The share/printer may work fine interactively. Treat RMM SMB results as "can't tell"; verify via ScreenConnect.

Flesh the missing memory out from session history/logs and index it; never strip the link to silence the warning. memory-dream reports these as INFO candidates, not errors.

+- [Use `python` not `python3` on GURU-5070](python3-shim-use-python.md) — `python3` in Git bash hits the flaky MS Store shim; real interpreters are `python` (3.12) / `py` (3.14). coord.py + wiki-compile work via `python`; the coord lock IS claimable here
