  "message": "Fine. Use manifest hash to fast-path export validation\n\nAdd a fast path for validating `export` requirements by recording and\ncomparing the exported library’s `LibraryManifest.hashForRequirements`.\n\nPreviously, `ExportRequirement.isSatisfied` walked the exported\nnamespace and compared each expected ID, even when the exported\nlibrary’s manifest had not changed. This patch short-circuits that work\nwhen the manifest hash matches the recorded value.\n\nKey changes:\n- ExportRequirement now includes a snapshot of the exported library’s\n  `hashForRequirements` and serializes it.\n- `isSatisfied()` returns success immediately when the current manifest\n  hash equals the recorded hash, skipping combinator and per-name ID\n  checks. (Missing exported libraries still report a failure.)\n- `LibraryExportRequirements.build()` captures the hash from the\n  exported library’s manifest and stores it in each requirement.\n- Bump `AnalysisDriver.DATA_VERSION` from 565 to 566 due to the binary\n  format change.\n\nImpact:\n- Avoids re-validating unchanged re-exports, reducing unnecessary work\n  in incremental analyses.\n- Maintains correctness because the hash covers exactly the\n  requirement-visible state used by validation.\n\nChange-Id: I2ecaabe45be7326ed11257a13d04a55de79f328d\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/451941\nReviewed-by: Paul Berry \u003cpaulberry@google.com\u003e\nCommit-Queue: Konstantin Shcheglov \u003cscheglov@google.com\u003e\n",
