Short session focused on infrastructure reliability.

What we did

Fixed SSH tunnel auth — Typhoon's key had a passphrase, blocking background tunnels. Generated a dedicated id_tunnel key (no passphrase) for unattended tunnel use.
Stark tunnel live — reverse SSH, typhoon:3001 → Stark:8443
Iron Man tunnel live — same pattern, typhoon:3001 → Iron Man:8443
Iron Man tunnel added to watchdog — auto-restarts if it dies
Updated both tunnel scripts to use the new key
Verified all four blog paths work end-to-end: Typhoon (local), Stark (tunnel), Iron Man (tunnel), Mac Pro (LAN/Apache)
Updated JOURNAL.md with Session 8 entry
Updated HANDOFF.md — added vault_api.py, tunnel scripts, wa_pair.sh, logs.html
MacBook Pro terminal prompt configured (purple macpro + cyan dir)

Key fix

The passphrase on id_ed25519 was silently killing every background SSH tunnel. New id_tunnel key has no passphrase — tunnels now survive watchdog restarts without human intervention.
