Installing and Upgrading Hermes Agent: Check the Support Tier Before You Pick a Path
Hermes install paths come in three support tiers: macOS (Apple Silicon), Windows 10/11, Linux/WSL2, and Docker are Tier 1; Termux and Nix are Tier 2; pip, brew, AUR, and Intel Macs are explicitly unsupported — fixes for those won't be merged. On the upgrade side, `hermes update` snapshots state first, then compiles nine critical files after the pull and hard-resets the checkout if any fail to parse.
