+## Update: 19:48 UTC — Python Fix + CLAUDE.md Continued
+
+### Summary
+
+Fixed Windows python3 Store alias errors (exit code 49) burning tokens on every Python call. Also committed previous CLAUDE.md optimization work.
+
+### Root Cause
+
+Windows Store app execution aliases for `python.exe` and `python3.exe` were intercepting calls and returning exit 49 instead of running Python. Fix was two-part:
+1. Code: replace `python3` with `py` (Windows launcher) or `jq` throughout all scripts/docs
+2. System: Mike disabled the Store aliases in Settings > Apps > Advanced app settings > App execution aliases
+
+### Files Changed
+
+**ClaudeTools repo (936ea49):**
+- `.claude/OLLAMA.md` — reachability check: `python -c` → `jq -r`, one-liner: `python3` → `py`
+- `.claude/commands/syncro.md` — `python` → `py`
+- `.claude/scripts/sync.sh` — fallback loop: `python3 python` → `py python3 python`; also updated error message
+- `.claude/skills/1password/references/op_commands.md` — all `python3` → `py`; JSON one-liners → `jq`
+- `.claude/skills/1password/references/secret_references.md` — all `python3` → `py`; field list → `jq`
+- `.claude/skills/1password/scripts/check_setup.sh` — vault list: `python3` → `jq`
+- `.claude/skills/1password/scripts/env_from_op.sh` — item lists → `jq`; vault/title extraction → `jq`; heredoc: `python3 -` → `py -`
+- `.claude/skills/1password/scripts/store_secret.sh` — item ID + vault name extraction: `python3` → `jq`
+- `.claude/skills/remediation-tool/scripts/get-token.sh` — fallback loop: `python3 python py` → `py python python3`
+- `.claude/DATABASE_FIRST_PROTOCOL.md` — `python -c` → `jq -r`
+- `.claude/settings.local.json` — added `"Bash(py:*)"` to allowlist
+
+**Vault repo (4590370):**
+- `scripts/vault.sh` — fallback loop: `python python3 py` → `py python python3`
+
+### Python State on DESKTOP-0O8A1RL
+
+| Command | Status |
+|---|---|
+| `python3` | BROKEN — Store alias disabled, now fails cleanly |
+| `python` | BROKEN — Store alias disabled |
+| `py` | WORKS — Windows launcher at `C:\Windows\py.exe` |
+| `jq` | WORKS — `C:\Users\guru\AppData\Local\Microsoft\WinGet\Links\jq.exe` |
+| Python install | `C:\Program Files\Python314\python.exe` (also Python312 in user AppData) |
+
+### Memory Saved
+
+Added `feedback_python_windows.md` to `.claude/memory/`: use `py` not `python3`, prefer `jq` for JSON.
