forked from unom/punktfunk
The host store was keyed by `"address:port"`, which had two consequences. Editing a host's address had to re-key its record — delete the old key, write the new one — and nothing could hold a durable reference to a host at all, because the key moved whenever the host did. Profile bindings, pinned cards and `punktfunk://` shortcuts all need exactly such a reference, so the store is now keyed by a minted stable id: a lowercase UUID, the same shape Apple's `StoredHost.id` and the Rust `KnownHost.id` already carry, so a host reference is one grammar on every platform. The re-key-on-edit dance is gone; an edit is a plain save. `clipboardSync` moves from a global onto the record. It was always a decision about a HOST — whether text on this device may cross to that machine — and one global for the work box and the couch box was the wrong shape; the desktop clients have had it per-host since it shipped. It is edited from the host's Edit sheet, which is also where the profile binding will live. Both, plus the minted ids, ride ONE migration pass. The store is being rewritten anyway and every extra pass is another chance to strand somebody's hosts. It runs once against real user data, so its pure half is tested against a verbatim pre-migration blob — every host survives with its pin, paired flag and MACs, IPv6 addresses included; each lands on its own id; whatever the global clipboard setting said lands on every host, on or off; and a second pass over its own output changes nothing. Re-trusting a host now goes through `KnownHostStore.trust`, which preserves the existing record's identity and everything the user set on it. Three call sites used to construct a fresh `KnownHost` — harmless while the key was the address, but with an id it would have forked the record on every re-pair. While the wiring was open: `StreamScreen` takes an `ActiveSession` — the settings the connect actually resolved, plus that host's clipboard answer — instead of re-reading `SettingsStore` behind its own connect's back. That is also the seam profiles need.
