Three pure cores now carry logic that was buried in git and tmux calls: _git_prep_action classifies a repo's state into none/pull/report, _order_windows sorts the window listing, and _match_window_id resolves a name to a window id. _git_is_dirty replaces the staged/unstaged/untracked check that was copy-pasted across three functions. prep_git_single and auto_pull_if_clean both route their pull-or-report choice through _git_prep_action, so the "never auto-pull a dirty repo" rule lives in one place with its own test instead of two parallel branches. sort_windows keeps its two-pass move (park high, then reassign) but hands the ordering to _order_windows, and find_window_id is now a thin tmux wrapper over _match_window_id. Each core gets a Normal/Boundary/Error set: the git-prep truth table including diverged and behind-while-dirty, the window ordering including whole-line-not-substring matching. The 42 launcher tests stay green and a live black-box run still prints the right launch command for claude and codex, so the extraction is behavior-neutral. I also ran shfmt (-i 2 -ci) to match the house style the other bin/ scripts follow. 2026-07-20T01:40:51+00:00 Craig Jennings c@cjennings.net 2026-07-20T01:40:51+00:00 urn:sha1:113e8d868fdd95b269c0cc2ce4ec265aa76b539c Brings the session launcher under characterization tests ahead of the hardening refactor, so the pure-core extractions and footgun fixes land against a green net. The tmux/git-coupled functions can't be reached by running the launcher black-box, so I wrapped dispatch in main() behind a run-vs-sourced guard: run directly it dispatches as before, sourced it exposes the functions to the tests. The net pins current behavior (record-not-spec) with a Normal/Boundary/Error set per unit: git_status_indicator across no-upstream/ahead/behind/dirty/clean, candidate discovery and filtering, selection parsing, and functional tests over create_window, find_window_id, and sort_windows ordering against a throwaway tmux server. Every tmux call runs on a private socket so nothing touches the live ai session, and the throwaway repos disable git auto-maintenance to dodge the teardown race that flaked rename-ai. Also cleared the two pre-existing shellcheck warnings on the touched paths: quoted the "@{u}" revspecs (SC1083) and marked the intentionally-literal display tilde (SC2088). Both are behavior-neutral, and the existing runtime tests confirm the launch path is unchanged.
