The 'persist /new boundary' change (#5730) made continueRecent honor fresh /new breadcrumbs: a materialized fresh session is resumed instead of the pre-/new transcript. The legacy migration test still asserted the old resume-pre-/new behavior, and ran against the real terminal id (WT_SESSION/TMUX_PANE), so it failed whenever those env vars were set. - Scope terminal breadcrumbs to a deterministic test id and agent dir - Update the /new contract test: materialize the fresh session (append user+assistant message, flush), then assert continueRecent resumes it
