  "message": "Return REMOTE_CACHE_EVICTED exit code on ThinLTO imports cache eviction.\n\nThinLTO backend compilation reads `.imports` files during Skyframe input discovery prior to spawn execution. When remote cache eviction drops an imports file, `LtoBackendAction.computeImports` caught the cache miss as a generic `IMPORTS_READ_IO_EXCEPTION` (exit code 1). Because Bazel only triggers `--experimental_remote_cache_eviction_retries` when an action returns `REMOTE_CACHE_EVICTED` (exit code 39), builds fail permanently instead of retrying.\n\nIn `LtoBackendAction.computeImports`, check if an `IOException` reading the imports file is a `CacheNotFoundException` or `BulkTransferException` cache miss. If so, return `Spawn.Code.REMOTE_CACHE_EVICTED` so that input discovery failures from evicted cache entries trigger build retries.\n\nTested:\nAdded `discoverInputs_cacheNotFoundException_throwsRemoteCacheEvictedCode` and `discoverInputs_bulkTransferException_throwsRemoteCacheEvictedCode` in `LtoBackendActionTest`.\nPiperOrigin-RevId: 971771054\nChange-Id: I6c9b84c9a55d727cd930319178a946332df2d977\n",
