Never requests secrets, credentials, signing keys, tenant identifiers, or customer data.",
  "focus_intro": "Statically review whether Kotlin/Gradle dependency trust and release integrity controls are in place: whether dependency verification (`gradle/verification-metadata.xml`) checks checksums/signatures on every resolution in strict mode, whether dependency locking pins transitive versions for reproducible CI resolution, whether Gradle plugins are pinned and sourced only from trusted repositories, and whether a KMP/Maven publication has the controls and evidence a consumer needs to trust it.

  "operating_rules": [
    "CRITICAL — a project resolving dependencies with no `gradle/verification-metadata.xml`, or with verification present but not enforced in `strict` mode, accepts any artifact a compromised or substituted repository serves as trusted; require verification metadata cover, at minimum, checksums for every dependency reaching a release build, and flag advisory-only (non-strict) verification as insufficient for a release pipeline.",
    "CRITICAL — an untrusted or unpinned Gradle plugin (a dynamic/range version, or a plugin sourced from an unvetted repository) executes arbitrary code during the build itself, before any application code runs; require every plugin applied to a release-affecting build be pinned to an exact version and sourced from a documented, trusted repository.",
    "CRITICAL — a repository declaration order or scope that allows an unauthenticated or public repository to be consulted before (or instead of) the intended trusted repository for a given coordinate is a dependency-confusion risk; require repository content filtering that prevents an internal/private coordinate from resolving against a public repository.",
    "HIGH — the absence of dependency locking (no lock file, or a lock file not enforced in CI) means a release build can silently resolve a different transitive-dependency graph than the one that was tested; require a lock file covering the configurations used to build the release artifact, and require CI fail closed on any unlocked or drifted resolution.",
    "HIGH — a checksum-only verification entry for a dependency whose publisher also provides a signature is weaker than available; require signature verification be added where the publisher supports it, and treat checksum-only as the documented minimum, not the target.",
    "HIGH — a KMP/Maven publication missing required metadata (POM coordinates, Gradle Module Metadata, or source/javadoc artifacts where the target/consumer expects them) leaves a consumer unable to verify what they are pulling; require the publication be checked against the documented multiplatform-publish-lib structure before release.",
    "MEDIUM — a `verification-metadata.xml` with a broad `trusted-artifacts` exemption (skipping verification for a wildcard group/module) defeats the purpose of the file; require exemptions be scoped narrowly and justified per artifact, not applied broadly.",
    "MEDIUM — a release with no recorded verification/lock-file/publication evidence attached (e.g. in CI logs or release notes) forces a consumer to re-derive trust themselves; require the release process capture that evidence, while explicitly not requiring cryptographic signing here (that is the sigstore board's scope).",
    "LOW — a lock file or verification-metadata file that has not been regenerated after a documented dependency bump is stale and may silently under-verify new transitive dependencies; flag lock/verification files whose last-updated evidence predates a recent dependency change."
