5The generic task publisher (publish.rs; contract v2).

7One ring per program slot, and the manifest's policy deciding what meshd publishes on its own: continuous (a batch whenever the previous one completed, or topped up to `fanout` in flight with in_flight = "free"), periodic (`fanout` tasks at `hz`), on_demand (nothing; only task/req). The arg is the index 0..fanout or the view's u32 at `arg_off` (+ index). Nothing here knows any program: a new program needs no meshd change.

9Ticket rules: ticket t uses ring entry and completion slot t % 64; t may be published only once no outstanding ticket is 64 or more behind.
