stroblmeandClaude Fable 5 7e4f03369b Three fewer things to remember
**The portal link puts itself back up.** It already retried a connection that
raised, but a session that ended *cleanly* — a portal restarting, a proxy
closing an idle socket — returned normally and went straight back round the
loop with no wait at all, so an engine could spin against a portal that was
merely saying goodbye politely. Every ending now reconnects on a delay, and
the delay turns on whether the attempt got as far as attaching: one that stood
up and dropped is a network event and retries at once, one that never stood up
waits longer each time. Jittered, so a portal coming back is not met by every
installation it serves in the same instant. Ping timeouts are named rather
than defaulted, since they are what bounds how long a suspended laptop's dead
socket looks alive, and the keepalive task is awaited so the reason a link
went reaches the log instead of the garbage collector.

**`fluksio enroll <code>`** is the whole command now; hub.fluksio.com is the
default and `--portal` names another. The one command run before anything
works should not need two flags.

**`fluksio run` syncs first.** The reason a run exists is usually the edit
before it, so remembering to sync was remembering to do something the computer
could do — including the worker refresh, which is what makes an edit to your
own package take effect at all. `--no-sync` opts out for a tight loop.

That last one needed discovery fixed: it only ever looked at top-level `*.py`,
so a repository whose code is in a package — the ordinary shape — found
nothing from its own root. It now descends into the packages it holds.
