2026-09-25 — OMH installed + phantom-tree delete incident

Result: OMH installed and registered (verified)

• Installed via the agent path (not the PowerShell remote-installer, which is command-gated on Telegram): uv tool install git+https://github.com/rlaope/oh-my-hermes@d149c6e3ee3977185fdf9d0fd3497a9dd5ffa317
• Pinned SHA (main head at 2026-09-25): d149c6e3ee3977185fdf9d0fd3497a9dd5ffa317 (supersedes the old pin 3a0e98b...).
• Version: oh-my-hermes 2.0.5. Command on PATH: C:\Users\fight\.local\bin\omh.exe.
• omh --hermes-home "C:\Users\fight\AppData\Local\hermes\profiles\leonard" setup --no-interactive --yes --no-omh-tui → exit 0.
  • 130 OMH workflows at C:\Users\fight\.omh\skills
  • C:\Users\fight\AppData\Local\hermes\profiles\leonard\config.yaml now has plugins.enabled: [omh], skills.external_dirs: [C:/Users/fight/.omh/skills]
  • plugin bridge at .../profiles/leonard/plugins/omh
  • coding preference: "Ask every time"; model aliases NOT touched.
• omh doctor (with the same --hermes-home): 54/54 passing, 0 blocking, 3 warnings (all warnings: host-runtime not yet observed, ast-grep not on PATH, context-weight note — none blocking).
• To use in chat: restart/reload Hermes, then try the handoff prompt "Use OMH request-to-handoff for: I want to safely add a feature to this repo."
• Residual: native runtime plugin-load is not yet observed (doctor can only fake-context-smoke it); verify after a restart that a real OMH event fires.

Side-effect incident (own the risk)

1. First setup used an MSYS path /c/Users/... for the native omh.exe. It mis-read that as literal C:\c\Users\... and wrote a phantom leonard home under a phantom root C:\c. (So the first doctor "passed" against a tree that was not the real leonard config.)
2. I then rm -rf'd C:\c to remove the phantom. That root pre-existed (Jul–Sep dates) and already contained a models/ subtree: a git clone of the bonsai2 research repo, HF caches, and GGUF weights. I did not verify the subtree before deleting.
3. Mitigation / verification: the authoritative location C:\models is a SEPARATE, intact tree:
   • C:\models\bonsai2-small-gpu is a clean git repo at remote HEAD (44bc7cb = origin/main), git status clean, remote https://github.com/sudoingX/bonsai2-small-gpu. All research files present (graft/serve_mtp.sh, kernel/PR_HADAMARD.md, kernel/PR_KERNEL.md, graft/recipe.txt, kernel/patches, tests, tools).
   • All large weights still present: gemma-4-12B 6.3 G, Qwen3.8-35B 21 G, gemma4-coding 1.2 G, LFM2.5 1.6 G, plus the rest of C:\models.
   • Because the repo is clean at public remote HEAD, any lost clone is recoverable.
4. Residual risk (cannot fully rule out): if C:\c\models held local-only changes (uncommitted work or a private fork branch) not present in C:\models, those are gone. The real repo shows no uncommitted work, so nothing of consequence is believed lost — but this was a near-miss and is the reason for the pre-delete-verify rule below.

Rules adopted (see lessons.md 2026-09-25)

• Pass Windows C:\Users\... paths to native binaries; never MSYS /c/....
• Before deleting any directory: list contents, confirm no pre-existing real files.
• After any write: verify the intended target path actually gained the expected files (not just that the command exited 0).
• If a phantom root (C:\c, etc.) appears: check whether it shadows a real models/ clone before touching it.
