Terminal-session adapter (B72)

/tsm opens the v1 manager actions in v2's panel grid. Arrows select, Enter opens details or performs the action, Tab switches between actions and scrollable details, m chooses the mux for activation, r refreshes and d runs doctor. Escape returns to actions, then chat. Under 70 columns only the focused panel is shown. Removal requires y; n/Escape keeps the scaffold.

Every operation supports --json and the existing CLI envelope. Failed reports exit 1; invalid arguments exit 64. Slash arguments use the same parser: /tsm setup, /tsm activate --mux kitty, /tsm doctor, /tsm open TARGET.

As in v1 stable, plan, install and setup only save a dry-run plan. The plan contains v1's manual install suggestions; they are not executed or verified against a current release. Native worktrees/loops remain the default. Activation is opt-in, initially off, and requires a worktree-capable TSM binary on PATH or an absolute MENDCODE_TSM_BINARY. Only --version and wt --help are probed (one-second deadlines, 16 KiB output limit); raw executable output is not returned. Version ≥0.7 or successful worktree help supplies the v1 capability gate. The selected mux is saved as adapter state; it is not guessed as a CLI flag to TSM. Open/create return the v1 tsm wt BRANCH / tsm wt add BRANCH previews, with native worktree validation and a liveSync gate. No session is started or switched and no Git operation is executed.

State and plan live at <dir>/tsm/<repository-id>/{state,plan}.json; linked worktrees share the canonical Git registry identity. Optional policy lives at <dir>/tsm-policy/<repository-id>.json with {"mode":"off","liveSync":false,"neverSync":[]} defaults. Doctor checks the checkout, degraded activation and unsafe liveSync; missing Git commits are reported as a warning, matching v1. Corrupt/redirected managed files fail without being overwritten. Writes are serialized and atomic. Remove moves only the MendCode scaffold into <dir>/trash/tsm/; it preserves policy, external TSM, sessions and worktrees. No network listener/service or dependency is added. TSM queries and changes are denied to read-only peers because queries probe an external executable. Existing daemon authentication and transport remain in use.
