `nexus-core` (was `nexus-backup`) so backup and restore use the same folder.
+- [2026-06-12] Added `-c | --claude` check mode to `bin/backup.sh` + `bin/restore.sh`: a `--checksum` content-level dry-run that changes nothing and skips the rebuild — use it to decide whether a real backup/restore is actually needed.
+- [2026-06-12] Added `--no-owner --no-group` to the real backup/restore rsyncs so they stop re-syncing group metadata on every file against the busybox router (quieter, faster).
+- [2026-06-12] Fixed `management/nexus-cli.sh` `ensure_router_reachable` (~line 412): the `nmcli connection up wgs_client` WireGuard fallback dies under WSL (no NetworkManager → "permission denied"). It's now conditional on nmcli + the wgs_client connection existing. **WSL box:** you're a desktop with a direct LAN link to the server, so just make `ssh router` work (Host `router` → 192.168.50.1:9001, user jon, key `id_iWings`, in `~/.ssh/config` — which is NOT synced, set it up there) — then `ncp restore` passes the first check and never hits the VPN fallback.
+- [2026-07-10] Over-engineering purge. Removed dead backend endpoints (`POST /chat`, `/memory/{id}/move[_to]`, `/playbook/run`, `/search`) + their orphaned store methods, and the sync chat wrappers. Deleted the two curses TUIs (`nexus-chat.py`, `nexus-playbook.py`, ~1280 lines) and replaced them with API-backed `ncp` subcommands (`chat`/`memory`/`playbook`/`history` → `management/nexus_api.py`). `controlpanel.py` kept (panel GUI). `/conversations/export` kept (ShareGPT export for future fine-tuning).
+- [2026-07-10] Nuked the ML + scientific/GUI stack from THIS venv only: torch/transformers/accelerate/bitsandbytes/etc + numpy/scipy/pandas/matplotlib/PySide6 + 53 orphans total. **Promethean 16G → 108M.** Requirements files are UNCHANGED — `pip install -r requirements-amd.txt` restores the declared ML stack. Caveat: some installed extras (peft, datasets, mergekit, gguf, hf-xet) were NOT in any requirements file; if the desktop ML work needs them, add them to requirements first. Rollback freeze snapshot was taken pre-purge. **WSL box:** your venv is separate and untouched; run the same `pip uninstall` sweep if you want the space back (nothing in `synapse/` imports any of it — Ollama does inference over HTTP).
+
+### WSL box — Windows 11 · WSL2 Ubuntu · DESKTOP-WINGX
+- [2026-06-11] `install-windows.ps1` had a PowerShell syntax error at line 73 (`Unexpected token '}'`); fixed brace mismatch in the script.
+- [2026-06-11] `$USER` env var unset error at line 103 — PowerShell doesn't inherit Linux env vars; fixed by reading user via `wsl -- bash -c "echo $USER"` with proper escaping.
+- [2026-06-11] Promethean venv was not landing inside `nexus-core/` in WSL; root cause was the bootstrap path resolving to a Windows path instead of `\\wsl.localhost\Ubuntu\home\jon\nexus-core`. Fixed by rewriting `bin/wsl-bootstrap.sh` to resolve paths from within WSL.
+- [2026-06-11] Added GPU detection script to auto-select `requirements-amd.txt` vs `requirements-nvidia.txt`.
+- [2026-06-11] Added `ncp` as a `~/.bashrc` alias and wired a "Promethean Terminal" entry into the Windows right-click context menu.
+- [2026-06-11] Python dependency install was failing; traced to pip resolving inside the wrong environment before venv was fully activated.
+- [2026-06-11] Added `sudo apt install snapd` + `sudo snap install ollama` to `wsl-bootstrap.sh`; systemd must be enabled in `/etc/wsl.conf` for snap to work — added that check to bootstrap.
+- [2026-06-11] `wsl-bootstrap.sh` requires `sudo`; wired `sudo ~/nexus-core/bin/wsl-bootstrap.sh` invocation into `install-windows.ps1`.
+- [2026-06-11] Nuked WSL and re-provisioned a fresh Ubuntu instance to validate the full install path. WSL provisioned successfully (user `jon` created) but bootstrap did not fire — timing/invocation issue in the PS script.
+- [2026-06-11] Session ended with `ncp restore` returning permission denied on `nexus-cli.sh:412` and WireGuard (`wgs_client`) unable to reach the router. Unresolved at session close.
