Keys: Enter open, Tab mark, Ctrl-S return marked rows, Ctrl-D\ndownload to dest_dir, Ctrl-E jump to all sessions in the project, Ctrl-O\nopen in the web UI, Esc back. Entry can be seeded with project/subject/\nexperiment ids to skip levels.\n\nModal, R-orchestrated design: R holds navigation state and invokes fzf once\nper level, so data is fetched in-process (no cold R per keystroke) and all\nlogic is unit-testable. The single fzf I/O seam (.fzf_run) is injectable, so\nrendering, arg building, result parsing, previews, and the navigation state\nmachine are covered by offline tests with a scripted fake runner; one\nintegration test exercises the real fzf binary when present.\n\n.fzf_run quotes args because system2() does not, which is required for the\nspace-containing --preview command to survive the shell. fzf declared as an\noptional SystemRequirements.\n\nCo-Authored-By: Claude Opus 4.8 (1M context) \n", "time": 1780405785 }, "_maintainer": { "name": "Bradley Buchsbaum", "email":
