Authoring workflow that turns a feature spec, risk area, or bug cluster into a session-based exploratory testing charter per Jonathan and James Bach's SBTM - frames the one-sentence mission, scopes 3-7 areas, picks a 60 / 90 / 120 min time-box, suggests tours, and wires the PROOF debrief deliverables. Per Bach, exploratory testing is "performing tests while learning things that may influence the testing" - the charter sets the mission while leaving exact steps to the tester's judgment. Use when a feature has too many unknowns to script (new feature / refactor blast-radius / bug cluster) and a session-based exploration is the right approach. Authors the charter only: the ready-to-fill charter card, session vocabulary, debrief template, and session review live in the exploratory-testing skill this workflow composes with.
