docs: the data channel is live - phase 3 verified with a real agent - #28
Merged
Conversation
The app hosts the MCP conversation on a socket it owns, proxies every frame, and grew its first panels: a live result table (SELECT column order preserved), an activity feed, and the executed SQL as headline. Verified on the hard dataset with real Claude Code: the fan-out question answered correctly with the separate-grain CTE pattern visible in the panel, and in open-ended analysis the agent spontaneously caught both planted data-quality traps (the 0.00 open invoice, and invoice 17's net_amt 609 vs amt_txt '600.00 USD' - the stale legacy column). Also recorded: the first real session found three defects (panel squeeze-out, mystery-pill empty state, a crash on the second differently-shaped result) that the automated wire test could not see. Both kinds of check stay.

net_amt609 vsamt_txt"600.00 USD" - the stale-legacy-column trap working in the wildWhat the first session's failures taught
Three defects found by a human using it, none by the automated wire test: the panel squeezed out by the terminal (no holding priorities), an empty striped table reading as mystery pills, and a crash on the second differently-shaped result (
addTableColumnsynchronously queries the delegate against stale row indices). All fixed and re-verified - and the lesson recorded: both kinds of check stay.🤖 Generated with Claude Code
