Terminology: this command uses 'session' throughout. The underlying workflow file (merge.md) may use 'milestone' as a legacy alias for 'session'. Treat them as equivalent: --session maps to workflow's -m, state.json.sessions[] maps to state.json.milestones[].

Flags (--session, --force, --dry-run, --no-cleanup, --continue), merge sequence, artifact sync detail, and conflict handling are defined in workflow merge.md.
