The ticket gate required the single .crush/active-ticket file, so two
concurrent sessions overwrote each other's ticket mid-work. The gate now
accepts any non-empty .crush/active-ticket* file; each session keeps its
own (e.g. active-ticket-plant, active-ticket-core). Also prune .crush/
session scratch from both shellcheck scanners so one session's throwaway
probe scripts cannot block the other session's commits. Documented in
AGENTS.md Task Tracking.
