  "message": "[9.4.0] Deduplicate repository mappings before sorting (#32066) (#32269)\n\nRepoMappingManifestAction deduplicates repository names in a HashMap\nbefore sorting the distinct names. It preserves the first mapping for a\nduplicate repository and keeps both expanded and compact output order;\nidentical entry maps are still grouped for compact manifests.\n\nIn the original 32,768-package, 256-manifest fixture with 1,024\nrepositories, manifest generation improved from 1.829 to 1.483 s. The\n32-repository control was unchanged. The complete patch matches the\noriginal and git diff --check passes upstream.\n\n@fmeum\n\nCloses #32066\n\n\nCOPYBARA_INTEGRATE_REVIEW\u003dhttps://github.com/bazelbuild/bazel/pull/32066\nfrom dzbarsky:dzbarsky/upstream-bazel-151\na9a0cf8e79ae442f3d96662dcbb967e4160c1bdb PiperOrigin-RevId: 1008281270\nChange-Id: I08f73a5516830412c2d81bf327db079c558ca4eb\n\n\u003c!--\nThank you for contributing to Bazel!\nPlease read the contribution guidelines: https://bazel.build/contribute\nand guidelines for AI-assisted contributions:\nhttps://bazel.build/contribute/ai-assisted-contributions\n--\u003e\n\n### Description\n\u003c!--\nPlease provide a brief summary of the changes in this PR.\n--\u003e\n\n### Motivation\n\u003c!--\nWhy is this change important?
