At signing time, we don't have access to the actual build start/finish times. Setting both timestamps to nil is the correct approach because: - Using signing time would be incorrect (build happened earlier) - Using artifact mtime would be misleading (download time, not build time) - SLSA spec allows these optional fields to be omitted - Better to omit data than provide incorrect data The SLSA library uses *time.Time with omitempty, so nil values will be properly omitted from the JSON output.

00:00:00 2001 From: Leo Di Donato <120051+leodido@users.noreply.github.com> Date: Thu, 23 Oct 2025 14:48:24 +0000 Subject: [PATCH 20/21] fix: implement UploadFile method for cache wrapper types Add missing UploadFile method to pullOnlyRemoteCache and pushOnlyRemoteCache to satisfy the RemoteCache interface after UploadFile was added in earlier commits. - pushOnlyRemoteCache.UploadFile delegates to underlying cache - pullOnlyRemoteCache.UploadFile returns nil (no-op) This maintains the existing wrapper behavior patterns without changing functionality.
