Cover pure functions the recent canonical Operational Trust and protection
posture work landed with no unit test:
- recovery/model posture: enum Valid, struct Clone/Validate/Payload and the
normalize/cloneTime/validOutcome/sortedUniqueStrings/compareProviderStates
helpers (20 funcs, all 0%->100%)
- operationaltrust contracts: EvidencePayloadRef/Acknowledgement/Suppression/
LifecycleTransition Validate plus LifecycleTransition/NotificationLink Clone
- cloudcp/proxytrust: ClientIP, ExtractRemoteIP, rightMostUntrustedForwardedIP
and IsTrustedProxyIP forwarded-header and CIDR parsing
- mockmodel: NormalizeBlendWeight, SeriesForTimestamps, seriesForProfile,
diskIOValue and flatValue deterministic seeded math
- updatesignature: DecodePrivateKey and HasTrustedPublicKeys
- recovery keys: ProxmoxPBSGuestLooseContinuityKey branch guards
- vmware SourceID and truenas availableAppLogContainers formatting
Test-only, contract-neutral. New *_branchcov0719_test.go files only; no source
or existing test touched.
