  "issue": "Persistent radio search objective promised station discovery from another fixed clue folder despite default distinct non-radio discovery threshold; stage5 retained an obsolete escape-boundary description.",
  "change": "Conditional persistent advice to retain locked documents and identify distinct non-radio sites, excluding starting clue markers; automatic reread and direct visual fallback remain. Stage5 states all rescue transports must stay airborne for 30 continuous seconds.",
  "synchronization": "No gate count/settings reads, replication, gameplay timing or inventory behavior changes. Conditional wording supports disabled gate and sparse terrain clamping.",
  "validation": "Three unchanged focused tests passed. No new test assertions or registration. No native engine, physical flight or UI rendering proof.",
  "preservation": "Live ObjectiveText baseline unchanged at proposal seal; unrelated current edits not touched."
