User-facing how-to distinct from the design spec: the port-probe reachability
gate, one-time Termux setup + tar-over-ssh sync, the hh launcher grammar,
per-directory direnv auto-host, the mobile web console, phone-capture.sh routes
(non-root file/term/webshot vs ADB shot/screen), and the Fairphone skill
ship-list. Linked from termux-operator.md.

Phased plan (P0 dependency spike → P1 read-only presence → P2 sandbox drive →
P3 remote-provider autonomy → P4 persistence) for joining a room as a user from
Termux. Grounded in the real SRP/Fernet/ws client and the operate provider path.
Covers the srp aarch64 build risk + pure-Python SRP fallback, the cryptography
pin workaround, and Tailscale / reverse-SSH / port-forward reachability.
