  "message": "Clean up ExecutionRequirements\n\n- remove BaseSpawn.Local; instead, all callers pass in the full set of\n  execution requirements they want to set\n- disable caching and sandboxing for the symlink tree action - it does not\n  declare outputs, so it can\u0027t be cached or sandboxed (fixes #4041)\n- centralize the existing execution requirements in the ExecutionRequirements\n  class\n- centralize checking for execution requirements in the Spawn class\n  (it\u0027s possible that we may need a more decentralized, extensible design in\n  the future, but for now having them in a single place is simple and\n  effective)\n- update the documentation\n- forward the relevant tags to execution requirements in TargetUtils (progress\n  on #3960)\n- this also contributes to #4153\n\nPiperOrigin-RevId: 177288598\n",
