description: On GURU-5070, `python3` in Git bash resolves to the flaky MS Store shim (errors with "run without arguments to install from the Microsoft Store"). Use `python` (real 3.12.10) or `py` (3.14.5) instead — affects coord.py, wiki-compile, any python tooling.

On **GURU-5070** (verified 2026-06-11), invoking `python3` from the **Bash/Git-bash** tool
hits the **Microsoft Store app-execution-alias shim**
(`~/AppData/Local/Microsoft/WindowsApps/python3.exe`), which can error with
`Python was not found; run without arguments to install from the Microsoft Store`. So
`PY=$(command -v python3 || command -v python)` picks the SHIM first (it exists as a file,
so `command -v` succeeds) and breaks.

**Real interpreters that work** (both from Bash and PowerShell):
- `python` -> 3.12.10 (`~/AppData/Local/Programs/Python/Python312/python.exe`)
- `py`     -> 3.14.5 (the Windows launcher; `py -0p` lists all)

**Fix / how to apply:** when a skill or script needs Python on this box, run **`python`**
(or `py`), NEVER `python3`. This affects the `coord` skill
(`.claude/skills/coord/scripts/coord.py` — verified working via `python`, reaches the live
coord API at 172.16.3.30:8001) and `/wiki-compile` (which hardcodes `python3 -c "import
urllib..."` for URL-encoding and `command -v python3`). When a skill hardcodes `python3`,
substitute `python`. The coord per-article lock IS claimable here — do not skip it as
"no local Python". Related: [[gururmm-session-logs-submodule-save]].
