  "note": "Transport capture of the Claude Code session inbox, run on Claude Code 2.1.282, macOS arm64, 2026-09-25, before any ACC code used it. A receiving interactive TUI session ran from the real executable in auto mode with ACC 0.7.0 hooks installed and no Channel. A separate process, not a child of the receiver, wrote one JSON line per connection to the socket the session registry named, with no auth line and no token. Session ids, paths, pids and message text are redacted; outcomes are read from the receiver's own transcript records and ACC's store events.",
