Provenance

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures No source commit

Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
phantom-deps phantom-dep:use-reduce-memo AI (phantom-deps): Likely used transitively or via re-export pattern; stable false positive for this package. ai
source-diff net-exec-file:dist/chunk-LIZ64UIL.mjs AI (source-diff): Minified ESM bundle chunk; same pattern as main bundle. ai
source-diff large-new-source-files AI (source-diff): Build system refactor from babel/tsup scripts to tsup-only produces many chunk files; expected for this package. ai
source-diff obfuscated-file:dist/botframework-webchat-api.decorator.js AI (source-diff): Standard tsup minified bundle output for this Microsoft package; not obfuscation. ai
source-diff obfuscated-file:dist/botframework-webchat-api.hook.js AI (source-diff): Standard tsup minified bundle output for this Microsoft package; not obfuscation. ai
source-diff obfuscated-file:dist/botframework-webchat-api.js AI (source-diff): Standard tsup minified bundle output for this Microsoft package; not obfuscation. ai
source-diff obfuscated-file:dist/botframework-webchat-api.decorator.mjs AI (source-diff): Standard tsup minified bundle output for this Microsoft package; not obfuscation. ai
source-diff net-exec-file:dist/botframework-webchat-api.js AI (source-diff): Minified React bundle; network calls are fetch/XHR for chat, dynamic code is Function('return this') global detection pattern. ai
source-diff net-exec-file:dist/chunk-3YCFZWVR.js AI (source-diff): Minified React bundle chunk; same pattern as main bundle. ai
source-diff net-exec-file:dist/chunk-A6GQOZT3.js AI (source-diff): Minified React bundle chunk; same pattern as main bundle. ai
source-diff net-exec-file:dist/chunk-L5VFUNB4.js AI (source-diff): Minified React bundle chunk; same pattern as main bundle. ai
source-diff net-exec-file:dist/chunk-5HALOM2E.mjs AI (source-diff): Minified ESM bundle chunk; same pattern as main bundle. ai
source-diff net-exec-file:dist/chunk-FA2GLWPN.mjs AI (source-diff): Minified ESM bundle chunk; same pattern as main bundle. ai
dependencies unvetted-dep:globalize AI (dependencies): globalize is a well-known i18n library explicitly used in this package's build pipeline; stable false positive for this package. ai
phantom-deps phantom-dep:redux AI (phantom-deps): redux is explicitly declared in dependencies; phantom-dep heuristic is a false positive for this package. ai

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

INFO Publisher changed: botframework → microsoft1es (on 2026-05-25, known maintainer) provenance

This version was published by a different npm account (microsoft1es) than the most recent previously approved version (botframework) on 2026-05-25, but microsoft1es is listed as a maintainer on prior approved versions (matched on name). This looks like a manual publish by a known maintainer rather than a publisher change. Recorded as INFO for audit trail.
