Dashboard shows every Python run and replays the whole session

Every python_exec and python_eval the ix MCP runs now appears on the dashboard as its own card: a box of the run’s captured stdout and stderr, with the source behind it (a show source toggle, or the focus view). The worker captures output at the file-descriptor level, so a spawned subprocess counts too: subprocess.run(["echo", "hi"]) shows hi, not nothing. Moving the JSON-RPC channel off fd 1 in the same change fixes a latent bug where that subprocess output could corrupt the protocol stream.

The resource model is now general. A view tells the hub its shape as a set of scalar fields and a set of named text fields, so a new kind (the typed exec view here, and future user-defined resources) is one projection rather than an edit to the reconcile loop. Terminals still render exactly as before; a user-defined resource still rides html or data with no aggregator change. Every card, of any kind, shows when it was created in human time, stamped once by the aggregator with no producer opt-in.

The board is also a recording. The hub timestamps every change, the browser keeps the full history, and a timeline bar scrubs to any past moment, plays it back at 1×–8×, or follows the live tail like a livestream. The aggregator persists the recording to disk ($XDG_STATE_HOME/ix-dash/recordings), serves saved sessions at /recordings and /recording/<id>, and the share button copies a deep link to the exact moment. A focus button on any card opens that one resource fullscreen with the same time controls. Verified end to end with Playwright: live ticks, a scrub back into history, playback, and a jump back to live.
