Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff obfuscated-file:locale-data/am.js AI (source-diff): Auto-generated locale data JSON for Intl.DateTimeFormat polyfill. Long lines are dense i18n data, not obfuscation. ai
provenance no-provenance AI (provenance): Formatjs packages have not historically used Sigstore provenance; absence is a process gap, not a security indicator for this well-established package. ai
provenance missing-githead AI (provenance): Established formatjs package with clean history; missing gitHead reflects a CI/publish environment change, not a security concern for this package. ai
source-diff obfuscated-file:add-golden-tz.js AI (source-diff): Generated timezone transition data file for Intl.DateTimeFormat polyfill; long lines are pipe-delimited zone records, not obfuscation. ai
source-diff obfuscated-file:locale-data/agq.js AI (source-diff): Generated locale data file for Intl.DateTimeFormat polyfill; long lines are compact JSON locale data, not obfuscation. ai
source-diff obfuscated-file:locale-data/ak.js AI (source-diff): Generated locale data file for Intl.DateTimeFormat polyfill; long lines are compact JSON locale data, not obfuscation. ai
source-diff large-new-source-files AI (source-diff): New files are generated locale and timezone data for a comprehensive Intl polyfill; large file count is expected when adding full locale coverage. ai
source-diff source-size-tripled AI (source-diff): Size increase is due to addition of comprehensive locale data and timezone data files for the Intl.DateTimeFormat polyfill, not injected payloads. ai
source-diff obfuscated-file:add-all-tz.js AI (source-diff): Generated timezone transition data file for Intl.DateTimeFormat polyfill; long lines are pipe-delimited zone records, not obfuscation. Pattern is stable for this package. ai
source-diff obfuscated-file:lib/src/data/all-tz.js AI (source-diff): Generated timezone abbreviation/offset lookup table; compact data encoding is expected for this i18n polyfill package. ai
source-diff obfuscated-file:src/data/all-tz.js AI (source-diff): Generated timezone abbreviation/offset lookup table; compact data encoding is expected for this i18n polyfill package. ai
source-diff obfuscated-file:locale-data/af-NA.js AI (source-diff): Generated locale data file calling __addLocaleData with structured JSON; @generated comment confirms build artifact, not obfuscation. ai
source-diff obfuscated-file:locale-data/af.js AI (source-diff): Generated locale data file calling __addLocaleData with structured JSON; @generated comment confirms build artifact. ai
phantom-deps phantom-dep:@formatjs/intl-localematcher AI (phantom-deps): Same-org dependency declared in package.json; phantom detection is a false positive for monorepo packages that may use it indirectly. ai
bogus-package bogus-package AI (bogus-package): Monorepo package; README and docs live at repo root. Empty index.js is a re-export shim pattern common in FormatJS packages. ai
source-diff obfuscated-file:src/data/all-tz.generated.js AI (source-diff): File is @generated IANA timezone data (abbreviations + offsets). Long lines are data strings, not obfuscation. Consistent with the package's datetime polyfill purpose. ai
provenance publisher-changed AI (provenance): FormatJS migrated to GitHub Actions CI publishing; SLSA provenance attestation confirms legitimate CI/CD pipeline. This transition is permanent and expected for all future versions. ai
publish-pattern dormant-publish AI (publish-pattern): Large OSS monorepo; dormancy periods are normal. SLSA attestation rules out account takeover. ai
